Emission

CRT monitors generate electrical, magnetic and even radioactive radiation due to the use of high-voltage components necessary for the operation of CRT technology. To achieve acceptable values ​​defined by the increasingly strict standards of the Swedish Confederation of Employers (TCO), the CRT monitor must be equipped with special electronics. High voltage is not necessary to operate an LCD monitor, the monitors are essentially free of emission radiation. The smaller size of the LCD also means that it is easier to incorporate a radiation shield into the monitor's own design and lower costs compared to CRT shielding. In addition to lower emissions, the LCD image is also less disturbed by external radiation or, for example, GSM signals than CRT monitors. Magnetic fields generated by, for example, the proximity of a loudspeaker, mobile phone or electric fan cause major problems with the clarity of the CRT image, while LCDs remain unaffected by interference.
