What is the difference between LED and LCD TV?



What Is The Difference Between LED and LCD TV

A common decision pondered by many consumers when shopping for a TV is whether to buy an LCD or LED TV. However, strictly speaking they are both the same thing because an LED TV is still ‘classed’ as an LCD TV. This is because an LED TV is simply and LCD TV that uses LED lights to illuminate the LCD panel rather than fluorescent lamps which had been used prior to the introduction of LEDs. A more accurate term for describing them is LED-lit LCD TV, or simply LED LCD TV.

For your typical shopper this makes the whole LED or LCD TV argument an even more confusing affair. So why do many manufacturers categorise their TVs using the phrase LED TV?


The reason is two-fold, firstly it provides a simple way to differentiate between the two varieties of LCD technology. But also, upon the introduction of LED TVs, I’m sure that from a commercial point of view ‘LED TV’ was considered more of ‘catchy’ marketing phrase which would ultimately attract more consumers and result in more LED TVs being sold.

Anyway despite the phrase ‘LED TV’ being somewhat inaccurate, it is the term that has been widely adopted to describe an LCD TV that uses LED lighting to illuminate the display.

Unlike other ‘self-illuminating’ technologies such as OLED displays and plasma TVs where the display panel emits its own light, LCD and LED TVs require an additional light source to make the pixels of the LCD panel visible.What is an LCD backlight?

Before the introduction of the Samsung LED TV brand and its associated marketing campaign in 2009 which heavily influenced the use of ‘LED TV’ as a commonly used phrase, it is worth pointing out that TVs that used LED backlights had actually been in existence since the first Sony LED TV was released in 2004.


The Liquid Crystal Display which is used in LCD TVs is made up of a thin layer of liquid contained between two layers of glass. The liquid crystal layer is manipulated when an electric current is applied to it. In order to make the changes in the liquid crystal layer visible to the viewer, the panel is illuminated from behind and by a backlight.


Before the introduction of LED TVs, Cold Cathode Fluorescent Lamps (CCFL) was the sole method used for backlighting. The fluorescent lamps are situated horizontally behind the full width of the LCD panel. Where LED TVs differ is rather than using CCFLs they use LEDs to provide the backlight.

                                           
Types of Backlight

To complicate matters even further, the term LED TV is itself a rather broad phrase which encompasses many variations of LED TVs which employ different LED backlight technologies. There are two different types of LEDs which can be used in two different configurations, consequently this produces some distinctly differently results.

The two types of light emitting diodes used in LED TVs are white LEDs and RGB.
White LEDs actually produce a blue’ish light which is negated by using a sulphur coating to make it ‘whiter’, this results in a quality of light that is comparable to that produced by CCFLs.
RGB (red green blue) LEDs use all three primary colours to produce a broader spectrum of light in comparison to either CCFLs or white LEDs, which in turn improves the range of colors (gamut) produced by the LCD panel.

Because the LEDs are placed directly behind the LCD panel, the uniformity of the backlighting is improved in comparison to edge-lighting (see below), however it can introduce another problem known as blooming. This is when the light from a brightly lit LED zone unintentionally illuminates an adjacent dimmed area of screen covered by an adjacent zone. To the viewer a bright on-screen object can appear to have an unwanted glow around it. This backlight method can also use the RGB variety of LEDs which as explained above has a wider color gamut.Full Array LED TV with local dimming

This type of LED TV produces the best results. It involves the use of more complicated technology which also makes it the most expensive option.

Using this method the LEDs are placed in an array across the whole of the area directly behind the LCD panel. The LEDs are divided into zones which can be separately controlled so that they can be independently turned on or off. The number of LEDs and the size of the zones vary between different brands and screen sizes. This arrangement provides the ability to simultaneously increase or decrease the brightness in different areas of the display, this produces superior black levels and improved contrast.


Benefits of LED TV technology

Improved energy efficiency – Depending on which figures you believe, LED TVs are said to be 10-40% more efficient than standard LCD TVs. It is difficult to obtain an exact figure for this unless you compare a CCFL LCD with an equivalent LED TV model. Because LED TVs are more expensive they tend to have more advanced technical features such as auto-brightness and auto-power off which means they use less energy for reasons other than the improved efficiency gained from the LED backlighting itself.

Also some people would argue that the issue is overblown because the savings in electricity costs for a 60 inch LED TV in comparison to an equivalent CCFL LCD when uses for an average of 6 hours per day equates to less than $50 per year. Whilst it all helps to contribute towards reducing carbon emissions, it will take a good few years to recoup the extra investment required to own an LED TV compared to a standard LCD TV. However when comparing power consumption of LED TV vs plasma TV, LED TVs are the clear winners as they use half the power of an equivalent plasma TV.

Environment friendly – When the first Samsung LED TVs were released, as well as being more energy efficient it was claimed that the materials used in the manufacture process contained less harmful materials such as mercury. However one thing that we weren’t told is that LEDs contain other harmful materials such as arsenic and gallium.

Improved reliability – There can be no doubt that overall LED TVs are more reliable and durable than LCD TVs. The quoted lifespan of an LED TV is 100,000 hours which is approximately 50% longer than the figure for standard LCD TVs. However this equates to 11 years of continuous usage, or 30 years if used 8 hours per day making it more likely that another part of the television will fail before the LED backlighting does.

A more significant point than reliability is that CCFL backlights actually degrade in performance over time. The brightness of CCFLs as well as the whiteness of the light produced deteriorates the more the TV is used and the older the TV gets. This affects quality of the picture which may become noticeably duller before the LCD TV actually fails.

What is the difference between 3D Integrated and 3D ready?

3D TV
By adding a sense of picture depth and dimensionality, 3D TVs create a more engaging viewing experience that's similar to watching a 3D movie in a theater. Like 3D movies, 3D TV requires that each viewer wear special glasses to see the 3D effects. 3D TV requires the use of wireless "active shutter" glasses.

Whether a 3D TV uses LCD or plasma screen technology, all 3D TVs use a specially designed screen that can display two different versions of a video image by alternating the video frames at very high speed. 3D video is basically two full-resolution 1080p images, one for your left eye and one for your right. The shutter glasses' lenses darken and lighten rapidly in coordination with the screen's flashing images. The timing of the shutter glasses is wirelessly controlled by an "emitter" that is usually built into the TV. The system creates an immersive viewing experience. True 3D viewing also requires a 3D video source, like a 3D Blu-ray player playing a 3D movie.

Active shutter glassesTo see three-dimensional effects on a 3D TV screen, each viewer must wear a special type of 3D glasses called "shutter" glasses. Also called "active" glasses, these battery-powered liquid-crystal glasses are able to lighten or darken hundreds of times per second to alternately block out the left or right lens in coordination with the video frames flashing on screen. The lenses aren't displaying images, just switching between dark and clear. To anyone not wearing shutter glasses, a 3D TV picture will look blurry. Active glasses are far more technologically advanced than the disposable 3D glasses handed out in movie theaters.

What is OLED (Organic Light Emitting Diode)?

OLED (Organic Light Emitting Diode)

OLED is a display technology that can be used to create flat-panel TV TVs. An OLED panel employs a series of organic thin films placed between two transparent electrodes. An electric current causes these films to produce a bright light. A thin-film transistor layer contains the circuitry to turn each individual pixel on and off to form an image. The organic process is called electrophosphorescence, which means the display is self-illuminating, requiring no backlight. OLED panels are thinner and lighter than current plasma or LCD HDTVs, and have lower power consumption. Only small OLED screens are available at this time.

What does DLNA mean?


DLNA
DLNA, short for Digital Living Network Alliance, is a collaboration among more than 200 companies, including Sony, Panasonic, Samsung, Microsoft, Cisco, Denon and Yamaha. Their goal is to create products that connect to each other across your home network, regardless of manufacturer, so you can easily enjoy your digital and online content in any room.
While all DLNA-compliant devices are essentially guaranteed to work together, they may not be able to share all types of media. For example, a DLNA-certified TV may be able to display digital photos from a DLNA-certified media server, but not videos. See our article on streaming music, photos and videos from your computer to your TV for more info.

What does PIP (Picture-in-Picture) mean?


Picture-in-picture (PIP)
There are two flavors of picture-in-picture: 1-tuner PIP models require that you connect a VCR or other video component to provide the source for your second picture. 2-tuner PIP models have two built-in TV tuners, so you can watch two channels at once using only the TV.

What does 1080 24p mean on a HDTV?


24p (1080p)

1080p is a high-definition video format with resolution of 1920 x 1080 pixels. The "p" stands forprogressive scan, which means that each video frame is transmitted as a whole in a single sweep. The main advantage of 1080p TVs is that they can display all high-definition video formats withoutdownconverting, which sacrifices some picture detail.


1080p TVs display video at 60 frames per second, so this format is often referred to as 1080p60. The video on most Blu-ray discs is encoded at film's native rate of 24 frames per second, or 1080p24. For compatibility with most current 1080p TVs, high-definition players internally convert the 1080p24 video to 1080p60. By late 2007, many HDTVsincluded the ability to accept a 1080p24 signal directly. These TVs don't actually display video at 24 frames per second because that would cause visible flicker and motion stutter. The TV converts the video to 60 frames per second or whatever its native display rate is. The ideal situation would be to display 1080p24 at a multiple of 24 frames per second, like 72, 96, or 120 frames per second, to avoid the motion judder caused by 3-2 pulldown, which is required when converting 24-frames-per-second material to 60 frames per second.

Clear Motion Rate (CMR) vs Refresh Rate

Clear Motion Rate (CMR) vs Refresh Rate

Whether or not people understand the rationale behind the refresh rates of LCD monitors, they believe or think that higher refresh rates mean more clarity in pictures or sharpness of picture on the screen. The refresh rates of an LCD explain how many times an image is drawn on the monitor every second. We have TV’s with refresh rates of 60Hz, 120Hz and even 240Hz. So does it really mean that higher the refresh rates of a TV, the sharper or clearer it is? And now there is another term called Clear Motion Rate to confuse the consumers further. This is a recent term that has been introduced by electronics giant Samsung. There are not many who understand the difference between Clear Motion Rate and Refresh Rate, and this article attempts to explain this difference.

Refresh Rate (Hertz)
All display monitors need to be refreshed many number of times every second. This refresh rate is expressed in hertz, and the number implies that the image is redrawn that many times in a second. The old industry standard was 60 Hertz, but there has been advancement in technology and now it is common to have TV’s with refresh rates of 120Hz and even 240Hz. TV’s with higher refresh rates flicker much less than TV’s with low refresh rates; also, the images are often sharper and clearer with TV’s of higher refresh rate. The human eye cannot detect a blur as the image is redrawn too quickly. This difference is all the more visible in programs where objects move at a fast rate such as sports or car racing. However, with most TV companies switching over to 120Hz refresh rate, this motion blur has more or less been controlled.

Clear Motion Rate (CMR)
CMR or Clear Motion Rate is a new concept introduced by Samsung that measures the capacity of an LCD to display fast moving objects smoothly. While there was only the refresh rate that decided the smoothness of images in a fast paced program, Samsung’s CMR takes into account backlight technology and image processor speed in addition to the refresh rate to decide motion clarity. This motion clarity means that a viewer can clearly see the name of the player and his jersey number, even when he is moving at a high speed, during NFL matches.

What's the difference between HDTV and HDTV Ready?


HDTV (High-Definition Television)
Often mistakenly used as a generic description of all digital television, HDTV specifically refers to the highest-resolution formats of the 18 original DTV formats. Although there still isn't 100% agreement among manufacturers, retailers, journalists, etc., only 1,080-line interlaced (1080i) or 720-line progressive (720p) broadcasts are generally considered to be true HDTV. 1,080-line progressive (1080p) is not an official HD broadcast format, but it is found on high-definition Blu-ray discs and some satellite TV movie broadcasts. And 1080p is now an established standard for HDTV screens.

HDTV-Ready
The term used to describe TVs that could display digital high-definition TV formats only when connected to a separate HDTV tuner. These TVs generally had built-in tuners for receiving regular NTSC broadcasts, but not digital. An HDTV-ready TV could also be referred to as an "HDTV monitor."
