The touch screen is now very familiar with our lives, the mobile phones we use are generally touch screens, and now, like some televisions and computers, are already using touch screens, and the use of touch screens, in terms of touch screens, has become increasingly widespread in their application, and the touch screens have played a very important role in industry, as well as in services and military and circulation industries。
Moreover, on many occasions, the use of touch screens or their large-scale use can be said to have become a direct link to human dialogue in everyday life and to have become popular in the use of mobile phones and households. But after all, glass as a dominant structure is generally fragile and prone to some malfunctions, and here is a brief introduction to some of the malfunctions and touch screen maintenance techniques that may occur。
Touch glass failure maintenance
The most frequent contact with the finger is the touch glass, i. E., the surface layer of the touch screen, which is typically caused mainly by the use of too rough a movement of people, and the carelessness of transport is also one of the unintended causes of damage to the touch screen, but the problem of transportation is generally caused by damage to the touchglass, which, if the touch glass is damaged, needs to be replaced during maintenance, and the touch screens produced by the various producers are different, so there is an emulation process at the time of replacement, which becomes much simpler when the touch screens are opened, and if they are not, they need to be replaced。
Touch screen circuit board failure maintenance
This problem will not be so many, but it will be a more troublesome failure because, while maintaining this failure, the maintenance staff must have the basics of repair and have excellent hands-on skills and experience in the maintenance of touch screens. Because the touch screen is now based on a high-level dsp integrated chip as the control core of the whole touch screen, it is important that it be strictly compared and maintained with the circuit drawings provided by the touch screen factory, usually the cause of mechanical failures such as crystallization and peripheral ic。
Frequent faults in the touch screens, inter alia, touch failures and communication failures, are generally subject to modifications to circuit drawings during maintenance, many of which are due to poor contact with the touch screens, so it is important that the circuits are checked very carefully during maintenance, with the option of returning to the factory or replacing parts if necessary。
