Abstract
An HPD circuit of a display, a working method, an integrated circuit and electronic equipment, related to the field of display interfaces. The HPD circuit of a display includes a main control module configured to receive a first control signal from the display, generate a first detection signal based on the first control signal and output the first detection signal to a display interface; and a delay control module configured to receive a second control signal from the display, generate a second detection signal based on the second control signal, set the second detection signal to a high level, and output the second detection signal to the display interface. According to the embodiments, the software delay of a display can be effectively shortened, and an HPD signal can be set to a high level as soon as possible.
