Claim 15:
16. A compensation data compression method for a display panel, comprising:
acquiring a common parameter and a plurality of first compensation data; and
calculating a difference value between each of the first compensation data and the common parameter to obtain second compensation data,
wherein, a bit width of the second compensation data is smaller than a bit width of the first compensation data,
wherein the display panel comprises a driving transistor, and the first compensation data comprises mobility compensation data of the driving transistor; and
wherein the common parameter is acquired by a preset detection method, and the preset detection method comprises:
writing, in a non-compensation state of the display panel, different input grayscales into a preset area of the display panel in a time-division way;
detecting a brightness of the preset area to obtain a plurality of input grayscales corresponding to different brightness;
acquiring an output grayscale corresponding to each of the input grayscales in the non-compensation state, according to the plurality of input grayscales corresponding to different brightness;
acquiring a plurality of target input grayscales corresponding to different brightness;
acquiring target compensation data according to the plurality of target input grayscales and a plurality of output grayscales; and
subtracting a preset value from the target compensation data to obtain the common parameter.
