Problems solved by technology

It is very troublesome to find the short-circuit location. It is necessary to check step by step from the pins to the ITO channel with the aid of a microscope. After the ITO conductive film is pasted, the entire surface of the ITO is covered with OCA optical glue except for the exposed pins, which is difficult to check; another On the one hand, for large-scale structures, such as the case of a 98-inch capacitive touch screen, the workload of the above inspections is extremely high

Embodiment 1

[0027] figure 2 As shown, this embodiment includes several short-circuit detection reference points 1 sequentially arranged on the ITO film; each of the reference points 1 indicates a short-circuit position, and the value of the reference point 1 corresponds to the short-circuit position and the adjacent Short circuit resistance value between ITO channels.

[0028] The reference points 1 are arranged at equal intervals to facilitate short-circuit detection; the values ​​of the reference points 1 are determined according to the overall short-circuit resistance value between two adjacent channels.

[0029] Preferably, the resistance between adjacent reference points of the present application is 50-150Ω.

[0030] The two adjacent channels are:

[0031] The ground wire 5 and the first channel close to the ground wire 5;

[0032] Or the first channel and the second channel close to the ground wire 5.

[0033] Each reference point 1 is attached with a short-circuit position de...

Abstract

The invention relates to a touch screen short-circuit position detecting structure and detecting method, and belongs to the technical field of touch screen production. The touch screen short-circuit position detecting structure includes a plurality of short-circuit detecting reference points disposed on an ITO film, wherein each of the reference points indicates a short-circuit position, and the values of the reference points correspond to the short-circuit resistance between the short-circuit positions and adjacent ITO channels. According to the invention, the short-circuit inspection position of the touch screen is segmented, and the inspection range of the short-circuit position can be quickly reduced, so that the short-circuit position is further determined, and the working efficiencyis improved.

Description

technical field [0001] The invention relates to a technology in the field of touch screen production, in particular to a touch screen short circuit position detection structure and detection method. Background technique [0002] At present, capacitive touch screens transmit signals through channel lines. Channel lines are generally formed of silver paste, ITO (Indium tin oxide, indium tin oxide) and other materials. Lasers, etching, and printed lines may cause short circuits. When using a multimeter or an electric tester to test the PIN pin, there is a short circuit, and the location of the short circuit must be found and repaired. It is very troublesome to find the short-circuit location. It is necessary to check step by step from the pins to the ITO channel with the aid of a microscope. After the ITO conductive film is pasted, the entire surface of the ITO is covered with OCA optical glue except for the exposed pins, which is difficult to check; another On the one hand, f...
