The combination of ultrasonic waves and ultra thin membranes improves the quality of the projection, creating more realistic, distinctive, and vivid images on screen
Researchers at the University of Tokyo have developed a system that uses bubbles as a kind of projection screen based on colloidal liquids
If you ever thought of soap bubbles as small floating movie capsules, you were not alone in your observation. Researchers at the University of Tokyo have developed a system that uses such bubbles as kind of projection screen based on colloidal liquids. The bubbles are made of a thin film, and allow light to create a reflection on one section before passing through other sections. If the reflection can be controlled, then the bubble can be used as a display.
