  Holographic displays generate Three-Dimensional (3D) images by displaying
single-color holograms time-sequentially, each lit by a single-color light
source. However, representing each color one by one limits brightness in
holographic displays. This paper introduces a new driving scheme for realizing
brighter images in holographic displays. Unlike the conventional driving
scheme, our method utilizes three light sources to illuminate each displayed
hologram simultaneously at various intensity levels. In this way, our method
reconstructs a multiplanar three-dimensional target scene using consecutive
multi-color holograms and persistence of vision. We co-optimize multi-color
holograms and required intensity levels from each light source using a gradient
descent-based optimizer with a combination of application-specific loss terms.
We experimentally demonstrate that our method can increase the intensity levels
in holographic displays up to three times, reaching a broader range and
unlocking new potentials for perceptual realism in holographic displays.
