Screen on bubble soap

Audiences may soon see films on soap bubbles, after researchers develop image-to-screen technology made from bubble film.

A team of international experts used sound waves to interfere with the properties of the bubble film and to create a plane or 3D image.

Bubble mixtures are far more complex than those sold to children, but soap is still the main ingredient.

Experts claim this is the world's thinnest transparent display, according to the BBC.

"In general terms, the surface of the soap bubble is a very thin film. It allows light to shine through and express its own color scheme , "said lead author Yoichi Ochiai of the University of Tokyo.

"We built an ultra-thin and flexible BRDF display using a mixture of two colloidal liquids ," Ochiai said. BRDF is short for the 'bidirectional reflectance distribution function' , a term used to determine how light is reflected on a light-emitting surface.

This is a work of the University of Tokyo in cooperation with Tsukuba University and Carnegie Mellon University (USA).

If you pair several bubble displays together, viewers will be able to enjoy 3D effects or even a three-dimensional projection suspended in the air.

Before the invention, the world witnessed a lot of effort to create non-traditional screen, such as the screen on the water and the screen on the tape.
