DISPLAY DEVICE

WIPO Patent Application WO/2018/145461

A1

Provided is a display device, comprising a display panel (100) having a plurality of pixel units (12); a protection cover plate (200) disposed on a light emitting surface of the display panel (100); and a plurality of light-sensing devices (300) disposed on a side of the pixel unit (12) facing away from the light emitting surface for line discernment. The display device is added with a light collimating member (400) disposed between the protection cover plate (200) and the plurality of photosensitive devices (300). The light collimating member (400) has a light-transmitting area (A) above the photosensitive device (300). Outside the light-transmitting area (A) is a light-blocking area (B). The light-blocking area (B) can filter stray light of a portion of adjacent valley ridges and the display light emitted from the pixel unit (12) from indenting on the photosensitive device (300). The light-transmissive area (A) can ensure that the reflected light of the ridge is effectively incident on the corresponding photosensitive device (300).
