Qualcomm revealed in their latest financial conference call that it scrapped Mirasol production plans. The company will no longer attempt to produce these panels, but will try to license the technology for other companies to produce. They will also limit their direct commercialization to "certain" devices - I'm not totally sure what this means.
That's sad news, as the technology is very interesting, and the prototypes shown at SID 2012 were very impressive (above you can see 1.5" 288x192 30Hz Mirasol display panel prototypes). The company did produce some 5.7" color panels (and three e-readers are shipping using those panels) Apparently Qualcomm didn't manage to overcome the low production yields. Mirasol production was planned since back in January 2011, but were later delayed several times. The original plan was to invest $1 billion in a Taiwan-based factory.
