Abstract

The present disclosure relates to a display substrate. The display substrate includes an active region and a non-active region, and a depth camera is disposed in the non-active region. The depth camera includes at least one receiving unit and a plurality of diffractive units. At least a part of the diffractive units includes an infrared light emitting device disposed on the substrate that emits infrared light. The part of the diffractive units includes a diffractive optical element disposed on the infrared light emitting device and used to transmit the infrared light emitted from the infrared light emitting device to an object. The receiving unit includes an infrared photosensitive device disposed on the substrate and used to receive the infrared light reflected by the object.
