I have a Galaxy 5S with an AMOLED screen which is supposed to be great in direct sunlight, but it is not nearly as visible in direct sunlight as my sold Streak was. Are the LCD screens any better? Are the newer AMOLD screens better than the earlier generation AMOLD screens?

Yes, newer AMOLED screens are definitely brighter. They get brighter and brighter every year, and they are certainly brighter than LCD screens.

Screen Brightness has little to do with sunlight readability. A very bright backlight will make a Poor screen sort of readable in the sun.

True Sunlight readable displays have a very high contrast ratio, and two specialized coatings anti-glare and anti-reflective. If a display has these features brightness is not a factor.

Uh? Suppose that the light coming from the screen is at level 1000 in the white areas and 1 in the black areas. Good contrast in a dark room. Now add 10,000 units of sunshine. If the screen reflects even only 10% of that, the "black" areas are now 1001 and the white areas 2000 - contrast gone to hell. Brightness matters.

That's why I'm using a device with an e-ink purely-reflective display: in that case, more incident light does not change the contrast at all.

moshe,

I have been building flight computers since 2008. The Craggy Aero Ultimate, Ultimate Le, Ultimate Le 57. My first sale was to a customer that saw the display in my glider, the display was in the shade no direct sunlight, colors looked great. Then he said turn the glider so the sun is on the screen. I turned the glider and there was a shade line from the panel cover on the panel but it was not seen on the display. Then I turned down the backlight little change, shade line still not visible on the display. A true sunlight readable display. It has the following specifications extremely high contrast ratio, two specialized coatings and an adjustable backlight. Brightness matters but as not much as you think, the glare and the reflection is the biggest problem.
