Getting a new TV soon? Baffled by the choices, rumours and specifications that surround new technology. Well here at ‘Electrical-Deals Behind The Scenes’ we hear these rumours quite often and feel that it is about time we put some of these rumours to bed. So what we’ve got here today are the top ten most common misconceptions on TV technology. Got further questions? We’d be happy to try to answer so just leave a comment below.
1.) ‘TVs with 1080i produce the same quality picture as those with 1080p’
Not true: only 1080p (‘p’ stands for progressive) produces a true Full HD experience, 1080i (‘i’ stands for interlaced) only produces half the picture at any one time. Some TV’s that are HD Ready or 768p can display 1080i but this resolution is not as good picture quality as a Full HD 1080p picture
2.) OLED TVs are the next generation of ‘LED TVs’
Not true: OLED TVs use a completely different panel; so-called ‘LED TVs’ are varieties of LCD. Due to the emergence of 3D TV’s most production of OLED TV’s have been put on hold. Sony being one of those who have halted production of their OLED technology. LG are still pushing it but it will be between 5-7 years before OLED’s are widely available at a similar cost to current LCD/LED Prices. (LCD and LED TV’s will still be around for a while yet.)
3.) LCD TVs are no good for watching sports and action movies
Not true: There was an element of truth to this when LCD and Plasma technology was new and first released. You would get a better picture quality on sports and action films on Plasma. This has now changed. Better quality LCD TVs have much improved refresh rates, and most manufacturers have their own motion processing technology (e.g. Sony’s Motionflow). Watching movies in cinema mode gives a darker, warmer picture alongside 24p native content. As technology has progressed so has the picture quality and capabilities of LCD TV.
4.) LCD TVs produce inferior pictures to CRT and Plasma
Not true: LCD TVs (especially the latest and most developed models) now have a number of different technologies to produce high quality images. An LCD panel is just one small part of an LCD TV. They now have many types of picture enhancement technologies such as XD Engines and Sub Field Drives in which to enhance picture quality to a higher level.
5.) LCD screens are made with liquid crystals
Not true: There is no actual liquid in a liquid crystal. The term refers to a peculiar quality of a certain type of crystal, not its physical appearance. These are referred to as LC’s and are used in many different type of displays currently and are the most common replacement of the old CRT (Cathode Ray Tube) Technology.
6.) You have to directly face an LCD to watch it properly
Not true: On a good quality LCD TV you should be able to sit about 70° off axis and still see a perfectly displayed image. Recently this has improved even more and most LCD’s have quite a wide viewing angle. (e.g Most Sony LCD TV’s are now viewable from as severe an angle as 170° and still see a good picture)
7.) LCDs suffer from inadequate black levels
Not true: Most better quality LCD TVs have much improved contrast ratios to produce high quality colours, with some having a contrast ratio of 1,000,000:1. All new LCD TVs also have Dynamic Contrast for extra detail and depth. It is fair to state here that in a comparison between the best LCD and the best Plasma, the Plasma will have the superior black level.
8.) Screen burn is a problem for all types of TVs
Not true: Whilst screen burn CAN affect all types of TVs, it is often confused with transient image persistence on LCD and Plasma TVs (it’s most common in Plasma models). Screen burn is more prevalent on monochromatic CRT screens. Screen burn is more common with Plasma TV’s and is near enough unheard of on LCD TV’s.
9.) Plasma TVs have been banned under new EU regulations
Not true: New EU legislation will bring in minimum energy performance standards for TVs, Plasma TVs will simply need to be more energy-efficient to conform. Some LCD TVs already offer massive energy savings: the BRAVIA WE5 uses the newest commercially available LCD backlight technology, HCFL (Hot Cathode Fluorescent Lamp), which provides the quality of a CCFL backlight but uses significantly less electricity. Plasma technology is constantly improving too with some of the best in the industry being Panasonic’s new range of Neo PDP panels which are the most energy-efficient and technologically advanced to date.
10.) Bigger is always better when you’re choosing a new TV
Not true: Consumers should always choose a TV that is the right size for the room it will be used in, otherwise some viewing benefits can be lost. However the realistic quality of BRAVIA Full HD allows you to sit closer to the television. That means it’s possible to size up to a larger screen for a more immersive HD viewing experience. On the same understanding however sitting too close to a TV will means the picture will look pixellated and picture quality will be lost.
LCD and Plasma TV’s have infinitely improved since they were first released, as with any new technology there are flaws (…just ask apple) however over time these are fixed and the quality improves. This is what has happened within the TV industry. If you are unsure whether LCD or Plasma would be better for your needs then drop us a comment below and tell us what you watch on your TV most and we will try to help you. Likewise if you have any questions or comments please feel free to leave them below and we’ll get back to you asap.
