FAQs (Frequently Asked Questions)
Q:
Why is there no flicker on an LCD Monitor?
A:
Technically speaking, LCDs do flicker, but the cause of the phenomenon is different from that of
CRT monitor -- and has no impact of ease of viewing. Flickering in a LCD monitor refers to usually
undetectable luminance caused by the difference between positive and negative voltage. On the
other hand, CRT flickering that can irritate the human eye comes when the on/off action of the
florescent object becomes visible. Since the reaction speed of liquid crystal in a LCD panel is much
slower, this troublesome form of flickering is not present in LCD display.
Q:
Why is an LCD monitor virtually free of Electro Magnetic Interference?
A:
Unlike a CRT, an LCD monitor does not have key parts that generate Electro Magnetic
Interference, especially magnetic fields. Also, since LCD display utilizes relatively low power, its
power supply is extremely quiet.
