Curious gadgets and futuristic technology are part of DerConsumer Electronics Show (CES) in Las Vegas. To zubegeistern trade press on site, South Korean manufacturer LG this time brought a huge television, which rolls out like a Alufolieaus of an oversized box. 65 inches measures device in DerDiagonalen, bringing it to a 4k resolution. The Bildqualitätunterscheide are not from that of a current TV, claim Dieanwesenden journalists.
The roll TV does not come into trade for time being; Bislanghandelt is just a prototype. However, after LG had introduced two Jahrenbereits at CES first version, it has done itself in development of foldable Displaysviel. The first electronic devices for consumers, which can be rolled out, bent or adapted to ir carriers, could still 2018erscheinen – and thus open up new areas of application UndProduktkategorien in coming years.
This is made possible by organic light emitting diodes, oleds in short. They have been coming in Bildschirmenvor for many years, in form of amoleds for example in smartphones and tablets. They consist, in simple words, of one or more organic FILMENZS wiping two electrodes. Flows current, electrons wander through film Underzeugen depending on state light in each individual pixel. Because OLEDskeine need backlight, y are not only energy-saving, but also very thin. They can even be printed by ink jet on a surface.
Rapid developmentThe technology is not new; The idea dates from 1970s. At that time Gabe's first attempts at an "electronic paper". The ErstenOLED screens in consumer area came to Denmarkt in nineties and first flexible OLEDs emerged shortly after Jahrtausendwendeauf. Already 2008, Nokia introduced with Morph concept Einesbiegbaren phone, which wraps around wrist. Funktionierthat did not, but it anticipated some of ideas that now imagine companies like LG, Samsungoder Lenovo.
"The developments have been going on for at least ten years," says Armin Wedel, Forschungsbereichsleiterfür functional polymer systems and OLED expert at FraunhoferIAP in Potsdam talking to time online. Why y have not yet made a breakthrough, on one hand, is due to lack of resilience of flexible substrates used, on which OLEDs are built today. "OLEDs on glass substrates are quite good in three-dimensional form, but are still very fragile in some cases. Plastic substrates, i.e. films, require sufficient barrier to protect oleds from water vapor and oxygen, so that y work for a long time, "says Wedel.
On or hand, it is important to how and to what extent screens are rolled and bent. " A screen that can be rolled up like a poster or sogarfalt or kinky like paper is still in future ", SagtWedel. In case of Unrollable TV from LG, however, bending radius is predetermined, so pressure on materials is calculated accurately. Such applications, which could be used for example in living rooms, as advertising media at events or even Inselbstfahrenden cars, are for Wedel mittelfristigrealistischer. Especially since not only actual display, but also dieElektronik underneath, such as conductor tracks suitably built flexibly Seinmüssen.
