Display panel and brightness compensation method, chip and display device thereof

A display panel, comprising a plurality of preset regions, wherein

• a preset region of the plurality of preset regions comprises at least one first pixel;
• when the display panel is in a first state, a data voltage received by the first pixel is related to a Gamma curve corresponding to at least one preset region adjacent to a preset region where the first pixel is located;
• and
• the preset region of the plurality of preset regions comprises a first region and a second region, wherein
• the first region is located on a side of the second region close to an adjacent preset region, and the first pixel is located in the first region;
• and
• the second region comprises at least one second pixel, and a data voltage received by the second pixel is related to:
• a grayscale value that is required to be displayed by the second pixel;
• a Gamma curve corresponding to a preset region where the second pixel is located;
• at least a portion of the second region in the plurality of preset regions comprises one second pixel;
• and
• the plurality of preset regions comprise an edge preset region and a non-edge preset region, wherein
• the edge preset region is adjacent to an edge of the display panel;
• and
• the non-edge preset region is located on a side of the edge preset region away from the edge of the display panel, wherein
• the second region in the non-edge preset region comprises one second pixel;
• the second region in the edge preset region is located on a side of the first region adjacent to the edge of the display panel;
• and
• the second region in the edge preset region comprises multiple second pixels.

A brightness compensation method for a display panel, wherein

• the display panel comprises a plurality of preset regions;
• and
• the method comprises:
• determining an associated preset region corresponding to a target image pixel based on the target image pixel in a to-be-displayed image, wherein the associated preset region is adjacent to a preset region where a first pixel is located and the first pixel is required for displaying the target image pixel in the display panel;
• obtaining an associated preset data voltage corresponding to the associated preset region based on a Gamma curve corresponding to the associated preset region;
• and
• obtaining a target data voltage at least based on the associated preset data voltage, wherein the target data voltage is a data voltage transmitted to the first pixel corresponding to the target image pixel when the to-be-displayed image is displayed, and wherein at least one other pixel in the display panel, located in a same preset region as the first pixel, receives a data voltage that is unrelated to Gamma curves corresponding to preset regions adjacent to the preset region where the first pixel and the at least one other pixel are located.
