The IFA 2014 event starts next week (on September 5th, in Berlin) and I think it's going to be a very interesting trade show.
We have three confirmed unveiling events for next week. Samsung will show the Galaxy Note 4. It's pretty much confirmed that the new large smartphone will use a 5.7" QHD Super AMOLED display, but some reports suggest Samsung will also show a premium variant with a curved flexible OLED panel (I don't think this is likely, but you never know).
LG will unveil a new circular smartwatch (which seems to resemble the Moto 360). Not much is known yet, but reports from Korea suggested before that LG is developing a flexible-OLED smartwach. looking at the mostly-black user-interface photo LG showed in their teaser video, it makes sense they'd want to use an OLED display to conserve power. Talking about the Moto 360, Motorola will finally officially launch the device, which unfortunately uses an LCD display.
We will probably see a few more wearable gadgets, and it's likely that some will adopt OLEDs: small PMOLED displays and small flexible OLEDs are the most interesting display panels to watch for. While some smart watches use larger, flat AMOLED panels, I think that most people want a slimmer, better looking device.
Asus is said to be developing an AMOLED watch - and they may unveil it next week. Some recent reports suggest that Samsung will release its six (!) smart watch within the year - and the Gear 3 will sport a curved OLED panel. Yes, it's going to be an interesting trade show...
Of course the most anticipated wearable is Apple's iWatch. Apple does not unveil new products at tradeshows, so we'll have to wait longer to see their product. Hopefully, it too will sport a flexible OLED.
