HOLOGRAPHIC VR DISPLAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240168290 titled 'HOLOGRAPHIC VR DISPLAY

The holographic display described in the patent application consists of an illuminator, a spatial light modulator (SLM) connected to the illuminator, and an ocular lens attached to the SLM. The SLM comprises first and second pixelated panels that modulate the illuminating light beam in both amplitude and phase. One of the SLM panels may include a liquid crystal (LC) panel, such as an in-plane switching (IPS) panel, while another may feature an array of piston-type micromirrors.

  • The holographic display includes an illuminator, SLM, and ocular lens.
  • The SLM consists of first and second pixelated panels for modulating light.
  • One SLM panel may contain a liquid crystal panel like an IPS panel.
  • Another SLM panel may have an array of piston-type micromirrors.

Potential Applications: - Holographic displays for entertainment and gaming - Medical imaging for enhanced visualization - Automotive heads-up displays for improved safety

Problems Solved: - Enhanced image quality with spatial modulation of light - Versatile display technology for various applications
