The worlds of high-end Color LCD Modules are taken over. As our world evolved and embedded devices becoming more, and more sophisticated and prevalent, we tend to look at the art of design. Steve Jobs sums it up just right. “Design is not just what it looks like and feels like. Design is how it works.” TFT LCD modules are a type of variant of an LCD which uses thin film, appliances such as: TV, computer monitors, kindles, mobile phone, and navigation system. The construction of a color LCD module or TFT LCD is quite extraordinary because of the circuit layout process; this form of layout is similar to the layout of a semiconductor product. Even though as we observe the TFT LCD display we came across few pros and cons which are most needed for this discussion. The advantages of TFT LCD are as follows: less energy consumption, visibility is sharper in other words has superb quality, physical design, response time, and less eye strain etc… With every great product there are few disadvantages associated, such as, cost and viewing angles.
TFT LCD displays are very convenient because of the energy consumption associate with this display, knowingly in today’s society saving energy is a number one priority to reduce greenhouse gas and ensure a better future generations. Due to the construction of TFT structures Pixel like materials does not consume much energy to begin with except this material consume far less power than a comparable CRT monitor. The images of a TFT display does not rely on the scanning of electron beams instead they are free from flicker and has a crisp image, with no geometric distortion. The physical design of TFT display are space savors which can be position anywhere in ones office, or house with a rotations mechanism in place for less constrains on space.
As mention before TFT LCD has few disadvantages, due to the nature of the design TFT LCD display may cost a little more than a regular monochrome display. Other disadvantages may arise when the viewing the display at the 6 0’clock direction but in fact the optimal viewing is at the 12’oclock direction this may also lead to inversion which or common in situation like this; however TFT displays are superior and will be in production for years to come.
A monitor is a device that displays information in pictorial or other form. It could be data, text, graphics etc. Most people use it to display video games and movies on their computer screens. This article will tell you things like what is TFT monitor? What are the advantages of using one? Is there any disadvantage of using one? And so on.
A TFT monitor is a type of LCD display that is found in monitors like TVs, computer screens, and other devices. It stands for Thin Film Transistor which means that each pixel has its own transistor. This design allows the pixels to be brighter and last longer than other types of displays.
LCD monitors, also called flat panel displays are replacing the old-style cathode ray tubes (CRTs) in both televisions and computer screens. LCDs use thin film transistor technology which makes them more energy efficient than CRT video input devices while delivering equivalent image quality to previous generations of these display types – all at lower prices!
The video game industry was the fastest growing ICT industry in 2013. The monitors are also used in TVs, computers, and other devices. The biggest advantage is that they’re brighter and more durable than other types of displays so you won’t need to replace them as often!

Screen rotatable, screen ratio 16:9/4:3 adjustable, brightness, contrast and color adjustable – all these features will help you get the most out of this monitor!
TFT monitors are packed with state-of-the art technology that provides superior imaging and display. In addition to the many benefits you’ll get from the overall video image quality, there is also a wide range of features that can be used to enhance your viewing pleasure! Some of the advantages include:
TFT monitors have sophisticated video processing technology that makes images better looking, helps eliminate jittery text, provides advanced auto-adjust features for optimal image characteristics.
Nothing is perfect, but using TFT monitors at home or work will give you an overall superior video performance and world-class viewing pleasure. However if you set up multiple screens together to create a big display it might cause some problems:
If all your monitors are TFT and they’re not calibrated correctly, the colors and brightness will be off and your image quality won’t be as good as it could be.
If you used a smaller TFT screen as the primary display and others are larger than they won’t fill the whole space so part of each monitor will be cut off.
Using TFT monitors in your home or office is one of the best ways to maximize your viewing pleasure. There are many benefits including great picture quality, wide viewing angles, great energy efficiency, faster refresh rates which makes them more durable than old monitors types like CRTs.
Although it’s easy to set up multiple screens together there might be some problems if all of the screens aren’t calibrated properly and if you’re using non-standard resolutions or smaller displays on any part of your configuration. The bottom line though is that using TFT monitors give you an excellent video experience so you can enjoy your videos, TV shows, movies and the web!
TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.
TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.
There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.
In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.
The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.
Touch type and accuracy.What type of activities are you planning on using your device for? If it’s for extended outdoor use, then you should go with projected capacitive touch as this is more precise and accurate. Touch accuracy is important for industrial and commercial applications.
Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.
The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

The tried and trusted TFT is the display of choice for most industrial designs, but it does have its limitations in viewability and colour vibrancy. But what about the relatively new technology, IPS (in plane switching) which has turned the TFT into a super-TFT? What are the benefits and drawbacks of each?
IPS derives its name from the fact that the liquid-crystal molecules are aligned in parallel with the glass plates, whereas the TN principle adopted in conventional TFT displays is based on perpendicular alignment of the molecules. In an IPS display, the crystals remain oriented in parallel whether the pixel is turned on or off.
A TFT display is a form of Liquid Crystal Displaywith thin film transistors for controlling the image formation. The TFT technology works by controlling brightness in red, green and blue sub-pixels through transistors for each pixel on the screen. The pixels themselves do not produce light; instead, the screen uses a backlight for illumination. Discover our TFT Products
Because the pixels block light when in the off state (the opposite situation to conventional TFT), IPS TFT exhibits high contrast and the background is true black when the display is powered down.
Display choice really does depend on your application, end user and environment. It may be a higher-grade IPS is needed to satisfy outdoor requirements, or a lower cost standard TFT display is sufficient. Before you make your choice, why speak with us and we will be happy to talk you through your options.
TFT (Thin Film Transistor) LCD (Liquid Crystal Display) we are talking here is TN (Twisted Nematic) type TFT displays which is align with the term in the TV and computer market. Now, TFT displays have taken over the majority of low-end color display market. They have wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, consumer electronic products etc. For more information about TFT displays, please visit our knowledge base.
Talking about Pros and Cons of TFT displays, we need to clarify which display they are compared to. To some displays, TFT displays might have advantages, but compared with another display, the same character might become the disadvantages of TFT displays. We will try our best to make clear as below.
Less Energy Consumption: Compared with CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) and LED (Light Emitting Diode) display, which made laptop possible.
Excellent physical design. TFT displays are very easy to design and integrated with other components, such as resistive and capacitive touch panels (RTP, CTP, PCAP) etc.
Minimum Eye Strain: Because TFT panel itself doesn’t emit light itself like CRT, LED, VFD. The light source is LED backlight which is filtered well with the TFT glass in front for the blue light.
More Energy Consumption: Compared with monochrome displays and OLED (PMOLED and AMOLED) display, which makes TFT displays less attractive in wearable device.
Poor response time and viewing angle: Compared with IPS LCD displays, AMOLED displays and recent micro-LED display. TFT displays still need to note viewing angle of 6 o’clock or 12 o’clock in the datasheet and still have the gray scale inversion issue.
High tooling cost: Depending on which generation production line to produce and also depending on its size. Building a TFT display fab normally need billions of dollars. For a big size display which needs high generation production line to produce. The NRE cost can be millions dollars.
Sunlight Readability: Because it is very expensive to produce transflective TFT LCD displays, in order to be readable under the sunlight, very bright LED backlight (> 1,000 nits) has to be used. The power needed is high and also need to deal with heat management. If used together with touch panel, expensive optical bonding (OCA or OCR) and surface treatment (AR, AF) technologies have to be used.
Twisted nematic or TN panel, vertically aligned or VA panel, and in-plane switching or IPS panel are three broad types of thin-film-transistor liquid crystal display or TFT LCD that have become very popular screen display technologies used in an array of consumer electronic devices.
Among these three variants, IPS is a more recent LCD technology. Furthermore, the advantages of an IPS panel over a TN panel or a VA panel have made it a more popular LCD option used in modern consumer electronic devices such as smartphones and tablet computers.
Depending on the functional scope of a particular device however, a TN panel or a VA panel can have more advantage over an IPS display. This article compares and contrasts these three LCD technologies using six common display characteristics: color reproduction, viewing angle, contrast ratio, pixel response time, power consumption, and cost and price.
Poor color reproduction is one of the disadvantages of twisted nematic LCD. Therefore, one of the advantages of a VA panel and an IPS panel over a TN panel is color accuracy and better image quality due to better color reproduction.
Most VA and IPS panels have an 8-bit RGB color depth compared with the 6-bit RGB color depth of TN panels. Among the three however, IPS panel has the better color reproduction. Several IPS panel variants have featured 16-bit to 24-bit RGB color depth.
Note that a 6-bit display panel means that the red, green, and blue channels of its single pixel are capable of 64 levels, thus producing 262,144 possible colors. Meanwhile, an 8-bit display has 256 levels in each single pixel, thus producing 16.7 million possible colors.
The color reproduction advantage of VA panel has made it a popular LCD technology used in high-end computer monitors and large HD television sets. But IPS panels are becoming more popular in smartphones and tablet computers. Because of its superior color reproduction, IPS is also a favorable LCD option for color critical works such as graphic design and video editing.
Strong dependence on viewing angle is another disadvantage of twisted nematic LCD. A user needs to view a TN panel from a straight up 90-degree angle to maximize its visual performance. When viewed from other angles, colors and images on a TN panel will appear duller and darker.
However, a close comparison between a VA panel and a TN panel will reveal that the former has a better viewing angle. But most VA variants suffer from color shifting. This means that uneven brightness levels across a VA screen become noticeable when viewed from a slightly different angle.
Wide viewing angle is an advantage of an IPS panel over TN and VA panels nonetheless. High quality IPS panels produce consistent brightness and contrast levels when viewed from different angles. This is the reason why in-plane switching has become an ideal LCD technology for entertainment devices such as television sets and mid-range to high-end smartphones and tablet computers.
A narrow viewing angle provides some privacy and security however. This can be an advantage of TN panel over an IPS panel. This means that a TN panel can be an ideal LCD option for individuals or organizations that handle sensitive information in the presence of other people.
Contrast ratio is the ratio between the luminance of the brightest color and that of the darkest color. In other words, it is the difference between the brightest whites and the darkest blacks.
Low contrast ratio is another disadvantage of twisted nematic LCD technology when compared against vertical alignment and in-plane switching LCD technologies. However, between a VA panel and an IPS panel, the former has a better contrast ratio.
Backlighting can be blocked effectively in a vertical alignment LCD technology, thus producing deeper blacks and a higher contrast ratio compared to in-plane switching LCD technology.
Higher contrast ratio naturally corresponds to better display panel quality and manufacturers have banked on this to promote the superiority of their product over their competitors. Still, some argues that contrast ratios are all hype because of the absence of testing standards in the industry.
A shorter and better pixel response time is a very notable advantage of TN panel over a VA panel and an IPS panel. Both vertical alignment and in-plane switching LCD technologies inherently suffer from longer pixel response time. However, a comparison between a typical VA panel and a typical IPS panel will reveal that the former has the worse pixel response time.
The response time advantage of TN panel makes it a perfect LCD option for fast-paced gaming and hardcore gamers. Although there are VA and IPS variants that feature reduced pixel response times, these panels are more expensive than TN panels.
TN technology does not require a current to flow during operation. It also uses low operating voltages. These advantages make TN panels popular in low-powered LCDs found in portable and miniscule electronic devices such as digital watches and calculators.
Note that VA panels and IPS panels are largely popular in power-intensive devices such as computer monitors, smartphones and tablet computers, and television sets.
Among the three LCD technologies, twisted nematic LCD technology is easier to implement. This means that twisted nematic panels are inexpensive to manufacture, thereby resulting in low prices for end users.
VA panels are more expensive than TN panels. However, they are relatively inexpensive when compared against IPS panels. This is the reason why VA computer monitors and television sets were very popular before the advent of IPS panels.
Because IPS panels are more expensive among the three LCD technologies, they are usually found in mid-range to high-end consumer electronic products. But the growing popularity of in-plane switching LCD technology is currently driving down the prices of IPS panels. Some IPS units are actually considerably cheaper than high-end VA panels.
The aforementioned comparison among TN panel, VA panel, and IPS panel revealed that there is no LCD type that is better at everything. Each type of LCD technologies has its own advantages and disadvantages.
From the list above, TN panels have remained an ideal LCD option used in minuscule electronic devices such as digital watch and calculator because they are very cheap to manufacture and consumes less power. They also remain a popular computer monitor option because of their affordability and fast response time.
On the other hand, IPS panels have the best color reproduction, color accuracy, and wider viewing angle compared with TN and VA panels. These panels have been featured in mid-range and high-end consumer electronic devices such as laptops, smartphones, and tablet computers. IPS is also an ideal computer output display for color critical tasks.
VA panels are situated between TN panels and IPS panels. They are more expensive than TN but are relatively cheaper than IPS panels. They offer better color reproduction and more decent viewing angle than TN panels although these characteristics are not superior over IPS panels.
When we purchase a new smartphone we go through a list of specifications that includes the processor, software, cameras, display type, battery, etc. The display of the smartphone is something which has always been a concern for people. And smartphone technology has advanced so much in the past decade that you get several display technology options to choose from.
Today, a smartphone is not just a means to send and receive calls and texts. It has become a general necessity, so choosing the right technology should be your main priority. Coming back to displays, as we said there are plenty of display types available right now.
Two of the main contenders for display technologies that are widely available are AMOLED and LCD. Here in this article, we will be comprising AMOLED vs LCD and find out which one is better for you.
Starting with the AMOLED first, it is a part of the OLED display technology but with some more advanced features. To completely know about it must understand its all three components. The first one is LED, “Light Emitting Diode”. Then we have “O” which stands for organic and makes the OLED.
It actually means that organic material is placed with two conductors in each LED, which helps to produce the light. And the “AM” in AMOLED means Active Matrix, it has the capability to increase the quality of a pixel.
The AMOLED display is similar to the OLED in various factors like high brightness and sharpness, better battery life, colour reproduction, etc. AMOLED display also has a thin film transistor, “TFT” that is attached to each LED with a capacitor.
TFT helps to operate all the pixels in an AMOLED display. This display might have a lot of positives but there are a few negatives too let’s point both of them out.
It comes with individual LEDs so, the pixels can be turned on and off individually. This will show you true black colours, as the pixels on the black part of the image will be turned off.
A major issue with these displays is of burning of pixels. After showing a specific image or colour for a longer period of time, the pixel can get burned. And if there is a problem with a single pixel it will affect the entire display.
Low outdoor visibility, usually the AMOLED Displays are quote not bright in direct sunlight and outdoor readability could be a problem for some devices but average screen brightness.
The LCD stands for “Liquid Crystal Display”, and this display produces colours a lot differently than AMOLED. LCD display uses a dedicated backlight for the light source rather than using individual LED components.
The LCD displays function pretty simply, a series of thin films, transparent mirrors, and some white LED lights that distributes lights across the back of the display.
As we have mentioned, an LCD display always requires a backlight and also a colour filter. The backlight must have to pass through a thin film transistor matrix and a polarizer. So, when you see it, the whole screen will be lit and only a fraction of light gets through. This is the key difference comparing AMOLED vs LCD and this is what differentiates these two display technologies.
The LCD displays are cheaper compared to the AMOLED as there is only one source of light which makes it easier to produce. Most budget smartphones also use LCD displays.
LCD displays have bright whites, the backlight emits lots of light through pixels which makes it easy to read in outdoors. It also shows the “Accurate True to Life” colours, which means it has the colours that reflect the objects of the real world more accurately than others.
LCDs also offer the best viewing angle. Although it may depend on the smartphone you have. But most high-quality LCD displays support great viewing angles without any colour distortion or colour shifting.
The LCD displays can never show the deep blacks like AMOLED. Due to the single backlight, it always has to illuminate the screen making it impossible to show the deep blacks.
The LCDs are also thicker than other displays because of the backlight as it needs more volume. So, LCD smartphones are mostly thicker than AMOLED ones.
Both of these display technologies have their own Pros and Cons. Taking them aside everything ends up with the user preferences as people might have different preferences among different colours and contrast profiles. However, a few factors might help you to decide which one fits perfectly for you.
Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.
The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results.
The last thing is battery consumption, and there is no one near the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance.
Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big display OEMs, like Samsung and LG are focusing more the OLED technologies for their future projects. So, it makes sense to look out for AMOLED displays. That being said, if we see further enhancements in the LCD technology in terms of battery efficiency and more, there is no point to cancel them at this moment.
TFT stands for Thin-Film Transistor. TFT technology is a new standard these days for manufacturing displays, monitors, laptop screens, and other devices. TFT LCD displays can show crisp text, vivid colors, fast animations, and complex graphics.
TFT LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the displays of choice. Almost all LCD monitors today take advantage of the TFT technology.
Each pixel on a TFT display is backed by a tiny transistor. Transistors are so small these days, they need only a very minimal charge to control what they do. TFT displays are much more energy efficient than regular CRT screens that need a powerful light source.
TFT displays also allow for very fast re-drawing of the display, so the image has very little chance to flicker. This was not always the case with flat-panel monitors. Original passive matrix LCD displays were not able to refresh at very high rates and therefore could not keep up with fast moving images. A TFT monitor refresh rate is very high resulting in a display that can be used for video, gaming, and all forms of multimedia.
A TFT monitor delivers crisp text, vibrant colors, and an improved response time for multimedia applications. Today"s standard for response rate in TFT monitors is 16 ms or less.
In general, a LCD display comprises of a layer of LCD material and one or more polarizing layers made of plastic, glass, or some other material. A LCD display has a sandwich-like structure with liquid crystals filled between two glass (or plastic or polycarbonate) plates.
These liquid crystals when stimulated by an external electrical charge can change the properties of light passing through them. When you align two polarizing materials with each other, light passes through. When you align one polarizing agent at a 90° angle to the other, light is blocked. Change the voltage, and the amount of light passing through the display is changed.
Liquid crystals in LCD monitor act as a dynamic polarizing agent. They change their orientation when you place a voltage across an LCD cell. The orientation of the polarizing agent under the LCD layer either blocks or passes light.
A TFT display is an advanced LCD display. A TFT monitor uses so-called thin-film transistor technology to project a picture on the screen. Transistors in a TFT display are used to change the orientation of the polarizing agent.A typical 17-inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. The following text explains TFT in a greater detail...
When you look at a passive-LCD technology, the cells act as capacitors. When you charge a cell, the liquid crystal flips to one position. When you stop supplying charge to the cell, it voluntarily bleeds off its voltage and the liquid crystal slowly twists back to its original position.
Passive LCD panels cannot quickly change the orientation of the crystal. Well, it is quick, but not quick enough to display fast-moving graphics. To overcome this slowness, engineers came up with active-LCD technology. Active-LCD displays use transistors to actively change the orientation of crystals. That is where TFT comes from. T in TFT for transistor. This method allows for faster control of the LCD cell but is also more complex.
While passive-LCD displays start to blur with images moving faster than 8 to 15 frames/sec, TFT displays can display full-motion video and graphics because they use fast switching transistors.
Now that we know how a LCD works and what it behind TFT, we can start talking about color. Each pixel in a color TFT LCD is subdivided into three subpixels. One of the subpixels is capable of producing red, the other one green, and the last one blue color. Red, green, and blue are the basic colors. Any other color can be produced by mixing up these three. One set of RGB subpixels is equal to one pixel.
Old TFT displays and the small ones in simple applications such as calculators are reflective TFT. A reflective TFT display has no backlight. The polarizing agent at the rear of the TFT display is simply a mirror layer behind the TFT panel. The agent merely reflects incoming light from the front of the display. You need to be in a well-lit room to be able to read this type of display.
The next step in a TFT LCD design was to add a light source to it. More advanced TFT displays have added sidelights or front lights to these displays. Sidelights and front lights are virtually the same as backlights. The difference is just the position of the light. Front lights sit on the side or slightly in front of the TFT layers. They are designed so that the light they produce shines through the TFT panel and bounces off the reflective polarizing agent back through the display.
A transmissive TFT uses a backlight. Most TFT LCD panels today are designed with a backlight. The source of the light is mounted at the rear side of the LCD panel and shines light towards your eyes through the TFT panel"s polarizing medium (liquid crystal). Small displays, such as cell phones or calculators, use light source that is placed along the sides of the display.
The common TFT-display backlight is the CCFL (cold-cathode fluorescent lamp). CCFLs are similar to fluorescent light tubes that you commonly find in offices and homes. Their advantage is that they are small, inexpensive, replaceable, and cheap.
The polarizing medium in a TFT that transmits or blocks the backlight is clear, so any light shining on the display from the front competes with the backlight. If the light source shining on the front of the TFT display is strong enough, such as sun on a sunny day, it simply overpowers your laptop TFT display"s backlight and the display image is washed out. A reflective TFT display is usually a better choice for applications with high ambient light.
LED technology has only recently achieved the white light necessary to illuminate these panels. LEDs are the choice these days because they are stable over temperature ranges, durable, and very energy efficient. That is why if you buy a laptop with a TFT LED back-lighted display, it is possible that it will go for as much as 8 hours with your battery.
VISLCD has been engaged in LCD production and sales for 9 years, and we have met many customers who shared with us that they had encountered unreliable LCD suppliers.
For example, the answer is not what you asked for, the LCD product cannot be delivered on time, the price of the LCD suddenly increases, the LCD module suddenly breaks down during the use of the product, or even the LCD is discontinued after less than 1 year of delivery…etc. In addition, there are many customers who are not sure what type of LCD supplier they are looking for.
In view of all the above, VISLCD has written this article to share knowledge about LCD suppliers and other issues related to LCD. We believe it will be helpful to LCD customers.
To understand LCD suppliers, we first need to know what kinds of LCD suppliers are available. Then LCD customers can find the right supplier based on information such as their product applications, LCD requirements and forecast volume.
LCD original manufacturer refers to the original manufacturer of LCD panel. Originated from the USA in the 1960’s, after more than 50 years of development, the manufacturers are now mainly located in China mainland, Korea and Taiwan. Among them, the Chinese manufacturers in recent years rely on the rapid scale, technology development and price advantage, has gradually occupied the main market share.
The video below is an official video presentation of the BOE display factory and Century Display (CTC), which will give you a more visual understanding of the original LCD manufacturer.
The 5.1 generation TFT-LCD line of Century Display in Shenzhen, China, for example, has been put into operation since 2008 with a cumulative fixed investment of more than $4 billion, and the cost of water, electricity, employee wages and equipment depreciation is as high as $0.5~100 million/month. The monthly production capacity is about 100,000 sheets ( 1300*1200mm/sheet). If all of them are used to produce 7-inch LCD panels, then the monthly shipment volume is up to 9,000,000 pcs. Therefore, a very large monthly shipment volume is required to meet the normal operation of the factory.
This is only the 5.1 generation TFT-LCD line, if it is 8.5 generation line or even 10 generation line or more, then the cost and shipment volume may be several times or even ten times more. It should be noted that the number of generations of LCD lines does not mean that the technology is high or low. The higher the generation, then the larger the size of the LCD can be put into production, of course, the greater the volume of shipments and investment amount.
LCD original manufacturers generally provide mainly LCD panels, but also provide COG (LCD + IC), FOG (LCD + IC + FPCA cable) and other kinds of LCD semi-finished products. Also includes a small amount of the original LCD module. But the original LCD factory will only deal with the famous brand companies directly (such as Apple, Dell, Xiaomi, etc.), or through agents to ship. And the MOQ quantity requirement is very high (generally 1,000,000 pcs/month or more), the unit price of original LCD module is also high and the degree of customization is low.
LCD original manufacturers usually have an order MOQ requirement for their agents, which translates into an LCD unit quantity of no less than 100,000pcs/month. When the LCD demand is high, this will not be a problem; but when the market is low, the agent must buy the agreed MOQ quantity of LCD from the original LCD manufacturer even if there is no customer demand for the time being. So when the low season, if your order quantity is large enough, then you may get a very good LCD panel price from the LCD agent, which may even be lower than the agent’s purchase price.
LCD module manufacturers is to purchase LCD semi-finished products (such as LCD panel, COG or FOG) from LCD agents, then purchase ICs from IC agents, produce or purchase backlight, FPCA cable and touch screen components, and then integrate all the above components into LCD module or touch LCD module. LCD module factories vary in size from tens of millions of pcs to hundreds of thousands of pcs shipped per month.
The production mode of medium and large size module factories (15.6 inches or more) and small and medium size module factories (0.X~10.1 inches) are different.
Medium and large size module factory generally get the semi-finished products are FOG LCD (also known as open cell LCD) from the original LCD manufacturers or LCD agents, and then add the backlight assembly into the finished LCD module. The advantage of doing so is that the quality is relatively stable, but the degree of customization will be much lower. Because FOG LCD already includes FPCA cable, generally speaking, the only thing that can be customized is the brightness of the backlight and the touch panel and cover glass (if needed). The rest are difficult to change, unless the customer’s LCD demand is very large.
The small and medium size module factory after years of mature development of the industry, the degree of customization will be much more flexible. The semi-finished products are mainly LCD panels, which means that the backlight size, backlight brightness, FPCA cable design, shape and PIN number, as well as the touch panel and cover glass can all be customized according to the customer’s requirements. But the MOQ requirement is higher for the backlight size. Other parts of the customization generally require LCD MOQ of at least 2,000~5,000 pcs, which varies depending on the LCD size.
Since LCD module manufactures vary in size and quality control(especially small and medium size LCD module factories), and most of the components are sourced, the selection of module factories is particularly important if customers want to buy LCDs with good quality and competitive prices.
For example, if the factory’s customers are mostly low-cost products or repaired product manufacturers, then it can be assumed that the quality of his products is not too good, LCD panels and some other components may be B-grade products, not A, can only meet short-term use.
This is essential to ensure supply. In case of supply shortage, many module factories with insufficient upstream channels sometimes cannot even start production. Because they can not buy raw materials such as LCD panels and ICs.
As the name implies, trading companies do not have their own factories, but directly sell finished LCD products from LCD resellers or LCD modules from module manufacturers. Generally speaking, the LCD prices of trading companies are relatively high and the quality and reliability are a little weaker. However, there is no shortage of good trading companies with good quality management teams and good upstream channel resources. The biggest advantage of trading companies is their flexibility, which can meet the diversified needs of customers.
2) Shenzhen has 3 types of buildings related to lcd (including other electronic products): office buildings, factories and markets. Almost all LCD panel and IC agents are located in various office buildings in Shenzhen, while component factories such as FPCA, Touch panel and backlight are located in various industrial parks in the suburbs. It is possible to find the right components and develop new products in the shortest time. Of course, there is also the famous Huaqiang bei(north) Electronic Market, a very complex place.
VISLCD was a trading company in the early days. But after nearly 9 years of development, it has developed into a combination of LCD module factory and LCD agent. The company is located in LCD base Shenzhen, China and operates in both Hong Kong and Shenzhen. We have our own module factory and have direct relationship with Century Display, LG, HKC and other LCD original manufacturers. Our main employees are also from these LCD manufacturers.

Therefore, VISLCD is one of the best choices for medium-sized customers in terms of quality stability, semi-finished parts supply and customization.
Apple has used the Super AMOLED screen developed by Samsung since the iPhone X. If the original OLED is replaced after the warranty period of the mobile phone screen, the iPhone X and iPhone XS will cost $549. The high cost of replacing screens is not something that every consumer is willing to accept. Soft OLED and hard OLED replacement screens have gradually become hot selling products in mobile phone repair shops. Recently, the appearance of in cell LCD adapted to the iPhone X has broken this calm. It uses lower-cost LCD instead of OLED screens and enters the iPhone X repair industry with an absolute price advantage. What are the advantages and disadvantages of in cell LCD and OLED screen?
Take iFixit, a more authoritative website in the smartphone repair industry, and launched an in-cell LCD screen suitable for iPhone X / iPhone XS / iPhone XS Max. The prices are $75, $85, and $165.Its price is only half of OLED. The
In-cell LCD screen is darker than OLED, and the screen display color gamut and resolution are lower. When the mobile phone is in standby, the OLED screen can display pure black, while the LCD cannot.
The biggest advantage of the OLED screen is that the power consumption is small, the power consumption of the TFT LCD screen is larger than that of the OLED, and the standby time is shortened after the LCD screen is replaced.
In low-light environments, users who use OLED mobile phone screens are prone to eye pain. Because LCD can directly reduce the brightness of the screen, and OLED uses the method of adjusting the brightness and non-light duty cycle to deceive the brain to adjust the brightness. This means that in the dark light environment when the human pupil is naturally enlarged to allow more light to enter, the OLED actually enters the pupil at the highest brightness.
According to the iPhone customer experience feedback information, the LCD screen is more in line with the current user habits on the market. Apple is developing LCD screens for both the iPhone Xr and iPhone 11. Compared with OLED, iPhone in cell TFT LCD has a larger display effect than the original screen, and the price is much cheaper than OLED.
