Abstract

The invention discloses an array substrate and a manufacturing method thereof. The array substrate comprises a display area and a winding area, wherein the array substrate comprises a substrate, an active layer, a first insulating layer, a first metal layer, a second insulating layer, a second metal layer, a third insulating layer, a third metal layer, a patterned flat layer, a pixel defining layer and a supporting layer. The first metal layer comprises at least one first wiring pattern arranged on the first insulating layer in the winding area, the second metal layer comprises at least one second wiring pattern arranged on the second insulating layer in the winding area, the third metal layer comprises at least one third wiring pattern arranged on the third insulating layer in the windingarea, and the pixel defining layer and the supporting layer in the winding area jointly have at least one undercut structure. According to the array substrate and the manufacturing method thereof, the width of a boundary formed by the winding area can be reduced.

Description

technical field [0001] The present invention relates to a substrate and a manufacturing method thereof, in particular to an array substrate and a manufacturing method thereof. Background technique [0002] Full screen is one of the goals of OLED display technology development. The current under-display camera technology is mainly through forming a hole in the display panel for accommodating a camera. However, the above-mentioned hole is formed by removing the base substrate of a camera area, so it is easy to affect the packaging effect, and has the problem of poor reliability. [0003] In order to solve the above problems, the prior art is to provide a plurality of groove structures under the transistor structure of the array substrate at positions adjacent to the hole (for example, at the boundary between a display area and the camera area), Each of the plurality of groove structures has an undercut structure. During subsequent encapsulation steps, an organic layer (or i...
