Rollable OLED panel targets 60-inch Ultra HD TVs
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 3 cm without affecting the function of the display.
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.
The transparent OLED panel claims 30 percent transmittance which was achieved by adopting the company’s transparent pixel design technology. LG Display has lowered the haze of the panel which is generated by using circuit devices and film components to a level of two percent. The development improves transmittance performance of a display because the transmittance of existing transparent LCD panels is around 10 percent.
“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.
