Technology, HardwareJune 30, 2023Next-Generation reflective displays: Researchers develop energy-efficient and flexible visual solutionsResearchers at the University of Illinois Urbana-Champaign have developed flexible displays controlled by robotic flapping fins and liquid droplets that are highly versatile and energy efficient. Inspired by the adaptive skins of chameleons and octopuses, the capillary-controlled fins allow for switchable optical and infrared light multi pixel displays. By manipulating the volume and temperature of fluid-filled pixels, the fins can change their orientation and communicate via infrared energy. The displays can convey information, change color, and even send messages visible only through infrared cameras. However, limitations include the unavailability of commercially viable pumps to control the fluids and the display's sensitivity to gravity, only functioning optimally in a horizontal position. The researchers aim to address these challenges by using smaller droplets that are less affected by gravity. This groundbreaking technology shows promise for energy-efficient, scalable, and flexible displays that can be placed on curved surfaces. It has the potential to revolutionize the market for large reflective displays, offering a new breed of energy-efficient and flexible visual solutions.
