Display panel and display apparatus

A display apparatus, comprising a display panel;

• wherein the display panel has a first display region, a second display region, a third display region, and at least one fourth display region, wherein the third display region is located at least one side of the first display region in a first direction, the second display region at least partially surrounds the first display region and the third display region, the first display region is reused as a photosensitive element integration region, and the at least one fourth display region is located between the third display region and the second display region in a second direction intersecting with the first direction and is located between the first display region and the second display region in the second direction;
• and
• wherein the display panel comprises:
• first pixel circuits and first light-emitting elements, wherein the first pixel circuits are electrically connected to the first light-emitting elements, the first light-emitting elements are located in the first display region, and the first pixel circuits are located in the third display region;
• second pixel circuits and second light-emitting elements, wherein the second pixel circuits are electrically connected to the second light-emitting elements, and the second pixel circuits and the second light-emitting elements are located in the second display region;
• third pixel circuits and third light-emitting elements, wherein the third pixel circuits are electrically connected to the third light-emitting elements, and the third pixel circuits and the third light-emitting elements are located in the third display region;
• fourth pixel circuits and fourth light-emitting elements, wherein the fourth pixel circuits are electrically connected to the fourth light-emitting elements;
• the fourth pixel circuits and the fourth light-emitting elements are located in the at least one fourth display region;
• the fourth pixel circuits are arranged in at least one row in the at least one fourth display region, wherein each of the at least one row of the fourth pixel circuits comprises at least one first arrangement unit arranged along the first direction, wherein each of the at least one first arrangement unit comprises N fourth pixel circuits of the fourth pixel circuits and a first interval space, N is a positive integer, wherein the N fourth pixel circuits are sequentially arranged adjacent to each other along the first direction, and the first interval space is located at a side of the N fourth pixel circuits along the first direction;
• and
