Display Device And Display Control Method

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 for carrying out a video signal process with respect to an input video signal supplied to the display device;
• and
• an area driving section for supplying to the plurality of light-emitting elements, as light-emitting element data, output luminances modulated in accordance with levels of video signals to be supplied to pixels in one of a plurality of small regions into which a display region, which is constituted by the entire plurality of pixels, is divided,
• the area driving section including a light-emitting element correcting section and a luminance data creating section,
• the light-emitting element correcting section creating a light-emitting element correction signal obtained by correcting (i) an output luminance of a specific light-emitting element whose measured luminance is deviated from a reference luminance or (ii) output luminances of peripheral light-emitting elements which are provided around the specific light-emitting element by use of (a) the light-emitting element data supplied from the area driving section, (b) the information on the measured luminances of the plurality of light-emitting elements, the information being obtained by the plurality of photosensors, and (c) the positional information of the plurality of light-emitting elements, the positional information being obtained by the plurality of photosensors,
• the luminance data creating section controlling levels of video signals, to be supplied to (a) pixels corresponding to the specific light-emitting element whose output luminance is corrected or (b) pixels corresponding to the peripheral light-emitting elements whose output luminances are corrected, so that pixels, located around a pixel corresponding to a center of the specific light-emitting element, have transmittance distributions which exhibit respective changes reverse to those of a luminance distribution of the specific light-emitting element and the peripheral light-emitting elements.

A display control method for use in a display device which displays a video on a display panel by modulating, on the basis of a video signal, transmittances of a plurality of pixels which transmittances are shown when light emitted from a plurality of light-emitting elements, which are arranged in a matrix manner with respect to the display panel including the plurality of pixels, transmits through the plurality of pixels,

• said display control method comprising the steps of:
• correcting luminances of peripheral light-emitting elements, which are provided around a specific light-emitting element, so as to compensate a luminance deviation of the specific light-emitting element from a reference luminance;
• and
• correcting transmittances of peripheral pixels, located around a pixel corresponding to a center of the specific light-emitting element so that the peripheral pixels have transmittance distributions which exhibit respective changes reverse to those of a luminance distribution of the specific light-emitting element and the peripheral light-emitting elements.
