摘要 |
PROBLEM TO BE SOLVED: To provide a driving method etc. of an electro optical device which improves flexibility of halftone density setting, when performing gradation display of a pulse width modulation (PWM) system or a frame rate control (FRC) system. SOLUTION: The driving method of the electro optical device for driving with a Multi Line Selection (MLS) driving method includes: a gradation parameter assigning step of assigning display data of N bits (N is an integer equal to or larger than two) corresponding to each dot provided in intersection area of respective common electrodes and respective segment electrodes to a gradation parameter of M bits (N<M, M is an integer equal to or larger than three); and a driving step of applying a driving voltage corresponding to the result of MLS calculation in accordance with an FRC pattern selected on the basis of a part of the gradation parameter to a plurality of segment electrodes in a divided period in association with at least a part of the gradation parameter assigned at the gradation parameter assigning step out of periods provided by dividing a selection period of common electrodes simultaneously selected.
