“Three letters, CBD, CBD” Said Anssi Vanjoki when Nokia introduced the technology at Nokia World 2010. He explained that CBD, which stands for Clear Black Display, is “a premium touchscreen that provides higher contrast viewing experience than anything before.”
But lets remember that Nokia’s phones with CBD are also AMOLED, so technically, the E7 has a CBD AMOLED display. It is really nice to see that Nokia is up there competing with Samsung in display technology, but what is the difference between Samsung’s SuperAMOLED and Nokia’s CBD AMOLED displays? Here is the E7 vs. the Galaxy S. They have both a 4″ display, but they have different technologies over the standard AMOLED.
The E7 product manager explained that CBD is a filter that blocks light from entering the screen, so annoying reflections won’t show in the screen hindering the user’s view. The result? According to Nokia, you should be able to see your CDB AMOLED display comfortably outdoors.
So which one is better? I believe that this is a very subjective opinion. Some people will think that SuperAMOLED produces better colors, and others will think the E7’s CBD AMOLED is superior. The truth is that the Galaxy S display might be better than the E7’s, but that will be because of the resolution. The Galaxy S has a 480 x 800 display, while the E7 has the typical 360 x 640 nHD display. Which screen do you think is better?
