Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display screens fail to achieve an almost seamless visual splicing effect between display units due to uneven light emission from light-emitting units, which is not adequately addressed by existing solutions.
Innovation Solution
A routing structure for display screens that includes a circuit board, driver chips, and light-emitting units, with specific routing configurations ensuring equal lengths and resistances for all connections, allowing uniform light emission across the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If light-emitting units are disposed at edges of display screens to achieve seamless splicing, then visual continuity between screens is improved, but brightness uniformity across the display deteriorates due to uneven light emission from peripheral light-emitting units
Solution Approach 1:
The patent applies local quality by making different parts of the routing structure have different characteristics. Specifically, the routing paths for peripheral light-emitting units are designed with different lengths and resistance values compared to central units, with compensation elements added to achieve balanced current distribution and uniform brightness across the display surface
Solution Approach 2:
The patent changes physical parameters of the routing structure, specifically adjusting routing path lengths, resistance values, and current allocation ratios. By modifying these parameters, the system compensates for the inherent disadvantages of peripheral light-emitting units and achieves uniform brightness distribution across the entire display
2Area of stationary object
If routing paths are extended to reach peripheral light-emitting units, then light emission coverage is improved, but resistance differences between routing paths increase causing non-uniform brightness
Solution Approach 1:
The patent applies equipotentiality by designing routing paths with equal resistance values despite different lengths. Compensation elements are introduced to balance the electrical potential and current distribution across all light-emitting units, ensuring that peripheral units receive appropriate current to maintain uniform brightness with central units
3Illumination intensity
If equal length routing is implemented for all light-emitting units, then brightness uniformity is improved, but routing complexity and design difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the routing structure into multiple independent routing paths, each with specifically designed characteristics. Rather than using a single uniform routing design, the system segments the routing into multiple paths with different lengths and resistance values, compensated to achieve uniform brightness, thereby managing complexity through modular design

AI summary
A routing structure of a display screen includes a display screen, a circuit board, a plurality of driver chips, a plurality of first light-emitting units, a plurality of second light-emitting units, and a light-emitting unit routing assembly. The first light-emitting units are disposed on opposite sides of the display screen. The second light-emitting units are disposed on a second side opposite to the first side of the display screen. The light-emitting unit routing assembly includes a plurality of first routings and a plurality of second routings. The first routings are connected between at least one of the driver chips and the first light-emitting units. The second routings are connected between the at least one of the driver chips and the second light-emitting units. A length of the first routings is similar to a length of the second routings.
