Abstract
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reducing artifacts in an image generated by a display device. In one aspect, data is written to a display and a position of display elements is maintained based on the application of a bias voltage pattern. The bias voltage pattern includes alternating polarities along one dimension in a pattern having a first frequency spectrum, and alternating polarities along a second dimension in a pattern having a second frequency spectrum that is different than the first frequency spectrum. At least one of the first and second frequency spectrums may include a plurality of frequency components.
