Display/Module Precautions
Avoid having to display the same image/object
on the screen for lengthy periods of time. This
can 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
should not cause any problems, however if water
is to enter the display either from the front or
from the rear, or come in contact with the PCB,
damage will certainly occur. Wipe off any
moisture gently or let the display dry before
usage. If using this display module in an
environment where it can get wet, ensure an
appropriate enclosure is used.
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 where
possible.
Display modules have a finite life, which is
typically dictated by the display itself, more
specifically the backlight. The backlight contains
LED’s, which fade over time. In the
is a figure for the typical life of the
display, and the criteria are listed.
Resistive Touch model features a touch sensitive
film over the display which is sensitive to
pressure. Take note when mounting the display
module in an enclosure that pressure is not
applied to the surface of the display by the
enclosure, or false touches will occur, or the
touch will simply not function at all.

Hardware Tools
The following hardware tools are required for full
control of the gen4 Integrated Display Modules.
7.1.
4D Programming Cable/Adaptor
The 4D Programming Cable and uUSB-PA5
Programming Adaptor are essential hardware tools to
program, customise and test the Picaso Processor.
Either the 4D Programming Cable or the uUSB-PA5
Programming Adaptor can be used for the gen4
series of Display Modules.
The 4D programming interfaces are used to program
a new Firmware/PmmC and for downloading
compiled 4DGL code into the processor. They even
serve as an interface for communicating serial data to
the PC.
The 4D Programming Cable and uUSB-PA5
Programming Adaptor are available from 4D Systems,
Using a non-4D programming interface could damage
your processor, and void your Warranty.
Please note, in conjunction with a Programming
Cable or a Programming Adaptor, the gen4 series of
Display Modules requires a simple interface board
(gen4-IB), as there is no 5 way male header on gen4
modules like other 4D Systems modules.
