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 region 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 display panel further comprises:
a first substrate;
a second substrate opposite to the first substrate;
a black matrix located on a side of the second substrate adjacent to the first substrate, covering the frame region, and defining the plurality of the color sub-pixels in the display region;
a protection layer located in the second substrate and located on a side of the black matrix adjacent to the first substrate, covering the frame region and the display region, wherein the plurality of the spacers, the plurality of the first support pillars, the plurality of the second support pillars, and the plurality of the third support pillars are located between the first substrate and the protection layer to maintain a distance between the first substrate and the second substrate; and
a spacer layer located in a region which is on a side of the first region away from the light transmitting region, and is located between the black matrix and the protection layer, wherein the plurality of the second support pillars and the third support pillars are in the region surrounding the first region, and orthographic projections of the plurality of the second support pillars or the plurality of the third support pillars on the first substrate are respectively located within an orthographic projection of the spacer layer on the first substrate, wherein
the spacer layer comprises a second spacer layer located in the third region and located between the black matrix and the protection layer, and the orthographic projections of the plurality of the third support pillars are located within an orthographic projection of the second spacer layer on the first substrate.
