Abstract:
1. A method of scanning a display, the display including a plurality of lines of sub-pixels, each sub-pixel being associated with one of a plurality of data lines, the method comprising: applying a first voltage to a common electrode of the sub-pixels; scanning a first line of sub-pixels while the first voltage is being applied to the common electrode, wherein scanning the first line includes connecting a first subset of the data lines to one or more voltage sources while remaining data lines are disconnected from the one or more voltage sources, applying data voltages to the first subset of data lines, disconnecting the first subset of data lines from the one or more voltage sources, connecting a second subset of the data lines to the one or more voltage sources, and applying data voltages to the second subset of data lines; applying, during a first time period after the scanning of the first line and before a scanning of a second line of sub-pixels, a second voltage to the common electrode, wherein the second voltage is different than the first voltage; connecting, during the first time period, the plurality of data lines to the one or more voltage sources, such that the data lines are connected to the one or more voltage sources concurrently with the second voltage being applied to the common electrode; applying, during the first time period, one or more fixed voltages to the data lines; and scanning the second line of sub-pixels while the second voltage is being applied to the common electrode, wherein scanning the second line includes connecting the first subset of the data lines to the one or more voltage sources while the remaining data lines are disconnected from the one or more voltage sources, applying data voltages to the first subset of data lines, disconnecting the first subset of data lines from the one or more voltage sources, connecting a second subset of the data lines to the one or more voltage sources, and applying data voltages to the second subset of data lines, wherein the one or more fixed voltages includes a mid-level gray voltage.
