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 invention provides an array substrate. The array substrate comprises a display area and a non-display area surrounding the display area; the non-display area further comprises a binding area; at least two diversion trenches arranged at intervals and at least two groups of driving circuit holes are formed in the array substrate in the binding area, wherein one diversion trench surrounds one group of driving circuit holes; and each diversion trench comprises a first inner wall, the first inner wall is far away from the corresponding driving circuit hole, and the first inner wall comprises atleast one arc-shaped section facing the display area and at least one connecting section smoothly connected with the arc-shaped section. The invention further provides a display panel. According to the array substrate and the display panel, the risk that alignment film forming liquid overflows the diversion trenches can be reduced, and the coating difficulty of the alignment film forming liquid is reduced.

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 a 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, Therefore, the PCB board can output the drive control signal to the array panel to complete the corresponding drive 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 current liquid crystal display panels, 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 ordered. The formation of the alignment film needs to coat the alignment film forming liquid (generally ...
