LCD stands for Liquid Crystal Display. This type of TV gives wonderful clarity and high brightness and contrast levels. They are slim, elegantly designed and awesome to look; they definitely décor the home interiors.

Taking care of LCD TVs is a very important aspect. Since they are also expensive when compared to the CRT TVs, they have to be taken special care, in order to keep it cost effective and economical. There are various factors that determine the care of it like the humidity or the temperature of the place, other environmental conditions, the way the TV is handled and used etc. It is an electronic equipment which is very sensitive in nature, and so few things have to be taken care of.

The first and foremost thing to remember is that the TV should be used at room humidity and temperature for it to perform well. If the TV is used in high temperatures or humidity, then the performance can be highly affected. When the temperature is less than 10oC, then it should not be used, as it can cause the brightness levels to reduce, thus decreasing the performance. Also, exposing the TV to a drastic difference in temperatures can also affect the polarizers’ performance. For example, if the TV is exposed to a drastic change in the temperature from cold to hot, if might form dew drops to get accumulated over the TV which can prove hazardous to the polarizers’ life.

The environmental factors also have to be considered while having an LCD TV. It is always recommended to keep the TV in a clean and dry place, away from dust and other liquids. When the TV comes in contact with excess dust, it can result in the malfunctioning of the electrical parts inside the TV due to electrical shorts. Also, if the TV is exposed to liquid or humidity, the polarizer can get discoloured, resulting in the TV not functioning properly. Liquids or humidity should also not be allowed to enter inside the TV, in order to prevent corrosion of the inner parts.

Since the TV is made up of glass, it is important to see that care is taken while handling it. Also it should not be exposed to shocks or vibrations, as this could affect the performance of the TV. The outer surface of an LCD TV is made up of soft material and so it is important not to use any sharp articles near it. Since it s made of glass, strong vibrations or shocks should not be given to it, as the glass can be broken if something like that happens. Also it should not be bent or dropped from a high altitude.

Before handling it, care should be taken to first ground it by ESD protection devices and also use soft things like gloves, as there are many sensitive parts inside and it would also prevent damaging of the screen. Care should also be taken while cleaning the LCD, as it should be cleaned preferably with Hexane or IPA, as otherwise the polarizer can be affected.

Also a very important thing to be noticed is that these TVs should never be re-assembled without the proper guidance of a qualified operator, as the original performance and charm of the TV can be destroyed, if handled by an amateur. Also the screen should be turned off when not in use or a screen saver that changes frequently should be used. If the same picture is left for long, then the brightness of the TV can get reduced and can also result in sticking of the images on the screen.

An LCD TV is an owners’ pride and it is an ecstasy to watch favourite TV shows and movies in an LCD. With just little care while handling the TV, it can give many advantages and lots of fun to its owner.

Pressure transducers

Only the front face of a pressure transducer is exposed to the sound field. The diaphragm responds equally to all sound pressure fluctuations hitting the surface, doesn’t matter form which direction the sound. Pressure transducers have no directional characteristic, and are Omni directional.

Pressure gradient transducers

These microphones have a figure-8 pickup pattern along the longitudinal axis. They respond to the momentary sound pressure difference between two points A and B, which are a slight distance apart in the sound field.

Pick up Patterns

Omni directional

An Omni directional microphone, reveres to Omni because it hears from all direction. Provide the fullest sound from a distance. Omni is good to capture ambience and the room sound.

Pressure transducer

Bidirectional

Bidirectional microphones only hearse from the front and the back and nothing from the sides.

Cardioid

Hears most of its sounds from the front and only a little from the back.

Transducer type

Magnetic Induction Transducer

Dynamic microphones work on the basis on magnetism. As the coil, that is mounted to the diagram moves in and out in relation to the SPL and cuts through the magnetic field. A current is induced in the coil, and that is a voltage representation of the sound.

Variable Capacitance Transducer

There are two plates placed close to each other, there is a potential difference on the plates. As the SPL hits the diaphragm the plates start to bind in relation to the sound. As the plates bend it causes electrons to jump, and you will get the voltage representation of the sound

Multi Pick up pattern

1. A microphone with multiple pickup patterns typically uses voltage difference between two condenser cardiod capsules. The different voltages on the plate causes different pick up patterns. Here are the different voltages on the different plates.

Omni = + +

Fig 8 = + -

Cardiod = + -

Cardiod = + +

2. A microphone with ports on their side provides an alternate way to put the sound from the back and the sound from the front out of phase. And change between Omni and cardiod.

Omni = Ports are blocked

Cardiod = Ports open

Fig 8 = Ports open, have more ports

As may be expected, it may take a few more years for this technology to be available for home use. On the other hand, flat screen TV’s, satellite programming, and many other technologies can still help you create a home theater that can easily rival anything you would find at a move house or other entertainment establishment.

If you have children, or you enjoy a wide range of entertainment oriented programming, it may be of some help if you have a home theater installed.

So you are looking to enter the exciting world of home theater with the addition of a home HD projector. One of the terms you are sure to read about or hear from your salesman is projector lumens or projector ANSI lumens.

First things first, what does projector lumens refer to? Simply put, lumens is the measure of brightness of the image at the screen.

ANSI (American National Standards Institute) is the “official” standard for measuring light output that each home HD projector can project. You will see the term projector ANSI lumens describing the capabilities of each projector.

Keep in mind that published projector lumens ratings can be a bit misleading. For example, a projector may be rated for 1300 lumens, but may only be capable of 350 lumens in the highest quality mode. The image that is produced at the maximum lumens rating is often times nearly unwatchable for high definition viewing. Other things affecting the brightness of the image is the projected size of the image, the distance of the projector from the screen and the gain on the projector screen.

Keeping the limitations of published lumen ratings in mind, the following are some general recommendations for high definition projectors:

For a screen size of 92″ you would want a projector with a minimum rating of 900 lumens for areas with complete light control, 1000 lumens for areas with some ambient light and 2000 lumens for areas of bright light such as daytime watching in rooms with windows.
For a screen size of 120″ you would want a minimum rating of 1200 lumens for complete light control, 1300 for areas with some ambient light, and 2500 for rooms with a lot of ambient light.

If you are looking for a projector for business presentations, the ANSI lumens rate is vitally important because the detail of the image is not as critical, but the ability to see the image with ambient light is critical.

While it is important for a high definition projector to be able to produce a bright image, particularly in areas of moderate to high ambient light, a home hd projector’s contrast ratio is arguably more important then it’s projector lumens rating. The contrast ratio measures the ratio between white and black. A higher contrast ratio will indicate deeper black levels which will greatly enhance the viewing experience with more shadow detail and more visual “pop” on the screen.

A digital projector review is designed to provide potential buyers with the necessary information to make informed decisions when looking to purchase a new digital projector. With an ever increasing number of manufacturers and vendors jumping on the digital technologies bandwagon the projector market has grown from three or four brands to over twenty and this number is set to grow with the onset of HDTV.

While digital projector competition is good for consumers and can only serve to push prices down, the economic win is a double-edged sword. The rapid expansion in both the range of projector products and prices has created a buyers nightmare, even for the savviest shopper. Confusion reigns supreme, LCD or DLP, Lumens 500 or 5000, Aspect Ratio (4:3) or (16:9), Native or Natural Resolution or Maximum Resolution. The list of confusing, but supremely important features goes on and on and there are plenty of unscrupulous salesmen out there eager to pounce on your confusion. But don’t worry there is help out there in the form of digital projector reviews.

There are three types of digital projector review, those written by the manufacturers, those written by technology magazines and those written by consumers. While the glossy marketing and flashy descriptions found in manufacturer brochures form a persuasive argument, the content is often marketing hype outlining only the projectors strengths. A manufacturer produced digital projector review is a great document to keep for comparing key features and costs, but I would not recommend you use it as your only decision-making tool.

Similarly, many reviews found in gloss magazines fall in to the same category as those of the manufacturers. A digital projector review found in a paid subscription is in many cases, a purchased advertisement placed by the manufacturer, or product promoter. In saying this I must point out that there are also several high quality subscription and online magazines that provide excellent independent product reviews. The problem for the consumer is trying to ascertain which digital projector review is a paid advertisement and which review is a true non-bias piece of writing.

For the most reliable reviews, consumers win hands down and here’s why. The people are actually using the product. Unlike the manufacturer or the salesman the user has no hesitation in voicing concerns over product quality, performance, durability and ease of use. More importantly, many of these consumer digital projector reviews are found in forum sites and bogs, Often other people have added comments about their experiences with the product, both positive and negative, giving you an honest and complete overview of all the product..

If your considering purchasing a digital projector, I recommend the following strategy.

1. Use the manufacturer developed gloss brochures to do your product range and price homework

2. Make a shortlist of digital projectors that meet both your quality and price range requirements

3. Check out some blog reviews about the products you are considering.

4. Make an informed digital projector purchase.

Happy viewing.

Why shouldn’t you buy a 60-inch plasma TV? Because there’s a much better, affordable solution. How would you like to be able to look at an 8 FOOT screen with quality comparable to 16mm film projection? What if I said you could get it for under $1200? Well, you can with a projection TV.

Projection TV

If you’re going low-budget, one well-reviewed option is the Mitsubishi HC3000U High Definition 720p DLP Home Theater Projector. PC World, the computer magazine, honored the HC3000U with a 2006 PC World Innovations Award after comparing it to hundreds of other products. Compared to other projectors, the midtones are much brighter, which results in richer blacks and a more vivid image overall. It’s even a cinch to install. As of this writing, it’s run you about 950 bucks.

Mounting Hardware

If you’re planning on mounting the projector in the ceiling, you could go with the Atdec TH-WH-PJ-FM Telehook Universal Projector Flush Mount. The mount allows the projector to be rotated a full 360 degrees, and has a quick release for easy installation. That’ll run you about 50 bucks.

Projection Screen

You’ll want a screen to go along with your home theater projector. You could project it on a bare white wall, but you won’t get the best possible performance out of your projector. The budget option is to get a manual screen, as opposed to an electronically operated one. One highly-rated manual screen is the Draper Screen Luma 106″ Diameter. That’s about 130 bucks.

Audio

If you’re hooking your equipment up to your stereo, you’ll already have excellent sound. That’s the budget solution anyway.

Summary

Did I keep my promise to get you a killer home theater system for 1200 bucks? Let’s see — $950 for the projection TV, $50 for the mounting hardware, and $130 for the screen. Happy viewing!
