Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panels face challenges in protecting lead wires from static electricity damage while minimizing the space occupied by the electrostatic discharge circuit.
Innovation Solution
The display panel incorporates a structure with barrier portions in the non-display area and an electrostatic discharge unit between these barriers, connected to the signal lines to discharge static electricity, thereby preventing damage and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrostatic discharge circuit is added to protect lead wires from static electricity, then the reliability of the display panel is improved, but the border space of the display panel increases
Solution Approach 1:
The electrostatic discharge unit is merged with the existing barrier portions in the non-display area. The barrier portions serve dual functions: both as structural barriers and as housing for the electrostatic discharge units, eliminating the need for separate dedicated space for ESD protection circuitry.
Solution Approach 2:
The barrier portions are designed to perform multiple functions simultaneously: they act as both physical barriers and as containers for electrostatic discharge units. This multi-functionality allows the same structural elements to provide both mechanical support and electrostatic protection without increasing overall border space.
2Area of moving object
If the electrostatic discharge circuit is placed in the non-display area, then the display area is preserved, but the arrangement of the circuit becomes complex
Solution Approach 1:
The non-display area is segmented into multiple barrier portions, with electrostatic discharge units selectively placed in specific segments (first and second barrier portions). This segmentation allows for systematic organization of ESD units without requiring complex routing across the entire non-display area.
Solution Approach 2:
Electrostatic discharge units are not uniformly distributed across all barrier portions but are strategically placed in specific locations (first and second barrier portions) where they are most needed. This localized placement simplifies the overall arrangement by focusing ESD protection only in critical areas rather than implementing it uniformly throughout.
