Since 1800 s was discovered, it has found widespread use, such as infrared mouse, infrared printer, infrared keyboard, and the like. Infrared characteristics: infrared transmission is a point-to-point transmission mode, wireless, too far away, aiming at the direction, no barrier in the middle, namely, no wall penetration, and almost no control on the information transmission progress, IrDA is already a set of standards, and IR receiving/transmitting components are also standardized products. As long as the temperature of all objects in nature is higher than the absolute temperature (-273 ℃), molecules and atoms move randomly, and the surface of each object continuously radiates infrared rays. Infrared is an electromagnetic wave having a wavelength in the range of 760nm to 1mm, and is not visible to the human eye. An infrared imaging device is a device that detects infrared rays radiated from the surface of such an object that are not visible to the human eye.

Although the above method can realize the control of the liquid crystal television, there are still defects, firstly, the above method can not control the liquid crystal television without leaving the remote controller every time, and if the remote controller is damaged, the user can not control the liquid crystal television; secondly, if the distance between the remote controller and the user is long and the user is inconvenient to move, the remote controller is difficult to take, i.e. the remote controller is not friendly to the user with inconvenient movement and is not humanized. The problems make the household appliance electronic product adopting the infrared control technology have larger defects, the applicable scene is limited, and the experience of the user is greatly reduced.
