Driving method for electro-optical device, driving circuit therefor, electro-optical device, and electronic apparatus

A driving circuit for an electro-optical device, wherein a pixel is turned on or off by a subfield, the subfield being a unit obtained by dividing one field into subfields, according to a weighting of gray scale data indicating a gray scale level of the pixel, the pixel being positioned at a location corresponding to each intersection between a plurality of scanning lines and a plurality of data lines, and a reference time of weighting for the gray scale data is shifted every scanning line and every subfield, and a plurality of scanning lines being placed into a plurality of blocks, each of the blocks being selected in a predetermined order in each subfield, and the scanning line in which the reference time of weighting has arrived being selected in a predetermined order in a selected block, and selection of one particular scanning line in the subfield and selection of a scanning line adjacent thereto in the next subfield being performed in an identically numbered horizontal scan period, the driving circuit comprising:

• a scanning line driving circuit that selects a scanning line in which a reference time of weighting has arrived in a predetermined order in each subfield;
• and
• a data line driving circuit that supplies data to the pixel that intersects the scanning line selected by the scanning line driving circuit via the corresponding data line, the data indicating that the pixel is turned on or off.

An electro-optical device, wherein a pixel includes a switching element arranged corresponding to each intersection between a plurality of scanning lines and a plurality of data lines, and a pixel electrode connected to the switching element, the pixel being turned on or off by the subfield, the subfield being a unit obtained by dividing one field into subfields, according to weighting of gray scale data indicating a gray scale level of the pixel, and a reference time of weighting for the gray scale data is shifted every scanning line and every subfield, and a plurality of scanning lines being placed into a plurality of blocks, each of blocks being selected in a predetermined order in each subfield, and the scanning line in which the reference time of weighting has arrived being selected in a predetermined order in a selected block, and selection of one particular scanning line in the subfield and selection of a scanning line adjacent thereto in the next subfield being performed in an identically numbered horizontal scan period, the electro-optical device comprising:

• a scanning line driving circuit that selects the scanning line in which a reference time of weighting has arrived in a predetermined order in each subfield;
• and
• a data line driving circuit that supplies data to the pixel that intersects the scanning line selected by the scanning line driving circuit via the corresponding data line, the data indicating that the pixel is turned on or off.
