Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional LED display panels are formed by assembling a plurality of LEDs on a substrate to display an image in the entire display area, then the image display function is achieved, but the manufacturing process becomes complicated and the manufacturing cost increases
Solution Approach 1:
The display area is divided into three separate pixel arrays (first color, second color, third color) arranged in a specific pattern. Each pixel array contains multiple pixels of a specific color, and these arrays are distributed across the substrate rather than using a full matrix of individual LEDs for every pixel location. This segmentation reduces the total number of LEDs required while maintaining full-color display capability through the combination of different color arrays.
2Use of energy by moving object
If conventional LED display panels use a large number of LEDs across the entire display area, then complete image coverage is achieved, but the power consumption increases
Solution Approach 1:
The display is segmented into three color-specific pixel arrays instead of using individual LEDs for every display element. By organizing LEDs into color-grouped arrays and distributing them across the substrate, the total LED count is reduced, which directly reduces power consumption while maintaining the ability to display full-color images through the combination of different color arrays.
3Ease of manufacture
If conventional LED display panels assemble a large number of LEDs on a substrate, then the display area is fully covered, but the manufacturing cost increases
Solution Approach 1:
The display structure is segmented into three color-specific pixel arrays with LEDs distributed across the substrate rather than densely packed in a traditional matrix. This segmentation reduces the total number of LEDs required, which lowers material costs and simplifies the manufacturing process while maintaining complete color display coverage through the coordinated operation of different color arrays.
