Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If data lines are vertically separated in a central portion of the display panel to secure sufficient charging time, then the charging time for data signal is improved, but the display panel becomes vulnerable to static electricity and cannot discharge efficiently
Solution Approach 1:
The invention divides the data line structure into separate upper and lower data lines that are vertically separated in the central portion of the display panel. This segmentation allows each data line to be independently routed and connected to dedicated ESD circuits, enabling efficient electrostatic discharge while maintaining sufficient charging time for data signals.
Solution Approach 2:
The invention introduces ESD circuits as intermediary components that are electrically connected to both the upper and lower data lines. These ESD circuits act as mediators that provide a dedicated path for electrostatic discharge, resolving the vulnerability to static electricity without interfering with the normal data signal transmission and charging functions.
2Measurement precision
If data lines are vertically separated to achieve high-resolution display, then display resolution is improved, but electrostatic discharge efficiency deteriorates
Solution Approach 1:
The vertical separation of data lines into upper and lower segments enables high-resolution display by allowing independent routing and reduced interference. The invention complements this segmentation by providing separate ESD connection paths for each data line segment, ensuring that the resolution improvement does not come at the cost of electrostatic discharge efficiency.
Solution Approach 2:
The invention applies local quality by positioning ESD circuits specifically at the central portion of the display panel where the data lines are vertically separated. This localized approach ensures that electrostatic discharge is handled efficiently at the critical separation points without affecting the overall display resolution and performance.
3Reliability
If ESD circuit is added to the central portion of the display panel, then static electricity resistance is improved, but device complexity increases
Solution Approach 1:
The ESD circuits are designed to serve multiple functions: they provide electrostatic discharge paths for both upper and lower data lines, maintain signal integrity, and do not interfere with normal display operations. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while improving static electricity resistance.
Solution Approach 2:
The ESD circuits are integrated into the existing data line structure in such a way that they automatically provide electrostatic discharge functionality without requiring additional control circuits or complex management systems. The circuits operate autonomously to discharge static electricity, reducing the overall system complexity.
