LCD Backlight Driving Signal Generator

摘要

The present invention discloses a backlight driving signal generator used in a liquid crystal display (LCD) controller. The backlight driving signal generator is coupled to a backlight driving circuit of the LCD and capable of issuing a first pulse signal and a second pulse signal to control the backlight driving circuit to function accordingly. In a preferred aspect, the backlight signal generator is capable of being adapted for the backlight driving circuit of cold cathode fluorescent lamps (CCFLs) or that of light emitting diodes (LEDs).
