Abstract:
A matrix display apparatus includes a plurality of current-driven display devices arranged along row and column directions, a first circuit provided for each of the display devices, a plurality of data lines arranged for each column, with the data lines supplying an image data signal to a plurality of pixel circuits included in each one of the columns, and a plurality of row scanning lines for transmitting a scanning signal for selecting row by row the plurality of pixel circuits. The first circuit includes a field effect transistor for supplying one of the display devices with a current, which has a control electrode and two principal electrodes, a first switch connecting the control electrode and one of the principal electrodes of the field effect transistor, and a second switch having one terminal connected to the one of the principal electrodes of the field effect transistor and having another terminal connected to one of the data lines along the column of the first circuit. The first circuits in the column are connected in successively divided manner to the plurality of the data lines through the second switch.
