The annual Consumer Electronics Show (CES) has always been a platform to showcase new technologies. At this year’s CES for TVs, it was QD-OLED, a new display technology that’s set to arrive this year. In the past decade, we’ve gone from LCD, to lead You And QLED, and now there’s QD-OLED. Here we explain what QD-OLED And how does it actually work.
What is QD-QLED?
QDs – or quantum dots – are actually tiny semiconductor nanocrystals. These nanocrystals glow in a specific color and are activated by light. What’s next are brighter, natural and accurate images in color reproduction. QD-OLED takes existing OLED technology and improves it with the help of quantum dots. OLED displays have always been much better than LCD displays and QD-OLED makes it a lot better.
How did it happen QD-OLED Display Work?
samsung QD- is one of the main driving forces behind OLED displays. And the company explains exactly how it works. A QD display is a self-luminous display and consists of a TFT layer – the electronic circuit that controls the light-emitting layer – a light source that emits light, and a QD light-emitting layer that produces color using the emitted light. Represents light source. QD display uses the blue color, which has the strongest light energy, as the light source to achieve a relatively bright brightness. The blue light generated by the light source of the QD display has very high color purity, and the red and green QDs that receive the blue light and generate color, also produce color light with high color purity. All of these combine into a QD display to deliver natural and bright colors on the TV.
What are the advantages of QD-OLED?
Quantum dots can achieve high levels of brightness and are also quite stable. What this will do is prevent the TV from suffering any kind of ‘burns’ on the display. The QD-OLED will also ensure that the colors don’t get washed out too much. The QD display enables a high contrast ratio of 1,000,000:1 due to the expression of deep blacks. A ‘traditional’ display has a contrast ratio of 100,000:1. Samsung claims that in the visible spectrum, short-wave blue light with wavelengths between 41 nm and 455 nm is known to affect sleep by increasing eye fatigue and with it suppressing melatonin secretion. Short wavelength and strong energy. What the QD-OLED does is that it optimizes blue light exposure to ensure a more comfortable viewing experience.
How much will a QD-OLED TV cost?
The price has not been disclosed, but we expect it to be priced much higher than the usual OLED and LED TVs. Samsung and Sony plan to launch TVs with this new technology sometime in 2022. However, the prices and launch dates are still not disclosed.
