ABSTRACT With the kind of household appliances increased and the use of remote controller being more and more universal. Many people start to choose IR (Infra-red) remote-operated controller. But the market of IR (Infrared) learning remote controller is not as well as the technology in our country. In paper a design of IR learning remote-operated controller with touch screen is to be discussed to improve the production of IR learning technology. The traditional method for IR coding is collecting the IR signal through Interrupt mode or Query mode by single-chip puter. In some condition this method needs repeat for many times. In paper, PC (Personal Computer) is used to record the whole wave and optimize the wave through software, which makes it easy to finish the decoding for one time; By experiment, the infrared emission distance is turned to be affected by the duty ratio of carrier wave and the current of IR emitting diode. After debugging, the infrared emission distance is increased to 10 meters. The device is also tested by interfering signal. With the da
