LG unveils new paper-thin TV

LG announced that it has developed a new line of 18-inch OLED display panels that are flexible, rollable, and even transparent. The flexible prototype sports an HD class resolution of 1200 X 810 with almost 1 million mega-pixels. The OLED panel is flexible enough to be rolled into a tube that’s a mere 3cm across without affecting the performance of the display.

This shows that LG Display, the world’s largest LCD panel maker, has already acquired fundamental technologies to bring the large-sized flexible and transparent OLED panels.

“LG Display pioneered the OLED TV market and is now leading the next-generation applied OLED technology,” says In-Byung Kang, Senior Vice President and Head of the R&D Center at LG Display.

“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.”

The company also aims to produce rollable TVs at sizes of up to 50 inches in the future.

LG says  that it used high molecular substance-based polyimide film as the backplane of the flexible panel, which enables the product to achieve the curvature radius of up to 30R. The polyimide film also helps reduce the panel thickness, thus improving its flexibility.

The OLED panel boasts 30 percent transmittance thanks to LG Display’s transparent pixel design technology.

Further, the company also incorporated circuit devices and film components in the panel to successfully lower its haze to a level of 2 percent. Given that the transmittance of existing transparent LCD panels is around 10 percent, this new OLED panel is a great advancement in the transparent display technology.
