Overlapping Partial Pad Sealing for Display Device Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving effective waterproof and dustproof capabilities due to issues with sealing member production efficiency and air gaps formed during manufacturing, leading to reduced productivity and compromised performance.
Innovation Solution
The use of a combining-type pad configuration with overlapping partial pads, where a first partial pad and a second partial pad overlap, is implemented to enhance sealing efficiency and reduce air gaps, allowing for superior waterproof and dustproof functions while improving manufacturing productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-piece type sealing member is used, then waterproof and dustproof protection is provided, but material waste increases and productivity decreases
Solution Approach 1:
The sealing member is divided into multiple separate pieces (first sealing member and second sealing member) that can be produced independently from a single material sheet. This segmentation allows each piece to be manufactured separately and then assembled, enabling repeated production from remaining material portions while maintaining the waterproof and dustproof sealing function through the combined arrangement of the multiple pieces along the periphery of the display device.
2Reliability
If a single-piece type sealing member is used, then sealing is provided, but air gaps form during manufacturing
Solution Approach 1:
The sealing member is divided into multiple separate pieces (first sealing member and second sealing member) that are positioned along different portions of the periphery. This segmentation creates gaps between the separate pieces that allow air to escape during the manufacturing process when the cover substrate is attached, preventing air gap formation while the overlapping portions of the segmented sealing members maintain effective sealing against dust and moisture.
3Productivity
If multiple partial pads are used to improve productivity, then material waste is reduced, but sealing effectiveness may be compromised
Solution Approach 1:
Multiple separate sealing members (first sealing member and second sealing member) are combined by making them overlap with each other at their adjacent ends along the periphery of the display device. This merging of multiple segmented pieces creates a continuous sealing barrier that maintains waterproof and dustproof effectiveness while allowing each piece to be manufactured separately for improved productivity and reduced material waste.
