Display Controller Timing Synchronization Feedback

The patent implements a feedback mechanism where each display controller detects synchronizing information from other displays and adjusts its timing control signals accordingly. The control circuit receives synchronizing information from multiple displays, compares timing parameters, and generates adjusted timing control signals to maintain synchronization across all displays, thereby resolving the timing synchronization issue in multi-display systems.

The patent replaces manual or mechanical timing adjustment mechanisms with an automated electronic feedback system. The control circuit electronically detects synchronizing information, processes timing comparisons, and automatically adjusts timing control signals without mechanical intervention, enabling precise synchronization across multiple displays through electronic control rather than mechanical means.

The patent merges the timing control functions across multiple independent display controllers into a coordinated system. Each control circuit generates timing control signals independently but integrates synchronizing information from other displays, effectively combining their operations to achieve synchronized timing alignment across all displays while maintaining relatively simple individual controller structures.

The control circuit is designed with multi-functionality, serving both its primary function of generating timing control signals for its own display and the additional function of detecting synchronizing information from other displays and adjusting its timing signals accordingly. This universal design enables timing alignment across multiple displays without requiring separate dedicated synchronization hardware for each display.
