Title:
Dual-Pitch Parallax Barrier
Document Type and Number:
WIPO Patent Application WO/2018/131326
Kind Code:
A1
Abstract:
A reconfigurable parallax barrier panel, for use in a display system with a 3D mode, includes a first substrate, a second substrate, and an electro-optic material positioned between the first and second substrates. The first and second substrates each respectively has a plurality of first and second electrodes, the electrodes being independently addressable from one another and comprising a plurality of electrode portions extending along a first direction and laterally spaced from one another along a second direction different from the first direction. The electrode portions of the first electrodes are arranged in a cyclic arrangement having a first pitch, and the electrode portions of the second electrodes are arranged in a cyclic arrangement having a second pitch that is different to the first pitch. The first and second electrodes are driven to generate different reconfigurable parallax barrier arrays corresponding to different viewing positions (left-right, forwards-backwards) in a 3D mode of operation.
