Touch Screen

Is it possible to use a thicker micro glass?

Abstract

An introduction into the various common types of touch screen technology and the method of their operation. Strengths and weaknesses of each technology will also be discussed to provide a better understanding as to which type would be best to use in any given application.

Decibel (dB) - a unit of power loss or attenuation used in EMI/RFI shielding:

1 decibel = 10 log (Power in/Power out).

A 3dB loss is a fifty percent power reduction.

Drift - a gradual loss of accuracy in the alignment of a touchscreen system. Over time, touches to the screen will gradually drift, or move away, from their proper on-screen targets. If the alignment of a touchscreen becomes poor, the touchscreen will need to be calibrated to restore proper alignment.
