Abstract
This application provides a driving signal output circuit, a screen driving circuit, a display screen, and an electronic device. An input end of an N-type output circuit is coupled to a row scan driver. A row address selection signal is inputted to a control end of the N-type output circuit. An output end of the N-type output circuit is coupled to a horizontal scan line. When the row address selection signal is active, the N-type output circuit outputs a row scan signal, to be specific, drives a corresponding pixel row to update corresponding content data. When a row address selection signal outputted by a DDIC is inactive, the N-type output circuit outputs an inactive signal.
