This invention discloses a new system approach to compensate the brightness non‐uniformity of

local dimming display. An accumulator is in between GPU and display panel to keep accumulating

the loading of each zone. When the compensation is triggered, the accumulated loading is feedback

to GPU, and then stress the zones with lower accumulated loading to the same level of zones with

higher accumulated loading. In the end all the zones have the same accumulated loading.
