Abstract

The embodiment of the invention discloses a display device, which comprises a display panel, a photoelectric sensor and a light reflecting unit, and is characterized in that the light reflecting unitis arranged on one side, far away from a light emitting surface of the display panel, of the photoelectric sensor; the photosensitive surface of the photoelectric sensor comprises a first photosensitive area and a second photosensitive area; a first photosensitive area of the photoelectric sensor faces the light emitting surface of the display panel; a second photosensitive area of the photoelectric sensor faces the reflective surface of the reflective unit; and the reflective surface of the reflective unit is used for reflecting light to the second photosensitive area of the photoelectric sensor. Compared with the prior art, according to the display device provided by the embodiment of the invention, the reflecting unit can be utilized; at least part of light which is not received by thefirst light sensing area is reflected to the second light sensing area, so that the part of light can be received by the second light sensing area, the total amount of light received by the photoelectric sensor can be increased, the light utilization rate can be improved, the light sensing accuracy can be improved, and the light sensing precision can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the continuous development of display technology, in order to improve user experience, other functional components such as touch sensing module, camera module and fingerprint recognition module can be integrated in the display device, so that the display device can display images while also It has touch sensing function, camera function and fingerprint recognition function, etc. [0003] At present, camera modules and fingerprint identification modules usually include photoelectric sensors to convert optical signals into electrical signals, and then perform corresponding functions through data processing. However, due to the light leakage at the edge of the photoelectric sensor, its light absorption is small, and the light utilization rate is low, so that the photosensitive accuracy is low, the photosensitive accuracy...
