Abstract

The invention provides an OLED display panel and a preparation method thereof. The OLED display panel comprises a display area and an electronic element setting area corresponding to the setting position of an electronic element, and the OLED display panel comprises a substrate, a driving circuit layer, a pixel definition layer, a blocking member, a first inorganic packaging layer, an organic packaging layer and a second inorganic packaging layer which are arranged in a stacked manner; wherein the pixel definition layer comprises a plurality of opening areas and a plurality of pixel definitionareas, and sub-pixels are formed in the opening areas; the blocking component is formed in the electronic element setting area and is arranged corresponding to the area without the sub-pixels; a first inorganic encapsulation layer formed on the sub-pixels and extending to cover the pixel definition layer and the blocking member; the organic packaging layer is formed on the first inorganic packaging layer and is arranged corresponding to the opening area in the electronic element arrangement area and the display area; the second inorganic packaging layer is formed on the organic encapsulationlayer and extends to cover the first inorganic packaging layer. By reducing the number of film layers above the pixel definition layer, the shooting effect of the under-screen camera is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a preparation method thereof. Background technique [0002] With the development of full-screen technology, the technology of placing electronic components such as cameras under the display is a development trend. In the production process of the existing OLED display panel, the display area and the camera area under the screen need to be packaged. However, after packaging, the area above the camera has many layers of film, and the external light transmittance is low, resulting in poor shooting effect of the camera. . [0003] Therefore, the existing OLED display panel has the technical problem of poor shooting effect of the camera under the screen, which needs to be improved. Contents of the invention [0004] The invention provides an OLED display panel and a preparation method thereof, so as to alleviate the technical problem of poor shooting eff...
