Writing data to sub-pixels using different write sequences
First Claim
1. A method of scanning a display, the display including a plurality of display pixels that are each associated with a set of a plurality of data lines, comprising:
- electrically connecting each display pixel in a line of the display pixels to the associated set of data lines during an update of the line of display pixels, the line of display pixels including a first display pixel associated with a first set of data lines and a second display pixel associated with a second set of data lines;
sequentially applying voltages to the first set of data lines in a first sub-pixel color order write sequence of a plurality of write sequences of the data lines during the update of the line of display pixels; and
sequentially applying voltages to the second set of data lines in a second sub-pixel color order write sequence of the plurality of write sequences of the data lines, different than the first write sequence, during the update of the line of display pixels, and wherein the plurality of write sequences result in, after application of voltages to all of the plurality of display pixels in the display, each sub-pixel of the display, if shifted due to application of the voltages to adjacent sub-pixels during a corresponding write sequence of the plurality of write sequences, being shifted only in one direction common to all shifted sub-pixels.

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 persisting visual artifacts by offsetting their effects or by distributing their presence among different colored sub-pixels. In some embodiments, this may be accomplished by using different write sequences during the update of a row of pixels.
