Screen with ... concrete

Two students - a technical major and an architecture major - have jointly researched and successfully produced the world's first transparent concrete screen.

The concrete screen is made of concrete blocks embedded with optical cable, acting as pixels, transmitting light to display images.

The display technology of the screen is also unique. Behind the screen is another layer of fiber optic cable, which acts as a screen to receive images to recreate. The image displayed on the screen will be an image taken from another source and not directly taken and processed.

A projector will act as the light source for the screen image. The image will project on the screen at the back and will be re-displayed on the main screen in front.
