A matrix-type display device has a matrix display panel, a frame memory, and a graphics memory. Input image data are temporarily buffered in the graphics memory, then transferred to the frame memory and read out to drive the matrix display panel. Readout from the frame memory is cyclic, and is synchronized with a frame synchronization signal. A synchronizing circuit also synchronizes the transfer of data from the graphics memory to the frame memory with the frame synchronization signal, so that each displayed frame is generated from a single frame of image data, and not from parts of two different frames. Moving images can therefore be reproduced faithfully. This matrix-type display device is useful in mobile information-terminal equipment, such as mobile telephone sets.
