7. Display Information
This section will outline some basic precautions
when using 4D Systems’ displays with the PICASO
OGM Module, along with a list of compatible 4D
Systems’ displays available.
7.1. Display Precautions
Below are some general guidelines and
precautions when using a 4D Systems display. The
PICASO OGM Module itself does not include a
display, however is compatible with 4D Systems 40
pin displays, 2.4”, 2.8”, 3.2” and 3.2” Wide.
• Avoid having to display the same image/object
on the screen for lengthy periods of time. This will
cause a burn-in which is a common problem with
all types of display technologies. Blank the screen
after a while or dim it very low by adjusting the
contrast. Better still; implement a screen saver
feature.
• Moisture and water can damage the display.
Moisture on the surface of a powered display will
cause the electrodes to corrode. Wipe off any
moisture gently or let the display dry before usage.
• Dirt from fingerprint oil and fat can easily stain
the surface of the display. Gently wipe off any
stains with a soft lint-free cloth.
• The performance of the display will degrade
under high temperature and humidity. Avoid such
conditions when storing.
• Do not tamper with the display flex cable that is
connected to the control board. This may affect
the connection between the display and the
driving circuitry and cause failure.
• Displays are susceptible to mechanical shock and
any force exerted on the module may result in
deformed zebra stripes, a cracked display cell and
broken backlight
• Always use the mounting holes on the module's
corner plates to mount the display.
