ABSTRACT:
A controller for controlling at least two power circuits comprises a phase-shift selector for generating a reference signal according to variable input signals, the reference signal is programmed to indicate an amount of phase-delay according to a number of CCFL power circuits connected; and a pulse generator for receiving the reference signal and generating a pulse signal CLK in response to the received reference signal, the pulse signal is coupled to the CCFL power circuits connected for initiating the operation of the CCFL power circuits. The controller is used to control energy supplying to an electrical circuit comprising multiple CCFL power circuits and is more particularly to provide phase delay to the electrical circuit. Usually, the electrical circuit is applied to display devices, such as liquid crystal display monitors, liquid crystal display computers and liquid crystal display televisions.
