Abstract

The invention provides an OLED display panel, a preparation method thereof and a display device. The OLED display panel comprises a transparent substrate layer and a display base material which are stacked; the display base material comprises a switching device layer, an organic light-emitting device layer and a packaging layer which are stacked; a via hole is formed in the display base material,and shading layers are arranged on the side, away from the transparent substrate layer, of the display base material and in the via hole; the shading layers are each provided with a first light-transmitting area in an area at the bottom of the via hole, and the first light-transmitting area is used for being matched with the design size of the camera; the area, located on the side, away from the transparent substrate layer, of the display base material in the shading layers comprises a plurality of second light-transmitting areas, and the multiple second light-transmitting areas are matched with the multiple effective light-emitting areas of the organic light-emitting device layer respectively. On the basis of not influencing the vertical emission of the light of the organic electroluminescent layer, the shading layers can effectively prevent the light from being emitted from the side surface, and can effectively prevent the interference of the light emission of the pixel region on thelight collected by the camera, thereby improving the imaging quality.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to an OLED display panel, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode) display panels have the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, fast response, etc., and are popular in the market. However, while the OLED display panel has a wide viewing angle, it also brings some disadvantages. For example, when a user uses a smart terminal device with an OLED display panel, other people close to the user can see the content displayed on the display screen, which may easily cause privacy leakage. . [0003] Moreover, with the application of full-screen display panels, this requires a very mature under-screen camera technology. However, when the camera located under the full-screen display panel starts shooting, the lumin...
