the best/largest production transflective display i've seen was in asus eee note, which sadly wasn't directly sold in the west. https://www.laptopmag.com/uk/articles/asus-eee-note-ea800-note-taking-tablet-hands-on https://www.laptopmag.com/uk/articles/asus-eee-note-ea800-no... 8", 1024x768, 64 grayscale levels, wacom digitiser, sadly no backlight. the thing runs linux and is trivially easy to run custom code on. i still have a few units.
