Electronic Assembly has introduced a range of OLEDs for use in industrial applications. The nine models feature an extremely high contrast ratio of 2000:1, achieved by using a genuinely black background and active display technology. A new, patented system eliminates the relatively short service life of previous OLED displays. The displays can be operated for 100,000 hours and more at room temperature. Even when used at maximum operating temperature (80°C), they retain 50 per cent or their original brightness after 14,000 hours.
The OLED displays also provide full contrast at temperatures down to -40°C. No contrast adjustment is required for this. Their response time of 10 microseconds gives the displays an extremely fast response time as well, whether they are used at high or low temperatures. In addition, information shown on the OLED displays is easy to read, no matter what the viewing angle.
All major character sets – English, European, Japanese, and Cyrillic – are integrated in the alphanumeric displays and do not need to be created by the controller. Connection to the outside world is similar to the established HD44780 standard via 4- and 8-bit interfaces. Power is provided by a 3.3 or 5V single supply, whereby the brightest brightness is achieved with the 5V supply. Consumption ranges between 15 and 50 milliamperes, depending on the size of the display and the display content.
Electronic Assembly offers nine different organic displays. Colours include yellow or white, and the display area encompasses two rows with up to eight characters each or four rows with up to 20 characters each, depending on the model.
