Abstract

The invention relates to a contraposition system used in a stereo display device and a contraposition method thereof. In the contraposition system, an image capture apparatus is used to respectively acquire a contraposition deviation image comprising locations of a first image capture point and a second image capture point after a micro-retarder is attached to a partial area of a liquid crystal display panel. And contraposition deviation image information is transmitted to a contraposition control device. The contraposition control device calculates a first contraposition deviation distance and a second contraposition deviation distance from the contraposition deviation image and a deviation angle of the micro-retarder and the liquid crystal display panel. Therefore, at least one of a attaching apparatus and a bearing apparatus is controlled to adjust and compensate the deviation angle. The areas which are not attached with the micro-retarder in the liquid crystal display panel are attached with the micro-retarder. Therefore, by using the system and the method of the invention, a yield rate of the stereo display device can be increased and costs can be reduced.

Description

technical field [0001] The invention relates to stereoscopic display technology, and in particular to an alignment system and an alignment method for a stereoscopic display device. Background technique [0002] In recent years, with the development of high-definition television technology, people's pursuit of more realistic display image technology has become higher and higher. Three-dimensional display technology has become a research hotspot and is gradually applied to film and television, advertising, exhibitions, games and other fields. [0003] figure 1 Shown is a schematic diagram of an existing stereoscopic display device using polarized glasses. Such as figure 1 As shown, it is composed of a liquid crystal display panel 10 , a micro-retarder film (Micro-retarder) 11 , and polarized glasses 12 . The liquid crystal display panel 10 includes a first glass substrate 101, a second glass substrate 102, a liquid crystal layer 103 located between the first and second glas...
