Problems solved by technology

However, in the process of forming the alignment film, due to the low viscosity of the PI liquid, it is not easy to control, so the PI liquid is easy to diffuse to the binding area, thereby affecting the binding effect of the array substrate, and may also cause the PI liquid in the display area to be too large. Thin, resulting in uneven display of the display panel

Embodiment Construction

[0026] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The present application discloses an array substrate, a display panel and a display device, which relate to the field of display technology. The array substrate includes: a display area and a non-display area arranged around the display area; The conductive pad; the fan-out routing area is arranged between the display area and the binding area, the fan-out routing area includes a number of first fan-out routing, second fan-out routing and third fan-out routing, the first fan-out routing and The second fan-out routing extends along the first direction and is arranged along the second direction. The first fan-out routing, the second fan-out routing and the third fan-out routing are respectively located in different film layers; the signal leads in the display area are routed through the fan-out The line is electrically connected to the conductive pad; the alignment film barrier structure is arranged in the fan-out wiring area, and the alignment film barrier structure is set on the same layer as the third fan-out wiring. In the second direction, two adjacent alignment film barrier structures face the first The vertical projection in one direction is continuous. In this way, it can effectively prevent the alignment film from diffusing to the binding region.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an array substrate, a display panel and a display device. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (ThinFilm Transisitor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. The liquid crystal display panel is an important part of a liquid crystal display, mainly including an array substrate and a color filter substrate arranged opposite to each other, and a liquid crystal layer is filled between them. As panel displays are more and more widely used, widescreen technology has become an important technical item. At the same time, the technology of narrow lower borders of display panels has also attracted more and more attention. Advanced electronic products, especially portable electronic products, tend to be sm...
