New liquid crystal can triple the sharpness of TV and computer screens

Scientists have invented a new type of liquid crystal. It allows tv and computer manufacturers to pack three times as many pixels. Also it reduces the amount of power required to run the device by more than 40 percent. This new type of blue-phase liquid crystal is so effective because it bypasses the colour filters used in current screen technology. 'Today's Apple Retina displays have a resolution density of about 500 pixels per inch. With our new technology, 1,500 pixels per inch could be achieved on the same sized screen. This is especially attractive for virtual reality (VR) headsets or augmented reality technology. It must achieve high resolution in a small screen to look sharp when placed close to our eyes.'' says one of the team physicist Shin-Tson Wu from University of Central Florida.
