A good scientific review by DisplayMate. Link is here. http://www.displaymate.com/Smartphone_ShootOut_2.htmDisplay Partial summary: The iPhone 5 Display: Its still a Retina Display with 326 Pixels Per Inch PPI and with a Resolution of 1136x640 pixels. We were hoping for 1280x720, which is Standard High Definition HD, but presumably that will be for the iPhone 6. Thats not a disappointment, just a wish list Based on our extensive Lab measurements the iPhone 5 has a true state-of-the-art display its not perfect and there is plenty of room for improvements (and competitors) but its the best Smartphone display we have tested to date. Well examine the iPhone 5 display in detail below, but here are the Highlights: it is the Brightest Smartphone we have tested in the Shoot-Out series, it has one of the lowest screen Reflectance values we have ever measured, it has the highest Contrast Rating for High Ambient Light for any Mobile device we have ever tested, and its Color Gamut and Factory Calibration are second only to the new iPad. What are the downsides? The White Point is still somewhat too blue like most Smartphones, and at Maximum Brightness it has a shorter Running Time than the iPhone 4, which is not surprising since it has a larger screen and a larger Color Gamut but roughly the same capacity battery. The Galaxy S III Display: Samsung also features their displays when marketing Smartphones, but they have taken a very different approach they are using Samsungs own OLED displays, a new and rapidly evolving display technology that is very different from LCDs, with its own particular set of advantages and disadvantages. Its a new technology that attracts early adopters, but it has not yet been refined to the same degree as LCDs, which have been mainstream for over 20 years. Its clear that OLEDs in the near future will do to LCDs what LCDs did to CRTs, but we are not there yet So OLEDs have a number of rough spots that show up clearly in our objective Lab testing. Well examine the OLED Galaxy S III display in detail below, but here are the Highlights: the Brightness is about half of the iPhone 5 due to power limits from the lower power efficiency of OLEDs and concerns regarding premature OLED aging. The Color Gamut is not only much larger than the Standard Color Gamut, which leads to distorted and exaggerated colors, but the Color Gamut is quite lopsided, with Green being a lot more saturated than Red or Blue, which adds a Green color caste to many images. Samsung has not bothered to correct or calibrate their display colors to bring them into closer agreement with the Standard sRGB / Rec.709 Color Gamut, so many images appear over saturated and gaudy. Running Time on battery is less than the iPhone 5 due to the lower power efficiency of OLEDs, even given that the Galaxy S III has a much larger battery capacity and much lower Brightness. The Galaxy S III has a PenTile OLED display, which has only half of the number of Red and Blue sub-pixels as in standard RGB displays, like those on the iPhones. The eyes resolution for color image detail is lower, so this works well for photographic and video image content, but NOT for computer generated colored text and fine graphics because it produces visible pixelation, moiré, and other very visible artifacts, so a PenTile display is not as sharp as its pixel Resolution and PPI would indicate. PenTile technology does have advantages in manufacturing, aging and cost. For a more detailed analysis see our Samsung Galaxy S OLED Display Technology Shoot-Out.
