Insulating Spacer for Display Static Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with metallic upper covers and liquid crystal cells are prone to malfunction due to direct contact, which can cause discharge from static electricity, leading to burnout or malfunction.
Innovation Solution
Incorporating an electrically insulating spacer between the conductive panel and the display, which supports the display away from the opening and electrically isolates it from the panel, thereby preventing static electricity discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid crystal cell is directly bonded to the frame body with double-sided tape, then the device structure is simple and easy to manufacture, but static electricity discharge can cause burnout or malfunction of the liquid crystal cell
Solution Approach 1:
A resin layer is introduced as an intermediary substance between the liquid crystal cell and the frame body. This resin layer serves dual purposes: it provides electrical insulation to prevent static electricity discharge while also functioning as an adhesive to bond the liquid crystal cell to the frame body, thereby maintaining ease of manufacture while improving reliability
Solution Approach 2:
The invention replaces the direct bonding method with a coating-based approach where a resin layer is applied to the frame body surface. This creates a protective interface that copies the bonding function while adding electrical insulation properties, preventing static electricity from reaching the liquid crystal cell
2Device complexity
If the metallic upper cover and liquid crystal cell are in direct contact, then the device structure is simplified, but static electricity discharge can cause burnout or malfunction
Solution Approach 1:
A resin layer is introduced as an intermediary between the metallic upper cover and the liquid crystal cell. This resin layer provides electrical insulation to block static electricity discharge while maintaining the structural simplicity of the device, thus reducing device complexity while protecting against harmful static electricity effects
