Here’s some interesting hardware for you: Sharp came out with a very cool series of LCD displays, gong by the name Sharp Memory LCD. Not only are these displays very low power – on the order of about 5 microAmps to keep the display alive – but some of the smaller displays are reflective, making them eminently readable even in daylight. [Mike] decided he’d take a look at these displays and liked what he found.
While these displays are still pretty new, there are a few breakout boards available to make them accessible to desktop tinkerers. The folks at MakerDyne have a breakout board available and there’s one by kuzyatech over on Tindie.
While these displays are readable in daylight and are extremely low power, don’t expect to display LCD video on them anytime soon. The refresh rate is still fairly slow, but you might be able to get away with simple animations with interlacing and so forth. Still, outside of eink, you’re not going to find a better display in terms of power consumption and daylight readability.
