Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If light emitting components are connected in parallel (conventional design), then the device complexity is low and ease of manufacture is high, but the luminous efficiency is insufficient
Solution Approach 1:
The invention divides the pixel area into multiple sub-pixel areas and further segments light emitting components into different types (first, second, and third light emitting components) with different sizes. This segmentation allows series connection of components while maintaining manageable device complexity through systematic organization.
Solution Approach 2:
Different types of light emitting components with different sizes are assigned to different sub-pixel areas based on local requirements. The first light emitting components (largest size) are placed in first subpixel areas, second components in second subpixel areas, and third components (smallest size) in third subpixel areas, optimizing luminous efficiency locally while maintaining overall system manageability.
2Illumination intensity
If larger light emitting components are used, then the luminous efficiency and brightness are improved, but the area occupied by each component increases
Solution Approach 1:
The pixel area is segmented into multiple sub-pixel areas that can accommodate different sizes of light emitting components. This allows the use of larger components (first light emitting components) in specific sub-pixel areas while maintaining compact overall pixel design through the division into first, second, and third subpixel areas.
Solution Approach 2:
Different sized light emitting components are deployed in different sub-pixel areas according to local brightness requirements. Larger first light emitting components are used in first subpixel areas where higher brightness is needed, while smaller third light emitting components are used in third subpixel areas, optimizing the balance between brightness and area utilization.
3Loss of energy
If series electrical connection is implemented, then the luminous efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The light emitting components are segmented into different types (first, second, and third components) with different sizes and are arranged in specific sub-pixel areas. This segmentation facilitates systematic series connection within each sub-pixel area while maintaining ease of manufacture through standardized placement patterns and clear differentiation between component types.
