Solution Overview

Problem

Existing 2D-3D image switching display systems face challenges in easily switching between 2D and 3D modes with limited viewing zones and reduced image quality due to complex movement mechanisms and manufacturing difficulties in lenticular sheet-based systems.

Innovation Solution

A 2D-3D switching display system comprising a backlight, a liquid crystal or OLED panel, and a viewing zone separation unit such as a lenticular lens array or micro lens array, which separates images into left and right eye regions, allowing for easy switching between 2D and 3D modes with improved image quality and manufacturing reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a lenticular sheet-based system is used for 2D-3D switching, then 3D image display is achieved, but the viewing zone is narrow and cross-talk increases in middle viewing zones

Engineering Contradiction:
Improve3D image qualityVSAvoidviewing zone width
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The display system is segmented into two independent display panels instead of using a single lenticular sheet system. Each panel can be independently controlled to display 2D or 3D content, eliminating the narrow viewing zone problem inherent in lenticular sheet-based systems while maintaining 3D image quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically switches between 2D and 3D modes by controlling the two display panels with different image signals. This dynamic control allows the system to adapt to different viewing conditions and eliminates the fixed viewing zone limitation of lenticular sheet systems.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the first optical unit is moved in a curved direction along the lens shape, then 2D-3D switching is achieved, but the movement mechanism becomes complicated

Engineering Contradiction:
Improve2D-3D switching capabilityVSAvoidmovement mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mechanical movement mechanism is replaced by an optical control system using two display panels. Instead of physically moving optical units along curved paths, the system uses electronic control to switch between 2D and 3D modes, dramatically simplifying the mechanism while maintaining switching capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The two display panels serve multiple functions: they can display 2D images, 3D images, and switch between modes. This multi-functionality eliminates the need for complex mechanical movement mechanisms while achieving the same adaptability for 2D-3D switching.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a lenticular sheet system is used, then 3D image display is achieved, but manufacturing and maintenance become difficult

Engineering Contradiction:
Improve3D image display capabilityVSAvoidmanufacturing difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The system is divided into two standard display panels that can be manufactured using conventional techniques. This segmentation eliminates the need for complex lenticular sheet manufacturing processes, making the system easier to manufacture and maintain while preserving 3D display capability.

Inventive Principle:
Principle #1Segmentation
