Display Panel Protective Layer for Impact and Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in providing reliable protection for display panels against external impacts and heat dissipation while maintaining structural integrity and efficiency in manufacturing processes.
Innovation Solution
The electronic device incorporates a display panel with a first protective layer composed of a curable resin, which has a lower contact angle with water and includes a heat dissipation material, and is directly disposed on specific regions of the display panel, along with a heat dissipation layer beneath, to enhance protection and thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective layer is added to protect the display panel from external impacts and heat, then the protection capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (protection from impact, heat dissipation, and adhesion) into a single protective layer structure. This layer includes a first region with a protective layer having a first contact angle and a second region with a protective layer having a second contact angle greater than the first, allowing one layer to perform multiple functions that previously required separate components.
Solution Approach 2:
The protective layer is designed with spatially varying contact angles: the first region (overlapping the display panel) has a smaller contact angle for better adhesion and protection, while the second region (overlapping the electronic module) has a larger contact angle for optimized thermal management and module attachment. This local differentiation allows each region to be optimized for its specific function.
2Reliability
If a stacked structure of multiple functional layers is used to protect the display panel, then the protection function is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent integrates heat dissipation materials, protective functions, and adhesion properties into a single protective layer rather than using separate stacked layers. The protective layer contains heat dissipation materials dispersed within the resin matrix, eliminating the need for separate heat dissipation layers and simplifying the manufacturing process.
Solution Approach 2:
The protective layer is formed as a composite material consisting of a resin matrix with dispersed heat dissipation materials (such as metal particles, ceramic particles, or carbon-based materials). This composite structure provides both protective and thermal management functions within a single layer, reducing manufacturing complexity compared to separate functional layers.
3Ease of manufacture
If a single-layered protective layer with integrated functions is used, then the manufacturing process is simplified, but the protection reliability may be compromised
Solution Approach 1:
The single protective layer is designed with spatially varying properties: the first region has a smaller contact angle (30°-60°) optimized for strong adhesion to the display panel and impact protection, while the second region has a larger contact angle (60°-90°) optimized for thermal management and electronic module attachment. This local differentiation maintains protection reliability while using a single layer.
Solution Approach 2:
The protective layer uses a composite material structure with heat dissipation materials (metal particles, ceramic particles, or carbon-based materials) dispersed in the resin matrix. This composite approach enables the single layer to provide both mechanical protection and thermal management functions that previously required multiple separate layers, maintaining reliability while simplifying manufacturing.

AI summary
An electronic device includes: a display panel including a first region, and a second region adjacent to the first region; a protective layer overlapping the first region and disposed under the display panel; and an electronic module overlapping the second region and disposed below the display panel. A lower surface of the display panel includes a first lower surface overlapping the first region and a second lower surface overlapping the second region, and a contact angle between the first lower surface and water is smaller than a contact angle between the second lower surface and water.
