Patent ID: 7924457

Claim:
An electro-optical device comprising: a plurality of driving transistors turned on or turned off in accordance with a plurality of pulse-width modulation signals each having a plurality of sections for which respective logical levels are set; an electro-optical element electrically connected to drains of the plurality of driving transistors and emitting light at a luminance corresponding to a drive current acquired by combining currents supplied from the plurality of driving transistors; a data signal generator generating a data signal in accordance with a plurality of pieces of data such that, at the beginning of each of the plurality of sections of the corresponding pulse-width modulation signals, the logical level of the data signal corresponds to the logical level of the corresponding pulse-width modulation signal for the corresponding section; and a plurality of pulse-width modulation signal generators provided for the respective driving transistors, each of the plurality of pulse-width modulation signal generators generating a corresponding pulse-width modulation signal by latching the data signal at the beginning of a certain section of the pulse-width modulation signal to be supplied to the corresponding driving transistor and by holding the data signal until the beginning of the next section of the pulse-width modulation signal and supplying the generated pulse-width modulation signal to the corresponding driving transistor.
