Autostereoscopic display equipment sub-pixel arranging method based on vertical column mirror grating

Abstract

The invention relates to an autostereoscopic display equipment sub-pixel arranging method based on a vertical column mirror grating, belonging to the technical field of the autostereoscopic display equipment sub-pixel arranging. On the display equipment, red, green and blue sub-pixels are separately arranged, the sub-pixels with the same color are in line in the horizontal direction, one kind of circulating arrangement in the arrangement modes of the red, green and blue sub-pixels is arranged in the vertical direction, one group of red, green and blue sub-pixels in the vertical direction form a pixel unit, the column mirror grating is arranged in front of the display equipment in parallel, and the lens strips on the column mirror grating are vertically arranged. The invention has the advantages that the structure is simple, and the design is reasonable; the column mirror diaphragm is vertically arranged, and all the colors of a view point can be seen; through the amplifying action of a column mirror, a pixel unit in the vertical direction can be amplified to a square undistorted image pixel. In addition, a left eye and a right eye can only see the image of a single view point respectively through a grating, and the images of the two view points are synthesized into a stereo image without the image mixing interference of other view points, so that the definition of watching can be improved.

Description

technical field [0001] The invention belongs to the technical field of sub-pixel arrangement of autostereoscopic display devices, and in particular relates to a method for arranging sub-pixels of autostereoscopic display devices based on vertical lenticular gratings. Background technique [0002] With the continuous development of display technology, people have developed a variety of free stereoscopic display technologies that can directly watch stereoscopic images without the aid of stereoscopic glasses and other auxiliary tools, mainly including lenticular grating stereoscopic display, slit grating Stereoscopic display, holographic stereoscopic display, etc. Among the many autostereoscopic display technologies, the autostereoscopic display technology based on lenticular lens grating has become a relatively common autostereoscopic display technology because of its outstanding stereoscopic effect. [0003] The grating type free stereo display device is made by adding a gra...

Problems solved by technology

Usually, when the 2D image pixels of N viewpoints are rearranged for stereoscopic display in this way of sub-pixel arrangement, if the grating is installed vertically, what you see is a monochromatic sub-pixel in the vertical direction, and the accurate color of the stereoscopic image cannot be correctly restored. , so the lens stripes on the lenticular grating must be tilted at a certain angle

The lenticular lens grating with inclined angle is difficult to manufacture and seriously affects the clarity of the stereoscopic image. If it is used to display the stereoscopic effect on a large screen, the lenticular lens grating must be spliced. If there is an error in the inclination angle of the lens stripes on each lenticular lens It will lead to a larger overall error after splicing, which will greatly reduce the stereoscopic playback effect
