Qualcomm's Mirasol may have a reprieve

Qualcomm last year said it was not pursuing direct sales of it's colour e-ink solution Mirasol and would license the technology to partners.

Mirasol uses MEMS (micro-electromechanical systems) technology and is very low power, works in direct sunlight and low light conditions though it has been criticised for washed out colours.

At the SID Display Week event in Canada last week, Qualcomm seems to have reversed its decision and was very publicly displaying the latest version of the Mirasol technology and said it could appear in devices with small screens later this year (less than 1.5 inches - speculation is on some form of smart watch).

There was also a demonstration of a 5.1 inch screen with a resolution of 2560x1440 which equates to a pixels per inch (ppi) value of 577, while Samsung's Galaxy S4 has a resolution of 1920x1080 with a ppi of 440.

The Mirasol technology is really nice and it would be a shame if Qualcomm didn't maximise its market position and push the technology out soon.

Qualcomm drops Mirasol

Qualcomm has decided not to continue developing the Mirasol colour e-ink display solution, though it will license the technology to other parties. Mirasol uses a MEMS display that uses low power and can produce both static displays suitable for reading and if required video (though higher power is required in that mode as the display only uses power when the image changes). One major advantage of Mirasol is that it performs well in outdoor conditions under sunlight. Qualcomm originally purchased Iridigm Display in 2004 for $170m and subsequently purchased Pixtronix for $175m in January 2012 to strengthen the Mirasol technology. Qualcomm is still going to utilise Mirasol for niche applications but will adopt a licensing model for general use.
