At present, using mini‐LED as the backlight with Local Dimming control algorithm is mainstream HDR program in LCD products. Currently Local Dimming still exists halo effect and other issues, this paper designs a Local Dimming algorithm, and uses FPGA to verify the algorithm, optimize halo, flicker and other issues. After halo effect test verification, halo effect is excellent.
