Waterproof Structure for Display Device with Groove Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof structures for display devices suffer from poor performance due to gaps at right-angle connecting locations, leading to moisture permeation and potential short circuits, and are complicated and costly to produce.
Innovation Solution
A waterproof structure featuring a back cover with a peripheral part, stop part, and groove, where the peripheral part is taller than the stop part, and includes partition pieces and a waterproof member with inclined or polygonal surfaces to prevent moisture ingress and facilitate easy assembly and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof strips are installed at the periphery of the display device, then waterproof protection is provided, but gaps are easily formed at right-angle connecting locations leading to poor waterproof performance
Solution Approach 1:
The waterproof structure is divided into multiple waterproof components (first waterproof component on the back cover, second waterproof component on the front frame) that are separately installed and then connected. This segmentation allows each component to be independently manufactured and positioned, reducing the formation of gaps at connecting locations while maintaining overall waterproof performance.
2Reliability
If additional waterproof structures are installed at proper locations to improve waterproof performance, then waterproof protection is enhanced, but production becomes more complicated and costly
Solution Approach 1:
The first waterproof component is integrated with the back cover as a single assembly, and the second waterproof component is integrated with the front frame. This merging eliminates the need for separate installation steps for additional waterproof structures, simplifying production while maintaining enhanced waterproof performance through the coordinated arrangement of the two components.
3Reliability
If waterproof strips are used to protect the display device, then initial waterproof protection is provided, but the waterproof strip deteriorates and fatigues over time allowing water permeation
Solution Approach 1:
Different waterproof components are used at different locations: the first waterproof component (with better durability characteristics) is positioned at the back cover where it can provide long-term protection, while the second waterproof component is positioned at the front frame. This local differentiation ensures that critical areas have components with appropriate durability for their specific service conditions, extending overall service life.

AI summary
A waterproof structure for use in display device includes a back cover (100), a display module (200) and a waterproof member (300). The back cover (100) includes a peripheral part of back cover (110), a stop part (120) connected to the peripheral part of back cover (110), and a groove (130) defined between the peripheral part of back cover (110) and the stop part (120), wherein the height of the peripheral part of back cover (110) is greater than the height of the stop part (120). The display module (200) is disposed on the back cover (100). The waterproof member (300) is disposed between the display module (200) and the stop part (120). Accordingly, the speed of moisture permeating into the display device can be buffered so as to prolong the service life.
