Abstract:
1. A display device comprising: a display panel in which a plurality of pixels are arranged; a backlight section including (i) a plurality of light-emitting elements arranged in a matrix manner and (ii) a plurality of photosensors arranged in a matrix manner; a video signal processing section configured to carry out a video signal process with respect to an input video signal supplied to the display device; a light-emitting element control section configured to carry out control in which (i) an output luminance of at least one light-emitting element of the plurality of light-emitting elements whose measured luminance is deviated from a reference luminance or (ii) output luminances of peripheral light-emitting elements which are provided around the at least one light-emitting element are corrected, respectively, by use of control information of the plurality of light-emitting elements, which control information contains (a) information on measured luminances of the plurality of light-emitting elements, the information being obtained by the plurality of photosensors and (b) positional information of the plurality of light-emitting elements, the positional information being obtained by the plurality of photosensors; and a display control section configured to control, on the basis of (i) a plurality of video signals which have been subjected to the video signal process and are supplied from the video signal processing section and (ii) the control information supplied from the light-emitting element control section, (a) levels of video signals to be supplied to pixels corresponding to the at least one light-emitting element, whose output luminance is corrected or (b) levels of video signals to be supplied to pixels corresponding to the peripheral light-emitting elements, whose output luminances are corrected, the reference luminance being a luminance which is associated with an expected output from each of the plurality of light-emitting elements, wherein
