Summary of Installation Steps

This section describes integration of an LCD. There are two types of integration: desktop LCD or LCD component. If integrating a touchscreen on an LCD desktop, then bezel redesign may be required. See “Design Considerations for CRTs and LCDs” on page 2-6, for bezel design recommendations.

A typical LCD installation process consists of the following steps:

1Unpacking the touchscreen

2Disassembling the monitor

3Determining touchscreen fit

4Mounting the touchscreen

5Installing the controller

6Power

7Reassembling the monitor

Unpacking the Touchscreen

Handle the touchscreen with care. Note the transducers in the corners are especially fragile. Although the transducers may be recessed from the edge of the glass, do not handle them unless inspection is necessary. Note the location of the transducers and wiring. If any of the wires are accidentally broken during handling or installation, or if a wire is disconnected, the touchscreen will not operate. Avoid excessive handling and stress on the touchscreen cable. Elo touchscreens are pre-cleaned, so avoid getting fingerprints on the touchscreen by wearing gloves.

Testing the Monitor

The display must be in good working order before beginning the installation of the touchscreen. Inspect the LCD monitor for cosmetic flaws or damage. With a new display, it is suggested that you test the display by running it overnight.

Check for acceptable color, brightness, contrast, picture stability, and other QC tests.
