DC/AC and DC/DC power supply for LCD displays |
摘要 |
A voltage power supply circuit is provided that uses the voltage output of an oscillator to provide a high voltage DC output to drive a liquid crystal display device. A controller IC opens and closes an FET to allow the EMF of an inductor to generate a DC voltage that exceeds the battery voltage source for the liquid crystal display device. Accordingly, the oscillator circuit that drives a back light display for a liquid crystal device is simultaneously used to generate the high voltage DC source for the liquid crystal display device.
