Abstract
A method driving an LCD assembly, the LCD assembly including a transmission-type LCD including a display area configured of pixels, a planar-light-source device illuminating the display area, and a driving circuit driving the planar-light-source device and LCD; wherein the driving circuit supplies a control signal controlling the optical transmittance of each pixel to each pixel, the method comprising, for each frame with LCD image display, the steps of: controlling the luminance of the planar-light-source device by the driving circuit such that, when assuming that the control signal equivalent to a driving signal having the maximum value of driving signals input to the driving circuit driving all the pixels making up the display area is supplied to a pixel, the luminance of the pixel is obtained; and controlling the luminance of the planar-light-source device by the driving circuit based on the response speed of a liquid-crystal material making up the pixels.
