Now that we’ve understood that, Until very recently Samsung was apple’s principal screen supplier, and continues to provide large numbers of screens to them for their current generation of products. What has changed is display sources for upcoming products, where apple has dropped Samsung and has sought out other suppliers – most notably japan’s Sharp.

What is important about OLEDs is that they are very thin, use very low power and are very, VERY, tough. They can also be made to be flexible or permanently curved, as well as have brighter more vivid colors. However those colores are made using different processes, and making the full range of basic colors necessary to be able to combine on a display to make all other colors has not been easy. This is especially true as it pertains to the color blue. Making blue has been expensive and blue LED’s even today are not as long lived as other colors, so there are questions over the overall longevity of LED displays that are not replaced frequently (such as TVs). Today, Samsung is by far the world’s biggest producer of OLED displays, annd few companies are as far ahead in LED display development as they are. By apple being excluded from this market this means that other companies can potentially gain access to key display technology prior to apple, thus making their products more attractive to consumers (I know i would want a more vibrant, tougher screen that used less power). This is especially true of Samsung branded products seeing that Samsung is quite possible the most advanced manufacturer of mobile phones as well.

THAT, is the issue.
