Digital paper display maker E Ink released its new ePaper color display product, the Kaleido 3, on Thursday, saying it offers color 30% richer than previous models. Digital paper only consumes power when making any changes to the content. These displays require extra light from the environment to show content, making them ideal for e-readers like Kindle. Based in Taiwan, E Ink earned NTD 19.7 billion ($680 million) in revenue last year, with NTD 5.2 billion yearly net profit, according to its annual report. [E Ink press release]
