Samsung reveals QD-OLED screen with 1000 nits of brightness – beautiful, fresh, pure, HDR display, much brighter than before

OLED TVs still don’t have much of a choice in the market, led by LG and closely followed by Sony and the rest of the brand, but the competition may soon become more intense when the biggest giants like Samsung are jumping in. too with QD-Display technology that is the ultimate punch from the initial disclosure This panel is outstanding in terms of brightness level and the range of colors that can be displayed.

In a review by Société Générale de Surveillance, or SGS, Samsung’s QD-Display meets True Color Tones, Pure RGB Luminance, and Ultrawide Viewing Angle, demonstrating accurate color. natural realism and bright in every angle


Rough example of QD-OLED structure

QD-Display is a combination of Quantum dot technology and OLED, or you can call it “QD-OLED” screen. Basically there are still organic compounds. and can emit light on its own But the light emitted is blue, not the familiar red, green and blue.


Compare the differences between WOLED and QD-OLED.

Reasons for using blue light This is because light waves in this range have the highest energy. It shines through nanometer-scale semiconductor particles. The dotted nature is the origin of the name Quantum dot. Such a substance has a fixed size. Small and large are not the same It acts to block light at different wavelengths until it produces the desired color. This allows for a more pure color. because of disturbance and less adulteration It also has a long service life. Difficult to burn in Because the blue OLED layer has up to 3 layers ever.


Rec. 2020 color gamut is 90% real as claimed by Samsung, based on testing by Linus Tech Tips.

Samsung states that the QD-Display has 90% Rec. 2020 color gamut coverage according to ITU standards, or 120% of the DCI-P3, while most TVs have 70% or lower, even the high-end OLED G1. LG’s device last year was only 75%.

While brightness has long been the weak point of OLED TVs, QD-Display has now tightened the gap with LCD panels that use LED as a backlight. with a maximum brightness of 1000 nits, when combined with the strength of the original contrast ratio Therefore, HDR can be displayed much more realistically than before.

Another advantage of applying quantum dot technology to OLED is that the increased brightness of white light It doesn’t compromise the brightness of red, green and blue light like in WOLED.

QD-Display enters production line which will begin to be used in practice within this year And it is likely that Samsung will sell the panel to other brands for use other than its own use, as well as Sony, which currently uses LG’s OLED panels, which will give consumers a wide variety of OLED TVs that are attractive. Definitely more interested in the market.
