Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a terminal is provided on the liquid crystal panel to monitor the signal, then the signal can be monitored, but the number of connection terminals increases and the device configuration becomes complicated
Solution Approach 1:
The inspection electrode is integrated directly onto the flexible substrate, merging the monitoring function with the existing substrate structure. This eliminates the need for separate external terminals on the liquid crystal panel, thereby maintaining signal monitoring capability while simplifying the overall device configuration.
Solution Approach 2:
The inspection electrode acts as an intermediary element that bridges the integrated circuit and the external monitoring equipment. It provides a direct interface for signal inspection without requiring additional connection terminals on the liquid crystal panel, thus resolving the contradiction between monitoring capability and device complexity.
2Measurement precision
If a terminal is provided on the liquid crystal panel, then external signals can be monitored, but internal processing signals of the integrated circuit cannot be monitored
Solution Approach 1:
The inspection electrode is positioned to access specific internal signal lines within the integrated circuit area on the flexible substrate. This segmentation approach allows selective monitoring of internal processing signals that would otherwise be inaccessible through external terminals on the liquid crystal panel.
Solution Approach 2:
The inspection electrode extends from the flexible substrate surface into the signal processing area, creating a new dimensional access point for signal monitoring. This allows direct contact with internal circuit signals without requiring external terminals, thereby expanding the monitoring scope to include internal processing signals.
