I have a suggestion. Reflective LCD colour displays with no backlight.
You can get them in 8" tablet form as found in the TCL Nxtpaper S8 and in 32" monitor form as found in the Sun Vision Display.
- kurthr 4y agoIt's very hard to achieve even 2:1 real contrast ratios with color LCDs, because "white" light passing through color filters loses 80-90% of visible luminance (eg each green filter only covers ~30% of the area and passes <50% of lambertian daylight). This means the reflections off the front of the screen need to be less than 5-10% of ambient light. It's even worse for anything other than white or for specular light. Almost all LCDs are made trans-flective for this reason. If you went with B/W LCDs you can improve this by ~3x and might achieve 5:1 contrast with good antireflective surfaces. That's what you see in car LCDs.
