Problems solved by technology

[0005] The invention provides an OLED display panel. By adding a polymer layer between the retaining wall and the inorganic film layer of the encapsulation layer, the polymer layer forms chemical bonds or physical adhesion with the retaining wall and the inorganic film layer, thereby strengthening the connection between the retaining wall and the inorganic film layer. The bonding force between the film layers is to solve the technical problem that the existing OLED display panel is easy to detach due to the poor bonding force between the retaining wall and the inorganic film layer, thereby affecting the performance of the OLED device

Abstract

The invention provides an OLED display panel and a manufacturing method thereof. The OLED display panel comprises a display region and a non-display region outside the display region. The non-displayregion is provided with a retaining wall, and the OLED display panel comprises a packaging layer, and a polymer layer is formed between the retaining wall and the packaging layer for enhancing the bonding force between the retaining wall and the packaging layer. The OLED display panel and the manufacturing method thereof provided by the invention are advantageous in that the binding force betweenthe retaining wall and the packaging layer can be enhanced, the packaging effect of the packaging layer can be improved, so that external water oxygen particles can be prevented from entering the OLEDdisplay panel to corrode the OLED device more effectively, and the service lifetime of the OLED display panel is prolonged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Flexible OLED display is currently a hot development direction in the display industry due to its low power consumption, high resolution, fast response, and bendability. Among them, the packaging layer of the flexible OLED device is generally an inorganic / organic film layer with a laminated structure. [0003] In order to prevent the organic film from flowing out of the coverage area of ​​the inorganic film, one or more barrier walls are usually designed. During the manufacturing process, the retaining wall is in direct contact with the first inorganic film layer of the encapsulation layer, but the bonding force between the two is poor and they are easy to separate. [0004] Therefore, it is necessary to provide a new display panel to solve the above problems. Contents of the invention ...
