Any suggestions for a low power graphic serial LCD?

LarryG

I have a good portion of my Propeller bike computer working on the breadboard. My focus is now turning to the display selection. . I currently have a 4D Systems uOLED, but it consumes around 40mA. Since I am running on battery, I would like to find something that consumes 20mA or less if possible. I searched the usual: DigiKey, Mouser, etc. with no luck.

Looking for something that:

-Has high contrast ratio for outdoor use
-Can control with serial commands from the Prop. Like the 4D display, I can issue a "circle" command and it draws a circle.
-Graphical
-Monochrome is OK
-Ideal size is 38mm x 38mm, but somewhat flexible on that
-Cost less than $50US

Any suggestions? Or am I looking for something that does not exist?

Thanks

What about this guy?

Uses SPI, but that's easy to do with the prop. You will probably have to write code to do a circle, but that's been done before...I'm sure you can find code and adapt it. Claims 250uA for the display, and 5-80mA for the backlight.

I must say that I do like those DOGM displays... There have been posts about them before, but they were just in Germany. Nice to see them for sale in the USA.

Thanks Jon and Ray. The DOG looks like a great alternative, and for only $12 it is worth it to get a couple to try out. It claims 250uA, which blows my mind. I could get about 24hrs of run time per charge with that in my project. It is not clear to me how to do circles and other graphic stuff. but once I get my hands on it I can see if that will be practical for someone with my limited experience.

Thanks guys.

I have been using these 128x64 graphic displays using a clock and data line from the Prop. Although they are not advertised as being serial I found that the controller accepts clock and data. You can follow the thread here http://forums.parallax.com/showthread.php?p=855774
