  • what typs of television.............

    our faithfull black and white Cathode Ray tube has finally called time and expired, therefore we are going to update to one of these new fangled slim televisions, probably a 42" or 46" jobbie, however what is best, L.E.D., Plasma, or L.C.D.

    we only watch a few programmes a week, plus the odd Giraffe video and dont have / will not have SKY therefore freeview will be enough in addition to the main channels

    Hi Mate,

    I would think LCD would be the best just for a normal telly. Think most of them now are HD too.

      Plasma TV
      Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel.

      Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images.

      LCD TV
      LCD televisions, on the other hand, use a different technology.
      Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer.
      Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is needed for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself.

      Plasma vs LCD
      The ADVANTAGES of Plasma over LCD are:
      1. Larger screen size availability.
      2. Better contrast ratio and ability to render deeper blacks.
      3. Better color accuracy and saturation.
      4. Better motion tracking.

      The DISADVANTAGES of Plasma vs LCD include:
      1. Plasma TVs are more susceptible to burn-in of static images.
      2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images.
      3. Does not perform as well at higher altitudes.
      4. Potentially shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements.

      LCD television ADVANTAGES over Plasma include:
      1. No burn-in of static images.
      2. Cooler running temperature.
      3. No high altitude use issues.
      4. Increased image brightness over Plasma.
      5. Lighter weight than Plasma counterparts.
      6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans.

      DISADVANTAGES of LCD vs Plasma televisions include:
      1. Lower contrast ratio, not as good rendering deep blacks.
      2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts).
      3. Not as common in large screen sizes above 42-inches as Plasma.
      4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.

      Hope this helps gents did my back ground work before i spent mega money on tvs

          LED is the new tech to have, and will be the way forward, which ever way you go check how black the black is, if you know what I mean

              Sir, get a second hand colour TV (the cathode ray variant) for a fiver and use the money saved on a nice dinner for you and the Mrs, give daughter with the name that sounds like Aragnafobia some extra pocket money and use the rest on new parts for the car

                      Pioneer plasma.

                      I have a 50inch pioneer plasma and it flows much better than my 1080p samsung LCD. The only thing is you can't have say MTV on for extended periods cause the MTV sign in the top left will burn the image into it. So all you corrie fans will be upset. (sad too)

                        Just check the contrast ratio, on a crap LCD 4000:1 is expected but can go beyond 100,000:1 think LED tellys can run into the millions. Your old duffer eyes wouldn't notice the difference but your wallet would

                        I'd forget plasma, old tech now

                          Pioneer plasma.

                          My pioneers contrast ratio is well into the millions. One thing I wouldn't do and that's rush in and buy some new technology that has just come out. For one thing it'll be overpriced. Two there will be something better two months later etc etc. I picked my choice because the pioneer plasma is voted amongst the best flowing all-round picture bar none. It's that kind of reputation that sells things. They are tried and trusted product. Has anyone here got an Led tv? I'm speaking from experience.

                          Anyway that's my two penneth.

                            Just changed my old crt to a Panasonic plasma. Took me a long time to choose as I think only now flat screens are better. So I went for a Panasonic TXP42V20B.
                            Great picture when conected to direct to my sky dish. I also got 5 years warranty and £250 off.
                            Sony and Panasonic seem to be the best panels at the moment, Samsung not far behind.

                              From a completely non technical angle, there is a 46" Samsung LED in the local crack converters and I have to say that the picture is absolutely awesome. Certainly looks among the best pic I've seen on a TV.

                              I'm not sure of the full spec etc. but at £1250 it's not too silly although still not cheap by any means.

                              LED is supposed to be the way to go, but at the moment they're still LCD just with LED backlighting as opposed to flourescent (one of the main reasons they can be so thin).

                              The big breakthrough will be when they can get the OLED screens to a decent size without you needing a bank loan to get one - the 11" ones are currently around £2500
