The latest confirmation has arrived: Samsung Display Published a page dedicated page for QD-OLEDs (link in SOURCE), screens made of blue OLED emitters with quantum dot. After Previews of The Korea Economic Daily And Press release issued by UBI Research, Thus closing the circle with a perfectly official official source. Obviously Samsung is not talking about display TV, to be understood as a complete and finished product, but as a manufacturer of panels it limits itself in portraying the advantages of technology (Samsung Visual Display Division divisions make televisions for Samsung Electronics).

Let’s start with the name: Samsung never mentions the word OLED, which is not surprising when you consider it Type of communication The Korean giant recently implemented. Calling for new technology QD-Display, Summary of Quantum Dot Display. We have already learned the structure of screens: everything starts Organic blue emitters capable of illuminating their own light and turning every pixel on and off.

To this layer, “Blue self-illuminating layer“,”QD layer“An additional layer of red and green quantum dots. Some blue light simply passes through, while the rest passes through the QD layer, absorbing it and re-releasing the red and green components in pure form, giving you all the RGB primary color components, which Samsung claims Decreased levels of blue light, which is harmful to the eyes: Strictly speaking, it goes from 20-25% of a traditional LCD display to 12-14% of QD-displays. So it is 40 to 50% less.

With regard to color reproduction, QD-displays aHigh purity for all color elements, From the blue of OLED emitters to the red and green obtained by quantum dot. This feature is a Extensive color volume (here we explain what it is and what it is for): You can reachBT.2020 normalizes and measures 80% of the color space according to the ICTCP standard. Color volume “normalizes” but means to connect its coverage to the peak of the specified brightness for that particular screen.

The use of organic components also makes it possible to reduce the response times of the panels (not to be confused with the latency in signal processing, i.e. input lag), which is common to all OLEDs. The need to control liquid crystals reduces the responsiveness of LCDs in this regard.

Another improvement that is expected and clearly seen is the ability to spread light in all directions. This feature, when translated into simple words, indicates that QD-displays have a Broader viewing angle than LCDs. If you position yourself at a 60 degree angle from the center, traditional LCDs can only display less than 40% of maximum brightness, while QD-displays retain more than 70%.

The Technology for reducing reflections Samsung Display guarantees excellent intelligence even in difficult situations, such as direct sunlight coming from a window or artificial sources affecting the screen (these types of filters have already proven to be very effective on Samsung QLEDs).

QD-displays will have an A Ultra HD resolution They can depend on one Very wide dynamic range. The covered range is in between 0.0005 cd / m2 – Knits for black This one The peak of light is equal to 1,000 cd / m2 – nits for white. The data related to blackout should not be misleading: it is the same value required to obtain Ultra HD Premium Certification 540 cd / m2 – when combined with a peak of nits. In fact it refers to complete black.

This peak is usually higher than that associated with OLED TVs but no data showing the white area. In the diagram above, the conventional display as a scale is very high black (0.15 cd / m2 – nits) and has a peak of 3,000 nits, which is usually not very useful for video mode value. In real life, it is stored for short moments.

However, if the announced 1000 nits were associated with 10% white of the screen, the QD-displays would actually be brighter than the OLEDs that stand out in this sense. LG G1 (recently tested), I Sony A90J (review here) ei Panasonic JZ2000 (Presi).

Samsung Display later lists another quality that has long been known for OLED screens: the ability to control the emission of light in individual pixels allows you to accurately define light and dark, avoiding problems such as dimming of light. When bright elements combine with very dark areas (light from the first pollutes the black) it is called “blooming” which can be created on the LCD.

Samsung closes by talking about the contrast ratio: when a good white peak approaches an absolute black, the difference that the viewer sees is very high, even though the size of the white peak is actually smaller than LCD screens. This feature is now a recognized feature of all OLED TVs, and QD-displays are no exception.

Compared to WRGB LEDs, the brightness of the screen should have better color saturation because the volume of color (as evidenced by this trend) is directly related to the RGB structure of the pixels, which is theoretically wider compared to other OLED TVs. Less brightness but more saturated colors will make the eyes look brighter Because of the so-called Helmholtz-Colerosh effect.

No further details are available at this time: Submitting a page to the latest technology is a clear indication of the accuracy of all recently circulated information. Other news may come in the months that separate us From CES 2022, Stage We will definitely see the debut of the first QD-display televisions.
