Title:
DISPLAY DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/188427
Kind Code:
A1
Abstract:
A display device, comprising a display panel (1) having a plurality of photosensitive sensing units (10). The display device further comprises a light hole forming layer (20), a liquid crystal lens layer (30), and a light guide layer (40) which are located on the display side of the display panel (1) and arranged in sequence in the direction distant from the display panel (1), as well as a light source (41) provided on the side of the light guide layer. The light hole forming layer (20) can be switched between a light transmitting state and an aperture state, and in the aperture state, the light hole forming layer (20) is used for forming light holes directly facing each photosensitive sensing units (10). The liquid crystal lens layer (30) can be switched between a non-lens state and a lens state, and in the lens state, the liquid crystal lens layer (30) is used for forming convex lenses directly facing each photosensitive sensing units (10). Also provided is a control method for the display device.
