OLED AND QLED: how TV technology works

The technology OLED and QLEDare the most advanced versions for television screens available on the market.

For those who are planning to purchase these high end gadgetsthey must take into account their differences and which one suits their preferences.

There are of different prices, sizes and qualitieswhich may include more concepts such as UHD, 4K, HDR, among others. Likewise, they can incorporate functions of the Smart TVsuch as Android TV and Chromecast.

This technology was developed by Samsung at the beginning of 2017, its acronym in English is Quantum Dot LEDwhich stands for Quantum Dot LED.

Referred to in the trade as QLEDis the advanced version of the conventional LCD-LED technology that came to improve the feedback color and the screen shapesince it added to the televisions a thin layer of quantum dots, between the LED feedback and the LCD screen.

This new addition purifies the light coming from the LEDs to obtain a better coloration, more alive, saturated and giving brighter screen.

The name of this technology comes from the acronym in English Organic Light Emittingwhich stands for Organic Light Emitting and is fundamentally different from conventional LEDs and LCDs.

the pixels emit their own light on a televisionwhich means that an LCD screen is not necessary to display the image, but instead there are three micropixels in each one that correspond to the matrix of red, green and blue colors.

OLED have better image quality, contrast and portraits with deep blackswhich is important for scenes shot at night or in low light.

In a conventional LED TV, the light-emitting diodes never turn off completely, so they use dark grays to simulate black.

like the pixels OLED controlled individually, they also change color quickly. This is important for video game, sports either action movies. Plus, they offer a wider range of viewing angles, and because they don’t have an LCD screen, the TVs are thinner, making them easier to mount on the wall.

OLED panels are extremely thin and lack a separate LED backlight, so unlike QLEDs they require significantly less power to run, around a 40% less in equal size.

On the other hand, televisions QLED have higher brightness thanks to the quantum dot filter. That makes them better for rooms with higher levels of ambient light. And they are usually cheaper.

And in terms of size, if what you are looking for is a large screen, in this case the QLEDsince there are currently 98 inches unlike the 88 of the OLEDs.
