Abstract
The invention provides a photo-alignment apparatus and a photo-alignment method. In photo-alignment apparatus, a movable polarizing element is disposed between loading platform and light source; when the LC panel to be aligned uses display mode of horizontal alignment, moving the polarizing element to below light source to convert non-polarized light emitted from light source into linearly polarized light to irradiate on the LC panel to be aligned to perform alignment; when the LC panel to be aligned uses display mode of vertical alignment, moving the polarizing element to a region outside of below light source, so that the non-polarized light emitted from light source irradiating on the LC panel to be aligned to perform alignment. As such, the present invention can be applied to horizontal alignment and vertical alignment respectively, improve the usability of the photo-alignment apparatus, reduce the manufacturing cost, save space and reduce management load.
