Abstract
A liquid crystal display apparatus that includes a liquid crystal display panel having a liquid crystal layer held between a pair of substrates, a light source whose brightness is controllable, and a normalization processing circuit that converts an image signal to a normalized signal and to a normalization coefficient. In addition, the display apparatus includes an LCD driving circuit that converts the normalized signal to an LCD driving signal for driving the liquid crystal display panel, and a light source driving circuit that converts the normalization coefficient to a light source driving signal for driving the light source. The normalization coefficient is used to set pixel values in a blanking interval of a display screen, and the normalized signal is used to set pixel values in a display area of the display screen.
