Hitachi HD44780 LCD is a very common LCD standard for lots of hobbyist projects. (e.g. arduino projects).
You can also find it in use in many printers, and other products, due to its simple interface.
I wonder if it would be a good idea to somehow replace the LCD top with a standard eink LCD display.
Only problem I could see, is how to deal with ghosting in the eink screen. Also sometimes on power-off, you want to clear the screen, and sometimes you want to leave the content on. Not sure how to deal with that.
But that's why this idea is halfbaked anyway.-- mofosyne, May 03 2012 Hitachi HD44780 LCD controller http://en.wikipedia...4780_LCD_controller [mofosyne, May 03 2012] E-ink display pixels have a much much slower response time than LCD display pixels. So, e-ink displays are fine for static images, but not at all good for video.-- Vernon, May 03 2012 you'd need some intermediate circuitry, at which point you may as well get an e-ink display-controller that's deviceside pin/programming compatible with the aforesaid whatsis.-- FlyingToaster, May 03 2012 random, halfbakery
