Testers claim the iPhone LCD has advantages over the Nexus One AMOLED

Despite the general belief suggesting the AMOLED display of the Nexus One is superior to LCDs used by most smartphones, like the iPhone and others, recent tests performed by the testing equipment company DisplayMate have imposed somehow different conclusions. The tests performed on the Nexus One and the iPhone have covered a series of observations including colour depth, brightness, contrast, image quality and other characteristics, according to Dr, Raymond Soneira, president of DisplayMate.
The 800×480 OLED display of the Nexus One provides a higher pixel density and resolution than the 480×320 LCD on the iPhone. However, HTC uses a PenTile pixel arrangement that is considered to lack the sharpness of an LCD equivalent with an 800×480 resolution.
A “shocking” element in Displaymate’s opinion is related to the limited 16-bit colour for the Nexus One display, which allows only 64 levels of intensity for green and 32 levels for red or blue. Testers consider this to be found on cheap low-end devices but in any case not permitted for an expensive high-end phone like Google’s device. The limited 16-bit colour becomes obvious when visualizing the intensity scale ramps, where the Nexus One displays blatant steps and also green-magenta tingeing on white, while the iPhone displays smooth ramps, free from artifacts.
Menu graphics, text and icons generated by the Android OS are very sharp and well done, with an excellent rendering, but when it comes to the really important images, photographs, pictures from external sources, no matter if taken with digital cameras or from web sources, all these are rendered inaccurately and poorly, with over-saturated colours, calibration errors, image noise derived from excessive edge and sharpness processing. They show either bad colour and gray-scale accuracy or large colour and gray-scale tracking errors, says Raymond Soneira.
The peak white brightness was found to be poorer on the Nexus One, although it has impressive contrast ratio and black levels. Integration of dynamic colour and dynamic contrast technology for automatic enhancing of the images is criticized by the testing company, which considers this conversion more suitable as an option.
DisplayMate will continue to issue reports on additional tests and will eventually release a detailed report comparing the displays on each device.

I personally disagree. I have both, and gave away my iPhone. The nexus one screen is gorgeous compared to the iPhone, I mean the iPhone looked like a 3rd world knock off in comparison. I really don’t care about technical differences that are invisibleto the naked eye. The nexus one screen is bright vibrant and crystal clear while the iPhone seems shoddy, like last years tube TV.
By the way when I showed my nexus one to several office mates with iPhones they all oohed and ahhed. That seems to say something in my book.
Check out xda-developers, they proved the results are wrong, DisplayMate is wrong.
It is an unfair compassion. They should have used half Nexus one display, because the resolution is higher. just compare it with two real pictures and you’ll see the difference. If you do the same test with an old TV and LCD, you will see according to this test, old TVs will win.
