Abstract
A method and an apparatus for operating an LED display are provided. The method includes: storing Nth scan line data in a line buffer; storing the Nth scan line data in a frame buffer; displaying the Nth scan line data stored in the line buffer; during the displaying of the Nth scan line data stored in the line buffer, storing (N+1)th scan line data in the line buffer; storing the (N+1)th scan line data in the frame buffer; displaying the (N+1)th scan line data stored in the line buffer; repeating the above steps until (N+M)th scan line data stored in the line buffer is displayed; and displaying scan line data stored in the frame buffer from the Nth scan line data to the (N+M)th scan line data.
