Patent ID: 8860654

Claim:
An electrophoretic display device comprising: an electrophoretic panel which is provided with an electrophoretic element which includes a first electrode, a second electrode which faces the first electrode, particle arranged between the first electrode and the second electrode, and an ion different from the electrophoretic particle arranged between the first electrode and the second electrode, wherein the electrophoretic particle moves at an applied voltage greater than that of the ion; and a control circuit which controls the electrophoretic panel, wherein the control circuit controls a data voltage with a value which corresponds to a specified gradation of the electrophoretic element to be applied between the first electrode and the second electrode in a writing period, the control circuit controls a correction voltage which is the opposite polarity to the data voltage and is less than or equal to a predetermined threshold value to be applied between the first electrode and the second electrode in a correction period which is different from the writing period, and the control circuit controls a first absolute value of a first time integration value of a first electric current, the first electric current flows between the first electrode and the second electrode due to movement of the ion during the writing period, a second absolute value of a second time integration value of a second electric current, the second electric current flows between the first electrode and the second electrode due to movement of the ion during the correction period, and the first absolute value of the first time integration value of the first electric current is equal to the second absolute value of the second time integration value of the second electric current.
