Contraposition method of grating panel and display panel, and grating panel

Abstract

The invention discloses a contraposition method of a grating panel and a display panel, and the grating panel. The contraposition method is used for achieving contraposition of the grating panel and the display panel; each contraposition mark of the grating panel is made of a light-proof material; the contraposition method comprises the following steps that the grating panel is bonded with the display panel in a contraposition manner; on each first contraposition region (located on the grating panel) and each second contraposition region (located on the display panel) which are bonded in a contraposition manner, a superposed image after the contraposition is conducted on the first contraposition regions and the second contraposition regions is obtained at the same time; whether the centers of the contraposition marks are located in the centers of corresponding hollow regions (located on the display panel) is judged according to the image; if so, the contraposition of the grating panel and the display panel is accomplished; if not, the centers of the contraposition marks are adjusted to the centers of the corresponding hollow regions; and the contraposition of the grating panel and the display panel is accomplished. The invention further discloses the grating panel which can apply the contraposition method of the grating panel and the display panel smoothly.

Description

technical field [0001] The invention relates to an alignment method, in particular to an alignment method for realizing precise alignment between a grating panel and a display panel, and the grating panel. Background technique [0002] Such as figure 1 As shown, the 2D display module 1000, that is, the display panel, may be a flat panel display device such as TFT_LCD, OLED or PDP. The alignment mark (mark) on the substrate used in the 2D display module 1000, such as glass, is generally located on the four corners of the 2D display module 1000, and thus four second alignment regions 1004 are formed on the four corners. The alignment area 1004 is a non-light-transmitting area, and a hollow area 1001 is provided in the center to allow the center of the corresponding second alignment area 1004 to transmit light. The hollow area 1001 forms an alignment mark on the 2D display module 1001 . In fact, according to the size of the space, the hollow area 1001 as the alignment mark of...

Problems solved by technology

[0004] Since the grating 2000' for stereoscopic display generally uses indium tin oxide (ITO) as the electrode material on the upper and lower substrates, and the alignment mark 2001' used for the upper and lower substrates is also made of ITO, the formed alignment mark 2001' cannot be used for For lamination and alignment with the 2D display module 1000, the angle and displacement of the lamination are often adjusted by using the glass reference edge or observing the stereoscopic display effect, resulting in large errors and low production capacity
