Problems solved by technology

[0005] like figure 1 As shown, in the current OLED display panel, most OLED display panels use ITO material to form the metal anode layer. After the flexible display panel is bent many times, it is prone to fracture, and the conductivity of the fracture area is low. During normal use, the fracture area cannot emit light normally, which further affects the display effect of the overall OLED display panel and causes optical performance degradation. , and display defects

Abstract

The invention relates to a preparation method of an anode of a flexible OLED display panel and a preparation method of the display panel. The preparation method of the anode comprises that a metal stretched protective layer is deposited in the surface of an organic light emitting layer; a transparent conductive film layer is formed in the surface of the metal stretched protective layer by vapor plating or re-sputtering; and the transparent conductive film layer is combined with the metal stretched protective layer to form the anode of the display panel. When the display panel is in a bent state, fracture of the transparent conductive film layer in the display panel is delayed, and the service life of the whole display panel in the bent state is prolonged; when the transparent conductive film layer of the flexible display panel has cracks, the metal stretched protective layer has good conductivity, and a fractured area of the transparent conductive film layer can realize a conductive performance via the metal stretched protective layer, normal display of the fractured area is protected, the optical fraction defective is reduced, and the total visual feeling is improved.

Description

Technical field [0001] The present invention relates to the technical field of semiconductor display, in particular to a method for preparing an anode of a flexible OLED display panel and a method for preparing a display panel. Background technique [0002] Organic Light-Emitting Diode (OLED) has excellent display performance, self-luminous, simple structure, ultra-light and thin, fast response speed, wide viewing angle, low power consumption and flexible display. [0003] The light-emitting principle of OLED is the phenomenon that organic semiconductor materials and light-emitting materials are driven by an electric field to cause light emission through carrier injection and recombination. Specifically, OLED display devices usually use ITO pixel electrodes and metal electrodes as the anode and cathode of the device, respectively. Under a certain voltage drive, electrons and holes are injected from the cathode and anode to the electron transport layer and hole transport layer, resp...
