Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If data lines are arranged in a conventional straight path through the display area, then the layout is simple and manufacturing is easier, but light transmittance is reduced and display area utilization is limited due to obstruction by electronic components

Engineering Contradiction:

Improvelight transmittanceVSAvoiddata line routing complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The display area is divided into multiple sub-display areas (first, second, third sub-display areas) with different functional characteristics. The third display area is further segmented into bypass areas and non-bypass areas, allowing data lines to take different paths in different segments, thereby optimizing light transmittance in specific regions while maintaining overall functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Data lines are allowed to change their extension direction from a conventional single-direction path to multi-directional routing. The bypass areas enable data lines to extend in different directions (first direction, second direction, third direction) to navigate around electronic components, effectively utilizing the third dimension of spatial routing to improve light transmittance without compromising electrical connectivity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If pixel circuits are arranged to overlap with display elements to save space, then area utilization is improved, but manufacturing precision requirements increase and reliability may be compromised

Engineering Contradiction:

Improvedisplay area utilizationVSAvoidpixel circuit alignment precision

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The pixel circuit arrangement is segmented into different regions: some pixel circuits are arranged to overlap with display elements in non-bypass areas, while other pixel circuits are positioned in bypass areas where they do not overlap with display elements. This segmentation allows the patent to achieve high area utilization in non-bypass areas while maintaining manufacturing reliability in bypass areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different arrangement strategies are applied to different local regions of the display panel. In non-bypass areas, pixel circuits are arranged to overlap with display elements to maximize space utilization. In bypass areas, pixel circuits are positioned separately to facilitate light transmission and simplify manufacturing. This local differentiation optimizes both area utilization and manufacturing precision according to regional functional requirements.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the display panel includes multiple display areas with different functions, then versatility and functionality are improved, but device complexity and design difficulty increase

Engineering Contradiction:

Improvedisplay area functionalityVSAvoiddisplay panel structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display panel integrates multiple display areas with different functions: first display area for conventional display, second display area for enhanced light transmission, and third display area for accommodating electronic components. The bypass area structure serves multiple purposes simultaneously: it facilitates light transmission, accommodates pixel circuits, and enables data line routing, thereby achieving multi-functionality without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bypass areas merge multiple functions into a single structural feature: they simultaneously serve as light transmission channels, pixel circuit placement zones, and data line routing paths. This merging approach allows the patent to achieve high versatility with controlled complexity by combining multiple functions in the third display area rather than creating separate structures for each function.

Inventive Principle:

Principle #5Merging (Combining)
