Title:
GRATING ADJUSTMENT DEVICE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/142476
Kind Code:
A1
Abstract:
A grating adjustment device (100) and a display device, relating to the technical field of display. The grating adjustment device (100) comprises a first substrate (1), a conductive layer (1), a dielectric layer (19), and a second substrate (2) that are stacked. The conductive layer (18) comprises a wiring layer (26), a first insulating layer (27), and a first electrode layer (3) that are stacked. The wiring layer (26) comprises a plurality of driving lines (24). The first electrode layer (3) comprises a plurality of sub-electrodes (25) arranged in a first direction. The driving lines (24) are used for transmitting a driving signal to the sub-electrodes (25). The sub-electrodes (25) are used for driving, under the action of the driving signal, the dielectric layer (19) at a corresponding position to transmit light or not to transmit light. The grating adjustment device (100) comprises a grating area (G1). The grating area (G1) comprises a plurality of common signal units (23). Each common signal unit (23) comprises at least one grating unit (20). The grating unit (20) comprises a plurality of sub-electrodes (25). The plurality of sub-electrodes (25) located in a same grating unit (20) is respectively connected to different driving lines (24). The plurality of sub-electrodes (25) located in the same grating unit (20) is sorted in a first direction. The sub-electrodes (25) located in a same common signal unit (23) and having the same serial number are connected to a same driving line (24).
