MMS Electronics Ltd has available an exceptionally versatile line of DOG alphanumeric and graphic displays. (Display-On-Glass) The latest addition is the new 4×10 (line x char) EA DOGS104-A, high-contrast easy-to-read STN and FSTN display. Viewing area 33x12mm.
With double height character option the display transforms into a 2 x 10 or 3 x 10 display. The integrated SSD1803A controller offers 3/4-wire SPI and 2-wire I²C interfaces. Selection of 3 fonts: Cyrillic, English-Japanese and European. Supply voltage is +3.3V without the need for a negative voltage. A typical current of only 440µA (with LED backlight off) makes it ideal for battery powered, hand-held applications. Display and optional backlights are “mix & match”; There are 3 display matrix variants available, FSTN black/white positive – transflective and reflective and STN blue/white negative. There are 3 different LED backlight: amber, dual yellow-green/red and a trio green/red/white. The dual and trio colour backlights are ideal for applications where a normal (green) or warning (red) status indication is required.
In the same series there is the larger EA DOGM204. This display can be used as 2×20, 3×20 or 4×20 in double height character mode. Current requirement for the EA DOGM204 is only 250µA without use of the LED backlight. These displays could be battery powered making it ideal for handheld applications. The EA DOGM204 has an integrated SSD1803 controller with 4 bit, 8 bit, 4-wire SPI or 2-wire I²C interface. Display can be used in bottom or top view direction.
Selection of 3 different fonts: Cyrillic, English-Japanese and European. Displays with white background FSTN technology are readable without backlight. The display and backlights can be ordered separately to create 12 different combinations. 3 different LED backlights are available: white, amber and a dual green/red. The dual colour backlight is ideal for applications where a green (normal) or red (warning) status indication is required. The overall height is only 2mm and 5.8mm including an LED backlight. The displays can be soldered directly into the PCB without any further assembly.
A simulator tool and USB test board EA 9780-3USB is available to help with development. Without any programming the display is shown on the Windows™ desktop. The 9780-3USB board is powered via USB. Any text typed in the editor is displayed immediately on the display. The EA 9780-3USB test board can be used with all other alphanumeric and graphic DOG displays. In graphic mode bitmaps dragged into the simulator tool are also shown on a graphic display.
A memory stick EA USBSTICK-FONT has fonts available for the graphic displays. The font software can generate Cyrillic, Greek and Arabic fonts. Windows™ fonts are also easily imported. The preview function shows the size and style and when the EA 9780-3USB test board is connected characters are also shown on the display. The software generates headers to include in the source code.
Additionally there are Arduino shields available for most DOG displays.
