Abstract:
1. A display device, comprising: a display panel on which pixels corresponding to respective intersections of row lines and column lines are provided in a matrix manner; a row drive circuit which receives a row drive timing signal for driving the row lines of the display panel, and sequentially supplies row drive signals for driving the row lines to the respective row lines connected to the pixels, in accordance with the row drive timing signal; a column drive circuit which receives display data and a column drive timing signal for driving the column lines of the display panel, and supplies column drive signals corresponding to the display data to the respective column lines connected to the pixels, in accordance with the column drive timing signal; and a control device which receives the display data, a data enable signal, and a clock signal, generates the row drive timing signal from the data enable signal and the clock signal and outputs the row drive timing signal to the row drive circuit, and generates the column drive timing signal from the data enable signal and the clock signal and supplies the column drive timing signal to the column drive circuit, along with the display data, wherein: the control device generates the row drive timing signal with reference to a timing of inputting the data enable signal and supplies the row drive timing signal, which has been generated, to the row drive circuit, so that one of the row drive signals is supplied to a first output terminal of the row drive circuit during a period from the timing of inputting the data enable signal to a start of the column drive circuit outputting the column drive signals of a first horizontal period of one vertical period, and the row drive timing signal includes: a pulse shifted start pulse signal for determining timings to serially output the row drive signals to respective row lines; and a shift clock signal for determining a timing to shift the start pulse signal.
