Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face defects due to static electricity transfer, which can cause issues such as coupling defects and electrostatic current interference with wires.
Innovation Solution
Incorporating a protruding member on the lower surface of the cover window, made of conductive material, to prevent or minimize static electricity transfer to wires, while maintaining a specific distance from the cover layer to effectively manage static discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protruding member is added on the lower surface of the cover window to prevent static electricity transfer, then reliability is improved, but device complexity increases
Solution Approach 1:
A protruding member made of conductive material is introduced as an intermediary element between the cover window and the wires. This mediator provides a controlled path for static electricity discharge, preventing uncontrolled electrostatic discharge to the wires while maintaining structural simplicity.
Solution Approach 2:
The harmful static electricity is extracted and redirected through the protruding member to a safe discharge path. By separating the static electricity management function into a dedicated protruding structure, the main display structure remains simple while reliability is improved.
2Reliability
If the protruding member is positioned close to the cover layer, then static electricity control is improved, but manufacturing precision requirements increase
Solution Approach 1:
The protruding member is positioned at a specific location on the lower surface of the cover window, away from the display panel area. This localized positioning provides effective static electricity control in the critical area while maintaining reasonable manufacturing tolerances for overall assembly.
