Device and method for driving electro-optical panel, electro-optical device, and electronic apparatus
First Claim
1. A device for driving an active matrix electro-optical panel in which a plurality of pixels in an image display region each have an electro-optical element and active element means for actively controlling the electro-optical element to selectively supply electric charge to the electro-optical element through a source line in response to a write selection signal that selects a horizontal scanning period for storing the electric charge in each row of pixel units, the driving device comprising:
- first driving means for, in a first period of the horizontal scanning period for storing the electric charge in an n-th row of pixel units (where, n is a natural number), simultaneously supplying the write selection signal to k rows of pixel units (where, k is a natural number greater than or equal to
2) including the n-th row of pixel units through write scanning lines arranged to correspond to the respective rows of the pixel units, and for supplying the write selection signal to the n-th row of pixel units in a second period of the horizontal scanning period for storing the electric charge; and
second driving means for simultaneously performing first electric charge supply on the k rows of pixel units arranged along any one of the source lines through the one source line in the first period, and for performing second electric charge supply on the n-th row of pixel units through the one source line in the second period.

Abstract
To increase a current value of a source line at the time of current programming. A device for driving an electro-optical panel in which a plurality of pixels each have an electro-optical element and active element means for selectively supplying electric charge to the electro-optical element through a source line in response to a write selection signal. The driving device comprises: first driving means for simultaneously supplying the write selection signal to k rows of pixel units including an n-th row of pixel units through a write scanning line in a first period of a horizontal scanning period for storing the electric charge in the n-th row of pixels, and for supplying the write selection signal to the n-th row of pixel units in a second period of the horizontal scanning period for storing electric charge; and a second driving means for simultaneously performing first electric charge supply on the k rows of pixel units arranged along any one of the source lines through the one source line in the first period, and for performing second electric charge supply on the n-th row of pixel units through the one source line in the second period.
