EA DOG displays

EA DOG monochrome Chip-On-Glass Displays (COG) are low cost, low current and highly reliable displays that are designed by Display Visions. With the COG displays the driver is mounted directly on the glass resulting in a thin display with very reliable connections sealed from the environment. For easy mounting pins are fixed to the edge of the glass with conductive glue offering a very stable connection to solder directly into the PCB or a 2.54mm pitch connector. The EA DOG series displays and backlights are specially developed for +3.3V supply voltage. (Note: Supply voltage for the Alphanumeric DOGM081/162/163 displays is +3.3V and +5V). Unlike other displays, this series allows you to select the display technology and the LED backlight colour. Simply clip the display glass and the LED backlight together and create many colour combinations from standard parts. Or create a designer special for you products from an MOQ of one. The glass technology is available in STN yellow/green, STN reflective, STN negative blue, FSTN blue, FSTN positive and FSTN negative with a choice of different backlights in Green, Red, Amber, Blue, White and dual Green/Red, triple Green/Red/White or full colour RGB backlights.

Features

Very fast response time (Typical 10uSec).
No contrast adjustment required.
Interface option 4/8 bit, SPI and I2C (Check datasheet).
Thin display: only 2.0 mm without backlight or 5.8 mm including the LED backlight.
Low power (Typical. 250 micro Amp) ideal for battery powered applications such as pagers or key fobs.
LED backlight in many colours
Character size 12.0 mm, 5.6 mm, 3.6 mm and 2.6mm for Alphanumeric displays
Optional analogue 4 wire resistive and PCAP touch-screens.

How to order? First select the display glass, then the LED backlight colour and a touch-screen if required. See display datasheet for details or install the display simulator, see link and details below.

Download DOG display simulator software

Download the free of charge DOG-Simulator and experiment with all combinations of display technology and LED backlight colours. Show the DOG displays on your desktop without any programming or order the EA 9780-4USB test board to power your display. Fit the display into the EA 9780-4USB board, connect power to the USB. The type text or drag and drop a monochrome picture into the DOG-simulator software and the text or picture will be immediately displayed on the DOG display. Demonstrate the display to your team without writing any code. The EA 9780-4USB powers all available alphanumeric and graphic DOG displays.
