    摘要： A display device includes a lamp unit, a dimming signal controller, and an inverter device. The dimming signal controller receives a lamp brightness signal and an external environment illumination signal, selects the lamp brightness signal or a signal based on the received external environment illumination signal, and outputs the selected signal as a dimming signal. The inverter device may operate to control brightness of the lamp unit based on the dimming signal.
