<p><P>PROBLEM TO BE SOLVED: To provide a method and a device of controlling light emission flicker of a cold cathode by a digital sound source of a mother board capable of forming a beautiful formation by the light emission flicker on a housing or peripheral part of a computer. <P>SOLUTION: The entitled device has at least one cold cathode fluorescent lamp (CCFL), a mother board, and a control circuit. A high-voltage wire is connected to the cold cathode (CCFL), and at least a monochromatic light is emitted by the discharge of the high-voltage power source. A sound effect software is arranged on the mother board, and a light emission pulse signal is outputted to the control circuit. The control circuit is electrically connected to the high-voltage wire of the cold cathode (CCFL), receives the light emission pulse signal, converts it into the high-voltage power source, and makes the cold cathode (CCFL) emit light and flicker. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
