ABSTRACT:
Aspects of the invention can provide a display device capable of providing stable light control with simplified control and structure. A display device can include light sources in which light control can be performed by controlling the operating conditions. The light sources can include a plurality of lamps having light-emitting diodes (LEDs), respectively. The display device can further include an outside-air temperature sensor that measures the temperature outside the casing in which the plurality of lamps are disposed, and a light-source control unit that controls the operating conditions of the lamps on the basis of the measurement of the outside-air temperature sensor.
