Layered Flat Cable Layout for Cleaner Display Housing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with FPC cables lack a neat appearance due to the presence of cable covers, making it difficult to easily couple or separate flat cables from FPC cables, which complicates the integration of display panels and housing components.
Innovation Solution
The design eliminates the cable cover, allowing for a flat cable configuration with multiple layers that can be easily connected or disconnected from an FPC cable, enabling a neater appearance and improved flexibility in cable management by using a stepped form FPC cable that matches signal and power terminal positions between flat and round cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cable cover is used to shield the flat cable, then the flat cable is protected and organized, but the appearance becomes less neat and cable coupling becomes more difficult
Solution Approach 1:
The patent removes the cable cover component entirely from the system. Instead of using a separate cable cover to shield and organize the flat cable, the design relies on the cable's own structure (multiple layers with signal and power terminals) to provide both protection and organization, thereby eliminating the covering step and making cable coupling more straightforward
2Object-affected harmful factors
If a cable cover is used to shield the flat cable, then the flat cable is protected and organized, but the appearance becomes less neat
Solution Approach 1:
The cable cover is completely removed from the design. The flat cable itself, with its multi-layer structure containing signal terminals and power terminals, serves as the visible element without requiring an additional protective covering, thereby achieving a cleaner and more integrated appearance
Solution Approach 2:
The protective and organizational functions previously performed by the separate cable cover are merged into the flat cable's own multi-layer structure. The cable layers themselves provide both protection and organization, eliminating the need for a separate aesthetic covering component
3Length of moving object
If the flat cable includes multiple layers, then the width is reduced and wiring flexibility improves, but the cable structure becomes more complex
Solution Approach 1:
The patent transitions from a single-layer cable structure to a multi-layer configuration, stacking signal terminals and power terminals in different layers. This vertical arrangement in the third dimension reduces the horizontal width of the cable while organizing the complex wiring structure in a more compact and manageable way

AI summary
A display device is disclosed. The display device includes a body, a housing separated from the body and configured to transmit/receive signals to/from the body, and a cable coupling the housing and the body, wherein the cable includes a flat cable located in at least part of the cable and having a flat shape, and a round cable located in at least another part of the cable and having a round shape. According to the present invention, the flat cable has a narrow width by including a plurality of layers, and thus wiring of signal terminals and power terminals can be easily changed between the flat cable and the round cable.
