Capacitive Touchscreens

Operating principle

A capacitive touchscreen consists of a conductive layer on the front side. A voltage is impressed on the edges, which generates a homogenous electrical field. By touching the surface with the finger, a charge transfer is activated.  By the resulting current, the position of the finger can be defined. 

In addition, we offer optical bonding technology both under vacuum and by
means of wet bonding. Here, under clean room conditions both touchscreen
and glass are bonded or adhesively bonded to the display.

specification:

storage temperature: -40 to 90°C at 10-90% rel. humidity
transparency: > 90%
linearity: X / Y: </= 1%
bounce time: </= 15ms
surface hardness: 7H
durability test: 200.000.000 on one point
advantages: disadvantages:
extremely resistant can be used only with the finger or with a capacitive medium
good optical transparency deep scratches can disturb the functions
high resolution, very precise
