Hologram is an ideal method for naked eye three-dimensional (3D) display. Metasurfaces consisted of subwavelength structures show great potentials in light field manipulation which is suitable for hologram design to overcome the shortages of common computer-generated holography (CGH). However, there are long-pending challenges to achieve dynamic meta-holography in visible range, such as low frame rate, low frame number and low efficiency. In this work, we demonstrate a new design of meta-holography in visible range based on space division multiplexing metasurface and high-speed dynamic device which can achieve 228 different holographic frames and an extremely high frame rate (maximum of frame rate, 9523 fps). The metasurface consists of silicon nitride (SiNx) nanopillars with a high modulation efficiency (more than 70%). This method can satisfy the needs of holographic display as well as be suitable for many different research fields, such as laser fabrication, optical storage, optics communications and information processing.
