Title:
LIQUID CRYSTAL LENS, DISPLAY DEVICE AND DRIVING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/133818
Kind Code:
A1
Abstract:
A liquid crystal lens, a display device and a driving method therefor, the liquid crystal lens comprising: a first substrate (1) and a second substrate (2); a liquid crystal layer (3), the liquid crystal layer (3) comprising a plurality of liquid crystal lens units (31); a first electrode (4), the first electrode (4) comprising a plurality of independent sub-electrodes (41), wherein the number of sub-electrodes (41) corresponding to each liquid crystal lens unit (31) is the same, and there are sub-electrodes (41) at adjacent positions of adjacent liquid crystal lens units (31); a second electrode (5), the second electrode (5) being a planar electrode, wherein the first electrode (4) and the second electrode (5) are configured to form an electric field so as to drive liquid crystal molecules of the liquid crystal layer (3) to rotate, and adjust the curvature of the liquid crystal lens units (31); a first planar layer (6), which is located on the side of the first electrode (4) facing the liquid crystal layer (3), the first planar layer (6) being configured to smooth an intensity variation curve of the electric field of the liquid crystal lens units (31); and a light-shielding layer (7), which is located between the first substrate (1) and the second substrate (2), wherein an orthographic projection of the light-shielding layer (7) on the first substrate (1) covers an orthographic projection of the sub-electrodes (41) at the adjacent positions of the adjacent liquid crystal lens units (31) on the first substrate (1).
