3D grating alignment attaching method, device and system

Abstract

The invention provides a 3D grating alignment attaching method. The method includes the following steps of: S1. separately presetting different images in a left eye image layout and a right eye imagelayout of a display panel; S2. analyzing left eye detection images or right eye detection images collected by detection lenses through a 3D grating member; S3. determining whether the left eye detection images or the right eye detection images are consistent with the preset different images, if so, entering step S5, and if not, entering step S4; S4. adjusting a slit position of the 3D grating member to enable a left eye image to be viewed by the left eye of a viewer through an adjusted slit and to enable a right eye image to be viewed by the right eye of the viewer through the adjusted slit, and entering step S5; and S5. achieving attaching between the 3D grating member and the display panel. The invention also discloses a 3D grating alignment attaching device and system. According to the3D grating alignment attaching method, device and system, automatic attaching is achieved, the attaching standard is uniform and the attaching efficiency is high.

Description

technical field [0001] The invention relates to the field of 3D bonding, in particular to a method, device and system for aligning and bonding 3D gratings. 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), and 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 bonded to th...

Problems solved by technology

[0004] At present, if the grating is not aligned, crosstalk will occur or the stereo will be poor

[0005] There are some traditional grating laminating equipment such as cold laminator, hot laminator and laminating machine, which can complete some simple laminating actions, but these machines and laminating processes are not perfect enough, and there are many problems. The main problems are as follows: 1) During the fitting process, the fitting position is mainly judged by human eyes, and the positioning is done manually, so that the fitting accuracy cannot be guaranteed; 2) During the fitting process, the operator’s The requirements and dependencies are relatively high, the labor cost is high, and it requires the cooperation of multiple people to complete
