3D glasses may soon be a thing of the past, as more companies are developing 3D displays that have filters on the display screens. This will enable 3D images to be viewed without glasses and from multiple angles, although the technology still needs perfecting. Singapore’s Temasek Polytechnic, working with the Agency of Science, Technology and Research, is developing a filter using nanotechnology that makes the 3D effects smoother and better from all angles. In two years, consumers can expect to see 3D displays on mobile phones, game consoles and most products which use liquid crystal display.
