Abstract:
The present invention extends the battery life of a display device in which local dimming driving is possible more effectively than the prior art. A display device (1) according to the present invention comprises a BL (82), battery (60), control device (10), and display panel (81). The display device (1) can be made to operate in (i) a first local dimming mode or (ii) a second local dimming mode in which the power consumption is different than in the first local dimming mode. An information acquisition unit (110) of the control device (10) acquires first information that is at least one from among (i) information about the battery (60) and (ii) information about the power consumption of the display device (1). A mode selection unit (120) of the control device (10) selects the first local dimming mode or second local dimming mode on the basis of the first information.
