Patent ID: 7038651

Claim:
A display device comprising: a pixel array having a plurality of pixels which are arranged two-dimensionally along a first direction and a second direction which crosses the first direction; a plurality of first signal lines, which are juxtaposed along the second direction of the pixel array and transmit scanning signals which select a plurality of pixel rows consisting of respective groups formed of a plurality of pixel along the first direction; a plurality of second signal lines, which are juxtaposed along the first direction of the pixel array and supply display signals to the pixels included in pixel rows which are selected from a plurality of pixel rows in response to the scanning signals, the display signals determining respective display states of the pixels; a first driving circuit which outputs the scanning signals to a plurality of respective first signal lines; a second driving circuit which outputs the display signals to a plurality of respective second signal lines; a display control circuit which transmits a first clock signal which controls an output interval of the scanning signals to the first signal lines and a scanning starting signal which makes the display control circuit start the selection of the pixel rows over the pixel array in response to the first clock signal to the first driving circuit, and transmits the second clock signal which controls an output interval of the display signals to the second driving circuit; and a clock generating circuit which generates a display clock signal; wherein: the scanning starting signal includes a first pulse and a second pulse which respectively correspond to the first and second pixel row selection steps for every frame period, an interval between the first pulse and the second pulse of the scanning starting signal which is generated in a certain frame period differs from the interval between the second pulse and a first pulse of the scanning starting signal which is generated in a frame period next to the certain frame period, the display control circuit makes the first driving circuit perform, in response to the scanning starting signal, at least twice, the steps for selecting the pixel rows over the pixel array for every frame period of the inputted video data, and transfers, in the first pixel row selection step, display data formed based on the video data to the second driving circuit in response to the display clock signal, and the second driving circuit supplies the first display signal that is generated based on the display data in the first pixel row selection step to the pixel array in response to the second clock signal, and supplies the second display signal which makes the pixel array darker after supplying of the first display signal to the pixel array in response to the second clock signal in the second pixel row selection step.
