Scientific analysis finds iPhone LCD trumps Nexus One OLED

Most high-quality displays, including the iPhone, have at least 18-bit color, and emulate 24-bit color with dithering. But in his tests, Soneira found that the Nexus One screen uses only 16-bit color, which allows 32 possible intensity levels for red and blue, and 64 for green.

«This is common on cheap low-end devices, but it is unacceptable for an expensive high-performance ‘Super Phone’ that Google claims to to be,» he wrote. «All screen colors are derived from intensity mixtures of the RGP primaries — with so few levels to work with the colors are coarse and inaccurate, which produces quite noticeable false contouring in many images and photos.»

Soneira said the Nexus One display is best-described as «punchy,» and he feels the AM-OLED screen comes across as more of a prototype than a final product. With too much color saturation on photos and poor scaling of images, the hardware was also given «very poor» marks in terms of factory calibration and quality control. Without any color and grayscale calibration, Soneira said it appears the sub-assembly «was just slapped as-is into the phone, which is common in factories that are concerned with maximizing volume and minimizing production time and costs.»

Τα μειονεκτήματα του iPhone:

While the iPhone has a better display than the Nexus One, Soneira said it is far from perfect. Apple’s handset has contrast that is too low and weak color saturation. In fact, he said, the color gamut data shows the iPhone smaller and the Nexus One bigger than the standard. In that respect, the iPhone and Nexus One have taken the opposite approach.

Ο Dr. Raymond Soneira συμβουλεύει την Apple να αντισταθεί στην γοητεία της OLED για δύο ακόμη χρόνια και να προτιμήσει τις LCD. Προς το παρόν η Apple φαίνεται να κινείται προς αυτή ακριβώς την κατεύθυνση αν κρίνουμε από το iPad.
