1. An HPD circuit of a display, comprising:
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,
wherein the delay control module comprises a first switch submodule and a second switch submodule, and the first switch submodule is electrically connected with the second switch submodule.
