• To demonstrate a significant reduction in required pixel count for dynamic holographic displays.

Main Methods:

• Introducing functional pixels that spatially modulate both amplitude and phase of incident light using polynomial functions.
• Utilizing linear phase modulation as a specific case to drastically reduce pixel requirements.
• Leveraging existing technologies like micro mirror arrays for implementation.

Main Results:

• A reduction in pixel count by up to three orders of magnitude (1000x) was achieved.
• Preservation of a significant portion of image details despite the reduced pixel count.
• Feasibility of implementation using current micro mirror array technology.

Conclusions:

• The functional pixel concept offers a viable solution for achieving true 3D dynamic holographic displays.
