Advantages of SP-ITO Touch Screen
1.Realize process simplification: The new material application process can directly simplify more
than half of the traditional process, and the yield rate is greatly improved.
2. Cost down:
a. The application of new materials can eliminate all silver paste manufacturing processes and reduce the production cost of products.
b. The application of new materials can reduce the investment of production
personnel by more than half compared with the traditional production process.

Installation way of Touch Panel
Note 1: In order to make a touch panel work normally, please make sure that the host device is grounded.
Note 2: All environmental characteristics listed above should be less than 1 atmospheric pressure.
Note 3: The touch panel must be assembled with LCD panel by VHB or other materials, the control board should be fixed on LCM bezel or other mechanical parts of the system and then be grounded; In ESD test, the touch panel should work normally and there should be no damage to the appearance, when no static electricity discharges. However, irregular changes like display flickering are acceptable when static electricity discharges.
Note4: The touch panel may be damaged functionally or work unstably if the panel are not be grounded though your system to earth.
Note5: In order to make a touch panel work normally, power supply or power adapter has to conform to IEC 62684.

Capacitive Touch Panel:
Capacitive Touch Panel is to use the working current of induction of human body.The operational principle of the projected capacitive touch panel: There are two layers of the ITO layer under the surface of glass. This ITO layer respectively forms the electric field of X axis and Y axis, which can keep balance by crossing the surface of the class. Once the fingers approach the glass surface, the fingers and the electrode X axis or Y axis will form a new electric field, which can make the local capacitance change. Then the controller will determine the location based on capacitance changes.
