Display panel and display apparatus

A display panel, including:

• a display region,
• wherein the display region comprises a first display region and at least one second display region that are arranged along a first direction:
• the first display region comprises a first display sub-region and at least one second display sub-region that are arranged along a second direction;
• and the second display sub-region is provided with a photosensitive element;
• wherein the display region comprises sub-pixels distributed in an array:
• the sub-pixels comprise first sub-pixels located in the first display sub-region, second sub-pixels located in the second display sub-region, and third sub-pixels located in the at least one second display region;
• wherein the display region further comprises driving units:
• the driving units comprise first driving units, second driving units, and third driving units;
• and the third driving units are located in the at least one second display region and are electrically connected to the third sub-pixels in one-to-one correspondence, so as to drive the third sub-pixels to emit light;
• wherein the first driving units and the second driving units are located in the first display sub-region;
• the first driving units are electrically connected to the first sub-pixels in one-to-one correspondence, so as to drive the first sub-pixels to emit light;
• and the second driving units are electrically connected to the second sub-pixels in one-to-one correspondence, so as to drive the second sub-pixels to emit light;
• wherein in the first display region, an orthographic projection of any one of the driving units on a light exit surface of the display panel has an area S1, and in the second display region, an orthographic projection of any one of the driving units on the light exit surface of the display panel has an area S2, where ½<S1:S2≤1;
• and
• wherein the first direction intersects with the second direction.
