摘要

When changing a pixel to white in the middle of a writing operation for writing the pixel in black, a new writing operation for writing the pixel in white is started. When changing a pixel to black in the middle of a writing operation for writing the pixel in white, a new writing operation for writing the pixel in black is started. In addition, when a difference between the number of times of application of a first voltage applied to change the pixel to white and the number of times of application of a second voltage applied to change the pixel to black is not a predetermined value at a predetermined timing, the first voltage or the second voltage is applied to the pixel until the difference becomes a predetermined value.

主权项

1. A controller of an electro-optical device which includes a display unit with a plurality of pixels and in which a writing operation of changing the pixel from first gray level to second gray level and a writing operation of changing the pixel from the second gray level to the first gray level are performed by an operation of applying a voltage to the pixel multiple times, the controller comprising:
a number-of-times difference calculating section that calculates a difference between the number of times of application of a first voltage, which is applied to change the pixel to the first gray level, and the number of times of application of a second voltage, which is applied to change the pixel to the second gray level; and a voltage control section that applies the first voltage or the second voltage to the pixel until the difference becomes a predetermined value when the difference regarding the pixel is not the predetermined value at a predetermined timing and that, when changing a gray level of the pixel, starts a new operation of applying a voltage to the pixel multiple times even in the middle of the writing operation.
