Problems solved by technology

As the resolution of OLED displays is getting higher and higher, the distance between two adjacent light-emitting devices is gradually reduced, so that when making pixelated light-emitting devices, the light-emitting film layers of two adjacent light-emitting devices are in the pixel defining layer. Superimposed on each other, so that when the screen is displayed, the light emitted by the light-emitting film layer between two adjacent pixels will produce mutual crosstalk, resulting in bad pictures such as color cast in the displayed picture

Abstract

The invention discloses an OLED display substrate and a manufacturing method, and a display apparatus, relates to the technical field of the OLED, and aims to lower mutual crosstalk degree between twoadjacent pixel light rays in image display so as to weaken the color cast problem of the displayed image. The OLED display substrate comprises a substrate and a plurality of light emitting devices formed on the substrate; a pixel definition layer is formed between two adjacent light emitting devices; an accommodating part used for accommodating the overlaid region of the two adjacent light-emitting devices is formed on the surface, deviated from the substrate, of each pixel definition layer; and the bearing surface of the accommodating part and the surface, deviated from the substrate, of thecorresponding pixel definition layer are located in different planes. The manufacturing method of the OLED display substrate is used for manufacturing the OLED display substrate. The OLED display substrate and the manufacturing method thereof, and the display apparatus are used in the display technology.

Description

technical field [0001] The invention relates to the technical field of OLEDs, in particular to an OLED display substrate, a manufacturing method, and a display device. Background technique [0002] Organic Light-Emitting Display (OLED for short) is a high-contrast flexible display device, which has the characteristics of self-illumination, wide viewing angle, and fast response. [0003] Existing OLED displays mainly include OLED display substrates, such as figure 1 As shown, the OLED display substrate includes pixelated light-emitting devices formed on the surface of the base substrate by a film-forming process, and two adjacent light-emitting devices are defined by a pixel-defining layer. As the resolution of OLED displays is getting higher and higher, the distance between two adjacent light-emitting devices is gradually reduced, so that when making pixelated light-emitting devices, the light-emitting film layers of two adjacent light-emitting devices are in the pixel defi...
