Array substrate, display pane and manufacturing method thereof, and display device

Abstract

The invention discloses an array substrate, a display panel and a manufacturing method thereof and a display device. The array substrate comprises a substrate and a pixel defining layer. The surface array of the substrate has a plurality of pixel grids, the pixel defining layer is disposed on the substrate, the pixel defining layer defines a plurality of pixel grids arranged in an array, the pixeldefining layer further comprises a plurality of thickness thinning regions, and the thickness thinning regions are suitable for guiding flow of the package layer. According to the array substrate provided by the embodiment of the invention, the pixel defining layer is laid on the substrate, is configured to define a plurality of pixel grids and comprises the plurality of thickness thinning regions, when the substrate is filled with the package layer, the thickness thinning regions can guide the flow direction of the package layer so as to allow the filling of the package layer to be uniform and avoid the condition of the excessive filling or non-full filling of the package layer to cause the conditions of failure or poor performances of the performances of the OLED.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular, to an array substrate, a display panel, a manufacturing method thereof, and a display device. Background technique [0002] The OLED (Organic Light-Emitting Diode, organic electroluminescent diode) display device includes an anode, an organic layer (including a hole transport layer and an electron transport layer, and an organic light-emitting layer between the hole transport layer and the electron transport layer) and cathode. Compared with LCD display devices, OLED display devices are thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, wide operating temperature range, and simple production process , high luminous efficiency and flexible display. Due to the incomparable advantages of other displays and bright application prospects, OLED has a...

Problems solved by technology

[0004] In the related art, in the top-emitting OLED device, during the encapsulation process, the fluidity of the filling encapsulation layer is weak, and it is often difficult to fill or overfill

As a result, part of the device is not filled by the encapsulation layer, resulting in bubbles; or excessive encapsulation layer in some areas, and the auxiliary cathode fails; even two problems appear in the same product
