Abstract

In order to solve the problem that the resolution of a traditional stereoscopic display is not high, the invention provides a high-resolution grating stereoscopic display device. The device is composed of a point light source array, a transparent liquid crystal display panel, a scattering layer and a light splitting element which are sequentially arranged from front to back. The transparent liquid crystal display panel does not change the light propagation direction, and in any pixel column, pixels of different parallax images are arranged in the vertical direction; any pixel is provided with a plurality of opening units; and pixel opening units of different parallax images are periodically arranged in the horizontal direction. The light source array can project the opening units belonging to different parallax image pixels on the transparent liquid crystal display panel to different spatial positions on the scattering layer, so that new pixels are formed. The optical element can project new pixels to different viewpoint positions respectively, thereby providing stereoscopic vision. According to the invention, physical interpolation of the pixels is carried out in the process of projecting the opening units and forming the new pixels, so that the image resolution is improved.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display, and more specifically, the invention relates to a high-resolution grating stereoscopic display device. Background technique [0002] A traditional grating stereoscopic display device is usually formed by coupling a 2D display panel and a light splitting element. The light splitting element can project pixels belonging to different parallax images to different viewpoint positions, and human eyes can see the corresponding parallax images at the viewpoint positions, thereby generating stereoscopic vision. Generally, when there are M pixels on the 2D display panel and the number of viewpoints is N, the image viewed at the viewpoint has M / N pixels, so its resolution is low. Therefore, the present invention proposes a high-resolution grating stereoscopic display device. The invention realizes the pixel interpolation of the parallax image through the optical projection method, thereby pro...
