    摘要: In a display device capable of low power and multi-color displaying without raising a frame rate due to increase of display gradations in number by combining a gradation representation through a FRC and a gradation representation system using a pulse width modulation or pulse height modulation method, the gradation representation is executed by a method of pulse width or pulse height modulation in one frame using lower significant N bits to a video signal of M bits, and the display of the gradations is performed by the FRC of the present invention using more significant M−N bits and further using 2M−N−1 frames, and thus the number of the frames required for FRC is reduced to decrease a frame frequency to thereby realize a gradation display with reduction of electric power and suppression of flickers.

    摘要: An image display device comprises a first storage device (4) for storing an image data, an image processor (8) for reducing the number of bits of the image data, a second storage device (10) for storing the image data after being processed, a display device (12) for displaying the image data after being processed, a driver (14) for driving the display device (12) and a controller (16) for controlling the operation of the driver (14). The controller (16) determines whether the image data stored in the first storage device (4) is dynamic or static, and, in the case of a static image, after storing the signals corresponding to one frame of the image data in the second storage device (10), operates only the second storage device (10), the driver (14) and the display device (12). Thereby, reduction of power consumption can be achieved while maintaining high image quality.
