Abstract

The invention provides a three-dimensional display device with a variable slit pitch. The display device is composed of a liquid crystal display panel, a light source, a cylindrical lens grating and a multilayer polymer dispersed liquid crystal. The light source, the cylindrical lens grating and the multilayer polymer dispersed liquid crystal are used for forming a rear slit grating. The rear slit grating can project parallax images on the liquid crystal display panel to different space directions, so that viewpoints are formed. When human eyes are located at different viewpoints, corresponding parallax images can be seen, and therefore stereoscopic vision is generated. The multilayer polymer dispersed liquid crystal is composed of multiple polymer dispersed liquid crystal layers, and one polymer dispersed liquid crystal layer can be selected to be in a strong scattering state so as to control the pitch of the rear slit grating. Different grating pitches can form viewpoints at different optimal viewing distances.

Description

technical field [0001] The present invention relates to display technology, more specifically, the present invention relates to stereoscopic display technology. Background technique [0002] Stereoscopic display devices can be used for displaying stereoscopic images. Common stereoscopic display devices are composed of components such as slits or cylindrical lens gratings, 2D display panels, etc., which provide parallax composite images through 2D display panels, and use the splitting effect of slits or cylindrical lens gratings to realize stereoscopic image display. However, it is difficult to adjust the grating pitch in conventional stereoscopic display devices, so the present invention proposes a stereoscopic display device with variable slit pitch, which provides parallax composite images by using a liquid crystal display panel, and utilizes a light source, a cylindrical lens grating and Multilayer polymer-dispersed liquid crystal forms the rear slit grating. It can con...
