FAQs (Frequently Asked Questions)
A:
Technically speaking, LCDs do flicker, but the cause of the phenomenon is different from that of
CRT monitor -- and it has no impact of the ease of viewing. Flickering in an LCD monitor relates 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 occurs when the on/off action of the
fluorescent object becomes visible. Since the reaction speed of liquid crystal in an LCD panel is
much slower, this troublesome form of flickering is not present in an 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 an LCD display utilizes relatively low power, its
power supply is extremely quiet.
Ergonomics, Ecology and Safety Standards
Q:
What is the CE mark?
A:
The CE (Conformité Européenne) mark is required to be displayed on all regulated products
offered for sale on the European market. This 'CE' mark means that a product complies with the
relevant European Directive. A European Directive is a European 'Law' that relates to health, safety,
environment and consumer protection, much the same as the U.S. National Electrical Code and UL
Standards.
Q:
Does the LCD monitor conform to general safety standards?
A:
Yes. Philips LCD monitors conform to the guidelines of MPR-II and TCO 03 standards for the
control of radiation, electromagnetic waves, energy reduction, electrical safety in the work
environment and recyclability. The specification page provides detailed data on safety standards.
