==LIGHT GUIDE ELEMENT COMPRISING A DIFFRACTION ELEMENT HAVING A CHOLESTERIC LIQUID CRYSTAL LAYER WITH A PITCH GRADIENT - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18492603 titled 'LIGHT GUIDE ELEMENT COMPRISING A DIFFRACTION ELEMENT HAVING A CHOLESTERIC LIQUID CRYSTAL LAYER WITH A PITCH GRADIENT

==Simplified Explanation==

The patent application describes a light guide element that includes a light guide plate and a diffraction element with a liquid crystal layer. The liquid crystal layer has a unique alignment pattern that changes the direction of the optical axis while continuously rotating in at least one in-plane direction. The refractive index of the light guide plate is 1.70 or higher, and the refractive index of the liquid crystal layer satisfies the condition n-n≠0.

* Light guide element with diffraction element
* Liquid crystal layer with unique alignment pattern
* High refractive index of light guide plate
* Specific condition for refractive indices of light guide plate and liquid crystal layer

== Potential Applications ==
This technology could be used in:
* Holographic displays
* Head-up displays
* Augmented reality devices

== Problems Solved ==
This technology solves issues related to:
* Enhancing display brightness and clarity
