INFRARED REMOTELY CONTROLLED CIRCUIT

摘要

An infrared remotely controlled circuit employed in an electronic device which includes a display panel and a host machine. The infrared remotely controlled circuitry includes a first remotely controlled circuit, a second remotely controlled circuit, and a microprogrammed control unit (MCU). The first remotely controlled circuit includes a first infrared receiver for mounting in the display panel and a first diode with the cathode connected to a first port of the first infrared receiver. The second remotely controlled circuit includes a second infrared receiver for mounting in the host machine and a second diode with the cathode connected to a first port of the second infrared receiver. The MCU is connected to the anode of the first diode to form a first signal input port and the anode of the second diode to form a second signal input port.
