Touchscreens

There are two types of touchscreens for the NCR 7613:

•Projected Capacitive (PCap) Touchscreen

•Resistive Touchscreen

Projected Capacitive Touchscreen

PCap touchscreens have all the benefits of normal capacitive touchscreens 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

In addition, the technology of PCap touchscreens is characterized by significantly higher robustness and stability than common capacitive touchscreens because the active touch surface is located on the back side of the touchscreen. 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 touchscreen the NCR 7613 can be used in public or severe environmental conditions.

Using the PCap Touchscreen

The PCap touchscreen 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.

Resistive Touchscreen

The resistive TFT touchscreen is constructed of a hard-coated polyester top sheet that is overlaid on a conductive-coated glass layer. Voltage is applied to the top sheet. As a user touches the screen, the top sheet compresses and comes into contact with the glass layer, causing current to flow to the four corners in proportion to the distance from the edge. This controller then calculates the position of the finger, based on the current flow. Because the controller derives both the "X" and "Y" touch coordinates from the stable glass layer, the accuracy and operation of the touchscreen is unaffected by any damage that may have occurred to the top sheet.

Using the Resistive Touchscreen

The resistive touchscreen functions as traditional single touchscreens.

Touchscreen Cleaning Procedures

1.Using a soft cloth dampened with isopropyl alcohol or a mild non-abrasive soap & water solution, gently wipe the touchscreen clean.

2.Wipe the screen and edges dry.

3.Make sure the glass and screen edges dry completely before using the unit.

4.Do not use sharp objects to clean around the edges of the touchscreen
