GOA Driving Circuit Power Reduction via Blank Screen Timer Shutdown

The patent applies the dynamics principle by making the operation state of the timer and frequency divider changeable rather than fixed. The controller dynamically adjusts their operation based on the display circuit's state: keeping them operating during startup to ensure timing reliability, and stopping them during normal operation to reduce power consumption. This dynamic state transition resolves the contradiction between maintaining reliability and reducing energy use.

The patent implements periodic action by having the timer and frequency divider operate only during specific periods (startup phase) and remain inactive during other periods (normal operation). The controller periodically activates these components when needed for timing functions and deactivates them when not needed, creating a periodic on-off pattern that reduces overall power consumption while maintaining necessary timing functionality during critical periods.

The patent applies the extraction principle by separating the timing control function from continuous operation. The controller extracts the timer and frequency divider from the continuously operating components, activating them only when needed for startup timing control. This extraction allows the timing function to be maintained during startup while preventing these components from operating continuously, thereby reducing power consumption and extending device service life.

The patent implements discarding and recovering by temporarily deactivating the timer and frequency divider after they have completed their timing function during startup. The components are discarded (stopped) during normal operation when their function is not needed, and can be recovered (reactivated) if timing control is needed again. This cyclical activation and deactivation pattern reduces cumulative power consumption while preserving the timing control capability when required.
