Abstract
A method for controlling an electro-optic device switches between a first driving scheme for changing an optical state between a-number of optical states and a second driving scheme for changing an optical state between b-number of optical states (b>a). In the first driving scheme, an integrated value W (A→B) of drive voltage and drive time when changing an optical state A to an optical state B, and an integrated value W (B→A) of drive voltage and drive time when changing the pixel from the optical state B to the optical state A satisfy a relation of W (A→B)=−W (B→A), and the integrated value W (A→B) and W (B→A) for the optical state A and B in the second driving scheme are equal to the integrated value W (A→B) and W (B→A) in the first driving scheme, respectively.
