It was reported by Korea Herald that Cupertino Tech Giant Apple will be using selected OLED displays in the year 2017 for their top handsets iPhone. Apple may just have its better screen technology than it has had for its new iPad Pro. As per, the business considerations there are no partnership possibilities with Korean giant as of now. As per the recent reports that had come out that Apple was considering OLED displays for its devices. As, OLED Displays far better to the LCD screen. Also, the aggressive competition between Apple and Samsung argues that against a supplier relationship agreement that would make Apple once again dependent on Samsung for a critical iPhone component i.e. Display. Since, many other Apple competitors started using Active Matrix Organic LED displays (AMOLED), one of the criticism that Apple faces is that displays are inferior. This has been pointed out by Apple critics that devices have had poor old clumsy way for their device and Apple was falling behind the times. Apple has been known to bring in the technologies early.

Apple usual explanation for not having better screen is that they are just defending their margins, and LCD also offers lower cost compared to AMOLED screen. There is some truth in it, to be quite frank. But, we are not quite convinced that this would stop Apple from anything. On the other hand, AMOLED manufacturers are arguing on other end that the bill of materials is quite smaller. AMOLED displays quite simple and also require no backlight at all. If AMOLED really offered a superior display, Apple would probably be attracted to it by virtue of being simpler, lighter and thinner.

AMOLED displays are already superior. But, they have been ignoring many of the problems with them, and also by the media. One of the most important problems with AMOLED is its limited display lifetime, especially the blue pixels, and colour and intensity non-uniformity across the display. The limited lifetime of blue OLED materials is quite well known and is the subject of ongoing research. Dr. Steve Forrest, researcher on the subject at the University of Michigan last year summarized the state of the art. Blue pixels typically last less than a percent as long as the green and red pixels. To help blue pixels last longer, AMOLED screen makers typically make them bigger, as can be seen in this magnified image of the Samsung display layout used for the Galaxy S6 and S7.

OLED pixels don’t really die of a sudden death, but they decline gradually in light output from the day one, depending on the amount of use and operating brightness over the device. For that reason, OLED displays are subject to burn in, which isn’t a problem with LCDs at all.
