Mirasol is a MEMS based reflective color display technology from Qualcomm. The company is already producing in small scale and are building a $1 billion factory in Taiwan. First panels are aimed towards e-readers (5.7") but the company has also recently unveiled a mobile phone prototype with a 4.1" color display.
While Mirasol displays offer video and color and are very power efficient, they also suffer from washed colors, and of course the screens aren't "bright" as they are reflective (although Mirasol thinks that edge lighting might be an option). Mirasol themselves admit that they cannot compete in the smart phone market yet - but interestingly we now hear that their CEO says that brighter displays are on the roadmap - and 'eventually' they could compete with OLED displays.
When showing the 4.1" concept, they said this is 3-4 years away, so this might give us an idea as to the time frame Qualcomm is talking about.
