provided by the chip to interface directly to the

display. Simply choose your display and interface it 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.

5.3. SD/SDHC Memory Cards

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 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.

6. 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.
