How Does HDTV Work?

In the world of HD television, there are two basic choices: those that include a digital tuner (HDTVs), and those that use a separate digital tuner (HD monitors). HD monitors and HD televisions offer the highest level of digital TV performance—about five times more picture detail than analogue.

A digital TV will have a much greater resolution than its analogue counterpart. Almost all digital TVs can display progressive-scan DVDs (480p) and HDTV (usually 1080i) at full resolution, whereas analogue cannot. With a digital TV, you’ll enjoy superior picture and sound quality, giving you the best home entertainment experience.

Broadcasting

On an analogue TV, the quality of your reception is directly related to the quality of the signal. With digital broadcasting signals, audio and image quality remain consistent, no matter how strong or weak the signal.

Image Rendering

Both old and new TV displays are made up of a series of horizontal lines which are in turn, comprised of tiny dots called pixels. The number of these lines and dots makes up what is called "resolution." HDTVs have significantly higher resolution than standard analogue TVs.

LCD TV FAQ

What Is Intelligent Sensor?

LG Intelligent Sensor technology evaluates ambient light conditions in the room and automatically adjusts brightness, contrast, and colour balance to optimise picture quality, reduce eye strain, and save money on your energy bill.

What Is SRS WOW and How Does it Work?

SRS WOW is a combination of SRS® Sound, SRS TruBass® and SRS FOCUS® audio technologies.

SRS® Sound restores the spatial information masked by traditional recording and playback techniques. By breaking down the stereo signal into its various components, SRS restores the spatial cues and ambient information present in the audio signal, placing them in the proper space relative to the direct sounds for a true surround-sound experience.

SRS TruBass® is a patented SRS technology that enhances bass performance by utilising proprietary psychoacoustic techniques. These techniques restore the perception of fundamental low-frequency tones by utilising the harmonics present in the original audio source to recreate the bass frequency information—even if this information is below the speaker or headphones low-frequency limitations.

SRS FOCUS® elevates the sound image field to create the perception of image height. When used in combination with SRS 3D, FOCUS delivers an enlarged sound image, producing a much taller and wider sound field with a broad sweet spot.

What Are the Benefits of SRS TruSurround XT?

SRS TruSurround XT carefully places content in the correct location, paying special attention to the center channel dialogue placement.

It also:

• Provides a wider and more dynamic sound stage.
• Improves the listening experience with added bass.
• Creates a broad sweet spot for a realistic audio experience.
• Instantly improves the surround-sound listening experience for the majority of consumers who do not have 5.1 speaker systems.
• Works great in any room no matter what the furniture configuration.

What Is “Viewing Angle” and Why Does It Matter?

With LCD TVs, the viewing angle is the angle at which a screen can be viewed without experiencing deterioration of image quality, specifically in terms of brightness and contrast ratio. A wider viewing angle means that you can experience perfect picture from more places in the room.

What Is Aspect Ratio?

Aspect ratio refers to the shape of a screen, comparing the horizontal dimensions to the vertical dimensions. A widescreen LCD display has an aspect ratio of 16:9, whereas a traditional screen has an aspect ratio of 4:3.

What Is Contrast Ratio?

Contrast ratio is a measurement of the difference between a screen's darker colours and its lighter colours. A higher contrast ratio means a wider range of colours.

Why Is Brightness Important?

The brightness of a LCD TV is measured in cd/m2. Simply put, the higher the number, the brighter the images on the screen. And, the brighter the picture, the better the viewing experience.

The LG Design Philosophy for TVs

Design plays a critical role in harmonising technology and human needs. In an effort to predict emerging needs and deliver innovative products to the public, LG has developed a comprehensive design philosophy that boils down to four basic elements: concept, style, interface, and finish.

LG’s Digital Display Innovations

At LG, we design our digital displays with our customers in mind, introducing new products that demonstrate a clear commitment to our core design principles. Broad knowledge and an ongoing commitment to developing next-generation digital display technologies are two of our key advantages over competitors. We are constantly pushing the envelope with innovative designs for LCD and Plasma TVs. For example, in 2008 we launched Scarlet, the world’s slimmest LCD TV at just 44.7mm thick. And we will continue to invest in the next-generation technologies that are redefining our entertainment expectations for the future, such as flexible displays and 3D displays.

LCD TVs

LG LCD TVs are some of the most advanced in the industry. Our LCD TVs can take low-resolution analogue signals to near high-definition levels. They also incorporate 100Hz scanning-technology, doubling the refresh rate and allowing viewers to watch fast-moving action sequences without motion blur. Intelligent Sensor technology optimises brightness and contrast by adapting to the ambient light conditions in the room. Last but not least, LG speaker design provides clear and powerful sound at any volume, for an exhilarating audio experience every time.

Plasma TVs

LG Plasma TVs deliver startling clarity and unprecedented detail, with deeper blacks and superior shadow detail. Our Dual XD Engine produces clear, crisp picture quality, which is further enhanced by a super-bright panel design.

Plasma or LCD? Which is Right for Me?

LCD TVs and Plasma TVs are both sleek, thin, state-of-the-art, and capable of displaying stunning, high-definition picture and sound. But which technology is right for you?

What Is a Plasma Display?

Plasma displays are flat panel TVs that use conductive plasma to produce coloured light. Gas in the plasma state reacts with phosphors in each sub-pixel, to produce vivid colours and ultra-clear picture.

Plasma displays generate their own light to produce a stunning contrast ratio and smoother, crisper, high-motion video. This is one reason why some consumers prefer plasma displays to LCD TVs for watching sports and action movies. Plasma displays are also known for their deep, rich blacks, and incredibly precise colours, making them ideal for watching films—where dark scenes are more common.

For several reasons, many experts consider plasma displays the better choice for home cinema environments. First, plasma displays tend to perform better in light-controlled environments, such as home cinema rooms. Second, plasma displays have a slightly wider viewing angle than LCD TVs, so no matter where you’re sitting in the room, you can still enjoy a precise, vivid picture.

What Is an LCD Display?

LCD displays are digital televisions with a fixed pixel structure. Each pixel has three sub-pixels of red, green, and blue. The image on a flat panel LCD display is generated by a backlight behind the panel. The image goes through a polarising filter and each sub-pixel has tiny crystals that create different levels of brightness.

One advantage of LCD TVs is the wide range of sizes—they start at 15” and go up to 55”. Smaller LCD TVs are offered in both 4:3 and widescreen versions.

LCD displays also offer a great deal of versatility. Their wide size-range allows for a wide price-range, making it easier to find one to fit your budget. Also, since LCD TVs use adjustable backlight technology, the picture won’t wash out in brighter rooms or environments where light conditions can’t be controlled. LCD TVs are also specially designed to perform wonders for video games and computer graphics.

Why Should I Get HDTV?

There are many reasons to get HDTV, from stunning picture quality, to enhanced programming, to HD sound—not to mention the upcoming national transition to digital.

Picture Quality

Are you invested in the quality of your home entertainment? With HDTV, you’ll enjoy richer colour, deeper blacks, and sharper images when watching your favourite programmes, films, and sports.

Resolution

Both old and new TVs are made up of a series of horizontal lines, which are comprised of tiny dots, called pixels. The number of these lines and dots make up a TV’s "resolution," or picture clarity.

Widescreen

Bring home a bigger, better picture, and cinema-style viewing, with a widescreen TV. In 16:9 format, you’ll enjoy "true" widescreen television and films. Digital widescreen is the future of TV.

Surround Sound

Many high-definition TV programmes are broadcast in Dolby Digital 5.1 Surround Sound—the same high-fidelity audio found in movie theaters. With an HDTV, you’ll enjoy cinema-quality surround sound in the comfort of your own home.

HDTV: The Future of TV

In the new digital era, broadcasters will offer HD resolution over-the-air, including HD-quality picture and cinema-quality sound that far surpasses the picture and audio quality of the current system.

Networks will continue to broadcast in multiple resolution-formats for some time but, as more and more HD programming becomes available, there will never be shortage of breathtaking digital entertainment for your new HDTV.

Plasma to Fit Every Lifestyle

LG Plasma TVs provide the ultimate viewing experience, with sizes ranging from 42" to 60".

Important Things to Know:

• High-Definition refers to resolution—the number of horizontal lines that can be displayed on the screen—not the technology upon which the TV is based.

• Virtually all TV stations are now broadcasting digitally, with analogue broadcasts expected to end between now and 2012 (depending on the region). To aid in the transition, manufacturers and service providers are producing reasonably priced converters, so that analogue TVs can continue to receive over-the-air signals, even after analogue is a thing of the past. Nonetheless, upgrading to a digital TV is the only way you’ll be able to experience the great benefits of digital broadcasts (such as theater-quality sound and HD picture quality).

• Digital cable is not necessarily HDTV. This is a common misconception. Digital cable is usually analogue-grade television that’s been digitised and sent, via cable, as a digital signal. Digital cable’s picture and audio quality is superior to standard analogue cable, but it is still inferior to breathtaking HD picture and audio.

What Is the Difference Between a Digital TV and an HDTV?

Digital TV

Televisions (the combination of a display and a receiver) in the digital world are known as Digital TVs (DTVs). Digital television eliminates snow, ghosts, and interference, among other benefits.

HDTV

TVs that receive digital TV broadcasts of 720 or more progressive lines (rows of pixels, as measured vertically), are called High-Definition TVs, or HDTVs. High-Definition TV encompasses the following screen resolutions: 720p, 1080i, and 1080p. HDTV is the fastest-growing segment of the digital TV (DTV) market—delivering breathtaking pictures and sound.
