摘要： A transformer includes a bobbin, terminal electrodes, a core, a primary winding, a secondary winding, and an additional winding. The bobbin is made from an electrically insulating material and has a tubular portion defining an internal space. The tubular portion has an outer peripheral surface providing a first through third sections arrayed side by side in an axial direction of the tubular portion. The terminal electrodes are provided at the bobbin for electrical connection to the windings. The core is inserted into the internal space. The primary winding has an insulating layer and is wound over the first section. The secondary winding has an insulating layer and is wound over the third section. The additional winding is wound over the second section and has an insulation layer whose insulating performance is greater than that of the insulation layer of the primary winding and the secondary winding.

摘要： Discharge lamps are respectively aligned and arranged, and a first alternating voltage output from an inverter circuit is supplied to one electrode of each discharge lamp, whilst a second alternating voltage output from the inverter circuit is supplied to the other electrode of the same. A signal processor compares a first voltage signal with a second voltage signal, and generates a current-limit signal when a difference in amplitude between these signals is not smaller than a predetermined value. The current-limit signal is supplied to the inverter circuit to help reduce the chance on an accidental electric shock.

摘要： 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.
