Sharp & NHK Develop Rollable 30-Inch 4Kp60 OLED Screen: 100 Grams and 0.5 mm Thick

Sharp and NHK have co-developed a new rollable 30-inch OLED display, with a design emphasis on keeping the screen thin and light. The prototype monitor will be showcased at a trade show in mid-November, but the company isn't yet talking about mass production.
The experimental 30-inch OLED display offers a 3840×2160 resolution and a 60 Hz refresh rate, all in a package that is just 0.5 mm thick and weighs 100 grams. The developers say that the screen can be rolled up into a 4 cm diameter cylinder, with the idea of being able to integrate the display into various appliances like furniture. Meanwhile, the technology itself could simplify production of foldable electronics, such as smartphones and tablets.
The flexible 30-inch OLED display is produced by Sharp at one of its factories in Japan using vapor deposition method. The screen uses a film substrate and IGZO thin film transistors to drive OLED elements that use separate RGB subpixels. Meanwhile, NHK’s image processing technologies were used to improve brightness uniformity as well as sharpness of moving objects.
Sharp and NHK will demonstrate their prototype rollable 30-inch OLED display at Intel's BEE 2019 trade show, which will take place in Chiba, Japan, from November 13 to November 15.
Sharp and NHK are not the only companies to develop a rollable OLED screen. Earlier this year LG demonstrated such a TV at CES 2019 and even started to sell its rollable Signature TVs in South Korea.

I kind of want this to be one of the roll-down shades in my camper. Instead of having the TV take up a cabinet, just roll down the shades, and one of them *IS* the TV!JeffFlanagan - Monday, November 11, 2019 - link
As long as there's no other window that would let sunlight hit the front of the screen. An OLED may be a very bad fit for a camper, since they burn easily.ZolaIII - Monday, November 11, 2019 - link
Still more interested in their IGZO's and its future LED miniaturisation as that's what will really berry OLED's.darkswordsman17 - Monday, November 11, 2019 - link
Sounds like a new market for Fruit Roll-ups!ZolaIII - Monday, November 11, 2019 - link
To put it simply to you IGZO is a great material to make smaller diodes/transistors (and pretty much everything else) as it's simply has much better physical property's (conductivity, light emissions & cetera) than silicon & it's mature one unlike Graphen (which is even better but still far from being ready for anything & hard to synthesise). Only reason for a given combo is that OLEDS with soft plastic base that is flexible/rollable are mature and developed for quite some time. OLED's reached their peek regarding ideal density long time ago (about ten years ago) next logical step would be development of IGZO based micro LED's to replace OLED's & not to futuristic one. Silicon really needs a replacement in everything.TristanSDX - Monday, November 11, 2019 - link
OLED is stilll best display technology to make prototypes that will never be mass producedyetanotherhuman - Tuesday, November 12, 2019 - link
For that, I vote for FED / SED
