For a target pixel to be processed among plural pixels, when a comparison result between the gray level value stored in the first memory and the gray level value stored in the second memory, and the remainder frequency stored in the third memory meet a predetermined condition, the control device rewrites the remainder frequency to a set value decided according to the gray level value stored in the second memory, and the control device performs a cleanup processing to display a predetermined image at the plural pixels with a predetermined timing.

主权项

1. A control device comprising:
a memory control device that controls access, for each of plural pixels whose gray level changes from a first gray level to a second gray level by voltage application multiple times in a predetermined period as the unit, to a first memory that stores a present gray level value, a second memory that stores a gray level value to be displayed next, a third memory that stores a remainder frequency of voltage applications, and a fourth memory that stores a difference between the frequency of applications of a first voltage by which the pixel is changed to the first gray level and the frequency of applications of a second voltage by which the pixel is changed to the second gray level; and a drive control device that controls, for a target pixel to be processed among the plural pixels, to apply a voltage to the target pixel, when the gray level value stored in the first memory and the gray level value stored in the second memory are mutually different, and the remainder frequency stored in the third memory is not zero, the drive control device rewriting, for the target pixel, the remainder frequency to a set value decided according to the gray level value stored in the second memory, when a comparison result between the gray level value stored in the first memory and the gray level value stored in the second memory and the remainder frequency stored in the third memory meet a predetermined condition, the drive control device performing a cleanup processing that includes displaying a predetermined image at the plural pixels with a predetermined timing, wherein the cleanup processing includes an adjustment processing of writing an adjustment image to the multiple pixels by voltage application thereto until the difference meets a predetermined end condition.
