Gate Driver Charge Sharing Module Reduces Power Consumption

The patent converts the harmful coupling effect into a beneficial charge transfer mechanism. By intentionally allowing parasitic capacitors to couple during the backward edge of gate signals, the invention recovers charge that would otherwise be lost, and redirects it to adjacent pixels. This transforms the harmful coupling into a useful charge recycling mechanism that reduces power consumption while maintaining image quality.

The patent recovers charge that would normally be discarded during the operation of the gate driver. By capturing the charge transferred through parasitic capacitors during signal transitions and redirecting it to useful purposes (charging adjacent pixels or returning it to the voltage source), the system recovers energy that would otherwise be wasted, thereby reducing overall power consumption.

The patent applies preliminary action by proactively managing the charge coupling that occurs during fast gate signal transitions. Before abnormal image contents can be generated, the invention anticipates the charge transfer through parasitic capacitors and deliberately controls this process by adjusting signal waveforms and timing. This preliminary control prevents the harmful effects while maintaining fast operation speed.

The patent converts the harmful parasitic coupling effect into a beneficial mechanism by intentionally utilizing the charge transfer that occurs during fast transitions. Instead of trying to eliminate the coupling, the invention harnesses it to transfer charge to adjacent pixels or recycle it, thereby maintaining high-speed operation while preventing abnormal image contents.

The patent applies universality by designing control circuits that perform multiple functions simultaneously. The same control logic that adjusts gate signal waveforms also manages charge recycling and mitigates coupling effects across multiple pixels. By making the control circuit multi-functional, the invention avoids adding separate dedicated circuits for each function, thereby improving image quality without proportionally increasing device complexity.

The patent merges multiple functions into unified control mechanisms. Instead of having separate circuits for waveform adjustment, charge management, and coupling mitigation, the invention combines these functions into integrated control logic that handles all tasks through coordinated operation of shared circuit elements, thereby reducing overall device complexity.
