microLCD GOLDELOX DISPLAY
offers enormous advantage to the designer in
development time and cost saving and takes away
all of the burden of low level design.

SD/SDHC Memory Cards 6.3.
The module supports micro-SD memory cards via
the on-board micro-SD connector. The memory
card is used for all
multimedia file retrieval
such as images,
animations and movie
clips. The memory card
can also be used as
general purpose storage
for data logging applications. Support is available
for off the shelf micro-SD (up to 2GB) and high
capacity HC memory cards (4GB and above).
Note: A microSD card capable of SPI is a
requirement for all 4D Systems’ display modules
powered by Goldelox, Picaso or Diablo16
Processors. If a non-SPI compatible card is used, it
will simply fail to mount, or may cause
intermittent issues resulting in lock ups and
crashing of the application. Please refer to the 4D
Systems website for microSD cards offered by 4D
Systems.
7. Display Precautions
• 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
printed circuit board to mount the display.
