Just ran a calibration check on a HTC desire AMOLED smartphone display. The greyscale tracking is nothing short of superb. Gamma is also first rate, with a steady 2.3 throughout 0ire to 100ire. The performance betters my Sony grade 1 broadcast CRT monitor.
Colour quality is good. Luminance being good. However, the gamut is the only thing that is out, as it is very wide (Highly saturated).
I managed to get the colour temp to track 65k by using an app called Screen adjuster', adjusts the individual RGB levels, also adjusts screen contrast level.
The image from these AMOLED screens are fantastic. However, there is a slight colour distortion when viewed at wider angles.
Anyone else measured the performance of their smartphones, just wondered how the Apple Retina display would fair?
