Flexible Display Module Shielding and Waterproofing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in simultaneously implementing a shielding structure to protect digitizer panels from external magnetic fields and a waterproof structure to prevent moisture and foreign materials, as these structures often interfere with each other.
Innovation Solution
A flexible display module is designed with a shielding structure comprising multiple shielding members and reinforced plates, and a waterproof structure with waterproof members between reinforced plates, ensuring the digitizer panel operates effectively while being protected from external elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shielding structure is applied to protect the digitizer panel from external magnetic fields, then the digitizer panel can operate with designated quality, but the shielding structure may interfere with the waterproof structure
Solution Approach 1:
The shielding structure is divided into multiple shielding members (first shielding member, second shielding member, third shielding member) positioned at different locations and orientations. Each shielding member segments the magnetic field protection function, allowing the waterproof structure to be integrated between them without compromising overall shielding effectiveness while reducing structural interference.
Solution Approach 2:
Different shielding members are positioned to provide localized magnetic field protection where needed. The first shielding member is disposed on the rear surface of the digitizer panel, the second shielding member is positioned between the magnet and digitizer panel, and the third shielding member is disposed on the rear surface of the reinforced plate. This localized approach allows the waterproof structure to pass through gaps between shielding members.
2Object-affected harmful factors
If a waterproof structure is applied to protect electronic components from moisture and foreign materials, then electronic components are protected, but the waterproof structure may interfere with the shielding structure
Solution Approach 1:
The waterproof structure is positioned as an intermediary element between the shielding members and the magnet. Specifically, the waterproof structure is disposed between the first and second shielding members, and between the second and third shielding members, allowing it to fulfill its protective function while the shielding members maintain their magnetic field protection function without direct interference.
Solution Approach 2:
The waterproof structure is nested within the gaps and spaces between the shielding members and reinforced plates. The waterproof structure including first and second waterproof members is disposed on the rear surface of the reinforced plate, fitting into the layered structure without compromising the shielding function.
3Reliability
If multiple shielding members and waterproof members are integrated, then both shielding and waterproofing functions are achieved, but the device structure becomes more complex
Solution Approach 1:
The reinforced plate serves multiple functions: it provides structural reinforcement for the digitizer panel, serves as a mounting surface for shielding members (second shielding member and third shielding member), and provides a base for the waterproof structure. This multi-functionality reduces the need for separate components and simplifies the overall device structure despite the integrated shielding and waterproofing functions.
