Stereoscopic display method and stereoscopic display device

Abstract

The invention discloses a stereoscopic display device and a control method thereof. The stereoscopic display device comprises a display panel and a grating. The grating and the display panel are arranged oppositely so as to realize a stereoscopic display; the grating includes a plurality of micro optical structures; the display panel includes a plurality of display units in an array arrangement; each display unit includes two parallel first side parts which extend in a first direction and two parallel second side parts which extend in a second direction different to the first direction; an included angle exists between a tilt direction of the plurality of micro optical structures and an extension direction of the second side parts of the plurality of display units; the plurality of display units comprises three sub display units which respectively display a single color and are orderly arranged, wherein the three sub display units includes a first sub display unit, a second sub display unit, and a third sub display unit; and the first sub display unit, the second sub display unit, and the third sub display unit respectively include a long edge parallel to the first direction and a short edge parallel to the second direction, wherein the length of the long edge is larger than that of the short edge.

Description

technical field [0001] The present invention relates to the field of stereoscopic display, in particular to a stereoscopic display method and a stereoscopic display device, and more particularly to a stereoscopic display device and a control method thereof. Background technique [0002] With the rapid development of stereoscopic display technology, people's demand for stereoscopic display devices is also increasing. Among them, the naked-eye stereoscopic display device is widely favored by the market because it does not need to wear glasses. Existing naked-eye stereoscopic displays are mainly developed based on binocular parallax, and mainly include grating type stereoscopic displays. The grating-type stereoscopic display has the advantages of simple structure and easy implementation, but at the same time, it also has disadvantages such as poor definition and large crosstalk between left and right eye images. However, the above-mentioned shortcomings have restricted the fu...

Problems solved by technology

On this type of display panel, the gratings are usually placed in regular rectangular vertical strips, which will encounter serious crosstalk and color shift.

In the document of patent application publication number CN102004324A, a method of using a tilted grating is disclosed, the grating includes a plurality of micro-optical structures, and there is an angle between the tilting direction of the micro-optical structures and the diagonal direction of the display unit of the display panel , although this method can eliminate color shift and reduce crosstalk, but because the display unit is placed in a rectangular vertical strip, this will cause each sub-display unit in the display unit to be cut by the micro-optical structure of the grating, and the degree of cutting is different

There will still be a large crosstalk, which will seriously affect the display effect
