Solution Overview

Problem

Current 3D image display technologies, particularly those using liquid crystal shutter glasses, suffer from image mixing and eye fatigue due to the sequential conversion of images for each eye, leading to suboptimal display quality and limited simultaneous observation by multiple viewers.

Innovation Solution

A method and apparatus that divide a 3D image into frames for each eye and insert compensation frames to prevent image mixing, improving display quality by controlling the timing and light source activation to ensure proper image separation and reduce crosstalk.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If sequential conversion of images for each eye is used in liquid crystal shutter glasses method, then the 3D image can be displayed with time-divisional screen, but image mixing occurs and eye fatigue is generated

Engineering Contradiction:
Improveautomatic image conversionVSAvoidimage separation accuracy
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The patent divides the display area into multiple regions (first region and second region) and assigns different image frames to each region simultaneously. This spatial segmentation eliminates the need for sequential conversion, preventing image mixing and eye fatigue while maintaining reliable image separation for 3D display.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If non-glasses method (parallax barrier or lenticular) is used, then 3D image can be seen without glasses, but observation positions are limited and multiple observers cannot simultaneously perceive high-quality 3D effect

Engineering Contradiction:
Improveglasses-free viewingVSAvoidmulti-observer capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent combines the advantages of both glasses-based and glasses-free methods by enabling the display apparatus to simultaneously support multiple observation positions with high-quality 3D effects. The multi-region simultaneous display approach allows multiple observers to view 3D content without glasses while maintaining image quality, making the system universally applicable to various viewing scenarios.

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

3Ease of manufacture

If images are converted sequentially from top to bottom line-by-line, then the conversion process is simple to implement, but the time difference between eyes causes wrong images to be shown and image mixing occurs

Engineering Contradiction:
Improvesimplicity of conversion processVSAvoidimage timing accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent transitions from sequential temporal conversion (one dimension) to simultaneous spatial display (adding another dimension). By displaying different image frames for different eyes in different regions at the same time rather than converting sequentially, the system achieves accurate image timing and prevents mixing while maintaining implementation simplicity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A method for displaying a three-dimensional (ā€œ3Dā€) image includes; dividing the 3D image input from an external device into a first image frame corresponding to a first eye of a viewer and a second image frame corresponding to a second eye of the viewer, and generating a first compensation frame and a second compensation frame subsequent to the first image frame and the second image frame, respectively, and displaying the first compensation frame and the second compensation frame on a display panel.
