Yesterday we saw an excellent condition Glowlight display unit at Target. We played with it. We were surprised our finger gestures stayed on the screen. So I wrote ABC on it, the glowing ABC stayed. We talked to the gentleman there, he didn't know it was a Glowlight unit; and the eink display units were largely ignored by shoppers. After 30 minutes, those glowing prints did not fade at all. I'll possibly check it later this week. Do you have any theory? Two screen layeres separated, maybe?
