Abstract

The invention is suitable for the flat panel display technology field, and provides a modified ITO anode and a preparation method and applications thereof. The preparation method comprises the following steps: providing an ITO substrate, the ITO substrate comprising a substrate and an ITO film formed on the substrate through deposition, and cleaning and drying the ITO substrate in sequence; taking an HF solution or an HC1 solution as an electrolyte, the ITO substrate as an electrolytic bath anode and a molybdenum electrode as an electrolytic bath cathode, and then placing the ITO substrate and the molybdenum electrode side by side in a reaction container, conducting constant voltage electrochemical processing on the ITO film, and obtaining a surface-modified ITO electrode; and cleaning and drying the surface-modified ITO electrode.

Description

technical field [0001] The invention belongs to the technical field of flat panel display, and in particular relates to a modified ITO anode and a preparation method and application thereof. Background technique [0002] Organic electroluminescent device is a new type of flat panel display device. Compared with liquid crystal display device (LCD), it has the characteristics of high brightness, active light emission, wide viewing angle and fast response speed. It is a rising star in the field of flat panel display, showing development and application prospects. The luminescent principle of organic electroluminescent devices is that under the action of an external electric field, carriers are injected from the electrodes into the light-emitting layer to recombine and emit light. Organic electroluminescent devices require anode materials with high work function and good light transmittance, so as to facilitate light emission from the device. [0003] At present, the anode mat...
