Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional gate driving circuits use fixed cascade connection of shift registers, then the circuit structure is simple, but the display resolution control flexibility is poor
Solution Approach 1:
The patent implements dynamic reconfiguration of shift register connections through mode control circuits that can switch between cascade and parallel connections based on control signals. This allows the gate driving circuit to adapt its resolution control flexibility dynamically while maintaining a relatively simple base circuit structure.
Solution Approach 2:
The mode control circuits enable the same shift register units to serve multiple functions by switching between cascade connection (for high resolution) and parallel connection (for low resolution). This multi-functionality resolves the contradiction by allowing one circuit structure to achieve both simplicity and adaptability across different operating modes.
2Measurement precision
If shift register units are connected in cascade for high resolution, then the display resolution is high, but the scanning time increases
Solution Approach 1:
The system dynamically switches between cascade and parallel connection modes depending on the required resolution and timing requirements. When high resolution is needed, cascade connection is used; when scanning speed is prioritized, parallel connection is activated, thus resolving the time-resolution tradeoff.
Solution Approach 2:
The invention changes the connection configuration parameter of shift register units based on operational requirements. By adjusting the connection mode (cascade or parallel) as a controllable parameter, the system can optimize between resolution and scanning time for different display scenarios.
3Speed
If shift register units are connected in parallel for fast scanning, then the scanning speed is fast, but the display resolution decreases
Solution Approach 1:
The mode control circuits enable shift register units to function in both parallel and cascade configurations, allowing the same hardware to achieve fast scanning when needed while maintaining the capability for high resolution when required, thus resolving the speed-resolution contradiction.
