An apparatus for controlling an electro-optical apparatus having a plurality of pixels having charged particles between a first electrode and a second electrode, each pixel including a pixel circuit, the pixel circuit including a first transistor, a second transistor, a third transistor and a fourth transistor, drains of the first transistor and the second transistor being connected to the first electrode, a gate of the first transistor being connected to a drain of the third transistor, and a gate of the second transistor being connected to a drain of the fourth transistor, a predetermined first voltage being applied to a source of the first transistor, a predetermined second voltage being applied to a source of the second transistor,
- wherein a signal, used to turn on or turn off the third transistor, is supplied to a gate of the third transistor;
- wherein a signal, used to turn on or turn off the corresponding fourth transistor, is supplied to a gate of the fourth transistor;
- and
- wherein an image signal, used to define a pixel display state, is supplied to a source of the third transistor and a source of the fourth transistor.
