Breathable Display Panel With Through Holes For Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable display devices with non-breathable flexible panels cause discomfort and operational issues due to heat and sweat accumulation at contact sites with the human body.
Innovation Solution
Incorporating through holes in the display panel, specifically in pixel areas, to enhance breathability without affecting the display effect, allowing for heat and sweat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If through holes are added to the display panel to improve breathability, then heat and sweat dissipation is enhanced, but the display area is reduced due to sacrifice of pixel areas
Solution Approach 1:
The display panel incorporates through holes in the substrate to create a porous structure that enables breathability. These through holes allow air circulation and dissipation of heat and sweat from the contact site between the wearable display device and the human body, directly addressing the harmful accumulation effects.
Solution Approach 2:
The through holes are strategically positioned in specific pixel areas where they can provide breathability functionality without uniformly reducing the entire display area. By localizing the breathability features to specific regions, the patent maintains display quality in non-through-hole areas while achieving the desired thermal and moisture management.
2Ease of operation
If through holes are formed in pixel areas to enable breathability, then comfort and operation are improved, but manufacturing complexity increases
Solution Approach 1:
The through holes are formed in the substrate during the manufacturing process before subsequent layers are deposited. This preliminary action integrates the breathability feature into the base structure, avoiding the need for additional post-processing steps and reducing overall manufacturing complexity despite the added functionality.
