1. A display panel, comprising:
a display substrate
a light sensor, formed in the display substrate and configured to sense ambient light; and
a light absorption layer, disposed on the display substrate, located at an incident light side, and overlapped with the light sensor; wherein a material of the light absorption layer comprises an infrared light absorbent and an ultraviolet light absorbent;
wherein a transmittance of visible light of the light absorption layer is a first transmittance, and a transmittance of ultraviolet and infrared light of the light absorption layer is a second transmittance, and wherein the first transmittance is greater than 5%, and the second transmittance is less than 2%;
wherein the transmittance of the light absorption layer decreases in a wavelength range from 800 nm to 855 nm of the infrared wavelength region;
wherein a half-peak width of the transmittance spectrum curve of the light absorption layer, referring to a peak width at half a height of the peak, ranges from 300 nm to 400 nm, and a peak value of the half-peak corresponding to the transmittance greater than 2% ranges from 380 nm to 780 nm.
