Abstract
An electroluminescent (EL) display apparatus and method are provided. A display screen includes pixels. A pixel circuit of each of pixel includes, in part: a first switch transistor on a path through which current flows from a power line through a driving transistor to an EL device; a second switch transistor to supply an image signal to the driving transistor; and a third switch transistor for initially resetting the pixel circuit before the second switch transistor supplies the image signal. A gate terminal of the first switch transistor is connected to a first gate driver circuit. Gate terminals of the second and third switch transistors are connected to a second gate driver circuit, which includes a second gate signal line connected to both the gate terminal of the second switch transistor of a Nth row and the gate terminal of the third switch transistor of a (N+1)th row.
