Abstract:
1. A method of providing image data to source drivers for a display device comprising b*y rows and a*x columns of pixels, where b>a, the method comprising: receiving image data for b*y rows of pixels of the display device, the image data for each of the b*y rows of pixels including image data for each of the a*x columns of pixels of the display device; storing the image data for the b*y rows of pixels including image data for each of the a*x columns of pixels of the display device into a*y rows of memory cells including b*x columns of memory cells in a graphics memory device, wherein each of the a*y rows of memory cells in the graphic memory device stores image data for an entire one of the b*y rows of pixels of the display device, and further stores image data for x columns of each of (b−a) other rows of pixels of the display device; and sequentially supplying the image data for each of the b*y rows of pixels of the display device from the graphic memory device to the source drivers, where a, b, x and y are positive integers, wherein sequentially supplying the image data for each of the b*y rows of pixels the display device from the graphic memory device to the source drivers comprises: (a) supplying the image data for an ((a+j)*i+1) (b) supplying the image data for a next one of the b*y rows of pixels the display device, from a next one of the a*y rows of memory cells in the graphic memory device to the source drivers; (c) repeating step (b) until image data for a total of a rows of pixels of the display device have been supplied from the graphic memory device to the source drivers; (d) subsequent to steps (a) through (c), sequentially supplying to the source drivers image data for an ((a+n)*(i+1)) (e) repeating steps (a) through (d) for all i, where 0≦i≦(y−1), where i and j are positive integers.
