7 Projected Capacitive Touch Screen

7.1

7.1 General Information

The use of projected-capacitive touch screens has all the benefits a normal capacitive touch screen has:

• fast processing of touch information

• high sensitivity (use with hands, conductive pencils and also with thin gloves)

• high resolution

• improved legibility and display brightness due to optimal light transmission

• Anti-glare-surface

In addition the technology of projected-capacitive touch screens is characterized by significant higher ro-

bustness and stability, because the active touch surface – different from common capacitive touch

screens which were used until now - is located on the back side of the touch screen. Thus the active

touch surface is not touched directly anymore and therefore will not wear off by normal use. As most of

the surface contaminations do not cause an interference of the touch screen, this technology can be

used in public or under severe environmental conditions.

7.2 Instructions for Using the Touch Screen

The touch screen responds to the lightest touches. The touch with only one finger is like the use of the

left mouse button. The use of the touch screen with two fingers generates a zoom if the fingers are

brought together or pulled apart. With a circular motion of the fingers the element on the display can be

rotated. This function must be supported by either the operating system or by the application.

7.3 Cleaning Instructions

Always turn off the system before cleaning.

WARNING

The glass surface of your Touch Screen should be cleaned with a mild, abrasive free,

commercially available glass cleaning product. All pH neutral materials (pH 6 to 8) are

good for cleaning. Cleaners with pH values 9 to 10 are not recommended. Cleaning with

water and isopropyl alcohol is possible as well. Do not use solvents containing acetic acid.

Use a soft, fine-meshed cloth to clean the surface. Dampen the cloth slightly and then

clean the screen.

NOTE

A wrong maintenance may cause damages to the screen, which are not covered by

warranty.
