In recent years, multi-touch technology has managed to revolutionize the HMI industry with smartphones, tablets and the like and to inspire the wider society.
Which touch screen for multitouch?
Multitouch in itself means that two or more touch points can trigger touches on a panel at the same time…

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…

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.

Hydrofluoric acid is a solution of hydrogen fluoride in water. While it is extremely corrosive and dangerous to handle, it is technically a weak acid. Hydrogen fluoride, often in the aqueous form as hydrofluoric acid, is a valued source of fluorine, being the precursor to numerous pharmaceuticals (…

As a rough guideline, you can calculate $6400 one-time costs. In addition, there is a purchase of about 50 pieces of your individual touchscreens.
These values can change if special customer-specific options have been selected, such as:
Optical anti-reflective coatings
Polarizer
Special substrate…

If you operate the controller via USB, no external power supply is necessary. The controller is powered directly via the USB bus. When operating via RS232, you need an external power supply of +5V.
With our standard controllers for 4.5 and 8 analog resistive touchscreens, pin 4 must be supplied…
