This LCD looks like just the thing I am in need of for my new project. Just one question for now, does anyone know how well it works under sunlight?
This type of reflective LCD should do well in sunlight (though I do not have first hand experience with it). Since it does not have a backlight, it will probably not do well in low light situations. You should also note that it does not have a controller, so you will have to drive the LCD yourself.
I will try it in daylight and let you know, but it should do well.
Like muntron said it doesn’t have any kind of light so you need to have a fair amount of light to see it (like a LCD calculator).
There is no controller so you need to drive each segment, you’ll need alot of I/O pins for it. It is much like a multiplexed LED display, only you need to reverse the current every other time (LCDs don’t like DC).
Also it’s best if you can adjust the voltage going to the display to change the contrast. It works best from about 3.0 to 4.0 volts. Below 3.0 and it gets dim, above 4.0 and you start seeing the off segments.
I have interfaced this LCD so let me know if you need some help.
[edit] Here is a good app note about driving bare LCDs http://ww1.microchip.com/downloads/en/A … 00563c.pdf
