scientists use LED screens to study animal visual perception of the environment

Although the "visible light" wavelengths that humans can see are relatively narrow, certain animals have more acute environmental vision in the long process of biological evolution. In order to further study the visual perception of the environment of specific animals, a team at the University of Queensland in Australia has developed a low-pixel ultraviolet screen called UV-TV.

The mainstream display screens currently on the market use a mixed color scheme based on red, green and blue (RGB) sub-pixels. However, the UV-TV screen developed by the University of Queensland cleverly blends violet (Violet) and ultraviolet (Ultraviolet) pixels.

 

As shown in the figure, the size of this screen is 1.6×2 inches, and each "pixel" is composed of five colors of LEDs. Although the resolution is as low as 8×12 pixels, scientists still hope to use this to analyze the perception of living things on the surrounding environment.

 

Dr. Karen Cheney said: "We have recently conducted research on the vision of Anemonefish and Nemo. Unlike humans, they are also very sensitive to ultraviolet light."

 

"In addition, related studies have shown that the white stripes on sea anemones can also reflect ultraviolet light. Therefore, we believe that ultraviolet signals can be used to identify each other, and may even participate in group communication."

 

As for how other organisms interact and think about UV signals, further research is still needed.
