Patent ID: 8498041

Claim:
A method of controlling an electrophoretic display element, the electrophoretic display element including a cell containing first electrophoretic particles charged with one of positive polarity and negative polarity and second electrophoretic particles charged with another of the positive polarity and the negative polarity, and a first electrode section and a second electrode section disposed opposite to each other across the cell in a viewing direction of the cell, the first electrode section including a first electrode and a second electrode, and the second electrode section including a third electrode and a fourth electrode, the method comprising: individually controlling application voltages applied to the first electrode section and the second electrode section by applying a pattern of voltages to the first electrode, the second electrode, the third electrode and the fourth electrode such that all of the first electrophoretic particles electrophoretically move within the cell in a first path in a direction along the viewing direction, and all of the second electrophoretic particles electrophoretically move within the cell in a second path different from the first path in a direction opposite to the viewing direction.
