Manufacturing method and manufacturing apparatus for display panel

1. A manufacturing method for a display panel, comprising steps of:

applying an alignment material on a main substrate;

placing a lighting baffle between the main substrate and a light source to control a light transmittance;

exposing the main substrate to develop and form an alignment layer;

cutting the main substrate to obtain a plurality of display panels;

wherein a light blocking pattern configured to control the light transmittance is disposed in the lighting baffle, and

the lighting baffle is detachable or the light blocking pattern is changeable;

wherein the lighting baffle comprises at least two regions, and the light blocking patterns having different light transmittances are disposed respectively in each one of the regions, and

a size and a shape of each one of the regions are adjustable through changing the lighting baffle or through changing the light blocking pattern.

2. The manufacturing method for the display panel of claim 1 , wherein the main substrate is divided into different sections corresponding to different display panels, and, corresponding to different sections, the light blocking patterns having different light transmittances are disposed on the lighting baffle, and

the light transmittances for the light blocking patterns are configured to respectively correspond to the aperture ratios of the display panels, and a magnitude of light transmittance is in inversely proportional to the aperture ratio of the display panel.

3. The manufacturing method for the display panel of claim 2 , wherein the main substrate is a main glass substrate, and the lighting baffle is a UV lighting baffle.

4. The manufacturing method for the display panel of claim 1 , wherein the main substrate is a main glass substrate, and the lighting baffle is a UV lighting baffle.

5. A manufacturing apparatus fora display panel, comprising:

an installation unit configured to hold a main substrate;

a coating unit configured to apply an alignment material;

a light source configured to expose the main substrate to develop and form an alignment layer;

a lighting baffle disposed between the installation unit and the light source, wherein a light transmittance of the lighting baffle is controllable; and

a cutting unit configured to cut the main substrate to obtain a plurality of display panels after the development of the alignment layer is complete;

wherein a light blocking pattern configured to control the light transmittance is disposed in the lighting baffle, and

the lighting baffle is detachable or the light blocking pattern is changeable;

wherein the lighting baffle comprises at least two regions, and the light blocking patterns having different light transmittances are disposed respectively in each one of the regions, and

a size and a shape of each one of the regions are adjustable through changing the lighting baffle or through changing the light blocking pattern.
