Abstract
The present application belongs to the technical field of touch detection, providing a touch monitoring circuit, touch display apparatus and electronic device. Sound inside the touch screen is detected by an inside-sound pick-up circuit to generate an inside-screen sound pick-up signal. Sound outside the touch screen is detected by an outside-sound pick-up signal to generate an outside-screen sound pick-up signal. The inside-sound pick-up circuit and the outside-sound pick-up circuit are connected to a signal operation circuit, and the signal operation circuit carries out an XNOR operation on the inside-screen sound pick-up signal and the outside-screen sound pick-up signal, thereby reserving a sound signal transmitted on the touch screen, eliminating a interfering signal inside and outside the touch screen to obtain the screen touch detection signal, and implementing a zero-touch-height detection of the touch screen.
