Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses using organic light emitting diodes face challenges in balancing heat dissipation and rigidity while maintaining a thin thickness, as increasing the support panel thickness to meet these standards compromises internal space for mechanical engineering applications.
Innovation Solution
A support panel with a three-layer structure, including a first body, a heat absorbing material, and a second body, where the first body absorbs heat from the display panel and transfers it efficiently to the heat absorbing material, which is then dissipated to the outside through the second body, utilizing a double junction structure and high-density beading to increase contact areas for enhanced heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the thickness of the support panel is increased to satisfy heat dissipation and rigidity standards, then heat dissipation performance and structural rigidity are improved, but the internal space for mechanical engineering techniques is reduced
Solution Approach 1:
The support panel is divided into a first body and a second body that are bonded together, creating an accommodation space between them. This segmentation allows the inclusion of heat absorbing material in the internal space without increasing the overall thickness, thereby maintaining internal space while improving heat dissipation performance.
Solution Approach 2:
The heat absorbing material is nested within the accommodation space formed between the first body and the second body. This nesting approach allows the heat dissipation system to be integrated within the existing structure without requiring additional thickness, thus resolving the contradiction between heat dissipation performance and internal space.
2Strength
If the thickness of the support panel is increased to satisfy heat dissipation and rigidity standards, then structural rigidity is improved, but the overall thin profile is compromised
Solution Approach 1:
The support panel employs a composite structure consisting of the first body, heat absorbing material, and second body bonded together. This composite construction enhances structural rigidity through the combined properties of different materials and the bonding interface, while the overall thin profile is maintained by utilizing the internal accommodation space rather than increasing thickness.
Solution Approach 2:
By segmenting the support panel into multiple bonded components (first body and second body), the structure gains enhanced rigidity from the bonding interface and distributed stress paths, while the overall thickness remains controlled. The segmentation allows rigidity improvement without proportional increase in thickness.
3Temperature
If the contact area between the support panel and heat absorbing material is increased to improve heat transfer efficiency, then heat dissipation performance is improved, but the structural complexity is increased
Solution Approach 1:
Instead of increasing the entire support panel thickness to maximize contact area, the invention applies beading structures locally at specific regions where heat transfer is most needed. This partial action approach increases the contact area between the first body and heat absorbing material without proportionally increasing overall structural complexity.
Solution Approach 2:
The beading structures are applied locally on the first body to create increased contact area with the heat absorbing material at critical heat transfer zones. This local quality enhancement improves heat transfer efficiency without requiring complex structures throughout the entire support panel, thus balancing heat dissipation performance with structural simplicity.

Function Achieved in This Case
This configuration effectively reduces the temperature of the display panel by efficiently dissipating heat while maintaining the thin profile and rigidity of the support panel, preventing thermal deformation and ensuring both heat dissipation and structural integrity.
Implementation Method 1
a heat absorbing material accommodated in the accommodation space to receive heat from the display panel that is absorbed by the first body, to thereby reduce an increase in a temperature of the display panel
Implementation Method 2
A contact area between the first body and the heat absorbing material may be increased by the plurality of first beading
Implementation Method 3
a contact area between the second body and the heat absorbing material may be increased by the plurality of second beading
Implementation Method 4
Heat generated by the display panel may be absorbed by the first body and the heat absorbed by the first body may be efficiently transferred to the heat absorbing material through a contact surface that is increased between the first body and the heat absorbing material. Heat transferred to the heat absorbing material may be efficiently transferred to the second body
