Control device and display device

A display device comprising:

• an image display panel, wherein the image display panel has pixels arranged in a two-dimensional matrix manner in a row direction and a column direction, wherein the pixels display colors in accordance with lighting amounts of self-light-emitting bodies, wherein the image display panel displays an image for each display frame, and
• a controller that calculates output signal values to the respective pixels for each row in the column direction based on pixel signal values for causing the pixels to display certain colors,
• the controller comprising:
• a line integrating unit that calculate a line integrated value by totaling the pixel signal values for the respective pixels within a line pixel group, the line pixel group including a plurality of pixels arranged in a row in the row direction;
• a frame integrating unit that calculates a frame integrated value by totaling the output signal values for the respective pixels of a former arranged pixel group, the former arranged pixel group including a plurality of pixels that are arranged in rows other than the line pixel group and for which the output signal values have already been calculated in the same display frame;
• a power consumption adjustment term determining unit that calculates a power consumption adjustment term common to the respective pixels within the line pixel group based on a frame threshold that is a predetermined threshold for power consumption in the display frame, the line integrated value, and the frame integrated value;
• and
• an output signal generating unit that calculates output signal values for the respective pixels of the line pixel group based on a pixel signal value to its own pixel within the line pixel group and the power consumption adjustment term.
