‘Unrivaled Color Expression’ QD-OLED, Superior Viewing Angles
Exceptional viewing angles proven by UL ‘QuantumView’ validation… Luminance maintenance over 60% even at 60-degree angle
□ UL Solutions completes viewing angle evaluation for the entire ‘QD-OLED’ lineup
□ Luminance stays above 60% with almost no change in color coordinates at 60-degree side view
□ QD-OLED becomes essential for dual/pro-reference monitors to avoid luminance drop and color distortion
□ Samsung Display: “Quantum Dots exhibit a ‘Lambertian-like’ emission pattern, scattering light widely for superior viewing angles”
□ Expansion of self-emissive monitor market from gaming-focused B2C to high-precision B2B sectors


Samsung Display’s QD-OLED, known for having the best color expression among existing displays, has once again been recognized for its exceptional picture quality by proving superior viewing angles.
The company announced on the 22nd that its QD-OLED for TVs and monitors has recently completed the ‘QuantumView™’ validation by UL Solutions, a global safety science leader. The ‘QuantumView™’ evaluation measures changes in luminance and color coordinates based on the viewing position (moving in 10-degree increments from the front up to a 60-degree point). The evaluation results for the entire QD-OLED lineup showed that at a 60-degree side view, the luminance maintenance rate remained above 60% compared to the front, and the color coordinate change was almost negligible at 0.012 or less. For typical LCDs, the luminance maintenance rate at a 60-degree angle drops below 20%, and the color coordinate change can reach up to 0.025—about twice the variance seen in QD-OLED.
“Viewing angles have always been a key factor in selecting a TV, considering environments where multiple people watch together in a living room,” said a Samsung Display representative. “Recently, as usage patterns change—such as the increased use of dual or triple monitors and professional reference monitors for collaborative work—the demand for wide-viewing-angle QD-OLED monitors is also rising.”
The company attributes QD-OLED’s superior viewing angle characteristics to its unique top-emission structure and the ‘Lambertian’ emission property of Quantum Dot materials. Light typically has directionality, causing brightness or color to change depending on the viewing angle. However, ‘Lambertian emission’ refers to an optical property where light is emitted uniformly in all directions, providing consistent brightness regardless of the angle.
“In a QD-OLED, Quantum Dots absorb blue OLED light and re-emit it into red and green wavelengths. These nanometer-sized particles don’t just convert color; they exhibit a Lambertian emission pattern where light spreads widely in a spherical shape,” the company explained. “Unlike other large OLED technologies, QD pixels directly create vivid, high-purity colors at the front, simultaneously improving color accuracy and light efficiency.”
Based on these superior wide-viewing-angle and color reproduction characteristics, Samsung Display is expanding its OLED monitor market beyond the gaming-centered B2C market into B2B areas with high demand for high-precision displays, such as video/graphic professionals, content creators, and financial traders. Recently, ASUS and Dell Technologies launched their professional monitor lines—ProArt and UltraSharp, respectively—featuring QD-OLED, receiving positive market responses. Other manufacturers like Acer, Lenovo, and MSI are also expected to introduce professional monitor lineups.
“The ‘QuantumView™’ validation objectively proves that QD-OLED is a technology that provides consistent picture quality across diverse viewing environments,” said Jung Yong-wook, Vice President and Head of the Strategic Marketing Team at Samsung Display. “By collaborating with global brands using QD-OLED, which combines outstanding color expression with wide viewing angles, we will provide consumers with the best possible viewing experience large displays can offer.”
