Bent Flexible Circuit Board Shielding for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in effectively managing the exposure and protection of flexible circuit boards and main circuit boards, which can lead to static electricity generation and noise interference, affecting the reliability and performance of the display module.
Innovation Solution
The implementation of a display device design that includes bent flexible circuit boards and a main circuit board configuration, with a first cover covering the flexible circuit boards and main circuit board, and a second cover covering exposed areas of the flexible circuit boards, to shield static electricity and block noise, utilizing insulating and conductive materials to ground the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible circuit boards and main circuit boards are exposed without adequate covering, then the device structure is simpler and easier to manufacture, but static electricity generation and noise interference increase, reducing reliability
Solution Approach 1:
The cover structure is divided into multiple segments: a first cover for covering the flexible circuit board and main circuit board, and a second cover for covering exposed areas of the flexible circuit board. This segmentation allows targeted protection of different components while maintaining manufacturing simplicity.
Solution Approach 2:
The first and second covers act as intermediary shielding elements between the circuit boards and the external environment. These covers block static electricity and noise interference, protecting the circuit boards without requiring complex integrated shielding structures.
2Shape
If flexible circuit boards are bent and disposed under the display panel, then the display device achieves a sleeker design and better integration, but the circuit boards are more vulnerable to damage and exposure
Solution Approach 1:
The first cover extends in a first direction and the second cover extends in a second direction, creating multi-dimensional shielding coverage. This allows the bent flexible circuit boards to be protected from multiple angles and directions, addressing the vulnerability introduced by their bent configuration.
Solution Approach 2:
The second cover specifically targets and covers the exposed areas of the flexible circuit board, providing localized protection where the circuit board is most vulnerable due to its bent and exposed configuration, rather than requiring complete coverage of the entire circuit board.
3Object-affected harmful factors
If more covering structures are added to protect circuit boards, then static electricity and noise interference are reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The shielding function is segmented into two separate covers: the first cover for the flexible circuit board and main circuit board, and the second cover for exposed areas of the flexible circuit board. This segmentation allows each cover to be manufactured and installed independently, simplifying the overall manufacturing process while providing comprehensive protection.
