1. A display panel having a plurality of pixels, each of which includes a subpixel region and an inter-subpixel region, the display panel comprising:
- a light filtering layer forming a light filtering region within the inter-subpixel region, the light filtering layer comprising a light filtering material at least partially transmissive for a light of a selected wavelength;
a photosensor in the light filtering region for detecting the light of the selected wavelength, the photosensor being sensitive to the light of the selected wavelength; and
a thin film transistor coupled to the photosensor for receiving a current from the photosensor;
wherein the photosensor comprises;
a transparent electrode layer proximal to a light emitting surface of the display panel;
a photoelectric conversion layer on a side of the transparent electrode layer distal to the light emitting surface of the display panel, wherein a resistance of the photoelectric conversion layer undergoes a change when the photoelectric conversion layer is irradiated by the light of the selected wavelength; and
a non-transparent electrode layer on a side of the photoelectric conversion layer distal to the transparent electrode layer.
