ABSTRACT:
A novel method for asynchronously driving a display device including a plurality of pixels arranged in a plurality of columns and a plurality of rows includes the steps of receiving a first multi-bit data word indicative of a first grayscale value to be displayed on a pixel of a first row of the display, defining a first time period during which an electrical signal corresponding to the first grayscale value can be asserted on the pixel of said first row, receiving a second multi-bit data word indicative of a second grayscale value to be displayed on a pixel of a second row of the display, and defining a second time period that is temporally offset from the first time period during which an electrical signal corresponding to the second grayscale value can be asserted on the pixel of said second row. A novel display driver for performing the methods of the present invention is also disclosed.
