Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If display panels are connected to form a large-screen display, then the screen size is increased, but bezels appear at connection portions causing image discontinuity

Engineering Contradiction:
Improvescreen sizeVSAvoidimage discontinuity
Core Design Contradiction:
Area of moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes the bezel structure from the connection portions between display panels. By eliminating the bezel that causes visual discontinuity, the invention achieves seamless image continuity across multiple panels while maintaining the large-screen display area.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges adjacent display panels by positioning pixel circuits of one panel to overlap with light emitting elements of adjacent panels. This overlapping arrangement eliminates visible boundaries and creates a unified large-screen display without bezels.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If pixel circuits are disposed between light emitting elements, then dead space is reduced, but manufacturing complexity increases

Engineering Contradiction:
Improvedead spaceVSAvoidmanufacturing complexity
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The patent utilizes the vertical dimension by disposing pixel circuits at different positions relative to light emitting elements. Specifically, pixel circuits of odd-numbered rows are disposed above light emitting elements while even-numbered rows are disposed below, effectively utilizing vertical space to minimize dead space without complicating horizontal manufacturing processes.

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

Solution Approach 2:

The invention segments the display panel into odd-numbered and even-numbered pixel rows with different circuit arrangements. This segmentation allows for systematic minimization of dead space while maintaining manufacturing feasibility through standardized production processes for each segment type.

Inventive Principle:
Principle #1Segmentation

3Object-generated harmful factors

If scan drivers and data distributors are disposed between pixels, then image continuity is improved, but device complexity increases

Engineering Contradiction:
Improveimage continuityVSAvoiddevice complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements multi-functional components that serve both driving and signal distribution functions. The scan driver and data distributor are integrated into the pixel circuit structure, allowing these components to perform multiple functions simultaneously and reduce overall device complexity while ensuring image continuity across panel boundaries.

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