Dual-Screen LCD Panel Synchronization via Liquid Crystal Response Delay

The patent applies preliminary action by delaying the driving signal to the first display screen before the liquid crystal response duration difference causes display artifacts. The controller calculates the response duration difference and introduces a time delay to the first screen's driving signal, ensuring both screens reach their target liquid crystal rotation angles simultaneously. This preliminary timing adjustment prevents the display effect deterioration while maintaining the contrast improvement from dual-screen dimming functionality.

The controller performs preliminary calculation of the liquid crystal response duration difference between the two display screens and introduces a compensatory time delay to the first screen's driving signal. This delay is precisely calculated to match the response duration difference, ensuring that both screens' liquid crystals reach their target angles simultaneously. The preliminary timing adjustment maintains optimal response time while synchronizing display output.

The controller implements feedback by continuously monitoring the liquid crystal response durations of both display screens and dynamically adjusting the driving signal timing accordingly. The system calculates the response duration difference and applies the appropriate delay to the first screen's driving signal, creating a closed-loop control system that automatically compensates for hardware variations. This feedback mechanism synchronizes the liquid crystal rotation angles while managing control complexity through automated calculation and adjustment.
