ABSTRACT:
A driving circuit for use in a display apparatus for transmitting a video signal to data lines includes a plurality of shift registers; a control signal generating circuit for outputting a control signal which is at the ON level during a period shorter than a pulse width of signals outputted by the shift registers; a switching circuit controlled to be ON or OFF based on the control signal; and a sampling capacitor for holding the video signal sampled by the switching circuit. In such a driving circuit, the plurality of shift registers sequentially output signals so that the periods in which the signals are high are partially overlapped sequentially. The control signal generating circuit outputs a control signal which is at the On level during a period shorter than the signals from the shift registers. Since the switching circuit is controlled to be ON or OFF based on the control signal, a period in which the switching circuit is conductive is short. Accordingly, the number of such switching circuits which are simultaneously conductive is small, thereby applying a capacitance of only a small number of capacitors to a video signal line.
