Claim 2:
3. The display panel according to claim 1, wherein the collimation film comprises at least two collimation hole layers arranged in a laminated mode and a light transmitting layer arranged between every two adjacent collimation hole layers; wherein
each collimation hole layer comprises a plurality of light-shielding parts and a collimation hole array arranged among the light-shielding parts;
the collimation hole array is roughly identical in distribution, and centers of orthographic projections of correspondingly arranged collimation holes on the first base substrate roughly coincide with each other; and
the collimation holes are the second light transmitting holes, and in a region where the photosensitive sensors are located, an orthographic projection of each collimation hole on the first base substrate correspondingly overlaps with an orthographic projection of the first light transmitting hole on the first base substrate.
