Nokia has always touted its ClearBlack display technology in its Lumia Windows Phone devices. The CBD technology on a AMOLED display enables high readability even when in the outdoor scenarios. In a study by DisplayMate on comparingÂ Â visual performance and viewability of Tablet and Smartphone displays in high Ambient Lighting, Nokia Lumia 900′s CBD display won the best performing display title.
The Winner:Â The DisplayMateÂ Contrast Rating for High Ambient LightÂ for the displays ranges from a low of 15 (HTC Desire) to a high of 90 (Nokia Lumia 900). From both the Lab Measurements and the Screen Shot Viewing Tests (below) the top performing device for display viewability under Bright Ambient Lighting is theÂ Nokia Lumia 900. This results from a combination of its high screen Brightness and low screen Reflectance, which Nokia callsÂ ClearBlackÂ technology. The Samsung Galaxy S and Apple iPhone 4 are tied for second place.
