Title:
GRATING, GRATING DRIVING METHOD AND 3D DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/104575
Kind Code:
A1
Abstract:
A grating (10), comprising: a first substrate and a second substrate which are arranged opposite to each other, a liquid crystal layer being arranged between the first substrate and the second substrate, a first electrode layer and a second electrode layer which are stacked being provided on the first substrate, the first electrode layer and the second electrode layer each comprising a plurality of strip-shaped electrodes with the same width, and the strip-shaped electrodes in the first electrode layer and the strip-shaped electrodes in the second electrode layer being arranged in a staggered manner; a plurality of driving modules configured to drive the plurality of strip-shaped electrodes to form light-shielding portions and light-transmitting portions, the adjacent light-shielding portion and light-transmitting portion forming a grating unit, at least one grating unit forming a grating portion, and the plurality of driving modules being arranged in one-to-one correspondence with the plurality of grating portions; and a control module configured to form, according to the distance between the human eyes and the grating, a plurality of driving signals corresponding to the plurality of driving modules on a one-to-one basis, so as to change the width of a grating unit corresponding to a crosstalk position.
