Abstract:
1. A driving method for a liquid crystal display device assembly that includes (A) a transmissive-type liquid crystal display device including a display area having pixels disposed in a two-dimensional matrix and at least one color filter corresponding to each pixel, the liquid crystal display device including a liquid crystal material disposed between a front alignment film and a rear alignment film, the front and rear alignment films disposed between a front polarization film and a rear polarization film, (B) a planar light source device including P×Q planar light source units corresponding to virtual P×Q display area units, taking the display area of the transmissive-type liquid crystal display device to be divided into the virtual P×Q display area units, the planar light source device illuminating the display area units corresponding to the planar light source units from a back surface of the display area units, and (C) a drive circuit that drives the planar light source device and the transmissive-type liquid crystal display device, the drive circuit supplying a control signal to each pixel for controlling the light transmittance of the pixel, the driving method comprising the step of: taking a value of an input signal input into the drive circuit for driving the pixels to be indicated by x, the input signal originating from pixels in each of the display area units, when a value x of the input signal for any of the pixels forming the display area unit is greater than or equal to a predetermined value, the value of the input signal being indicated by x taking values of the input signals input into the drive circuit for driving the red light-emitting sub-pixel, the green light-emitting sub-pixel, and the blue light-emitting sub-pixel to be indicated by x
