Abstract

The embodiment of the invention provides a stereoscopic display device and a switching unit, and relates to the technical field of stereoscopic display. The switching unit comprises a plurality of ladder light-permeable bars; ladder electrodes and polymer dispersed liquid crystals are arranged between the ladder light-permeable bars; through a slit grating formed by the ladder structures, the level cycle of the grating is guaranteed to be unchanged, and the interference of moire fringes can be alleviated compared with the prior art. Meanwhile, compared with a slantly arranged slit grating, the slit grating formed by the ladder structures can be used for strictly separating sub-pixels of each view point, so that the problem of mutual interference between the view points is reduced. Through mutual parallel connection among between the ladder electrodes, a part of the ladder electrodes are powered on or powered off, so that the polymer dispersed liquid crystals in the switching unit are partially arranged in order and are partially arranged in disorder, the purposes that a part of the polymer dispersed liquid crystals are light-permeable and a part of the polymer dispersed liquid crystals are not light-permeable are reached, and a display interface that a partial 2D effect and a partial 3D effect coexist is further realized.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular, to a stereoscopic display device and a switching unit. Background technique [0002] Vision is an important channel for human beings to obtain external information. How to reproduce the depth level of human perception of objects through binocular parallax on the display has always been a dream pursued by people. With the development of technology, 3D display technology can be divided into vision-assisted stereoscopic display technology and auto-stereoscopic display technology. The so-called visual aid stereoscopic display technologies such as time-sharing, color-separation, and light-splitting technologies need to wear auxiliary devices or equipment to view the stereoscopic effect. The so-called autostereoscopic display technology can watch the stereoscopic effect without any auxiliary device or equipment. It can be mainly divided into slit grating and cylindr...
