Pre-charging of sub-pixels
First Claim
1. 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 including a first sub-pixel with a first pixel electrode and a second sub-pixel with a second pixel electrode, the second sub-pixel being disposed adjacent to the first sub-pixel, the method comprising:
- applying a first voltage to the second pixel electrode;
updating the first pixel electrode to a first target voltage value corresponding to a first luminance of the first sub-pixel by applying a second voltage to the first pixel electrode, the second voltage being applied after the application of the first voltage;
updating the second pixel electrode to a second target voltage value corresponding to a second luminance of the second sub-pixel by applying a third voltage to the second pixel electrode, the third voltage being applied after the application of the second voltage; and
applying the first voltage to a third pixel electrode of a third sub-pixel concurrently with the application of the first voltage to the second pixel electrode.

Abstract
Pre-charging display screen sub-pixels, such as aggressor sub-pixels, prior to the application of a target data voltage to the aggressor sub-pixels is provided. In some examples, a target voltage of a sub-pixel in a previous row in the scanning order of the display can be used to pre-charge sub-pixels. The row of sub-pixels to be pre-charged can be switched on during the updating of another row of sub-pixels. In this way, for example, target voltages applied to data lines while an update row is connected to the data lines, e.g., to update the update row, can be applied to the row to be pre-charged as well.
