Display panel and manufacturing method thereof

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel includes: a display area and a non-display area; the display area is arranged in the center of the whole display panel; the non-display area is arranged on the periphery of the display area and an identification code pattern is further arranged on one of the sides of the non-display area; and the identification code pattern is produced by using exposure with an exposure machine and then by using dotting with a coding machine, and the identification code pattern is a regular graph. The beneficial effect is as follows: firstly, the identification code pattern is arranged inside the non-display area of the display panel provided by the application, and the identification code pattern is a regular graph and produced by using the exposure with the exposure machine and then by using the dotting with the coding machine without the need for adding a new machine or changing a production process, thus the coding time is shortened and the production cycle is reduced; and secondly, since the identification code pattern is produced by using the exposure with the exposure machine and then by using the dotting with the coding machine, the exposure accuracy of the exposure machine can reach 3 [mu]m, which greatly reduces the size of the identification code pattern and is beneficial for realizing a narrow frame.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the production process of the display panel, in order to easily distinguish the information of the glass (that is, the liquid crystal display motherboard) and track the whereabouts of the glass, each glass will be marked with a Glass ID (LCD motherboard identification code). The glass is actually cut into multiple small sub-display panels. In order to distinguish each sub-display panel, a Panel ID (sub-display panel identification code) is generally produced on each sub-display panel. [0003] However, in the production process of the display panel, due to the number of identification codes and the long coding cycle of the entire coding machine, the production capacity of the production line will be affected, and due to the size of the LCD motherboard identification code and sub-display panel ident...

AI Technical Summary

Problems solved by technology

[0005] This application relates to a display panel and a manufacturing method thereof, which are used to solve the problem in the prior art that in the manufacturing process of the display panel, there are many identification codes of the liquid crystal display motherboard and sub-display panel, the production cycle is long, and the display panel occupies a large amount of time. The problem with the larger area of ​​the non-display area
