Bio-luminescent organisms are surely the wonders of nature. And this time around, it was science that was inspired by this natural scope of animal vibrancy! According to a study undertaken by Stephan Link, an associate professor at Rice University, researchers will have the future capacity to develop a special type of advanced LCD display that is influenced by the color-changing ability of cephalopods (like squids and octopuses).
The group lead by Link has been able to develop their full-color display prototype comprising of 5 sq micron pixels. These tiny pixels are made from arrays of ‘hundreds’ of aluminum nanorods, and they have the capacity to convincingly generate red, green and blue hues. Fueled by some electronic tuning, along with the variations in the lengths of the nanorods and the spaces between them, the scientists have successfully demonstrated the richness of these particular colors – which at least equals the vivacity of high-definition LCD displays.
In other words, the precise arrangement of the multitude of nanorods has given the researchers the benefit of HD display, as opposed to “typical muted shades”. Created by what is termed as electron-beam deposition, these arrays consist of 100 nanometers by 40 nanometers ‘rods’ that account for the constitution of the aforementioned 5 sq micron pixels. These micro-pixels in turn are incredibly 40-times smaller than the ones used in regular LCDs!
Of course, just demonstrating a particular tech is often not enough; it also should meet the criteria of commercial practicality. To that end, the researchers hope to utilize many of the similar components found in contemporary display technologies, like liquid crystals and polarizers, along with next-generation materials like polymer sheets. Furthermore, the use of aluminum nanorod arrays have endowed the advantage of permanency over the regular colored dyes (used in most commercial display products), since they won’t fade way from the effects of extensive exposure to lights.
This is what LANP (Rice University’s Laboratory for Nanophotonics) director Naomi Halas, had to say about the developed LCD tech –
We hope to eventually bring all of these technologies together to create a new material that can sense light in full color and react with full-color camouflage displays.
