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:
1 Unpacking the touchscreen
2 Disassembling the monitor
3 Determining touchscreen fit
4 Mounting the touchscreen
5 Installing the controller
6 Power
7 Reassembling 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.
