Engineering Contradiction Analysis
1Loss of energy
If dynamic variable frequency technology is applied to the entire display panel, then power consumption is reduced, but the ability to realize frequency changes in local parts of the display area is lost
Solution Approach 1:
The display panel is divided into multiple independent display areas, each with its own pixel circuits connected to different driving circuits. This segmentation allows each area to operate at different frequencies independently, enabling local frequency adjustment while maintaining overall power efficiency.
Solution Approach 2:
The patent implements dynamic frequency adjustment by coupling pixel circuits to multiple driving circuits that can provide different scanning frequencies. This dynamic configuration allows the display panel to adaptively change frequencies in different areas based on real-time display needs, combining power savings with operational flexibility.
2Device complexity
If a single driving circuit is used for the entire display panel, then device complexity is reduced, but the ability to operate different areas at different frequencies is lost
Solution Approach 1:
The display panel is divided into multiple independent display areas, each with its own pixel circuits connected to different driving circuits. This segmentation allows each area to operate at different frequencies independently, enabling local frequency adjustment while maintaining overall power efficiency.
Solution Approach 2:
The patent employs multiple driving circuits that can serve different display areas with different frequency requirements. Each driving circuit is designed with multi-functionality to handle various scanning frequencies, allowing the system to maintain lower complexity while achieving versatile frequency adjustment capabilities across different regions.
