FAQs (Frequently Asked Questions)
A:
Technically speaking, LCDs do flicker, but the cause of the phenomenon is
different from that of a 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 low 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 99/03
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.
