A Leading Expert Touts The Samsung Galaxy S IV's AMOLED Display

The Samsung Galaxy S IV is probably the most anticipated phone of the year with top of the line specs that make it more than a match for any other phone on the market when it comes to performance. Partnered with this blazing hardware is a camera that is second to none and an extensive range of software features to boot.

With all this hype around the phone, one of the most crucial aspects of the device, the display, has been overlooked, which is odd since the screen is the part of the phone that you both see and interact with 99% of the time. The display is a 1080p AMOLED display, while a full HD display in a 4.99 inch form factor means a blistering 441 ppi, those specifications are now fairly run of the mill for a flagship device including the Sony Xperia Z and HTC One to name a few, the HTC One even features an even denser pixel density of 468 ppi by cramming the 1920 x 1080 display into 4.7 inches.

Well Ray Soneira, a leading display expert and president of DisplayMate has praised Samsung and their inclusion of adaptive display technology or CIE Chromatically Diagram and grayscale. This software allows the user to tweak the display with either 7 automatic settings or 4 manual ones to provide the optimal viewing experience. The reason why Soneira is particularly fond of the ability for users to calibrate the screen is due to his major criticism of AMOLED displays in the past; that they are poorly calibrated; especially when compared to the LCD displays used by Samsung's rival Apple who receive universal praise of the quality and calibration of their displays. The ability of users to change the display settings means the user can not only calibrate their displays, but also tweak settings such as colour saturation to their liking whether they prefer bright, vivid oversaturated colours or a more natural look. The most important aspect of the screen calibration in my opinion has to do with tweaking the colour levels and in particular the 'white point'. Most AMOLED displays have a bluish tint when displaying white. Not only does this make whites appear off-white, but due to the nature of AMOLED displays this will also increase the ageing and power drain of the display because the blue subpixels in an AMOLED display are relatively inefficient when compared to red and green ones. By dropping the intensity of the blue subpixels users can increase their battery life while also obtaining more natural colours. While we won't know how well these settings will work until we manage to get an extended hands/eyes-on, needless to say the ability for user calibration and AMOLED technology does set the Galaxy S IV apart from the rest.
