Engineering Contradiction Analysis
1Length of stationary object
If multiple display modules are coupled using multiple flexible circuit boards to enlarge display size, then the display size is increased, but the flexible circuit boards or space portions are exposed between adjacent display modules, degrading image quality
Solution Approach 1:
The patent combines multiple flexible circuit boards into a single integrated circuit board structure. Instead of using separate flexible circuit boards to connect adjacent display modules, the invention employs one continuous circuit board that spans across multiple display modules, eliminating the gaps and exposed circuit board edges that degrade image quality while maintaining the enlarged display size
Solution Approach 2:
The patent segments the circuit board into multiple regions that can be independently connected to different display modules. The single integrated circuit board is divided into multiple connection regions, each capable of connecting to adjacent display modules, allowing the circuit board to function as both a unified structure and a multi-connected interface
2Length of stationary object
If multiple flexible circuit boards are used to connect display modules in horizontal and vertical directions, then display size is enlarged, but the number of circuit boards and assembly complexity increase
Solution Approach 1:
The patent merges multiple flexible circuit boards into a single integrated circuit board that provides both horizontal and vertical connectivity. Instead of using separate circuit boards for horizontal and vertical connections between display modules, the invention employs one continuous circuit board that integrates both directional connection functions, reducing the total number of circuit boards and simplifying the overall device structure
3Length of stationary object
If display bodies are jointed together using multiple flexible circuit boards with individual mounting processes, then display size is increased, but productivity decreases due to increased number of processes
Solution Approach 1:
The patent combines multiple individual mounting processes into a single integrated mounting process. Instead of separately mounting multiple flexible circuit boards to connect display modules, the invention enables a single mounting process that connects all display modules to the integrated circuit board structure simultaneously, significantly reducing the number of manufacturing steps and improving productivity
