Abstract

The invention provides a display panel manufacturing method and a display panel. The display panel manufacturing method comprises the steps: forming a double-layer conductive layer covering a displayregion and an edge region during the manufacturing of source and drain electrodes of a display panel, and then carrying out continuous etching on the double-layer conductive layer twice to form a source-drain electrode with double conductive layers and an edge electrode with a single conductive layer, wherein the double-conductive layer structure of the source-drain electrode improves the conductivity of the source-drain electrode. According to the manufacturing method of the display panel, the manufacturing process of the edge electrode and the manufacturing process of the source-drain electrode are combined, and the edge electrode and the source-drain electrode are manufactured at the same time through the same deposition and etching process, so that the operation of independently manufacturing the edge electrode is omitted, the manufacturing process of the display panel is simplified, and the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for manufacturing a display panel and a display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display has performance characteristics such as self-illumination, low driving voltage, high luminous efficiency, short response time, high contrast, wide viewing angle, etc., and can realize flexible display and large-area full-color display, etc. Advantages, it is considered by the industry to be the display with the most potential for development. [0003] OLED display panels usually have a display area and an edge area. The display area is mainly used to realize the display function of the display panel. The edge area is provided with edge electrodes, such as bonding traces, bonding pads, etc., to connect the display area with external signal components. Electrically connected. The layered structure of the...
