Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display apparatuses have a high number of peripheral circuit boards and lead wires due to separate signal boards being connected via Flexible Printed Circuit boards (FPCs) or wires, leading to increased cost.
Innovation Solution
Integrating the T/CON functional module for timing control and at least one other functional module into a single printed circuit board, reducing the number of FPCs and lead wires, and thus lowering manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If respective signal boards are arranged on different carriers and connected via FPCs or lead wires, then electrical connection between signal boards is achieved, but the number of peripheral circuit boards and lead wires becomes too large and cost increases
Solution Approach 1:
The patent integrates the T/CON functional module and other functional modules (gate line drive IC, data line drive IC, system functional module, power functional module) onto a single printed circuit board. This merging of previously separate signal boards eliminates the need for multiple FPCs and lead wires, directly reducing device complexity while maintaining reliable electrical connections through direct PCB traces.
2Reliability
If respective signal boards are arranged on different carriers and connected via FPCs or lead wires, then electrical connection between signal boards is achieved, but manufacturing cost increases
Solution Approach 1:
By consolidating multiple functional modules onto one printed circuit board, the patent reduces the total number of components (FPCs, lead wires, separate carriers) that need to be procured, assembled, and tested. This integration simplifies the manufacturing process, reduces assembly steps, and lowers overall manufacturing cost while ensuring reliable electrical connections through standardized PCB mounting.
3Device complexity
If T/CON functional module and other functional modules are integrated into one printed circuit board, then the number of peripheral circuit boards and lead wires decreases and cost is reduced, but integration complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the integrated printed circuit board into distinct functional modules (T/CON module, gate line drive module, data line drive module, system module, power module), each with dedicated mounting areas and connection interfaces. This modular segmentation within a single PCB makes the integration process more manageable, allowing standardized assembly procedures and reducing the complexity burden of integration.
4Ease of manufacture
If T/CON functional module and other functional modules are integrated into one printed circuit board, then manufacturing cost is reduced, but design complexity increases
Solution Approach 1:
The patent designs the printed circuit board with universal mounting structures and standardized connection interfaces that can accommodate different functional modules. The PCB incorporates multiple connection terminals and power supply lines that can serve various modules, allowing a single board design to fulfill multiple functions. This universality simplifies the overall design process despite the integrated nature, as standardized patterns can be reused across different module configurations.
