AI Technical Summary

Problems solved by technology

The higher the contact resistance, the greater the voltage drop and the more energy released, which will cause the device to become dark, the temperature will rise to a certain limit, and even the contact point will be damaged
The main methods to reduce contact resistance are to improve the contact surface material and increase the contact area. Among them, improving the contact surface material often introduces more expensive materials and increases the cost.

Abstract

The invention provides a manufacturing method of a metal auxiliary electrode and a display device applying the same. The manufacturing method of the metal auxiliary electrode of the display device comprises the steps of forming at least one groove at the top of a pixel definition layer of the display device; and forming a metal auxiliary electrode at the top of the pixel definition layer according to a transfer printing method. The contact area of the metal auxiliary electrode with a top electrode can be effectively increased through the groove structure, so that the contact resistance is reduced, and the conductive performance of the electrode is improved; and the technological process can be simplified through forming the metal auxiliary electrode according to the transfer printing method.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular, to a metal auxiliary electrode and a method for manufacturing a display device using the same. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) is a display lighting technology that has gradually developed in recent years, especially in the display industry. Due to its advantages of high response, high contrast, and flexibility, it is considered to have a wide range of applications prospect. In particular, top-emitting OLED devices have become the main direction of research due to their higher aperture ratio and the use of microcavity effects to optimize light extraction. Since the top emission structure is adopted, it is required that the top electrode of the OLED as the light output surface must have good light transmittance. At present, the top-emitting transparent electrodes are mostly made of thin metal, ITO, IZO and o...
