Apple is indeed circling the wagons around OLED screen suppliers, and we even have the first non-Samsung handset on the market with dual curved AMOLED panel, so the premise is not out of the question. Kevin Wong's exact words are that after Vivo outed the Xplay 5 with its 5.4" OLED screen that slopes to the sides like on the S7 edge, there will be more manufacturers using this technique, including Apple with next year's iPhone.This could only mean one thing - OLED display on an iPhone, as the LCDs that Apple as been employing until now can't really bend due to the fact that they can't be made on plastic, instead of glass substrates.
