specific Embodiment approach 1

[0028] Specific implementation mode 1. Combination Figure 2 to Figure 6 Describe this embodiment, the 3D-LED module described in this embodiment includes n 3D polarizing films, n LED display modules and light-transmitting layers; the n 3D polarizing films spliced ​​together are located in the light-transmitting layer and n Between the LED display modules, there is a one-to-one correspondence between n 3D polarizing films and n LED display modules;

[0029] The method for eliminating the white edge is: implanting m light-absorbing grating structures at the edge of the 3D polarizing film, so that any two 3D polarizing films are spliced ​​to form m prism reflection structures along the splicing line, and each prism reflection structure consists of two A combination of light-absorbing grating structures is formed, and m prism reflection structures on the splicing line are used to reflect the light output from the LED display module through the splicing point out of the field of v...

Abstract

A method for eliminating white edges displayed on a 3D-LED module belongs to the field of stereoscopic displays. The invention aims to solve the problem of poor white edge elimination effect on large-size display screens. The method of the present invention is: implanting m light-absorbing grating structures at the edge of the 3D polarizing film, so that any two 3D polarizing film splicing places form m prism reflection structures along the splicing line, and each prism reflection structure consists of two light-absorbing grating structures Formed together, the m prism reflection structures on the splicing line are used to reflect the light output from the LED display module through the splicing point out of the field of vision on the left and right sides, thereby eliminating white edges.

Description

technical field [0001] The invention belongs to the field of three-dimensional display, and in particular relates to a technology for eliminating white edges of a combination unit of a 3D polarizing film and an LED display module. Background technique [0002] Polarized stereoscopic display is a 3D display method that uses the principle of "vibration direction" of light to realize the decomposition of the original image and stereoscopic imaging. It mainly uses left-handed and right-handed polarizing films on adjacent rows of the display device In this way, two pictures with different polarization directions are sent to the viewer, and when the pictures pass through the polarized glasses, since each lens of the polarized glasses can only accept pictures with one polarization direction, the left and right eyes of the person can only receive two pictures. Group pictures, and then form stereoscopic vision through brain fusion. The core component involved in this polarized stereo...
