IMAGE DISPLAY APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17986055 titled 'IMAGE DISPLAY APPARATUS

Simplified Explanation

The patent application describes an image display apparatus that includes an eyepiece optical system to guide light from the image display element to an exit pupil. The eyepiece optical system has a correction element with different characteristics in the central and peripheral areas.

  • The eyepiece optical system corrects for color drift in light emitted from the image display element.
  • The correction element is designed to minimize color drift of light emitted from the outermost peripheral portion of the image display element.
  • The characteristics of the correction element are set to reduce color drift of light passing through the peripheral area compared to light passing through the central area.

Potential applications of this technology:

  • Virtual reality headsets
  • Augmented reality glasses
  • Head-up displays in vehicles

Problems solved by this technology:

  • Color drift in image display systems can lead to inaccurate color representation and reduced image quality.
  • The patent addresses this issue by using a correction element with different characteristics in the central and peripheral areas to minimize color drift.

Benefits of this technology:

  • Improved color accuracy in image display systems
  • Enhanced image quality and visual experience for users
  • More realistic and immersive virtual and augmented reality experiences


Original Abstract Submitted

An image display apparatus includes an image display element, and an eyepiece optical system configured to guide light from the image display element to an exit pupil. The eyepiece optical system includes at least one correction element having different characteristics between a central area and a peripheral area different from the central area. When first light is light emitted from a central portion of the image display element, and second light is light emitted from an outermost peripheral portion of the image display element, the characteristics of the at least one correction element are set such that color drift of the second light after pass through the peripheral area from the first light after pass through the central area is less than color drift of the second light before pass through the peripheral area from the first light before pass through the central area.
