Abstract
A driving power supply and a driving circuit are provided which are suitable for use in a high resolution matrix liquid crystal display. A power source circuit generates two selecting potentials and an intermediate potential between the selecting potentials to be supplied to scanning electrodes through a scanning circuit, two potentials close to the intermediate potential to be supplied to signal electrodes through a signal circuit, and potentials for driving the scanning circuit and the signal circuit. A receiving circuit controls the scanning circuit and the signal circuit based on control signals and an image signal and monitors the potential of the power supplied to the liquid crystal display to start the potential generation by the power source circuit when the potential has sufficiently increased.
