Abstract
A source driver comprising a frame memory, a first line buffer, and a second line buffer. The frame memory stores bits of pixel values of an image. The first line buffer then sequentially latches the bits of the pixel values from the frame memory with a first address index. The second line buffer then sequentially latch the bits of the pixel values from the first line buffer with a second address index, which is different from the first address index, and writes the bits of the pixel values back to the frame memory, such that the image is scrolled. The present invention also provides a method of refreshing the frame memory in a source driver.
