Problems solved by technology

In the process of coating PI liquid, the PI liquid should not overflow the driving circuit (otherwise it will cause the insulation of the driving circuit and hinder the conduction of the driving circuit), which will increase the difficulty of coating the PI liquid
The current design method of the area where the driving circuit is located is: forming the driving circuit in the entire large groove, so that the probability of the PI liquid spreading and overflowing the large groove increases, thereby causing the PI liquid to diffuse and overflowing the driving circuit. increased risk

Abstract

The present application provides an array substrate. The array substrate includes a display area and a non-display area surrounding the display area; the non-display area further includes a binding area; At least two diversion grooves and at least two groups of driving circuit holes are formed on the array substrate, one of the diversion grooves surrounds a group of the driving circuit holes; each of the diversion grooves includes a a first inner wall, the first inner wall is far away from the corresponding driving circuit hole, the first inner wall includes at least one arc-shaped segment facing the display area and at least one connecting segment smoothly connecting the arc-shaped segment . The present application also provides a display panel. The array substrate and the display panel provided by the present application can reduce the risk of the alignment film forming liquid flowing through the diversion groove and reduce the coating difficulty of the alignment film forming liquid.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an array substrate and a display panel. Background technique [0002] In Thin Film Transistor-Liquid Crystal Display (TFT-LCD), a Chip On Film (COF) substrate is usually used to connect a Printed Circuit Board (PCB) and an array substrate together. Thereby, the PCB board can output the driving control signal to the array panel to complete the corresponding driving control. One end of the COF substrate is electrically connected to the driving circuit of the array substrate, and the other end is electrically connected to the PCB board. In the current liquid crystal display panel, an alignment film is provided on the side of the array substrate. The alignment film can provide a pre-tilt angle to the liquid crystal molecules, so that the liquid crystal molecules are arranged in an orderly manner. For the formation of the alignment film, an alignment film forming li...
