The new OLED technology provides because of its real black background and its active technology a contrast ratio of minimum 2000:1.
Operating temperature range -40..+80°C
More and more does the required temperature range for a typical LCD module exceed the possibilities. Above all things with low temperatures the new OLED displays do win every competition with standad LCD modules:
At last the new OLED display from ELECTRONIC ASSEMBLY are suitable for industrial applications. Thanks to the new, patent OLED technology the displays do reach a life time of 14khours, even at the maximum operating temperature of +80°C (half brightness).
The probable life time at room temperature is > 100,000 hours and more!
The new OLED displays do provide all important character sets as a standard already: English, Japanese, European and Cyrillic. Especially for the cold northern countries in Europe the new OLED displays are a perfect solution: full functionality in combination with cyrillic characters.
They also do provide a very fast display response time even at icy temperatures of -40°C. And the life time with such temperatures is no more a problem.
With it's well-known 4 bit and 8 bit parallel interface, the new OLED displays are similar to the HD44780 standard.

Besides the typical 4 and 8 bit interface for Z80 and 6800 systems all displays do provide the option for a SPI interface with MOSI, MISO, CS and CLK.
The new OLED are in both worlds: single supply operation with 5V and 3.3V without modification. The current consumption is, depending to the display size and content, between 15~50mA (typ.). The highest brightness can be reached with 5V operation.
