Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies are prone to faults due to static electricity shocks, which can cause irreversible damage, and existing solutions often require removing anti-fingerprint coatings to mitigate this issue, leading to poor user experience.
Innovation Solution
Incorporating electrostatic dissipation layers in the display assembly, such as in the polarizer and heat dissipation film, to guide static electricity away from the display panel, thereby preventing accumulation and fault occurrence without removing the anti-fingerprint coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrostatic dissipation layer is added to the display assembly, then the anti-static capability is improved, but the device complexity increases
Solution Approach 1:
The electrostatic dissipation layer is merged with existing components of the display assembly, specifically integrated into the polarizer or heat dissipation film. This combination allows the anti-static function to be achieved without adding separate independent components, thereby improving reliability while minimizing increases in device complexity.
Solution Approach 2:
The electrostatic dissipation layer serves multiple functions: it provides anti-static protection by guiding static electricity away from the display panel, while simultaneously being integrated into components that perform their original functions (polarization or heat dissipation). This multi-functionality approach improves reliability without proportionally increasing device complexity.
2Reliability
If the anti-fingerprint coating is removed to prevent static electricity, then the anti-static capability is improved, but the user experience deteriorates
Solution Approach 1:
The solution segments the anti-static function from the anti-fingerprint coating function. Instead of removing the coating, a separate electrostatic dissipation layer is introduced that performs the anti-static function independently. This allows the anti-fingerprint coating to remain intact, preserving user experience while achieving anti-static protection.
Solution Approach 2:
The electrostatic dissipation layer acts as an intermediary component between the external environment and the display panel. It intercepts and guides static electricity away before it can reach sensitive components, while allowing the anti-fingerprint coating to remain on the outer surface for maintaining user experience.
