Method for repairing circuit of electronic display screen by using ITO (Indium Tin Oxide) electrode

Abstract

The invention discloses a method for repairing a circuit of an electronic display screen by using an IT0 electrode, which comprises the following steps of: firstly, cutting a protective layer and an isolating layer on a display screen by using a blade, exposing the damaged display screen circuit, grinding, polishing and cleaning residues adhered to glass, putting an IT0 wire at a scraped part, forming a groove in a display screen according to a line repair trend line by using a scraper, attaching the scraper to the IT0 wire to rub back and forth at the damaged line, so that the nanometer indium tin oxide wire generates heat by friction, the IT0 wire is changed into a molten IT0 indium tin oxide film by using the friction heat; and meanwhile, filling the molten IT0 film in the groove by using the scraper, and forming a continuous IT0 electrode to repair the circuit of the electronic display screen. According to the method for repairing the circuit of the electronic display screen through the IT0 electrode, the repairing process is simple, the repairing time is short, the repairing efficiency is high, and the repairing effect is good.

Description

technical field [0001] The invention relates to an electronic display screen, in particular to a method for repairing an electronic display screen by using an ITO electrode, especially a method for repairing a circuit of a mobile phone touch electronic display screen by using an ITO electrode. Background technique [0002] Traditional electronic industry display screens include TV LCD screens, industrial screens, flat panel LCD screens, mobile phone OLED displays and TP touch screens. At present, there are mainly two types of touch screens, one mainly includes resistive type, surface capacitive type and inductive capacitive type; the other type includes surface acoustic wave type, infrared type and bending wave type. The first type is the ITO indium tin oxide type. Since indium tin oxide is a highly transparent conductor, the first type accounts for more than 80% of the total, and is currently the most widely used. Since most of the original manufacturers use IT0 indium tin...

AI Technical Summary

Problems solved by technology

[0003] When the display screens in the above-mentioned prior art are damaged or corroded by water, the display screens will become blurred and will no longer be usable. A large number of glass display screens cannot be repaired but can only be discarded and discarded. There is no way to repair it mechanically, even if it needs to be relaid, the cost of repairing is about 600 times higher than the cost of producing a display screen (the average cost of a new display screen is more than 1,000 yuan), which will not only cause economic losses, but also cause serious pollution to the environment.
