The invention relates to the technical field of touch / remote control, in particular to a method, device and system for terminal equipment to resist infrared signal interference and the terminal equipment. The method includes the steps that a control part controls an infrared touch transmitting circuit in an infrared touch system to transmit infrared rays; the control part determines whether the terminal equipment receives a first remote control signal or not; when the control part confirms that the terminal equipment receives the first remote control signal, the control part sends a first control command or a second control command to the infrared touch transmitting circuit, wherein the first control command is used for controlling the infrared touch transmitting circuit to stop transmitting the infrared rays, and the second control command is used for controlling the infrared transmitting circuit to reduce the number of infrared transmitting tubes for transmitting the infrared rays. According to the method, device and system for the terminal equipment to resist the infrared signals and the terminal equipment, the problem that infrared touch signals can interfere in remote control signals in the prior art can be solved.
Description
technical field [0001] The present disclosure relates to the field of touch / remote control technology, and in particular to a method, device, system and terminal equipment for anti-infrared signal interference of terminal equipment. Background technique [0002] Some terminal devices (such as computers, TVs, mobile phones and cash machines, etc.) will be equipped with multiple sets of control systems, such as infrared touch control systems and remote control systems in TVs that use infrared touch technology. The system includes an infrared touch transmitting circuit, an infrared touch receiving circuit and a micro control unit (English: Microcontroller Unit, MCU for short). Further, the infrared touch transmitting circuit includes an infrared emitting tube matrix, and the infrared touch receiving circuit includes an infrared receiving tube Matrix, in practical applications, the matrix of infrared emitting tubes and the matrix of infrared receiving tubes are usually made into...
