advantages of lcd displays made in china

As is known to all, in the past 40 years, China has made remarkable achievements in its industry. With the establishment and improvement of a modern industrial system with complete categories, China has long been the world’s largest manufacturing country.

This is mainly because China has a large population, about the same as the rest of the developed world put together, but it has not yet developed to the point where services account for a large proportion. Because China has a large population and a large number of employed people, labor is cheaper than in other countries. Foreign enterprises can take advantage of China’s labor force by putting their products into production in China, which not only increases the employment rate of Chinese people but also saves a lot of costs in the production of products. Therefore, made in China is so popular.

A guy on Quora mentions that”If you import a lot of raw Material from broad, it will cost a lot of money, but China has a very special weapon: infrastructure. Since the demand for products (mostly commodities) drives demand for raw material, that drives demand for infrastructure to route these raw materials effectively and cheaply. Unlike India, China has that infrastructure and system, and so raw material can flow in large batches and routed effectively to minimize cost.”

It is also true that in the eyes of foreign companies, Chinese products in almost any field can be produced. China’s development in the production field in recent years is very comprehensive, including raw materials, production, logistics, trade, and other supporting industrial chains, which can be said to be very complete. Therefore, foreign enterprises can find a complete industrial chain in a very short time when they come to China, so the reputation of Chinese manufacturing is also very good.

When it comes to cheap Labour, it is much cheaper in south-east Asia than in China. But why is China so popular? This involves the quality of the product. The reason why the labor force in many countries in southeast Asia is cheap is mainly that the economic level of these countries is not high, so no matter the production technology or technological level is inferior to China. To ensure the quality of their products, foreign companies naturally prefer to choose China.

In terms of product production efficiency, China is hard to compare with many other countries. According to relevant data, domestic product manufacturing efficiency is the highest in the world. On the one hand, this is because China’s factories have more comprehensive equipment and a high level of science and technology, which can shorten the production cycle of products. On the other hand, it is because of the high quality of Chinese workers, strong learning ability, and developed transportation, which also speeds up the operation of all aspects of product production.

In order to export more products to other parts of the world, the Chinese government has only a VAT system and only taxes value-added services. As a result, production costs are much cheaper than in other countries. On the other hand, the United States and some other developed countries do not impose low import tariffs on Chinese goods.

It is believed that with the continuous development of Chinese manufacturing and science and technology, made-in-china manufactures will become more popular in the future.

In this article, we are looking at the benefits of looking for Chinese TFT LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with STONE Tech.

There is no doubt that China has taken the mass manufacturing business by storm. There are few products that we can encounter in our lives that don’t have the words ‘Made in China’ scribbled underneath. There is a glut of products that are mass-manufactured by the Chinese and then shipped out internationally to be sold.

Handbags, wallets, phone cases, and other similar items have become the favorites of wholesalers and bulk buyers. These products are directly sold to end consumers. However, the fascinating thing about the Chinese production and manufacturing business is that it does not only cover the end-consumer products. Rather, you can also acquire raw and basic materials needed for the further manufacturing of goods and products. One such product is LCD displays.

LCD displays have become something of a necessity in today’s world of tech advancement. Many things in our daily life have been automated, and are operated using an interactive user interface. For these kinds of machines and gadgets, LCD displays are typically necessary.

In this article, we are looking at the benefits of looking for Chinese LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with Stoneitech.com.

STONE Tech is an LCD manufacturer located in Beijing, China. It was founded back in 2010, and it has been developing TFT LCD display modules ever since. These modules can be used for a variety of different machines including electric equipment, precision instruments, and civil electronics etcetera.

One of the main benefits that you get with Stoneitech.com is that there is a wide range of diverse products that you can purchase. For example, there are three different application types that you can choose from which include the Industrial Type, Advanced Type, and Civil Type. Similarly, there is a range of different sizes that you can choose from. There are 11 different sizes that you can buy, ranging from the smallest 3.5-inch display to the large 15.1-inch one. The same goes for the Android series which where you can choose between 4.5-inch and 31.5-inch displays.

This is probably the biggest advantage that you can get when working with manufacturers from China. It can even be assumed that this is probably the biggest reason why the Asian country is at the forefront of the mass manufacturing business.

When you are going to be ordering in bulk, you need to save up on costs as much as you can. The more you save up, the more profit you can make when reselling. Furthermore, lower costs can allow you to set lower prices when selling. This can attract more customers and your sales can increase.

In the initial period of your business, you want to build trust with your customers and give them more value than they expect. The best way you can achieve this is by making your products available for less than the average price. And this can only be done if you are saving up on costs yourself.

The same applies to LCD displays. When you save up on costs when buying LCD displays, you can set a lower price for the whole machine or gadget that you are producing.

This is a very useful benefit for small start-up companies. Generally, manufacturers in the USA are not going to be very willing to work with you unless you are a big company or unless you have a large recognition and following. Due to this, smaller companies can have trouble getting their demands heard. However, the refusal of suppliers to do so is not unjustified. Smaller companies are going to start off with smaller orders. Small orders are not very lucrative and beneficial for suppliers. The larger the order, the more convenient it will be for the manufacturer.

However, with Chinese manufacturers, this problem is minimized. The Chinese often don’t care how big a brand you are and what recognition your company has. As long as you meet the minimum order requirements, you can get your products easily. This is highly advantageous for smaller companies. Due to this, smaller firms can get started and kick off their business.

When it comes to LCD modules, the orders are not received by the hundreds or thousands as is the case with other smaller products such as handbags and wallets etcetera. One module can cost around $250, and it is for this reason that the dynamics are a little different with this business. That is why STONE offers single pieces for sale as well as multiple pieces. This encourages smaller businesses to make their purchases since they can easily purchase as many modules as they like. As long as you meet the limit stated by the supplier, you are good to go.

Typically, when you are paying less, you can have the expectation that the quality might not be good or the time taken may be too long. However, when you are buying from the Chinese, you don’t have to face any of these problems. While you are paying less, you can get satisfactory quality and even the production time is cut down.

The factories in China have more machines and workers working simultaneously. This means that you can get bigger orders more quickly. For example, if you are getting 10 units from a domestic supplier in 4 days, you will be able to get 12 units from a Chinese supplier in just 3 days. That means that the production rate is increased, and the time taken is also cut short. This is merely an example to show that both aspects of production are enhanced when you do business with the Chinese.

Another great benefit of getting production done in China is the option for expansion. What that means is that while you can transport your merchandise to your home country, you also have the option of making them available in China. Instead of only bringing the goods back home to resell, you can set up a business that makes your merchandise available for sale in China as well.

In the case of LCD modules, this benefit relates to a reselling business. For example, if you are planning on buying some modules to use in your machines etcetera, then there is not a very suitable opportunity for you to expand. If you want to start a business in another country, you will have to open a manufacturing unit there so that your products can be produced and then get sold. Or, you will have to transport your final products to the other country in order to run your business.

However, if you are buying the LCD modules to resale at a profit, you can use the Chinese markets to grow your business. You can buy the modules at a reduced price and then sell them at a profit in a different area or city where the people will be willing to pay more.

Now that we have seen the benefits of choosing Chinese manufacturers for LCD modules, let us narrow it down a bit and look at why you should choose STONE specifically.

With STONE, you get the option of buying a range of different-sized modules. If your business deals in making different electronics and machines that require panels of different sizes, you don’t have to look at multiple suppliers to fulfill your need. You could be making some products that require 3.5-inch panels, while some of your machines could be needing 15.1-inch modules. Instead of taking the trouble to go to different suppliers, you can enjoy an all-in-one experience from STONE.

STONE offers its customers ease when it comes to making a purchase. Generally, wholesalers and suppliers sell their merchandise in bundles of 10, 50, 100, etc. However, the STONE store gives you the option of buying single pieces so that you can buy as much as you presently need.

One of the main things that you have to look at in any supplier is the level of reliability and trust. This is usually determined by the level of experience and the time that the supplier has spent in the market. STONE was founded in 2010 and has been producing LCD modules for the past 10 years.

If you are looking to buy LCD modules in bulk, look no further than the Middle Kingdom. China has become the hub of mass manufacturing and is the favorite spot for wholesalers and business owners.

In case you need some convincing about buying from the Chinese, we have compiled a list of benefits that you can enjoy when looking for TFT LCD manufacturers in China.

Responsible for performing installations and repairs (motors, starters, fuses, electrical power to machine etc.) for industrial equipment and machines in order to support the achievement of Nelson-Miller’s business goals and objectives:

• Provide electrical emergency/unscheduled diagnostics, repairs of production equipment during production and performs scheduled electrical maintenance repairs of production equipment during machine service.

Advantages: thin body and space saving. Compared with the more bulky CRT display, the liquid crystal display only needs one third of the space of the former; it saves electricity and does not produce high temperature. It is a low power consumption product, which can be achieved compared to CRT displays. No heat at all; no radiation, which is good for health, and the liquid crystal display is completely free of radiation.

The screen is soft and does not hurt the eyes. Unlike CRT technology, the LCD screen will not flicker, which can reduce the damage of the display to the eyes and make the eyes less fatigued.

Disadvantages: The visual deflection angle is small; it is easy to cause image tailing phenomenon (such as the rapid shaking of the mouse pointer). This is because the ordinary LCD screen is mostly 60Hz (60 frames per second), but this problem mainly occurs when the LCD is just popular The brightness and contrast of the LCD monitor is not very good.

LCD "dead pixels" problem; life is limited; when the resolution is lower than the default resolution of the monitor, the picture will be blurred; when the resolution is greater than the default resolution of the monitor (mandatory setting by software is required), the color of the details Will be lost.

Advantages: OLED is a self-luminous material, no backlight is required, at the same time, wide viewing angle, uniform picture quality, fast response speed, easier colorization, light emission can be achieved with a simple driving circuit, simple manufacturing process, and flexible The panel conforms to the principle of lightness, thinness and shortness, and its application range belongs to small and medium size panels.

Disadvantages: It is difficult to increase the size. In order to maintain the brightness of the entire panel, it is necessary to increase the brightness of each Pixel and increase the operating current, which will reduce the life of the OLED Device. Current Drive control is not easy. The manufacturing process is more complicated and the variability of TFT is higher.

So you’ve just bought an LCD screen and want to know what the benefits are? In this article, we’ll break it down and list some of the more common advantages of using such a monitor.

The LCD display screen is a type of electronic display device that uses liquid crystal molecules to produce images on a screen. LCD displays are thinner and more energy-efficient than their CRT counterparts, making them more popular for computers, phones, and other portable devices. Additionally, they have a longer life span and can be used in harsher environments than CRT displays.

LCD displays are known for their bright colors, sharp images, and long life spans. They also offer a great viewing experience in both indoor and outdoor environments. Below are some of the benefits that LCD displays offer:

1) Bright Colors – LCD displays produce vibrant colors that are perfect for viewing photos and videos. This makes them ideal for use in outdoor environments where sunlight is abundant.

2) Sharp Images – The pixels on an LCD display are small compared to other types of screens, which means that images appear more detailed and sharp. This is especially beneficial when viewing photos and videos.

3) Long Life Spans – Unlike other types of screens displays, which can start to show signs of wear and tear after a few years, an LCD display can last for several decades without showing any signs of deterioration.

If you are looking for a screen that offers great image quality and is highly durable, an LCD display screen might be the perfect choice for you. Not only do LCD displays offer better picture quality than other types of screens, but they also tend to last longer and resist scratches and other damage better. If you are in the market for a new monitor or laptop screen, make sure to consider Aiwa LCD display screens – they are definitely worth your consideration!

Do you know lcd display advantages ? The appearance of the LCD liquid crystal display can be traced back a long time ago. At the end of the 19th century, Austrian botanists discovered liquid crystals. Subsequently, British scientists used the electro-optical effect of liquid crystals to create the first LCD liquid crystal display. Nowadays, LCD screens are used in video surveillance (security) for more than 50%, and they are widely used in public services, transportation, energy resources, finance, and other industries. The following Proculus will introduce you to the five advantages of the LCD display module.

LCD Display includes lcd android and uart lcd display. The display principle of the lcd monitor module is to realize the restoration of the picture by twisting the deflection angle of the liquid crystal molecules in the liquid crystal pixel. The LCD liquid crystal display does not have internal ultra-high voltage components like CRT, so there will be no X-ray excess due to high pressure. Moreover, the structure and circuit of the machine screen are simple. Modularization and high integration of the chip are sufficient to minimize the electromagnetic radiation generated when the circuit is working. This design directly reduces the power consumption and heat generation of the circuit. Although the liquid crystal display module may produce slight electromagnetic radiation when it is working, this problem can be solved by shielding the circuit. As the CRT display screen considers heat dissipation, it is not allowed to drill holes in the shielding cover to cause radiation leakage.

It is the appearance of the liquid crystal display module that made the invention of the portable computer possible. Similarly, although desktop LCD screens are larger in size and weight than laptop computers, they are insignificant compared to bulky and heavy CRT screens. Compared with a 15-inch display screen, the depth of a CRT display screen is generally close to 50 cm. With the changes in consumer opinions and living environment, people have higher and higher requirements for the volume and weight of household electric screen products. The LCD display module has become the most likely display device to break the monopoly of CRT display due to its inherent advantages of slimness and lightness.

The LCD display module adopts the direct digital addressing display mode. It can directly correspond to the video signal on the screen one by one according to the address signal in the signal level after AD conversion of the video signal output by the graphics card. Displayed on the liquid crystal pixels. The CRT display screen relies on the electromagnetic field generated by the deflection coil to control the periodic scanning of the electron beam on the screen to achieve the purpose of displaying images. Since the trajectory of the electron beam is easily affected by the environmental magnetic field or geomagnetism, it is impossible to perform absolute positioning on the screen. So you know that CRT display screens are prone to geometric distortion, linear distortion, and other problems that cannot be completely solved. The LCD screen can perfectly present the picture on the screen without any geometric distortion or linear distortion.

The picture is stable without flickering. The unique display principle of the liquid crystal display determines that each pixel on the screen emits uniformly, and the red, green, and blue pixels are closely arranged. The video signal is directly sent to the back of the pixel to drive the pixel to emit light, so there will be no inherent characteristics of the traditional CRT display. Convergence and poor focus. Therefore, the text display effect on the LCD screen is quite different from the traditional CRT screen. The font of the LCD screen is very sharp, and there is no such phenomenon as the blurring of the font and the font color when the CRT screen displays the text. Moreover, since the LCD display module always emits light after power-on, the backlight works at high frequency, and the display screen is stable without flickering, which is beneficial to use the computer for a long time. The CRT display screen relies on the electron beam to repeatedly hit the phosphor to achieve light, which will cause the brightness to flicker periodically. It is easy to cause eye discomfort after prolonged use.

The direct addressing display mode of the LCD screen makes the screen adjustment of the LCD screen easier. There is no need for too much geometric adjustment, linear adjustment, and position adjustment of the display content. The LCD screen can automatically adjust the screen to the best position after the chip calculation is very convenient. You only need to press the "AUTO" button to complete this step. The cumbersome adjustment of the CRT display screen is eliminated. You only need to manually adjust the brightness and contrast of the screen to make the screen work in the best condition.

This is maybe the biggest benefit that working with Chinese LCD module manufacturers. It can even be assumed that this is maybe the biggest reason why the Asian country is at the forefront of the mass manufacturing business.

When you are will order bulk products, you need to save your money as much as you can. The more you save up, the more profit you can make when reselling. Furthermore, lower costs can help you to set lower prices in your market. This can attract more clients and explore your market.

This is applies to LCD modules market, when you save up on costs when buying LCD modules, you can set a lower price for the whole machine or gadget that you are producing. Rjoytek can provide full solutions of LCD, and with a own factory, thire products includes small inch lcd module to large size, and customized is welcome.

This is a very helpful benefit for small start-up companies. Usually, manufacturers in the USA or any other country are not like working with you if you are a small company. Due to this, smaller companies always meet trouble when they. Smaller companies are going to start off with smaller orders. Small orders are not very lucrative and beneficial for suppliers. The larger the order, the more convenient it will be for the manufacturer.

There are large production market and many factory in China, some factories have large amount of stock products, when you are buying from the Chinese, you don’t have to face any of delivery problems. Even you are paying less and buy less products, you can get satisfactory quality and fast delivery time.

Another great benefit of getting production done in China is the option is flexible, you even can get your customized products with small quantity, and you could choose sell it on your country or sell it in China, What that means is that while you can transport your merchandise to your home country, you also have the option of making them available in China.

In the case of LCD modules, LCD display is easy to break and international shipping cost usually expensive, especially shipping so far from china to your country, so if you have a Chinese company, that is good idea.  if you are buying the LCD modules to resale at a profit, you can use the Chinese markets to grow your business.

Because every point on the TFT LCD screen maintains that color and brightness after receiving the signal, it glows at a constant rate, rather than constantly refreshing the bright spots as the cathode ray tube display (CRT) does. As a result, the TFT LCD is of high quality and does not flicker, reducing eye fatigue to a very low level.

For displays of the same size, the visual area of the TFT LCD screen is larger. The visible area of the TFT LCD is the same as its diagonal size. Cathode ray tube display screen picture tube front panel around an inch or so of the border can not be used for display.

The original LCD screen is usually used in electronic watches and calculators because it is unable to display delicate characters. With the continuous development and progress of liquid crystal display technology, character display begins to be exquisite, but also supports the basic color display, and gradually used in liquid crystal TV, camera liquid crystal display.

The subsequent DSTN and TFT were widely made into liquid crystal display devices in computers, and DSTN LCD screens were used in early notebooks. TFT is used not only on laptops (most laptops now use TFT displays), but also on mainstream desktop displays.

The display material of the traditional display screen is phosphor, which is shown by the impact of the electron beam on the phosphor. The electron beam produces strong electromagnetic radiation in the moment it hits the phosphor. Although there are many display products in dealing with the radiation problem more effectively, as far as possible to reduce the amount of radiation to a very low, but to completely eliminate it is difficult. Relatively speaking, the TFT LCD screen has an innate advantage in preventing radiation because it does not exist at all.

In the aspect of electromagnetic wave prevention, TFT LCD screen also has its own unique advantages. It uses strict sealing technology to seal a small number of electromagnetic waves from the driving circuit in the display, while ordinary displays in order to emit heat. The internal circuit must be in contact with the air as much as possible so that the electromagnetic waves generated by the internal circuit "leak" outward in large quantities.

TFT LCD screens are digital and do not use analog interfaces like cathode ray tube color displays. In other words, with the TFT LCD, the graphics card no longer needs to convert the digital signal into an analog signal and output it as usual. In theory, this would make the color more accurate and perfect.

A traditional cathode ray tube display is always dragged behind a bulky ray tube. The TFT LCD breaks through this limit and gives a whole new feel. The traditional display screen emits electron beam to the screen, so the neck of the picture tube can not be very short, when the screen increases, it is necessary to increase the size of the whole display.

On the other hand, the TFT LCD screen controls the liquid crystal molecular state through the electrode on the display screen to achieve the display purpose. Even if the screen is enlarged, its volume will not increase in direct proportion, and its weight is much lighter than the traditional display with the same display area.

Compared with the traditional display screen, the TFT LCD screen starts with a pure flat glass panel, and its display effect is flat at right angles, giving people a refreshing feeling. And it is easier for LCD to achieve high resolution on a small screen. For example, a 17-inch LCD can achieve a good resolution of 1280 × 1024. On the other hand, the effect of using a resolution of more than 1280 × 1024 on an 18-inch CRT color display is not entirely satisfactory.

The traditional display screen is composed of many circuits. When these circuits drive the cathode ray picture tube, they need to consume a lot of power, and with the continuous increase of the volume, the power consumed by the internal circuit will certainly increase. In contrast, the power consumption of TFT LCD is mainly consumed by its internal electrode and driver IC, so the power consumption is much smaller than that of traditional display.

The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

According to some industry expert, the ratio of global LCD to CRT production is roughly about 6:4. LCD monitors, in the past, had some defeats in certain aspects, such as brightness, contrast, visual angle, response time, lifespan and production. Along with the technical improvement, current LCD monitors are better performed in color, brightness, contrast, nearly 180-degree visual angle and response time. Plus, it has advantages in thin design, environmental friendly, and energy-saved (because of lead in the components of CRT monitors). LCD monitors have gradually replaced the CRT.

Many users might confuse LCD monitors with LCD display or LCD TV. However, the basic requirements for LCD monitors are quite different from them. For one LCD monitor, it is usually required to have higher standards on visual angle, brightness and contrast, color display ability, response time, resolution and the stability to operate continuously 24/7. Therefore, the safe electric performance and good heat emission design should be taken into the consideration for the design of one LCD monitor.

For one LCD monitor, a much broader visual angle and higher brightness and contrast are required for watching the fixed video picture at long distances. For PC display, the ideal pictures can be showed if it meets the required brightness and contrast of 200 cd/m2 and 300:1 respectively. But for monitors, the brightness and contrast should be not less than 300 cd/m2 and 450:1. The quality of picture is not only related to the brightness and contrast but also the definition, color reducibility, and SNR (signal to noise ratio) specifications. In addition, the response time is also quite important for LCD monitors. Manufacturers recently have taken a lot of efforts on increasing the response speed from the early 60 ms, 30 ms and 25 ms to current 16 ms, 12 ms and 8 ms; the tailing phenomenon has been almost disappeared and has little difference with response time for CRT.

One of Satow"s latest launch--42" Color LCD monitor, ML-4200TM1. It features 3-dimension image processing to reduce the noise and avoid the interference from the bright, making the picture display more sophisticated with PAL/NTSC. Its unique DNX technology makes the image more stable while displaying the moving pictures and video. The resolution is about 1920 x 1080; brightness is 500 cd/m2 and the contrast ratio is 2000:1. The response time can be 6.5 ms. Power supply is AC 100-240V.

Many LCD display"s power is often DC 12 V, using the external AC power adapter 220V AC/12V DC; however, it could not meet the requirements of electromagnetism interference (EMI) and electromagnetism compatible electron agnetic compatibility (E-MC) for professional monitors working at factories. Take Stonesonic. It adopted the reliable built-in switch power instead that can meet the requirements of electromagnetism compatible and interference standard. So it ensures the constant working of the machine no matter under what kind of environments and its much more coordinated appear once design is also more convenient for project mounting and operation. Skyworth also highlights its internal power supply with low consumption, and its screen service expectancy exceeds 60,000 hours. The latest I2C controlling circuits, the high reliability of whole system.

The luminescence of LCD panel is realized through several lamp tubes (cathode vacuum tube). Because some of the tubers are fixed at the fringe of the panel, it is normal that the frame becomes heated when being used for a certain period. In the design of LCD monitors, Stonesonic applied the hydrodynamics theory to make the air whirlpool inside the space of the machine form the convection, and operate the heat emission through those metal parts inside at the same time, which all ensure the reliable and constant working of the machine. So it will not affect the lifespan of the monitor if the frame of the LCD feels a little heated by hand.

Stonesonic recently launched one 19"color LCD monitor built-in DVR--SCM-1980MR. It is one kind of 8-channel monitoring and recording all-in-one monitor, adopting top-quality 19" TFT LCD panel and has functions of 4-8 channels composite video simultaneous input, real-time monitoring and recording, network remote monitoring, recording backup and alarm pan/tilt controlling.

Satow Eletronic also has one 17" LCD with built-in 4-channel MPEG-4 DVR system-BL-1700T4/CP-5714CB. Adopting the latest DSP hardware compression for each channel, the resolution is quite high. It can remote monitor via network, viewing with IE Browser or client-end software. For the LCD monitor, its contrast ratio is 800:1, brightness ratio of 300 cd/m2, display color in 16.2 M.

Stonesonic and Skywor th also developed their latest products of LCD combination panel wall. For Stonesonic, its LCD combination panel wall has already been registered and approved for six patents. The hardware basic is FPG A array, using parallel high speed image processing technology. It implements multiple high speed video signal"s unify processing technology. It totally replaces the insert card combination controller and solves the problem of quantity limitation of VGA input. It possesses all the excellent DID display technology, embedded hardware combination technology, multiple image processing technology, signal switching technology. This advanced LCD combination panel wall display system has benefits of high brightness and high definition, low power consumption and long lifespan.

Stonesonic monitor is used in many different applications such as security, broadcast, industry and multi-media. Their application in security accounts for 60 to 70 percent. Its strengths are high definition in image quality; more natural color in display. Its LCD export accounts for 50 percent of their total market. Till now, Stonesonic has had sales points in over 80 countries. It targets more at European and US markets. The latest products also includes one big IP screen monitor; very easy to install within one single IP cable. It also differentiated others in self-developed chipsets for monitors. Other vendors might adopt AV chips for LCD monitor so the 3D image may be worse in quality.

LED electronic screen is also known as LED electronic display screen. It is composed of LED dot matrix and led PC panel, through the red, blue, white, green LED lights on and off to show text, pictures, animation, video, content. Can make different conditioning according to the needs of different occasions, such as the usual billboard activities of calligraphy and painting, is through flash to create an animation, save in a memory card of the display screen, and then through the skill method to show, can be changed at any time according to different needs, each part of the components are modular construction of the display equipment. Traditional LED electronic screen is usually composed of display module, control system and power supply system.

1. Active brightness conditioning has the function of active brightness conditioning, which can achieve the best playback effect in different brightness environments.

2. The brightness is strong. When the sunlight is directly on the surface of the screen within the visual interval, the display content is clear and visible.

11. All weather operation, get used to all kinds of harsh environment in the field, waterproof, moisture-proof, anti-corrosion, lightning protection, anti-seismic, all-round function, good display function, high cost performance, pixel tube can choose p10mm, P16mm and other standards.

LCD splicing screen can be any combination: it can select large screen splicing or small screen splicing; it can display single screen or whole screen splicing. Be able to select the appropriate splicing method and the best product according to the application requirements and system planning of the LCD splicing screen system put forward by customers, and according to the practical application environment, plan the personalized plan, and satisfy the needs of customers.

High brightness and high contrast: did LCD splicing screen has higher brightness, which is different from TV and PC LCD screen  the brightness of TV or PC LCD screen is usually only 250 ~ 300cd / m2, while the brightness of did LCD screen can reach more than 700cd / m2. The contrast ratio of did LCD panel is 1200:1, even 10000:1, which is more than twice as high as that of traditional PC or TV LCD panel and three times as high as that of back projection.

2. The brightness is even, the impression is stable and does not shine. Because every point of LCD always adheres to that color and brightness after receiving the signal, unlike CRT, which needs to constantly rewrite pixel points. As a result, the brightness of LCD is uniform, the image quality is high, and there is absolutely no flicker.

3. Thanks to the professional development of color calibration skills for did products, through this skill, in addition to the color calibration of stop screen, it can also calibrate the color of dynamic screen. Only in this way can we ensure the accuracy and stability of the picture output. In terms of color saturation, didlcd can achieve 80% – 92% high color saturation, but now the color saturation of CRT is only about 50%.

4. 120Hz frequency doubling rewriting frequency, the 120Hz frequency doubling LCD display skill of did products can effectively deal with the trailing and ambiguity in the process of rapid movement of pictures, enhance the clarity and contrast of pictures, make the picture clearer and clearer, and human eyes are not easy to get tired after long-term viewing.

6. The visual viewpoint is wider. Using this skill, the visual viewpoint can reach double 180 degrees (horizontal and vertical). Through the application of PVA skill, namely “drawing straight adjustment skill”, the LCD splicing screen has a wider visual viewpoint.

7. Ultra thin narrow edge planning, LCD splicing screen not only has the characteristics of super large display area, but also has the advantages of ultra light and thin. It can be easily assembled and installed. The special LCD panel for splicing has excellent narrow edge planning, which makes the edge of a single panel even less than 1 cm. Such a small edge effect will not affect the overall display function of all the displays.

8. High service life, the service life of the backlight of didlcd LCD screen can reach more than 50000-100000 hours  which ensures the consistency of brightness, contrast and chroma of each LCD screen used for splicing display screen after long-term use  and ensures that the service life of the display screen is not less than 50000 hours.

9. The reliability is very good. The LCD screen is usually designed for TV and PC display, which does not support continuous use day and night. ID LCD screen is used in 7×24 hours for monitoring base and display base planning support.

China"s first 8.5-generation TFT-LCD production line was launched in Bengbu, East China"s Anhui province, on June 18, 2019, representing a breakthrough in the production of high-definition LCD screen, Science and Technology Daily reported.

TFT-LCD, or Thin Film Transistor Liquid Crystal Display, is key strategic material of the electronic information display industry. The Gen 8.5 TFT-LCD production line, launched by the Bengbu Glass Industry Design and Research Institute of the China National Building Material Group, will produce high-definition LCD screens of 55 inches, the report said.

According to the Liquid Crystal Branch of the China Optics and Optoelectronics Manufactures Association, the demand for TFT-LCD in the Chinese mainland was about 260 million square meters in 2018, including 233 million square meters" Gen 8.5 TFT-LCD. However, the annual supply of domestically made TFT-LCD is less than 40 million square meters, with all of them Gen 6 or below, which cannot meet the demand in scale and quantity.

The association predicted that China"s market demand for Gen 8.5 TFT-LCD or above will exceed 300 million square meters by 2020, accounting for 49.6 percent of the total global demand.

The production and control precision of Gen 8.5 TFT-LCD is comparable to that of the semiconductor industry, representing a higher level of large-scale manufacturing of modern glass industry.

The institute in Bengbu, with 60 years of expertise in glass, has finally made a breakthrough in the production of Gen 8.5 TFT-LCD, and will provide key raw material guarantee for China"s LCD panel industry after it goes into mass production in September, the report said.

► When the leading Korean players Samsung Display and LG Display exit LCD production, BOE will be the most significant player in the LCD market. Though OLED can replace the LCD, it will take years for it to be fully replaced.

When mainstream consumer electronics brands choose their device panels, the top three choices are Samsung Display, LG Display (LGD) and BOE (000725:SZ) – the first two from Korea and the third from China. From liquid-crystal displays (LCD) to active-matrix organic light-emitting diode (AMOLED), display panel technology has been upgrading with bigger screen products.

From the early 1990s, LCDs appeared and replaced cathode-ray tube (CRT) screens, which enabled lighter and thinner display devices. Japanese electronics companies like JDI pioneered the panel technology upgrade while Samsung Display and LGD were nobodies in the field. Every technology upgrade or revolution is a chance for new players to disrupt the old paradigm.

The landscape was changed in 2001 when Korean players firstly made a breakthrough in the Gen 5 panel technology – the later the generation, the bigger the panel size. A large panel size allows display manufacturers to cut more display screens from one panel and create bigger-screen products. "The bigger the better" is a motto for panel makers as the cost can be controlled better and they can offer bigger-size products to satisfy the burgeoning middle-class" needs.

LCD panel makers have been striving to realize bigger-size products in the past four decades. The technology breakthrough of Gen 5 in 2002 made big-screen LCD TV available and it sent Samsung Display and LGD to the front row, squeezing the market share of Japanese panel makers.

The throne chair of LCD passed from Japanese companies to Korean enterprises – and now Chinese players are clinching it, replacing the Koreans. After twenty years of development, Chinese panel makers have mastered LCD panel technology and actively engage in large panel R&D projects. Mass production created a supply surplus that led to drops in LCD price. In May 2020, Samsung Display announced that it would shut down all LCD fabs in China and Korea but concentrate on quantum dot LCD (Samsung calls it QLED) production; LGD stated that it would close LCD TV panel fabs in Korea and focus on organic LED (OLED). Their retreats left BOE and China Stars to digest the LCD market share.

Consumer preference has been changing during the Korean fab"s recession: Bigger-or-not is fine but better image quality ranks first. While LCD needs the backlight to show colors and substrates for the liquid crystal layer, OLED enables lighter and flexible screens (curvy or foldable), higher resolution and improved color display. It itself can emit lights – no backlight or liquid layer is needed. With the above advantages, OLED has been replacing the less-profitable LCD screens.

Samsung Display has been the major screen supplier for high-end consumer electronics, like its own flagship cell phone products and Apple"s iPhone series. LGD dominated the large OLED TV market as it is the one that handles large-size OLED mass production. To further understand Korean panel makers" monopolizing position, it is worth mentioning fine metal mask (FMM), a critical part of the OLED RGB evaporation process – a process in OLED mass production that significantly affects the yield rate.

Prior to 2018, Samsung Display and DNP"s monopolistic supply contract prevented other panel fabs from acquiring quality FMM products as DNP bonded with Hitachi Metal, the "only" FMM material provider choice for OLED makers. After the contract expired, panel makers like BOE could purchase FFM from DNP for their OLED R&D and mass production. Except for FFM materials, vacuum evaporation equipment is dominated by Canon Tokki, a Japanese company. Its role in the OLED industry resembles that of ASML in the integrated circuit space. Canon Tokki"s annual production of vacuum evaporation equipment is fewer than ten and thereby limits the total production of OLED panels that rely on evaporation technology.

The shortage of equipment and scarcity of materials inspired panel fabs to explore substitute technology; they discovered that inkjet printing has the potential to be the thing to replace evaporation. Plus, evaporation could be applied to QLED panels as quantum dots are difficult to be vaporized. Inkjet printing prints materials (liquefied organic gas or quantum dots) to substrates, saving materials and breaking free from FMM"s size restriction. With the new tech, large-size OLED panels can theoretically be recognized with improved yield rate and cost-efficiency. However, the tech is at an early stage when inkjet printing precision could not meet panel manufacturers" requirements.

Presently, Chinese panel fabs are investing heavily in OLED production while betting on QLED. BOE has four Gen 6 OLED product lines, four Gen 8.5 and one Gen 10.5 LCD lines; China Star, controlled by the major appliance titan TCL, has invested two Gen 6 OLED fabs and four large-size LCD product lines.

Remembering the last "regime change" that occurred in 2005 when Korean fabs overtook Japanese" place in the LCD market, the new phase of panel technology changed the outlook of the industry. Now, OLED or QLED could mark the perfect time for us to expect landscape change.

After Samsung Display and LGD ceding from LCD TV productions, the vacant market share will be digested by BOE, China Star and other LCD makers. Indeed, OLED and QLED have the potential to take over the LCD market in the future, but the process may take more than a decade. Korean companies took ten years from panel fab"s research on OLED to mass production of small- and medium-size OLED electronics. Yet, LCD screen cell phones are still available in the market.

LCD will not disappear until OLED/QLED"s cost control can compete with it. The low- to middle-end panel market still prefers cheap LCD devices and consumers are satisfied with LCD products – thicker but cheaper. BOE has been the largest TV panel maker since 2019. As estimated by Informa, BOE and China Star will hold a duopoly on the flat panel display market.

BOE"s performance seems to have ridden on a roller coaster ride in the past several years. Large-size panel mass production like Gen 8.5 and Gen 10.5 fabs helped BOE recognize the first place in production volume. On the other side, expanded large-size panel factories and expenses of OLED product lines are costly: BOE planned to spend CNY 176.24 billion (USD 25.92 billion) – more than Tibet"s 2019 GDP CNY 169.78 billion – on Chengdu and Mianyang"s Gen 6 AMOLED lines and Hefei and Wuhan"s Gen 10.5 LCD lines.

Except for making large-size TVs, bigger panels can cut out more display screens for smaller devices like laptops and cell phones, which are more profitable than TV products. On its first-half earnings concall, BOE said that it is shifting its production focus to cell phone and laptop products as they are more profitable than TV products. TV, IT and cell phone products counted for 30%, 44% and 33% of its productions respectively and the recent rising TV price may lead to an increased portion of TV products in the short term.

Except for outdoor large screens, TV is another driver that pushes panel makers to research on how to make bigger and bigger screens. A research done by CHEARI showed that Chinese TV sales dropped by 10.6% to CNY 128.2 billion from 2018 to 2019. Large-size TV sales increased as a total but the unit price decreased; high-end products like laser TV and OLED TV saw a strong growth of 131.2% and 34.1%, respectively.

Millions of young white-collars support the co-leasing business in China and breed the six-billion-dollar Ziroom, a unicorn company that provides rental and real estate management services. As apartments can be leased by single rooms instead of the whole apartment, living rooms become a public area while tenants prefer to stay in their private zones – it hints that the bedroom is too small to fit in a TV.

Besides the tier-1 cities" "disappearing living rooms," the mobile Internet gives another reason to explain the declining TV sale in China. Various streaming services and high-speed networks allow people to watch programs wherever and whenever they would like to. However, the change in life does not imply TV will disappear. For families, the living room is still a place for family members to gather and have fun. The growth of high-end TV sales also tells the "living room" economy.

The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

The general quality of Chinese CCTV monitors gets much improved. Three major Chinese monitor manufacturers are Skyworth, Stonesonic and Satow. The industry started export quite earlier compared to other security vendors in China. Now, LCD monitors, monitors for surveillance in commercial setting and LCD multiple screen combination panel wall are their main products.

According to some industry expert, the ratio of global LCD to CRT production is roughly about 6:4. LCD monitors, in the past, had some defeats in certain aspects, such as brightness, contrast, visual angle, response time, lifespan and production. Along with the technical improvement, current LCD monitors are better performed in color, brightness, contrast, nearly 180-degree visual angle and response time. Plus, it has advantages in thin design, environmental friendly, and energy-saved (because of lead in the components of CRT monitors). LCD monitors have gradually replaced the CRT.

Many users might confuse LCD monitors with LCD display or LCD TV. However, the basic requirements for LCD monitors are quite different from them. For one LCD monitor, it is usually required to have higher standards on visual angle, brightness and contrast, color display ability, response time, resolution and the stability to operate continuously 24/7. Therefore, the safe electric performance and good heat emission design should be taken into the consideration for the design of one LCD monitor.

For one LCD monitor, a much broader visual angle and higher brightness and contrast are required for watching the fixed video picture at long distances. For PC display, the ideal pictures can be showed if it meets the required brightness and contrast of 200 cd/m2 and 300:1 respectively. But for monitors, the brightness and contrast should be not less than 300 cd/m2 and 450:1. The quality of picture is not only related to the brightness and contrast but also the definition, color reducibility, and SNR (signal to noise ratio) specifications. In addition, the response time is also quite important for LCD monitors. Manufacturers recently have taken a lot of efforts on increasing the response speed from the early 60 ms, 30 ms and 25 ms to current 16 ms, 12 ms and 8 ms; the tailing phenomenon has been almost disappeared and has little difference with response time for CRT.

One of Satow"s latest launch--42" Color LCD monitor, ML-4200TM1. It features 3-dimension image processing to reduce the noise and avoid the interference from the bright, making the picture display more sophisticated with PAL/NTSC. Its unique DNX technology makes the image more stable while displaying the moving pictures and video. The resolution is about 1920 x 1080; brightness is 500 cd/m2 and the contrast ratio is 2000:1. The response time can be 6.5 ms. Power supply is AC 100-240V.

Many LCD display"s power is often DC 12 V, using the external AC power adapter 220V AC/12V DC; however, it could not meet the requirements of electromagnetism interference (EMI) and electromagnetism compatible electron agnetic compatibility (E-MC) for professional monitors working at factories. Take Stonesonic. It adopted the reliable built-in switch power instead that can meet the requirements of electromagnetism compatible and interference standard. So it ensures the constant working of the machine no matter under what kind of environments and its much more coordinated appear once design is also more convenient for project mounting and operation. Skyworth also highlights its internal power supply with low consumption, and its screen service expectancy exceeds 60,000 hours. The latest I2C controlling circuits, the high reliability of whole system.

The luminescence of LCD panel is realized through several lamp tubes (cathode vacuum tube). Because some of the tubers are fixed at the fringe of the panel, it is normal that the frame becomes heated when being used for a certain period. In the design of LCD monitors, Stonesonic applied the hydrodynamics theory to make the air whirlpool inside the space of the machine form the convection, and operate the heat emission through those metal parts inside at the same time, which all ensure the reliable and constant working of the machine. So it will not affect the lifespan of the monitor if the frame of the LCD feels a little heated by hand.

Stonesonic recently launched one 19"color LCD monitor built-in DVR--SCM-1980MR. It is one kind of 8-channel monitoring and recording all-in-one monitor, adopting top-quality 19" TFT LCD panel and has functions of 4-8 channels composite video simultaneous input, real-time monitoring and recording, network remote monitoring, recording backup and alarm pan/tilt controlling.

Satow Eletronic also has one 17" LCD with built-in 4-channel MPEG-4 DVR system-BL-1700T4/CP-5714CB. Adopting the latest DSP hardware compression for each channel, the resolution is quite high. It can remote monitor via network, viewing with IE Browser or client-end software. For the LCD monitor, its contrast ratio is 800:1, brightness ratio of 300 cd/m2, display color in 16.2 M.

Stonesonic and Skywor th also developed their latest products of LCD combination panel wall. For Stonesonic, its LCD combination panel wall has already been registered and approved for six patents. The hardware basic is FPG A array, using parallel high speed image processing technology. It implements multiple high speed video signal"s unify processing technology. It totally replaces the insert card combination controller and solves the problem of quantity limitation of VGA input. It possesses all the excellent DID display technology, embedded hardware combination technology, multiple image processing technology, signal switching technology. This advanced LCD combination panel wall display system has benefits of high brightness and high definition, low power consumption and long lifespan.

Stonesonic monitor is used in many different applications such as security, broadcast, industry and multi-media. Their application in security accounts for 60 to 70 percent. Its strengths are high definition in image quality; more natural color in display. Its LCD export accounts for 50 percent of their total market. Till now, Stonesonic has had sales points in over 80 countries. It targets more at European and US markets. The latest products also includes one big IP screen monitor; very easy to install within one single IP cable. It also differentiated others in self-developed chipsets for monitors. Other vendors might adopt AV chips for LCD monitor so the 3D image may be worse in quality.

Glass substrate with ITO electrodes. The shapes of these electrodes will determine the shapes that will appear when the LCD is switched ON. Vertical ridges etched on the surface are smooth.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directlybacklight or reflector to produce images in color or monochrome.seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the color of the backlight, and a character negative LCD will have a black background with the letters being of the same color as the backlight. Optical filters are added to white on blue LCDs to give them their characteristic appearance.

LCDs are used in a wide range of applications, including LCD televisions, computer monitors, instrument panels, aircraft cockpit displays, and indoor and outdoor signage. Small LCD screens are common in LCD projectors and portable consumer devices such as digital cameras, watches, calculators, and mobile telephones, including smartphones. LCD screens have replaced heavy, bulky and less energy-efficient cathode-ray tube (CRT) displays in nearly all applications. The phosphors used in CRTs make them vulnerable to image burn-in when a static image is displayed on a screen for a long time, e.g., the table frame for an airline flight schedule on an indoor sign. LCDs do not have this weakness, but are still susceptible to image persistence.

Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other. Without the liquid crystal between the polarizing filters, light passing through the first filter would be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid-crystal molecules is determined by the alignment at the surfaces of electrodes. In a twisted nematic (TN) device, the surface alignment directions at the two electrodes are perpendicular to each other, and so the molecules arrange themselves in a helical structure, or twist. This induces the rotation of the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted and the polarization of the incident light is not rotated as it passes through the liquid crystal layer. This light will then be mainly polarized perpendicular to the second filter, and thus be blocked and the pixel will appear black. By controlling the voltage applied across the liquid crystal layer in each pixel, light can be all
