Embodiment Construction

[0048]The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] As described in the background art, the array substrate includes a display area and a frame area. The display area is provided with related wirings to control the pixels to light up, so as to realize the display of the image; the non-display area is provided with a driver chip and a driver chip connected to the driver chip. Fan-out wiring, the driver chip transmits the driving signal to the related wiring in the display area thro...

Abstract

The invention provides an array substrate and a display panel, comprising: a base substrate; a planarization layer on the base substrate, the planarization layer including a hollow area extending along a first direction; The interlayer insulating layer between the layers, a plurality of fan-out wirings are arranged in the interlayer insulating layer, and at least one signal line arranged between the plurality of fan-out wirings and the planarization layer; the signal line in the first direction At least one side has an edge overlapping area with at least one edge line of the hollow area in the second direction; on the orthographic projection of the base substrate, the fan-out routing extends through the hollow area, and the fan-out routing intersects at least one edge The overlapping area does not overlap. On the orthographic projection of the base substrate, the fan-out traces are arranged without overlapping with at least one edge overlapping area, so that the fan-out traces can avoid the edge overlap area that is easily corroded by water vapor, thereby improving the efficiency of the fan-out traces. In the case of water vapor corrosion, the reliability of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to an array substrate and a display panel. Background technique [0002] With the development of display technology, liquid crystal display panels, organic light-emitting display panels, etc. are widely used in mobile phones, TVs, personal digital assistants, digital cameras, notebook computers, Various consumer electronic products such as desktop computers have become the mainstream of display devices. One of the important components of the display panel is the array substrate. The array substrate includes a display area and a frame area. The display area is provided with related wirings to control the pixels to light up, so as to realize the display of the image; the non-display area is provided with The driving chip and the fan-out wiring connected to the driving chip, the driving chip transmits the driving signal to the relevant wiring in the display area thro...
