<P>PROBLEM TO BE SOLVED: To provide a backlight module capable of improving the issue of motion blur while maintaining luminance. <P>SOLUTION: The backlight module 20 includes a fluorescent lamp 32, an LED module 30, a controller 22, a lamp inverter 26, and an LED driver 24. The controller 22 generates a first control signal S_CFL and a second control signal S_LED according to a display signal. The lamp inverter 26 drives the fluorescent lamp 32 according to the first control signal S_CFL. The LED driver 24 drives the LED module 30 according to the second control signal S_LED. The LED module 30 is installed close to the fluorescent lamp 32 for compensating the luminance of the fluorescent lamp 32 when turning on and turning off. <P>COPYRIGHT: (C)2010,JPO&INPIT |
