OLED, QLED, LCD, and Micro LED: What’s The Difference?

You might think that OLED, QLED, LCD, and Micro LED have the same features and benefits. But it’s not true. All of them have their own advantages and disadvantages that make them different from each other. If you want to learn more about them, read the article further to understand what they are and how they are dissimilar.

QLED (Quantum Dot LED)

QLED(Quantum Dot LED) is not similar to OLED, as it is an LCD TV that has LED backlighting. Moreover, the Quantum Dots are nanoparticles that help to improve the brightness and color of the LCD panel. It is an innovative and unique method compared to traditional backlighting because it helps to increase the OLED features without overpowering the pixels with higher light.

In this TV, the LCD matrix plays the role of shutters to prevent the light from bleeding into the colors. Plus, it filters the light to reconstruct the color on display. It is a modern and complicated method that companies like Samsung have made for providing a high-quality display to the users. Yes, it can produce bit brightness in some devices but don’t reproduce the dark and light tones like the OLED.

You might be wondering why you need to choose QLED when OLED offers you the superiority of imagining. A consumer may choose QLED over OLED because of three reasons: size, color, and brightness. OLED is hard to manufacture for bigger screens. Not to mention, QLED can also produce a much higher percentage of light compared to OLED. The greater amount of light is the result of the backlit panels. Another benefit of using QLED is an accurate color quality certified by the VDE Institute.

OLED (Organic Light-Emitting Diode) TVs

OLED or Organic Light-Emitting Diode was created by LG in 2013. Later in 2017, Sony introduced OLED TVs with much better upgrades. On the other hand, Vizio introduced its first OLED TV in 2020, and Panasonic has made its first OLED in2021. Some other companies in the world are also manufacturing OLED TVs, but they are not available in the US market. These devices are electroluminescent, which means when a pixel is sent, it emits an electrical charge; its light depends on the strength of the signal. The stronger the signals, the brighter the pixels will be.

An excellent advantage of these TV is that when a pixel is not charged, the OLED can remain completely black. This device also has the potential to control the light of each pixel; the bright sections of the image can be easily pinpointed.There are also no blooming effects on the LED displays. However, it is not as good as you think. OLED can become brighter similar to the LEDs, and they have the potential for burn-in. Lastly, they have a higher price tag than the LED televisions.

MicroLED TVs          

You may have been hearing about these TVs from Samsung for several years. Now, they have launched three models of MicroLED in 2021. This is the first TV display innovation to hit the consumer market after ten years of introducing the SonyXEL-1. In this technology, each pixel comes with three microscopic LEDs that emit brightness and color. As the device controls every pixel separately or independently, it can be turned off to make it completely black, similar to OLED without the LCD layer for light.

Samsung has combined the advantages of both LED’s brightness and OLED's black level without causing problems like burn-in. However, of course, like any new innovation and technology, these TVs will be undoubtedly expensive for some years. The Micro LED of Samsung, The Wall, is one of the sleekest and biggest TV in the world. Samsung has launched Micro LED in the sizes of 110, 99, 88, and 76 inches.


This is an old-school flat panel TV, LCD, which uses a liquid crystal display as a screen. LCDs don’t produce their own light. They rely on the light source present behind the LCD screens so that you can see the picture. Besides that, an old-generation LCD uses CCFLS or cold cathode fluorescent lamps to produce the necessary light. It helps to emit uniform lighting but makes the TV bulky and thick. One of the drawbacks of the LCD TVs is they don't get black. Some great models have a bit more ability to achieve the black screen than others. But in the LCD, getting a really dark grey screen is not possible.

Many people think that LED TVs are far better technology than LCD. But little do they know that the only difference between them is the backlight. You should know that LED TV is similar to the LCD TV but has a different backlight type. LED TV uses LED edge lights or LED panel array to emit the light for the LCD screens. This helps the LED give longer-lasting backlights, uniform lighting, lower energy consumption, thin TV cabinets, and less heat production.

Bottom Line

Although manufacturers use OLED in monitors, smartphones, and televisions, there are other alternatives. QLED is Samsung's technology that has the ability to offer larger display sizes not susceptible to screen burn, longer lifespan than OLED, and brighter than any other TV innovation.

On the other hand, MicroLED is pretty similar to the OLED when it comes to pixels. But they have excellent resolution images with higher luminance. MicroLEDs have taken over the market until another technology comes into the market. Lastly, LEDs are simply the base of all these three TVs with lesser features and specs.

So, if you are thinking of purchasing any of these, then you should go ahead. But if you are confused about which one will be suitable for you, then Illusive Automation can help you make the decision.
