SGS certifies Samsung’s QD show for colour accuracy, RGB rendering, and ultra-wide viewing angles

Samsung has always been at the forefront of display technology, and you may have heard of its panels used in several categories of products, mostly on televisions and the large number of cell phones. Well, today Samsung Display announced that its QD (Quantum Dot) display has been certified by SGS in three criteria, which promises that these displays offer improved color accuracy, RGB rendering and wider viewing angles.

The three certifications obtained are:

  • True color tones
  • Pure RGB luminance
  • Ultra-wide viewing angle

“As the video content industry, production technologies, platforms and communication infrastructures grow rapidly, the demand for high-quality content is growing rapidly,” said Ho Sun, head of strategic marketing for Samsung Display’s Large Display Division
“QD-Display is the answer to this demand and offers consumers a new standard for displaying high-quality content in the highest picture quality.”

The True Color Tones certification is awarded to the display based on tests with the BT.2020 (also known as rec.2020) and the DCI-P3 color spaces. For the former, the QD panel was able to achieve 90 percent coverage, a figure more than for existing products, and for the latter, it achieved 120 percent of the defined color volume of the criteria.

Samsung Display mentioned that the color space of the existing TV display rarely exceeds 70 percent of the BT.2020 standard and the color volume tends to drop below 100 percent.

Next, QD Display was awarded the Pure RGB Luminance Certification, which highlights its ability to express red, green and blue colors without additional compensating luminance. Certification is granted when the total sum of luminance for each RGB primary color is equal to or greater than the luminance value of white produced by the combination.

The QD display’s white luminance is reportedly 1,000 nits and the combined values ​​obtained from testing by SGS were estimated to be equivalent.

In general, displays add white pixels to increase luminance, which results in the RGB pixels being lower in brightness in comparison, ultimately resulting in darker colors on the screen – a strict no to accuracy.

And finally, for the Ultrawide Viewing Angle certification, the image quality of the display was analyzed by multiple viewers from different positions. The internal evaluation by Samsung showed that a 65-inch television, WOLED and LCD showed a decrease in frontal luminance to 53 percent and 35 percent respectively when viewed from a 60-degree angle. On the flip side, the QD display only showed a 20 percent decrease, while maintaining 80% of the frontal luminance.

These improvements will continue to find their way into consumer products as Samsung Display continues to mass produce the QD display. It added that it is working with several customers to bring this technology into products that will hit the market in 2022.
