Solution Overview

Problem

Current naked-eye 3D display systems suffer from image crosstalk and poor energy efficiency when viewer eye positions change, leading to suboptimal 3D display quality.

Innovation Solution

A 3D display control system comprising a display module, an eye position detection device, and a lens plate with adjustable lens equivalent units, which modulate light to specific eye visual areas, and a control device that adjusts pixel and lens positions based on detected eye movement information to maintain precise image alignment and reduce crosstalk.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lens plate uses fixed lens equivalent units, then the device complexity is reduced, but the adaptability to changing eye positions deteriorates

Engineering Contradiction:
Improveadaptability to eye position changesVSAvoidcomplexity of adjustable lens system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lens plate transforms from a static structure to a dynamic one by enabling the lens equivalent units to move along the display module surface. This allows the system to adapt to changing eye positions in real-time, resolving the contradiction between fixed structure simplicity and adaptive capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lens plate is divided into multiple independent lens equivalent units that can be individually positioned. This segmentation allows selective adjustment of specific lens units corresponding to detected eye positions, achieving adaptability without requiring complete system reconfiguration.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the system continuously adjusts lens positions to track eye movements, then the 3D display quality is improved, but the energy consumption increases

Engineering Contradiction:
Improve3D display qualityVSAvoidenergy consumption of adjustment mechanism
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous adjustment, the system performs lens positioning at discrete moments based on detected eye position changes. The lens units remain stationary between adjustments, reducing energy consumption while maintaining display quality when needed.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The eye position detection device provides feedback to the control device, which triggers adjustments only when actual eye position changes are detected. This feedback-based triggering avoids unnecessary continuous adjustment, balancing quality maintenance with energy efficiency.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If the lens equivalent units are positioned precisely to match pixel units, then the image alignment precision is improved, but the device complexity increases

Engineering Contradiction:
Improveimage alignment precisionVSAvoidcomplexity of positioning system
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The lens equivalent units are designed to self-align with pixel units through the control device's positioning commands based on eye position data. The system uses the existing pixel structure as a reference framework, allowing precise alignment without requiring additional complex positioning infrastructure.

Inventive Principle:
Principle #25Self-service
