The PixelQi display spun from the OLPC project was really good and clearly affordable, considering the original target market. Granted, E-ink is superior in many aspects, but I'd settle for a sunlight readable, low power monochrome LCD display. As an added benefit it updates much faster than E-ink.

> The PixelQi display spun from the OLPC project was really good and clearly affordable, I am curious if you work in the display industry. Do you know what the pricing for PQi displays actually was? Did you actually use a PixelQi display on a daily basis yourself? To be clear, I'm not attempting to be negative, but I actually work in the display industry and found the PixelQi display on the OLPC-XO-1 to be unusable. My perception of the display was one with very low quality color with backlight; and terrible viewing angle and unreadable contrast levels in bright sunlight. It also had low resolution. The XO-1 display I had access to had lots of pixel defects. If I am not mistaken (as I do not know actual pricing that Quanta got for the PixelQi displays) they were more expensive than LCDs and required additional parts that made managing their supply chain overall difficult. Most experts in my industry that I talked to expressed the opinion that it was a reality-distortion field type charismatic executive who managed to convince people at OLPC to try that idea. It was funded by UN and money from developing countries budgets who were excited by the promise of being able to educate their masses. Sadly it looks as if those countries were taken for a ride, rather than benefiting from a genuinely merit based idea. So I am very interested to hear what details you will share to back up the "really good" and "clearly affordable" parts of your claim. If your claim is true then it would suggest that my whole industry ought to abandon our current design and architectural roadmaps and switch to Jepsen's design! :-D I say that in a humourous context because last I heard in 2019 Jepsen abandoned badmouthing the entire display industry and switched to talking about telepathy and VR.
