ePaper Display - Electronic Label for Embedded Applications
The ELECTRONIC ASSEMBLY product range includes an intelligent electrophoretic active matrix display with excellent contrast and wide viewing angle. Electrophoretic displays are very popular because they are widely used in e-book readers. Extremely low power consumption and crystal-clear, high contrast image quality similar to printed paper are the most striking features of these displays. Readability is excellent even without lighting, making the displays ideal for applications such as electronic labelling.
The Electronic Assembly EA ELABEL20-A ePaper display has a diagonal size of 2" (approx. 5 cm). Built-in intelligence drastically reduces time to market. The display features a large number of graphic functions and 8 built-in fonts. Other fonts can be loaded as well. Positioning on all functions is pixel perfect. The units are capable of displaying any combination of text and graphics, and they also have a 2x and 4x character zoom function. The 64 Kbyte EEPROM memory mounted on the PCB has space among other things for up to 256 user-definable command sequences (macros) or an equal number of images. Three built-in interfaces (RS-232, SPI and I2C) are provided for controlling the displays.
The displays can be operated in portrait or landscape mode. The resolution is 172 x 72 or 72 x 172 pixels depending on the orientation. The text characters can be rotated 90° so that they are correctly displayed in either orientation.
Low power consumption and power-down mode make the embedded ePaper ideal for mobile and battery-operated applications. The operating voltage range is 3 V – 3.3 V. The display draws no more than 16 mA during screen update. Macros are still callable in power-down mode (0.2µA). The EA ELABEL20-A is supplied with a lithium battery which provides power for 1 -2 weeks of operation.
The EA 9780-3USB interface board with USB port facilitates connectivity to Windows PCs.
