Abstract:
1. An image display device, comprising: pixels disposed at portions at which scanning lines and data lines intersect with each other; a scanning driving unit driving the scanning lines; a data driving unit driving the data lines; a driving frame frequency selecting unit generating a selecting signal including information on a driving frame frequency based upon a number of frames of image data supplied from an external system within a predetermined time period, wherein the external system does not supply the image data in the case in which current image data and previous image data are the same as each other; and a timing controlling unit controlling the scanning driving unit and the data driving unit according to the driving frame frequency included in the selecting signal, wherein the driving frame frequency selecting unit to generate a first selecting signal to drive the image display device at a first driving frame frequency corresponding to a relatively still image being displayed upon the number of frames of image data supplied from the external system within the predetermined period of time being less than a preset threshold, and the driving frame frequency selecting unit to generate a second selecting signal to drive the image display device at a second and higher driving frame frequency corresponding to a moving picture being displayed upon the number of frames of data supplied from the external system within the predetermined period of time being equal to or greater than the preset threshold.
