There is no doubt transparent phones look cool, but it seems impossible to create; as also pointed out in comments by many in our transparent iPad concept post shared earlier. However, this could soon be a reality as Taiwan-based optical glass specialists company Polytron Technologies are already working on a transparent smartphone, and the results have been promising so far.

The company has even released the early stage smartphone prototype demo video showing the hardware. The secret ingredient to make this work is switchable glass, which contains the liquid crystal molecules creating the transparent display using electric current.
