First Mirasol eReader Goes On Sale

It is almost two years to the day when Qualcomm first demoed its low power colour screen technology called Mirasol, and only now has it revealed the first device to feature it.

Mirasol is an ultra low power colour screen technology which, like e-ink, consumes no power when static and can be easily read in direct sunlight. Unlike e-ink though, it also uses a fraction (around 30 per cent) of the power of today's LCDs when showing dynamic content.

Qualcomm’s technology will be seen first in a 5.7in ereader from South Korean manufacturer Kyobo (not to be confused with Kobo) which has gone on sale in the company’s home territory today with a price of around £200.

Mirasol, which is Qualcomm’s entrance to the display industry, incurred an operating loss of more than $300 million for its fiscal year 2012 as it ramps up production.

The Kyobo eReader’s 5.7in touchscreen has a resolution of 1024 x 768 (223ppi) and is powered by a single-core 1GHz Snapdragon processor. It will be running Android 2.3.

The major benefit of the Mirasol display is power efficiency with the ereader promising “weeks of reading” on a single charge but that comes with a rather large caveat – that you only read for 30 minutes a day and set the brightness at 25 per cent.

Mirasol screens certainly offer some of the best features of e-ink and LCD in one, but whether the technology will gain widespread adoption is as yet unclear. We wait to hear whether the Kyobo ereader will go on sale outside of South Korea but for now, let us know in the comments if you think that this technology is the future.

Something does not add up here. First you say the display uses "consumes no power when static and can be easily read in direct sunlight." Then you go on to reference setting "the brightness at 25 per cent" as a power efficiency measure.

So if it consumes "no power", how do you vary the brightness, and how much of the "no power" consumed can be saved at a brightness setting of 25%?

from different news stories, apparently the Mirasol screen itself is similar in technology to E-Ink, in that power is only required to *change* the image, therefore requiring no power when it's static.

The difference, however, is that this particular device has a ring of side mounted LEDs so that when you are in the dark you can turn on a built-in front-lit reading light, so that is probably where the brightness part comes from...
