AI Technical Summary

Problems solved by technology

Considering that the metal traces in the touch function layer are likely to cause short circuits when prepared on a substrate with grooves, the grooves need to be filled. However, during the filling process, the gas is easy to accumulate in the grooves, resulting in subsequent coating. Inhomogeneous coating occurs due to the accumulation of gas in the groove during the cloth process

Abstract

The invention provides a display device, a display panel and a manufacturing method of the display panel. The display panel comprises an opening area, a peripheral area and a display area, wherein theperipheral area surrounds at least one part of the opening area. The display panel further comprises a thin film transistor substrate, a plurality of annular retaining walls and a filling layer, wherein the plurality of annular retaining walls are arranged at the part, which corresponds to the peripheral area, of the thin film transistor substrate, the annular retaining walls are arranged aroundthe opening area, and any one annular retaining wall is provided with at least one opening; and the filling layer is arranged in the peripheral area. The display device, the display panel and the manufacturing method thereof provided by the invention are used for improving the phenomenon of non-uniform coating caused by gas accumulation in the groove in the coating process.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display devices have the advantages of self-illumination, high contrast, wide viewing angle, low power consumption and bendability, and are favored by consumers and developers. Flexible OLED display devices are also gradually occupying the market due to their flexible, thin and light features, and high screen-to-body ratio and even full-screen displays have become the focus of industry and academia. In addition to the display area of ​​the display device, components such as cameras, earpieces, and microphones also occupy a certain proportion of the screen. In order to increase the screen-to-body ratio of the display device, the current common method is to use laser cutting technology to place the camera in the display area. However, aft...
