1. A display panel comprising:
a display region and a photoelectric sensing region, wherein the display region is located outside the photoelectric sensing region, the display region comprises a plurality of pixels arranged in an array, each pixel of the plurality of the pixels comprises a plurality of color sub-pixels; and the photoelectric sensing region comprises a light transmitting region and a frame area that surrounds the light transmitting region, wherein the frame region comprises:
a first region surrounding the light transmitting region;
a second region located on a side of the first region away from the light transmitting region and surrounding the first region; and
a third region located on a side of a second region away from the light transmitting region and located between the second region and the display region to separate the second region from the display region;
a plurality of spacers arranged in an array, wherein the plurality of the spacers is located inside the display region while outside of the light transmitting region;
a plurality of first support pillars located inside the first region, arranged around the light transmitting region, and spaced away from each other;
a plurality of second support pillars located inside the second region, arranged around the second region, and spaced away from each other; and
a plurality of third support pillars located in the third region and arranged in an array,
wherein the third region is a non-display region, and an arrangement density and an arrangement form of the plurality of third support pillars arranged in the array in the third region are same as the arrangement density and the arrangement form of the plurality of spacers arranged in the array inside the display region.
