lcd monitors advantages and disadvantages price
You might believe that LCD Screens originated in the early 2000s, when in fact, they were developed by an Austrian botanist, Friedrich Reinitzer, in 1888. The truth is that it took a long time to go from the creation of liquid crystals to a wide range of LCD applications. The first modern LCD was commercially produced in 1972 by the International Liquid Crystal Company, ILIXCO. The LCDs were initially used in digital wristwatches, and most people are unaware of that. Finally, between 1990 and 1997, Japan, Korea, and Taiwan developed them for larger displays. Since the technology has been widely used, it’s imperative to know theAdvantages and Disadvantages of LCD monitors and screens in today’s age.
Computer users switched to lightweight and space-efficient LCD monitors right after the technology entered the consumer market. There are several advantages of LCD over the traditional ones such as CRT. Some of the prominent ones are described below.
LCD screens consume less power because they do not need a backlight to function. This makes them an excellent choice for smartphones and tablets manufacturers, where battery life can be a major concern. LCDs do not require the high voltage backlighting required by other technologies like plasma, LED, or CRT Monitors. This is also great for businesses looking to save money on manufacturing and reducing greenhouse gas emissions created when fossil fuels are burned in electricity production. LCD Screens can also use fluorescent lighting, which saves even more energy.
LCDs are known for their high-definition display. They can produce a very clear, crisp image if they have an HD resolution screen. The advantages of having a high-definition display are many, but the biggest is that it allows you to see details in pictures and images with greater ease. This technology would be best for graphic designers or photographers because they need to have every detail displayed clearly to do their job properly.
The picture difference is also noticeable when watching movies or playing video games. It can even reduce eyestrain if you work on your computer for long periods each day because LCDs have a flicker-free display, so there isn’t any screen flickering, which sometimes causes eye fatigue.
LCD screens have very high contrast ratios when compared to other display technologies. That means the blacks are deeper and richer than many other visual displays, leading to more vibrant colors overall. This is especially useful for photos or videos that need rich color to look their best. It’s really helpful if you’re an artist who wants your work displayed with vivid detail because it enhances realism in art pieces. The higher contrasts also make details easier to see, so they can help reduce eyestrain during computer use since there is less glare on the screen from intense lighting sources nearby due to darker black levels.
LCD screens don’t suffer from the same image retention problems that plasma TVs do. This means that if you leave something static on the screen for too long, it won’t be burnt into your television’s display like a ghost would linger in the corner of your computer monitor. It is especially useful to gamers or people who watch movies and TV shows with subtitles because there won’t be any distracting shadows created by text sitting on top of already displayed content. You can also play games for longer periods without worrying about the damaged screen because there is no phosphor involved in creating images on an LCD panel.
LCD panels are very lightweight compared to other display technology types, which means that they can weigh less than 15 pounds. This makes them easy to transport from place to place for presentations or showing off your displays at a trade show booth. The list of advantages of LCD monitors doesn’t stop there, though; imagine being able to have multiple monitors without having bulky equipment taking up all the space in your office. That’s right; since LCD screens only need one cable connection to connect to a power source, and you won’t have any issues with tangled cords making things look messy during business hours.
LCDs or Liquid Crystal Displays have longer shelf lives. That is why despite being costlier than the older CRT technology, people try LCDs because they are cheaper in the long run as they tend to last 13000 to 14000 hours more. Typically, an LCD can have a life span of 60000 hours on average. But with proper care and stable electricity flow, they more so than not tend to last longer. Roughly, it all translates into the fact that an LCD can last nearly two decades if used with care.
LCDs offer several benefits over CRT and plasma display technologies. However, they also have some disadvantages that may make them less suitable for certain applications or undesirable in some situations.
The main reason why LCD screens tend to be more expensive than other displays like CRTs or OLEDs is that they require backlighting since there isn’t anything illuminating the pixels from behind, so manufacturers need multiple layers with different material compositions, which makes it difficult and costly to manufacture these types of displays. Obviously, developing larger displays takes effort, money, and time; the bigger the picture, the more expensive it is to buy.
When the backlight brightness is turned up, ghosting and blurring can occur. This is a problem because users need to see details clearly to work or play games with high-performance standards. Displays that have “power-saving” features will show fewer problems when they’re at higher brightness levels, but it’s still an issue for people who want optimal performance from their displays. Also, the picture performance is compromised in the absence of light in the area where the screen is placed.
When an LCD screen is viewed under bright light, the pixels are lit by phosphors. However, when a light source is destroyed, the LCD no longer produces an image on the display because it requires additional light sources to illuminate the pixels.
LCDs are less reliable than other types of monitors, especially when it comes to the number of hours they can be used before failing. Displays that have been around for a few years will need more frequent repairs and replacements because their internal components wear out with time. Displays used often will also need to be repaired more frequently than those that aren’t, especially if they’re damaged by mishandling. Displays can fail for several reasons, including dead pixels and backlight failures.
While LCD screens do have some advantages over other TV types, they also have disadvantages that may make them less desirable for your needs. This can be especially true if you want a large display with the best possible picture quality. LCDs are different from plasma TVs and OLED displays in image quality, motion handling, and input lag. The screens also differ in power consumption, resolution signal-scaling on PC monitors or HDTVs with 720p inputs, viewing angle limitations compared to OLED/plasma technologies, and contrast ratio issues. Since Plasma and OLED displays outperform LCD, users are more likely to opt for them.
LCD Displays have inferior viewing angles compared to Plasma and OLED Displays. This means that as you move from side to side or up and down, the image quality diminishes on LCD Displays. In other words, if you’re not sitting directly in front of an LCD TV at a proper seating distance for your room size, some parts of the picture will appear washed out. This is different from plasma TVs because they have better off-angle color reproduction, making them suitable for those who plan to watch with a group of people where everyone can’t sit right in front – even if they are large displays.
While LCDs are great for viewing, they do require an additional source of light for standard performance. Why do you ask? Because LCDs have a poorer black level. The technology cannot create dark or deep gray shades, compromising the user experience. Hence, you should place the display at perfect viewing angles to enjoy uninterrupted services.
Everything from TV�s to monitors can be found in LCD in today�s modern world. A quality industrial LCD display provides you with a clear, crystal picture that can�t be beaten anywhere on the market today. However, as with any type of modern invention LCD�s come with their own set of pros and cons. Read on below for a few of the advantages and disadvantages of going with an industrial LCD display.
You can find LCD displays in about every resolution possible. From 1080-p for cable display to 720p for plasma displays, if you need it, it�s most probably out there for sale.
It is rumored that LCD is a little bit more expensive than your average plasma flat panels on the market today. If, however, you really want a display that pops, LCD is the best bet for you.
The picture that you get with an LCD display cannot be beaten. Instead of a traditional bulb, newer LCD displays use LED lighting, also known as a light emitting diode. This allows it to have a more daylight looking effect, instead of a yellowish light that is common with normal bulbs.
While they are getting better with time, LCD�s tend to have a limited viewing angle. If you aren�t sitting right in front of the screen, it can be hard to see.
These types of displays are said to be the greenest option on the planet. They are designed to use less energy and seem to be doing so well. If you are environmentally friendly, like everyone should be these days, then you should go with LCD, for this very reason.
One of the biggest benefits to LCD displays is the lack of burn in. If you play a lot of video games or do stuff where there isn�t a lot of moving around on the screen, then LCD displays are for sure the best bet for you.
These are just a few of the pros and cons of LCD displays. If you are still on the fence, do your research, read some reviews on social media sites and then make the choice that is the right one for you and your needs. LCD industrial displays are here to stay.
The Liquified Crystal Display ( LCD ) is a flat panel display, electronic visual or video display that uses the light modulating properties of liquid crystals which do not emits the light directly. LCDs are used in televisions, computer monitors the instrument panels and the aircraft cockpit displays and the signage.
Nowadays LCDs are most commonly used in DVD players, the gaming devices, the clocks, the watches, the calculators, the telephones replaced by Cathode Ray Tube ( CRT ) in most of the applications. LCDs are available in a wider range of screen sizes compare to CRT display and a Plasma display, also they don"t use phosphors, and don"t suffer image burn-in. Following characteristics of LCD posses certain advantages and because of the latest innovation it also posses some disadvantages too. In this article, you can check it out the advantages and disadvantages briefly.
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:
• Perform highly diversified duties to install and maintain electrical apparatus on production machines and any other facility equipment (Screen Print, Punch Press, Steel Rule Die, Automated Machines, Turret, Laser Cutting Machines, etc.).
• Provide electrical emergency/unscheduled diagnostics, repairs of production equipment during production and performs scheduled electrical maintenance repairs of production equipment during machine service.
The liquid crystal display (LCD) is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals which do not emitthe lightdirectly, LCDs are used in the computer monitors, televisions, the instrument panels, the aircraft cockpit displays, and the signage.
LCDs are available to display the arbitrary images such as in a general-purpose computer display or the fixed images which can be displayed or hidden such as preset words, digits, and 7-segment displays as in a digital clock, They use the same basic technology except that the arbitrary images are made up of a large number of small pixels while other displays have larger elements.
LCDs are used in DVD players, the gaming devices, the clocks, the watches, the calculators, and the telephones, They have replaced the cathode ray tube (CRT) displays in most applications, They are available in a wider range of screen sizes than CRT and plasma displays, and they do not use phosphors, they do not suffer image burn-in, LCDs are susceptible to image persistence.
LCD’s have no radiation emission from the screen, they are better under brighter conditions because of anti-glare technology, and LCD TVs are not affected by the increase or decrease in the air pressure.
LCD’s are lighter in weight with respect to the screen size, They can be used as a computer monitor, The images appear with greater resolution, and the colors of images look more realistic, They savethe electricitybills because of lower power consumption, they consume less than 1/3 the power of a comparable CRT, they consume less electricitythan a CRT and produce little heat.
LCD’s have better performance than Plasmas for smaller screen sizes, they require less power and generateless heat,They have satisfactory performance even when mounted at higher altitudes, They have a longer life span, LCDs take up about 40% less desk space, They are thin and compact.
The brightness range of LCD’s is wider, They produce very bright images due to high peak intensity, Very suitable for environments that are brightly lit, and they produce lower electric, magnetic and electromagnetic fields than CRTs.
The image is perfectly sharp at the native resolution of the panel, LCDs using an analog input require careful adjustment of pixel phase, and high peak intensity produces very bright images, Best for brightly lit environments.
There is zero geometric distortion at the native resolution of the panel, There is minor distortion for other resolutions because the images must be rescaled, and the screens are perfectly flat, and they have a superior resolution, and they have sharp resolution and imagery.
LCDs are easy disposal, they have excellent contrast, They are immune to screen image burn-in, the screens are available in a vast range of sizes, and they are used in the battery-powered electronics, and they have low flicker rates.
LCDs are more expensive compared to Plasma TV of the same size, they have less picture quality when viewed on the side or at an angle, and there is motion delay for the fast-moving images.
The interference may require frequent readjustments throughout the day due to timing drift and jitter, Analog input requires careful modification of the pixel phase to decrease or eliminate the digital noise in the image.
The aspect ratio and resolution are fixed, LCDs are not proficient at producing black and very dark grays, In a “standard” configuration, they are not appropriate for use in dimly lit and dark conditions.
The contrast adjustment is narrower in range than CRTs due to a poor black level, the response time is longer, Color saturation is reduced at low-intensity levels due to a poor black level, the images are satisfactory but they are not accurate due to problems with black level, grayscale and Gamma.
LCD have white saturation, the saturation and compression can occur due to the bright end of the intensity scale becoming overloaded, the contrast control must be adjusted.
LCDs are more fragile than CRTs, Touching an LCD screen with your fingers hard can leave pressure marks that forever mar the display, Touching a CRT with fingers will simply leave fingerprints that can be cleaned off, If you break a CRT monitor, you can get another for free or very inexpensively, LCD’s will cost a little to a lot more to replace if broken.
They have limited viewing angle, the Brightness, contrast, gamma and color mixtures vary with the viewing angle, they can lead to contrast and color reversal at large angles, they need to be viewed as close to straight ahead as possible.
LCDs can have many weak or stuck pixels which are permanently on or off, Some pixels may be improperly connected to adjoining pixels, rows, or columns, the panel may not be uniformly illuminated by the backlight resulting in uneven intensity and shading over the screen.
LCD is not as energy efficient as theLED, In dimly lit environments, brightness is compromised, It is not as good at LEDin graduating shades of color, at lower refresh rates, the motion may be blurry for some viewers.
The traditional CRT display has been developed for several decades, and its technical structure has limited its further development. Vacuum CATHODE ray tube inherent several major shortcomings cause CRT display more and more difficult to adapt to the further improvement of consumer demand for displays, at this time, flat panel display devices, the most likely to replace THE CRT display in THE PC display terminal monopoly position is the LCD display.
1. Zero radiation, low energy consumption, low heat dissipation. The principle of an LCD display is to restore the screen by twisting the deflection Angle of the liquid crystal molecules in the liquid crystal pixels to the background light. There is no such thing as a CRT with ultra-high pressure components inside, so as not to cause excessive X-ray emission caused by high pressure. Moreover, the machine structure circuit is simple, modularization and high integration of the chip is enough to minimize the electromagnetic radiation generated when the circuit works. This design directly reduces the power consumption of the circuit, and the calorific value is also very low.LCD displays (LCDs), while working, may produce slight electromagnetic radiation, but are easily resolved by shielding circuits.CRT displays are not allowed to leak radiation by drilling holes into the shield for heat dissipation.
2. Thin and light. It was the advent of LCD displays that made the invention of portable computers possible. Similarly, desktop LCDs, while larger in size and weight than laptops pale in comparison to the clunky CRT displays. Compared to a 15-inch display, CRT displays are typically nearly 50 centimeters deep, while the latest GREAT White shark LCD, NF-1500MA, is less than 5 centimeters deep! With the change of consumption viewpoint and living environment, people have higher and higher requirements on the volume and weight of household electrical appliances.LCD display (LCD) is the most likely display device to break the CRT display monopoly because of its thin and light nature.
3. Accurate image restoration. The LCD adopts the direct digital addressing display mode, which can directly display the video signal output from the graphics card on the LCD pixel one to one according to the “address” signal in the signal level after the AD conversion.CRT displays display images by deflecting coils that generate electromagnetic fields to control the periodic scanning of the electron beam on the screen. The absolute positioning of the electron beam on the screen cannot be achieved because the trajectory of the electron beam is easily affected by the environmental magnetic field or geomagnetic field. Therefore, CRT displays are prone to geometric distortion, linear distortion, and other phenomena that cannot be fundamentally eliminated.LCD displays do not. The LCD can present the picture perfectly on the screen without any geometric distortion or linear distortion.
4. display character sharp. The picture is stable and does not flicker. The unique display principle of LCD determines that all pixels on the screen emit light evenly, and the pixels of red, green, and blue primary colors are closely arranged. The video signal is sent directly to the back of the pixels to drive the pixel to emit light, so the convergence and poor focus inherent in traditional CRT display will not occur. As a result, the LCD text display effect compared with the traditional CRT display has a world of difference.LCD font is very sharp, no CRT display text when the font blur, font color phenomenon. Moreover, since the LCD display is always glowing after being powered on, the backlight lamp works under high frequency, and the display picture is stable but does not flicker, which is conducive to the long-term use of the computer.CRT displays emit light by repeatedly striking the phosphor with an electron beam, which causes the brightness to flicker periodically. It is easy to cause eye discomfort after using it for a long time.
5. Easy screen adjustment. The direct addressing display mode of an LCD display makes the screen adjustment of LCD display need not too much geometric adjustment and linear adjustment as well as the position adjustment of display content. The LCD screen can be easily adjusted to the optimal position automatically after chip calculation, in this step you just need to press the “Auto” button to complete. Eliminates the cumbersome tuning of CRT displays. You just need to manually adjust the brightness and contrast of the screen to make the machine work at its best.
These natural advantages of LCD displays (LCDs) pose enough of a threat to CRT displays. The only regret is that LCDs are still relatively expensive due to the cost of making them.
Now on the market has a lot of low-priced 14 and 15 inch LCD sales, many businesses will also boost to the sky, LCD, admittedly, LCD has a lot of very clear a bit, just because of various reasons, the current sale low price of liquid crystal are belong to the inside of the LCD products “low-end”, itself has many inherent shortcomings, let’s analyze in detail exactly what are the disadvantages of the LCD display.
Although said to be low price, but he CRT compares, the price of the LCD display is in monitor family it may be said “noble price”, it is 15 inches only 3000 yuan, and the flat display of the same size also does not cross 1000 yuan or so. Experts say the high quality of LCD screens is mainly due to the low yield rate in the manufacturing process, resulting in the cost cannot being reduced. At present, only Some manufacturers in Japan and Taiwan are able to produce LCD screens, the technology has not completely spread, there has not been a competitive situation of mass production, and the quality is also very different. In the international market, the price difference between different grades can be as much as tens to hundreds of dollars.
Digital interfaces for LCD displays (LCDs) are lonely at the top. Theoretically speaking, LCD display is pure digital equipment, and the connection of the computer host should also be to use digital interface, the advantage of using a digital interface is self-evident. Firstly, signal loss and interference can be reduced in the process of analog-to-digital conversion. Reduce the corresponding conversion circuits and components; Secondly, there is no need to adjust the clock frequency and vector.
However, most of the low-priced LCDs on the market use analog interfaces, which have problems such as vulnerable signal transmission interference, the need to add analog-to-digital conversion circuits inside the display, and the inability to upgrade to digital interfaces. Moreover, in order to avoid the occurrence of pixel flicker, the clock frequency, vector, and analog signal must be completely consistent.
In addition, LCD digital interfaces have not yet been standardized, and display CARDS with digital output are rare on the market. Come so, the key advantage of the LCD display is brought into full play hard, however. For now, the result of early consumption is a costly display.
Early LCDs had a visual deflection Angle of only 90 degrees and could only be viewed from the front, with greater brightness and color distortion when viewed from the side.LCD displays now on the market typically have a visual deflection Angle of about 140 degrees, which is enough for personal use, but if several people are watching at the same time, the problem of distortion becomes apparent.
Response time is a special indicator of LCD. The response time of the LCD display refers to the response speed of each pixel of the display to the input signal. If the response time is short, there will be no image trailing when displaying the moving picture. This is important when playing games and watching a fast-moving video. A fast enough response time ensures a consistent picture. At present, the response time of ordinary LCD displays on the market has made a great breakthrough compared with the previous ones, which is generally about 40ms. But it still fails to meet the demand for 3D games and high-quality DVD movies.
Do you want a flashlight? The joke is about the brightness and contrast of LCD monitors. Since liquid crystal molecules cannot emit light by themselves, LCD displays need to rely on external light sources to assist in emitting light. Generally speaking, 140 lumens per square meter is enough. There is still a gap between the parameter standards of some manufacturers and the actual standards. It should be noted that some small LCDs used to be mainly used in laptop computers, with two light adjustments, so their brightness and contrast are not very good.
Liquid crystal “bad point” problem. The material of the LCD display screen is generally made of glass, which is easy to be broken. In addition, every pixel is very small, which often causes the phenomenon of individual pixels being broken, commonly known as “bad point”. This is not repairable, and only the replacement of the whole display screen is often very expensive.
The launch of a new product has its own advantages over old products. The advantage of an LCD display is that it is light, simple, and environmentally friendly eye protection. However, due to the current LCD products at the same time, there are defects, not enough to meet all the needs of consumers. Under the premise of such product technology, do not blindly follow the fashion trend, but recognize their own needs and product characteristics, to make the most objective and practical choice.
Liquid-crystal display (LCD) monitors are the most common today. They generally consist of a liquid crystal panel and a fluorescent backlight system located at the back of the screen. The images are shown when the light from the feedback system hits the screen.
LCD monitors are characterized by their flat, thin, and durable screens. Besides, they have had integrated LED feedback for some years now, which is why manufacturers often talk about LED LCDs. These monitors generally have low energy consumption and are affordable.
LCD monitors have many benefits to offer. As we just mentioned, they have extremely low energy consumption, and you can find very affordable models. They also allow you to enjoy very vivid colors and high definition levels.
You will have to evaluate a series of key criteria before you can choose the LCD monitor that best fits your needs. Since we want to make your life easier, we have selected the most important aspects to consider and have detailed them in the following section. This will help you sort through the wide array of options on the market, and you will know how to pick a monitor that offers the performance and value for the money you’re looking for.
You won’t want the same type of monitor if you often play video games on your computer or if you only use it for browsing the internet and office tasks. This is why the very first aspect you should think about is how exactly you plan on using your LCD monitor.
Even if you are looking for a gaming monitor, you will have to choose a model suitable for the type of game you play. If you are into competitive games, you should choose one with a low response time. For graphic design or to view content in high definition, on the other hand, your best bet will be a VA panel.
The screen size of a monitor is generally expressed as a function of the length of its diagonal in inches. The size of the screen you choose should, in part, be determined by the area of your home or office where you want to fit the monitor. That being said, the vast majority of LCD monitors currently vary between 24 and 27 inches in size.
Did you know that LCD, called liquid-crystal display, means that electrical pulses form the basis for the alignment of the crystals, which produce different colors due to their uneven light transmission?
As we briefly mentioned earlier, there are three main types of panels for monitors and TVs: TN, IPS, and VA. Each one has its own features and is more tailored to a specific type of use.
We have entered the age of 4K resolution, and we are already starting to talk about 8K resolutions. In any case, if you use your computer for navigation or office tasks, Full HD resolution will be plenty enough for you. This is quite different if you want to play video games intensively.
If this is your case, you should start your search by looking at monitors with 4K resolution. Do keep in mind that a high-quality LCD monitor isn’t enough; you still need to have a powerful enough computer. Since more and more 4K content is being released, you may also be interested in these monitors if you are a cinephile.
High dynamic range (HDR) technology has become increasingly common in monitors and televisions in the last few years. It makes it possible to offer colors that are much closer to those we can see in reality. Another fantastic benefit of HDR is that it can independently illuminate different areas of the monitor.
This high-dynamic range means that you can enjoy a higher contrast in the image. The main advantages of this technology are, therefore, the illumination of the different scenes and the incredibly vivid colors it offers. Remember that there are currently different HDR standards: HDR10, Dolby Vision, HDR10+, and HLG.
The video ports are naturally the most important connectors on a monitor. The most efficient and widely used is the HDMI port, so we strongly encourage you to choose a model with at least two. Depending on what equipment you want to connect your monitor to, you may also need a VGA or DVI port—especially for older computers.
The greatest advantage of the HDMI port is that it also allows you to transmit audio. DVI ports, on the other hand, support higher refresh rates. You may also think about the DisplayPort connection as it offers the best bandwidth. As you can imagine, it’s never a bad idea to have an LCD monitor with a couple of USB ports as well.
Currently, the vast majority of manufacturers use the 16:9 aspect ratio. That said, the more recent 21:9 aspect ratio is increasingly common. It allows us to work with high diagonals and for tasks where you need many windows at the same time, including the use of multimedia equipment.
There is a common misconception that having a higher image resolution is necessarily better. Actually, this isn’t always true. If you decide to purchase a monitor between 21 and 24 inches, the most convenient option is Full HD (1080p) resolution. From 24 inches onward, it"s recommended that you choose 4K models.
If you are an avid gamer, on the other hand, you may also be interested in the 1440p resolution, which won’t be so heavy on your graphics card. Don’t hesitate to go for an HDR 4K monitor if you have a desktop computer with a powerful graphics card or a gaming console. The latest video games will be perfect for you to make the most of this resolution.
First of all, there is often a direct relationship between the size of the screen and the price of the monitor. However, we’re sure you will have guessed that it isn’t the only influencing factor in the final cost of the product. The type of panel is another element that plays a significant role in this, the three main ones being TN, VA, and IPS.
The most expensive panels are currently the IPS models, although their price has dramatically decreased in recent years. Also, the image resolution and HDR technology are factors to consider in the final cost of an LCD monitor. If you are looking for a gaming model, keep in mind that they often integrate specific technologies to offer better in-game performance and are, therefore, more expensive.
Computer monitor manufactures are continuously seeking ways to improve liquid crystal display (LCD) and cathode ray tube (CTR) monitors. Some of the technological achievements include LCDs’ response time and color clarity, making them faster and able to handle a wide range of computing work such as editing, gaming and design. The monitors vary in durability, power consumption and safety measures. Choosing a monitor that suits your computing needs requires you to take the advantages and the disadvantages of monitors into consideration.
LCD monitors with Energy Star ratings use little electricity in comparison to CRT machines as LCDs consume 25 watts to 50 watts, while CRT monitors consume 60 watts to 80 watts. You can determine the exact amount of power a monitor consumes using online power consumption calculators. This makes it possible for individuals or businesses to keep track of overhead costs such as electricity bills and come up with beneficial energy-saving measures.
According to a research by Jon Peddie, the founder of Jon Peddie Research and a graphics industry pioneer, using two monitors at the same time increases productivity by 20 percent to 30 percent. Multiple monitors make it possible for professionals such as fashion and graphic designers to compare their current designs with other designers’ or their own previous works. Modern Macs and Windows computers allow you to plug in two monitors.
Monitors emit extremely low frequency (EFL) radiation and microwave radiation, which are harmful to human health. These types of radiation have electromagnetic properties that penetrate solids, including the human body. People who stay in front of monitors for long can develop heart diseases and cancer as results of EFL and microwaves radiation. Sit two feet (about 60 cm) away from the computer to minimize the radiation effects and this might be difficult for people with poor eyesight.
LCD monitors are costly to buy and maintain and limits an individual or a company’s ability to acquire them. LCD monitors require frequent monitoring to ensure that the drivers are computer virus free and are working properly. Malfunctioning monitor drivers can hinder efficient performance of certain software applications and this can lower the quality of work done using the monitor.
CRT monitors have low refreshing ability known as the flickering effect. This lowers productivity because the user has to wait for some time for the monitor to respond to a command. The flicker effect can also make you lose interest when performing computing tasks that require heavy software applications such as video game programming or web design.

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.
Since the production of cathode ray tubes has essentially halted due to the cost and environmental concerns, CRT-based monitors are considered an outdated technology. All laptops and most desktop computer systems sold today come with LCD monitors. However, there are a few reasons why you might still prefer CRT over LCD displays.
While CRT monitors provide better color clarity and depth, the fact that manufacturers rarely make them anymore makes CRTs an unwise choice. LCD monitors are the current standard with several options. LCD monitors are smaller in size and easier to handle. Plus, you can buy LCD monitors in a variety of sizes, so customizing your desktop without all the clutter is easy.
The primary advantage that CRT monitors hold over LCDs is color rendering. The contrast ratios and depths of colors displayed on CRT monitors are better than what an LCD can render. For this reason, some graphic designers use expensive and large CRT monitors for their work. On the downside, the color quality degrades over time as the phosphors in the tube break down.
Another advantage that CRT monitors hold over LCD screens is the ability to easily scale to various resolutions. By adjusting the electron beam in the tube, the screen can be adjusted downward to lower resolutions while keeping the picture clarity intact. This capability is known as multisync.
The biggest disadvantage of CRT monitors is the size and weight of the tubes. An equivalently sized LCD monitor can be 80% smaller in total mass. The larger the screen, the bigger the size difference. CRT monitors also consume more energy and generate more heat than LCD monitors.
For the most vibrant and rich colors, CRTs are hard to beat if you have the desk space and don"t mind the excessive weight. However, with CRTs becoming a thing of the past, you may have to revisit the LCD monitor.
The biggest advantage of LCD monitors is the size and weight. LCD screens also tend to produce less eye fatigue. The constant light barrage and scan lines of a CRT tube can cause strain on heavy computer users. The lower intensity of the LCD monitors coupled with the constant screen display of pixels being on or off is easier on the eyes. That said, some people have issues with the fluorescent backlights used in some LCD displays.
The most notable disadvantage to LCD screens is the fixed resolution. An LCD screen can only display the number of pixels in its matrix. Therefore, it can display a lower resolution in one of two ways: using only a fraction of the total pixels on the display, or through extrapolation. Extrapolation blends multiple pixels together to simulate a single smaller pixel, which often leads to a blurry or fuzzy picture.
For those who are on a computer for hours, an LCD can be an enemy. With the tendency to cause eye fatigue, computer users must be aware of how long they stare at an LCD monitor. While LCD technology is continually improving, using techniques to limit the amount of time you look at a screen alleviates some of that fatigue.
Significant improvements have been made to LCD monitors over the years. Still, CRT monitors provide greater color clarity, faster response times, and wider flexibility for video playback in various resolutions. Nonetheless, LCDs will remain the standard since these monitors are easier to manufacture and transport. Most users find LCD displays to be perfectly suitable, so CRT monitors are only necessary for those interested in digital art and graphic design.
If you are looking for a new display, you should consider the differences between CRT and LCD monitors. Choose the type of monitor that best serves your specific needs, the typical applications you use, and your budget.
Require less power - Power consumption varies greatly with different technologies. CRT displays are somewhat power-hungry, at about 100 watts for a typical 19-inch display. The average is about 45 watts for a 19-inch LCD display. LCDs also produce less heat.
Smaller and weigh less - An LCD monitor is significantly thinner and lighter than a CRT monitor, typically weighing less than half as much. In addition, you can mount an LCD on an arm or a wall, which also takes up less desktop space.
More adjustable - LCD displays are much more adjustable than CRT displays. With LCDs, you can adjust the tilt, height, swivel, and orientation from horizontal to vertical mode. As noted previously, you can also mount them on the wall or on an arm.
Less eye strain - Because LCD displays turn each pixel off individually, they do not produce a flicker like CRT displays do. In addition, LCD displays do a better job of displaying text compared with CRT displays.
Better color representation - CRT displays have historically represented colors and different gradations of color more accurately than LCD displays. However, LCD displays are gaining ground in this area, especially with higher-end models that include color-calibration technology.
More responsive - Historically, CRT monitors have had fewer problems with ghosting and blurring because they redrew the screen image faster than LCD monitors. Again, LCD manufacturers are improving on this with displays that have faster response times than they did in the past.
Multiple resolutions - If you need to change your display"s resolution for different applications, you are better off with a CRT monitor because LCD monitors don"t handle multiple resolutions as well.
So now that you know about LCD and CRT monitors, let"s talk about how you can use two monitors at once. They say, "Two heads are better than one." Maybe the same is true of monitors!
If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?
So, why is this important? A monitor’s panel technology is important because it affects what the monitor can do and for which uses it is best suited. Each of the monitor panel types listed above offer their own distinctive benefits and drawbacks.
Choosing which type of monitor panel type to buy will depend largely on your intended usage and personal preference. After all, gamers, graphic designers, and office workers all have different requirements. Specific types of displays are best suited for different usage scenarios.
The reason for this is because none of the different monitor panel types as they are today can be classified as “outstanding” for all of the attributes mentioned above.
Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.
IPS monitors or “In-Plane Switching” monitors, leverage liquid crystals aligned in parallel to produce rich colors. IPS panels are defined by the shifting patterns of their liquid crystals. These monitors were designed to overcome the limitations of TN panels. The liquid crystal’s ability to shift horizontally creates better viewing angles.
IPS monitors continue to be the display technology of choice for users that want color accuracy and consistency. IPS monitors are really great when it comes to color performance and super-wide viewing angles. The expansive viewing angles provided by IPS monitors help to deliver outstanding color when being viewed from different angles. One major differentiator between IPS monitors and TN monitors is that colors on an IPS monitor won’t shift when being viewed at an angle as drastically as they do on a TN monitor.
IPS monitor variations include S-IPS, H-IPS, e-IPS and P-IPS, and PLS (Plane-to-Line Switching), the latter being the latest iteration. Since these variations are all quite similar, they are all collectively referred to as “IPS-type” panels. They all claim to deliver the major benefits associated with IPS monitors – great color and ultra-wide viewing angles.
When it comes to color accuracy, IPS monitors surpass the performance of TN and VA monitors with ease. While latest-gen VA technologies offer comparative performance specs, pro users still claim that IPS monitors reign supreme in this regard.
Another important characteristic of IPS monitors is that they are able to support professional color space technologies, such as Adobe RGB. This is due to the fact that IPS monitors are able to offer more displayable colors, which help improve color accuracy.
In the past, response time and contrast were the initial weakness of IPS technology. Nowadays, however, IPS monitor response times have advanced to the point where they are even capable of satisfying gamers, thus resulting in a rising popularity in IPS monitors for gaming.
With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.
IPS monitors deliver ultra-wide 178-degree vertical and horizontal viewing angles. Graphic designers, CAD engineers, pro photographers, and video editors will benefit from using an IPS monitor. Many value the color benefits of IPS monitors and tech advances have improved IPS panel speed, contrast, and resolution. IPS monitors are more attractive than ever for general desktop work as well as many types of gaming. They’re even versatile enough to be used in different monitor styles, so if you’ve ever compared an ultrawide vs. dual monitor setup or considered the benefits of curved vs. flat monitors, chances are you’ve already come into contact with an IPS panel.
TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.
Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.
On the flip side, however, TN panel technology tends to be ill-suited for applications that benefit from wider viewing angles, higher contrast ratios, and better color accuracy. That being said, LED technology has helped shift the perspective and today’s LED-backlit TN models offer higher brightness along with better blacks and higher contrast ratios.
The greatest constraint of TN panel technology, however, is a narrower viewing angle as TN monitors experience more color shifting than other types of panels when being viewed at an angle.
Today’s maximum possible viewing angles are 178 degrees both horizontally and vertically (178º/178º), yet TN panels are limited to viewing angles of approximately 170 degrees horizontal and 160 degrees vertical (170º /160º).
In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.
For general-purpose use, these shifts in color and contrast are often irrelevant and fade from conscious perception. However, this color variability makes TN monitors a poor choice for color-critical work like graphic design and photo editing. Graphic designers and other color-conscious users should also avoid TN displays due to their more limited range of color display compared to the other technologies.
TN monitors are the least expensive panel technology, making them ideal for cost-conscious businesses and consumers. In addition, TN monitors enjoy unmatched popularity with competitive gamers and other users who seek rapid graphics display.
Vertical alignment (VA) panel technology was developed to improve upon the drawbacks of TN. Current VA-based monitors offer muchhigher contrast, better color reproduction, and wider viewing angles than TN panels. Variations you may see include P-MVA, S-MVA, and AMVA (Advanced MVA).
These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.
Contrast ratio is the measured difference between the darkest blacks and the brightest whites a monitor can produce. This measurement provides information about the amount of grayscale detail a monitor will deliver. The higher the contrast ratio, the more visible detail.
These monitors also provide more visible details in shadows and highlights, making them ideal for enjoying videos and movies. They’re also a good fit for games focused on rich imagery (RPG games for example) rather than rapid speed (such as FPS games).
MVA and other recent VA technologies offer the highest static contrast ratios of any panel technology. This allows for an outstanding visual experience for movie enthusiasts and other users seeking depth of detail. Higher-end, feature-rich MVA displays offer the consistent, authentic color representation needed by graphic designers and other pro users.
There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.
When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.
With the lowest cost and fastest response times, TN monitors are great for general use and gaming. VA monitor offers a step up for general use. Maxed-out viewing angles and high contrast ratios make VA monitors great for watching movies and image-intensive gaming.
IPS monitors offer the greatest range of color-related features and remain the gold standard for photo editing and color-critical pro uses. Greater availability and lower prices make IPS monitors a great fit for anyone who values outstanding image quality.
LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.
While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.
Liquid Crystals (LCs) are used because of their unique ability to maintain a parallel shape. Acting as both a solid and liquid, LCs are able to react quickly to changes in light patterns. The optical properties of LCs are activated by electric current, which is used to switch liquid crystals between phases. In turn, each pixel generates an RGB (red, green, blue) color based on the phase it’s in.
Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.
Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.
As a result, active-matrix technology was invented and transistors (TFTs) began being used to help liquid crystals retain their charge and change phase more quickly.
Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.
Ultimately, budget and feature preferences will determine the best fit for each user. Among the available monitors of each panel type there will also be a range of price points and feature sets. Additionally, overall quality may vary among manufacturers due to factors related to a display’s components, manufacturing, and design.
If you’re interested in learning more about IPS monitors, you can take a look at some of these professional monitors to see if they would be the right fit for you.
Alternatively, if you’re into gaming and are in the market for TN panel these gaming monitor options may be along the lines of what you’re looking for.
