Scanning orders in inversion schemes of displays

An apparatus comprising:

• a display screen including a plurality of sub-pixels including one or more target sub-pixels, one or more first sub-pixels, and one or more second sub-pixels, the one or more target sub-pixels being in between and adjacent to each of the one or more first sub-pixels and the one or more second sub-pixels;
• and
• a scanning system that scans the plurality of sub-pixels to update the sub-pixels, including
• updating the one or more target sub-pixels by applying a target voltage to the one or more target sub-pixels,
• updating, after the update of the one or more target sub-pixels, one or more first sub-pixels by applying a first voltage to the one or more first sub-pixels, wherein the application of the first voltage changes a voltage polarity of the one or more first sub-pixels in one of a positive direction and a negative direction and the application of the first voltage causes a first brightness change to the one or more target sub-pixels, and
• updating, after the update of the one or more first sub-pixels, one or more second sub-pixels by applying a second voltage to the one or more second sub-pixels, wherein the application of the second voltage changes a voltage polarity of the one or more second sub-pixels in an opposite direction as the change in voltage polarity of the one or more first sub-pixels and the application of the second voltage causes a second brightness change to the one or more target sub-pixels, the second brightness change offsetting the first brightness change.

A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a computing device, cause the device to perform a method of updating an image displayed by a display screen in a first image frame, the display screen including a plurality of sub-pixels, the method comprising:

• updating one or more target sub-pixels by applying a target voltage to the one or more target sub-pixels;
• updating, after the update of the one or more target sub-pixels, one or more first sub-pixels by applying a first voltage to the one or more first sub-pixels, the one or more first sub-pixels being adjacent to the one or more target sub-pixels, wherein the application of the first voltage changes of a voltage polarity of the one or more first sub-pixels in one of a positive direction and a negative direction and the application of the first voltage causes a first brightness change to the one or more target sub-pixels;
• and
• updating, after the update of the one or more first sub-pixels, one or more second sub-pixels by applying a second voltage to one or more second sub-pixels, the one or more second sub-pixels being adjacent to the one or more target sub-pixels, wherein the application of the second voltage changes a voltage polarity of the one or more second sub-pixels in an opposite direction as the change in voltage polarity of the one or more first sub-pixels and the application of the second voltage causes a second brightness change to the one or more target sub-pixels, the second brightness change equal to or less than the first brightness change.
