LIQUID CRYSTAL DIMMING DEVICE AND LIQUID CRYSTAL DIMMING METHOD
FIG3 is a diagram illustrating how flicker is seen when the liquid crystal panel according to the embodiment is sequentially driven with respective voltage values while changing the frequency of a rectangular wave
FIG3 illustrates how flicker appears when the above-mentioned liquid crystal panel is sequentially driven at each voltage value while changing the frequency of the rectangular wave. In the same figure, the case where no flicker has been seen is indicated by "A", and the case where flicker has been seen is indicated by "B".
