Japanese scientists use soap bubbles to make the world’s thinnest transparent display
 |
Do you believe? Erosive and fragile soap bubbles can also become displays. Japanese researchers not only displayed soap bubbles, but also showed different textures of objects. This soap bubble display is the thinnest transparent display in the world.
University of Tokyo, Tsukuba University and Carnegie Mellon University researchers jointly developed a soap bubble display. This display is not as simple as the soap bubbles that children play, but soap is indeed the main ingredient of the display.
“People know that the surface of a soap bubble is a thin film that can transmit light and show the color of light,†BBC quoted the head of research on the 2nd, professor of the University of Tokyo, Mitsuo Yoichi (transliteration) in the blog The report said, "We used a mixture of two colloidal liquids to create a super-thin and soft display." Researchers said that the traditional display is opaque display, but the new soap bubble display, whether in transparency It is also different from the conventional display in terms of reflection coefficient.
According to the researchers, under the effect of ultrasound, the soap bubble display can display different textures for different images.
Researchers released ultrasound waves through loudspeakers, which “slammed†the film and changed the texture of the image projected on the film to make the image look smoother or rougher.
The soap bubble display can also change the transparency of the image projected on it. The researchers said that this can be achieved by changing the frequency of sound waves.
If you combine several soap bubble screens, viewers can also see stereoscopic effects and even holographic projections.
Don't worry about the solidity of the soap bubble display. The researchers said that due to the use of special glue, even if hard objects pass through the middle, soap bubbles will not burst. (Jingjing Xinhua News Agency for this special feature)
