Abstract: A display apparatus includes a display panel, a display driving module, a backlight module, and a backlight driving module. The backlight module includes a plurality of illumination units. The backlight driving module includes a driving circuit, a plurality of switch units, and a plurality of detecting units. Each of the switch units connects to exactly one of the illumination units, and each of the detecting units connects to exactly one of the illumination units and two of the illumination units simultaneously. When the illumination unit connected to the switch unit corresponding to the detecting unit is damaged, the detecting unit controls the connected switch unit to be turned off for cutting off an electrical connection between the driving circuit and the illumination unit corresponding to the connected switch unit, and the remaining illumination units continue to emit light.
