摘要:
With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce these visual artifacts by applying voltage to a data line more than once during the write sequence. Doing so can allow erroneous brightening or darkening caused by large voltage swings to be overwritten without causing additional large voltage swings on the data line.
