Classification: CPC G | IPC G

Claim 0:
1. A display panel, comprising:
a data compression unit configured to acquire a plurality of first compensation data and a common parameter, and further configured to compress each of the first compensation data into second compensation data according to a preset compression rule based on the first compensation data and the common parameter; and
a data decompression unit configured to acquire a plurality of the second compensation data and the common parameter, and further configured to decompress each of the second compensation data into the first compensation data according to a preset decompression rule based on the second compensation data and the common parameter, wherein:
a bit width of the second compensation data is smaller than a bit width of the respective first compensation data; and
a difference between each of the first compensation data and the respective second compensation data is equal to the common parameter,
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.
