The EA DOG range from Electronic Assembly is claimed to be the world’s first display series which runs on 3.3V without auxiliary voltage.
The latest model in this extensive product family, which includes 1 x 8, 2 x 16, 3 x 16 character versions, is the first to offer a 4 x 20 character display. The EA DOGM204-A is extremely compact (66 x 40 mm) and features a standard 4.8 mm font size.
Three different technologies (STN and FSTN) are available as standard options. In contrast to conventional LCD modules, the display and backlighting are supplied separately. Backlighting is available in white, amber and green/red, and users have a choice of many combinations. This state-of-the-art LCD series is designed for hand-held devices with and without backlighting, and it offers a number of outstanding features:
* Super low profile, 2.0mm without backlighting or 5.8mm with LED backlighting.
* 4-bit, 8-bit, SPI (4-wire) and I²C (2-wire) interface at the SSD1803A controller.
* Typical current consumption only 250μA during normal operation (white LED backlighting 3 mA -80mA at 3.3V).
* Easy soldering for simple mounting.
* Operating temperature range -20 70°C.
In addition, a wide range of design variations can be supplied from quantities starting at 1; three different Cyrillic, English-Japanese and European characters sets are built in as a standard. Two mounting orientations are supported (6 o’clock and 12 o’clock). With monochrome backlighting, three separate LED paths which can be connected in series or parallel are provided for optimal matching between the display configuration and the system voltage. As a result, all backlighting units will run alternatively on 5V and some directly on 3.3V.
