tft lcd vs led ips in stock
If you want to buy a new monitor, you might wonder what kind of display technologies I should choose. In today’s market, there are two main types of computer monitors: TFT LCD monitors & IPS monitors.
The word TFT means Thin Film Transistor. It is the technology that is used in LCD displays. We have additional resources if you would like to learn more about what is a TFT Display. This type of LCDs is also categorically referred to as an active-matrix LCD.
These LCDs can hold back some pixels while using other pixels so the LCD screen will be using a very minimum amount of energy to function (to modify the liquid crystal molecules between two electrodes). TFT LCDs have capacitors and transistors. These two elements play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy while still generating vibrant, consistent images.
Industry nomenclature: TFT LCD panels or TFT screens can also be referred to as TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology.
IPS (in-plane-switching) technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but has more enhanced features and more widespread usability.
These LCD screens offer vibrant color, high contrast, and clear images at wide viewing angles. At a premium price. This technology is often used in high definition screens such as in gaming or entertainment.
Both TFT display and IPS display are active-matrix displays, neither can’t emit light on their own like OLED displays and have to be used with a back-light of white bright light to generate the picture. Newer panels utilize LED backlight (light-emitting diodes) to generate their light hence utilizing less power and requiring less depth by design. Neither TFT display nor IPS display can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to produce the color consumers see. If you use a magnifier to inspect your monitor, you will see RGB color in each pixel. With an on/off switch and different level of brightness RGB, we can get many colors.
Winner. IPS TFT screens have around 0.3 milliseconds response time while TN TFT screens responds around 10 milliseconds which makes the latter unsuitable for gaming
Winner. the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.
As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.
Winner. While the TFT LCD has around 15% more power consumption vs IPS LCD, IPS has a lower transmittance which forces IPS displays to consume more power via backlights. TFT LCD helps battery life.
Normally, high-end products, such as Apple Mac computer monitors and Samsung mobile phones, generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology.
What you need to choose is AMOLED for your TV and mobile phones instead of PMOLED. If you have budget leftover, you can also add touch screen functionality as most of the touch nowadays uses PCAP (Projective Capacitive) touch panel.
This kind of touch technology was first introduced by Steve Jobs in the first-generation iPhone. Of course, a TFT LCD display can always meet the basic needs at the most efficient price. An IPS display can make your monitor standing out.
Before you get a new monition for your organization, comparing the TFT display vs IPS display is something that you should do. You would want to buy the monitor which is the most advanced in technology. Therefore, understanding which technology is good for your organization is a must. click to view the 7 Best Types Of Display Screens Technology.
Technology is changing and becoming advanced day by day. Therefore, when you are looking to get a new monitor for your organization, LCD advantages, and disadvantage, you have to be aware of the pros and cons of that monitor. Moreover, you need to understand the type of monitor you are looking to buy.
That is why it is important to break it down and discuss point by point so that you can understand it in a layman’s language devoid of any technical jargon. Therefore, in this very article, let’s discuss what exactly TFT LCDs and IPS LCDs are, and what are their differences? You will also find out about their pros and cons for your organization.
The word TFT means Thin-Film-Translator. It is the technology that is used in LCD or Liquid Crystal Display. Here you should know that this type of LCD is also categorically referred to as active-matrix LCDs. It tells that these LCDs can hold back some pixels while using other pixels. So, the LCD will be using a very minimum amount of energy to function. TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the display monitor functions by using a very small amount of energy without running out of operation.
Now, it is time to take a look at its features that are tailored to improve the experience of the monitor users significantly. Here are some of the features of the TFT monitor;
No radiation, no scintillation, no harm to the user’s health. In particular, the emergence of TFT LCD electronic books and periodicals will bring humans into the era of a paperless office and paperless printing, triggering a revolution in the civilized way of human learning, dissemination, and recording.
It can be normally used in the temperature range from -20℃ to +50℃, and the temperature-hardened TFT LCD can operate at low temperatures up to -80 ℃. It can not only be used as a mobile terminal display, or desktop terminal display but also can be used as a large screen projection TV, which is a full-size video display terminal with excellent performance.
The manufacturing technology has a high degree of automation and good characteristics of large-scale industrial production. TFT LCD industry technology is mature, a mass production rate of more than 90%.
TFT LCD screen from the beginning of the use of flat glass plate, its display effect is flat right angles, let a person have a refreshing feeling. And LCDs are easier to achieve high resolution on small screens.
The word IPS refers to In-Plane-Switching which is a technology used to improve the viewing experience of the usual TFT displays. You can say that the IPS display is a more advanced version of the traditional TFT LCD module. However, the features of IPS displays are much more advanced and their applications are very much widespread. You should also know that the basic structure of the IPS LCD is the same as TFT LCD if you compare TFT LCD vs IPS.
As you already know, TFT displays do have a very quick response time which is a plus point for it. But, that does not mean IPS displays a lack of response time. In fact, the response time of an IPS LCD is much more consistent, stable, and quick than the TFT display that everyone used to use in the past. However, you will not be able to gauge the difference apparently by watching TFT and IPS displays separately. But, once you watch the screen side-by-side, the difference will become quite clear to you.
The main drawback of the TFT displays as figured above is the narrow-angle viewing experience. The monitor you buy for your organization should give you an experience of wide-angle viewing. It is very much true if you have to use the screen by staying in motion.
So, as IPS displays are an improved version of TFT displays the viewing angle of IPS LCDs is very much wide. It is a plus point in favor of IPS LCDs when you compare TFT vs IPS. With a TFT screen, you cannot watch an image from various angles without encountering halo effects, blurriness, or grayscale that will cause problems for your viewing.
It is one of the major and remarkable differences between IPS and TFT displays. So, if you don’t want to comprise on the viewing angles and want to have the best experience of viewing the screen from wide angles, the IPS display is what you want. The main reason for such a versatile and wonderful viewing angle of IPS display is the screen configuration which is widely set.
Now, when you want to achieve wide-angle viewing with your display screen, you need to make sure it has a faster level of frequency transmittance. It is where IPS displays overtake TFT displays easily in the comparison because the IPS displays have a much faster and speedier transmittance of frequencies than the TFT displays.
Now the transmittance difference between TFT displays and IPS displays would be around 1ms vs. 25ms. Now, you might think that the difference in milliseconds should not create much of a difference as far as the viewing experience is concerned. Yes, this difference cannot be gauged with a naked eye and you will find it difficult to decipher the difference.
However, when you view and an IPS display from a side-by-side angle and a TFT display from a similar angle, the difference will be quite evident in front of you. That is why those who want to avoid lagging in the screen during information sharing at a high speed; generally go for IPS displays. So, if you are someone who is looking to perform advanced applications on the monitor and want to have a wider viewing angle, then an IPS display is the perfect choice for you.
As you know, the basic structure of the IPS display and TFT displays are the same. So, it is quite obvious that an IPS display would use the same basic colors to create various shades with the pixels. However, there is a big difference with the way a TFT display would produce the colors and shade to an IPS display.
The major difference is in the way pixels get placed and the way they operate with electrodes. If you take the perspective of the TFT display, its pixels function perpendicularly once the pixels get activated with the help of the electrodes. It does help in creating sharp images.
But the images that IPS displays create are much more pristine and original than that of the TFT screen. IPS displays do this by making the pixels function in a parallel way. Because of such placing, the pixels can reflect light in a better way, and because of that, you get a better image within the display.
As the display screen made with IPS technology is mostly wide-set, it ensures that the aspect ratio of the screen would be wider. This ensures better visibility and a more realistic viewing experience with a stable effect.
As you already know the features of both TFT and IPS displays, it would be easier for you to understand the difference between the two screen-types. Now, let’s divide the matters into three sections and try to understand the basic differences so that you understand the two technologies in a compressive way. So, here are the difference between an IPS display and a TFT display;
Now, before starting the comparison, it is quite fair to say that both IPS and TFT displays have a wonderful and clear color display. You just cannot say that any of these two displays lag significantly when it comes to color clarity.
However, when it comes to choosing the better display on the parameter of clarity of color, then it has to be the IPS display. The reason why IPS displays tend to have better clarity of color than TFT displays is a better crystal oriental arrangement which is an important part.
That is why when you compare the IPS LCD with TFT LCD for the clarity of color, IPS LCD will get the nod because of the better and advanced technology and structure.
IPS displays have a wider aspect ratio because of the wide-set configuration. That is why it will give you a better wide-angle view when it comes to comparison between IPS and TFT displays. After a certain angle, with a TFT display, the colors will start to get a bit distorted.
But, this distortion of color is very much limited in an IPS display and you may see it very seldom after a much wider angle than the TFT displays. That is why for wide-angle viewing, TFT displays will be more preferable.
When you are comparing TFT LCD vs. IPS, energy consumption also becomes an important part of that comparison. Now, IPS technology is a much advanced technology than TFT technology. So, it is quite obvious that IPS takes a bit more energy to function than TFT.
Also, when you are using an IPS monitor, the screen will be much larger. So, as there is a need for much more energy for the IPS display to function, the battery of the device will drain faster. Furthermore, IPS panels cost way more than TFT display panels.
1. The best thing about TFT technology is it uses much less energy to function when it is used from a bigger screen. It ensures that the cost of electricity is reduced which is a wonderful plus point.
2. When it comes to visibility, the TFT technology enhances your experience wonderfully. It creates sharp images that will have no problems for older and tired eyes.
1. One of the major problems of TFT technology is that it fails to create a wider angle of view. As a result, after a certain angle, the images in a TFT screen will distort marring the overall experience of the user.
Although IPS screen technology is very good, it is still a technology based on TFT, the essence of the TFT screen. Whatever the strength of the IPS, it is a TFT-based derivative.
Finally, as you now have a proper understanding of the TFT displays vs IPS displays, it is now easier for you when it comes to choose one for your organization. Technology is advancing at a rapid pace. You should not be surprised if you see more advanced display screens in the near future. However, so far, TFT vs IPS are the two technologies that are marching ahead when it comes to making display screens.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.
The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.
A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.
As you might already be aware, there’s a large variety of versatile digital display types on the market, all of which are specifically designed to perform certain functions and are suitable for numerous commercial, industrial, and personal uses. The type of digital display you choose for your company or organization depends largely on the requirements of your industry, customer-base, employees, and business practices. Unfortunately, if you happen to be technologically challenged and don’t know much about digital displays and monitors, it can be difficult to determine which features and functions would work best within your professional environment. If you have trouble deciphering the pros and cons of using TFT vs. IPS displays, here’s a little guide to help make your decision easier.
TFT stands for thin-film-transistor, which is a variant of liquid crystal display (LCD). TFTs are categorized as active matrix LCDs, which means that they can simultaneously retain certain pixels on a screen while also addressing other pixels using minimal amounts of energy. This is because TFTs consist of transistors and capacitors that respectively work to conserve as much energy as possible while still remaining in operation and rendering optimal results. TFT display technologies offer the following features, some of which are engineered to enhance overall user experience.
The bright LED backlights that are featured in TFT displays are most often used for mobile screens. These backlights offer a great deal of adaptability and can be adjusted according to the visual preferences of the user. In some cases, certain mobile devices can be set up to automatically adjust the brightness level of the screen depending on the natural or artificial lighting in any given location. This is a very handy feature for people who have difficulty learning how to adjust the settings on a device or monitor and makes for easier sunlight readability.
One of the major drawbacks of using a TFT LCD instead of an IPS is that the former doesn’t offer the same level of visibility as the latter. To get the full effect of the graphics on a TFT screen, you have to be seated right in front of the screen at all times. If you’re just using the monitor for regular web browsing, for office work, to read and answer emails, or for other everyday uses, then a TFT display will suit your needs just fine. But, if you’re using it to conduct business that requires the highest level of colour and graphic accuracy, such as completing military or naval tasks, then your best bet is to opt for an IPS screen instead.
Nonetheless, most TFT displays are still fully capable of delivering reasonably sharp images that are ideal for everyday purposes and they also have relatively short response times from your keyboard or mouse to your screen. This is because the pixel aspect ration is much narrower than its IPS counterpart and therefore, the colours aren’t as widely spread out and are formatted to fit onto the screen. Primary colours—red, yellow, and blue—are used as the basis for creating brightness and different shades, which is why there’s such a strong contrast between different aspects of every image. Computer monitors, modern-day HD TV screens, laptop monitors, mobile devices, and even tablets all utilize this technology.
IPS (in-plane-switching) technology is almost like an improvement on the traditional TFT display module in the sense that it has the same basic structure, but with slightly more enhanced features and more widespread usability. IPS LCD monitors consist of the following high-end features.
IPS screens have the capability to recognize movements and commands much faster than the traditional TFT LCD displays and as a result, their response times are infinitely faster. Of course, the human eye doesn’t notice the difference on separate occasions, but when witnessing side-by-side demonstrations, the difference is clear.
Wide-set screen configurations allow for much wider and versatile viewing angles as well. This is probably one of the most notable and bankable differences between TFT and IPS displays. With IPS displays, you can view the same image from a large variety of different angles without causing grayscale, blurriness, halo effects, or obstructing your user experience in any way. This makes IPS the perfect display option for people who rely on true-to-form and sharp colour and image contrasts in their work or daily lives.
IPS displays are designed to have higher transmittance frequencies than their TFT counterparts within a shorter period of time (precisely 1 millisecond vs. 25 milliseconds). This speed increase might seem minute or indecipherable to the naked eye, but it actually makes a huge difference in side-by-side demonstrations and observations, especially if your work depends largely on high-speed information sharing with minimal or no lagging.
Just like TFT displays, IPS displays also use primary colours to produce different shades through their pixels. The main difference in this regard is the placement of the pixels and how they interact with electrodes. In TFT displays, the pixels run perpendicular to one another when they’re activated by electrodes, which creates a pretty sharp image, but not quite as pristine or crisp as what IPS displays can achieve. IPS display technologies employ a different configuration in the sense that pixels are placed parallel to one another to reflect more light and result in a sharper, clearer, brighter, and more vibrant image. The wide-set screen also establishes a wider aspect ratio, which strengthens visibility and creates a more realistic and lasting effect.

Confused about LED vs. LCD vs. TFT? Here"s everything you need to know. Creating or upgrading a device display or screen can involve a lot of different things, but it often comes down to one major question - what kind of display should you get?
So, there are 3 common displays LED, LCD and TFT available in the market. All terms refer to the flat-panel display, or screen, of a computer monitor or television set. In this article, we are going to differentiate between them. It will help you to choose a better one.
LCD stands for liquid crystal display. Works by adjusting the amount of light blocked. Usually has a backlight but might not (clocks, calculators, Nintendo Gameboy). The green-black ones can be very cheap and are a mature technology. Response time can be slow. An LCD display uses the light balancing qualities of crystals. Today LCDs are used in a great number of products and applications. Your TV, computer screen, calculator, cell phone and the dreaded alarm clock are all made of an LCD flat panel. Color LCDs produce the color based on two techniques: Passive matrix and active matrix. Passive matrix is the cheapest technology of the two. The other technology is called an active matrix or TFT. Active matrix displays produce really sharp and clear images.
This is a type of LCD with a thin film transistor attached to each pixel. All computer LCD screens are TFT since the early 2000s; older ones had slower response times and poorer color. Cost is now very good; power consumption is fairly good but dominated by the backlight. Has to be manufactured out of glass. The TFT layer is embedded in the screen itself, it reduces crosstalk between pixels. Crosstalk happens when a signal sends to a pixel also affects the pixel next to it. This makes the TFT technology the technology offering the best resolution and image quality. It also makes it a bit more expensive. Today TFTs have become the standard when producing LCD screens.
LED stands for a light emitting diode. As the name suggests, emits light rather than blocking it like LCD. Used for red/green/blue/white indicator lights everywhere. Some manufacturers advertise "LED" displays that are TFT screens with a white LED backlight, which is just confusing. Ones that are real LED screens are usually OLED.
Some devices actually have backlights made from Red, Green and Blue LEDs, normally referred to as RGB LED, which tend to have better color reproduction than any other display.
LED screen is just like saying that it is a plastic screen. You still have the WHOLE screen illuminated all the time and LED is "good" only for being more eco-friendly and probably more bright at max setting if you ever need this.
An LCD panel is, in fact, 2 layers of glass with some volume of Liquid Crystal in between. These two form the panel itself. The 2 layers are usually called Color Filter Glass (above) and TFT glass (below).
LCDs can’t completely prevent light from passing through, though, even during dark scenes, so dimming the light source itself aids in creating deeper blacks and more impressive contrast in the picture.
A standard TFT has a whole "lamp" behind it, illuminating the whole screen all the time. This way, you cannot have a true black, as it is still illuminated and stay grayish.
TFTs are a type of active matrix display that controls individual pixel updates several times per second on the screen to update the image relative to the content source.
TFT displays use more electricity than regular LCD screens, so they not only cost more in the first place, but they are also more expensive to operate.
LCDs use fluorescent lights while LEDs use those light emitting diodes. The fluorescent lights in an LCD are always behind the screen. On an LED, the light emitting diodes can be placed either behind the screen or around its edges.
The word TFT means Thin Film Transistor. It is the technology that is used in LCD or Liquid Crystal Display. It is also called Active Matrix LCD which differentializes from Passive Matrix LCD. A TFT substrate is composed of a matrix of pixels and ITO electrode (Indium Tin Oxide, a transparent electric conducting film) each with a TFT device and is so called array. Thousands or millions of these pixels together create an image on the display. The diagram below shows the simple structure of a pixel.
As long as there are TFT in the LCD, the LCD should be called a TFT LCD. But when the TFT LCD display was first commercialized, 100% TFT LCDs were TN (twisted Nematic) type TFT displays. As TN is a very technical term so most of the users ignored TN and named TN type TFT display as TFT display. While the newly developed TFT LCD display technologies such as IPS (in-plane-switching ) type TFT display, O-Film type TFT display (derived from TN type TFT display), MVA( Multi-domain Vertical Alignment) type TFT display, AFFS (Advanced Fringe Field Switching) type TFT display, they are widely call IPS display, O-Film display, MVA display and AFFS display. As the above terms have been used for long and widely accepted in the market, we will not try to correct the misunderstanding here. We will still use the TFT display (should be TN type TFT display) and IPS display (should be IPS type TFT display) in the following.
The twisted nematic effect (TN-LCD) was a main technology breakthrough that made LCDs practical. TN LCDs first make battery powered devices popular. TN-LCD displays led to the rapid expansion in the display field, quickly replacing other displays like LEDs, plasma, CRTs etc. By the 1990s, TN LCDs were widely used in portable electronics.
The TN display takes advantage of the ability of the nematic substance to rotate the polarization of light beams passing through it. Two polarizing filters, parallel planes of glass with their polarizing lines oriented at right angles with respect to each other, are positioned on either side of the liquid crystal. When light enters the display, it is polarized by the input filter. In the absence of an electric field, all the incoming light is transmitted. This is because the light polarization is rotated 90 degrees by the nematic liquid crystal, and the light therefore passes easily through the output filter, which is oriented to match the 90-degree shift. With the application of a voltage, an electric field is produced in the nematic liquid crystal. Under these conditions the polarization effect is reduced. If the voltage is large enough, the polarization effect disappears altogether, and the light is blocked by the output polarizing filter. The diagram below shows how a TN LCD works.
The best feature of TFT displays is the low cost due to a simpler manufacturing process, low-cost raw materials, and one of the oldest technologies for LCD displays. But they are not the best quality considering poor viewing angles, lower contrast ratio, slower response time, lower aperture ratio (each pixel not bright enough), and the worst is that there is one view angle with gray scale inversion (reversed image), see the below picture for reference.
IPS (in-plane-switching) technology is also one type of TFT LCD display. The basic LCD structure is similar to TN type TFT display but the inside display schematic is different.
In 1992, Hitachi researchers in Japan first developed details of the IPS technology. NEC and Hitachi became early manufacturers of active-matrix addressed LCDs based on the IPS technology. In 1996, Samsung developed the optical patterning technique that enables multi-domain LCD. Multi-domain and in-plane switching subsequently remained the dominant LCD designs through 2006. IPS technology is widely used in LCD panels for TVs, laptops, monitors, and smartphones. Apple Inc. products branded with the label Retina Display (such as iPhone 4 onward, iPad 3 on, iPad Mini 2 on, MacBook Pro with Retina display adopted IPS LCDs with LED backlighting.
An IPS LCD panel, when no electric field is applied to the liquid crystal cells, the cells naturally align in liquid crystal cells in a horizontal direction between two glass substrates which blocks the transmission of light from the backlight. This makes the display dark and results in a black display screen. When an electric field is applied, the liquid crystal cells are able to rotate through 90° allowing light to pass through resulting in a white display screen. IPS panels have superior image quality, good contrast ratio and wide viewing angles of up to 170°. IPS panels are well suited for graphics design and other applications which require accurate and consistent color reproduction.
In summary, normally high-end products such as Apple Mac computer monitors and Samsung mobile phones generally use IPS panels. Some high-end TV and mobile phones even use AMOLED (Active Matrix Organic Light Emitting Diodes) displays. This cutting-edge technology provides even better color reproduction, clear image quality, better color gamut, less power consumption when compared to LCD technology. Of course, a TFT LCD display can always meet the basic needs at the most efficient price.

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.
When it comes todisplay technologies such asprojectorsand panels, factors such as resolution and refresh rate are often discussed. But the underlying technology is equally, if not more, important. There are tons of different types of screens, from OLED and LED to TN, VA, and IPS. Learn about the various monitor and television types, from operation to pros and cons!

The most common form of monitor or TV on the market is LCD or Liquid Crystal Display. As the name suggests, LCDs use liquid crystals that alter the light to generate a specific colour. So some form of backlighting is necessary. Often, it’s LED lighting. But there are multiple forms of backlighting.
LCDs have utilized CCFLs or cold cathode fluorescent lamps. An LCD panel lit with CCFL backlighting benefits from extremely uniform illumination for a pretty even level of brightness across the entire screen. However, this comes at the expense of picture quality. Unlike an LED TV, cold cathode fluorescent lamp LCD monitors lack dimming capabilities. Since the brightness level is even throughout the entire array, a darker portion of scenes might look overly lit or washed out. While that might not be as obvious in a room filled with ambient light, under ideal movie-watching conditions, or in a dark room, it’s noticeable. LED TVs have mostly replaced CCFL.
An LCD panel is transmissive rather than emissive. Composition depends on the specific form of LCD being used, but generally, pixels are made up of subpixel layers that comprise the RGB (red-green-blue) colour spectrum and control the light that passes through. A backlight is needed, and it’s usually LED for modern monitors.
While many newer TVs and monitors are marketed as LED TVs, it’s sort of the same as an LCD TV. Whereas LCD refers to a display type, LED points to the backlighting in liquid crystal display instead. As such, LED TV is a subset of LCD. Rather than CCFLs, LEDs are light-emitting diodes or semiconductor light sources which generate light when a current passes through.
LED TVs boast several different benefits. Physically, LED television tends to be slimmer than CCFL-based LCD panels, and viewing angles are generally better than on non-LED LCD monitors. So if you’re at an angle, the picture remains relatively clear nonetheless. LEDs are also extremely long-lasting as well as more energy-efficient. As such, you can expect a lengthy lifespan and low power draw. Chances are you’ll upgrade to a new telly, or an internal part will go out far before any LEDs cease functioning.
Further segmenting LED TVs down, you’ll find TN panels. A TN display or Twisted Nematic display offers a low-cost solution with low response time and low input lag. TN monitors sport high refresh rates, so 100Hz, 144Hz, or higher. Thus, many monitors marketed toward gamers feature TN technology. Unfortunately, while an affordable, fast panel may sound ideal, TN panels suffer from inferior colour reproduction and horrible viewing angles. A TN panel works so that liquid crystal molecules point at the viewer, and light polarizers are oriented at 90-degree angles.
Like TN, IPS or In-plane Switching displays are a subset of LED panels. IPS monitors tend to boast accurate colour reproduction and great viewing angles. Price is higher than on TN monitors, but in-plane switching TVs generally feature a better picture when compared with twisted nematic sets. Latency and response time can be higher on IPS monitors meaning not all are ideal for gaming.
An IPS display aligns liquid crystals in parallel for lush colours. Polarizing filters have transmission axes aligned in the same direction. Because the electrode alignment differs from TN panels, black levels, viewing angles, and colour accuracy is much better. TN liquid crystals are perpendicular.
A VA or vertical alignment monitor features excellent contrast ratios, colour reproduction, and viewing angles. It’s a type of LED monitor with crystals perpendicular to the polarizers at right angles like TN monitors. Pricing varies, but response time isn’t as high as a TN monitor.
A quantum dot LED TV or QLED is yet another form of LED television. But it’s drastically different from other LED variants. Whereas most LED panels use a white backlight, quantum dot televisions opt for blue lights. In front of these blue LEDs sits a thin layer of quantum dots. These quantum dots in a screen glow at specific wavelengths of colour, either red, green, or blue, therefore comprising the entire RGB (red-green-blue) colour spectrum required to create a colour TV image.
QLED TV sets are thus able to achieve many more local dimming zones than other LED TVs. As opposed to uniform backlighting, local dimming zones can vary backlighting into zones for adjustable lighting to show accurate light and dark scenes. Quantum Dot displays maintain an excellent, bright image with precise colour reproduction.
An OLED or organic light-emitting diode display isn’t another variation of LED. OLEDs use negatively and positively charged ions for illuminating individual pixels. By contrast, LCD/LED TVs use a backlight that can make an unwanted glow. In OLED display, there are several layers, including a substrate, anode, hole injection layer, hole transport layer, an emissive layer, blocking layer, electron transport layer, and cathode. The emissive layer comprised of an electroluminescent layer of film is nestled between an electron-injecting cathode and an electron removal layer, the anode. OLEDs benefit from darker blacks and eschew any unwanted screen glow. Because OLED panels are made up of millions of individual subpixels, the pixels themselves emit light, and it’s, therefore, an emissive display as opposed to a transmissive technology like LCD/LED panels where a backlight is required behind the pixels themselves.
Image quality is top-notch. OLED TVs feature superb local dimming capabilities. The contrast ratio is unrivalled, even by the best of QLEDs, since pixels not used may be turned off. There’s no light bleed, black levels are incredible, excellent screen uniformity, and viewing angles don’t degrade the picture. Unfortunately, this comes at a cost. OLEDs are pricey, and the image isn’t as bright overall when compared to LED panels. For viewing in a darkened room, that’s fine, but ambient lighting isn’t ideal for OLED use.
What is an OLED:Organic light-emitting diode display, non-LED. Emissive technology is where negatively and positively charged ions illuminate individual pixels in a display.
As you can see, there are tons of different types of displays, each with their advantages and disadvantages. Although many monitors and TVs are referred to by different names like LED, IPS, VA, TN, or QLED, many are variations of LCD panels. However, specific technology such as the colour of backlighting and alignment of pixels dictates the picture quality. OLED is an entirely different form of display that’s not LED. Now that you understand the various types of monitors and televisions on the market, you can select the best TV to fit your needs!
LED, IPS, LCDandTFT, among others, are some names you’d commonly come across. These acronyms all have to do with a monitor or TV’s display technology.
Before we get to IPS and LED, it would be good to have a basic understanding of what is currently the most popular flat panel display technology — LCD.
The overwhelming majority of monitors and TVs that you can buy today use LCD, which stands for “liquid-crystal display.” As the name suggests,this technology uses liquid crystals to modulate light, which is provided by an active backlight in all LCD monitors.
Initially, when they were first introduced, CRT monitors had some advantages over their LCD counterparts, such as higher responsiveness and better performance. However, it didn’t take long for the new technology to catch up. LCD displays were thinner, lighter, better and more modern-looking, and they are now the dominant display technology when it comes to monitors. Similarly, they also overshadowed plasma in the TV market.
Now, we get to an important acronym, TFT. This is short for “thin-film transistor,” and without getting too deep into technobabble, let’s just say that TFT is a type of LCD technology that uses an active matrix of thin-film transistors that generally improve the image quality of an LCD.
TFT LCD displays have been around for years, and it’s almost certain that your monitor, TV and phone all use some type of TFT LCD display. But what “types” of TFT LCD displays are there, exactly? Well, that brings us to our next point.
IPS stands for in-plane switching, and it’s one of the most widespread TFT LCD panel technologies that you’ll encounter today. Along with it, you’ll also encounter TN (twisted nematic) and VA (vertical alignment panels).
As for the IPS panel itself, it was developed as a means of combating the shortcomings that were commonly present in other panel types such as poor viewing angles and limited color reproduction. As a result, most IPS panels today offer significantly wider viewing angles compared to their TN and VA counterparts, not to mention they can offer the most lifelike and vibrant colors out of these three dominant panel technologies.
But of course, IPS panels are not perfect — they tend to be the priciest of the three, they aren’t as fast and responsive as TN panels, nor can they offer the kind of contrast that a VA panel can. If you’re interested, you can read a more thorough comparison of IPS, TN and VA panels here.
Now we get to LED, which is something completely different. It is an acronym for “light-emitting diode,” and it is not a panel technology. Instead, as the name might suggest, it’s a type of backlight. As we have mentioned before, all LCDs need an active backlight, and LED is the most popular backlight technology today.
Edge-lit LEDs are positioned around the edges of the screen. Displays that use this technology are more power-efficient, and they are some of the thinnest LCDs available, which gives them a lot of aesthetic appeal. However, they might not be as bright as some displays that use a direct-lit LED backlight, and they could also have problems with backlight uniformity and ghosting.
Direct-lit LEDsare positioned behind the screen, resulting in better backlight uniformity and higher overall brightness. On the downside, besides being a bit bulkier, their contrast isn’t as great, although this can be mitigated with the help of local dimming.
Displays that use local dimmingare commonly referred to as “full-array” displays, and while the LEDs are still positioned just like in a regular direct-lit LED display, they are grouped into blocks that can be turned on or off independently, allowing certain areas of the screen to be darker than others.
That said, IPS and LED aren’t something that could be compared, but if you’re searching for comparisons of IPS and LED displays, chances are you might be thinking about OLED instead.
OLED, short for “organic light-emitting diode,” is an entirely new display technology, so it has nothing to do with LCD panels or LCD backlights. Actually, it doesn’t have anything to do with backlights at all!
Namely, while LCDs use an active backlight, an OLED display has no backlight— instead, each pixel works as its own light source, turning on to display color and turning off to display black. That said, it should be obvious from the get-go that OLED displays are more power-efficient and can offer superb contrast. But that’s not all.
As far asimage retention (or burn-in, as it’s also commonly referred to) is concerned, this is a problem that occurs when some pixels grow dimmer over time. If an OLED displays static images for long periods (which is likely to be the case with desktop use), the active pixels will lose their maximum brightness capacity much faster than those that aren’t being utilized as much, resulting in uneven brightness across the screen.
As for pricing, that one is pretty simple — the OLED manufacturing technology isn’t as developed as that of LCD, and OLED panels are significantly more expensive as a result. The supply of OLED monitors is relatively low, and if you’re an average gamer or PC user, you’d have no reason to spend thousands of dollars on one.
With all of the above in mind, it’s obvious that IPS and LED aren’t something that you can compare — the former is a type of LCD panel, while the latter is a type of LCD backlight (in this context, that is).
If you were thinking of OLED, that’s a different story. As we have mentioned above, OLEDs have many advantages not only over IPS LCD but over LCD in general. However, we feel that there is no use in discussing their advantages and disadvantages until they become more accessible to the average consumer — and if you’re waiting for that, don’t hold your breath.
At the moment, OLED monitors will mainly appeal to professionals (artists, designers, photographers, etc.) who want the best color accuracy they can get and can actually afford one of these extremely expensive monitors.
That said, if you’re shopping for a new monitor, we see LCD as the only reasonable choice in 2023. With their excellent colors and wide viewing angles, IPS panels are quite good for gaming if you prioritize visuals over performance, and they are the best choice for professionals who need high color accuracy.
But as we’ve mentioned before, IPS is not without its own drawbacks, so here’s our selection of the very best gaming monitors of 2023, in case you want to check out some good TN and VA options as well.
