Compact design and excellent legibility are the principal advantages of the new EA DOGM204-A family of alphanumeric displays from Electronic Assembly. Supertwist LCD technology produces a high-contrast display that is only 66 mm wide. The display offers a font size of 4.8 mm and supports four lines of text with up to 20 characters per line.
The display supports both SPI and I2C communication protocols, and the SSD1803A on-board controller almost completely eliminates the need for additional programming, reducing the workload for developers. Because users have the choice of three different character sets (European, English-Japanese and Cyrillic), equipment configured with these displays is suitable for most of the world’s major markets. Flexibility is another key feature of the EA DOGM204-A family. The display modules can be combined with three different backlighting colors.
The displays run on a single 3.3 V supply, supporting state-of-the-art design and reducing the cost of circuit infrastructure. Typical power consumption is only 250 µA, and the additional load for LED backlighting can be as low as 3 mA. There is no need for complex assembly during production because the displays can simply be soldered directly to the PCB, eliminating the need for mounting hardware. A thickness of only 2 mm supports ultra-slim design. Even with optional LED backlighting, the display is only 5.8 mm thick.
A USB test board which can be connected to a Windows PC is available for developers. Various sample applications and software can be downloaded free of charge.
