There are three major players in the Flat Panel TV market: Plasma, LCD and LED. No single technology should be labeled king. All three technologies have pros and cons and end user preferences should be factored into the decision process. Bottom line, you get the most bang for your buck with a Plasma TV. With that said, we will look at seven categories that will help you understand the debate over Plasma vs. LCD vs. LED.
- Contrast Ratio – Winner Plasma
- Viewing Angle – Winner Plasma
- Color – Tie / slight edge to LED
- Motion – Winner Plasma
- Power consumption — Winner LED
- Glare & Image Burn In — Winner LCD and LED
- Price Point – Winner Plasma
Contrast Ratio: Contrast ratio is a TV’s ability to reproduce dark and light areas on the screen. Most people are looking for a TV that can reproduce multiple shades of black thereby getting around a dark scene where all shades of black blend together. It is a generally accepted fact that plasma TV’s have better contract ratios than LCD or LED TVs. This is because Plasma TVs have individual plasma cells, which automatically turn themselves off on the darker parts of the screen. LCD TVs on the other hand have CCFL back-lighting that can only dim itself. LED TV’s are slightly better than LCD TVs in this category but still don’t compare to Plasma.
Viewing Angle: The primary viewing angle for watching any TV is directly in front of the screen. However, since not all viewers can sit right in front of the screen we need to look at which technology allows us to move left and right of center without sacrificing picture quality. The image of the plasma TV remains almost unaffected for viewers at almost any angle. LED TVs come in second place and LCD coming in last. Although Plasma does provide the best viewing angles in my experience I have not been able to notice a dramatic difference between Plasma, LCD and LED. Therefore don’t get too worried about this category when choosing your next TV.
Color: Plasma, LCD and LED can all produce bright, clear, and true colors. There is no clear winner here as the difference you see on the screen may exist due too different manufactures not because of the specific technology. So you may have to get a visual of the screen in action to notice the differences in models of the same type or two different brands. I give all three a tie or a slight edge to LED in this category. From my experience, the colors on LED TVs are very bright but often create an unrealistic appearance.
Motion: The clear winner in this category is the Plasma. You want each pixel on your TV to refresh at a fast rate or simply put change color as quickly as possible. The faster the refresh rate the less chance the human eye will detect blurring on the screen. TV manufactures measure refresh rate in “hz” count. Plasma TVs come in 600 hz were as LCD and LED TVs only come in 120 or 240 hz. Plasma is a clear winner for people who watch fast moving sports or action movies.
Power consumption: Up to this point it appears that Plasma is the clear choice, until now. LED is the clear winner in this category followed by LCD and then Plasma. LED back lighting is dramatically more efficient than plasma and better than LCD. Plasma TVs consume a lot of power because every sub-pixel on the screen needs to be lit.
Glare and Image Burn In: The first misconception that I must get out of the way concerns lifespan. Plasma, LCD and LED TV’s are in all likelihood going to be working about as well on the day of purchase as on the day you are replacing it with some technology that doesn’t even exist today. With that said, there is still consumer fear over image burn-in on plasma TVs. I believe this fear is over analyzed in the purchasing decision. I still have never seen a plasma TV that has been destroyed by burn-in. However, if you plan on using your TV as a computer monitor or in any application were still or stagnant images will appear on the screen for extended periods of time you should choose an LCD or LED TV. Finally, LCD and LED technology tends to put of less glare from natural lighting. Again, don’t overanalyze this factor; the glass fronts on all TV’s produce some glare. I personally do not see that much of a glare difference between plasma, LCD, and LED TV’s.
Price Point: Plasma TVs are typically lower in price to LCD TVs and significantly lower in price to LED TVs. The price on a large flat panel TV 50-60” is going to be roughly 35% to 50% lower on a Plasma in comparison to a similarly sized LCD or LED TV.
