< the artificial light will be swamped by daylight. > It's [to me] surprising how little light is needed for night-time eyes to see [cones versus rods and open iris] and the vast difference from the amount of lights in bright daylight. hyperphysics.phy-astr.gsu.edu

Quite right, any electric lighting of the mirasol screen must be trivial compared with sunshine-based outdoor viewing.

PS:

1/ I happened to be [play] fighting a cat behind a couch [I am not sure the cat knew it was play as they go quite crazed]. It's eyes rapidly went from narrow slits to wide open ovals as it evaluated whether to attack fingers poking around a corner. Cats are very good at both dark and bright sunshine eye function.

I have "fought" a lot of cats but don't recall such a rapid and extreme change in iris. The cat won the psychological battle - I surrendered. The cat was okay with surrender. Mirasol is not as good as cat's eyes, but it's a good start.

2/ I have not read anything about rods and cones since 4th form [some half century ago]. Cyberspace is amazing that the information is there [url above] and what was a big effort to be told by a teacher is now flashed right there in Cyberspace in an instant in full glorious detail. Cancel school! More play, less school.

3/ This data is being moved via a Telecom usb Sierra 308 HSPA 'stick' which I have just got going in my cheap little Samsung EeePC replacement. I have just got the stick going after using a nearby wifi hot-spot by Zenbu. I have never used a Qualcomm asic in a Sierra usb thingy so this is quite a big deal. Not that it's new. Now it's blase, prosaic and a bit of a yawn [to most people]. I have had the stick for several months but have not got around to getting it going [with wifi it wasn't really necessary but it's quite quick compared with my weak 1 bar wifi signal]. Go Qualcomm. In 1998, it was great to stand outside Qualcomm's Design Centre building and use a QCP820 to phone home. Now I have a Sierra 308 zooming packets flat out through Cyberspace. It's quite impressive.

The screen is reflective so the artificial light will be swamped by daylight.

The frontlight would be off in outdoors situations so this wouldnt be a factor.

It might be that the frontlight creates a gap between the touchscreen and the Mirasol display itself causing reflections that dampen performance. Complete speculation on my part, but this is what caused subpar outdoor performance in first generation OLED's. It was only when Samsung integrated the touchscreen and the OLED that the display could even match LCD outdoor performance.

The reflective light has to get into and out of the MEMS pixels. The lighting channels have to be located between the pixels and the reflective lighting source. The bigger the channels (on a microscopic scale) the bigger the impact. Something must account for the differences in quality between previously demoed Mirasol product and this launched product. I to expect the front light to be off with outside viewing.
