Gate Driving Circuit Reset Signal Inversion for Display Power Reduction

The patent inverts the traditional reset signal transmission direction in the gate driving circuit. Instead of resetting gate driving units in sequential order from first to last stage, the reset signals are transmitted in reverse order where the last stage gate driving unit is reset first, then the second-to-last stage, and so on. This inverted reset sequence reduces the number of polarity changes required in the dot inversion manner, thereby reducing display power consumption while maintaining stable display output without flickering

The patent introduces dynamic control of reset signal timing through multiple control signals (first control signal and second control signal) that dynamically adjust the reset sequence of different gate driving units. The reset adjustment unit dynamically switches between different reset patterns based on these control signals, allowing the system to adaptively optimize power consumption while ensuring display stability under different operating conditions

The patent applies the inversion principle by reversing the reset signal transmission sequence through the cascaded gate driving units. By resetting the last stage first and proceeding backward to the first stage, the system reduces the frequency of polarity inversions required to maintain display output, thereby lowering power consumption while preserving display quality

The patent implements periodic reset actions with optimized timing through the reset adjustment unit. By controlling the periodic transmission of reset signals in the inverted sequence, the system maintains display output stability while minimizing the frequency of polarity changes, thus reducing power consumption associated with frequent switching
