Im sure siko peke yangu ambaye najiskia kuchanganyikiwa na kizunguzungu nikiingia kwenye maduka ya TV.Its so hard to decide what to buy. Kuna mtu aliniambia TV iliyoandikwa HD ready sio HD TV na mwingine aliniambia 'hizo ni lugha za masoko tu, ni kitu hicho hicho', mwingine akaniambia HD TV ni lugha inayotumika Marekani lakini in Europe wanatumia lugha ya HD Ready. Halafu LCD na PLASMA zinaonekana kuwa kama kitu kimoja lakini kwa nini wanatofautisha majina? High Def zina picture quality effect zikitumika bongo?
Kuna mtu ana experience na hivi vitu vyote?

Aisee jamaa kanifurahisha sana hapo juu, na wewe hapa ulivyomwuliza with the greatest of innocence.....i like it.

OK. HDTV ni kwamba HD (High Definition) has tuner built in, and HD-Ready means you need to buy an additional external tuner. HD-ready should be cheaper than HDTV.

Plasma against LCD, hapa kweli, tofauti ya quality ni ngumu kuona. Experience yangu huwa nikishauza pamba, huwa naingia dukani na kujifanya nanunua na kukaa naangalia TV au Skysports kwa kama saa nzima LOL....utamu unanichanganyaga mwanawane, naona nisevu vijisenti vyangu nikachonge mtumbwi nianze biashara ya mapanki kule kwetu lol.

Ok I can break down like this brother.
Kuna analogy TV brodcasting na digital TV broadcating.
Nchi nyingi duniani zimeanza kutumia digital TV (DTV)broadcasting system kwa kuwa inasafirisha picture& sound (TV)signal with high quality (less distorted) compare to analogy TV broadcasting.

Na hii digital TV broadcasting imegawanyika ktk :
SDTV na HDTV (High Defination TV) ambapo HDTV ni bomba zaidi ya SDTV.
Hii ni njia tu za kusafirisha TV signal kutoka TV station mpaka nyumbani kwako imeongelewa hapa.

Sasa nakuja kwenye TV set unayotumia kutizamia picha ambayo ili capture digital signal lazima Tv set iwe compatible .
i.An HDTV-ready set, also called an HDTV monitor, which does not have an HDTV tuner. HDTV-ready sets often have NTSC tuners, so you can still watch analog TV with them. This is the option for you if you want to have HDTV capabilities later on but aren't ready for the financial commitment now. Your picture quality will still be better than on your old TV, but it won't be high definition until you get an HDTV receiver

ii.An integrated HDTV, which has a digital tuner, also known as an ATSC tuner, built in. If a station near you is broadcasting in HDTV, you can attach an antenna to an integrated set and watch the station in high definition.
Pia kuna ESDTV set hii ni nzuri ila not compatible na HDTV it compatible with SDTV.(Ziko nyingi za Plasma pia ndio uzuri wake)

Sasa hapa hapa tumefika sehemu kuwa TV signal inayotumwa na TV station iko bomba,TV set iko compatable nayo inapokea vema.Kilichobaki kuwa je ina display vizuri pia.
Best diplay inategemeana na display technogy ya monitor yako(diplay unit)Display technogy zilizopo ni CRT,TFT,LCD ,PLASMA na katika hizi PLASMA ndio bomba ktk misingi ya pixel picha bomba!Also plasma TV is so named because its picture is created by plasma that causes phosphors to glow in different colors, resulting in a picture with high brightness and contrast. Unlike LCDs and CRTs, plasmas are not limited to a certain size. So your screen can be as big as you like -- assuming you have the room and the funds.

Mwisho ni kwamba ukiwa Tv Station wana digital TV transmition ya HDTV na wewe una Integrated HDTV display ya PLASMA basi hapo unapata high defination picture ya kweli.
Vinginevyo ni sawa na kuwa FM radio bomba ila speaker ovyo,au speaker nzuri radio hainasi vema mawibi ama ni AM noise nyingi.
 
LCD vs. Plasma: which TV is right for you?
Take a look at our table to find out how plasma and LCD TVs compare when measured up against each other in different categories. Remember - technology changes all the time, with both plasma and LCD TVs improving in quality, so use this table as a guideline only:

Plasma LCD
Size and weight Generally larger than LCDs, with screens up to 71 inches. Plasma TVs are usually around 10% heavier than LCD screens (meaning great care should be taken when mounting on a wall) Usually no larger than 46 inches, though larger TVs are in development. LCDs are often slightly thinner than plasma TVs.
Quality of Picture Usually plasma screens have better contrast. Both have excellent quality and sharpness. LCD usually has a slightly clearer picture in smaller models and a higher resolution.
"Image Burn" Nowhere near as much of a problem now as a few years ago, there is still a slight concern that images left still for a long time could be etched into the screen. This is not a problem with LCD screens.
Viewing angle Plasma tends to have slightly better viewing angles than LCD. Some models have a restricted viewing angle, but many allow up to 160-degree
Brightness and glare In a fully dark room, plasma TVs have better contrast and brightness than LCD screens. LCD TVs generally reflect less light and glare, so fare better in normal light conditions
Lifespan Usually, plasma screens last for up to 60,000 hours before they dim by half. LCD TVs usually last 60,000 hours or more before they dim by a half.
Energy usage Plasma uses slightly more power than LCD screens. LCD TVs often use less power than plasma screens. They can consume 60% less power than a CRT television.

Plasma vs. LCD...
Now that you have read about the main differences between plasma and LCD TVs you may have decided which one is right for you. They both have stunning, clear pictures and most models offer amazing widescreen viewing - so you can't go far wrong with either! However, it's worth considering where you are going to watch your TV and for what main purpose you will use it. If you are looking for a smaller screen to put in a TV, bedroom or small living room - LCD is probably your best bet. If you're looking for a home cinema screen, then a larger plasma model may be the one for you.

The material are good mwanatanu!

But it should be known that Plasma is the best whether the screen size is large all small.Although the difference is crystal clear with big screen.
 
1. Plasma and LCD - what's the difference? | 2. Picture quality | 3. Plasma's advantages over LCD | 4. LCD's advantages over plasma | 5. Which is better value? | 6. Do I need to buy 1080p?


1. Plasma and LCD technology - what's the difference?
Plasma and LCD panels may look similar, but the flat screen and thin profile is where the similarities end. Plasma screens, as its name suggests, uses a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens (liquid crystal display) are in layman's terms sandwiches made up of liquid crystal pushed in the space between two glass plates. Images are created by varying the amount electrical charge applied to the crystals. Each technology has its strengths and weaknesses, as you'll read below.

2. Is there a difference in picture quality between plasma and LCD screens and normal CRT TVs?
It's not what's happening behind the screen that's important - it's how the screen performs as a television that matters the most. In that regard, both plasma and LCD sets produce excellent pictures, although many home entertainment specialists and gamers still say CRTs produce the best overall images (although the latest plasmas are particularly good, and LCD sets are quickly catching up in terms of quality).


Those same home entertainment specialists will tell you that for basic home theatre-like usage, plasma screens have a slight edge over LCDs. This is because plasma screens can display blacks more accurately than LCDs can, which means better contrast and detail in dark-coloured television or movie scenes. The nature of LCD technology, where a backlight shines through the LCD layer, means it's hard for it to achieve true blacks because there's always some light leakage from between pixels. This is steadily improving with every new generation of LCD, however.

3. What advantages does plasma have over LCD?
Apart from better contrast due to its ability to show deeper blacks, plasma screens typically have better viewing angles than LCD. Viewing angles are how far you can sit on either side of a screen before the picture's quality is affected. You tend to see some brightness and colour shift when you're on too far of an angle with LCDs, while a plasma's picture remains fairly solid. This is steadily changing, however, with more and more LCDs entering the market with viewing angles equal to or greater than some plasmas. Plasmas can also produce a brighter colour, once again due to light leakage on an LCD affecting its colour saturation.



Plasma pundits will also tell you that some LCD screens have a tendency to blur images, particularly during fast moving scenes in movies or in sports. While that was true for older generation LCD screens, newer models have improved significantly -- so much so that the differences in performance between LCDs and plasmas in this regard is almost negligible (here's a tip -- if you're shopping for LCDs, check the pixel response time, measured in ms. The lower it is, the better the image quality in fast moving scenes).

A new 42" plasma from Hitachi


Traditionally, the biggest advantage plasmas have had over their LCD cousins is price, particularly in the large screen end of the market. In the past 12 months, this has changed, with LCDs matching or even beating plasmas in both resolution and price. Plasmas being sold in Australia generally run between 42-inches and 63-inches wide, with the cheapest standard definition 42-inch selling for approximately AU$2,300 (although you can expect to find sets cheaper than AU$2,000 in real world prices). 60-inch and above plasmas can go for as much as $25,000.

LCDs, on the other hand, generally top out around the 52-inch mark -- though there is now a ludicrously expensive 70-inch Sony available -- but are incredibly competitive with similar-sized plasmas. In the six months since we last updated this feature, prices of the replacements of two flagship TVs have dropped by a third. Sony's high end 52-inch KDL52W3100 LCD, for example, retails for AU$6,799 (down from AU$9,999), while Pioneer's top of the line 50-inch PDP-LX508A plasma goes for AU$$7,999 (down from AU$10,999).

4. What advantages does LCD have over plasma?
Apart from being price competitive, LCD has the edge over plasma in several other key areas. LCDs tend to have higher native resolution than plasmas of similar size, which means more pixels on a screen.


LCDs also tend to consume less power than plasma screens, with some estimates ranging that power saving at up to 30 per cent less than plasma. LCDs are also generally lighter than similar sized plasmas, making it easier to move around or wall mount.


LCD pundits also point to the fact that LCDs have a longer lifespan than plasma screens. This was true of earlier plasma models, which would lose half of their brightness after more than 20,000 hours of viewing. Later plasma generations have bumped that up to anything between 30,000 and 60,000 hours. LCDs, on the other hand, are guaranteed for 60,000 hours.

You might have also heard that plasmas suffer from screen burn in, an affliction not as commonly associated with LCDs. Screen burn in occurs when an image is left too long on a screen, resulting in a ghost of that image burned in permanently. Newer plasmas are less susceptible to this thanks to improved technology and features such as screen savers, but burn-in is still a problem. But after a few days of use most burnt-in images will fade -- they are no longer permanent.

5. Which is better value for me right now: plasma or LCD?
If you're in the market for a big screen television -- and we're talking 50-inches and above -- then we'd suggest plasma as a safe bet. Plasmas give you more bang for your buck at the big end of town, and while LCDs can give you better resolution, plasma still has the edge in terms of picture quality. One other thing to look for, whether you opt for plasma or LCD, is an integrated tuner -- many TVs still have analogue tuners, which look pretty terrible on a large screen. Try to get a model with an inbuilt HD tuner if you can.

At the smaller end of things (15" to 42" TVs), LCD is the only way to go if you want something slim and tasteful. And the best thing is that LCDs are getting cheaper all the time.

6. Do I need to buy 1080p?
If you're a true high-def junkie who's keen to see every pixel of a high-res 1080i/p image reproduced pixel-by-pixel (providing you have a source that high, of course), then LCDs are seemingly the way to go. However, top-of-the line plasmas will also display 1080p content, so the choice isn't as easy as it once was.
Despite the current HD buzz, there is still very little content available in 1080p -- especially compared to the infinite amount of SD content like TV programs and DVDs. Though buying 1080p now may mean you get some degree of futureproofing, you may not be getting the best picture. It's not all about the resolution. For example, one of the best TVs we've seen yet is only 720p (HD) compliant -- the Pioneer PDP-508XDA -- and yet 1080p content still looks better on it than on any LCD you could name. Unless you measure your screen size in metres, 1368 x 768 resolution could still be enough for your needs.

To be little more precise and to add a caution...

An HDTV is a television that is designed to receive and properly display television signals in either of the two ATSC (Advanced Television Systems Committee) broadcast formats: 720p and 1080i. The native resolution of the television should be either 1080 pixels or 720 pixels, but it might be lower in cheap sets (e.g., 480). A television with a native resolution of 1080 will upsample and interlace a 720p signal. One with a native resolution of 720 will downsample and deinterlace a 1080i signal. An HD-compatible television with a resolution of 480 will need to downsample both 720 and 1080 pictures.

An HD-ready television is... a television. The term "HD-ready" means absolutely nothing in terms of television capabilities, although it certainly implies something better than the norm. Some manufacturers may produce a high-resolution television without an HDTV tuner, while some might label their run-of-the-mill television HD-ready because you can connect the output of an HDTV tuner to their inputs. This presents a problem to unwary consumers, who may not be aware that the television they buy has no special HD features.

This kind of labelling is all too common, unfortunately, and misleads many consumers. When digital music - the CD - first appeared, many companies branded their amplifiers and speakers as "digital ready". These products seemed to offer something special, but nothing had changed except for the word "digital" on the label. Today you see photography equipment branded in the same fashion. A "digital tripod" is a normal camera tripod with the word "digital" added - it does nothing special to earn that moniker.
 
Plasma vs LCD

The ADVANTAGES of Plasma over LCD are:

1. Larger screen size availability.

2. Better contrast ratio and ability to render deeper blacks.

3. Better color accuracy and saturation.

4. Better motion tracking (little or no motion lag in fast moving images).

The DISADVANTAGES of Plasma vs LCD include:

1. Plasma TVs are more susceptible to burn-in of static images.

2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images.

3. Does not perform as well at higher altitudes.

4. Shorter display life span (about 30,000 hours or 8 hrs of viewing a day for 9 years) than LCD. This can vary according to other environmental and use factors.

LCD television ADVANTAGES over Plasma include:

1. No burn-in of static images.

2. Cooler running temperature.

3. No high altitude use issues.

4. Increased image brightness over Plasma.

5. Longer display life (about 60,000 hours - at which time all you may need to do is replace the light source, not the entire set). This can vary according other environmental and use factors.

DISADVANTAGES of LCD vs Plasma televisions include:

1. Lower contrast ratio, not as good rendering deep blacks.

2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts).

3. Not as available in large screen sizes above 37-inches

4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you.

5. LCD televisions are much more expensive than equivalent-sized Plasma televisions
