Problems solved by technology

[0004] The organic layer or planarization layer (PLN) in the existing display is a transparent material without shading effect. After the distance between the thin film transistor (TFT) and the opening or dividing line is reduced, the external light will pass through the opening or dividing line. The line enters through the organic layer or the planarization layer (PLN), which affects the characteristics of the thin film transistor (TFT), thereby affecting the display effect

Abstract

The invention discloses an array substrate, a stretchable display panel and a display device, and relates to the technical field of electronic display devices. The array substrate includes a base substrate, a planarization layer, a pixel defining layer, a first electrode layer, and a thin film encapsulation layer which are successively stacked; a thin film transistor is disposed between the planarization layer and the base substrate; a plurality of openings are disposed to pass through the thin film encapsulation layer, the first electrode layer, the pixel defining layer, the planarization layer, and the base substrate to define a plurality of islands spaced apart; the edge of the first electrode layer extends to a sidewall covering the planarization layer for shielding the thin film transistor against light; the edge of the first electrode layer is in contact with a conductor; and the conductor passes through a bridge region arranged between the openings and the islands and used for connecting adjacent islands in order to be used as a power wire for connecting the first electrode layers of the adjacent islands.

Description

technical field [0001] The present invention relates to the technical field of electronic display devices, in particular to an array substrate, a display panel and a display device. Background technique [0002] Stretchable displays need to dig holes or set dividing lines on the display substrate and the film layer above the substrate, so that the display substrates form a plurality of islands distributed in an array and separated from each other, and each of the plurality of islands Islands are connected by a plurality of bridges to make the display substrate stretchable; the openings or dividing lines are used to set the camera or stretch. [0003] There is an invalid area between the opening or dividing line and the thin film transistor (TFT) in the existing stretchable display. At present, electronic screen products tend to increase the display area. In order to increase the display area, the opening or dividing line must be reduced The inactive area between the thin fi...
