Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with multiple panels under a single cover window, effective heat dissipation is hindered, leading to reduced panel lifespan, especially for organic light-emitting diode panels, due to the complexity and inefficiency of attaching separate heat-dissipating plates to each panel.
Innovation Solution
A heat-dissipating plate design featuring interconnected flat portions and bridges forming a step structure, attached to multiple display modules, which increases the heat-dissipation area and absorbs thermal expansion shocks, while being integrated to reduce attachment processes and enhance manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate heat-dissipating plates are attached to each display panel, then heat dissipation effectiveness is improved, but the number of attachment processes and device complexity increase
Solution Approach 1:
Multiple separate heat-dissipating plates are merged into a single integrated heat-dissipating plate that can simultaneously contact multiple display panels. The plate includes multiple contact portions (first contact portion, second contact portion, etc.) that can be attached to different panels in one process, reducing the number of attachment operations while maintaining effective heat dissipation for each panel.
Solution Approach 2:
The heat-dissipating plate is designed with multi-functional contact portions that can serve multiple display panels simultaneously. Each contact portion is configured to contact a different display panel, allowing the single plate to perform the heat dissipation function for multiple panels, thereby reducing overall device complexity.
2Temperature
If separate heat-dissipating plates are attached to each display panel, then heat dissipation effectiveness is improved, but manufacturing time increases
Solution Approach 1:
Multiple separate heat-dissipating plate attachment operations are merged into a single attachment process. The integrated plate with multiple contact portions can be attached to multiple display panels simultaneously in one manufacturing step, significantly reducing the total time required compared to attaching separate plates to each panel individually.
Solution Approach 2:
The heat-dissipating plate is pre-designed and pre-fabricated with multiple contact portions positioned and configured in advance. This preliminary preparation allows the plate to be ready for simultaneous attachment to multiple panels, eliminating the need for sequential attachment operations and reducing manufacturing time.
3Device complexity
If a single integrated heat-dissipating plate is used for multiple display panels, then attachment processes are reduced, but heat dissipation effectiveness may deteriorate
Solution Approach 1:
The integrated heat-dissipating plate is segmented into multiple distinct contact portions (first contact portion, second contact portion, third contact portion, etc.), each specifically designed and configured to contact a different display panel. This segmentation ensures that each panel receives dedicated heat dissipation contact, maintaining effective heat transfer while using a single integrated plate structure.
Solution Approach 2:
Each contact portion of the integrated heat-dissipating plate is designed with specific local characteristics optimized for its corresponding display panel. The contact portions have different shapes, sizes, and configurations tailored to match the specific thermal and mechanical requirements of each panel, ensuring effective heat dissipation for each individual panel while being part of the overall integrated structure.
