Abstract
When time division gradation display is carried out by setting a display state of an electro-optic element capable of R-gradation display A times in one frame period, the present invention determines the weights of the bit data to be such as 2:2:2:2: . . . , in which a conventional ratio regulation of 2:2:2:2: . . . i.e., 1:2:4:8: . . . is changed by at least one part at or later the third bit so as to satisfy the relation of B<Rwhere B expresses the number of display gradations. With this arrangement, it is possible to realize the time division gradation display with a desirable number of scanning lines and the desirable bit weight ratio, without significantly changing the actually-recognized image. On this account, the range of the electro-optic device, capable of setting each stage of outputs in the frame period to be a desirable value, can be enlarged with respect to a matrix display device using the time division gradation display.
