A team led by India-origin scientists has developed world’s first full color, ultra-thin and flexible display that is just few microns thick. Scientists say that their revolutionary display is inspired by nature. Generally, displays used in mobile, tv, etc are made of light source and glass plates, also they are rigid and are not foldable. While designing the new display, researcher closely observed animals like chameleons, octopuses and squids that have thin, flexible and color changing skin that doesn’t need any light source and emit its own light.
“All manmade displays – LCD, LED, CRT – are rigid, brittle and bulky. But you look at an octopus, they can create colour on the skin itself covering a complex body contour, and it’s stretchable and flexible,” said Professor Debashis Chanda from the University of Central Florida in US, who led the study.
To design the ultra-thin display, researchers took ultra thin crystal molecules sandwiched over a metallic nanostructure shaped like microscopic egg carton. The structure absorbed some light wavelengths and reflected ambient light around it. In addition, the amount of different colors reflected can be controlled by the voltage applied.
While explaining Chanda said that the interaction between crystal molecules and nanostructured metallic surface played a vital role in generating full-color display. The new display is even thinner than the human hair which is about 100 microns thick.
Scientists believe that the new design is far ahead than the previous designs that could only produce limited colors. The research could have major implications in various fields including displays of televisions, computers and even mobile. In fact, scientists believe that with the help this revolutionary study we can design color changing clothes and within a flick of a second we will be able to change clothes depending on different occasions.
Moreover, Chanda said that now his team is working on making the display cost-effective so that it becomes feasible for everyone to use the ultra-thin, flexible and full colored display.
