Abstract
In the liquid crystal display device having a back-light source for illumination, image data is provided to the panel in successive frames such that the optical response of the liquid crystal in each pixel within a frame period has an impulse-like shape. The back-light source is controlled to illuminate the liquid crystal display panel such that the illumination is provided to the pixels for only part of the frame period. The optical response curve has a rising portion followed by a falling portion, and the back-light source is controlled by a timing control module such that the back-light is turned off at least when the optical response curve is in the falling portion. It is also possible to remove the image data from the pixels, or to control the charging and discharging of the electrodes to produce the impulse-like shape.
