Pixel Driving Circuit Reset Scheme for Low-Frequency Flicker Reduction

The patent applies preliminary action by performing a reset operation on the driving transistor before the data writing phase in the writing frame. This reset operation initializes the transistor characteristics to a known state, ensuring consistent brightness across different frames. The reset phase is executed in advance of data writing, preventing the brightness inconsistency that causes flicker during low-frequency display.

The patent segments the display frame into distinct phases: a reset phase followed by a data writing phase. By dividing the frame into these separate functional segments, the circuit can systematically reset the driving transistor characteristics before writing data, ensuring brightness uniformity without excessively complicating the overall circuit operation. Each phase has a specific function that contributes to eliminating flicker.

The patent implements a control module that performs multiple functions: it generates control signals for resetting the driving transistor, manages the timing of the reset operation, and coordinates with the data writing process. By making this control module multi-functional, the patent achieves brightness uniformity without proportionally increasing device complexity, as a single module handles several critical tasks rather than requiring separate dedicated components for each function.
