Current engineering specs say 1500 nits brightness is required for 'good' readability in direct sunlight. CCFL's backlights delivering that brightness would pull amps, not mili-amps. LED backlights are better but current draw and heating are still problems. If you did somehow create a screen with 1500 nits brightness, it would be like looking into a car headlight. I can't find the specs, but I'm guessing the best glider displays are in the 500 - 1000 nit brightness range and pull around .8 amps. Far easier on the eyes and battery would be a high-contrast, high color saturation REFLECTIVE display like the Mirasol technology. |

I have no experience with competing displays so can't speak for them, but have flown ClearNav for three seasons and it is as "sunlight- readable" as it needs to be. No problem viewing it on bright days while wearing sunglasses. My problem is fine print in any light condition so I keep glasses handy for that, but if you set it up correctly before flight there is little need to read fine print. No need to flip through multiple pages, either. Control inputs are through a simple controller that you don't have to look at to use - particularly if it's mounted on the stick. Power management is built into the system so that isn't a problem. |

But I have found that display brightness in an aircraft quality display has little to do with sunlight readability. The key factors are the coatings and the contrast ratio. The Ultimate Le has two specialized coatings and an extremely high contrast ratio, it is as readable in the sun at the low backlight settings as in the high backlight. The sun has no noticable effect on the Ultimate Le display. The Ultimate Le with LED backlight has no heat problems. In fact the first Ultimates with a CFFL backlight got warm but did not have any issues. Displays with low contrast ratios need unusaully high backlight to be seen. This is typical of most low cost low qualtiy displays. The Ultimate Le at full backlight has 1400 nits and draws about .7 to .8 Amps. At lower backlight settings of .3 to .4 amps the display is very sunlight viewable with vibrant colors. All the above information comes from testing in direct sunlight from a varitey of angles and first hand experience in flight. Richard www.craggyaero.com |

OK, is it possible to get one ? Hacked to run Android ? |

I don't know about getting one. However, I understand this technology
is great for an Ebook with basically static page displays, but screen updates are very slow. It wouldn't work well with continuously updated moving map displays.

I suspect you may be confusing E-Ink with Qualcom's Mirasol display.
E-Ink is slow but Mirasol is easily fast enough to display video in vibrant color. As for getting one, there are grey market sources if you want it right now but I expect to see a device like it on sale world-wide soon. Most e-readers have proven vulnerable to rooting so Android is potentially doable. I suspect a Windows 8 tablet with the technology will be available in 2012.

Perhaps this device has potential -

Another Mirasol spotting, unclear if available in the west:
