Problems solved by technology

[0002] In the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display substrate, the IC (Integrated Circuit, integrated circuit) area has a touch screen wiring horizontal DAM structure, which is prone to short circuit. There are many short-circuit problems in the touch screen traces where the IC crosses the DAM, which affects the overall yield of the screen.

Abstract

The present application discloses a display substrate, a preparation method, and a display device. The display substrate includes a display area and a non-display area. The non-display area includes a functional layer, a retaining wall arranged on the functional layer, and layer and the encapsulation layer of the retaining wall, the retaining wall includes a bottom surface close to the functional layer, a top surface opposite to the bottom surface, and opposite two sides, at least one side has a recessed structure, and the recessed structure makes the On a plane parallel to the display substrate, the length of the side on the plane is greater than the length of the side on the plane parallel to the display substrate when the side is a plane. In the embodiment of the present application, by adding a recessed structure to the retaining wall and changing the edge shape of the retaining wall, the short-circuit distance between two touch screen panel traces is increased and the risk of short-circuit is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a preparation method thereof, and a display device. Background technique [0002] In the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Diode, AMOLED) display substrate, the IC (Integrated Circuit, integrated circuit) area has a touch screen wiring horizontal DAM structure, which is prone to short circuit. There are many short-circuit problems in the touch screen traces where the IC crosses the DAM, which affects the overall yield of the screen. Contents of the invention [0003] At least one embodiment of the present invention provides a serial peripheral interface circuit and a display panel to improve display quality. [0004] In order to achieve the purpose of the present invention, at least one embodiment of the present invention provides a display substrate, including a display area and a non-display area, and the n...
