Patent ID: 8482548

Claim:
An electronic device comprising: an infrared touch panel, comprising: at least one infrared emitter to emit infrared signals; a plurality of infrared receivers to receive infrared signals from the infrared emitters; and a microcontroller connected to the at least one infrared emitter and the infrared receivers, and configured for controlling the at least one infrared emitter to emit the infrared signals to the infrared receivers to form a plurality of infrared lines; a display unit divided to a plurality of display areas, each display area corresponding to a different infrared line; and a processing unit, configured for controlling the display unit to display an visual information and determining at least one of the plurality of display areas displaying at least one touch icon if the visual information comprises one or more icons, determining at least one infrared emitter and at least one infrared receiver corresponding to the at lest one display area, and sending a configuration instruction including the information of the at least one determined infrared emitter and the at least one infrared receiver to the microcontroller, informing the microcontroller to turn on the at least one determined infrared emitter and the at least one determined infrared receiver, and turn off the rest of the at least one infrared emitter and the rest of the plurality of infrared receivers; further configured for determining a display area touched by a user, and determining a touch icon displayed on the display area, and executing the function of the touch icon.
