摘要:
The present invention is directed to a discharge lamp drive device and a liquid crystal display device, capable of keeping a tube current balance among discharge lamps to thereby prolong life durations of the discharge lamps. A drive circuit 311 outputs an AC voltage. Ballast circuits 312, 322 include “n” pieces of ballast capacitors C11 through C1n and C21 through C2n, respectively. The ballast capacitors C11 through C1n and C21 through C2n have one ends commonly connected to one another and directed to drive circuits 311 respectively, and other ends individually connected to discharge lamp connection terminals, respectively. Connected in parallel to at least two of ballast capacitors C11, C21, and C1n, C2n, are tube current compensation capacitors Cb3 and Cb1 thereby increasing capacitances of the ballast capacitors, respectively.

There are provided a discharge lamp drive apparatus which can detect that both ends of at least one of a plurality of discharge lamps is in an open state in a differential drive scheme, and a liquid crystal display apparatus. A first current detection circuit 31 detects a current flowing through a first discharge lamp connection terminal group P1 or a current flowing through a second discharge lamp connection terminal group P3, and generates a first current detection signal S1. A second current detection circuit 32 detects a current flowing through the second discharge lamp connection terminal group P2 or a current flowing through a fourth discharge lamp connection terminal group P4, and generates a second current detection signal S2. A signal processor 30 receives the first current detection signal S1 and the second current detection signal S2, and generates a signal S01 which is used to detect an open state of a discharge lamp based on intensities of both the current detection signals S1 and S2.
