Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D stereoscopic image display devices face challenges in effectively converting 2D images into 3D stereoscopic images, as they rely on binocular disparity and require complex light path manipulation to separate left-eye and right-eye images for each viewer.
Innovation Solution
An image control panel comprising a first substrate with a lens electrode and a second substrate with a common electrode, separated by a liquid crystal layer, where specific voltage patterns are applied to create an electric field that alternates between different polarities to form Fresnel zone plates, allowing for the conversion of 2D images into 3D stereoscopic images by altering the light path for each eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex light path manipulation is used to separate left-eye and right-eye images, then 3D stereoscopic image display is achieved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical light path manipulation with an electric field-based control system. By applying different voltages to the common electrode and lens electrode, the liquid crystal layer's refractive index is modulated to direct light to different eyes, substituting mechanical complexity with electrical control.
Solution Approach 2:
The patent changes the electrical parameters (voltage levels) applied to the electrodes to control the liquid crystal layer's optical properties. By varying the voltage difference between the common electrode and lens electrode, the system dynamically adjusts light direction to achieve 3D display without mechanical light path changes.
2Reliability
If binocular disparity method is used for 3D display, then stereoscopic image is achieved, but the system requires separate image paths for left and right eyes increasing complexity
Solution Approach 1:
The patent merges the left-eye and right-eye image paths into a single display panel. The liquid crystal layer acts as a spatial light modulator that directs different portions of the same image to different eyes based on the viewer's position, eliminating the need for separate physical image paths while maintaining binocular disparity.
Solution Approach 2:
The patent introduces the liquid crystal layer as an intermediary between the single image source and the viewer's eyes. This intermediary dynamically redirects light based on voltage control, enabling a single image to be perceived differently by each eye without requiring separate image generation systems.
