Patent ID: 7446760

Claim:
A display device, comprising: (a) a pixels array including a plurality of pixels arranged in a form of a matrix; (b) a data driver for supplying a tone voltage corresponding to display data to the pixels; (c) a scan driver for selecting pixels of at least one row to which the tone voltage is to be supplied; and (d) a control circuit for controlling the data driver and the scan driver; wherein: (e) the control circuit outputs a first clock signal and the display data to the data driver; (f) the control circuit outputs to the scan driver a second clock signal, the second clock signal synchronized with the first clock signal and providing a two clock period of a first clock at every n signal creation, by way of not being created every n (n>2) signal creation thereof and outputs a scanning start signal generated a plurality of times during one frame period; and (g) the control circuit outputs to the data driver blanking data other than the display data in place of the display data during a period from the first clock signal of a first creation to a first clock signal of the second creation of the two clock signal period at every n signal creation; (h) the data driver, in accordance with the first clock signal, sequentially supplies tone voltage corresponding to the display data received from the control circuit and tone voltage in accordance with the blanking data received in place of the display data from the control circuit, to the pixels; (i) the scan driver, in accordance with the second clock signal, sequentially shifts pixel rows to be selected, and during the period from the first clock signal of the first creation to the first clock signal of the second creation of the two clock signal at every n signal creation, in addition to pixel rows being sequentially shifted, for selecting the other plurality of pixel rows separated from the pixel rows being sequentially shifted by a plurality of rows; and (j) the scan driver, in accordance with the scanning start signal, further repeats a selecting operation of the pixel rows sequentially shifted in accordance with the second clock signal and a selecting operation of the other plurality of pixel rows.
