Patent ID: 7916115

Claim:
A liquid crystal display comprising: a light source made of a plurality of light emitting tubes, at least one of said plurality of light emitting tubes having plural kinds of phosphors in which each of the plural kinds of phosphors of said at least one of said plurality of light emitting tubes has a different luminance response with respect to a luminance response of another of the plural kinds of phosphors of said at least one of said plurality of light emitting tubes, and said at least one of said light emitting tubes having a turned-on state and a turned-off state within one frame; a liquid crystal panel for adjusting the amount of light transmitted from said light source; and a light source drive circuit controlling said light source; wherein said light source drive circuit controls a luminance factor area of light from one phosphor of said plural kinds of phosphors of said at least one of said plurality of light emitting tubes or a change in luminance factor per time of said light of said one phosphor of said plural kinds of phosphors of said at least one of said plurality of light emitting tubes so as to be substantially equal to that of light from any other phosphor of said plural kinds of phosphors of said at least one of said plurality of light emitting tubes in at least one of a luminance rise time when said light source changes from said turned-off state to said turned-on state and a luminance fall time when said light source changes from said turned-on state to said turned-off state.
