Sony Unveils Rollable OLED Display
TOKYO: Sony has revealed the most flexible video
display yet. Its new ultra-thin organic light-emitting diode screen can be
rolled up like a scroll. Sony released a video of the prototype super-flexible
OLED, which it intends to demonstrate today at the Society for Information
Display trade show in Seattle.
The video screen is said to be as thin as a human hair--80 micrometers thick. It
can continuously display video while being spooled around a cylinder the size
of a pencil, as Sony demonstrated in the released video. The prototype is
around 4.1 inches across with a resolution of 432-by-240 pixels. It relies on
organic thin-film transistors rather than integrated circuit chips, which allow
its degree of flexibility. The super-flexible OLED will not likely become a
standalone product, but eventually incorporated into mobile devices, Sony said.
Sony was the first electronics maker to bring an OLED video display to market
in 2007 with the 11-inch rigid-screened XEL-1 TV. The model is still for sale
in the United States, while sales have been halted in Japan. LG has since
introduced a 15-inch OLED TV, and has plans to release a 40-incher in 2012. Several
rigid OLED professional video monitors were displayed at the NAB Show in April,
including a 7-inch field version from Sony.

demand in Japan had “run its course.”
