Problems solved by technology

[0004] In the manufacturing process of the existing display panel, the transparent electrode layer will be scratched and damaged, and the scratches are concentrated at the four corners of the substrate, which is easy to form cracks and cracks, resulting in the inability to continue to use the display panel, further increasing the production cost of the display panel

Abstract

The invention discloses a method for manufacturing a display panel, comprising the steps of: providing a substrate; transporting the substrate to a coating chamber; clamping the edge position of the substrate with a clamp; performing coating operation; releasing the clamp from the clamp, and The substrate is transported out of the coating chamber. By clamping the end position of the substrate with the clamp, it can effectively disperse the force points and disperse the force of the four corners to the end position of the substrate, thereby effectively avoiding scratches and damage points on the substrate, and further The chipping rate of the substrate is reduced, the yield rate in the production process of the display panel is ensured, the scrapping cost of the display panel is effectively reduced, and the market competitiveness of the display panel is further improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a manufacturing method and manufacturing equipment of a display panel. Background technique [0002] The display has many advantages such as thin body, power saving, no radiation, etc., and has been widely used. Most of the displays currently on the market are backlight displays, which include a display panel and a backlight module. The working principle of the display panel is to place liquid crystal molecules between two parallel substrates, and apply a driving voltage on the two substrates to control the rotation direction of the liquid crystal molecules, so as to refract light from the backlight module to generate images. [0003] Among them, Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has gradually occupied a dominant position in the display field due to its low power consumption, excellent picture quality, and high production yield. Similarly, a thin fi...
