A recently granted patent (Publication Number: US11909145B2) discloses a detecting circuit for an external display device. The circuit includes a first connector, a display circuit providing a display signal, a switch circuit for power supply, and a control circuit detecting the external display device and controlling the switch circuit. The control circuit turns on the switch circuit upon detecting the external display device and turns it off after a certain duration of non-detection, disconnecting the power supply circuit from the display circuit. The circuit also features a second connector for signal reception, a power switch within the switch circuit, and a detection pin in the first connector for confirming the presence of the external display device.

Moreover, the patent also describes a method for detecting an external display device, involving repeated detection, power supply to the display circuit upon detection, and disconnection of the power supply path after a specified duration of non-detection. The method includes steps for outputting a display signal, converting signal specifications, and utilizing a power switch to control the power supply path. The detection process involves confirming the presence of the external display device by checking for a plug signal in the detection pin of the first connector. This innovative circuit and method aim to efficiently manage power consumption in external display devices by automatically disconnecting power when the device is not in use, enhancing energy efficiency and prolonging the device's lifespan.
