Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional quadrilateral sub-pixel structures are used, then manufacturing is simpler, but display quality and tightness are insufficient

Engineering Contradiction:

Improvedisplay qualityVSAvoidsub-pixel structure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies asymmetry by using triangular arrangements of sub-pixel structures instead of traditional quadrilateral layouts. The centers of three adjacent sub-pixel structures form a triangle, creating an asymmetric configuration that improves tightness and display quality while maintaining manufacturing feasibility through standardized fabrication processes

Inventive Principle:

Principle #4Asymmetry

2Manufacturing precision

If sub-pixel structures are arranged with loose spacing, then manufacturing is easier, but tightness and display quality deteriorate

Engineering Contradiction:

Improvetightness of sub-pixel structuresVSAvoidmanufacturing difficulty

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent transitions from two-dimensional quadrilateral arrangements to a three-dimensional triangular configuration where the centers of sub-pixel structures form triangles. This dimensional reorganization allows for tighter packing and improved display quality while the triangular geometry provides natural alignment references that simplify manufacturing processes

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An array substrate includes a plurality of sub-pixel structures disposed on a first substrate and including a first sub-pixel structure, a second sub-pixel structure and a third sub-pixel structure. The first sub-pixel structure has a first center and includes a first reflecting region and at least one first penetrating region. The second sub-pixel structure has a second center and includes a second reflecting region. The third sub-pixel structure has a third center and includes a third reflecting region. The first sub-pixel structure, the second sub-pixel structure and the third sub-pixel structure are adjacent to each other and display different colors. The first center, the second center and the third center form a triangle in a top view. At least two of a geometric shape of the first sub-pixel structure, a geometric shape of the first reflecting region and a geometric shape of the first penetrating region are not quadrilaterals.
