Liquid Crystal Panel Grating Layer for Naked-Eye 3D Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing naked-eye 3D display technologies require additional laminating processes that increase manufacturing complexity and cost, and overall thickness of liquid crystal modules, making the separation of left-eye and right-eye images cumbersome and difficult to achieve directly on a common liquid crystal cell.
Innovation Solution
A liquid crystal panel with a grating layer comprising alternating light shielding and light transmitting regions, arranged in proximity to the upper substrate, allows for direct separation of left-eye and right-eye images, simplifying the manufacturing process by using alignment films with specific orientations and UV light treatment to align liquid crystal molecules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional laminating processes are used to attach lenses externally to the liquid crystal cell, then naked-eye 3D display capability is achieved, but manufacturing complexity and production cost increase
Solution Approach 1:
The patent merges the grating layer with the liquid crystal cell by forming the grating structure directly within the liquid crystal material itself, rather than attaching separate lens components externally. This integration eliminates the need for additional laminating processes while maintaining naked-eye 3D display capability through the grating structure that separates left-eye and right-eye images.
Solution Approach 2:
The liquid crystal cell is designed to perform multiple functions simultaneously: it serves as both the display element and the grating structure for 3D image separation. The grating layer formed within the liquid crystal cell integrates the functions of image modulation and parallax barrier, reducing the need for separate specialized components.
2Adaptability or versatility
If additional laminating processes are used to attach lenses externally to the liquid crystal cell, then naked-eye 3D display capability is achieved, but overall thickness of liquid crystal module increases
Solution Approach 1:
The patent merges the grating layer with the liquid crystal cell by forming the grating structure directly within the liquid crystal material itself, rather than attaching separate lens components externally. This integration eliminates the need for additional laminating processes while maintaining naked-eye 3D display capability through the grating structure that separates left-eye and right-eye images.
3Adaptability or versatility
If precise attaching process is required at latter stage of assembly to laminate additional spectroscopic means and liquid crystal cell together, then separation of left-eye and right-eye images is achieved, but process difficulty increases
Solution Approach 1:
The grating layer is formed within the liquid crystal cell during the cell fabrication process itself, rather than being added as a separate component in a subsequent assembly step. This preliminary formation of the grating structure eliminates the need for precise attaching operations at later stages, as the grating is already integrated into the cell before assembly.
Solution Approach 2:
The patent merges the grating layer with the liquid crystal cell by forming the grating structure directly within the liquid crystal material itself, rather than attaching separate lens components externally. This integration eliminates the need for additional laminating processes while maintaining naked-eye 3D display capability through the grating structure that separates left-eye and right-eye images.
