==METHOD AND SYSTEM FOR PATTERNING A LIQUID CRYSTAL LAYER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240036516 titled 'METHOD AND SYSTEM FOR PATTERNING A LIQUID CRYSTAL LAYER

==Simplified Explanation==

The patent application describes a method for creating an optical master using a nanoimprint alignment layer and a liquid crystal layer. The optical master is positioned above a photo-alignment layer and is illuminated, causing light to propagate through the nanoimprinted alignment layer and the liquid crystal layer. The diffracted light then strikes the photo-alignment layer, transferring the pattern from the liquid crystal layer to the photo-alignment layer. A second liquid crystal layer is deposited onto the patterned photo-alignment layer, which aligns the molecules of the second liquid crystal layer. The patterned photo-alignment layer can be used as a replica optical master or as a diffractive optical element for directing light in optical devices like augmented reality display devices.

* A nanoimprint alignment layer and a liquid crystal layer are used to create an optical master.
* The optical master is positioned above a photo-alignment layer.
* Illuminated light passes through the nanoimprinted alignment layer and the liquid crystal layer.
* The diffracted light strikes the photo-alignment layer, transferring the pattern to it.
* A second liquid crystal layer is deposited onto the patterned photo-alignment layer.
* The second liquid crystal layer aligns with the patterned photo-alignment layer.
* The patterned photo-alignment layer can be used as a replica optical master or as a diffractive optical element.

== Potential Applications ==
* Augmented reality display devices
* Optical devices requiring light direction

== Problems Solved ==
* Creation of an optical master using a nanoimprint alignment layer and a liquid crystal layer
* Transferring patterns from a liquid crystal layer to a photo-alignment layer

== Benefits ==
* Simplified method for creating an optical master
* Versatile application in various optical devices
* Improved alignment of liquid crystal layers


==Original Abstract Submitted==

an optical master is created by using a nanoimprint alignment layer to pattern a liquid crystal layer. the nanoimprint alignment layer and the liquid crystal layer constitute the optical master. the optical master is positioned above a photo-alignment layer. the optical master is illuminated and light propagating through the nanoimprinted alignment layer and the liquid crystal layer is diffracted and subsequently strikes the photo-alignment layer. the incident diffracted light causes the pattern in the liquid crystal layer to be transferred to the photo-alignment layer. a second liquid crystal layer is deposited onto the patterned photo-alignment layer, which subsequently is used to align the molecules of the second liquid crystal layer. the second liquid crystal layer in the patterned photo-alignment layer may be utilized as a replica optical master or as a diffractive optical element for directing light in optical devices such as augmented reality display devices.
