10/6    Hey motd -- is there a significant difference in quality between LCD
        and plasma tv's?  TIA.
        \_ There are big differences.
           LCDs: Limited to about 30", so-so contrast ratio, limited viewing
                 angle, some motion blur, available in fairly high resolution.
           Plasmas: Good contrast ratio, can be larger, limited resolution for
                 non-TV purposes, can burn in if display is static or there's
                 something liek a stock ticker.
           And of course price differences...
           Honestly, unless I really had $5,000 burnign a hole in my pocket,
           wait for prices to come down and the technology to improve, or just
           buy a high-quality CRT-based TV.
           \_ I am not sure about the contrast ratio and viewing angle.  IIRC,
              LCDs are at least as good as Plasmas in these areas.  It may
              indeed be a good idea to wait.  Seems like many of the makers
              of these big screens have been aggressively expanding
              capacity, and now have too much capacity, possibly leading
              to oversupply and a price war next year, especially if the
              Christmas season turns out to be a dud (been following these
              companies in the stock market).
              \_ Here's a link backing up my contention that LCD has better
                 contrast and viewing angles:

        \_ Plasmas, unlike LCDs, use tons of power.  The biggest ones might have
        a cooling fan.
        a cooling fan.  However, since LCDs are typically smaller I do not know
        if they will consume as much power as a plasma if equal in size.

Comparison Plasma televisions LCD televisions Advantage Screen Size Screen sizes range from 32 inches to 60 inches Sizes range fr om 13 inches to 40 inches, but larger screens are expected soon. Screen Refresh Rates Plasma displays refresh and handle rapid movements i n video about as well as CRT televisions. LCD TVs were originally design ed for data display, and not video. LCD TVs with refresh rates of 16 ms or higher show very little n oticeable artifacts. Burn-in Plasma TVs can suffer from burn in produced by static images. Aft er extended periods, stationary images "burn in" and produce an after-im age ghost which remains permanently on the screen. Newer plasma TVs have addressed burn-in and reduced the issues of older models. LCD TVs Product Life-span Typical plasma TVs have a life span of 20,000 to 30,000 hours, which equates to at least two years, three months of 24/7 usage before the TV fades to half the original brightness. LCD TVs life span i s typically 50,000-60,000 hours, which equates to at least 5 years of 24 /7 use. Weight Plasma displays are fairly heavy, and may need additional supports to be mounted onto a wall. Durability Plasmas are very fragile making them tricky to ship and instal l Unlike the commercials where plasmas are mounted on the ceiling, plas mas are best installed by a professional, and should be installed on a w all that can bear a good deal of weight. End users can easily mount an LCD TV themselves if desired. Shipping Due to their fragile nature, plasma TVs need to be shipped by sp ecialty carriers. Overnight or fast delivery options are not recommended . Special shipping methods and their heavier weight add to higher shippi ng costs. Shipping LCD TVs is not difficult, and is not as expensive as shipping plasma displays. LCD TVs are lighter and far less fragile than plasma displays making shipping easier. Installation Plasmas are heavier, use more power, and run hotter than LCD TVs, and therefore require more planning when mounting them. End users can easily instal l LCD TVs themselves, or can use them just as they use a traditional TV using a stand. Brightness Plasma TVs range from 500-700 cd/m2, but are measured based on a different standard than LCD TVs. When compared under "real world" cir cumstances, plasma TVs brightness is typically closer to 100 cd/m2. Meas ured under the more stringent "real world" standards, LCD TVs average a brightness rating of 450 cd/m2. Performance at High Altitude High altitudes can affect the performance of plasma displays because the gas held inside each pixel is stressed, and has to work harder to perform. Contrast Ratios Current plasmas measure contrast ratios of up to 3000:1. LCD TVs contrast ratios measured in real world situat ions double typical plasma TVs.
