System for aligning and attaching a 3D image display and method for positioning a phase retarder substrate

摘要

A method for positioning a phase retarder substrate includes the following steps. A phase retarder substrate is provided, wherein the phase retarder substrate includes a first align mark which includes a patterned phase retarder film. An image capturing unit is disposed at one side of the phase retarder substrate. A light source is disposed at the other side of the phase retarder substrate. An upper polarizing sheet is disposed between the image capturing unit and the patterned phase retarder film, and a lower polarizing sheet is disposed between the light source and the patterned phase retarder film. An image of the light which passes through the lower polarizing sheet, the patterned phase retarder film and the upper polarizing sheet is captured so as to position the phase retarder substrate.

1. A method for positioning a phase retarder substrate comprising the following steps of:
providing a phase retarder substrate comprising a first align mark which comprises a patterned phase retarder film; disposing an image capturing unit at one side of the phase retarder substrate; disposing a light source at the other side of the phase retarder substrate; disposing an upper polarizing sheet between the image capturing unit and the patterned phase retarder film, and disposing a lower polarizing sheet between the light source and the patterned phase retarder film; and emitting a light to the patterned phase retarder film by the light source, and then capturing an image of the light which passes through the lower polarizing sheet, the patterned phase retarder film and the upper polarizing sheet by the image capturing unit so as to position the phase retarder substrate.
