Abstract

In order to solve the problem of low resolution of traditional stereoscopic displays, the present 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 placed in sequence from front to back. The transparent liquid crystal display panel does not change the direction of light propagation, and in any pixel column, the pixels of different parallax images are arranged in the vertical direction; any pixel has multiple opening units; the pixel opening units of different parallax images are periodically in the horizontal direction arrangement. The light source array can respectively 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, thereby forming new pixels. Optical elements can project newly created pixels to different viewpoint positions respectively, thus providing stereopsis. The present invention performs physical interpolation of pixels during the process of projecting the aperture unit and forming new pixels, thereby improving image resolution.

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...
