which one is better.samsung LED TV or sony LCD?




ali Kassa


I want to buy a new tv and want to compare samsung LED VS sony LCD


Answer
LED TV is always better / much better than LCD TV. and LED TV prices is 2 to 3 X higher than LCD TV. cant compare between LED TV and LCD TV.
Samsung LED is GREAT. Samsung leading in LED TV. world No 1 total quantity sold , 92 % LED TV on the market is by Samsung.
if you afford to paid for Samsung LED TV. go for it. is GREAT.
If you Budget is low ! Sony and Samsung LCD TV both equally good quality / reliable.but both make Standard entry lever / mid-end / hi end LCD model. please compare to the same range of model. prices is main issue !

What kind of HDTV is better: Plasma, LCD , LED, etc.?




FSPT_Tech


I want to buy an 40" - 46" HDTV (1080p) for my home to replace my 10 year old 40 " CRT TV. I've seen different types out there: Plasma, LED. LCD. What's the difference and which is considered best (quality-wise). Any references to links that explain the different types of TVs on the market now. I'm just now able to afford getting into 21st century technology and would like some help.


Answer
Confused about what type of TV to buy? LED LCD Plasma.. How to choose?

After all, there are so many acronyms and buzzwords to wrap your head around, such as 1080p, 120/240Hz, 24p, HDMI and LED backlighting. Huh?

Along with deciding how big a screen you want (which is usually tied to the size of your budget and the dimensions of your room), the next choice should be between LCD.LCD (LED Backlit) or Plasma â and all have their merits. Here, we'll describe each of these formats, and also point out their shortcomings.

LCD

What is it?
lcd tv 120mhzSimilar to your laptop computer's monitor, flat-panel LCD televisions use a liquid crystal display to produce a sharp and bright picture; these crystals are sandwiched between two panes of polarized glass, which are stimulated by an electric current and illuminated by fluorescent tubes housed behind the glass. Some newer LCD TVs, however, use LED-backlighting instead. LEDs, or light-emitting diodes, translate to a better-looking picture (see photo).

Pros
There are a number of advantages to buying a LCD televisions. For one, with more than three-quarters of all televisions embracing this technology, there is a lot of choice when it comes to manufacturers, models and sizes (13- to 103-inches, in fact). Competition, of course, breeds more aggressive pricing, too, which is good news for the consumer.

Flat-panel LCD televisions are also very thin, light and energy efficient, and are ideal for rooms with plenty of ambient light, which, for example, comes through large windows as they tend to absorb rather than reflect light (reflected light can obscure your view of the screen).

Cons
Until recently, LCD TVs didn't handle fast motion images as well as plasma TVs, resulting in a somewhat blurred image. Newer LCD TVs, though, have added technologies such as 120Hz frame doubling (or 240Hz frame quadrupling) to smooth out motion. It's still not as good as plasma, but much better than before. Also, LCD TVs used to have problems showing dark blacks (because a light was still on behind the pixel showing black, resulting in a more greyish hue). Many LCD televisions today use local-dimming with LED-backlighting (see next section) for improved contrast ratios (whiter whites and blacker blacks) - but, keep in mind, this is not an issue associated with plasma TVs.

LCD (LED Backlit)

What is it? Not a Different Type of TV

led lcd tv backlighting backlitItâs tempting to think LEDs belong in a completely separate category beside LCD and plasma TVs, but in reality, an LED television is just a type of LCD TV. The proper term would really be "LED-backlit LCD TV," but that always seems to get truncated to "LED TV" in everyday conversation, perpetuating the confusion.

To understand how LEDs function in an LCD TV, think of an actual liquid-crystal panel as the plastic pegs in a Lite Brite. They hold a translucent image, but without a powerful backlight to punch through and light it up like a signboard, youâre not going to see much. On your old Lite Bright, an inefficient incandescent light did the job, but pretty unevenly. On a typical LCD TV, fluorescent lights provide the backlighting through a special plastic sheet called a light guide that distributes light from a fluorescent tube evenly over the surface of the TV. On an LED-backlit TV, fluorescent tubes are replaced with light-emitting diodes â LEDs â the same technology that probably lights up your digital watch, the buttons on your monitor, and the indicators on your stereo. They can be either situated along the edges of the TV like a fluorescent tube, or arranged directly behind the screen in a grid. But what difference does it make, and why would anyone spend so much money on it?

The Benefit of LEDs

The most obvious reason LEDs have fallen into favor in LCD TVs: theyâre simply more efficient. Although fluorescent lights do a decent job converting electricity to light in the big scale of things, LEDs perform even better. Typically, manufacturers claim an efficiency improvement of up to 30 percent over fluorescent-based sets, which can add up significantly over the lifetime of a TV, especially on larger screens that use more juice to begin with.

LEDs are also much smaller than tubes, even after accounting for the number of them needed to light an entire TV. That means LED-backlit televisions can be manufactured significantly thinner than their tube cousins. For instance, most of the ultra-thin televisions that measured under an inch thick at CES used LED backlights, because they add very little depth to the profile. Though commercial variants arenât quite as dramatically thin as these prototypes, theyâre significantly skinnier than their fluorescent-backlit counterparts, making them some of the most chic and living-room-friendly HDTVs out there.

For home theater enthusiasts, LEDs only matter for one reason: image quality. Because fluorescent tubes mu

How does LED TV work ?




Student





Answer
LED-backlit LCD television (called LED TV by Samsung Electronics, Panasonic,Toshiba, Philips, LG Electronics, ProScan and Vizio and not to be confused with true LED displays) is an LCD TV that uses LED backlighting[1] rather than fluorescent lights used in traditional LCD televisions.

The LEDs can come in two forms, Dynamic RGB LEDs which are positioned behind the panel, or white Edge-LEDs positioned around the rim of the screen which use a special diffusion panel to spread the light evenly behind the screen.[2]

LED Backlighting Techniques
[edit] RGB Dynamic LEDs
This method of backlighting allows dimming to occur locally creating specific areas of darkness on the screen. This can show truer blacks, whites and PRs at much higher dynamic contrast ratios, at the cost of less detail in small bright objects on a dark background, such as star fields.[3]

[edit] Edge-LEDs
This method of backlighting allows for LED-backlit TVs to become extremely thin. The light is diffused across the screen by a special panel which produces a uniform color range across the screen.

Sharp also has LED backlighting technology that aligns the LEDs on back of the TV like the RGB Dynamic LED backlight, but it lacks the local dimming of other sets.[4]

[edit] Differences between LED-backlit and CCFL-backlit LCD displays
LED-backlit LCD TVs differ from conventional CCFL-backlit LCD TVs in the following:

They can produce an image with greater dynamic contrast compared with CCFL-backlit LCD TVs.[5]
With Edge-LED lighting they can be extremely slim. Current models on the market can be less than one inch thick.[5]
They can offer a wider color gamut, especially when RGB-LED backlighting is used.[5]
Lesser environmental pollution on disposal.[5]
Higher cost due to current market product placement.[5]
[edit] Technology
TV manufacturers can use an LED backlight instead of the standard Cold Cathode Fluorescent Lamps (LCD-CCFL) used in most LCD televisions. It is important to distinguish this method of simply backlighting a conventional LCD panel, from a hypothetical true LED display, or an OLED display. LCD-based televisions described as 'LED TVs' are vastly different from self-illuminating OLED, OEL or AMOLED display technologies. In terms of the use of the term 'LED TV' in the UK, the ASA (Advertising Standards Authority) has made it clear in prior correspondence that it does not object to the use of the term, but does require it to be clarified in any advertising. There are several methods of backlighting an LCD panel using LEDs including the use of either White or RGB (Red, Green and Blue) LED arrays positioned behind the panel; and Edge-LED lighting, which uses white LEDs arranged around the inside frame of the TV along with a special light diffusion panel designed to spread the light evenly behind the LCD panel.

An LED backlight offers several general benefits over regular CCFL backlight TVs, typically higher brightness. Compared to regular CCFL backlighting, there may also be benefits to color gamut. However advancements in CCFL technology mean wide color gamuts and lower power consumption are also possible. The principal barrier to wide use of LED backlighting on LCD televisions is cost.

The variations of LED backlighting do offer different benefits. The first commercial LED backlit LCD TV was the Sony Qualia 005 (introduced in 2004). This featured RGB LED arrays to offer a color gamut around twice that of a conventional CCFL LCD television (the combined light output from red, green and blue LEDs produces a more pure white light than is possible with a single white light LED). RGB LED technology continues to be used on selected Sony BRAVIA LCD models, with the addition of 'local dimming' which enables excellent on-screen contrast through selectively turning off the LEDs behind dark parts of a picture frame.

Edge LED lighting was also first introduced by Sony (September 2008) on the 40 inch BRAVIA KLV-40ZX1M (referred to as the ZX1 in Europe). The principal benefit of Edge-LED lighting for LCD televisions is the ability to build thinner housings (the BRAVIA KLV-40ZX1M is as thin as 9.9mm). Samsung has also introduced a range of Edge-LED lit LCD televisions with extremely thin housings.

LED-backlit LCD TVs are considered a more sustainable choice, with a longer life and better energy efficiency than plasmas and conventional LCD TVs.[6] Unlike CCFL backlights, LEDs also use no mercury in their manufacture. However, other elements such as gallium and arsenic are used in the manufacture of the LED emitters themselves, meaning there is some debate over whether they are a significantly better long term solution to the problem of TV disposal.

Because LEDs are able to be switched on and off more quickly than CCFL displays and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks (LEDs off) and a high brightness (LEDs on), however care

What is the best LED tv on the market?




Chris


i have been thinking about getting a new tv and have been told that Panasonic are the best to get, is that true? I am looking at approx 42" and have a good Hz rating. Any advice please?


Answer
Unfortunately, you were given the wrong information. Panasonic is better in making plasma tvs rather than led. Again, best is a very subjective term but when it comes to lcd-led tvs I prefer lg that's why I got my smart 3d tv from them. Before my purchase there were several factors I had to consider but I chose it because it's user friendly, I'm comfortable with its 3d and it didn't hurt my pocket that much.

My sony 3d led tv's got a long line of burn in on the left side, I tried to clean it with led screen cleaning solution but no luck. Is there any way that I can fix this?, thanks


Answer
What you have is dead pixel and not burn in. I have never had any luck buying any Sony products at all. I purchase a 32" CRT tv in the 90's and that only lasted less than 3 years, then the first HDTV in the market a 34" HDTV from Sony. That also did not last more than 3 years. 2 DVD players when they first came out model 7000 and 7700 both at over $1,100 each and that also did not last over 3 years. They do not have a very good customer service support, they will just refer you to an authorized repair shop. If you read yahoo questions, you can read many problems from other customer with Sony product problems. My first Plasma tv from Pioneer purchased in 2002 is still running. Also have 4 other Panasonic Plasma tv and no problems. First generation blu ray disc player from Panasonic which is now over 4 years old and played over 300 blu ray disc movies without any problems. You may try calling or email Sony and see what they say. Hope this will help you out.

What is the new Samsung LED TV about?




Tom


What is the new technology behind the samsung led tvs? Does the screen actually use LED to produce the picture? If so how much better is the quality?


Answer
sorry tvtech1 is off just a little bit.
LED LCD tv's are not OLED tv's.
there is only one in the consumer market, sony makes it and it is only 11 inches, larger models are expected probably in 5 years
this is the only difference between a regular LCD and a LED LCD
all LCD tv's prior would use a white fluorescent lamp for the backlight. the problem is there is one lamp and it has to be on all the time. the tv uses filters to create blacks and shades of whites and blacks. since the light is always on, this is why LCD tv's have a lower contrast ratio. it is very difficult to filter completely and depending on the quality of the filters, colors can blend and mash together.

on the new LED LCD tv's
instead of the white lamp backlight, there is a sheet of thousands of LED's behind the front screen which provides the backlight for the tv. since the tv can control each LED(there are red, blue, and green LED's) it can turn them on and off in sections which causes the higher contrast levels and more accurate colors over a regular LCD tv.
the LED LCD's are getting on par with plasma tv's in regards to the contrast and color accuracy

the only concern in the market right now is that LED's burn out inconsistently and since the tech is fairly new, it is unknown when this will start to happen, which will cause issues with the overall picture. will it happen in 3, 5, 7, 10 years. manufactures do not know at this time

Deacon Blu


LG, Samsung, Sharp, Sony, & Vizio are the only ones that I know of that make some kind of LED TV but they all use a different term when they mention the LED lighting.
Which is better?



Answer
Generally...the most expensive ones are the best!

Those are usually the backlit LED TVs(a.k.a. local dimming). They have the highest contrast ratios and best picture qualities! Edge lit LEDs have problems with back light uniformity and have lower contrast ratios!

Vizio's "TruLED" TVs are just their marketing words for backlit LED TVs! Their "RazorLED" TVs are their version of the Edge-lit LED TVs!

Basically...if the LED TV is super thin...it's an Edge-lit! If it's super expensive and not so thin...it's a back lit!
