Solution Overview
Problem
Foldable display devices face issues with charge accumulation in support plates, leading to electromagnetic interference and degraded display quality due to low electrical resistance.
Innovation Solution
A support plate design featuring a connector with multiple openings and an insulating layer, including chromium carbide or acrylic resin, to prevent charge accumulation, combined with a bridge structure to manage stress and deformation, and materials like stainless steel and polyethylene terephthalate for enhanced electrical resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a support plate is used in a foldable display device, then structural support during folding is improved, but charge accumulation occurs leading to electromagnetic interference
Solution Approach 1:
An insulating layer is introduced as an intermediary between the metallic connector (which provides structural support) and the surrounding environment. This insulating layer prevents charge accumulation on the connector surface while maintaining the mechanical strength and support function of the metallic structure during folding operations.
Solution Approach 2:
The insulating layer is applied specifically to the connector portion of the support plate where charge accumulation occurs, rather than coating the entire support structure. This localized treatment addresses the electromagnetic interference problem at the specific location while preserving the overall structural integrity and support function of the metallic support plate.
2Ease of manufacture
If the support plate structure is simplified, then manufacturing ease is improved, but charge accumulation and electromagnetic interference worsen
Solution Approach 1:
The insulating layer is applied to the connector surface before final assembly of the support plate components. This preliminary coating ensures that charge accumulation is prevented from the outset, eliminating the need for additional charge dissipation mechanisms or complex grounding structures that would complicate manufacturing.
