FAQs (Frequently Asked Questions)A: Technically speaking, LCDs do flicker, but the cause of the phenomenon is different fromthat of a CRT monitor -- and it has no impact of the ease of viewing. Flickering in an LCDmonitor relates to usually undetectable luminance caused by the difference betweenpositive and negative voltage. On the other hand, CRT flickering that can irritate the humaneye occurs when the on/off action of the fluorescent object becomes visible. Since thereaction speed of liquid crystal in an LCD panel is much slower, this troublesome form offlickering 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 MagneticInterference, especially magnetic fields. Also, since an LCD display utilizes relatively lowpower, its power supply is extremely quiet.RETURN TO TOP OF THE PAGEErgonomics, Ecology and Safety StandardsQ: What is the CE mark?A: The CE (Conformité Européenne) mark is required to be displayed on all regulatedproducts offered for sale on the European market. This 'CE' mark means that a productcomplies 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 standardsfor the control of radiation, electromagnetic waves, energy reduction, electrical safety in thework environment and recyclability. The specification page provides detailed data on safetystandards.More information is provided in the Regulatory Information section.RETURN TO TOP OF THE PAGEfile:///D|/My%20Documents/dfu/W9/english/190p5/safety/saf_faq.htm (10 of 10)2004-09-21 9:08:31 AM
