Method for driving display device

摘要

Objects are to provide a display device in which images with higher quality are displayed by a reduction in afterimages of a previously displayed image, and to reduce power consumption of the display device. A pixel in the display device is initialized to suppress an afterimage due to the previous gray level of a display element. Specifically, a voltage applied to the display element for initialization and the time for applying the voltage are changed in accordance with the previous gray level of the display element. Initialization of the display element can prevent an afterimage of a previously displayed image.

1. A method for driving a display device including an electrode, a counter electrode, and a display element placed between the electrode and the second counter electrode, the method comprising the steps of: in a first period, initializing or setting the display element to a first desired gray level while a first potential is applied to the counter electrode; in a second period following the first period, maintaining application of the first potential to the counter electrode, applying the first potential to the electrode, and switching a potential of the electrode and a potential of the counter electrode from the first potential to a second potential while maintaining application of a substantially zero voltage to the display element during the second period, independently of data to be displayed by the display element; and in a third period following the second period, initializing or setting the display element to a second desired gray level while the second potential is applied to the counter electrode, wherein a timing of switching the potential of the electrode is substantially the same as a timing of switching the potential of the counter electrode, and wherein the first potential and the second potential each have a value equal to or greater than a ground potential.
