Abstract
Official abstract text for this publication.
The present invention proposes a liquid crystal display device and a transforming circuit thereof. One terminal of a first coil connects to input voltage. One terminal of a energy-storage unit connects to the other terminal of the first coil. One terminal of a second coil connects to the other terminal of the energy-storage unit, and the other terminal of the second coil connects to the light source. An input terminal of a unidirectional unit connects to the one terminal of the first coil which is connected to the input voltage, and the output terminal connected to the one terminal of the second coil which is connected to the light source. A driving signal is fed into a controlling terminal of a switch unit. A first terminal of the switch unit is grounded, and the second terminal of the switch unit is connected a medial point between the first coil and the energy-storage unit.
