What is the big difference between lcd and led tv’s?
I wanted to get a tv that lasted a long time so i have already opt’ed out plasma. I really want the LED but in the stores i could barely tell the difference from the LCD. I figured it saves electricity but didnt know further than that. Thanks!
The “LED” TV’s use leds to backlight the picture,instead of using a regular flourescent bulb to backlight it,so they should be more reliable in that regard (no CCFL to fail). Also,”LED” tv’s are said to have better blacks than their counterparts. But “LED” tv’s are still LCD’s. They don’t use LED technology to produce the picture,in other words,which is almost deceptive advertising they way they sell them.
If you buy a LCD TV with LED backlights because you believe that the TV is going to last longer, well you are in for a harsh surprise.
Ok, right off the bat, since you’ve written plasma off, that clearly shows that you’ve gathered information that isn’t accurate. Why would plasma fail before another kind of TV?
Any TV can fail long before the hours given, like 60,000 hours touted by LCD TVs. That’s because that’s the life of the back light. That’s only one part of a TV. In plasma TVs, it’s given as half life, or hours to half brightness, often 100,000 hours.
But the two most common failures are video boards and power supplies. So the LEDs in a LCD TV might last for decades, but another part could fail in a month, a year or a decade, the truth is nobody knows.
The only advantage of LEDs are a wider color gamut, and deeper, darker blacks ONLY in a local dimming arrangement. If the panel is ‘edge lit’ to get that razor thin TV, that advantage is lost. While it’s true the LEDs consume less power than LCD, I don’t see it as a big selling point.
If a LCD TV uses 4 dollars of electricity a month, and the LED/LCD TV uses 2.50 a month, are you going to notice? Since power usage varies for from month to month for any household, you’ll never even know if your TV is in fact making any big difference.
To me, image quality is king, so plasma is the first choice, and I’d only go with a LCD TV if I knew that I’d be gaming for long periods of time, or if the display was going to be connected to a PC or Mac.
