Apple sent out press invitations to an event on September 9th. They did not say anything regarding this event, besides saying "wish we could say more". It is widely believed that Apple will reveal the iPhone 6 in this event. Apple's new phone is expected to come with a larger display (some say Apple will unveil two new models, one with a large 5.7" panel) - and it won't be an OLED.
But Apple may also surprise and finally unveil the iWatch smart watch wearable device. .Rumors have been circulating about this device for almost 2 years now. Most of these "reports" suggest a flexible OLED display, around 1.3 - 1.6 inch in size. LG Display is believed to be the exclusive supplier of this display, although there's some speculation that Apple wants Samsung Display to be its second supplier for those plastic-based flexible AMOLEDs.
