Abstract
A method for controlling an electro-optic device includes a third, a fourth, a first, and a second control steps of supplying a third, a fourth, a first, and a second voltage pulse, in this order. In the first control step, a first limit optical state is reached. In the second control step, a first intermediate optical state is reached. The period of each of the third control step and the fourth control step is set to satisfy a relation W (A→B)=−W (B→A), where W (A→B) is an integrated value of drive voltage and drive time when changing the pixel from an optical state A to an optical state B, and W (B→A) is an integrated value of drive voltage and drive time when changing the pixel from the optical state B to the optical state A.
