Embodiment 1

[0033] like figure 1 and figure 2 As shown, this embodiment provides an array substrate, including: a substrate 1 , a signal line 2 disposed on the substrate 1 , and an insulating layer 3 disposed on a layer where the signal line 2 is located close to the substrate 1 . In particular, in this embodiment, the insulating layer 3 has a groove; part of the edge of the signal line 2 falls into the groove.

[0034] In the array substrate provided in this embodiment, by setting grooves in the insulating layer 3, the grooves located above the insulating layer 3 ( figure 1 The edge of the signal line 2 on the side away from the substrate 1) falls into the groove, so that the distance between the signal line 2 in this part and other electronic components on the array substrate is increased in disguise, and the signal line 2 and other electronic components on the array substrate are avoided as far as possible. Defects occur between other electronic components due to too narrow spacing....

Embodiment 2

[0048] This embodiment provides a display panel, including any one of the array substrates provided in Embodiment 1.

[0049] Specifically, the display panel can be any product or component with a display function such as an organic light emitting diode (OLED) display panel, electronic paper, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, and navigator.

Embodiment 3

[0051] like Figure 1 to Figure 5 As shown, this embodiment provides a method for preparing an array substrate, which can be used to prepare any of the array substrates provided in Embodiment 1. The preparation method may include the following steps:

[0052] S11, forming an insulating layer 3 on the substrate 1 through a patterning process; the insulating layer 3 has grooves.

[0053] In this step, an insulating layer 3 may be formed on the substrate 1, and then grooves are formed on the insulating layer 3 by an etching process. Wherein, the position of the groove corresponds to the signal line 2 to be formed later.

[0054] S12 , forming the signal line 2 on the substrate 1 formed with the insulating layer 3 , and part of the edge of the signal line 2 falls into the groove.

[0055] In this step, a conductive layer (such as a metal layer) may be formed on the substrate 1 first, and then the signal line 2 is formed by an etching process. For the position of the signal lin...

Abstract

The invention provides an array substrate, a preparation method thereof and a display panel, belongs to the technical field of display, and can at least partially solve the problem that adjacent signal lines in an existing high-resolution display substrate are prone to short circuit. The array substrate comprises a substrate body and a signal line arranged on the substrate body. The array substrate is characterized in that the array substrate further comprises an insulating layer arranged on one side, close to the substrate, of the layer where the signal lines are located; the insulating layer is provided with a groove; and a part of the edge of the signal line falls into the groove.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an array substrate and a preparation method thereof. Background technique [0002] In the existing large-size high-resolution display panel, as the thickness and line density of the signal lines increase, the width of the signal lines becomes narrower, and the line spacing between the signal lines is also relatively close, so that during the preparation process of the signal lines, In the process of etching and patterning, higher requirements are placed on the exposure capability, copper etching process and environmental particles. It is required that the exposure has the ability to expose thin line width signal lines and narrow line spacing, and the environmental particles remain as little as possible. However, due to the fluctuation of process conditions and environmental particles, especially in the process of exposure and etching, metal residues of narrow metal l...
