28‐2: Addressing Image Retention for MLED LTPS COG: A Compensation Method Based on Thermal Diffusion, Boundary Search, and Frame History

MLED technology enhances display performance with superior light output, contrast levels, and color rendering accuracy. However, MLED LTPS chip‐on‐glass (COG) must address image retention, resulting from decreased brightness in the LED red channel due to high temperature. This paper presents a compensation method, incorporating thermal diffusion, boundary search, and frame history. The approach is implemented on FPGA and successfully integrated into mass‐produced MLED displays.
