Problems solved by technology
[0002] In related technologies, the mobile phone will be equipped with a fingerprint identification module and a display module. The fingerprint identification module can identify the user's identity through the electrical signal generated by the fingerprint identification unit. However, the electric field of the display drive unit easily interferes with the electrical signal generated by the fingerprint identification unit, resulting in lower quality fingerprint images acquired by the fingerprint identification module and lower identification accuracy

The invention discloses a display device. The display device comprises a first substrate, a driving layer, a photosensitive layer and a liquid crystal layer which are stacked. the driving layer comprises a plurality of driving units arranged in an array mode, the driving units are used for driving liquid crystal molecules of the liquid crystal layer to deflect, the photosensitive layer comprises a plurality of photosensitive units arranged in an array mode, the photosensitive units are used for generating electric signals according to optical signals, and effective working time of the photosensitive units and the driving units located in the same row or column is staggered. The invention further discloses an electronic device and an image acquisition method. The photosensitive unit can receive an optical signal entering the display device from the outside. An image of an object touching the display device can be obtained according to the optical signal. Meanwhile, due to the fact that the effective working time of the photosensitive units and the effective working time of the driving units located in the same row or the same column are staggered, electric fields generated by the driving units do not affect the photosensitive units easily, the quality of images obtained according to the electric signals of the multiple photosensitive units is high, and the accuracy for fingerprint recognition is high.
Description
technical field [0001] The present application relates to the field of display technology, and more specifically, to a display device, electronic equipment, and an image acquisition method. Background technique [0002] In related technologies, the mobile phone will be equipped with a fingerprint identification module and a display module. The fingerprint identification module can identify the user's identity through the electrical signal generated by the fingerprint identification unit. However, the electric field of the display drive unit easily interferes with the electrical signal generated by the fingerprint identification unit, resulting in lower quality fingerprint images acquired by the fingerprint identification module and lower identification accuracy. Contents of the invention [0003] Embodiments of the present application provide a display device, an electronic device, and an image acquisition method. [0004] The display device according to the embodiment of...
