In Uganda today all entertainment shopping arcades are filled with what most refer to as Plasma and LCD screens; they seem to be the in thing these days both in people’s homes and entertainment centers.
But the puzzling Question is what the difference between plasma and LCD TVs is and which of the two is durable and cost effective considering Uganda’s cost of living.
Plasma and LCD technology — what's the difference?
Plasma and LCD panels may look similar in appearance, but the flat screen and thin profile differ. Plasma screens use 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 of electrical charge applied to the crystals. Each technology has its strengths and weaknesses, as you'll read below.
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 most. , hence plasma and LCD sets produce excellent pictures. Some 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 with advances like LED backlighting).
The ADVANTAGES of Plasma over LCD are:
The DISADVANTAGES of Plasma vs LCD include:
LCD television ADVANTAGES over Plasma include:
DISADVANTAGES of LCD vs Plasma televisions include:
|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.|
|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 far 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|
|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|
Which is better value for me right now: plasma or LCD?
If you're in the market for a large screen television — and we're talking 50 inches and above — then we'd suggest a plasma screen. LCDs can give you better resolution; plasma still has the edge in terms of picture quality. One other thing to lookout for, whether you opt for plasma or LCD, is an integrated HD digital tuner — some TVs still have analog tuners, which look pretty terrible on a large screen.
At the end of the day (17-inch to 42-inch 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.
There has also been a lot of debate surrounding use in bright environments versus dark, cinema-like conditions. The traditional wisdom is that LCD performs better during the day due to its backlighting system, and that plasma in a dark environment, as it uses a glass front. Nonetheless, products like the non-reflective Pioneer Kuro plasmas and LED-backlit LCD panels with their better blacks completely turn this logic on its head. That said, plasmas do generally perform better in the dark, and models with an anti-reflective coating — such as the new Panasonic plasmas — are the best all-rounders.
If you're a true high-def junkie who's keen to see every pixel of a 1080p source reproduced as is, then LCDs are seemingly the way to go. However, 1080p is quickly becoming the norm, with many LCDs now featuring 1920x1080-pixel resolutions. Budget LCDs and plasmas on the other hand feature either 1366x768 or even 1024x768 (720p) resolutions. If you're buying a screen 50 inches or larger, there's now no reason to get anything less than 1080p.
Despite the current HD buzz, there is still very little content available in 1080p — especially when compared to the infinite amount of SD content like TV programs and DVDs. At present, Blu-ray, and some HD downloads, are the only sources that can do 1080p, and free-to-air is only 1080i.
But it isn't all about the resolution — it's not the pixels, it's what you do with them. Most modern TVs, and even budget ones, will accept a 1080p input, and it depends on the quality of the scalar on-board as to how good a picture you'll get. The big names — Panasonic, Sony, Samsung and LG — usually have very good image processors that can resize the source content — whether it's a DVD, Blu-ray or FTA — to the resolution of your screen without a problem.
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.
Google has a giant target on its back. Microsoft has been on a spending and deal-making spree to grow Bing , recently signing a huge search deal with Yahoo. And with Bing starting to steal some market share from Google, it’s proving to be a formidable opponent. Oh, and now you can’t count out Facebook either, which justlaunched a new realtime search engine.
Google’s not taking any of this lying down. Secretly, they’ve been working on a new project: the next generation of Google Search. This isn’t just some minor upgrade, but an entire new infrastructure for the world’s largest search engine. In other words: it’s a new version of Google.http://www2.sandbox.google.com (This is for test you can use it to compare with the current one)
The project’s still under construction, but Google’s now confident enough in the new version of its search engine that it has released the development version for public consumption. While you won’t see too many differences immediately, let us assure you: it’s a completely upgraded Google search.
Google specifically states that its goal for the new version of Google Search is to improve its indexing speed, accuracy, size, and comprehensiveness. Here’s what they wrote:
“For the last several months, a large team of Googlers has been working on a secret project: a next-generation architecture for Google’s web search. It’s the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions. The new infrastructure sits “under the hood” of Google’s search engine, which means that most users won’t notice a difference in search results. But web developers and power searchers might notice a few differences, so we’re opening up a web developer preview to collect feedback.”

Timothy Berners-Lee born 8th June 1955 London, England, is among the famous people we have in the ICT World. Berners-lee invented the World Wide Web (WWW) making the first proposal for it in March 1989.
On 25 December 1990, with the help of Robert Cailliau and a young student staff at CERN (Conseil Européen pour la Recherche Nucleaire), he implemented the first successful communication between an HTTP client and server via the Internet. Berners-Lee background:
Tim Berners-Lee's mother and father were both mathematicians who were part of the team that programmed Manchester University's Mark I, the world's first commercial, stored program computer, sold by Ferranti Ltd. One day when he was in high school Berners-Lee found his dad writing a speech on computers for Basil de Ferranti. Father and son talked about how the human brain has a unique advantage over computers, since it can connect concepts that aren't already associated. For example, if you are walking and see a nice tree, you might think about how cool the park is under the trees, and then think of your backyard, and then decide to plant a tree for shade behind your house. Young Berners-Lee was left with a powerful impression of the potential for computers to be able to link any two pieces of previously unrelated information.
- 1969 to 1973: Attended Sheen Mount primary school and Emanuel School in London.
- 1973 to 1976: graduated from Queen's College at Oxford University with a 1st class degree in physics.
In 1977: worked for two years as a software engineer with Plessey Telecommunications on distributed systems, message relays, and bar coding.
He then joined D.G. Nash, where he developed a multi-tasking operating system and typesetting software for intelligent printers.
In 1980, joined CERN as a consultant, while at CERN he proposed a project based on the concept of hypertext, to facilitate sharing and updating information among researchers.
It was because CERN was so large and complex, with thousands of researchers and hundreds of systems, that Berners-Lee developed his first hypertext system to keep track of who worked on which project, what software was associated with which program, and which software ran on which computers. While there, he built a prototype system named ENQUIRE.
Berners-Lee named his first hypertext system Enquire, after an old book he found as a child in his parents house called Enquire Within upon Everything which provided a range of household tips and advice. The book fascinated young Tim with the suggestion that it magically contained the answer to any problem in the world. With the building of the Enquire system in 1980, and then the Web ten years later, Berners-Lee has pretty much successfully dedicated his life to making that childhood book real.
1981 to 1984: left CERN and worked at Image Computer Systems Ltd, in Bournemouth, England as Technical Design Lead, with responsibility for real-time, graphics, and communications software for an innovative software program that enabled older dot-matrix printers to print a wide range of advanced graphics.
In 1984, he returned to CERN as a follow. CERN was the largest Internet node in Europe, and Berners-Lee saw an opportunity to join hypertext with the Internet. He said “I just had to take the hypertext idea and connect it to the Transmission Control Protocol and domain name system ideas and — ta-da! — the World Wide Web."
In March 1989, he completed a project proposal for a system to communicate information among researchers in the CERN High Energy Physics department, intended to help those having problems sharing information across a wide range of different networks, computers, and countries. The project had two main goals:
In 1990, with the help of Robert Cailliau, produced a revision which was accepted by his manager, Mike Sendall. He used similar ideas to those underlying the ENQUIRE system to create the World Wide Web, for which he designed and built the first Web browser, which also functioned as an editor (WorldWideWeb, running on the NeXTSTEP operating system), and the first Web server (info.cern.ch), CERN HTTPd (short for HyperText Transfer Protocol daemon).
The first project Berners-Lee and Cailliau tackled was to put the CERN telephone book on the web site, making the project immediately useful and gaining it rapid acceptance. Some CERN staff started keeping one window open on their computer at all times just to access the telephone web page.
Since CERN had been connected to the ARPANET through the EUnet in 1990. In August, 1991, Tim posted a notice on the alt.hypertext newsgroup about where to download their web server and line mode browser, making it available around the world. Web servers started popping up around the globe almost immediately. An official Usenet 8 newsgroup called comp.infosystems.www was soon established to share info.
Berners-Lee then added support for the FTP protocol to the server, making a wide range of existing FTP directories and Usenet newsgroups immediately accessible through a web page. He also added a telnet server on info.cern.ch, making a simple line browser available to anyone with a telnet client. The first public demonstration of the web server was given at the Hypertext 91 conference. Development of this web server, which came to be called CERN httpd, would continue until July, 1996.
In 6 August 1991, the first Web site built was at CERN, and was first put on line. It provided an explanation of what the World Wide Web was, and how one could use a browser and set up a Web server.
In June 1992, CERN sent Berners-Lee on a three month trip through the United States. First he visited MIT's Laboratory for Computer Science, then went to an IETF conference in Boston, then visited Xerox-Parc in Palo Alto, California. At the end of this trip he visited a old friend Ted Nelson, then living on a houseboat in Sausalito. Interestingly, Nelson had experience with film making, Berners-Lee had experience working with lighting and audiovisual equipment in the amateur theater, and Tom Bruce, who developed the first PC web browser called Cello, also worked professionally as a stage manager in the theater.
In April 30, 1993, CERN provided a certification for web technology and program code move to public domain so that anyone could use and improve it.
In 1994, Berners-Lee founded the World Wide Web Consortium (W3C) at MIT. It comprised various companies that were willing to create standards and recommendations to improve the quality of the Web. Berners-Lee made his idea available freely, with no patent and no royalties due. The World Wide Web Consortium decided that its standards should be based on royalty-free technology, so that they could easily be adopted by anyone.
In 2001, Berners-Lee became a patron of the East Dorset Heritage Trust, having previously lived in Colehill in Wimborne, East Dorset, England.
In December 2004, he accepted a chair in Computer Science at the School of Electronics and Computer Science, University of Southampton, England, to work on his new project, the Semantic Web.
In June 2009, Prime Minister Gordon Brown announced Berners-Lee will work with the UK Government to help make data more open and accessible on the Web, building on the work of the Power of Information Task Force.
He was also one of the pioneer voices in favour of Net Neutrality,[and has expressed the view that ISPs should supply "connectivity with no strings attached", and should neither control nor monitor customers' browsing activities without their express consent.
I can’t wait to have a 10MB link in my house, be able to download 1GB file in 10mins, be able to call my sister in USA without a buffering signal.
I can’t wait to watch some of my favorite movie series like 24, Boston legal online with an HD quality online.
Just imagine with this marine cable you will be able to access your favorite sites that you know are really heavy and so annoying to download that you actually have to keep your self busy by either making a cup of coffee or take a bath for it/them to fully display. Sites like Youtube, omg, cnn, bbc will be accessed in less than a second.
Its true Africa is born again from the slow speeds. This has been made possible by 3 companies who have or still installing a marine cable across the Indian Ocean connecting East Africa to the rest of world through India.
First company; SEACOM launched its services in Africa on July 23, 2009.
It announced that its 1,28 Terabytes per second (Tb/s), 17,000 kilometers, submarine fiber optic cable system linking south and east Africa to global networks via India and Europe has been completed and commissioned.
The backhauls linking Johannesburg, Nairobi and Kampala with the coastal landing stations were established.
SEACOM assured unprecedented opportunities, at a fraction of the current cost (did you hear that? A fraction of today’s cost), as government, business leaders and citizens will be able to compete globally through a network as the platform to drive economic growth and enhance the quality of life across the continent.
Second company; EASSY (Eastern African Submarine cable System) is also in its final stages of completing the delivery of its marine cable to Africa. This project is funded by Eastern Telecom companies, governments and countries like South Africa , Mozambique , Madagascar , Tanzania , Kenya , Uganda , Burundi , Rwanda , Botswana , Somalia , Sudan , Mauritius , Zambia , Comoros Islands and Djibouti are driving the project. We hope to have it fully up and running in less than 10 months (almost mid 2010).
Third company, TEAMs (The East African Marine System) this was spearheaded by the government of Kenya to link the country to the rest of the world through a submarine fiber optic cable. This of course came as result of Kenya thinking South Africa wanted to control the EASSY link. So far the 1st phase has been completed as according to E-marine. This cable will be connecting East Africa to the rest of the world through U.A.E and the estimated deployment is 4900km.
By end of 2010, Africa will have over 100GB of bandwidth and that means we shall be in position to own at least 1mb in our offices, homes and again we will be that competitive when it comes to the online business. Let us all keep our fingers crossed because the best is yet to come.
