Waterproof Coating on Display Side Walls for Moisture Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The display module in terminal equipment, such as smartphones and tablets, has poor waterproof performance, often affected by moisture like sweat, which impacts the display function and user experience.
Innovation Solution
A waterproof coating is applied to at least one side wall of the display module body, specifically using a cross-linked polymer glue based on Silane-terminated polyether, to enhance the waterproof performance and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof coating is applied to the display module body, then waterproof performance is improved, but the device complexity increases
Solution Approach 1:
A waterproof coating layer is introduced as an intermediary between the display module body and the external environment. This coating layer acts as a barrier that prevents moisture from penetrating into the display module, thereby improving waterproof performance without fundamentally changing the display module's internal structure.
Solution Approach 2:
The patent employs composite material structure by combining the display module body with a waterproof coating layer. The waterproof coating is formed using cross-linked polymer glue based on Silane-terminated polyether, creating a composite structure that integrates the functional properties of both the display module and the waterproof material.
2Reliability
If a waterproof coating is applied to the display module body, then waterproof performance is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The waterproof coating is applied as a preliminary protective layer on the display module body before final assembly. By pre-applying the waterproof coating to the display module body, the manufacturing process ensures that waterproofing is integrated early in the production sequence, preventing moisture ingress before it can affect internal components.
3Object-affected harmful factors
If the display module is made waterproof, then resistance to moisture is improved, but the structural complexity increases
Solution Approach 1:
The waterproof coating is implemented as a thin film layer that conforms to the contours of the display module body. This thin film approach provides effective moisture barrier protection while maintaining the original structural form and dimensions of the display module, avoiding the need for bulky waterproofing structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The waterproof coating effectively prevents moisture from affecting the display function, improving the user experience by enhancing the waterproof performance of the display module without occupying excessive space.
Implementation Method 1
A waterproof coating is disposed on at least one side wall of the display body
