Abstract
Methods of writing display data to MEMS display elements are configured to minimize charge buildup and differential aging. Simultaneous to writing rows of image data, a pre-write operation is performed on a next row. The pre-write operation writes either image data or the inverse of the image data to the next row. In some embodiments, the selection between writing image data and writing inverse image data is performed in a random or pseudo-random manner.
