    Hefei Visionox Technology Co., Ltd. Hefei China

  • Xiaokang Zhou
    Kunshan Visionox Technology Co., Ltd. Kunshan China


  • Visible moiré pattern can be significant and detrimental for antenna-on-display screens. A novel simulation algorithm substantially improves speed and efficiency over conventional raytracing while accounting for diverse patterns and real structures. Thus, the visibility of moiré patterns of antenna-on-display can be minimized to ensure superior visual appearance.
