Touch Screens
There are two types of touch screens for the RealPOS X-Series Display (5968):
• Projected Capacitive (PCap) Touch Screen
• Resistive Touch Screen
Projected Capacitive Touch Screen
PCap touch screens have all the benefits of normal capacitive touch screens and more.
• Fast processing of tough information
• High sensitivity (use conductive pencils, with hands, and with thin gloves.
• Multi-touch capability (10-finger)
• High resolution
• Improved legibility and display brightness due to optimal light transmission
• Anti-glare surface
In addition, the technology of PCap touch screens is characterized by significantly
higher robustness and stability than common capacitive touch screens because the
active touch surface is located on the back side of the touch screen. instead of the front
side. Therefore, the active surface is not directly touched and does not wear off by
normal use.
Since most surface contamination do not cause interference to the touch screen the
RealPOS X-Series Display can be used in public or severe environmental conditions.
Using the PCap Touch Screen
The PCap touch screen responds to the lightest touches. Touching with a single finger
resembles the left mouse button. Two fingers are used to zoom IN (fingers brought
together) or zoom OUT (fingers pulled apart). Circular motion can be used to rotate an
element on the screen. This function must be supported by either the Operating System
or the application.
