Abstract:
A backlight module includes fluorescent lamps, an inverter for supplying power for the lamps, dimming circuits each connecting the lamp in series, a signal processor for converting a video signal into a dimming signal, and a control unit. The lamps are disposed as an array having more than two columns and two rows on a substrate. The control unit electrically connects the signal processor and the dimming circuit and changes the luminance of the lamps by adjusting the dimming circuit according to the dimming signal.
