Do you need to erase the LCD?
There are two entirely opposite versions of the Internet: "degaussing" and "do not erase"! Personally think that does not require degaussing, reason is: liquid crystal display and CRT display principle are essentially different, will not cause adverse effect of remanence external magnetic field and the metal components of the display on the LCD color and color purity, so the liquid crystal display does not require degaussing circuit or degaussing.
Liquid crystal display and not on the electron emission electron tube to hit the screen light, no firing current, not affected by magnetic fields, not to be demagnetized. But the LCD products have built-in rectifier, a strong magnetic field may have an influence, so that the rectifier output abnormal interference, and display effect.
