The present invention provides a method for modulating backlight sources for flat panel displays (FPD), which comprises: lowing steps: step 31 : turning on a display screen; step 32 : identifying whether the total number of the BLL groups provided on the backlight module is an odd number or an even number; step 33 : turning on the one BLL group located at the center-most region of the backlight module while the total number of the BLL groups is an odd number; step 34 : turning on the two BLL groups located at the center-most region of the screen while the total number of the BLL groups is an even number; step 35 : turning on the two backlight groups located at the two outer side of the center turned-on backlight groups while turning off the center turned-on backlight groups, and similarly, progressing the turning-on and the turning-off from the center region to the two outer edge of the backlight module and then reverse-progressing respectively from the two edges to the center region, so as to complete a full cycle; step 36 : determining whether the display screen is off; if so, the process proceeds to step ( 37 ); otherwise, the process goes to step ( 31 ); and step 37 : ending the process.
