Shift Register Unit With Shared Blanking for Scan and Sense Signals

The patent combines the control functions for scan and sense driving signals into a single shared blanking control circuit. This circuit uses one set of control nodes (first and second control nodes) to manage both signal types, eliminating the need for separate control circuits. The shared circuit generates control signals for both scan and sense outputs using common transistors and capacitors, thereby reducing overall circuit complexity while maintaining the ability to produce signals with different periods and pulse widths through selective activation and timing control.

The blanking control circuit is designed with multi-functionality to handle both scan and sense driving signals. The control nodes and associated transistors serve dual purposes: they control the scan output during scan periods and the sense output during sense periods. This universal control mechanism allows a single circuit structure to perform multiple functions that would traditionally require separate dedicated circuits, thus reducing the total component count while preserving signal differentiation capabilities.

The patent employs dynamic control mechanisms where the single blanking control circuit adaptively changes its operation mode based on timing signals. The control nodes dynamically switch between controlling scan output and sense output depending on the signal period requirements. This dynamic behavior allows the simplified circuit to maintain high adaptability in managing multiple node levels for different signal types without requiring additional static circuit elements, thereby reducing manufacturing cost while preserving functional versatility.

The circuit utilizes parameter changes in timing and control signal characteristics to differentiate between scan and sense driving signals. By varying the timing parameters and control signal levels dynamically, the simplified circuit structure achieves the ability to manage multiple node levels for different signal periods. This parameter-based control approach eliminates the need for complex structural modifications, reducing transistor count and manufacturing cost while maintaining the required adaptability for different signal types.
