Abstract

A display panel and a display apparatus includes sub-pixels, and First and second regions arranged along a first direction. First sub-pixel groups in the first region and second sub-pixel groups in the second region are arranged along the first direction, and each include at least two sub-pixels arranged along the second direction. A number of the sub-pixels in the second sub-pixel group close to the first region is greater than a number of the sub-pixels in the second sub-pixel groups away from the first region. The first sub-region of the second region is closer to the first region than the second sub-region. From the first region to the second region, a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the first sub-region is greater than a variation rate of the numbers of the sub-pixels in the second sub-pixel groups in the second sub-region.

Dependent claims

A display panel, comprising a plurality of sub-pixels, wherein the display panel has a first region and a second region that are arranged along a first direction,

wherein first sub-pixel groups are located in the first region of the display panel and are arranged along the first direction, and at least one of the first sub-pixel groups comprises at least two sub-pixels of the plurality of sub-pixels that are arranged along a second direction intersecting with the first direction;
wherein second sub-pixel groups are located in the second region of the display panel and are arranged along the first direction, and at least one of the second sub-pixel groups comprises at least two sub-pixels of the plurality of sub-pixels that are arranged along the second direction;
wherein a number of the at least two sub-pixels in each of the first sub-pixel groups is greater than a number of the at least two sub-pixels in each of the second sub-pixel groups;
and, among the second sub-pixel groups, a number of the at least two sub-pixels in one of the second sub-pixel groups that is close to the first region is greater than a number of the at least two sub-pixels in one of the second sub-pixel groups that is away from the first region;
wherein the second region comprises a first sub-region and a second sub-region, the first sub-region is closer to the first region than the second sub-region;
