Publication number: 20260190648Abstract: A display device is provided showing, relative to conventional devices, improved performance after thermal degradation. The display device provides a reduced difference between luminance of a degraded device and luminance of a non-degraded device at extreme viewing angles, where this difference cannot be fully addressed by front compensation. Improvement over display devices having subpixels disposed in a regular two dimensional array is accomplished by offsetting a portion of subpixel light-emitting areas along a critical dimension within the plane of a flat screen relative to corresponding subpixel lenses, a design that compensates for shrinkage in subpixel light-emitting areas in degraded displays.Type: ApplicationFiled: December 15, 2025Publication date: July 2, 2026Inventors: Yong-Ku Lee, DaeHeung Lee, ARa Yoon, JinWoo Hong, SeWan Oh, YoungBok Lee
