Samsung Display’s QD-OLED Receives UL Verification for Viewing Angle Performance

Samsung Display announced today that its QD-OLED panels for TVs and monitors have received verification from UL Solutions, a global leader in applied safety science, for their viewing angle performance under the ‘Quantum View’ standard.

‘Quantum View’ is a verification program that evaluates changes in luminance and color coordinates as the viewing angle shifts from the front in 10-degree increments up to 60 degrees. According to the assessment results, Samsung Display’s QD-OLED panels maintained above 60% of front-facing luminance even at a 60-degree angle, while color shift remained below 0.012, indicating minimal change.

In comparison, LCD panels are known to experience luminance degradation to below 20% at 60 degrees, with color shift recorded at a maximum of 0.025, approximately twice the level observed in QD-OLED.

A Samsung Display official explained that viewing angles have long been a key factor in TV selection due to shared viewing environments in living rooms and the preference for larger screens. As usage patterns continue to evolve, with increasing adoption of dual and triple monitor setups as well as professional reference displays where multiple users view the same screen simultaneously, demand for wide viewing angle QD-OLED monitors is also growing.

According to the company, the superior viewing angle performance of QD-OLED is enabled by its proprietary front emission structure and the inherent optical characteristics of quantum dots. While light typically exhibits directional properties that can cause variations in brightness and color depending on the viewing angle, quantum dots exhibit a ‘Lambertson-like’ emission pattern, emitting light evenly in all directions.

In QD-OLED, quantum dots absorb blue OLED light and re-emit it in red and green wavelengths. During this process, the nanometer scale quantum dot particles not only convert color but also emit light in a spherical pattern, forming a Lambertian-like emission distribution. In addition, unlike other large OLED technologies, QD-OLED generates pure and vivid colors directly from the front surface, enabling both high color accuracy and optical efficiency.

Building on its strong viewing angle and color reproduction characteristics, Samsung Display is expanding its OLED monitor business beyond the gaming focused B2C segment into B2B markets with high demand for precision displays, including video production, graphic design, content creation, and financial trading.

Recently, ASUS and Dell Technologies launched professional creator monitors equipped with QD-OLED, including the ProArt and UltraSharp series, respectively, which have received positive responses in the market. Other manufacturers such as Acer, Lenovo, and MSI are also planning to introduce professional monitor lineups featuring QD-OLED.

Brad Jung, Vice President and Head of the Large Display Marketing Team at Samsung Display, stated,

“Through QuantumView verification, we have objectively demonstrated that QD-OLED is a technology capable of delivering consistent image quality across a wide range of viewing environments.”

He added, “We will continue to expand collaboration with global brands and lead innovation in picture quality in the large-area OLED market.”
