Abstract
A matrix type display apparatus includes a video signal voltage compensation circuit for suppressing distortion of a video signal produced on a video signal transmission bus mainly by the wiring resistance and a parasitic capacitance. The video signal voltage compensation circuit is connected to the input end of the video signal transmission bus to compensate waveform distortion of a video signal occurring on the video signal transmission bus while it is supplied to sample-hold circuits connected to the bus. The compensation circuit also includes a filter whose correction coefficient is varied in response to elapsed time from reception of a horizontal synchronizing signal.
