Abstract
An electroluminescent (EL) display apparatus and corresponding method of control are provided. A display screen includes pixels arranged in a matrix. A pixel circuit of each of the pixels includes, in part: a second switch transistor to supply, to a driving transistor, an image signal; 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 second switch transistor and a gate terminal of the third switch transistor are connected to a second gate driver circuit. The second gate driver circuit includes a first gate driver circuit and a second gate driver circuit. The second gate driver circuit 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.
