Glass-free 3d display module detection method, device and system

Abstract

The invention provides a glass-free 3d display module detection method. The method comprises the steps of first, separately presetting different images for left eye images and right eye images in a display panel; second, parsing a left eye detection image or a right eye detection image collected by a detection lens through a grating membrane; third, determining whether the left eye detection imageor the right eye detection image is consistent with the preset different images, if yes, performing a fourth step, if not, performing a fifth step; fourth, feeding back information that the detectedglass-free 3D display module is qualified; and fifth, feeding back information that the detected glass-free 3D display module is not qualified. The invention further discloses a glass-free 3d displaymodule detection device and system. Through adoption of the glass-free 3d display module detection method, device and system, automatic detection is realized, the detection standards are unified, andthe detection efficiency is high.

Description

technical field [0001] The invention relates to the field of 3D detection, in particular to a method, device and system for naked-eye 3D display module detection. Background technique [0002] With the rapid development of 3D (three dimensional) technology, naked-eye stereoscopic display technology is a very attractive cutting-edge technology direction today. Through naked-eye stereoscopic display equipment, viewers can directly watch stereoscopic movies without wearing 3D glasses. Stereoscopic images will become the most promising direction for flat panel display. [0003] From a technical point of view, naked-eye stereoscopic display devices include Barrier, Lenticular Lens technology, Directional Backlight and so on. Among them, the lenticular grating includes a display panel and a grating layer (grating film). The display panel has a left-eye pattern and a right-eye pattern. The prior art adopts a bonding process for the lenticular grating, and the grating layer is bond...

Problems solved by technology

[0004] At present, if the alignment of the grating is not aligned, crosstalk will occur or the stereo will be poor. The detection of the alignment of the alignment of the grating is done manually. There are many problems in manual detection: the alignment accuracy is low, and it is completely judged by human eyes. Fitting the position, the viewing angle changes, and the field of view will also change. Watching 3D, manual viewing, the depth of field is different, and the production standards are inconsistent. If the human eye sees it, the human eye has defects in the depth of field. The eyes have color weakness, color blindness, stereo blindness, and stereo weakness, and there are differences in the depth of field perception between people, and there are great inconsistencies in artificial

In short, the whole process is completely dependent on manual work, which is highly subjective, highly dependent on manual skill proficiency, and requires large manpower input and increased costs.
