I do not understand. If the rumor that only one model iPhone could include OLED, why the need for so many suppliers?
I also do not understand why anyone wants OLED for their phone. OLED is less suitable than LED for phone displays. OLED has color shifting and burn-in, performs less well in sunlight, is much less efficient displaying white imagery (have you seen iOS lately?). Sure, OLED is great for TV where you watch continuously moving images indoors. On a phone... it is just an inferior option. If Apple moves to OLED, it is evidence that the marketing and salespeople are now in charge of Apple.
