Patent ID: 10197830

Abstract:
The present disclosure provides a display device and a method for controlling a grating. The display device includes at least a pixel array and a grating. The pixel array comprises a plurality of columns of pixels. Each pixel includes at least one sub-pixel. Upper edges of odd-numbered columns of sub-pixels are aligned and upper edges of even-numbered columns of sub-pixels are aligned, and each of the odd-numbered columns of sub-pixels and each of the even-numbered columns of sub-pixels are staggered longitudinally. The grating comprises a liquid crystal layer and a first substrate. The electrodes of the first substrate are arranged to correspond to a region where a portion of the odd-numbered columns of, or the even-numbered columns of, sub-pixels of the pixel array is located. A corresponding region of the grating is turned on or turned off so as to form a light shielding region and a light transmitting region.
