Embodiment 1

[0034] Such as image 3 As shown, in this embodiment, the array substrate 10 of the present invention includes a substrate 110 and a pixel definition layer 120 .

[0035] The array substrate 10 includes a light-emitting area 101 and a non-light-emitting area 102 surrounding the light-emitting area 101 , and the light-emitting area 101 is used to provide a display image.

[0036] Such as Figure 4 As shown, the pixel definition layer 120 is disposed on the substrate 110, and its material is made of hydrophobic and oleophobic materials, such as fluorine-containing materials. In order to receive the ink used to emit light, the pixel definition layer 120 is provided with several openings 121 corresponding to the light emitting area 101, wherein the pixel definition layer 120 between adjacent openings 121 is a barrier wall 122 In the prior art, the inkjet printing method is generally used to drop the ink into the opening 121, but due to the improvement of the resolution and the r...

Embodiment 2

[0038] In this embodiment, the array substrate 10 of the present invention includes a substrate 110 and a pixel definition layer 120 .

[0039] The array substrate 10 includes a light-emitting area 101 and a non-light-emitting area 102 surrounding the light-emitting area 101 , and the light-emitting area 101 is used to provide a display image.

[0040] The pixel definition layer 120 is disposed on the substrate 110 and its material is made of hydrophobic and oleophobic materials, such as fluorine-containing materials. Such as Figure 4 As shown, in order to receive the ink for emitting light, the pixel definition layer 120 is provided with several openings 121 corresponding to the light emitting area 101, wherein the pixel definition layer 120 between adjacent openings 121 is For the retaining wall 122, in the prior art, ink is generally dropped into the opening 121 by means of inkjet printing, but due to the improvement of the resolution and the reduction of the pixel size, ...

Abstract

The invention discloses an array substrate, a preparation method thereof and a display device. The array substrate comprises a substrate and a pixel definition layer, wherein the pixel definition layer is arranged on the substrate; the pixel definition layer comprises open pores and a retaining wall surrounding the open pore; the retaining wall corresponds to a non-light-emitting area, and the open pore corresponds to a light-emitting area; and a groove is formed in the side, away from the substrate, of the retaining wall between every two adjacent open pores. The array substrate, the preparation method of the array substrate and the display device have the advantages that the grooves are formed in the retaining walls between the open pores of the pixel definition layer, so that poor display caused by ink color mixing is effectively reduced.

Description

technical field [0001] The invention relates to the display field, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] AMOLED (English: Active-matrix organic light-emitting diode, Chinese translation: active matrix organic light-emitting diode or active matrix organic light-emitting diode) is a display technology. Among them, OLED (organic light-emitting diode) is a specific type of thin-film display technology: organic electroluminescent display; AM (active matrix or active matrix) refers to the pixel addressing technology behind it. At present, AMOLED technology is mainly used in smart phones, and continues to develop in the direction of low power consumption, low cost, and large size. [0003] Such as figure 1 As shown, inkjet printing technology has a good application prospect in the preparation of organic functional layers of AMOLED display devices. Inkjet printing technology is to directly drop the i...
