A transparent screen is demanded in various applications. Our proposition is to use a membrane of colloidal liquid. We developed an ultra-thin and flexible BRDF screen, which is soap film exposed to ultrasound. The transparency of the film is controlled by ultrasound so that it modifies projected images to be realistic, distinctive, and vivid. A multi-layered 3D screen is developed by placing the multiple films and changing their transparencies alternately and adequately. The film also can be deformed by higher-amplitude ultrasound. The proposed screen contributes to the real world as the first prototype of a new concept of programmable screen.
