Samsung Display has completed certified viewing-angle verification for its full QD-OLED lineup. Samsung Display said on Tuesday its QD-OLED products for TVs and monitors completed the 'QuantumView (QuantumView™)' evaluation by global safety science company UL Solutions.

QuantumView is a viewing-angle verification evaluation that measures changes in luminance and color coordinates by moving 10 degrees at a time from the front, up to 60 degrees. Across the full QD-OLED product range, luminance retention at a 60-degree side angle was more than 60 percent versus the front, and the change in color coordinates was 0.012 or less. A typical LCD sees luminance retention fall to 20 percent or less under a 60-degree viewing-angle condition, and the change in color coordinates can reach as high as 0.025. That is about double the color-coordinate change compared with QD-OLED.

A Samsung Display official said viewing angle has long been an important factor in choosing a TV, given living-room viewing environments where multiple people watch together and consumer preferences for large screens. Demand is also rising for wide-viewing-angle QD-OLED monitors as usage patterns change, including more use of dual or triple monitors or professional reference monitors and more cases where multiple people review joint work on a single monitor, the company said.

The company explained that these QD-OLED viewing-angle characteristics stem from its front-emission structure and the Lambertian emission characteristics of quantum-dot material. Lambertian emission is an optical characteristic that emits light uniformly in all directions, delivering the same brightness regardless of viewing angle. The company said: "In QD-OLED, quantum dots absorb blue OLED light and re-emit it in red and green wavelengths. At this time, the quantum dots, which are minute particles on the nanometer scale, do not only convert color but also show a Lambertian emission pattern in which light spreads widely in a spherical form."

Samsung Display is expanding the OLED monitor market beyond the gaming-focused B2C market to B2B sectors with high demand for high-precision displays, such as video and graphics professionals, content creators and financial traders, based on wide viewing angles and color reproduction characteristics. The company added: "Unlike other large OLED technologies, QD pixels directly create clear, high-purity color from the front, so it can raise color accuracy and luminous efficiency at the same time."

ASUS and Dell Technologies have each launched professional monitors, 'ProArt' and 'UltraSharp', equipped with QD-OLED and are receiving market response. Acer, Lenovo and MSI are also set to introduce professional monitor lineups.

Yongwook Jung (정용욱), head of strategic marketing at Samsung Display, said: "Through QuantumView verification, we have objectively proven that QD-OLED is a technology capable of providing consistent picture quality in various viewing environments." He said: "With QD-OLED that has a wide viewing angle on top of outstanding color expression, we will work with global brands to provide consumers with the best viewing experience that large displays can offer."
