Patent ID: 6987510

Claim:
A display panel driver for driving a display panel in which capacitive light emitting cells serving as pixels are formed at intersections between a plurality of row electrodes serving as display lines and a plurality of column electrodes intersecting with said row electrodes in accordance with pixel data for the pixels based on an input video signal, the display panel driver comprising: a pixel data pulse generation circuit which generates pixel data pulses by connecting said column electrodes and a power source line in accordance with said pixel data to apply said pixel data pulses to said column electrodes; a resonance pulse power circuit which generates a resonance pulse power source voltage to apply said resonance pulse power source voltage to said power source line, said resonance pulse power circuit changing the resonance amplitude of said resonance pulse power source voltage while keeping a maximum voltage of said resonance pulse power source voltage in accordance with a pattern of a pulse sequence of said pixel data pulses; a power prediction circuit which determines a predicted power consumption of said resonance pulse power circuit based on said pixel data for one field; and a power consumption control circuit which controls said pixel data pulse generation circuit so as to adjust the power consumption of said resonance pulse power circuit in accordance with said predicted power consumption.
