It is the ultimate in portable TVs – a giant screen you can just roll up and carry away with you. LG today showed off a working 18inch version – and says a 60 inch screen could go on sale in 2017.
The Ultra HD the screen uses a special film instead of plastic as backing to allow the blind to be wheeled 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.
The jury can be rolled upward to a radius of 3cm without affecting the use of the display. This proves that LG Display can bring reliable TVs of more than 50 inches to the securities industry in the future, the firm stated.
‘LG Display pioneered the OLED TV market and is today chairing 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 get an Ultra HD flexible and transparent OLED panel of more than 60 inches, which will have a transmittance of more than 40 percent and a curve radius of 100R, thereby guiding the future display market.’
LG Display used high molecular substance-based Polyimide film as the backplane of the flexible panel instead of conventional plastic to reach the maximum curvature radius. The Polyimide film also helped cut the heaviness of the panel to significantly improve its flexibility.
As for the transparent OLED panel, it boasts 30 percent transmittance, which was accomplished by taking the company’s transparent pixel design technology.
LG Display has successfully lowered the haze of the jury, which is generated by using circuit devices and film components to a grade of 2 percent. With this breakthrough development, the society has been able to improve greatly the technology level of the transparent display.
Believing that the transmission of existing transparent LCD panels is about 10 percent, this new panel offers significantly improved transmittance.
The University of Houston researchers has produced an entirely new stretchable and transparent electrical conductor, bringing the potential for a fully cell phone or a flat-screen television that can be closed and held under your arm closer to reality.
The gold electrodes produced by Ron and his research associates Chuanfei Guo and Tianyi Sun at UH, along with two fellows at Harvard University, provide good electrical conductivity as well as transparency and flexibility, the researchers said in a paper in Nature Communications.
