Compensation device and method for display apparatus, display apparatus, and computer storage medium

A display apparatus, comprising a display panel and a control assembly, wherein

• the display panel comprises sub-pixels for emitting beams of a first color;
• the control assembly is configured to acquire compensation data of a region to be compensated, wherein the compensation data is determined by:
• acquiring a first image in a case that the display apparatus displays a picture of the first color;
• determining a reference region in the first image based on a position of the region to be compensated in the first image in a first direction;
• and determining the compensation data based on average brightness of the reference region and average brightness of the region to be compensated;
• the reference region having a same position as the region to be compensated in the first direction and the reference region being greater than the region to be compensated;
• the control assembly is configured to perform, based on the compensation data, compensation on the region to be compensated of the picture displayed in the display panel, wherein the compensation data of the region to be compensated is configured to enable the display apparatus to adjust a region corresponding to the region to be compensated, such that brightness of the region to be compensated is consistent with average brightness of the reference region, and the region to be compensated is any region in the first image, and the position of the reference region varies with the position of the region to be compensate;
• and
• the control assembly is further configured to:
• determine, based on the position of the region to be compensated in the first direction, a strip-shaped region in which the region to be compensated is disposed, wherein the first image comprises a plurality of strip-shaped regions distributed in the first direction, and each of the plurality of strip-shaped regions is provided with a preset reference region;
• and determine the preset reference region in the strip-shaped region in which the region to be compensated is disposed as the reference region.

A compensation method for a display apparatus, comprising:

• acquiring a first image in a case that the display apparatus displays a picture of a first color, wherein the display apparatus comprises sub-pixels for emitting beams of the first color;
• determining a reference region in the first image based on a position of a region to be compensated in the first image in a first direction, wherein the reference region has a same position as the region to be compensated in the first direction, the reference region being greater than the region to be compensated;
• determining compensation data of the region to be compensated based on average brightness of the reference region and average brightness of the region to be compensated, wherein the compensation data of the region to be compensated is configured to enable the display apparatus to adjust a region corresponding to the region to be compensated, such that brightness of the region to be compensated is consistent with average brightness of the reference region, and the region to be compensated is any region in the first image, and the position of the reference region varies with the position of the region to be compensated;
• determining, based on the position of the region to be compensated in the first direction, a strip-shaped region in which the region to be compensated is disposed, wherein the first image comprises a plurality of strip-shaped regions distributed in the first direction, and each of the plurality of strip-shaped regions is provided with a preset reference region;
• and
• determining the preset reference region in the strip-shaped region in which the region to be compensated is disposed as the reference region.
