Solution Overview

Problem

Existing multi-view 3D image display methods and parallax barrier designs are limited in their ability to generate diverse 3D images and provide effective view separation, especially when the display screen is set for portrait mode, as they are restricted by specific slant angles and cannot cover all types of parallax barrier designs, including lenticular and slant-and-step configurations.

Innovation Solution

A method for generating multi-view 3D images using modified formulas for sub-pixel data arrangement and a parallax barrier structure design that allows for variable slant angles and horizontal displacement phases, enabling the creation of a range of 3D images and view separation effects suitable for both landscape and portrait modes, including the use of vertical strip, slantwise strip, and lenticular configurations.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing multi-view 3D image display methods are used, then view separation can be achieved, but the ability to generate diverse 3D images is limited and cannot cover all types of parallax barrier designs

Engineering Contradiction:
Improveability to generate diverse 3D imagesVSAvoidparallax barrier design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying the sub-pixel data arrangement formulas to accommodate different slant angles and horizontal displacement phases. The general formulas allow dynamic adjustment of parameters such as slant angle θ, horizontal displacement Δ, and view number n, enabling the system to generate diverse 3D images including slantwise strip, vertical strip, and lenticular configurations without requiring different hardware designs.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent achieves universality by creating a unified mathematical framework that can handle multiple parallax barrier types (slantwise strip, vertical strip, lenticular, slant-and-step) through a single set of general formulas. This multi-functional approach allows the same display system to generate various 3D image types by simply changing the input parameters rather than requiring separate dedicated systems for each configuration.

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

2Adaptability or versatility

If specific slant angles are used in parallax barrier designs, then view separation can be achieved, but the designs cannot cover all types of parallax barrier configurations including lenticular and slant-and-step

Engineering Contradiction:
Improvecoverage of parallax barrier designsVSAvoiddesign configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses parameter changes by introducing variable slant angles θ and horizontal displacement phases Δ in the general formulas. These parameters can be adjusted to match different parallax barrier configurations - for example, setting θ=0 for vertical strip, specific values for slantwise strip, and appropriate combinations for lenticular and slant-and-step designs, thereby achieving broad coverage without increasing physical device complexity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies dynamics by making the slant angle and displacement phase adjustable parameters rather than fixed values. This dynamic approach allows the system to adapt to different parallax barrier types by changing the parameters in real-time, enabling flexible configuration for various display modes including portrait and landscape orientations.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If conventional sub-pixel data arrangement is used, then display compatibility is maintained, but diverse 3D image generation and effective view separation cannot be achieved

Engineering Contradiction:

Solution Approach 1:

The patent modifies the sub-pixel data arrangement by changing the mathematical formulas to include additional parameters such as slant angle θ, horizontal displacement Δ, and view number n. These parameter changes enable the system to generate diverse 3D images with proper view separation while maintaining compatibility with conventional display hardware through software-based formula adjustments rather than hardware modifications.

Inventive Principle:
