Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display devices require viewers to wear glasses, limiting their widespread use, while naked-eye 3D displays face challenges in easily switching between 2D and 3D modes.
Innovation Solution
A display module comprising a display panel with three sub-pixels arranged in a triangular pattern and a light modulating component with separate units for adjusting light transmittance to each eye, allowing for easy switching between 2D and 3D modes by controlling the light transmittance of the sub-pixels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If naked-eye 3D display is implemented, then the need for 3D glasses is eliminated and accessibility is improved, but the ability to easily switch between 2D and 3D modes is compromised
Solution Approach 1:
The patent implements dynamic control of light modulating units that can adjust their light modulating states in real-time. By dynamically switching between different light modulating states (first state for 3D, second state for 2D), the display enables easy transition between 3D and 2D modes while maintaining naked-eye 3D capability. This dynamic adaptability resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The patent changes the light modulating parameters of the light modulating units to achieve mode switching. By adjusting parameters such as light transmittance, phase, or polarization state of the light modulating units, the system can transition between 2D and 3D display modes. This parameter-based control enables easy switching while preserving the naked-eye 3D display functionality.
2Manufacturing precision
If separate light modulating units are used for left and right eyes, then 3D display quality is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple light modulating units into a single integrated light modulating component. Instead of using completely separate components for left and right eye light modulation, the invention combines them into one unified structure that can independently control light for each eye. This merging reduces device complexity while maintaining the ability to deliver high-quality 3D display through differential light modulation.
Solution Approach 2:
The light modulating component is designed with multi-functionality, serving both 2D and 3D display purposes through a single unified structure. The same light modulating component can operate in different modes (first light modulating state for 3D, second state for 2D), eliminating the need for separate dedicated components for each function. This universal design reduces overall device complexity while preserving 3D display quality.

Function Achieved in This Case
Enables convenient switching between 2D and 3D displays by differing or matching the gray scales output to each eye, creating a 3D effect through brain fusion of left and right images, while maintaining a 2D mode when necessary.
