  • Display panel drive apparatus for driving a display panel
    Patent number: 7425934
    Abstract: A display-panel-drive apparatus having a drive unit that drives the display panel and a control unit that outputs control signals for controlling said drive unit to said drive unit, the display-panel-drive apparatus is provided with: a drive board of the drive unit; a control board of the control unit; a transmission line that transmits the control signals from the control board to the drive board by way of a removable connector; a detection device that detects when said connector is disconnected; and a control device that controls said drive unit when the detection device detects that the connector is disconnected; and wherein the detection device detects that said connector is disconnected by detecting when the connection terminals of the connector are disconnected.

  • Apparatus and method for driving capacitive load, and processing program embodied in a recording medium for driving capacitive load
    Patent number: 7015649
    Abstract: A capacitive-load drive apparatus is provided with a first oscillation-transition-voltage-generation device which is connected between a first power supply and a capacitive load; a second oscillation-transition-voltage-generation device which is connected between a second power supply and the capacitive load; and a voltage-fluctuation-detection device which outputs a detection signal when the voltage of the first power supply or the second power supply fluctuates outside a specified range; and wherein the first oscillation-transition-voltage-generation device is provided with a first switch device and first inductance and moves the voltage of the capacitive load between a reference voltage and a first voltage by oscillation of the first inductance and the capacitive load; and the second oscillation-transition-voltage-generation device is provided with a second switch device and second inductance and moves the voltage of the capacitive load between the first voltage and a second voltage by oscillation of the s
