what is QLED TV Display ? QLED vs OLED TV


Hello friends, we welcome you again on this lovely channel of yours. And today we are going to tell you what is QLED TV? And how does it work and how is it different from other LED TVs. In this article, we will tell you the complete information related to QLED TV and it. Let's start. By the way, when you have gone to a TV showroom to buy TV, you must have seen it there or you must have heard about it while checking online TV.

QLED is 4th generation technology. Which is available in Advance 4K, 8K and HDR, Ultra HD TVs. Talking about the earlier technology, its name is OLED, which was developed in 1987 but it was first introduced in Sony XEL-1 in 2007. QLED technology is developed after OLED technology.

Maybe you have heard the mention of your QLED or maybe you are listening to it puzzle times, Kher let us tell you what it is. QLED TV is a little advanced from the normal TV because some advanced technology has been used inside it which enhances the quality of the picture seen on its screen. Due to which the viewer feels good.


If we talk about the full form of QLED, then it is (Quantum Dot Light Emitting Diode). This is a new technology that was introduced by Samsung in 2015. By the way, all of you must have known about LED. The QLED TV is also similar in appearance except that the Quantum Dot Display has been used in it which makes it even more enhanced. With the help of this technology, you will see the picture shown on the screen very clearly and beautiful. This technology perfectly manages the color effects of the picture, thereby increasing both the quality and capability of HDR and 4K pictures.

QLED is a layer of carbon material that lies between two electrodes, the cathode, and the anode.

What is Quantum Dot?

Quantum Dots are semiconductor particles which are of nanometer size, in fact they are made of nano crystals, it has electronic and optical properties inside it. Quantum dot is a central topic of nano technology, inside which there are ultra fine semi conductors. Quantum Dot has a purpose. To produce different colors of lights correctly. The larger particle will appear red in color and the smaller particle will appear blue. Quantum Dot is capable of producing accurate light. Because in this the particles change their shape at quantum-level velocities.

What is Quantum Dot Display?

Quantum dot started in the 1990s, at which time the quantum dot started being used. This was followed by an improved upgrade version of the Quantum Dot for displays in the early 2000s. Quantum dot naturally produces monochromatic light, similarly when color is filtered, they appear much better than white light.

Quantum dot display is a display that produces red, blue, green light using a quantum dot. Quantum dot particles are used for LED TV backlight or display color filter Quantum dot is excited by the blue light of the display so that it reflects pure colors. Do you know how light travels? Light travels through QD Layer Film and RGB Filter made of color pigments. By the way, QD color filter technology is used mostly in LED and LCD TVs.

What is Quantum Processor?

The job of Quantum Processor is to use AI (Artificial Intelligence) and Machine Learning to enhance the quality of low definition pictures up to 4K or 8K. After which the viewer gets a good experience. Quantum Processor controls backlight dimming and brightness duration very accurately. If you understand in easy language, then by scanning the lights in the picture properly, the area where there is a lack of light is also clearly visible and the light area of ​​the picture appears even more clear.

What is special about QLED TV?

QLED TVs have many different advantages. Quantum dot technology is included inside these TVs. Which provides high luminance that manages the brightness in every single part of the screen. Due to which the quality of the picture increases. Balances the high brightness of the TV screen's display and improves contrast normally. HDR (High Dynamic Range) is used to show photos and videos well. Which enhances the quality of picture and video.

The picture in QLED TV looks more clear and realistic in comparison to non-QLED TV. The color setting of these TVs is very simple compared to other TVs. QLED technology reflects each color range very well in the display. Due to which the viewer gets a very good experience.

What is OLED?

OLED (Organic Light Emitting Diode) was invented in 1987 by Ching Wan Tang and Steven Van Slyke as the first OLEDs device. It is used inside the TV display. Actually it is a layer of an organic particle which is fitted in the TV display. Moreover, it is also used to make digital displays in smart phones, laptops. It works differently from QLED. A backlight unit is required to generate light inside a QLED display, but an OLED display itself generates light, it does not require a backlight unit.

What is the difference between QLED TV and OLED TV?

People's interest is being seen more in QLED TV than in OLED. QLED technology is different from OLED technology. QLED TV enhances picture quality using Quantum dot and OLED uses Contraversial Organic Material. To improve picture quality.

QLED TVs offer higher brightness and more color range than OLED TVs.

QLED TVs last much longer than OLED. That's why you should think carefully while buying a TV because TV is not a thing to be bought every year.

OLED TVs cannot protect themselves from the problem of burn-in. Have you ever noticed the never-ending and annoying mark on your TV screen? Actually it is called TV burn-in. But QLED TVs are able to fight these burn-in problems. Quantum dot technology prevents this burn-in from the TV's display. Due to which the QLED TV picture quality does not deteriorate.

Black Level and Contrast

Contrast is the difference between the brightest and darkest parts of a picture. OLED has the ability to be completely state-of-the-art which QLED does not have so OLED is ahead of QLED when it comes to black levels.

QLED TVs block the rest of the light by dimming their LED backlight, which is called LIGHT BLEED, due to which the light does not appear the same on the screen. But if you are watching any night video and action move which has night scene then you can see some light in the dark.

Depending on the manufacturer, QLED is yet to become an OLED killer. Although QLED is a potential technology and has many amazing features inside it, it has not been able to completely replace OLED.

If we talk about today, OLED is still at number one. As you all know, OLED has been around for a long time and QLED has come a long time.


If we talk about brightness, then QLED is ahead in this matter. From QLED TVs, we can use backlights in a different way, it does not need to depend on pixels to generate lights. These LEDs illuminate the light in the right way. Quantum Dot technology is used inside the QLEDs display, due to which the quality of its picture is better and clearer than OLED TVs picture.

OLED TVs cannot generate brightness in a pure way, nor can they balance the brightness equally in every corner of the screen. QLED TVs, on the other hand, purely produce brightness and transmit the same amount of light to each portion of the screen. In terms of brightness, QLED TVs are much better than OLED TVs.

The brightness of QLED TVs is considered to be the most accurate and accurate. In which brightness is considered to be at the top of the color distribution. The QLED display shows a rollastic picture. The color combinations inside it are the best.

Colour Space

If we talk about color, then QLED TV is at the top position so far. However, OLED TVs are ahead of QLED in many things. But in terms of color and brightness, QLED TVs have held their own. Samsung company has done this medicine that QLED technology gives the best color performance.

There is no doubt that quantum dot technology makes color, brightness and brightness realistic. and offers excellent color performance. The tiny nanocrystals in QLED displays make the screen flexible and send color evenly across each portion.

Response Time

OLED TVs are faster than QLED TVs. Pixels in OLED switch very rapidly from one state to another. The faster the pixel moves, the more clearly the picture will be visible. The motion of pixels in OLED is 0.1 milliseconds and the motion of pixels in QLEDs is in 2 - 5 milliseconds. In this case, OLED is ahead of QLED.

Refresh Rate

OLED refresh rate is higher than QLED refresh rate. Refresh rate is how many frames are visible on the TV or monitor screen in one second. And it is measured in hearts. Different heart TVs are avilable in the market, if we talk about 60 hearts TV display then it will be able to do 60 FPS (Frames Per Seconds). And if we talk about 120 hearts, then it will be able to do 120 FPS. In general, TVs with 120 hearts are expensive. Hence their refresh rate is also high. Refresh rate matters a lot while gaming.

Viewing Angle

If we talk about the accuracy of colors, then OLEDs display performs much better. And on the other hand, when it comes to QLEDs display, the viewing angle is more accurate in OLED. QLED displays look better than OLED displays from the front, but changing the angle changes their color accuracy and makes the picture look different.

There is no such problem in OLEDs display, even if you change your viewing angle, you will not see any difference in the picture. There is no change in the picture even when the OLEDs display is viewed from an angle above 84 degrees. The color accuracy of the picture remains the same as it looks from the front. You can see from any angle, whether it is up or down or left, right, the same picture will be seen from every angle. The OLED display is ahead in this regard, ahead of the QLED display.

(Which is better QLED or Crystal UHD?)

What is Crystal UHD?

Crystal is the full form of UHD (Ultra-High Definition) which means the display range of the TV, which offers 4k resolutions from 3840p 2160p.

QLED TVs offer a much better experience than Crystal UHD TVs. Provides 4k resolution and more color coverage. QLED technology uses LED backlight to project onto a quantum dot. In which more brightness and accurate color brightness is provided.

What is QLED TV?

QLED TVs are QLED 8K HDR Smart TVs that offer an infinity screen and 8K picture quality. With this, QLED TVs can comfortably run movie apps like Netflix, Disney+, and Amazon Prime, and sport applications.

With this technology, you will find the sound of your TV the same in every corner and you can even give instructions to the TV with your voice.

What is QLED Display Features?

Quantum dot is used in QLED technology which are semiconductor particles which are very small in size. They are in the size of nanometers, whose job is to see all the colors of light properly.

- Incorporates Quantum Dot technology inside QLED which efficiently manages the brightness in each part of the screen thereby enhancing the picture quality.

HDR (High Dynamic Range) is used to make the picture look better. Shows a more realistic picture view in QLED TVs than in non-QLED TVs.

- During quantum dot manufacturing, many semiconductors are used which work to enhance the quality of the picture, namely PbSe, PbS, InAs, InP, CdSe, CdS, etc.

Backlight units are used to illuminate the light. With the help of backlight, the light is emitted and passed through many plates. Which creates a picture on the screen.

To show a color full picture on the screen, 6 different layers are applied behind the screen so that the viewer can see a clear and clean image. There are 6 layers inside the TV's display.

1. Backlight Panel - The backlight panel is used to show the image. Backlight is a form of light. LCD / LED does not produce light itself, so in that case they need a backlight panel to make the image on the screen.

2. Reflector sheet - Reflector sheet is an optical film that runs inside the TV, which is reflected and shown on the screen.

3. Polarizing Filter - It is mostly used in cameras but now it has started being used in LED TVs as well. Its main purpose is to manage the natural lights of the environment. You must have noticed that when the brightness of the sky is high, it reduces the brightness of the object. Therefore it is used to manage this defference.

4. TFT Array - TFT full form is Thin Film Transistor which is used in LCDs and LEDs TV display. It increases the stability of the picture by reducing the crosstalk between the pixels.

5. Color Filter Glass - This is a glass glass. Its job is to reduce the extra light falling on the screen.

6. Quantum Dot Color Filter - This filter works. To manage the color to reach the place of need in the picture.

(What is QLED Display Advantages?)

1. Color Accuracy

One advantage of QLED displays is that they produce accurate and more varied colors. Quantum dot particle generates color based on its size. QLEDs display show better colors and realistic picture as compared to LCDs display.

2. Higher Brightness

When Quantum dot technology is used in LCD, it produces more light than before. Nanocrystal particles have more optical properties than the crystals found in LCDs. For this reason, nanocrystal particles produce more brightness than LCD crystals.

3. Improved Contrast Ratio

QLED Quantum dot technology is KPR based, due to which QLED can produce more contrast ratio as compared to LCDs. Quantum dot controls brightness and light well, due to which QLED display can generate darkness.

4. Thin, Flexible and Lighter Display

Due to Quantum Dot Technology, the QLED TV screen is extremely thin and flexible, making it very light in weight. Before QLED TVs, OLED TVs used flexible displays. Based on this, the later QLEDs TVs started using more flexible, lighter and thinner displays than OLED TV displays, which increases the quality of the picture more than before.

5. Long Life

If we talk about their life, then the life span of QLED is more than other TVs. QLEDs can be used for a longer time than OLEDs. OLEDs are more prone to spoilage from exposure to water or moisture because they use organic carbon for color, which reduces the life of the TV when exposed to moisture. On the other hand, QLED TVs do not have to face so much problem. QLEDs TVs are more durable than OLEDs TVs.

6. Power Efficiency

QLEDs TVs consume less energy. LCD's Tulma is very good power efficient. Large crystals of LCD use more energy to make the combination of the locker, on the other hand, Quantum dot technology in QLEDs TVs uses smaller crystal particles and focuses more on only the color that is needed, so that a lot. All the energy is saved.

 What are QLED Display Disadvantages?

- One disadvantage of QLED display is that it cannot achieve low contrast ratio compared to OLED display. The backlight inside it prevents deep blacks.

- A visual angle response of QLED is less as compared to OLED. When we change the viewing angle of the TV, then we see disparities in the picture. Due to which the quality of the picture decreases.

- The response time of QLED display is less than that of OLED display. OLED changes frame in 0.1 milliseconds while QLED display changes frame in 2 milliseconds.

All the problems with LCD are inside QLEDs. Limited contrast ratio, slow pixel processing. All these problems are not seen in OLEDs displays.

- QLEDs display cannot produce light on its own like OLEDs display, for this it uses backlight units

QLEDs display have lower blue light purity than OLEDs displays. Due to the small size of the quantum dot, blue light takes longer to perform.
