Hi Can anyone reccomend a graphic display that is readable in bright light conditions - preferably full sun. I am currently using Displaytech 128x64 pixel monochrome display and the GLCD library. Everything is really good except I cant read it outdoors. I have destroyed one display already by increasing current in backlight to the point where the LEDS failed. I have heard OLED displays are better, but because they are usually colour they are very slow, I need to refresh parts of the display 3 or 4 times per second. Grateful for any help
For monochrome OLEDs, the Arduino does not need to transfer too much data. So 3 to 15 FPS should be possible with U8glib (depends on the display content): http://www.newhavendisplay.com/nhd2712864ucy3-p-3621.html
EA offers displays for different environment conditions. http://www.lcd-module.com/eng/pdf/grafik/dogm128e.pdf For bright light conditions you probabaly want a display which is readable without backlight: DOGM128L or DOGM128W. Backlight LED is sold as an option for the DOGM128, it can be replaced if damaged ;) i think the trick is, not to use the backlight LED at all, but let the sun do the lightning work for you.
Both displays are supported by U8glib (http://code.google.com/p/u8glib/)
How about those e-ink displays?
where the LEDS failed.
Should have a resistor there.
