Cushion Layer with Grounded Metal for Display Shock and Static Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in managing the increased area occupied by displays in electronic devices, particularly in preventing damage from external shocks and reducing the occurrence of greenish phenomena due to static electricity.
Innovation Solution
The display apparatus incorporates a cushion layer with a grounded metal material, specifically a copper material, that protrudes outward from the first cushion layer portion and is spaced apart from the cover window portion, thereby reducing the risk of static electricity-induced damage and enhancing shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cushion layer with grounded metal material is added under the display panel, then the protection against static electricity and shock absorption is improved, but the device complexity and layer structure become more complex
Solution Approach 1:
The cushion layer is segmented into two distinct portions: a first cushion layer portion that overlaps with the protective film for shock absorption, and a second cushion layer portion containing grounded metal material for static electricity protection. This segmentation allows each portion to perform its specific function independently, resolving the contradiction by organizing complexity into functional modules.
Solution Approach 2:
Different regions of the cushion layer are assigned different materials and functions: the first portion uses cushioning material for mechanical shock absorption, while the second portion uses grounded metal material for electrostatic discharge. This local differentiation optimizes each region for its specific purpose while maintaining overall system reliability.
2Area of moving object
If the display area is increased in electronic devices, then the visual information display capability is improved, but the vulnerability to external shocks and static electricity damage increases
Solution Approach 1:
The cushion layer is installed beforehand under the display panel to provide preemptive protection against external shocks and static electricity. The grounded metal material in the second cushion layer portion is pre-positioned to intercept and dissipate static charges before they can damage the display, while the first cushion layer portion is ready to absorb mechanical shocks.
Solution Approach 2:
The cushion layer acts as an intermediary protective barrier between the display panel and external harmful factors. The grounded metal material serves as a mediator that safely channels static electricity away from the display, while the cushioning material mediates mechanical shock absorption, protecting the display area from damage.
