提供一种能忠实地再生活动图像的移动信息终端装置用的矩阵型显示装置。矩阵型显示装置包括矩阵型显示板、帧存储器和图形存储器。输入图像数据，在图形存储器上临时被缓冲，而后传送给帧存储器，再为驱动矩阵显示板而被读出。从帧存储器的读出，是周期性的且由帧同步信号而被同步。在同步电路中，利用帧同步信号，使从图形存储器向帧存储器的数据传送同步，从而使得各被显示的帧是从图像数据的单个帧生成，而不是从两个不同帧的局部生成。由此，能忠实地再现图像的动作。这种矩阵型显示装置可利用于移动式的信息终端装置(如移动电话组合)。 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.
