主权项 1. A display device comprising: a display panel including a plurality of display blocks arranged in the form of a matrix; a plurality of lighting blocks configured to emit light toward the display panel, each of the lighting blocks being arranged so as to correspond to at least one row of the matrix and being adjustable; and a signal control unit adapted to receive an image signal, determine display block luminances associated with the display blocks using values related to the image signal, determine light luminances of the lighting blocks using the display block luminances, use the image signal and values that are calculated using both the light luminances and the display block luminances to form a corrected image signal, and provide the corrected image signal to the display panel, wherein the signal control unit is configured to calculate block luminance ratios of the display block luminances to the light luminances and is configured to correct gray levels of the image signal provided to the respective display blocks.
