Folio -Maintenance Tips of Capacitive Touchscreen - Folio 100 General

1. How to Maintenance Capacitive Touchscreen?
There are 6 main factors would arouse capacitive touchscreen failure in daily life.
(1) Magnetic field
Keep away from magnetic field, especially for electromagnetic field! Stay away from magnetic screw and any other magnetic things. Even a little magnet would result in the temporary failure of touchscreen. Badly, it may cause permanent damage for capacitive screen. Don't close to baffle box and let alone leave it on baffle box casually after go back home.
(2) Static Electricity
Use a leather case! Static electricity is a big enemy of touchscreen, which may puncture the touchscreen. Although the glass surface of touchscreen adopts anti-static processing, it doesn't mean the capacitive screen can stand all the static electricity from human body. Actually leather case is anti-static, which is your better choice.
(3) Conductive Medium
Clean your hands before touch the screen! Actually the grease and sweat in hand is conductive medium, which is easy to form a conductive layer, so as to arouse inaccurate location in touch screen.
If the screen is covered by oil or water, it will floating and cannot respond normally.
(4) Unstable Voltage
Charge immediately when power falls below 20%. When you touch the screen, your finger will absorb subtle electricity. At this time, the electricity from 4 corners of the screen will be transmitted to the point where you touch. The touchscreen under the condition of unstable voltage will float or "die".
(5) High Temperature
If the temperature of capacitive touchscreen reaches 40-degree, your touchscreen will be inaccurate. Worse still, if you let your touchscreen have a sunbath in high temperature for a long time, it will be over. Hence, the ideal working temperature is from 0 to 35 degree with 5% humidity at least, according to the characteristics of touchscreen.
Advice: If temperature of your screen rises too high when you charge, please stop charging and wait for a moment until the temperature falls.
(6) Hard Force
As we all know, the silica glass in surface of capacitive touchscreen is scratch-resistant, but no ruler without an exception. If you punch a hole in a touchscreen by fingernail or hard object by accident, the inner ITO layers of touchscreen will be damaged. Naturally capacitive touchscreen will be on strike.
2. Maintenance of Capacitive Touchscreen — Summary
In daily life, the problems of capacitive touchscreen are common and easy to be ignored. The maintenance of capacitive touchscreen will influence the life of the capacitive touch screen directly. Once there is something wrong with your capacitive touchscreen, please calm down first and think about whether the problems are caused by those factors listed above. And then find the solution of problems.

Capacitive touch screens are curved or flat glass substrates coated with a transparent metal oxide. A voltage is applied to the corners of the overlay creating a minute uniform electric field. A bare finger draws current from each corner of the electric field, creating a voltage drop that is measured to determine touch location.
So,
Clean often using microfiber cloth is the best way.
Turn off the unit if we need to clean the screen with a damp cloth.
Liquid such as grease or water dried on the screen will left a conductive mark that may cause lagging.
Trapped dirt hurts -Bad luck if you get dirt or dust or liquid trapped underneath the screen surround. You’ll recognise the symptoms of ‘touchscreen trauma’ when it starts selecting items for you by itself.
