oled display panel

Abstract

The present application discloses an OLED display panel, which includes a display area and a non-display area, and also includes an array substrate, a first barrier wall, a second barrier wall, multiple metal traces, multiple first grooves, and a thin film encapsulation layer; Wherein, the metal wiring layer is located in the fan-out wiring area of ​​the array substrate close to the lower frame, part of the metal wiring is arranged along a direction perpendicular to the first retaining wall, and the other part of the metal wiring is The included angle with the first retaining wall is an acute angle; a plurality of the first grooves are arranged in the fan-out wiring area, and the first grooves are arranged along the direction of the metal wiring; the The part of the array substrate corresponding to the second region is further provided with a plurality of second grooves, and the second grooves are arranged along a direction perpendicular to the first barrier wall.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel. Background technique [0002] In flat panel display technology, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) devices have been widely used due to their advantages of light weight, thin thickness, bendability, and wide viewing angle. However, the light-emitting unit of the OLED device is sensitive to water and oxygen, and needs to be packaged and protected. In order to achieve the purpose of flexible display, the method of thin-film packaging is generally adopted, that is, packaging in the way of stacking inorganic / organic / inorganic film layers. Among them, the inorganic layer plays the role of blocking water and oxygen, and the organic layer is to coat the particles and relieve the stress when the device is bent. The organic layer has fluidity, and in order to confine it to a specific area, one or several barrier walls (Dam...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides an OLED display panel, which can effectively improve the uniformity of the film formation of the thin-film encapsulation organic layer at the lower frame, so as to solve the problem of the existing OLED display panel. In the lower frame area where there are many wires, the surface morphology of the inorganic / metal film layer is different at different positions, which makes the fluidity of the thin-film encapsulated organic layer different at positions with different surface morphology, which makes the thin-film encapsulated organic layer very likely. Diffusion will occur across the retaining wall, resulting in the technical problem of packaging failure after the organic film contacts the outside world
