Method for driving electrophoretic display apparatus, electrophoretic display apparatus, electronic apparatus, and electronic timepiece

摘要

An electrophoretic display apparatus driving method that allows DC balance to be achieved and reduces variations in size and color tone of a displayed image that may occur in a partial-screen drive method and related apparatus are provided. The drive method includes a first image display step (S2) of displaying a first image in a first color on a display section, a first image adjustment step (S3) of displaying a background of the first image in a second color, a first image deletion step (S4) of displaying the background of the first image in the first color, a second image display step (S12) of displaying a background of a second image in the second color, a second image adjustment step (S13) of displaying the second image in the first color, and a second image deletion step (S14) of displaying the second image in the second color.

主权项

1. A method for driving an electrophoretic display apparatus including a display section having the following components: a pair of substrates that sandwich an electrophoretic device containing electrophoretic particles; pixels capable of displaying at least a first color and a second color; a pixel electrode corresponding to each of the pixels and formed between one of the substrates and the electrophoretic device; and a common electrode facing the plurality of pixel electrodes and formed between the other substrate and the electrophoretic device, the method comprising:
a first image display step of displaying a first image in the first color on the display section by using a partial-screen drive method for applying a voltage based on a drive pulse signal that repeats a first potential and a second potential to the common electrode and applying a voltage based on a reversal signal or a normal signal of the drive pulse signal to each of the plurality of pixel electrodes to produce an electric field between the pixel electrode and the common electrode so that the electrophoretic particles are moved to redraw an image displayed on the display section; a first image adjustment step of displaying a background of the first image in the second color on the display section by using the partial-screen drive method after the first image display step; a first image deletion step of displaying the background of the first image in the first color on the display section by using the partial-screen drive method after the first image adjustment step; a second image display step of displaying a background of a second image in the second color on the display section by using the partial-screen drive method after the first image deletion step; and a second image adjustment step of displaying the second image in the first color on the display section by using the partial-screen drive method after the second image display step, wherein the second image adjustment step is followed by a second image deletion step of displaying the second image in the second color on the display section by using the partial-screen drive method, and after the second image deletion step, the following first image display step is executed.
