Abstract:
1. A driving apparatus of a liquid crystal display apparatus including a liquid crystal cell of a vertically aligned mode driven in a normally black mode, said driving apparatus comprising: correction means for correcting a desired target gradation so as to facilitate a gradation transition from a current gradation to the desired target gradation; judgment means for judging whether or not a combination of the current gradation and the desired target gradation corresponds to a predetermined first combination which causes a time required for a gradation in a second area of a pixel to reach a second target gradation to become not less than a predetermined second tolerance, when facilitating the gradation transition to such a degree that a gradation in a first area of the pixel does not exceed a predetermined first tolerance indicative of a first target gradation, and which causes the gradation in the second area of the pixel to exceed the first tolerance, when facilitating the gradation transition to such a degree that a time required for the gradation in the first area of the pixel to reach the first target gradation becomes less than the second tolerance; first calculation means for adding a predetermined first value to the desired target gradation, when the combination of the current gradation and the desired target gradation corresponds to the first combination, and for supplying an added result to said correction means; and second calculation means for subtracting a predetermined second value from the current gradation, when a combination of the current gradation and a previous gradation corresponds to the first combination, and for supplying a subtracted result to said correction means.
