Old transflective Palms were absolutely stunning displays in the bright sun too, this isn't a feat of engineering, it's just a feature of the display. The problem is stretching the screen larger, since the distance between the sidelight and the center of the screen increases significantly, so you end up with darker patches in the center or lighter/brighter edges of the screen. The alternative is to go with a thicker screen to allow the light to travel to the center, this works well for TVs but not nearly as well for a tablet sized device.

It might be bright and clear when it's sidelit though. I wrote and meant "BACKlit" -- better transflective displays are both transmissive and reflective -- something like partially silvered mirrors -- and work great with LED BACKlighting. >>and easily readable in direct full sunlight. > >Absolutely.

The alternative is BACKlighting, which scales very well. -- Best regards, John If the iPhone and iPad are really so impressive, then why do iFans keep making excuses for them?

The term "transflective" means *transmissive* + reflective <http://en.wikipedia.org/wiki/Transflective_liquid_crystal_display> which is backlit, not sidelit, otherwise the transmissive part would be pointless. Perhaps you are thinking of frontlit/sidelit *reflective* displays, which can indeed be poor, especially the earlier ones. -- Best regards, John If the iPhone and iPad are really so impressive, then why do iFans keep making excuses for them? |
