Driving method for electro-optical apparatus, driving circuit therefor, electro-optical apparatus, and electronic equipment
First Claim
1. A method of driving an electro-optical apparatus, which includes a set of sub-pixels that adjoin one another and that are disposed correspondingly to intersections between scanning lines, which are formed in a direction of a row, and paired data lines, which include first and second data lines formed in a direction of a column, as one pixel, comprising the steps of:
- turning each of said sub-pixels of said one pixel on or off in a first predetermined mode according to corresponding bits of gradation data, which designate a gradation level of said pixel and are supplied through a corresponding first data line;
supplying a voltage signal, which corresponds to the gradation level of said pixel, through a corresponding second data line; and
applying the voltage signal in a second predetermined mode in common to said sub-pixels of said one pixel.

Abstract
The invention obtains high-quality display by suppressing display unevenness. Sub-pixels are disposed correspondingly to each set of the intersections between 3m pairs of paired scanning lines, which are formed in such a manner as to extend in the X-direction, and n pairs of paired data lines, which are a digital data line and an analog data line and extend in the Y-direction. Further, a set of sub-pixels consecutively arranged in the Y-direction is driven as one pixel. In this case, in a first mode, each of the sub-pixels of one pixel turns on or off according to gradation data representing the gradation level of this pixel. Further, in a second mode, a voltage signal representing the gradation level of this pixel is applied to the sub-pixels of one pixel. Furthermore, in a first case of the second mode, the voltage signals are supplied by the first data line driving circuit in line sequence. Moreover, in a second case of the second mode, voltage signals are supplied by a second data line driving circuit in point sequence.
