    • A display device including: a display panel; and a signal controller which controls signals for driving the display panel, where the signal controller includes a representative value generator which sequentially operates a portion of image data of one frame, where the representative value generator moves a last position digit into another position digit of the portion of the image data and generates a representative value representing a portion of a frame image corresponding to the portion of the image data; a storage portion which stores the representative value therein; and a comparator which compares the representative values of present and prior frames to determine whether the portion of the frame image is a still image or a motion picture, and the signal controller controls the signals for driving the display panel such that a driving frequency for the still image is lower than a driving frequency for the motion picture.
    • 一种显示装置,包括:显示面板; 以及信号控制器,其控制用于驱动显示面板的信号,其中信号控制器包括代表值发生器,其顺序地操作一帧的图像数据的一部分,其中代表值发生器将最后位置数字移动到另一位置数位 并且生成表示对应于图像数据的一部分的帧图像的一部分的代表值; 在其中存储代表值的存储部分; 以及比较器,其比较当前帧和现有帧的代表值,以确定帧图像的部分是静止图像还是运动图像,并且信号控制器控制用于驱动显示面板的信号,使得用于 静止图像低于运动图像的驱动频率。
