Embodiment Construction

[0019] The structure of the grating alignment system of the present invention will be described below with reference to the accompanying drawings.

[0020] see figure 1 , which is a structural schematic diagram of a preferred embodiment of the grating alignment system of the present invention. The grating alignment system 1 includes a display device 10 , a cylindrical grating 11 and an alignment device (not shown).

[0021] The display device 10 is a common liquid crystal display (liquid crystal display, LCD), and may also be a plasma display (plasma display panel, PDP), a field emission display (field emission display, FED), an organic electroluminescence display (organic light emitting diode, OLED) or LCD display module. The display module includes a liquid crystal display, a backlight module and an iron frame, and the iron frame fixes the liquid crystal display and the backlight module to each other. When batch production is carried out on the production line, a power su...

Abstract

The invention provides an alignment device for realizing exact alignment of a display device and a grating. The alignment device comprises a mechanical arm, an image detection element and a control module. The display device displays a reference image, and the image detection element detects image information formed by the reference image by transmitting the cylindrical grating and transmits the image information to the control module. The control module judges alignment condition of the cylindrical grating and the display device according to the image information and controls the mechanical arm to carry out alignment adjustment on the cylindrical grating according to the alignment condition. The invention realizes the automatic exact alignment of the grating and the display device and improves the assembly efficiency. Meanwhile, the invention provides a grating alignment system adopting the alignment device and an alignment method thereof.

Description

technical field [0001] The invention relates to an alignment device, an alignment system and an alignment method thereof, in particular to an alignment device which realizes accurate alignment between a display device and a grating and has high alignment efficiency, and an alignment system using the alignment device and counterpoint method. Background technique [0002] There is a gap between the left and right eyes of a person, resulting in a slight difference in the viewing angle of the two eyes. Such a difference will cause a slight displacement of the scene observed by the left and right eyes respectively, thereby forming a three-dimensional image in the human brain. This difference Known as parallax. [0003] With the development of stereoscopic display technology, the application prospect of autostereoscopic display has been widely concerned. At present, the mainstream autostereoscopic display is mainly based on the principle of binocular parallax and light separatio...
