A flat-panel display device includes a matrix array of display pixels which respectively have memory elements, a vertical decoder which selectively designates row blocks of the display pixels, a horizontal decoder which selectively designates column blocks of the display pixels, a video RAM which stores image data respectively assigned to the memory elements, and a controller which controls the vertical and horizontal decoders to write the contents of the video RAM in units of blocks specified by row and column block addresses. The device further includes an interface which determines a rewriting range corresponding to at least one block of the display pixels including display pixels for part of the image data when the part is updated in the video RAM, and supplies to the controller the image data assigned to each block included in the rewriting range.
