LG shows of the transparent screen, and you can roll it up

It's no longer a curved TV, but a rollable TV which can be rolled up to a radius of 3cm without affecting the function of the display. The portable TV is also transperent when not in use.

LG showed off a working 18inch version of its rollable TVs and says a 60 inch screen could go on sale in 2017.

The Ultra HD screen uses a special film instead of plastic as backing to allow screen to be rolled into a tight tube for transport.

The flexible OLED panel has a high-definition class resolution of 1200 X 810 with almost 1 million mega-pixels

This proves that LG Display can bring rollable TVs of more than 50 inches to the market in the future, the firm said.

'LG Display pioneered the OLED TV market and is now leading the next-generation applied OLED technology,' said 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.'
