Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OLED panels have a relatively short service life due to heat generated during operation, which is exacerbated by higher brightness and larger sizes, leading to excessive heat and reduced lifespan.
Innovation Solution
Incorporating a heat-dissipating layer above the OLED device within the OLED substrate, which can be an insulator, semiconductor, or metal material, to effectively dissipate heat generated by the OLED device, thereby prolonging its service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If OLED device operates at higher brightness and larger size, then display performance is improved, but heat generation increases leading to shortened service life
Solution Approach 1:
The patent introduces a heat-dissipating layer as an intermediary component between the OLED device and the encapsulating layer. This layer acts as a mediator to transfer and dissipate heat away from the OLED device, allowing high brightness operation without compromising service life. The heat-dissipating layer is specifically designed to conduct heat away while maintaining the encapsulation integrity.
2Power
If OLED device operates at higher brightness and larger size, then display performance is improved, but excessive heat is generated
Solution Approach 1:
The patent converts the harmful heat generation into a manageable thermal management issue by introducing a dedicated heat-dissipating layer. This layer transforms the problematic heat into a controllable thermal flow that can be directed away from the OLED device, effectively converting a harmful byproduct into a manageable aspect of device operation.
3Temperature
If heat-dissipating layer is added to OLED substrate, then heat dissipation is improved, but device structure becomes more complex
Solution Approach 1:
The patent segments the OLED substrate structure by introducing a distinct heat-dissipating layer as a separate functional component. This segmentation allows the thermal management function to be independently optimized and integrated into the existing substrate architecture, adding heat dissipation capability without fundamentally redesigning the entire device structure.
