what is an LED-LCD HDTV?

Q. is it 3-d like with glasses. if it is i want to get one. i just want to make sure that its 3d like in theaters.

A. Not 3D. A conventional LCD set uses a fluorescent lamp for backlighting. An LED set is simply the same LCD TV with LEDs for backlighting. There are several technical advantages of LEDs over fluorescent lamps, but the picture is the same.

Followup per the answer from "Diog." Number one, he didn't seem to understand your question. And number two, his response is not only needlessly insulting to two other responders, but he is also quite wrong. The picture source on an "LED" TV is absolutely NOT solely the LEDs. They absolutely are the backlight for the same type of LCD picture-forming display that has existed for years. If he or anyone doesn't believe that, there are plenty of references. I've cited one below. He can look it up, and then give consideration to being a bit more courteous while providing bad information.


plasma vs lcd vs led lcd hdtvs?
Q. im planning to get an hdtv soon and was wondering what the real difference between plasma, lcd and led lcd screens are in terms of resolution, contrast ratio, refresh rate, or well just overall image quality. and which type would you recommend for gaming. lastly any particular brand you can recommend?

A. The final decision as to what type of flat panel television to purchase (LCD or Plasma) is really up to you here are pros & cons of each for your decision

Pros of Plasma
- Better contrast ratio
- better ability to render deep blacks, more color depth,
- better motion tracking (response time)
- more availability in very large screen sizes.
Cons of Plasma
- more susceptible to burn-in (although this is not as much of a factor now, due to technology improvements in the past few years)
- more heat generation (as well as more power consumption)
- screen glare in brightly lit rooms
- heavier weight, and more delicate to ship.
Good brand that I would recommend for Plasma is Panasonic or Samsung

Pros of LCD
- LCD television advantages include no burn-in susceptibility
- cooler running
- less screen glare, more functional at high altitudes
- longer display life (although improvements are being made in Plasma screen life)
- looks better in brightly lit rooms
- less power consumption than Plasma.
Cons of LCD
- Lower contrast ratio
- not as good rendering deep blacks
- not as good at tracking motion (although this is improving, especially with the implementation of 120Hz refresh rates (and some now offer 240Hz) on higher-end models).
Good brand for LCD that I would recommend is Samsung or Sony
