Augmented reality (AR) is the trend of future life. Until now, many technologies have been developed for AR glass. With the high brightness and light characteristic, we use Micro-LED as the source and the metalenses array to form the collimated light. The image can be projected onto the retina using sequential scanning technology. However, the divergent angle of the collimated light would increase along with the increase in pixel number. In this paper, we simulate the collimation properties of metalenses. To increase the number of pixels, we propose to arrange the pixels on a retina well according to the simulation results. The corresponding results of the simulation and calculation will be shown.
