9 Inch Touch Screen Panel

Touch operation, no action, that is, with your fingers to touch the , but the screen does

not make touch response.

It is because of the capacitive screen works, which leads to the existence of a \"drift\" phenomenon.

Clarify the working principle of the capacitive screen; it is easy to know the cause of the capacitive

screen \"drift\".



Some main reason is as follows:

1, electrostatic

Dependent electric field due to capacitive screen positioning, so very slight static, it will lead to the

occurrence of the phenomenon of \"drift\". If electrostatic discharge occurs, and may even

permanently damage the capacitive screen.



2, the magnetic field

The magnetic field produces an electric field; capacitive touch panel in a strong magnetic field will

produce the phenomenon of \"drift\". The magnetic field is too strong or prolonged in a strong

magnetic field, perhaps even permanent damage to the capacitive screen.



3, the conductive material

Attached to the conductive material on the screen, such as oil, perspiration, water vapor will lead

to the occurrence of the phenomenon of \"drift\" If you accidentally flow into the inside of the screen,

and may even permanent damage to the capacitive touch panel and other components.
