Abstract

The invention belongs to the technical field of three-dimensional display and provides an optical-grating three-dimensional display device and an optical grating sheet thereof. The display device comprises a display panel and an optical grating sheet arranged on the display panel, wherein the horizontal distance between adjacent sub-pixels in the same line on the display panel becomes large and small alternatively; the positions of the sub-pixels in the same line on the display panel go up and down alternatively; oblique optical grating electrodes are distributed at equal intervals on the optical grating sheet; and the optical grating period of the optical grating sheet is the width of four sub-pixels on the display panel. In the optical-grating three-dimensional display device provided by the invention, the optical grating sheet with the oblique optical grating electrodes is adopted, and the optical grating period of the optical grating sheet is the width of the four sub-pixels, so that the cross effect caused by unequal intervals among the sub-pixels is avoided when the display panel is an active matrix display panel based on a dual-grid framework, and a good three-dimensional display effect and strong applicability are achieved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and in particular relates to a grating type stereoscopic display device and a grating sheet thereof. Background technique [0002] A stereoscopic display device refers to a display device that can reproduce three-dimensional scene information and display images with a three-dimensional effect, so that the audience can obtain a more intuitive and comprehensive visual experience. The grating-type stereoscopic display device alternately displays left / right parallax images by columns of pixels on the display panel, and utilizes the shielding effect of the grating sheet to enable the audience to obtain a visual stereoscopic display image without the audience wearing stereoscopic glasses. [0003] For display panels with different pixel structures, the blocking methods of the grating sheet are different. When the pixel structure of the display panel is horizontal color bars, such as figu...
