Abstract:
1. An apparatus for aligning a to-be-aligned display panel by self-alignment exposure, wherein a first group of pixels and a second group of pixels are distributed at intervals on the to-be-aligned display panel; the to-be-aligned display panel includes a first substrate and a second substrate, a first polarizer is provided on the first substrate, and a light alignment layer is provided on the first polarizer, the apparatus including: a base platform, for placing the to-be-aligned display panel, an area of the base platform corresponding to a display area of the to-be-aligned display panel is transparent; a display panel driving system connected to the to-be-aligned display panel; under the control of the display panel driving system, areas of the to-be-aligned display panel corresponding to the first group of pixels are in a light-transmissive state, and areas of the to-be-aligned display panel corresponding to the second group of pixels are in a light-shading state; a first exposure light source located to be closer to the second substrate, light irradiating towards the first substrate from the second substrate is linearly polarized light; and a second exposure light source located to be closer to the first substrate, light emitted from the second exposure light source is linearly polarized light, the polarization direction of which is orthogonal to the transmission axis direction of the first polarizer.
