TV Viewing Distance and Screen Placement in the Home Theater

Filed under Computers

The optimal television screen size is directly correlated with the available viewing distance.  Conversely, there are other aspects as well that must be taken into account.

Viewing Distance: Is it just an affair of individual partiality?

Sit extremely near your big screen TV and you would be able to discern the image build-up structure – scanning lines or pixels forming the picture, consequently off-putting your attention and ruining your home theater experience. Nonetheless, stay excessively far away, and the impression will be gone.

The truth is that there are no scientific rules here. This doesn’t mean that there aren’t any principles that you need to adhere to when planning a huge screen purchase or a probable home theater room.

SMPTE Recommendations and the THX Certification standards:

The Society of Motion Pictures and Television Engineers (SMPTE) commends that the screen dimension for home theater use needs to fill a 30 degrees field of view – in the horizontal map – for the spectators. On the other hand, the perfect television viewing distance ought to be such that the screen width fills an angle of 30 degrees from the watching place.

This SMPTE principle is also similar to the THX certification guidelines in that these advise that the back line of seats has to have no less than a 26 degrees watching angle and while suggesting an optimum viewing angle of 36 degrees.

So How Does All This Translate In Practical Terms?

An overall rule for the TV watching distance based on the SMPTE and visual perception guidelines, is that the nearest TV watching distance between you and your big screen television should be limited to almost two times the screen width (more accurate 1.87 x screen width for a subtended angle of 30 degrees), while the farthest distance being barely five times the width of your screen.

On the contrary, it is also critical to comprehend that these maximum and minimum watching distances have to be seen in the light of the video signal definition.

A fully resolved HD television (1080i, 1920×1080) supports a nearer viewing distance than ordinary analog TV. While twofold the screen width will be the best television watching distance for a HDTV display, it will be a bit too close for typical TV; in the later case, a three times the screen width will be a superior pick.

When it speaking about the use of regular-size standard definition analog TVs in the home theater, i.e. around 36 / 40 diagonal, the most favorable watching distance range is between 8 feet and 12 feet. television sets tinier than 36-inches aren’t big enough to meet the requirements for Home Theater use as their smaller screen dimension would not impart the wanted impact on the watcher.

Vertical Angle of View & Screen Height:

For best possible viewing, the sight of the watcher needs to be leveled with the center of the screen.

Maximum vertical angle of view: In those home theater set-ups where this is not likely, the SMPTE principles advise that the maximum vertical angle quantified at the seated eye height from the front row center location to the top most section of the projected image should not surpass 35 degrees.

This does not stand for the best possible watching angle but rather the threshold beyond which the watcher would be exposed to an intensified neck strain.

Minimum angle of vision: While there do not appear to be any specialized SMPTE or THX guidelines in this respect, studies have presented that if the screen dimension occupies less than 15 degrees of the viewer’s vertical field of view, then that picture looks miniature.

Practical Points:

In a usual home theater set-up, you do not need to actually fret concerning neither the maximum vertical angle of view, nor concerning the tiniest vertical angle of vision for an effective movie theater experience.

If one were to adhere to the mentioned TV viewing distance of twofold the screen width (as additionally listed previously according to the SMPTE principle of 30 degrees horizontal field of vision), you would necessarily be obeying the smallest possible angle of vision. The grounds behind that is there is a preset relation between screen height and width in accordance to your home theater screen aspect ratio of either 16:9 or 4:3.

Keeping in mind that most home theater rooms are almost 10 feet (3m) high, the resulting vertical viewing angle is customary well within the maximum of 35 degrees detailed in the SMPTE principles, all you must do is solely remain within the double the screen width guideline for your viewing distance.

What Backlighting Is Best For An LCD HDTV?

Posted by 1BigCloset on June 8, 2009 – 11:39 pm
Filed under Computers

LCD is winning the race to be the dominant display technology for HDTV. The LCD screen on a LCD HDTV is a choosy light sifter. It does not diffuse light from itself but it carefully refines light going through the screen from behind. Nearly all HDTVs consist of either a particular slip of luminescent plastic or sidelighting with luminous lamps to supply the backlight. Both techniques are difficult to command.

Screen resolution is only of fourth significance as stated by professionals when buying an HDTV set. Backlighting is the key element to enhancement in contrast ratio and grayscale.

It is chief that an LCD system admits for fixing of the level of backlighting and preferably, accomplishes this function automatically to improve the contrast of the print. Also, a compact backlight degree would also reducedcut-rate the electricity use and expand bulb life, as the power consumption and bulb lifetime is precisely connected to the backlight level.

Another crucial thing in the scale of backlighting is the consideration of “blur”. Blur arises when there is fast motion in the programming such as sports. When the image transforms quickly, the pixels can lag in reaction. Operative backlight engineering can reduce this significantly by strobing the backlighting, so that the individual pixels do not stay on longer than needed.

Sidelighting

With sidelighting, the backlight is positioned in the end of the LCD panel, and to each side to construct panel elucidation. The most essential drawback is that the amount of light cannot be assorted locally, and sidelighting can seem to be distinctly. This fallouts in a poorer contrast pic.

Conventional Backlighting

Generally backlighting is accomplished with a solo layer of electroluminescent plastic. These panels could age still amendments in this section have reduced this trouble. It has a limited life of 3,000 to 5,000 hours.

LED Backlighting

LED backlighting uses a form of LEDs that could be directed separately to offer extremely good restrain. In this outline, a big amount of LEDs are aligned uniformly behind the screen. Brightness advancement in LEDs have invented them more practical for backlighting.
This system gives local fainting technology and could get 1,000,000:1 dynamic contrast ratio. Constant authentic black range are within reach by shutting down a pixel’s light basis. This could eliminate the grayish black print typical of many LCD HDTVs.

The problem with regular white LEDs is that their spectrum is not ideal for photographic recreation because they are basically blue LEDs with a yellow phosphor on top.

LED backlights are very much useful that other techniques and since the LED backlight consumer fewer power, fewer heat is generated, that have to be achieved with air conditioning. LED backlights deal a stretched in use period of more than 50,000 hours.

Engineering Concerns

The electrical engineering is simpler with LED backlights. Cold cathode fluorescent bulbs (CCF) call for great AC voltages (1,500 VAC) at start, and operating voltages of 700 VAC or more. An electroluminescent panel requires a voltage of around 100 VAC @ 400 Hertz.

LCD systems with LED backlighting employ low voltage DC, generally 12 or 24 VDC. This effects in a mini, easier, and more trustworthy system. LED backlit systems have to be properly ventilated or their execution could suffer. The LEDs create decreased heat than CCF bulbs, but the heat is very focused. Operating at high-level temperatures lowers down the LED life span and alters their light spectrum, while decreasing output brightness.

OLED

A brand new technology that you would be hearing about in the upcoming years is Organic LED (OLED). This technology has a entirely different backlight technology, it doesn’t need one. Because of this, they get much decreased power. And because there is no backlight, an OLED system has a huge viewing outlook than an LED system. An OLED display is much slender than an LCD display.

OLED display have before been used for some time in digicams, cell phones and other technologies with quite slight panels, because they are dreadfully power competent, which is extremely significant in portable technologies.

Summary

LCD HDTVs and monitors with LED bundle backlighting are now the way of preference because they exhibit better image attribute at the same time saving energy. The ability to locally manipulate light output is vital acquiring high contrast degrees.

Shopping for Flat Screen Televisions: Plasma vs LCD

Whether you are a extreme video user, a sports freak, a movie crazy, or simply someone who desires to rest on of the tv for a couple of hours each day, flat screen TVs could provide you with the greatest viewing incident. Before you go out and browse for a flat screen, it helps to know what you are going to buy.

What is Plasma and LCD Technology?

At first flash, LCD displays and plasma screens seem very much identical; though, both use utterly distinct technologies to display distinctive pics.

A plasma display panel is equipped of many pixel cells, all consisting a mixture of rare gases (generally neon and xenon). Electrodes charge the cells with exact electrical voltages to evoke these gases creating them to glow and create certain colors.

LCD (Liquid Crystal Display) consumes lots of crystals that are in a liquid that is in the middle of two glass panels. The crystals coils to get a specified sum of light, generated by a fluorescent light in the rear of the panels, over, developing the color you make out on the screen.

The Differences between Plasma and LCD

Picture, Brightness, and Color

On the entirety, both LCD examples and plasma screens carry great picture attribute. When viewing tvs in a shop, LCD tvs look as if more glowing. The reason for this is that in perfectly lighted surroundings the matte screen of a LCD mirrors little light and so it maintains lots of its brightness and hue. A plasma screen, on the other hand, frequently has a mirror like finale that can mirror lots of light than an LCD making it to come out dull. LCDs are recognized for their in focus photo and dazzling color that constructs visions that appear to be real. Plasmas, on the other hand, normally produce a larger stretch of colors and produce a warmer, more lifelike impression to them.

Resolution

LCD displays deal superior resolution than plasmas of the same size.

Viewing Angles

This points to how far away  you can look at the pic evidently. Between the two technologies there is not a great deal of dissimilarity with most LCDs claiming they have pretty bigger viewing viewpoint.

Computer Use

LCDs were initially intended for computer purposes and still have the gain when exhibiting static figures, data, etc. LCDs commonly hold a larger digit of pixels per square inch meaning that they show huge quantity of records more plainly.

Fast Moving Scenes

If sport or fast-action acts are a big element of your TV viewing then it might be good to watch at a plasma screen so you will be satisfied. Plasmas normally deal enhanced performance with swift moving pictures being exhibited finely and clearly.

Longevity

A lot of people express that LCDs go on longer than plasmas because vision color could wither over time. Some people say that LCDs aren’t a nice selection because the backlight can wear out (even though these can be altered on several models).

Screen Burn In

The burn in issue is where an vision that is shown for long periods of time is burned into the screen. Static images like channel logos, video game models, and illustration left paused on screen for lengthy periods of time could be stamped into the screen. LCD examples do not go through from burn in, still trapped or dull pixels could be an problem.

Power Consumption

If power consumption is a issue, especially nowadays that climate change is a foremost matter, choose an LCD panel. They use roughly 40% less energy because they employ fluorescent backlighting to generate an picture.

Size, Weight, Durability

LCDs weigh smaller than a alike sized plasma screen and they are as well more tough. Due to the frailty and weight of a plasma screen, it might be worth putting your plasma tv well fastened.

Plasma or LCD: What is best for me?

There is no correct or wrong when picking a flat screen panel. First you determine what you typically use your television for. Then you view where your tv would be put then what features do you want. Lastly, you ought to deal with price and what will best go with your finances. A quick look around the Internet would provide you lots of shopping comparison websites that exhibit purchasers the mart with the smallest value.

We beyond any doubt recommend you Samsung LN46B550 but if Samsung LN46B550 is not what you are looking for you should check Samsung PN58B550 also.

Why Buying A TV Online Is More Appealing

Buying a TV online is not that easy. Many buyers wonder if it is safe to purchase a TV on the net. After all, a TV is a big purchase and nearly all persons feel more safe shopping from a local shop that will be accountable if something is damaged. While this is entirely understandable, the truth is that shopping for a tv on the net can be simply as reliable as getting from a shop – as long as you do your homework. Top of all, paying online can save you many money.

The price advantage

The utmost advantage of buying online is the money you can store. I matched values at both on the web and shops and the outcomes are shocking: On one incident, I came upon a famous 42″ Panasonic Plasma television for $3,500 from a safe online dealer, while the similar TV charge a whopping $5,500 from a famed electronics market. Even with the $250 transportation charge, that is a savings of $1,750, or 31%. The money you set aside paying on the net can get a distant approach!

So what’s the trade off?

Particularly, you endure a open warranty for a good value. Whereas big electronics markets commonly retain especially obliging warrants (mostly from 15 – 30 days, no questions demanded), on the web stores with low values habitually do not permit product exchange. As an alternative, they take into account that defective products to be the maker’s problem.
So before you choose a market, these are the probes you should demand:

Are you buying from a site with high rating?

Grade made by purchasers just like you. This review is an ideal technique to view what sort of experience other online buyers have felt with a shop. I constantly recommend finding a merchandiser with positive critiques, even if it means spending a minor extra. Knowing the long file of impending worries concerned with purchasing from a negatively commented retailer, the extra money given at a honest store will not turn to waste!

What is the return policy?

The most open selection of all is to obtain an on the internet store that deals a 15 – 30 day phase in which to return a damaged tv free of charge. Yet, various shops, counting honest dealers such as Amazon.com, J&R Music World, and others, will not admit returns of tvs over a particular size, even if they are damaged. But since the top costs regularly go from markets that do not let returns, you handle a tradeoff between amount and accommodating warranties. If you pay for get from a store that does not tolerate bring backs and something goes incorrect with your goods, you will not be jammed with a busted television, but you will need to refer all problems to the manufacturer.

If the television could be refunded, will the seller arrange for transport? The most accommodating stores would coordinate, and pay for, the pickup and shipment of a deficient television if you contact them within the return cycle. If you are paying for big-screen plasma or LCD program, then this service can be valuable — arranging for the transportation of a large television can be a frustrating and costly course.

If you keep this advice, you’ll be capable to stumble on a reliable online dealer that could save you a generous quantity of money over what you’d give at your resident electronics market.

The Bottom Line
When paying on the web it is principal to be doubtful. Yet, you have to also keep in mind that there are loads of reliable dealer that will bestow you splendid service and a fantastic transaction on the television of your dreams!

We beyond any doubt recommend you Samsung LN46B550 but if Samsung LN46B550 is not what you are looking for you should check Samsung PN58B550 also.

720p And 1080i HDTV – Which Is Better?

Filed under Computers

Is 720p Vs 1080i worth being disturbed for? Yes and no. If you’re a consumer looking for a pristine TV you could happily ignore the 720p Vs 1080i debate because every last Television which is described as HDTV or HDTV Ready is obligatory to provide for both formats.

NOTE: You are supposed to be alert though that masses of TVs which provide for 1080i possess less than 1080 lines and so range the 1080 signal low. That’s not a big problem as even ranged behind 1080i is far upfront of a consistent NTSC signal. It is important to remember that more expensive HDTVs have a tendency to have improved scalers than inexpensive ones, so this may be an problem.

However, for reporters, it’s a ongoing concern. Must they announce 1080 lines of interlaced video or 720 lines of progressive scan? They can definitely broadcast two signals: one in every layout, but that will use up a huge piece of capacity and be heavily steep for dreadfully small collection.

To answer the query, it’s significant to understand the variance between 720p vs 1080i. A 720p signal is developed with 720 horizontal lines. Each one structure is shown in its entirety on the television screen for 1/30th of a second. This is known as progressive scan (for this reason it is the ‘p’). The attribute is same with seeing 30 photographic pictures a second on Tube.

A 1080i signal is built with 1080 horizontal lines but every one of the lines are not seen on the television all together. Preferably, they are interlaced (hence the ‘i’), ie each other line is flashed for 1/60th of a second and then the other lines are flashed for 1/60th of a second. Hence, the frame scale is still 30 frames per second, but each frame is broken into two areas, which your brain then bring together subconsciously.

Almost all of the time, interlacing performs good but for rapid moving fragments in the same manner with sports such as baseball and hockey, it could make troubles which manifest themselves as a ’stepping’ effect on the television screen. Progressive scan signals don’t experience this dilemma and as a result are better suited to sports.

ESPN states it like this: ‘Progressive scan technology gives better fragments for the rapid moving situation of sports TV.’ Plainly, with 104 mph fastballs in baseball and 120 mph hits on goal in hockey, the line-by-line root of progressive scan technology greatly captures the intrinsic quick act of sports. For ESPN, progressive scan technology brings complete signification.

What is the point? For us as clients, 720p Vs 1080i is not a problem worth worrying on, so you can calm down and focus on the whole of the new things on your list when you obtain your brand new HDTV.

We beyond any doubt recommend you Samsung LN40B650 but if Samsung LN40B650 is not what you are looking for you should check Samsung PN58B550 also.
