Patent ID: 7663574

Claim:
A display device configured such that one frame forming an image is constituted by a plurality of sub-frames, comprising: a detection section detecting a display ratio of the one frame forming an image; a sustaining pulse control section selecting and outputting one out of 2 or more sorts of sustaining pulses whose peak luminance and light emission efficiency are different for each sub-frame depending on the display ratio, wherein, the sustaining pulse control section outputs a frame having all sub-frames composed of a first sustaining pulse that is able to increase the light emission efficiency in the 2 or more sorts of sustaining pulses upon the display ratio being larger than a first threshold value, the sustaining pulse control section controls to be contained a sub-frame composed of a second sustaining pulse that is able to heighten the peak luminance and a sub-frame composed of the first sustaining pulse in a frame upon the display ratio being smaller than the first threshold value, and the sustaining pulse control section controls a change to select sustaining pulses from the first sustaining pulse to the second sustain pulse to start in order from a sub-frame having a lowest luminance upon the display ratio being changed gradually from larger than the first threshold value to smaller than the first threshold value.
