Problems solved by technology

In the manufacturing process of the above-mentioned array substrate, due to the complexity of the process, instability or dust pollution, etc., the lead wires in the peripheral lead area are often disconnected.
When the display panel is finally formed, these disconnected leads will cause no signal input to the grid lines or data lines connected to the disconnected leads, resulting in poor display of the screen; when the situation is more serious, the entire liquid crystal display panel will be made Scrap treatment, which greatly reduces the product yield and economic benefits
