Time-Divided Display-Touch Gate Driving with Narrower Touch Pulses

The gate driving circuit is designed with dynamic reconfigurability, allowing it to switch between display driving mode and touch sensing mode. The circuit can be selectively activated or deactivated based on the current operation mode, enabling flexible time-division multiplexing between display and touch functions without requiring separate dedicated circuits for each function.

The gate driving circuit is divided into multiple stages that can be independently controlled. By segmenting the circuit into display-driving stages and touch-sensing stages, the system can selectively activate only the necessary stages for the current operation, thereby securing sufficient scan output time for touch sensing while maintaining display functionality.

The gate driving circuit is activated in advance before the touch scan signal needs to be output. By pre-activating the circuit stages and preparing the signal path beforehand, the system can deliver a wider pulse width touch scan signal within the available time frame, thereby improving touch sensing performance without exceeding the total scan output time budget.

The gate driving circuit uses accelerated signal propagation techniques to quickly transition through the necessary stages. By rushing the signal through the circuit stages with optimized timing and reduced delays, the system can accommodate wider pulse widths for improved touch sensing while still completing the scan operation within the required time constraints.
