摘要： A display panel drive apparatus which reduces noise to thereby prevent malfunction. A first switch connects based on pixel data between one of column electrodes of a display panel and a power supply line to which a pulsed supply voltage is applied. A second switch connects between the one column electrode and a ground line based on the pixel data. The first and second switches are used to apply pixel data pulses based on the pixel data to the one column electrode. In this scheme, the pixel data having a lower frequency in the vertical direction of the screen allows the second switch to send a smaller current to the ground line when compared with a case of the pixel data having a higher frequency.

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.
