Abstract

The invention relates to a method for improving the display quality of an active matrix organic light-emitting display, comprising an active matrix organic light-emitting display. The active matrix organic light-emitting display comprises an anode, a cathode, and an OLED disposed between the anode and the cathode. The anode is prepared with ITO, anode metal, a prone-to-be-dense metal layer and an ITO stack structure. The anode is provided with a film hole, the prone-to-be-dense metal layer in the position of the film hole reacts with air and becomes dense, and a protrusion is formed to pierce the OLED in order to prevent the anode metal from being oxidized. Thus, the display quality of a top-emission AMOLED can be effectively improved, and dark spots defects caused by short circuit of the anode and the cathode are reduced.

Description

technical field [0001] The invention relates to a method for improving the display quality of an active matrix organic light emitting display, in particular to a method for improving the display quality of an active matrix organic light emitting display with a stacked structure of ITO, anode metal and ITO. Background technique [0002] An organic light emitting display device (OLED) is an active light emitting device. Compared with the current mainstream flat-panel display technology Thin Film Transistor Liquid Crystal Display (TFT-LCD), OLED has the advantages of high contrast, wide viewing angle, low power consumption, and thinner volume. It is expected to become the next-generation flat-panel display technology after LCD. It is one of the most concerned technologies in flat panel display technology. [0003] Top emission is the development trend of AMOLED (Active Matrix / Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode), but because the top emissio...
