Abstract
An EL display apparatus is provided. A display screen includes pixels arranged in a matrix, with each pixel including an EL device and a pixel circuit. A source driver circuit is configured to output an analog video signal to each pixel. A gate driver circuit is on at least one side of the display screen, with the gate driver circuit including first and second gate driver circuits. Each pixel includes a driving transistor, a first switch transistor, and a second switch transistor. A gate terminal of the first switch transistor is connected to a first gate signal line of the first gate driver circuit, and a gate terminal of the second switch transistor is connected to a second gate signal line of the second gate driver circuit. The first and second switch transistors are on/off controlled, independently, by the first and second gate driver circuits.
