Title:
LIQUID CRYSTAL SLIT GRATING, 3D DISPLAY DEVICE, AND DRIVING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/000448
Kind Code:
A1
Abstract:
A liquid crystal slit grating (200), comprising stacked in order a first polarizing sheet (21), a first substrate (22), an upper electrode structure (23), a first alignment layer (24), a liquid crystal layer (25), a second alignment layer (26), a lower electrode structure (27), a second substrate (28), and a second polarizing sheet (29); the lower electrode structure (27) comprises at least two layers of electrode layers (271, 272), and each electrode layer (271, 272) comprises multiple strip electrodes (271a, 272a) extending in the same direction; the strip electrodes (271a, 272a) in the at least two layers of electrode layers (271, 272) are arranged in a parallel, separate, and mutually electrically insulated configuration, and the strip electrodes (271a, 272a) in different electrode layers (271, 272) are arranged corresponding to the gaps between one another and in an alternating configuration, such that the projection of the multiple strip electrodes (271a, 272a) on the second substrate (28) is a seamless projection and completely covers the liquid crystal layer (25) corresponding to the projection area. The liquid crystal slit grating (200) can adjust parameters such as the grating spacing, the widths of the light-transmitting slits, and the positions of the light-transmitting slits. Also provided are a 3D display device using the liquid crystal slit grating (200) and the driving method of the 3D display device.
