OLED smartphone display can be stretched, bent, rolled and even dented - but won't break
Samsung is set to unveil a new kind of flexible OLED display for smartphones and tablets that can be stretched, bent, rolled and even dented up to 12mm - but won't break.
The display will be shown off at the Society for Information Display (SID) show in Los Angeles, California this week. Other developments that Samsung will be showing off include a glasses-free 3D OLED and an LCD display with 2,250ppi.
That's according to the Korea Herald, which reports that the soon-to-be-announced 9.1in stretchable OLED can be bent, rolled and deformed, and even dented "like a balloon" up to 12mm deep.
"While current flexible OLED is able to be transformed in only one side, this stretchable OLED can be transformed - whether curved, bended or rolled - in both sides, above and below," a Samsung Display spokesperson said, adding that it can be used for applications such as wearables, automotive displays and Internet of Things devices.
A 5.0in glasses-free 3D unit will be shown as well. Due to the high contrast and refresh rate of OLED technology, this should have some real advantages over LCD for showing 3D content.
Lastly will be a 1.96in 4k (3,840 x 2,160) LCD display (2,250ppi), which is designed for VR, AR and holograms. Such a high pixel density should avoid the ‘screen-door' effect (visible pixels) that plagues today's virtual reality (VR) headsets.
To date the only headset we've tried that exhibits no screen door was a prototype at CES 2016 from Royole Corporation, which was actually a ‘mobile theatre', not VR. Ironically, perhaps, it used a Samsung OLED.
There is no release date for any of the products that Samsung is due to show at SID, which is really a show for demonstrating design concepts rather than finished products.
However, reports claimed in January that the long-rumoured ‘Galaxy X' (aka Project Valley) foldable smartphone/tablet will be launched in the third quarter this year, quite possibly at the IFA trade show in Berlin this September.
