1. In the daily use of the equipment, try to prevent frequent power off and off, and sudden power failure during operation will cause certain damage to electronic components and hard disk errors; In terms of power supply, keep operating in a stable voltage environment, too low voltage, too high voltage will affect the function of the equipment, but also affect the use experience and life.
2. The equipment is placed in a dry and ventilated environment, and the electronic equipment is sensitive to humidity, once the internal moisture of the machine and equipment will affect the circuit problem, form a short circuit in the line, and affect the service life of the equipment, so the operating environment of the equipment should also pay attention to maintaining dry ventilation.
3. The contact inquiry all-in-one machine, running in public places for a long time, can not prevent dust, the accumulated dust will make the contact screen appear static electricity, will affect the use of the contact screen, affect the accuracy of contact, and need to regularly clean the equipment screen and body. In cleaning, it should be noted that do not use corrosive detergents such as chemical detergents, choose a soft cloth, wring out the water and wipe it gently to prevent scratches on the screen and ensure that the device is clean and boring.

The driving principle of a capacitive touch screen
1. Projective capacitive contacts
Although the basic structure and operating principle of the projection capacitive contact screen is the same as that of the four-wire impedance film, the projection capacitive impedance film does not pass through the contact field, but captures the change of capacitance between the electrodes. Generally speaking, when using the form of capacitive sensor, it can almost ...
