Abstract
A driving method of a display device comprising a display area including a plurality of pixels arranged in a matrix, comprising a first step and a second step. In the first step, a first signal is input to each of the plurality of pixels and a first image is displayed on the display area. In the second step, a second signal is input to each of the plurality of pixels; an afterimage that appears on the display area in the first step is erased; a second image is displayed on the display area. The second step is performed after the first step.
Claims28
A driving method of a display device comprising a display area including a plurality of pixels arranged in a matrix, comprising the step of:
- a first step of inputting a first signal to each of the plurality of pixels and displaying a first image on the display area;
- and
- a second step of inputting a second signal to each of the plurality of pixels, erasing an afterimage that appears on the display area in the first step, and displaying a second image on the display area,
- wherein the second step is performed after the first step.
A driving method of a display device comprising a display area including a plurality of pixels arranged in a matrix, comprising the step of:
- a first step of inputting a first signal to each of the plurality of pixels and displaying a first image on the display area;
- a second step of inputting a second signal to each of the plurality of pixels, erasing an afterimage that appears on the display area in the first step, and displaying a second image on the display area;
- and
- a third step of inputting a third signal to each of the plurality of pixels and retaining the second image,
- wherein the second step is performed after the first step and the third step is performed after the second step.
A driving method of a display device comprising a display area including a plurality of pixels arranged in a matrix, comprising the step of:
- a first step of setting a potential of a first pixel to a first potential, setting a potential of a second pixel to a second potential, setting a potential of a third pixel to a third potential, and displaying a first image on the display area;
- and
- a second step of setting the potential of the first pixel to the first potential, setting the potential of the second pixel to a fourth potential, setting the potential of the third pixel to the first potential, erasing an afterimage that appears on the display area in the first step, and displaying a second image on the display area,
- wherein the first potential is equal to a potential of a common electrode,
- wherein the second potential is lower than the potential of the common electrode,
- wherein the third potential is higher than the potential of the common electrode,
- wherein the fourth potential is lower than the potential of the common electrode, and
- wherein the second step is performed after the first step.
