The source of natural interference mainly comes from the electric noise in the atmosphere and the cosmic noise in the outer space of the earth. They are not only an important part of the earth's electromagnetic environment, but also radio communication and space technology interference sources. Natural noise can interfere with the operation of satellites and spacecraft, as well as the launch of ballistic missile launch vehicles.
Artificial interference sources refer to electromechanical or other artificial devices that produce electromagnetic energy interference, some of which are devices specifically used to emit electromagnetic energy, such as radio, television, communication, radar and navigation radio equipment, known as intentional emission of interference sources.
It is especially necessary to prevent electromagnetic interference when the device works in these environments. WIWOTOUCH can prevent electromagnetic interference of the touch screen, so that the touch screen can operate in a stable environment.
Protection against electromagnetic interference (EMl) refers to the interference caused by magnetic field leakage to normal data transmission. All live wires create a magnetic field around the central axis. If a metal conductor passes through this magnetic field, an electric current will be generated on the conductor. Similarly, if a conductor passes through an electric field, a magnetic field will be generated around the central axis of the conductor.
The effect of these magnetic fields will affect the touch effect of the touch screen. By adding anti-electromagnetic interference properties to the device, the magnetic field around the device can be stabilized, the stability of the device can be increased, and the desired touch effect can be achieved.
