Solution Overview

Problem

Silicon-based micro displays with irregular edges, such as round or oval edges, often suffer from jagged and colored edges due to inconsistent sub-pixel arrangements, leading to display quality issues like light emission imbalance and color shifting.

Innovation Solution

A display panel design featuring an irregular display region with specifically arranged irregular and regular sub-pixels, where the sub-pixels' dimensions and light emitting areas are tailored to match the edge shape, preventing edge jags and ensuring uniform light emission by using filters to maintain color consistency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If irregular edges (round, arc, oval) are implemented in display screens to meet diverse aesthetic demands, then display versatility and adaptability are improved, but jagged edges and colored edges appear causing display quality deterioration

Engineering Contradiction:
Improvedisplay shape adaptabilityVSAvoidedge display quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by differentiating sub-pixel configurations between edge regions and central regions. Irregular sub-pixels at the edge have different shapes and sizes compared to regular sub-pixels in the center. This localized differentiation allows the display to achieve irregular edges while maintaining uniform light emission and color consistency, resolving the contradiction between shape adaptability and edge display quality.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs asymmetry by designing irregular sub-pixels with non-uniform shapes that match the desired irregular edge contours. These asymmetric sub-pixel configurations enable the display to achieve round, arc, or oval edges while preventing jagged appearances through careful geometric design, thus improving display shape adaptability without sacrificing edge quality.

Inventive Principle:
Principle #4Asymmetry

2Shape

If sub-pixel arrangements are adjusted to match irregular edge shapes, then edge shape conformity is improved, but light emission balance and color consistency deteriorate due to inconsistent sub-pixel configurations

Engineering Contradiction:
Improveedge shape conformityVSAvoidlight emission balance
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The patent implements local quality by creating distinct sub-pixel designs for edge regions versus central regions. Irregular sub-pixels at the edge are specifically shaped to conform to the desired edge contour, while regular sub-pixels in the center maintain traditional configurations. This localized approach ensures that edge shape conformity is achieved without compromising the overall light emission balance and color consistency across the display.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent applies parameter changes by modifying the geometric parameters (shape, size, orientation) of sub-pixels in the edge region while maintaining consistent optical parameters (light emitting area, color characteristics) across all sub-pixels. This allows the irregular sub-pixels to match the edge shape while preserving uniform light emission and color consistency, resolving the contradiction between shape conformity and composition stability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If irregular sub-pixels are used at edges to achieve desired edge shapes, then edge shape adaptability is improved, but sub-pixel arrangement complexity increases leading to manufacturing difficulty

Engineering Contradiction:
Improveedge shape adaptabilityVSAvoidsub-pixel arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent reduces complexity by applying local quality - irregular sub-pixels are used only in the edge region where shape adaptability is needed, while the majority of the display area uses simple regular sub-pixels. This localized approach minimizes the number of complex elements while achieving the desired irregular edge shapes, thereby improving edge shape adaptability without excessively increasing overall device complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs segmentation by dividing the display into distinct regions: an edge region with irregular sub-pixels for shape adaptability, and a central region with regular sub-pixels for simplicity. This segmentation allows complex irregular shapes to be achieved only where necessary at the edges, while the majority of the display maintains simple, easy-to-manufacture regular sub-pixel arrangements, thus balancing adaptability with manufacturing ease.

Inventive Principle:
Principle #1Segmentation
