Yesterday, reviews website Digital Versus updated its review of Apple's iPhone 4S.
In-line with the multitude of other reviews roaming free across the Internet, the review's findings were that many areas of the hardware and, with thanks to iOS 5, the software had been improved upon or at the very least matched the original specification of the iPhone 4. That is, however, until the team updated the review following results from lab testing on the iPhone 4S IPS 'Retina' display panel.
Curious that the display panel hardware seemingly hadn't changed a over year later, since the release of the iPhone 4, the team began new tests upon on the 4S. The findings were, in comparison to the original 4 model, that screen contrast had fallen from 880:1 to 850:1, a drop of 30 units. The findings also discovered a reduction in colour accuracy as the DeltaE value, which measures how far from the original source image the reproduced colour is, rose from 5.8 to 6.2.
These differences are relatively minor, though perhaps enough to indicate that the iPhone 4S panels are not identical to those found in the original iPhone 4. The figures become somewhat more important when we consider that Apple focuses on the colour reproduction qualities of IPS panels, as opposed to the strong, saturated colours of recent OLED displays as one of its devices' selling points.
With some competing phones already boasting superior colour accuracy, such as the HTC Titan, along with the increasingly impressive, infinite contrast - albeit not very colour accurate - OLED displays, now is a time when Apple should perhaps be focusing on improving or at least maintaining the quality of its displays.
