Flexible Display Gap Dust Removal via Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels in foldable electronic devices and large-sized displays face challenges with dust and particle accumulation due to gaps and static electricity, leading to potential damage and operational issues.
Innovation Solution
Incorporating fans with air outlets positioned to direct airflow through the gaps between the flexible display panel and the main body, which can prevent dust accumulation and remove existing particles, and optionally using ion fans to address static electricity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display panel is designed to be relatively slidable with the body to allow smooth folding and unfolding, then the flexibility and operability of the device is improved, but static electricity is generated due to friction, causing dust and particles to be adsorbed in the gap
Solution Approach 1:
The patent introduces a fan to generate airflow that passes through the gap between the flexible display panel and the body. This pneumatic approach removes dust and particles from the gap by creating a continuous air flow that prevents particle accumulation, thereby resolving the contradiction between operational smoothness and dust prevention.
2Adaptability or versatility
If the flexible display panel is configured to be flexible rather than fixed to allow folding, then the adaptability of the device is improved, but gaps are formed between the panel and the body, making it difficult to completely cover the gap and allowing dust and particles to enter easily
Solution Approach 1:
The patent employs a fan-driven airflow system that directs air through the gap between the flexible display panel and the body. This pneumatic solution creates a protective air curtain that prevents dust and particles from entering the gap while maintaining the flexibility and folding capability of the display panel.
3Adaptability or versatility
If accommodation recesses are provided in the bodies to provide sufficient space for the flexible display panel to be bent, then the functionality of the device is improved, but dust and particles are likely to be accumulated in the accommodation recesses
Solution Approach 1:
The patent introduces airflow through the accommodation recesses using fans. The generated air flow passes through the recesses, preventing dust and particles from accumulating in these spaces while maintaining sufficient bending room for the flexible display panel.
