Abstract:
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 circuit 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 circuit 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, wherein after the second period, the second electric charge is stored in the n-th row of pixel units and the first electric charge is stored in the k rows of pixel units other than the n-th row of pixel units.
