BACKLIGHT DEVICE, DISPLAY, AND TELEVISION RECEIVER

摘要

A backlight device (3) provided with six sets of light source units including drive circuits (T) for driving cold cathode tubes (20a-20f), respectively, along the direction intersecting the longitudinal direction of the cold cathode tubes (20a-20f) perpendicularly, wherein an inverter control section (control section) (30) drives lighting of the cold cathode tubes (20a-20f) included in each of two sets of light source unit adjoining in the perpendicularly intersecting direction while shifting the phase of on/off period of PWM light control with respect to the two sets of light source unit.
