  • Small room, small couch, mother-in-law Barcalounger off to the side? Don't worry about it. Somewhere in the middle are In-Plane Switching (IPS) LCD panels, which offer a better viewing angle at the expense of overall contrast ratio and black level. Energy consumption Loser: Plasma TVs Runner-up: LCD TVs No question, LED TVs have the lowest energy consumption, especially when you turn down the backlight. Toyota Prius drivers, this is the TV for you. LCD TVs are a close second, with the same addendum. Plasmas, especially when you turn up the contrast control (which you need to for them to look their best), just aren't as energy efficient. They are, however, far better than they were a few years ago. If you want to go green, get an LED TV. That said, it won't save you money. Because LED TVs are more expensive than other panels, it will take you years to make up that difference in energy savings (if ever).

    With your typical edge lit display you have one level for the overall backlight. With Smart Dimming, you can brightly light the part of the screen with teh candle, and then all but turn off the LEDs behind the black areas of the screen. Should you expect to pay more for LED TV? What are the benefits of LED vs. LCD? LED TVs like those form Westinghouse Digital are often edge-lit, which means they are generally more energy efficient, weigh less and cost less than full array LED TVs. Some LED TVs are engineered and produced so efficiently that they may even cost less than conventional CCFL lit LCD TVs.

    Check out What is 600 Hz? (plasma) and What is refresh rate? for more info. Viewing angle Runner-up: OLED TVs Loser: LED TVs Almost all LED TVs look worse if you're not sitting directly in front of them (or if you're below them). They'll lose contrast ratio, and in some cases, the colors will change. This is the nature of the technology. Plasmas don't technically do this, though some models have special coatings that limit extreme "off axis" viewing. If you have a wide viewing area (a big couch, chairs off to the side, etc.), most LED TVs won't give the same experience to people sitting off center. The current generation of OLED TVs are curved. So if you move too far off to the side, you'll get the edge on the close side, and still see the image on the other side. There is some reduction of picture quality off axis with the LG OLED (likely because of the color filters), but this isn't as severe as what can happen with LED TVs.

    LED TV retail sales
    With many of us expecting the digital switchover shortly there is and will continue to be a huge wave of LED TV buying amongst those whose old TV's wont operate on the new format. As well as LED TV's there has been an increase in demand for LCD display units for multimedia display advertising as used a lot in hospitals, doctor's surgeries, post offices etc.


    Samsung LED TV becomes popular
    Steven Senior from Luminati, a specialist display units manufacturer explains "There is definitely a growth in the interest in multimedia advertising incorporating LCD and LED TV technology in particular and more generally an increase in other alternative point of sale display units such as dump bins and brochure holders. Retailers and marketers are seeking increasingly flexible and innovative advertising solutions especially given the tough times most industries are facing."


    Advantages of LED or LCD TV's and display units (to be precise the units displays are in LCD but backlit by LED) include the ability to produce very bright images and deep blacks and they can be exceptionally slim, hence their use as an advertising medium. The Samsung LED TV is much more efficient than normal display units and they can produce a much wide colour gamut.
