Patent ID: 7554535

Claim:
A display device, characterized by comprising: a display section including a display panel including a plurality of pixels arranged in a matrix form at intersections at which a plurality of scanning lines and a plurality of signal lines intersect each other, a scanning line driving circuit for conducting sequential driving control for the scanning lines, and a signal line driving circuit for conducting driving control for the signal lines according to an input video signal; and a lighting section disposed on a rear surface side of the display section, the lighting section including a plurality of lighting devices divided into subareas in a direction parallel to the scanning lines sequentially driven in the display section, a light driving section for controlling on and off of the lighting devices in an independent manner, a control signal generating section for sending a control signal to the light driving section according to an input video signal and a control signal, wherein said control signal generating section sets a ratio between an image gradation display period to conduct image display for the display and a black reset period to display black image therefor according to the amount of movement extracted from the input video signal and the video signal in the image memory, and an image memory for storing a video signal, the light driving section generating a control signal to control on and off timing of each of the lighting devices of the lighting section according to the input video signal, a video signal of a frame preceding a current frame and being stored in the image memory, and the control signal and sending the control signal to the light driving section.
