Abstract
A display driving method, compensation data compression and decompression methods and devices, a display device and a storage medium. The compensation data compression method includes dividing a display panel into at least one region; determining a reference value according to first compensation data of each pixel unit in each of at least one region; performing a computation on the first compensation data and the reference value to obtain corresponding second compensation data. The storage bit length of the second compensation data is shorter than the storage bit length of the first compensation data.
Claims19
A compensation data compression method of a display panel, comprising:
- dividing the display panel into at least one region;
- determining a reference value according to first compensation data of each pixel unit in each of the at least one region;
- and
- performing a computation on the first compensation data and the reference value to obtain corresponding second compensation data,
- wherein a storage bit length of the second compensation data is shorter than a storage bit length of the first compensation data;
- and
- the dividing of the display panel into the at least one region comprises:
- dividing the display panel into a plurality of regions,
- obtaining reference values of two adjacent regions respectively, subsequent to dividing the display panel into the plurality of regions;
- and
- merging the two adjacent regions into one region, in a case where a difference value between the two reference values is within a preset threshold range.
A compensation data decompression method of a display panel, the display panel being divided into at least one region, each region comprising a plurality of pixel units,
- for each of the plurality of pixel units, the method comprising:
- obtaining initial compensation data of the pixel unit, wherein the initial compensation data comprises a reference value corresponding to a region where the pixel unit is located and second compensation data corresponding to the pixel unit;
- performing a computation on the reference value and the second compensation data to obtain first compensation data corresponding to the pixel unit, wherein a storage bit length of the second compensation data is shorter than a storage bit length of the first compensation data;
- and
- using the first compensation data as decompressed compensation data of the pixel unit;
- wherein the dividing of the display panel into the at least one region comprises:
- dividing the display panel into a plurality of regions,
- obtaining reference values of two adjacent regions respectively, subsequent to dividing the display panel into the plurality of regions;
- and
- merging the two adjacent regions into one region, in a case where a difference value between the two reference values is within a preset threshold range.
A compensation data compression device of a display panel, the compensation data compression device comprising:
- a dividing circuit, configured to divide the display panel into at least one region;
- a determination circuit, configured to determine a reference value according to first compensation data of each pixel unit in each of the at least one region;
- and
- a computation circuit, configured to perform a computation on the first compensation data and the reference value to obtain second compensation data, wherein a storage bit length of the second compensation data is shorter than a storage bit length of the first compensation data;
- wherein the dividing of the display panel into the plurality of regions comprises:
- dividing the display panel into a plurality of regions,
- obtaining reference values of two adjacent regions respectively, subsequent to dividing the display panel into the plurality of regions;
