Shanghai plans to use a bigger range of LED devices - from plasma TVs to crop planting - to reduce energy consumption, city officials said yesterday, Shanghai Daily reported.

The plans are based on the development of the core technology of light-emitting dioxides or LEDs, a task within the city's scientific 2020 development scheme, officials of the Shanghai Science and Technology Commission said.

"We are trying to use LEDs to improve people's lives in a variety of ways," Guo Yansheng, director of the commission's Hi-tech production department, said at the 2008 Shanghai International LED Industry Technology Exhibition that opened yesterday at ShanghaiMart. The show will end tomorrow.
