Reversible Connector Wiring Board for Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connection structures for wiring boards face challenges in accommodating different liquid crystal display panel specifications, requiring multiple designs and increasing costs due to the need for different mounting orientations of connectors, which complicates the alignment and manufacturing process, especially with the use of flexible printed circuits.
Innovation Solution
An electrical connection structure featuring a wiring board with a connector that can be mounted in two orientations: one where the inserting direction of the belt-like wiring material is from the display panel end and another where it is from the opposite end, allowing a single type of wiring board to be used for both flat and curved panel specifications, reducing the need for multiple designs and minimizing stress on the wiring material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different mounting orientations of connectors are designed for flat and curved panel specifications, then the FPC can be properly positioned for each specification, but the device complexity and manufacturing cost increase due to multiple wiring board designs
Solution Approach 1:
The connector is designed with symmetric terminal connecting regions and connector fixing regions at opposite ends, allowing the same connector to be mounted in either orientation (first mounting or second mounting) depending on the panel specification. This universal design enables a single wiring board to accommodate both flat and curved panel requirements without needing separate designs for each specification.
2Area of stationary object
If the FPC base portion overlaps the printed wiring boards in flat panels, then space is saved, but stress is applied to the FPC when curved
Solution Approach 1:
The connector mounting orientation is made dynamic and adjustable based on the panel specification. For flat panels, the connector is mounted in the first orientation allowing the FPC base portion to overlap the wiring board and save space. For curved panels, the connector is mounted in the second orientation allowing the FPC to curve externally without overlapping the wiring board, thus avoiding stress concentration and potential damage.
3Length of stationary object
If the dimensions of the printed wiring board are increased for larger display panels, then the panel size requirement is met, but alignment accuracy and manufacturing precision deteriorate
Solution Approach 1:
The system uses multiple printed wiring boards arranged along one side of the display panel rather than a single large board. The connectors enable these segmented boards to be electrically connected in series, allowing the system to achieve the required large dimensions while maintaining manageable sizes for each individual board, thus preserving alignment accuracy and manufacturing precision.

AI summary
This electrical connection structure for wiring boards comprises: a plurality of wiring boards which are arranged along one side of a display panel and distribute electric power and/or an electric signal for driving the display panel; and a connector which is mounted on the wiring boards adjacent to each other, and electrically connects the wiring boards via a belt-like wiring material. Terminal connecting region and connector fixing region of the wiring board are configured to enable both first mounting of the connector with a direction in which the belt-like wiring material is inserted from the display panel end and second mounting of the connector with a direction in which the belt-like wiring material is inserted from an end opposite to the display panel. Thus, the present invention provides an electrical connection structure for wiring boards, in which an insertion direction of a connector can be reversed.
