While Pixel Qi on their website explicitly states that their displays are not based on eInk technology and that they are not affiliated with eInk Corporation this piece of news is highly related to eInk, because potentially we may have a eInk competitor here.
It is a display which according to Pixel Qi is extremely cheap to build from standard LCD display components and in fact it is for the most part an LCD display. With one exception – it can be switched to reflective mode. In this mode it consumes much less power than ordinary LCD display would and becomes monochrome but it can potentially display 3x as many pixels.
According to Pixel Qi consumers will see these displays in notebooks and netbooks by the end of 2009 and in “other devices” sometime in 2010. It looks like it’s easy to integrate this technology into existing designs since according to nerdword, Pixel Qi engineers rigged couple of retail-purchased laptops with their new display with seemingly little effort.
While this technology is mainly geared towards netbooks, notebooks and cellphones to make them usable in the sunlight (another interesting piece of news being Pixel Qi planning to supply displays for $75 laptops), it’s quite possible that much cheaper products price along with acceptable power consumption (though still much higher than eInk which is based on electrophoretic technology) and ongoing developments in battery technology may produce eBook reader that will run for several days on one charge, be usable in sunlight and cost less than Amazon Kindle.
