Patent number: 7227315Abstract: A discharge lamp drive apparatus includes: an inverter circuit; a transformer; a plurality of discharge lamp connection terminals; a plurality of ballast capacitors; a plurality of voltage detection circuits; and a signal processor. Each voltage detection circuit has first and second voltage detection elements constituting a series circuit. Each series circuit has a first end connected with a corresponding one of the discharge lamp connection terminals and a second end connected with a grounding terminal. The signal processor generates a signal indicating an open state of a discharge lamp by using an average value and a peak value of voltages appearing between connection points of the first and second voltage detection elements and the grounding terminals.Type: GrantFiled: February 2, 2006Date of Patent: June 5, 2007Assignee: TDK CorporationInventors: Satoshi Shinbo, Hiroshi Maeda

Patent number: 7205726Abstract: 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.Type: GrantFiled: October 27, 2005Date of Patent: April 17, 2007Assignee: TDK CorporationInventors: Hiroshi Maeda, Satoshi Shinbo, Masahiro Gamou, Satoshi Sugimoto, Nobuo Kitajima, Terumasa Toyoda
