A transparent smartphone will be launched this year, the multi touch device will use Switchable OLED Glass technology to illuminate applications when touched.Taiwan-based Polytron Technologies is close to revealing a prototype of the new device that uses conductive OLED liquid crystal molecules to display images.

When the phone is off the molecules align to form a milky composition, but when switched on they realign to form text, icons, and other images. The electric current is carried through transparent wires.

“It will happen near the end of 2013. Trust me,” said Polytron general manager Sam Yu.
 
The Daily Mail claims that the device still has some parts that are not transparent, including a SD card and SIM card. The microphone, camera, and batteries are also visible, and will be hidden behind a dark glass cover when the model goes into production.

Yu said the company will develop a smaller lithium ion battery that would be much less noticeable. When complete, the phone will have a dual-sided multi-touch display on its front and back.
