Title: Wanglei Han - Innovator in Display Technology
Introduction
Wanglei Han is a notable inventor based in Fremont, CA (US). He has made significant contributions to the field of display technology, particularly in addressing issues related to pixel aging and burn-in effects.
Latest Patents
Wanglei Han holds a patent for a "Display with optical sensor for brightness compensation." This innovative display technology includes pixels, such as light-emitting diode pixels, that are susceptible to aging effects, commonly known as burn-in. To mitigate visible artifacts caused by burn-in during the display's operation, compensation circuitry is utilized to adjust image data. An optical sensor is integrated behind the pixels to directly measure pixel brightness levels. This optical sensor gathers data during burn-in testing operations, where pixel groups, including both high-usage and low-usage pixels, sequentially emit light. The data collected helps characterize pixel aging and compensates image data to reduce visible artifacts. Additionally, the optical sensor collects data during global brightness testing operations.
