Optical microscopy images of seven plasmonic colour filters illuminated by white light
Only a small percentage of backlight actually makes its way out through the multiple layers that make up the ubiquitous LCD displays we use today. That may change with the development of new filter technology at the University of Michigan. White light is sent through tiny, precisely spaced gaps on nano-thin sheets of aluminum and is said to result in brighter, higher definition color reproduction. Other benefits of the technology include efficiency gains and simpler manufacturing.
