OLED stands for Organic Light Emitting Diode, it is an advanced form of previous LED lighting. In brief, this technology does not need a backlighting system, because each pixel is individually lit. That’s the reason why is it such a beautiful display for, thin and high resolution display panels featuring rich colors and brightness on a pixel-by-pixel criteria, and that results in a more clear and attractive picture quality. QLED means, Quantum Dot Light Emitting Diode. Quantum dots are microscopic Nano crystals and these are very good conductors and allow supply of light to each individual pixel directly used in an LCD display. Same as OLED, it also does not rely upon backlighting system too.

Difference between QLED AND OLED:
QLED is all around a different technology. Quantum dots give coloured light and that can be variable according to the size of quantum dot structure and magnitude of energy being passed through it.
QLED is offers much higher brightness than OLED panels, ranging between 1,500 to 2,000 nits (In lighting study, the nit is a unit to specify the brightness of a cathode ray tube or liquid crystal display computer display. One nit equals to one candela per square meter) with good and clean colour accuracy, whereas OLED panels lasts out under 1000 nits.
Therefore practically it makes QLED technology better option for HDR, which seeks a wide range of rich colours and correct contrast.
QLED vs OLED: Which is better?
Our team suggests that currently QLED is the best technology to explore the benefits of HDR and 4K display, and that’s what the future of display is in the coming years. QLED consumes less energy than OLED technology, and thus makes it cheaper.
Still we cannot deny the fact that we are still not certain that which technology will rock the markets in coming future. But the first look of QLED TVs is very interesting and consumers are also showing the interest in it. Hence, rather than commenting on what technology you should go for, we will wait and see how this year goes for the QLED televisions and suggest you better on that data.
