Abstract

Embodiments of the present invention disclose a parallax barrier, a designing method thereof and a parallax barrier type 3D display device. The parallax barrier comprises: a plurality of grating sheets, utilized to shield light, disposed in an arrangement direction and spaced apart from each other, wherein the plurality of grating sheets are divided into 2K identical grating sections each of which comprises two or more grating segments, each grating segment comprises one or more grating sheets with an identical grating pitch C, and the grating sheets included in different grating segments have different grating pitches, and the 2K grating sections are arranged symmetrically about a center line of the parallax barrier in the arrangement direction, and K is a natural number.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a slit grating and a slit grating type stereoscopic display device. 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 slit grating type stereoscopic display device alternately displays the left parallax image and the right parallax image by the pixels of the display panel in columns, and arranges a slit grating in parallel between the display panel and the backlight in front of the display panel or in the liquid crystal display panel. The shielding effect of the grating sheet of the slit grating allows the left eye and the right eye to see the left parallax image and the right parallax image displayed by the pixels of the display panel r...
