Abstract:
A display device includes: an LED control section (4) for carrying out control in which (i) an output luminance of an LED (10) whose measured luminance is deviated from a reference luminance or (ii) output luminances of peripheral LEDs (10) which are provided around the LED (10) is or are corrected, respectively, by using control information of the plurality of LEDs, which control information contains (a) information on measured luminances of the plurality of LEDs, the information being obtained by the plurality of photosensors (11) and (b) positional information of the plurality of LEDs, the positional information being obtained by the plurality of photosensors (11), and a liquid crystal display control section (3) for controlling, based on (i) video signals which have been subjected to the video signal process and are supplied from a video signal processing section (2) and (ii) the control information supplied from the LED control section (4), (a) levels of video signals to be supplied to pixels corresponding to the LED (10), whose output luminance is corrected or (b) levels of video signals to be supplied to pixels corresponding to the peripheral LEDs, whose output luminances are corrected, the reference luminance being a luminance which is originally expected to be outputted from each of the plurality of LEDs.
