Solution Overview

Problem

Existing display panels with a four-color configuration using a checkered barrier pattern often block some colors, preventing effective color separation for multi-view and three-dimensional displays.

Innovation Solution

The display panel incorporates a barrier section with light blocking and transmitting regions alternately arranged in rows and columns, allowing two sub-pixels of each color to be continuously disposed, ensuring all colors pass through the barrier layer, even with a checkered pattern, enabling color separation of perspective.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If a checkered barrier pattern is used with four-color pixels, then the distance between pixel and barrier layer can be increased, but some colors are blocked and color separation of perspective is not performed

Engineering Contradiction:
Improvedistance between pixel and barrier layerVSAvoidcolor separation of perspective
Core Design Contradiction:
Length of stationary objectVSReliability

Solution Approach 1:

Each pixel is segmented into four color regions (R, G, B, W) arranged in a 2x2 grid pattern. This segmentation allows the barrier layer's checkered pattern to align with specific color regions, enabling selective light blocking and transmission for different viewing perspectives while maintaining color integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the pixel array are assigned different barrier layer configurations. Specifically, light blocking regions of the barrier layer are positioned to correspond with specific color sub-pixels in a checkerboard pattern, creating local optical properties that enable perspective-dependent color separation while allowing other regions to transmit light normally.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If sub-pixels are arranged in striped structure of three colors, then processing margin is limited, but with four colors in row and column direction, processing margin is increased

Engineering Contradiction:
Improveprocessing marginVSAvoidcolor separation of perspective
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The pixel structure transitions from a conventional 3-color striped arrangement to a 4-color 2x2 grid arrangement, creating an asymmetric color distribution pattern. This asymmetric layout provides greater processing margin during manufacturing while the barrier layer's checkered pattern compensates to ensure proper color separation for different viewing perspectives.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The sub-pixel arrangement moves from a one-dimensional striped structure to a two-dimensional 2x2 grid structure within each pixel. This dimensional change increases the distance between adjacent pixels, providing greater processing margin, while the barrier layer's checkered pattern maintains optical functionality by selectively blocking light from specific color regions.

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

3Quantity of substance

If four-color pixel configuration is used, then more colors can be displayed, but with checkered barrier pattern some colors are blocked preventing color separation

Engineering Contradiction:

Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The invention merges the four-color pixel configuration (R, G, B, W) with the checkered barrier layer pattern into a unified optical system. The barrier layer's light blocking and transmitting regions are strategically positioned to work in conjunction with the four color sub-pixels, enabling both full-color display and perspective-dependent color separation to function simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The optical parameters of the barrier layer are changed by positioning light blocking regions to correspond with specific color sub-pixels in a checkered pattern. This parameter adjustment allows the system to selectively block or transmit specific colors based on viewing perspective, enabling color separation while maintaining the four-color display capability.
