II、Analysis of the reasons for the failure of the car navigation touch screen.
The car navigation touch screen is extremely static: it is very easy to puncture the capacitive screen. Although the glass on the surface of the car's navigation touch screen is treated with a certain amount of anti-static electricity, it does not mean that it can resist the static electricity of the body during the winter.
The car navigation touch screen is afraid of oil, sweat and other conductive media: covering on the screen will form a conductive layer, which will cause the screen to move hand washing, drying and reuse.
Car navigation touch screen is afraid of "high" : "high" temperature here is not in the fire to roast, but temperature about 40 degrees, is likely to cause slips capacitance screen, at this temperature for a long time, the capacitance screen will die Don't sunbathing, don't use in high temperature in the sun for a long time.
The car navigation touch screen is afraid of the magnetic field: especially the electromagnetic field, the small magnet on the capacitor screen for a while, the capacitor screen will temporarily disable.
