20100033097LAMP ABNORMALITY DETECTING DEVICE AND INVERTER, BACKLIGHT DEVICE, AND DISPLAY DEVICE WHICH ARE EQUIPPED WITH THE SAME - One embodiment of the present invention relates to a lamp abnormality detecting device that detects an abnormality in a lamp. A maximum/minimum extraction circuit outputs, as a maximum current, a current having a maximum current value among currents supplied thereto from lamp drive circuits and outputs, as a minimum current, a current having a minimum current value. A subtraction circuit calculates a difference between the maximum current and the minimum current and outputs an amplified difference as a differential voltage. A comparison circuit compares the differential voltage with a predetermined threshold voltage and outputs a result of the comparison as a control signal. A control circuit stops the operation of the lamp drive circuit when the control signal indicates that the differential voltage is higher than the threshold voltage.02-11-2010

20090103281BACKLIGHT DEVICE AND DISPLAY DEVICE - In a backlight device, lamp units including cold cathode-ray tubes (straight-tube lamp portions) and inverter circuits (driving circuits) for driving to switch on the cold cathode-ray tubes are arranged along a direction that is substantial perpendicular to a longitudinal direction of the cold cathode-ray tubes. Further, the inverter circuits of the lamp units are disposed separately on one end portion side and other end portion side in the longitudinal direction of the cold cathode-ray tubes. Thereby, even when using the longitudinal cold cathode-ray tubes, brightness on a light emitting surface can be made uniform.04-23-2009
20090262279INVERTER FOR LIGHT SOURCE DEVICE, LIGHT SOURCE DEVICE, DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - In a light source inverter rectifier circuits are respectively connected to a CCFL in a substantially U-shaped lamp and a CCFL in a substantially U-shaped lamp, and the outputs from the rectifier circuits are fed to a stabilization circuit. Thus, the stabilization circuit monitors an average of currents flowing through the substantially U-shaped lamps. This makes it possible to make uniform the currents flowing through the substantially U-shaped lamps.10-22-2009
