Engineering Contradiction Analysis
1Productivity
If electronic components are increased in capacity and integration to achieve high performance, then display device performance is improved, but heat generation increases causing potential failure or malfunction
Solution Approach 1:
The patent applies this principle by using the heat-conducting particles and heat dissipation layers to convert the harmful heat generated by electronic components into a manageable thermal flow that can be directed and dissipated efficiently through the functional layer structure, preventing overheating while maintaining high-performance components
Solution Approach 2:
The functional layer acts as an intermediary between the electronic components and the display panel, with heat-conducting particles and heat dissipation layers serving as intermediate structures that facilitate thermal management without interfering with the electronic components' high-performance operation
2Object-generated harmful factors
If heat dissipation structures are added to dissipate heat, then heat dissipation capability is improved, but device complexity increases
Solution Approach 1:
The functional layer is designed to perform multiple functions simultaneously: the heat-conducting particles provide thermal conduction, the adhesive layer provides bonding, and the heat dissipation layers provide both thermal management and electromagnetic shielding, thereby reducing the need for separate dedicated components and simplifying the overall device structure
Solution Approach 2:
The patent uses composite materials in the functional layer, combining heat-conducting particles with adhesive materials and integrating heat dissipation layers with electromagnetic shield materials, creating multi-functional composite structures that achieve heat dissipation without proportionally increasing device complexity
