Metasurfaces consisting of subwavelength structures show great potential in light field manipulation , which is useful for overcoming the drawbacks of common computer - generated holography .
However , there are long - existing challenges to achieving dynamic meta - holography in the visible range , such as low frame rate and low frame number .
