Most of high end smartphones use Amoled screen, a display technology for use in mobile devices. However Amoled screen has a performance problems when viewed outdoor under bright sun thus in fact, the first mobile phone that uses AMOLED screen is almost unusable outdoors.
As the development of Amoled technology is growing, it's weakness was eventually repaired. We can see when the Super Amoled screen Samsung was introduced with outdoors visibility significantly better, and today Amoled display exceeds the LCD when viewed under sunlight.
The Amoled screen technology also adopted in Nokia in their high end smartphones. Interestingly, although Samsung and Nokia both use the same screen technology, it does not mean the ability of the screen is the same.
DisplayMate had them compared on the visibility test. The results indicated that the Amoled screen on Nokia Lumia 900 with Clear Black Display technology turns out to have excellent performance under bright sunlight when compared with Galaxy S and iPhone 4.
The results of the visibility test of Lumia 900 has highest points, 90, beat the Super Amoled Samsung Galaxy S with 80 points, and the Apple iPhone 4 sitting in third position with 77 points.
The question is, why DisplayMate chose to compare the Nokia Lumia 900 with two smartphones aged 2 years older, like the Galaxy S and iPhone 4. Although there are a few new phones which make more sense to be compared with Nokia Lumia 900, like HTC One X and Galaxy S III for example.
