microOLED GOLDELOX DISPLAY
to the GOLDELOX on your application board. This
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 SDHC 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. OLED Screen Precautions
• Avoid having a White Background. The more
pixels that are lit up, the more the display module
will consume current. A full white screen will have
the highest power consumption.
• Avoid displaying objects or text on White
Backgrounds. This will cause a smearing effect
which is inherent to all PMOLED displays. Instead
try a shaded mixed colour as the background or
better still a black background. Ideally have mixed
coloured objects/text/icons on a black
background.
• 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.
• The display can be easily scratched. The soft
polarisation film on the glass surface may be
damaged if rubbed by hard objects. Handle with
care to avoid scratching the display.
• 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.
• Displays are susceptible to mechanical shock and
any force exerted on the module may result in
deformed zebra strips and cracks.
• Always use the mounting holes on the module's
printed circuit board to mount the display.
