Problems solved by technology

The above process can only clean the ITO surface and remove the stains on the ITO surface, but cannot carry out targeted hydrophilic treatment on the ITO, resulting in the weak hydrophilicity of the ITO surface

Abstract

The invention relates to the technical field of liquid crystal display, in particular to a hydrophilic treatment method of an ITO (indium tin oxide) substrate. The hydrophilic treatment method comprises the step of treating the ITO substrate by a mixed solution of concentrated acid and hydrogen peroxide. By testing the optical and electrical properties of a thin film prepared by the ITO substratesubjected to hydrophilic treatment, the result shows that the carrier transmission efficiency is improved; further, the electrical optical efficiency of an OLED (organic light emitting diode) device is improved; the resistance rate of the thin film is low; the heating is low; the stability of the OLED device is greatly improved; the service life of the OLED device is greatly prolonged; the absorption spectrum and the emission spectrum of the thin film are enhanced; the luminous efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a hydrophilic treatment method for an ITO substrate. Background technique [0002] OLED has the advantages of thinness, surface emission, self-illumination, flexibility, bendability, transparency, etc., and has broad application prospects in the fields of lighting and display. The organic layer of the OLED device is an organic chemical material, and the effective contact between the organic film and the substrate has a great influence on the transmission of photoelectrons. [0003] At present, the treatment methods of ITO are mainly divided into physical methods and chemical methods. The physical method is mainly plasma treatment, including O 2 Plasma bombardment, UV-ozone, oxygen glow discharge (O-GDT), etc.; chemical methods mainly use chemical reagents to clean the ITO surface to remove ITO surface stains. [0004] At present, the chemical process of ITO glas...
