Patent attributes
A photosensitive unit, a photosensitive module and a display device are provided. The photosensitive unit includes: a light-emitting structure, a photoelectric converter, an optical waveguide device and a collimator. The converter and collimator are disposed on the same side of the optical waveguide device side by side, the light-emitting structure is disposed on one side of the converter away from the optical waveguide device, and one side on the converter close to the light-emitting structure is light-shielding; the light-emitting structure is capable of emitting light rays to a target side thereof away from the converter; the collimator is capable of screening collimating light rays in the light rays incident from the target side, and controlling the collimating light rays to be incident to the optical waveguide device; the optical waveguide device is capable of controlling the collimating light rays incident from the collimator to be incident to the converter.
