Abstract
An electronic device paired with an infrared remote control, includes a display screen having a display area, at least one infrared emitter, at least one infrared receiver, a prism and a processing unit. A prism is adjacent to the at least one infrared receiver for converging the infrared rays from the at least one infrared emitter and the infrared remote control to the at least one IR receiver. A processing unit is for activating and then deactivating the infrared emitters one after another, identifying operations of a user on the display area by analyzing the interception of the infrared rays emitted from each of the infrared emitters, identifying operations of a user according to the infrared signals from the infrared remote control and executing corresponding functions associated with the operations of the user.
