Abstract

The invention discloses a display panel. The display panel comprises an organic light-emitting device and a thin film packaging layer arranged on the organic light-emitting device. The organic light-emitting device comprises an anode, the display panel comprises a frame area, the surface of the anode in the frame area is provided with a rough structure, the film packaging layer covers at least part of the rough structure, the contact area between the anode and the film packaging layer is effectively increased through the rough structure, the adhesion force of a contact interface of the anode and the film packaging layer is enhanced, the probability of film layer splitting between the anode and the film packaging layer is greatly reduced, the organic light-emitting device is prevented frombeing damaged by external water and oxygen invasion to the inner portion of the display panel, the service performance of the display panel is improved, and the service life of the display panel is prolonged.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) has received great attention from academia and industry because of its great development potential in the direction of solid-state lighting and flat panel display. OLED panels can be made lighter and thinner, and more and more mobile phone manufacturers choose OLED panels as displays. Narrow Border has become a popular design for mobile phone screens in recent years. [0003] OLED panels need to be stored in a high-temperature and high-humidity environment (such as 85°C / 85% humidity) or placed in a lit state for a period of time for reliability testing. A conventional OLED panel includes an array layer, a planar layer, an OLED device, and a flexible encapsulation layer. The anode of the OLED device includes a bottom ITO (Indium-Tin Oxide, indium tin ...
