Odd-viewpoint, free and stereo sub-pixel arranging method based on vertical lenticular lens grating

Abstract

The invention relates to an odd-viewpoint, free and stereo sub-pixels arranging method based on a vertical lenticular lens grating, belonging to the technical field of sub-pixel arrangement on a free and stereo display device. In the invention, red, green and blue sub-pixels on the display device are separately arranged; homochromatic sub-pixels are arranged in a row in the horizontal direction; circular arrangement in arrangement modes of the red, green and blue sub-pixels is utilized in the vertical direction; one group of the red, green and blue sub-pixels in the vertical direction constitutes a pixel unit; the lenticular lens grating is parallelly arranged in the front of the display device; and lens stripes on the lenticular lens grating are vertically arranged. In the invention, the structure is simple and the design is reasonable; the lenticular lens grating is vertically arranged; and all colors of viewpoints can be seen; when an observer changes the view angle, the switchover of the viewpoints is smooth without feeling of picture jumping, and black lines among the sub-pixels can be avoided being simultaneously seen by left and right eyes; and narrow sides of the red, green and blue sub-pixels are horizontally arranged on the display device, therefore, the grating distance of the lenticular lens grating is greatly decreased and the resolution of stereo play images is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of sub-pixel arrangement of autostereoscopic display equipment, and in particular relates to a method for arranging autostereoscopic sub-pixels of odd viewpoints based on a vertical lenticular grating. 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 g...

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. , and when viewed at a certain angle, the left and right eyes see black lines between two sub-pixels, so the lens stripes on the lenticular grating must be set 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
