There are mainly two kinds of projectors, video projectors and transparency projectors. Under the video projectors, there are four kinds. These are the LCD projector, CRT projector, DLP projector and LCOS projector. As for the transparency projector, it has the movie projector, slide projector, and overhead projector.
An LCD projector is also known as a liquid crystal display. It uses a metal halide lamp in order to send light through the LCD panels so as to display images. It is the modern slide projector and overhead projector of today.
CRT projectors are popularly known as video projectors. It utilizes high-brightness picture tubes or CRT so as to create an image. The created image is then enlarged and focused with the use of a lens. This lens is placed behind the face of the CRT.
A DLP or digital light processing device uses a Digital Micromirror Device (DMD). It is a small memory chip which adjusts the electromagnetic mirrors for every pixel in the image. It is also good to use even in rooms that are lit.
LCOS stands for liquid crystal on silicon. It is known as a micro-projection technology device which is used for televisions. Like DLP, it makes use of reflective technology but has liquid crystals instead.
Under the transparency projector, the movie projector uses films on a reel to form moving pictures. A slide projector also enlarges photographic slides on the screen. The overhead projector also enlarges images of pictorial or written material on a transparency that is placed underneath the projector.

Video Projector Buying Guide
In the past, video projectors were limited to high-end home theater installations that were very expensive, but today these same types of high definition projectors are available for less than $2,000.
Whether you plan on using a video projector for professional or personal use, a projector can provide you with many benefits. Depending on what you will be using the projector for, there are certain things you should look for before making a purchasing decision.
Below you will find a set of questions that our product specialists ask our customers before recommending a projector for them to buy.
How much light is in the room you plan on using the projector in? Generally, the more light that enters the room the more Lumens you will need a projector to have. The more Lumens a projector has, the brighter the picture will display, making it easier to see when in a room with a lot of light. Note that a projector with less than 1000 Lumens might require you to block out almost all of the external light in order to be able to see the picture clearly.
What aspect ratio do you want the projector to display in? The two main types of aspect ratios are either 4:3 (standard) or 16:9 (widescreen and HDTVs). Most people now are choosing projectors in the 16:9 format for their home theaters, while a few prefer the 4:3 format as many movies created before 1953 are in that format.
Do you plan on taking the projector around with you? If you want a projector that is easy to take around, from room to room or office to office, consider the size and weight of the unit. The lighter and smaller the projector, the more portable it will be.
Do you care about the contrast of colors in the picture displayed? If you want a good contrast in your colors, such as blacker blacks and whiter whites, then take a look at the contrast ratio of a given projector. The range of contrast ratios is anywhere between 500:1 and 5000:1 and more. The higher the contrast ratio is, the higher the amount of available colors. Therefore the higher the contrast ratio is the more life like images the projector can produce.
How do you plan on connecting to the projector? Make sure that the projector in question has all of the inputs you plan on using available. These include S-Video, Composite, Component, HDMI, as well as many others.
What type of accessories do you want with the projector? Projectors can come with many accessories, including the necessary cables to make a connection such as an s-video cable, HDMI cable, or something of the like. Make sure the projector has the necessary cables when purchasing a projector. Other accessories can include remotes, lasers, lens cap, etc.
Lumens: The unit of measure for the light output of a projector.
S-Video (Separated Video): An analog video signal that carries the video data as two separate signals.
Composite: A single video connector that combines all the color and brightness signals into one cable using a single RCA male connector. Often color-coded yellow, it is the most common type of analog video connection between older VCRs and TVs.
Component: Video signal in which the luminance and sync information are recorded separately from the color information. Component is superior to composite.
Definitions:
HDMI (High Definition Multimedia Interface): HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio all on a single cable.
4:3 Standard Aspect Ratio: The shape of standard (non-widescreen) TVs, which simply means the picture "frame" is 4 units wide for every 3 units tall.
16:9 Widescreen Aspect Ratio: The shape of widescreen TV's, which simply means the picture "frame" is 16 units wide for every 9 units tall. This ratio is used for high definition televisions.

Should Businesses Buy a Projector or an LCD Display?
With the price of large (>32”) LCD displays decreasing rapidly and new functionalities being added to LCD displays, does it still make sense for businesses to buy a projector vs. an LCD display?
Some of the variables to consider when evaluating this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business organization perspective. Read other articles and make your informed judgement.
Product Life: LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the display on for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be replaced in most LCD displays. A projector bulb typically has a life of 2,000 hours.
Price Considerations: A basic projector can be found for INR 25,000. However, if the projector is going to be used for video conferencing or board room presentation, a high resolution, good contrast ratio and saturated colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to factor in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to compare a projector vs. an LCD (see chart below). With 46” LCD TV or display costing around Rs 135,000 – Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD display
Figure: Total Cost of Ownership Comparison for Projector vs. LCD Display
Basic Device capital cost for projector is INR 70,000 and that of an LCD display is INR 150,000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10,000, Consumable cost of the projector is 20,000 x 3 = INR 60,000, Consumable life of a projector is 2,000hrs and that of an LCD display is 60,000hrs and the Cost of Ownership of a projector is Rs.140, 000/- and Rs.150, 000/- for an LCD display.
Assume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the customer to buy 3 lamps in addition to 1 supplied with machine.
What is clear from the above figure is that a Full High Definition 46” LCD Display is, at best, only marginally costlier than a XGA Projector of ~2500AL. Additional costs of low screen installation costs and lower device loss costs are purely additional.
Picture Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can see the different colours at the borders of an image, aptly described as the rainbow effect. The rainbow effect takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow effect, however the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow effect issues and the quality of the picture is good at close range.
Rather, projectors cannot compare with the picture quality for an LCD display. The vividness of the colours, the contrast ratio, the colour saturation and image sharpness are much better for an LCD display than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the lights or close the curtains unless the business has purchased an even more costly higher lumen projector. Not true with LCD displays, as the brightness and colour quality are much better.
Viewing angles used to be an issue with LCD displays but this issue is no longer true. Most LCD displays can be viewed from up to 176 degrees.
Dead or Stuck Pixels: Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels and stuck pixels result in white spots in the projected image. However, the manufacturers of both technologies have worked hard to minimize such issues and in most cases they provide warranty against such issues.
Screen Size: A common thought is that screen size is not an issue for most projectors as the thinking is that the projector image can be made larger by moving the projector away from the screen. This is not true as the image quality deteriorates as the image becomes larger. With projectors, most buyers opt for maximum optimized projector image sizes from 76-inches to 120-inches and the actual working normal projection image used is much smaller. Today, if businesses need a large LCD display in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.
Portability: Projectors are easy to carry and move around. For a business this could be a value-add or a drawback. LCD displays are durable and can be moved however they are not as light as projectors.
Power Consumption: Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to compare the two technologies on this performance parameter.
Connectivity: Most LCD displays have more number and different types of ports than projectors. As a result more types of devices can be connected to an LCD display than a projector.
Other Value-Add Features: New features are appearing in LCD displays that could be quite valuable for businesses. For example, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data written on the display can easily get captured electronically in a text document.

Video Projectors - Advice On Choosing The Right Model For Home Or Business
As video projectors become more affordable then more people are using them both at work and at home. You might be thinking that projectors are all alike and the more you spend the better it will be. Well this is not strictly true. The more expensive projectors will be of a higher standard, but you might not experience any benefit if you do not choose the correct model. This is why we have written this article to try and guide you and help you choose the model most suited to you.
Before any purchase it is important to have a think about what you will be using it for and in what kind of environment. The business user will have very different requirements to someone wanting to set up a home cinema. Companies are now marketing hybrid projectors that claim to be able to be used for both home cinema and business. These two environments are very different though and will need projectors designed specifically to be able to handle these two very different uses. As you read the rest of the article you will begin to understand what you need to look out for when purchasing your video projector.
LCD or DLP
Both are excellent formats and which you choose will depend on your use. The business user will be more suited to an LCD projector due to the increased brightness. The home user on the other hand would be better to opt for a DLP projector as these will give a more cinematic experience.
Brightness
Think about the level of ambient light in the room where you will be using your projector. In the home cinema you will hopefully have control of the level of light so this will not be an issue. If you are using a room at home that has ambient light then you will need to opt for a brighter projector. In the business arena you are likely to be presenting in very bright rooms with standard office lighting and windows. A good projector for business use will need to have a high brightness level.
Brightness is measured in ANSI lumens. For home cinema you should be looking at projectors that have around 700 ANSI lumens brightness and for business projectors you will need between 1000 and 1500.
Color
The color, gray-scale performance, and video playback, are only really important to the home user as they will give more natural and detailed videos.
Contrast
There is no point spending money on a high contrast video projector for business use or use in a room at home that has significant ambient light as your eyes will not notice the benefit. If you have a dedicated cinema room at home then it will be worth looking at projectors with contrast ratios of 400:1 or higher. If you are looking for a projector for business use then there is no point by one with a ratio of higher than 400:1
Portability
This will probably only be an issue for a business user. If you travel around a lot and take your projector with you then the more compact and light the better. It is possible to buy extremely light projectors.
The home user may not be concerned too much with size and weight, but it is worth considering how you will set your projector up at home. Will it be fixed to the ceiling or on a stand? If you have it on the ceiling you should look for a projector which comes with a remote control as this will make adjusting settings a lot easier.
We hope that this look at the differences with video projectors will help you make your decision.

How To Choose A Projector
By Jakob Culver
Good presentations make the foundation of the successful business deals. So while making presentations make sure that you have an easy access to a good projector which suits your requirement as this is going to at as a catalyst for a business deal to happen! The picking of projectors is mainly dependent on the type of work or the kind of business that you have. As for an advertising firm presentations are very frequent so they make doubly sure that they procure a good projector!
The other factor that determines the selection of a projector is the dimension of the room or the conference hall where the presentation is scheduled. As the clarity and readability of the data projected varies from the projector which is designed to function in small room as compared to large room , so presentations for larger areas and for a great number of people should be made through more sophisticated projectors.
Portability of the projector is the another issue, if you usually travel from one place to another for their business presentations then make sure that you invest in a good quality portable projector that is easily transported and provides an easy set up. It is mandatory that it can be set up instantly as who would be carrying a throng of technical people when doing mobile presentations. A projector that easily connects with a personal or portable computer will be ideal to make your presentations simple but sophisticated.
Norms suggest that a portable projector with a minimum brightness capacity of at least 800 lumens is fine to handle the presentations. In contrast to this larger projectors must have a brightness capacity of at least two thousand lumens to make the presentation clear even to those who are seated at the back of the room. A projector must have at least a minimum of 1500 lumens to be able to project effectively in a room where plenty of light comes in as when there are no blinds or curtains
Once you have decided on the type of the projector that you will be using, then make sure that you use projectors in a dark room but if it cannot be avoided, always position the projector at an area where there is less light. It is also important to take note of the resolution of your projector as this signifies the amount of pixels it can display. . Projectors can be easily installed but it is best to consult technical people for setting up the projector especially if they will be mounted to the ceiling. Make sure your projector's efficiency will last long by using alcohol or a special cleaning solution for the projector lens.
So go ahead and make a appropriate selection from a wide variety of projectors that are available in the market and just to tell you that vendor will be one happy person to give a trial presentation, so make sure that you don’t miss on that as it will throw more light on the projector features.
