Claim 11:
12. A method for photo alignment, applied to a device for photo alignment, the device for photo alignment comprising:
a bearing platform;
a linearly polarized light source, located at one side of the bearing platform; and
a control assembly, located between the linearly polarized light source and the bearing platform;
wherein one side of the bearing platform close to the control assembly is configured for placing a large plate glass to be aligned, and the large plate glass to be aligned comprising a plurality of alignment areas;
wherein the linearly polarized light source is configured for providing a first polarized light to the control assembly; the control assembly is configured for adjusting a polarization direction of the first polarized light, and configured for providing a second polarized light to the plurality of alignment areas comprised in the large plate glass to be aligned;
wherein polarization directions of the second polarized light respectively corresponding to at least two alignment areas are different;
wherein the control assembly comprises a plurality of control modules, and the control modules and the alignment areas on the large plate glass to be aligned are in one-to-one correspondence; and
the control modules are configured for adjusting the polarization direction of the first polarized light corresponding to the alignment to form the second polarized light
and the method comprises:
placing a large plate glass to be aligned comprising a plurality of alignment areas on one side of a bearing platform close to a control assembly;
providing a first polarized light to the control assembly through a linearly polarized light source; and
providing a second polarized light to the plurality of alignment areas comprised in the large plate glass to be aligned, after adjusting a polarization direction of the first polarized light through the control assembly;
wherein polarization directions of the second polarized light respectively corresponding to at least two alignment areas are different.
