Additional application of voltage during a write sequence
First Claim
1. A method of scanning a display during a first update, the method comprising:
- applying a first voltage to a first sub-pixel;
applying a second voltage to a second sub-pixel;
applying a third voltage to a third sub-pixel, the third sub-pixel being adjacent to the first sub-pixel and second sub-pixel, wherein a magnitude of the third voltage is a target voltage reached by overdriving the third sub-pixel to an overdrive voltage and stopping the overdriving when the magnitude of the third voltage is approximately equal to a magnitude of the target voltage for the third sub-pixel, a magnitude of the overdrive voltage being greater than the magnitude of the target voltage for the third sub-pixel;
applying a fourth voltage to the first sub-pixel after the application of the third voltage, the fourth voltage having a same polarity as the first voltage; and
applying a fifth voltage to the second sub-pixel after the application of the third voltage, the fifth voltage having a same polarity as the second voltage.

Abstract
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.
