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 interfaces are used to program a
new Firmware/PmmC, Display Driver 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 is a USB to Serial-TTL UART
converter cable incorporating the Silabs CP2102 USB
to Serial UART bridge IC.
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.
The gen4 Interface boards (gen4-IB) ship with each
gen4 Display Module unless otherwise stated. Simply
connect the supplied 30 way FPC cable into the ZIF
connector on the gen4 Interface Board, and connect
the Programming Cable or Adaptor into the 5-way
header on the Interface Board. You are now ready to
program using a 4D Programming Cable. This can also
be used to interface to other devices such as a 4D
Arduino Adaptor Shield, breadboard etc.
