Claim Text:
1. A method of transferring image data for a display device assembly, which comprises a CPU memory; a display controller comprising two buffers, a memory controller and a look-up table; an image memory; and a display device; wherein new image data are transmitted from the CPU memory to the buffers as determined by the memory controller, which method comprises: (A) (i) accessing current and next image data from the image memory and comparing the two images, (B) during an idle time transferring image data from one buffer of the two buffers which is full to the image memory and simultaneously transferring image data from the CPU memory to another buffer of the two buffers, wherein the idle time is after voltages for a line of pixels have been sent to the display device and before waveforms of a next line of pixels are processed, wherein both steps A and B are completed within a line updating time period, and (C) repeating steps A and B in an alternating manner and step B is present only when one of the buffers is full.
