Abstract
A method for digital driving of an active matrix display with a predetermined frame rate is described. The display contains a plurality of pixels organized in a plurality of rows and a plurality of columns. The method includes representing each of the plurality of pixels of an image to be displayed within a frame by an n-bit digital image code. The method also includes dividing the image frame into sub-frames, which may be of substantially equal duration. Within each sub-frame, the method includes sequentially selecting at least one of the plurality of rows twice. Upon a first selection, a first digital code is written to the selected row and upon a second selection a second digital code is written to the selected row. There is a predetermined time delay between the second selection and the first selection. Digital driving circuitry is also described.
