Signal Processing Circuit for Multi-Pulse GOA Driving

The patent combines multiple shift registers (first shift register and second shift register) into a single integrated circuit structure that can be implemented on the array substrate. This merging approach enables multi-pulse driving capability while avoiding the need for a separate gate driving chip, thus reducing the occupied space while maintaining the adaptability for multi-pulse gate line driving.

The patent introduces control signals (first control signal and second control signal) that dynamically switch the operating mode of the shift registers. By controlling the timing and sequence of these control signals, the circuit can dynamically generate multi-pulse outputs from the GOA structure, enabling both narrow bezel design and multi-pulse signal capability through dynamic signal manipulation rather than static circuit configuration.

The patent employs periodic control signals that are applied in specific sequences to the shift registers. The first control signal and second control signal are activated at different time periods, creating a periodic pattern of pulse outputs. This periodic action enables the generation of multiple pulses required for pixel compensation while maintaining a relatively simple circuit structure that can be integrated into the display panel.
