Abstract: This application discloses a device display control method, an electronic device, and a communication system, and relates to the field of wireless remote control technologies. This can accurately determine a presentation position of a displayed object (for example, a cursor) corresponding to a control device on a display device and provide better device control experience for a user. In this solution, the presentation position of the displayed object is determined based on a position that the control device points to on a display. Therefore, in both a single-display device scenario and a multi-display device scenario, convenient, immersive, and precise device control experience can be brought to the user.

Abstract: A touch detection drive circuit in an electronic device inputs a touch excitation signal to a touch electrode, and receives a detection signal of the touch electrode. An isolation power supply circuit: receives the touch excitation signal and a primary power supply voltage; based on the touch excitation signal in a non-touch detection phase, short-circuits a first reference ground and a second reference ground, stores the primary power supply voltage, and transmits the primary power supply voltage to the touch detection drive circuit; and in a touch detection phase, disconnects the first reference ground from the second reference ground and discharges to the touch detection drive circuit.
