Embodiment 1

[0039] Exemplarily, see Figure 2-Figure 4 Embodiment 1 of the present invention provides an array substrate. The array substrate includes a display area 10 and a wiring area located on one side of the display area 10. The wiring area includes a laminated upper wiring layer 56 and a lower wiring layer. The wiring layer 56 and the underlying wiring layer are separated by an insulating layer group. The insulating layer group includes an insulating sublayer and an insulating organic compensation body 57 formed on the insulating sublayer. The insulating organic compensation body 57 is used to compensate at least part of the upper surface of the insulating sublayer sunken.

[0040] Since the upper wiring layer 56 is formed above the insulating layer group, when there are defects such as depressions or gaps on the upper surface of the insulating layer group, the display effect of the display screen will be affected. In this embodiment, the insulating layer group includes an insulat...

Embodiment 2

[0073] Embodiment 2 of the present invention provides a display screen, which includes a chip 40 and the above-mentioned array substrate. Further, the chip 40 is located on the same side of the display area 10 of the array substrate as the bending area 20 , pad area 30 and fan-out area 50 of the array substrate, and the chip 40 is electrically connected to the display area 10 . Such as figure 2 As shown, the chip 40 is located on the side where the pad region 30 is located, and the chip 40 is electrically connected to the first wiring sublayer 51 , the second wiring sublayer 53 and the upper wiring layer 56 .

Abstract

The present invention provides an array substrate and a display screen, wherein the array substrate includes a display area and a wiring area on one side of the periphery of the display area, the wiring area includes a stacked upper wiring layer and a lower wiring layer, and the upper wiring layer The lower wiring layer is spaced apart by an insulating layer group including an insulating sublayer and an insulating organic compensator formed on the insulating sublayer, the insulating organic compensator being used for compensating at least part of the concavity of the upper surface of the insulating sublayer. In the present invention, the insulating organic compensator is provided, and the insulating organic compensator is used to fill the depression in the insulating sub-layer, so that the metal used for forming the upper wiring layer can be prevented from entering the depression of the insulating sub-layer, and the occurrence of metal in the depression is difficult to remove. Therefore, the short-circuit phenomenon caused by the metal staying in the recess is avoided, the adverse effect on the array substrate is reduced, and the yield of the array substrate and the display effect of the display screen are improved.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate and a display screen. Background technique [0002] With the rapid development of display technology, displays with a high screen-to-body ratio are becoming more and more popular. One of the more commonly used displays at present is to set the fan out area (fan out), bending area (bending), pad area (Pad) and chip (IC) on the same side of the display screen, while the other three sides are not. Set fan-out area, bend area or pad area to achieve high screen-to-body ratio. [0003] In the above-mentioned display screen, there are multi-layer traces in the fan-out area, and these multi-layer traces are insulated by an insulating layer. When there are defects such as depressions or gaps in the insulating layer, these defects will affect the display effect of the display screen.
