Taiwanese firm Polytron Technologies has revealed the world’s first fully transparent smartphone prototype. As you can see in the pictures above and below, the prototype device is almost fully transparent. The only components visible on the device are the board, chips memory card and camera.
The rest of the device is a piece of glass that sports a small touchscreen (also transparent) located in the center of the device. According to Polytron, its technology may be available by the end of 2013.
Polytron has been working on glass-based technology for a while and has developed “Polyvision Privacy Glass” whereby liquid crystal molecules randomly orientated inside the glass line up when an electric charge is applied. So, while the glass is opaque when the power is off, fire it up and the sheet becomes see-through. This would have uses in a smartphone to cover up non-transparent parts like the SIM card.
The smartphone features a touchscreen interface in the center giving (at the moment) very basic functionality as there’s no OS. Despite this, Polytron is planning to market the technology by the end of the year.
In nature, jellyfish have the unique ability to extract pigment-free color directly from the quantum, so to speak, through precisely configured scales or undulating cilia — tiny “hairs” that protrude from a larger cell. They use these bio-antennea to blink out a measured photon whenever the distance between these hairs matches the wavelength of the illumination that strikes them.
Polytron explains the technology – “When the power is off, the liquid crystal molecules are randomly oriented [way] that scatters incident light and the screen becomes opaque. When electricity is applied, the liquid crystal molecules line up, the incident light passes through, and the screen looks clear.”
The smart glass is optically inhomogeneous, and in simple words it means, that when light enters this medium they get scattered all over, whereas in normal glass it pass through easily. The phenomenon occurs because of presence of polymer dispersed liquid crystal. In general these crystals are scattered randomly over the medium, hence blocking the light.But when a current is applied to this medium the crystal gets charged up and reorient, allowing lights to pass through easily.
