Slide Structure Component Layout for Rollable Display Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The layout design of electronic components in slidable electronic devices, such as rollable or slidable structures, is constrained, leading to degraded performance of components like antenna modules due to slide-in/slide-out operations.
Innovation Solution
The electronic components, including antenna modules, are efficiently arranged in the slide structure with an electrical connection member (FPCB) connecting the flexible display and the housing substrate, ensuring optimal performance regardless of slide operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic components are disposed in the housing, then layout design is constrained, but component performance deteriorates due to slide-in/slide-out operations
Solution Approach 1:
The patent divides the housing into multiple spaces (first space and second space) separated by a partition wall. Electronic components are selectively disposed in different spaces based on their functional requirements. This segmentation allows independent optimization of component layouts and reduces interference from slide operations, resolving the contradiction between layout constraints and performance maintenance.
Solution Approach 2:
The patent utilizes the third dimension (vertical direction) by creating multiple stacked spaces within the housing. The first space is positioned above the slide structure while the second space is positioned below it. This vertical dimensionality change allows electronic components to be arranged in multiple levels, expanding layout possibilities without interfering with the horizontal slide-in/slide-out operations.
2Area of stationary object
If antenna module is disposed near the slide structure, then space utilization is improved, but radiation performance deteriorates
Solution Approach 1:
The partition wall divides the housing into distinct first and second spaces, isolating the antenna module in one space from the slide structure in another. This spatial segmentation creates electromagnetic isolation, allowing the antenna module to maintain optimal radiation performance while still utilizing the available internal space efficiently through structured arrangement.
Solution Approach 2:
The partition wall acts as an intermediary barrier between the antenna module and the slide structure. This intermediate structure provides electromagnetic shielding and isolation, preventing the slide operations from interfering with the antenna's radiation patterns while maintaining compact space utilization.
