Engineering Contradiction Analysis
1Ease of operation
If traditional passive row-column scanning control method is used, then the LED array substrate can be controlled, but the control complexity increases and flickering occurs due to discontinuous light emission
Solution Approach 1:
The patent integrates the driver circuit directly on the LED array substrate, merging the control function with the display function. This integration eliminates the need for external driver circuits and enables continuous light emission by maintaining constant current supply to LEDs, thereby reducing control complexity and preventing flickering simultaneously.
Solution Approach 2:
The driver circuit is designed to be self-contained on the LED array substrate, where the circuit automatically manages current distribution to LED groups without requiring complex external control signals. The circuit autonomously maintains continuous operation by detecting and responding to current requirements, reducing the need for complex scanning control and ensuring continuous light emission.
2Productivity
If traditional driver circuit configuration is used, then LED array can be driven, but the number of driver circuits increases and external circuitry becomes complex
Solution Approach 1:
The driver circuit is integrated directly on the LED array substrate, merging previously separate components into a single unified structure. This integration dramatically reduces the number of external driver circuits needed and simplifies external circuitry, as the substrate itself now contains the necessary control functionality.
Solution Approach 2:
The integrated driver circuit on the LED array substrate performs multiple functions: it controls current distribution to multiple LED groups, manages timing sequences, and ensures continuous operation. This multi-functional design eliminates the need for multiple specialized driver circuits and complex external circuitry.
