Display device with compensating backlight drive circuit and method for driving same

An active-matrix display device provided with a backlight including a light source, a plurality of pixel forming portions for forming an image to be displayed by transmitting light from the light source, a plurality of video signal lines for transmitting a plurality of video signals representing the image to be displayed to the pixel forming portions, and a plurality of scanning signal lines crossing the video signal lines, the pixel forming portions being arranged in a matrix so as to be associated with the video signal lines and the scanning signal lines, the device comprising:

• a scanning signal line driver circuit for selectively driving the scanning signal lines during a predetermined scanning period and deselecting all of the scanning signal lines during a hold off period starting upon completion of the scanning period, the scanning period and the hold off period constituting a frame period longer than 1/60 of a second;
• a video signal line driver circuit for providing the video signal lines with the video signals to be transmitted, during the scanning period;
• a backlight drive circuit for controlling the light source included in the backlight so as to be turned on/off multiple times during the hold off period;
• and
• a luminance change storage portion having prestored therein predicted values for luminance changes due to current leakage in an image displayed by the pixel forming portions during the hold off period, wherein,
• the backlight drive circuit calculates emission luminance of the light source multiple times during the hold off period on the basis of the predicted values stored in the luminance change storage portion, and controls the light source so as to be turned on with the calculated emission luminance, thereby compensating for the luminance changes.
