Problems solved by technology
[0003] At present, the mainstream direction of small-sized mobile phone display screens in the market is full-screen display, and the factors that affect the full-screen display effect include the configuration of various sensing devices and the size of the frame area. By reducing the size of the frame area, the screen size of the display screen can be effectively increased. However, in order to ensure the packaging effect of the display screen in the prior art, more frame glue is used for lamination, which makes it difficult to reduce the size of the display frame area, and limits the development of full screen technology.

The present invention provides an organic light-emitting diode display panel and a manufacturing method thereof. A first groove surrounding a wiring layer is formed by etching the thin film transistorlayer, the first groove is filled with the first packaging layer, the packaging effect of the organic light-emitting diode display panel is improved, in addition, the pattern of the first groove is designed to have the long perimeter, not only is the packaging interface of the first packaging layer increased, but also the diffusion paths of moisture and oxygen are increased, and the packaging effect is further improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display panel and a manufacturing method thereof. Background technique [0002] As a new generation of display technology, organic light-emitting diode (OLED) display panels have the advantages of low power consumption, high color gamut, high brightness, high resolution, wide viewing angle, high response speed, etc., and are widely accepted by the market. of favor. [0003] At present, the mainstream direction of small-sized mobile phone display screens in the market is full-screen display, and the factors that affect the full-screen display effect include the configuration of various sensing devices and the size of the frame area. By reducing the size of the frame area, the screen size of the display screen can be effectively increased. However, in order to ensure the packaging effect of the display screen in the prior art, more frame glue is us...
