ABSTRACT:
A driving apparatus for a display panel generates a cell data comprising a bit series per each column electrode of a display panel. The cell data indicates light emitting or non-light emitting in each cell on a column electrode in accordance with a picture signal. The apparatus generates a resonating amplitude signal having a specified minimum power source voltage by a function of resonance. The apparatus generates power pulses in sequence having a period corresponding to one bit of the cell data by giving a specified maximum electrical potential during a rising period and a falling period of the resonating amplitude signal. The apparatus provided in each column electrode determines a logic level of the bit series of the cell data in order of the bit series, and supplies the power pulse to a corresponding column electrode as a driving pulse when the bit indicates the logic level of light emitting. The apparatus determines a magnitude of power during a writing period of the cell data, and varies the rising period and the falling period of the resonating amplitude signal depending on a result of the determining. The apparatus can save power consumption during a cell data writing step.
