TV Alphabet Soup - Learn More About LCD, Plasma, DLP and HDTV
By Mike Singh

Because of advancements in science and technology, there has been a revolution in the world of television as well. This article is going to focus on the new world of television and get into brief details of LCD, Plasma, DLP and how they relate to the HDTV.

Digital Light Processing (DLP) is the only 100% digital display in the world today. DLP televisions use an optical semiconductor that works with fidelities impossible to achieve with analog systems. DLP projectors make use of microscopic mirrors placed in a matrix formation on a semiconductor chip called the Digital Micromirror Device (DMD). Each mirror contributes one pixel to the projected image. The higher the resolution, the greater is the number of mirrors needed. Some common DMD sizes are 800x600, 1024x768, and 1280x720. HDTV compatible projectors need a 1920x1080 matrix.

Liquid Crystal Display (LCD) creates images by streaming light through LCD glass panels. The three panels are typically red, green, and blue filters. These filters will permit or block light to pass through each pixel thereby creating the final image. LCD TVs have brighter colors and can easily substitute for computer monitors. Most LCD TVs are less than 32. LCD TVs come in both HDTV capable and non-capable.

Compared to LCD TVs, Plasma TVs offer more screen real estate. Plasma TVs are cheaper per square inch and have better black levels makes them ideal for people looking for a big-screen home-theater. Plasma TVs are not available below 37 screen size. Plasma TVs are either enhanced definition (EDTV) or high definition (HDTV). EDTV are cheaper and can display HDTV format but at lower quality. EDTV works at 480p resolution, same as DVDs. While EDTV will do justice to your DVD collection, it wont be very useful with HDTV formats.

While these different formats give good picture quality, that doesnt mean that every model of each one is compatible with HDTV. You must make sure that the set you are interested in is HDTV ready if you want to take advantage of the high definition TV signals that are now available. It would be a great disappointment to pay a high price for an LCD, DLP or plasma TV only to find out that it isnt HDTV capable. The better quality picture of these formats does make them better choices over CRT format TVs for HDTV programming.

Virtual Reality and Computerized Projection Video Conferences with Holographic Images

Virtual Reality and Computerized Projection Video Conferences with Holographic Images
By Lance Winslow

In the future there will be VR Virtual Reality meetings using computerized holographic projection, as these technologies are all currently available and becoming more robust and soon will be mass marketed. Give it 2-5 years and we will see some pretty wide spread use of these technologies. The first uses will be for entertainment; Virtual Lovers, Living Room 3D Gaming and meetings with fellow bloggers and Internet Friend.

The costs at first will not be cheap and the bandwidth requirements substantial so not everyone will have them right away. Call the challenge the "DBD" or Digital Bandwidth Divide. Well we will need the increased speeds for future holographic meetings, video on the go and all sorts of communication devices too. I have some ideas to be able to read the information much faster using shapes as symbols for words rather than one's and zero's.

My thoughts are to use the spaces between the frequency waves to create unique shapes, each shape could be one of 40,000 characters. Each character could be a whole sentence or a word, imagine the speed then? You could still have 26 letters, 22 currently used symbols.

The distance between each device would mean that only the intended reader could read it and the cold could not be broken, as it would have to be done in real "non-time" which is impossible. And then you could send streams of light waves as information at unbelievable speeds and still use the latest images on photons techniques to really scream the stream to a living room or Corporate Office near you?

I certainly hope this article is of interest and that is has propelled thought. The goal is simple; to help you in your quest to be the best in 2007. I thank you for reading my many articles on diverse subjects, which interest you.

What You Need To Know About DLP HDTVs

What You Need To Know About DLP HDTVs
By Jim Johnson

HDTV is definitely the wave of the future when it comes to television viewing technology. It appears that high definition television broadcasting will start to come into it's own this year and progressively become dominant in the next couple of years. What that means for you is a much sharper image, better sound, and in turn, an improved television viewing experience.

Ever since the advent of cable and satellite TV services, the march toward entirely digital TV signal broadcasting has been taking place. Because of the limitations of the older analog TV broadcasting methods, digital signals were just not practical, but now that other methods of transmitting the TV signal are in widespread use, the switchover to the digital TV age is in high gear. And that has paved the way for high definition television standards that can make the fuzzy, unclear TV pictures of yesterday a relic of the past.

Along with the march toward better signal broadcasting, TV hardware has been steadily improving as well, and now we actually have three main competing technologies for displaying the screen image, LCD (liquid crystal display), DLP (digital light processing), and plasma TVs. They all are available in much thinner configurations than TVs of yesteryear, because the old bulky CRT monitors that have been used for so many years are on their way out. They also are capable of producing a much sharper and more colorful picture than past televisions too, and that bodes well for HDTV compatibility.

DLP TVs are the most recent technology to become commonplace in the television display field, although the technology has actually been in place for a while now. DLPs can produce an incredibly bright and high contrast screen picture that is absolutely stunning when viewed in tandem with a HDTV signal. They are also available in increasingly larger sizes and the prices are dropping rapidly as this display format becomes more commonplace. In addition, they lend themselves to a wide range of uses and can be connected to almost any digital video source that you wish to use, even your home computer.

So if you haven't seen the beauty of a HDTV signal being displayed on a DLP monitor yet, do yourself a favor and visit a local electronics retailer to see it for yourself. You will be glad that you did!

LCD Projectors for Sale

LCD Projectors for Sale

Do you want to continue to be at the cutting edge of technology with high-end presentation products? Do you want to keep your audience glued to you and the vibrant graphics and clear characters of your presentation? Whether you are presenting to 10 or 10,000 people, there is bound to be an LCD projector that is perfect for you. Here is a simple guide on what to look for when you want to purchase one.

Resolution

The first consideration to look for when shopping for an LCD projector is resolution. Resolution is the number of light dots (called pixels) per square inch of the image produced. The higher the number of the pixels, the clearer and tighter your image will be. Also, if your LCD projector of choice is high in resolution, the image you can broadcast can be expanded to greater degrees. If your lecture or presentation is heavy on graphics and high quality color, or if you need to present to a large crowd, then you will need an LCD projector with high resolution.

Brightness

Since the image your LCD projector will broadcast is projected with a high-powered light bulb, you will also want to consider how bright a projection you will need. Again, the brighter the image you project, the farther away it can be seen. This is an important consideration for people thinking of presenting to large and small groups.

Price and other considerations

These projectors do not come cheap, so price is a major consideration. If your company is small, a desktop projector with resolution the size of your typical computer monitor should suffice. Also, be sure to check on compatibility issues. Is the projector you want compatible with your hardware? If it is not, you may wind up with a very expensive lamp. Finally, ask about user support. Does it come with a warranty? If it does, how long is the coverage? Is there a technical support hotline you can call if you have trouble with your projector? All these things will factor into getting an LCD projector that suits your needs.

HDTV, also known as High Definition Television, is the future of the DTV transition. This transmits pictures with high resolution, which is twice higher than the analog TV or DVDs. HDTV projector is a specialized device for displaying the HDTV.

Today, HDTV projectors are used in various areas. This includes entertainment, business presentations, seminars, and also for public display. HDTV projector can be an addition to your home theater system as the HDTV projector is equipped to receive the HDTV.

Basically, HDTV projectors come in three different forms; DLP (stands for digital light processing) HDTV projector, LCD (liquid crystal display) HDTV projector, and LCOS (liquid crystal on silicon) HDTV projector. Among the three types, the LCOS is the latest trend in HDTV display. The cost of a HDTV projector will fluctuate based on the type. On an average, a DLP HDTV projector will cost $2,000 and more. While an LCD HDTV projector will cost less than $2,000 and an LCOS HDTV projector will approximately cost $5,000 and more.

To meet the varying needs, HDTV projectors come in a wide variety of sizes, weights, and technical features. HDTV projectors can be availed with a contrast ratio ranging from 1500:1 to 8000:1. Commonly, HDTV comes in two formats; 1080i and 720p (where i stands for interlaced, and p stands for progressive.) But, the advanced HDTV projectors come with 1920x1080 internal resolutions. Thus, this type of projectors can display 1080i with maximum clarity and it will cost $20,000 and more. Mostly, the HDTV projectors are compact in size and are very easy to operate.

Different brands of HDTV projectors are available in the market today. Some of the top brands are Sony, Mitsubishi, Dukane, Sharp, and Panasonic. Mostly, all the types and brands of the HDTV projectors are complemented with different warranty periods, A/V cables, remote control, and more. Depending on the availability, the HDTV projectors can be availed from dealers, local outlets, or online stores.

While purchasing a HDTV projector, it is always recommended to check the projector?s compatibility with other systems in the house like VCRs, DVD players, surrounding sound components and standard TV systems. If this is done, the HDTV projector will display pictures with high resolution, thus giving you a cinematic ambience and feel.

DLP Projectors

DLP Projectors
By Elizabeth Morgan

Some of the indispensable parts of a projector are the feed spool, xenon arc lamp, projection lens, optical sound head, take up spool, an aperture, normal lens and a rotating shutter. But with the advancement of science, new technologies have come into play. The projectors have become much more advanced in terms of clarity of picture and the quality of the pixels. Also, the projectors have found use in everyday households, as new versions of domestic projectors have arrived on the market. The abundance of LCD projectors, DLP projectors and video projectors has allowed the common man to enjoy the experience of a big theater hall in his living room.

DLP, or Digital Light Processing, is a technology implemented in todays projectors and projection televisions. In DLP projectors, the image is created by microscopically small mirrors. These minute pieces are then put in a matrix on a semiconductor chip. This chip is called DMD (Digital Micromirror Device). These mirrors are treated as pixels. The number of those minutely small mirrors exactly corresponds with the resolution of the project image.

There are single-chip projectors and three-chip projectors. A single-chip projector has a single DMD, and a single color wheel produces all the colors. The color wheel is divided into four sectors of basic primary colors. They are red, green, and blue, and an additional clear section to boost brightness. A three-chip DLP projector uses a prism to split light from the lamp. Then the basic colors are routed to their own DMD chip. Then these colors are passed through the lens, where they are combined together.
