Abstract
A liquid crystal display system includes a liquid crystal display having liquid crystal pixel elements arranged in a matrix; data lines for driving pixel columns and scanning signal lines for driving pixel rows. The system has a circuit for supplying video signal to pixels through data lines and a scanning signal line controller for supplying a progressive scanning signal to the scanning signal lines. The data lines are driven by four sample-hold circuits. The first sample-hold circuit samples and holds video signals for pixels corresponding to odd rows on a first side of the screen and supplies them to data lines corresponding to the first side on the screen based on a first output directing signal. A second sample-hold circuit samples and holds video signals for pixels corresponding to even rows on the first side of the screen and supplies them to data lines corresponding to the first side on the screen based on a second output directing signal. A third sample-hold circuit samples and holds video signals for pixels corresponding to odd rows on a second side of the screen and supplies them to data lines corresponding to the second side on the screen based on a third output directing signal. A fourth sample-hold circuit samples and holds video signals for pixels corresponding to even rows on the second side of the screen and supplies them to data lines corresponding to the second side on the screen based on a fourth output directing signal.
