In practice , dr yin thinks liquid-crystal technology is so well developed that his microspheres will never catch up .
实际上，殷博士觉得液晶技术已经发展得很好了，所以它的微球体不可能赶上这个技术。
The researchers demonstrated the long-distance optical manipulation using two types of particles : agglomerates of carbon nanoparticles with diameters of 100 nanometers to 100 micrometers and carbon-coated hollow glass microspheres with diameters of 50-100 micrometers .
The spheres at the intersections would then rotate . But the speed of change may be less important in an otherwise static image on an outdoor billboard than it is on a television , so a scanning process that moved in increments across rows of microspheres would probably be just as effective .
Dr yin , a chemist , is collaborating with a team at seoul national university in south korea to produce a control system to switch the colour of microspheres on display devices so that they can form moving images .
