looking for sunlight-readable graphic display

Hello, I am looking for a sunlight-readable graphic display, about 3" x 2", that will be used in a battery-powered device outdoors anywhere in North America. I really like the look of e-paper but am concerned about the low temperature performance since the lowest rated temp that I have seen is -25°C (-13°F). I am concerned about the power consumption of OLED. Any recommendations on a readily-available display? Also I would like to test the display without having to develop drive circuitry and code. What demo kits are available that will display a changing image? Thanks for any ideas, Ron
