Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If Mini LED is used as a backlight source or direct display, then brightness and contrast are improved, but power consumption and heat generation increase
Solution Approach 1:
The patent divides the display into multiple light emitting units (pixels) arranged in an array, with each unit independently controllable. The electrode wire structure is also segmented into first and second wires that alternately connect to first and second light emitting units, enabling localized power delivery and reducing overall power consumption through selective activation of display regions.
Solution Approach 2:
The patent implements alternating connection patterns where first electrode wires connect to first light emitting units and second electrode wires connect to second light emitting units. This local differentiation allows for optimized power distribution and heat management across different regions of the display, addressing power consumption and heat dissipation issues.
2Measurement precision
If light emitting units are densely arrayed, then display resolution is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The patent segments the electrode connection system into alternating first and second wires, each serving specific light emitting units. This segmentation creates thermal zones that can be managed independently, allowing heat from densely packed light emitting units to be dissipated more effectively through distributed connection points and reduced current density in individual wiring paths.
Solution Approach 2:
The patent extends the electrode wire arrangement into multiple dimensions by having first electrode wires extend in a first direction and second electrode wires extend in a second direction (perpendicular to the first). This two-dimensional electrode network distributes heat dissipation pathways across multiple spatial dimensions, improving thermal management in high-density displays.
3Productivity
If electrode wires pass through light emitting unit regions, then connection efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the electrode wire system into first electrode wires and second electrode wires with distinct connection patterns. First electrode wires pass through first light emitting unit regions and connect to first light emitting units, while second electrode wires pass through second light emitting unit regions and connect to second light emitting units. This segmentation simplifies the manufacturing process by allowing separate fabrication and alignment of different wire types, reducing overall complexity despite maintaining high connection efficiency.
Solution Approach 2:
The patent establishes predetermined alternating patterns for electrode wire connections before final assembly. The first and second electrode wires are pre-configured to connect to specific light emitting units in an alternating sequence, allowing for pre-testing and quality control before complete assembly, thereby reducing manufacturing complexity and improving connection reliability.
