Abstract:
1. An electroluminescent (EL) display apparatus comprising: a display screen having: a plurality of pixels, each pixel of the plurality of the pixels including an EL device and corresponding to a plurality of intersections, each of the plurality of the intersections being formed at a plurality of points where each of the plurality of the gate signal lines intersects with each of the plurality of the source signal lines; a driving transistor configured to be provided for each of the plurality of the pixels to supply a driving current to the EL device included in each of the plurality of the pixels; and a gate driver circuit and a source driver circuit configured to control the supply of the driving current from the driving transistor to the EL device, wherein: the gate signal lines are connected to the gate driver circuit, and the source signal lines are connected to the source driver circuit; a control signal level-shifted at the source driver circuit is applied to the gate driver circuit; and the gate driver circuit and the source driver circuit are configured to supply an off signal to the gate signal lines corresponding to predetermined pixel rows and set the predetermined pixel rows in a non-lighting state and to control the supply of the driving current to the EL device so as to move up and down the predetermined pixel rows set in the non-lighting state.
