Abstract

The invention provides a mask plate, a display panel and a preparation method thereof, the display panel comprises a display area and a peripheral area surrounding the display area, and the peripheralarea comprises a wiring area and a binding area. The wiring area is provided with a first grounding wire. According to the invention, the first grounding wire is wired through double-layer or multi-layer metal, and an ESD protection effect can be achieved in use of a finished product. Specifically, an original grounding wire of a single metal film layer is replaced with a mode of jumper wire in adouble-layer or multi-layer metal film layer to serve as a first grounding wire, and the antenna effect generated in the single-film-layer metal wire manufacturing process is weakened.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a large-size spliced ​​mask plate, a display panel and a preparation method thereof. Background technique [0002] The process flow of a large-size capacitive touch panel (Touch Panel, TP) is similar to that of a liquid crystal display (LCD). Since the size of the mask (Mask) is much smaller than the size of the TP that needs to be produced, it is necessary to use the same mask ( Mask) performs multiple exposures (shots) to splicing large-sized TPs, and the splicing screen uses a smaller-sized Mask to perform multiple exposures on a pattern (Pattern) in a certain area, and performs repeated exposures to splicing into the required TP. . [0003] Such as figure 1 As shown, in the prior art, in order to prevent electrostatic discharge (ESD), TP wraps a circle of ground wire 11 (GND) around the entire periphery of TP to shield ESD in the environment of TP finished products. Durin...
