Embodiment Construction

[0013] A kind of method of repairing electronic display screen circuit with ITO indium tin oxide electrode described in the present invention, first use No. 11 blades to cut off the protective layer and isolation layer on the display screen, expose the damaged display screen circuit, and stick the After the residue attached to the glass is polished and cleaned, place the IT0 wire on the scraped place, use the scraper to form a groove on the display screen according to the circuit repair trend, and use a scraper (pointed-shaped Such as figure 1 As shown) stick it on the IT0 indium tin oxide wire and rub it back and forth to make the nano-indium tin oxide wire rub against and generate heat, and use the friction heat to turn the IT0 wire into a molten IT0 indium tin oxide film, and at the same time use a scraper to oxidize the molten IT0 The indium tin film is filled in the groove to form a continuous IT0 indium tin oxide electrode to repair the electronic display circuit. Finall...

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...
