The Television Buying Guide - TV Screen Types

<body> <h1>The Television Buying Guide - TV Screen Types </h1> <h2>The television screen that you finally choose will determine the quality of your viewing experience.</h2> <p>It is therefore important that you familiar yourself with the different picture tubes and flat panels that are available in the market. Summarised below is the latest information regarding the different kinds of picture tubes and flat screen panels that are currently in the marketplace.<BR> <BR> <strong>Flat picture tubes</strong><BR> Today's most modern televisions have flat picture tubes. Picture tubes always used to have a convex shape - curved from the middle out to the edge. With flat picture tubes there is no curvature of the television screen. Flat tubes offer a better picture than convex tubes when viewed from the side and often feature antiglare glass.<BR> <BR> <strong>Plasma Screens</strong><BR> Plasma television screens work very well under most ambient light conditions because the screen pictures are created by thousands of gas cells emitting ultraviolet light. This means that very bright light does not wash out the image on the screen. The beauty of these flat screens is that, unlike front view projection screens, you don't have to turn off the lights to see the image clearly and easily which make them excellent for watching DVD's and high definition television programmes. Another characteristic of a plasma panel is the extreme viewing angles both vertically and horizontally. With 160 degrees viewing angle, people sitting off to the side of the plasma screen will still be able to see the image without losing any of it.<BR> <BR> <strong>LCD screens</strong><BR> Liquid Crystel Display (LCD) television screens are significantly brighter than most traditional picture tube sets and offer higher picture contrast with no picture flicker. This means that LCD TVs perform well under most ambient light conditions as well as viewing in a lit room. High quality LCD screens also allow viewing up to 80 degrees from the centre of the display. The picture quality of a LCD screen is determined by how close the colour and sub-colour pixels are to each other (called dot pitch). When choosing a LCD screen it is important to remember that the higher the dot pitch then the sharper and more realistic the picture will be.<BR> <BR> <strong>Rear Projection Screens<BR> </strong>Rear projection televisions have very large screens, however they are generally lighter and slimmer than traditional Tube TV cathode ray tube (CRT) televisions. They work on the principle of a projector inside the television that transmits the picture by bouncing it off thousands of tiny mirrors. The market is now split between Liquid Crystal Display (LCD), Digital Light Processing (DLP) and Liquid Crystal on Silicon (LCOS) units with specific brands now focusing on individual technologies. These television units can now provide excellent picture quality in both fully lit and darkened room.<BR> <BR> <strong>The picture frequency</strong><BR> Picture frequency (or picture flicker) of 100Hz is a relatively new advance. Ordinary televisions flicker at 50 Hz, which is sufficiently high for most people not to notice. Screen flicker is barely obvious when the TV is viewed from the front, but when viewed at an angle it becomes noticeable. 100 Hz screens eliminate the flicker effect making viewing a more pleasurable experience - but this does come at a higher price.</p> <p>Please note that many manufacturers have have developed their own brand names for specific screen technologies, which is why you may find different names amongst similar television models.</p> <p>Further Useful Information <BR> <BR> <A href="http://www.televisionbuyingguide.co.uk/guides/SizesAndFormats.html"><strong>Screen Sizes and Formats </strong></A><strong><BR> <A href="http://www.televisionbuyingguide.co.uk/guides/Step2.html">Back to Step 2 - TV Screen Guide </A></strong><A href="Step2.html"></A></p> <H4><FONT size=3>To find out more about latest televisions at lowest prices just visit our <A href="http://www.televisionbuyingguide.co.uk/company/Map.html"><B>Site Map</B></A></FONT></H4> <P><B>Useful Televison Buying Guide page links:</B></P> <P><A href="http://www.televisionbuyingguide.co.uk/guides/Step1.html"><B>STEP 1</B></A> - Visit our Television Type Guide<BR><A href="http://www.televisionbuyingguide.co.uk/guides/Step2.html"><B>STEP 2</B></A> - Look at our Television Screen Guide<BR><A href="http://www.televisionbuyingguide.co.uk/guides/Step3.html"><B>STEP 3</B></A> - Search for the Latest TV Models and Prices<BR><A href="http://www.televisionbuyingguide.co.uk/company/Jargon.html">Television Jargon Buster</A><BR><A href="http://www.televisionbuyingguide.co.uk/guides/BrandGuide.html">TV Brands</A><BR><A href="http://www.televisionbuyingguide.co.uk/guides/HiDef.html">High Definition Television</A><BR><A href="http://www.televisionbuyingguide.co.uk/guides/ScreenTypes.html">Types of TV Screen</A></P> <H6><FONT size=2>This Television Buying Guide is designed through consumer research to give you a clearer picture on all your TV purchases </FONT></H6><A href="http://www.televisionbuyingguide.co.uk/index.html"><FONT size=2>Home</FONT></A><FONT size=2> | <A href="http://www.televisionbuyingguide.co.uk/company/Disclaimer.html">Disclaimer</A> | <A href="http://www.televisionbuyingguide.co.uk/company/Contact.html">Contact Us </A>| <A href="http://www.televisionbuyingguide.co.uk/company/Privacy.html">Your Privacy</A> | <A href="http://www.televisionbuyingguide.co.uk/company/Map.html">Site Map</A> | <A href="http://www.televisionbuyingguide.co.uk/company/Status.html">Our Independent Status</A></FONT> <H6>Copyright © Blue Lagoon 2006</H6></body>
