18. planar display driving method according to claim 17 also comprises:
If described first object gray-scale value and described the second target gray value equal respectively the described first previous target gray value and the described second previous target gray value, then in the first period of sub-frame of described current frame period, drive described the first pixel according to the first gray-scale value, and drive described the second pixel according to the second gray-scale value; And
In the second period of sub-frame of described current frame period, drive described the first pixel according to the 3rd gray-scale value, and drive described the second pixel according to the 4th gray-scale value;
Wherein, the mean value of described the first gray-scale value and described the 3rd gray-scale value equals described first object gray-scale value, and the mean value of described the second gray-scale value and described the 4th gray-scale value equals described the second target gray value;
Wherein, described the first gray-scale value is in fact less than described the 3rd gray-scale value, and described the second gray-scale value is in fact greater than described the 4th gray-scale value.
19. flat-panel screens according to claim 1, wherein the 3rd gray-scale value deducts the value of this first gray scale and the summation of the value that the 4th gray-scale value deducts this second gray scale is 0.
