Contrast 1/2000: 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 is -40..+80°C.
Above all things with low temperatures the new OLED
displays do win every competition with standard
LCD modules!

OLED

Displays of the Superlative

Now the worldwide first OLED display with pins is available: EA OLEDL128-6GGA. Pins with pitch 2.54mm provide a much faster and easier demo design; just put the display directly on a breadboard.
More than this: even in mass production the pins facilitate all mounting needs automatically. There's no need for any mechanical construction: simply solder the display into a pcb or plug with sockets.

But there are more details that convince:

  • Top. -40..+80°C
  • extreme wide viewing angle of about 170°
  • contrast > 1:1000
  • display response time typ. 10µs

These displays come with an integrated controller and support SPI and I²C bus directly. The datasheet is linked here. More sizes like 102x64 pixel, 128x64 and a character type with 4x20 character will follow.

Contrast ratio 2000:1

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:

  • full contrast even down to -40°C
  • extrem fast response time: 10us (!)
  • no contrast adjustment necessary
  • no limitation in viewing angle

Continous operation without problems

Finally, the new OLED displays from the company ELECTRONIC ASSEMBLY can also be installed in industrial applications. Thanks to the new, patented OLED technology, the displays achieve a lifetime of 50,000 to 100,000 hours, depending on the color and ambient temperature.

Englisch, Japanse European, Cyrillic

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.

Character display 2x8..4x20

With it's well-known 4 bit and 8 bit parallel interface, the new OLED displays are similar to the HD44780 standard.

4-/8- Bit and SPI Interface

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.

In the graphics displays, we increasingly renounce on parallel connection and focus more and more on the serial interfaces SPI and I²C bus.

5V and 3.3V

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.

Our OLED graphic displays do mainly support 3.3V supply.
