Display panel, array substrate and method for preparing same

A method for preparing an array substrate, comprising:

• forming a driving circuit layer on a side of a base substrate, wherein the driving circuit layer is provided with a first pillow body on a peripheral region of the array substrate;
• the first pillow body comprises a first pillow metal block located on at least one of a source drain metal layer and a gate layer and a first pillow insulating layer covering the first pillow metal block;
• sequentially forming an organic thin film layer and a conductive layer on a side of the driving circuit layer away from the base substrate;
• wherein the organic thin film layer is defined with a barrier groove on the peripheral region, a part of the first pillow body is covered by the organic thin film layer and the other part of the first pillow body is exposed by the barrier groove;
• the conductive layer is provided with a signal wire passing across an edge of the barrier groove, and an edge of the signal wire at least partially overlaps with the first pillow body.

A display panel, comprising an array substrate;

• wherein the array substrate comprises a base substrate, a driving circuit layer, an organic thin film layer and a conductive layer sequentially stacked;
• wherein the driving circuit layer is provided with a first pillow body on a peripheral region of the array substrate;
• the first pillow body comprises a first pillow metal block located on at least one of a source drain metal layer and a gate layer and a first pillow insulating layer covering the first pillow metal block;
• the organic thin film layer is defined with a barrier groove on the peripheral region, a part of the first pillow body is covered by the organic thin film layer and the other part of the first pillow body is exposed by the barrier groove;
• a conductive layer is provided with a signal wire passing across an edge of the barrier groove, and an edge of the signal wire at least partially overlaps with the first pillow body.
