LG sviluppa un display flessibile da 18-inch basato su tecnologia OLED

Con il comunicato stampa che vi presentiamo più in basso in lingua originale, LG Display ha annunciato il completamento della fase di sviluppo di un pannello flessibile da 18-inch, basato sulla tecnologia OLED, che, come si evince dalle foto che vi mostriamo di seguito, può funzionare correttamente anche se arrotolato in maniera tale da formare delle zone cilindriche la cui sezione ha un raggio pari a 3cm.

Il pannello annunciato da LG lavora con una risoluzione video di categoria high definition, anche se non elevatissima, e più in dettaglio pari a 1200 X 810 pixel.

In accordo al produttore, LG Display, già pioniere nell'ambito dei televisori basati su pannelli OLED, si annuncia quindi come l'azienda leader anche per le soluzioni OLED di nuova generazione; più in dettaglio, LG promette lo sviluppo di display flessibili e trasparenti, in grado di equipaggiare i nuovi televisori Ultra HD con dimensioni da 60-inch in su, fissando come due date il 2017.

LG Display, the world’s leading innovator of display technologies, announced today that it has developed a 18-inch flexible OLED panel that is rollable as well as a 18-inch transparent OLED panel. With these new panels, LG Display shows that it has already acquired fundamental technologies to lead the large-sized flexible and transparent display market.

The flexible OLED panel has a high-definition class resolution of 1200 X 810 with almost 1 million mega-pixels. The panel’s curvature radius is 30R. The panel can be rolled up to a radius of 3cm without affecting the function of the display. This proves that LG Display can bring rollable TVs of more than 50 inches to the market in the future.

LG Display used high molecular substance-based polyimide film as the backplane of the flexible panel instead of conventional plastic to achieve the maximum curvature radius. The polyimide film also helped reduce the thickness of the panel to significantly improve its flexibility.

As for the transparent OLED panel, it boasts 30 percent transmittance, which was achieved by adopting the company’s transparent pixel design technology. LG Display has successfully lowered the haze of the panel which is generated by using circuit devices and film components to a level of 2 percent. With this breakthrough development, the company has been able to improve greatly the technology level of the transparent display. Considering that the transmittance of existing transparent LCD panels is around 10 percent, this new panel offers significantly improved transmittance.

"LG Display pioneered the OLED TV market and is now leading the next-generation applied OLED technology. We are confident that by 2017, we will successfully develop an Ultra HD flexible and transparent OLED panel of more than 60 inches, which will have transmittance of more than 40 percent and a curvature radius of 100R, thereby leading the future display market." said In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display.
