A Taiwan-based tech firm has promised to launch a transparent mobile by the end of 2013.
Polytron Technologies has already begun marketing a transparent multi-touch.
The company's prototype uses what they call Switchable Glass technology.
According to the Daily Mail, that's a conductive OLED using 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 report said.
Electric current is carried through transparent wires, it added.
The handset 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. (ANI)
