摘要： A display panel driving method that can reduce power consumption in a sustain step is provided. Output terminals of a column electrode drive circuit connected to column electrodes of a display panel sustain a state of high impedance during the period of the sustain step. An X sustain signal is set as a bipolar pulse signal, in each half-cycle of which the commencement time of the rise of the negative pulse is set longer than the completion time of the rise of the positive pulse, and the commencement time of the fall of the positive pulse is set longer the completion time of fall of the negative pulse. Furthermore, a Y sustain signal is displaced by a half cycle from the phase of the X sustain signal. It should be noted that the polarity of these pulses may be reversed.

摘要： It is an object of the present invention to provide a display panel driver with which power consumption can be reduced. The display panel driver includes a pixel data pulse generation circuit which generates pixel data pulses by connecting the column electrodes and a power source line in accordance with the pixel data to apply the pixel data pulses to the column electrodes, and a resonance pulse power circuit which generates a resonance pulse power source voltage to apply the resonance pulse power source voltage to the power source line, the resonance pulse power circuit changing the resonance amplitude of the resonance pulse power source voltage while keeping a maximum voltage of the resonance pulse power source voltage in accordance with a pattern of a pulse sequence of the pixel data pulses. A predicted power consumption of the resonance pulse power circuit is determined based on the pixel data for one field, and the pixel data pulse generation circuit is controlled so as to adjust the power consumption of the resonance pulse power circuit in accordance with the predicted power consumption.
