As far as providing Active Matrix OLED (AMOLED) screens, Samsung is a reliable company that has factories that are sufficiently advanced to deliver the volume of screens needed to produce a range of range such as the iPhone X. Even so, stringent quality requirements imposed by Apple stretching to the limit of production capacity, the access of other smartphone manufacturers to AMOLED screens delivered by Samsung is virtually blocked
Unfortunately, while Samsung is making huge profits by delivering premium screens to its main rival in the smartphone market, the other Asian manufacturers still share the limited production capacity of some LG Display, Panasonic and Sony
But things will not stay that long, Huawei Technologies, Oppo and Xiaomi Technology giants looking at alternatives to AMOLED screens. Of particular interest is a new type of illumination for conventional LCD screens, called the mini LED, which allows cutting and shaping the screen according to the shape of the case, just like AMOLED solutions. The result could be smartphones with a similar design to those using AMOLED solutions delivered by Samsung, but less expensive
Meanwhile, Apple is also negotiating with LG Display, and the company will become the second AMOLED screen vendor to a 6.5 "iPhone.
In the longer term, Apple could adopt a technology called microLED, capable of improving color saturation, brightness and efficiency of OLED screens, recognized for the tendency to consume more energy than LCDs when used at full brightness
