Home Theater Projectors

With the advent of home theaters the craze of watching movies in a real theater has faded out to a considerable extent. More and more people are looking forward to watch the much awaited and most favorite movies in the cozy comfort of their homes. Therefore the new buzzword is Home Theater. Home Theater consists of a projector and a screen.

Home Theater Projector
The projector is the device that helps in displaying the image as a response to an image output signal from the image supply apparatus like the computer or the DVD player. Initially projectors were used for conferences and meetings, presentations, exhibitions and demonstrations and those projectors were known as data projectors since they only displayed statistical graphs, surveys and documents but now they are being used for the purpose of entertainment.

Home theater projectors refer to the Front Projectors, which are ceiling mounted or placed on a shelf or in the most common cases placed on a table. It can also be used in a rear screen arrangement but then space poses a problem for rear screen arrangement. Most of the home theaters are widescreen-producing images. They are designed to operate in a dark room to facilitate clear picture, if that is not possible you a more powerful projector should be chosen. Modern Home Theater projectors use technology like The LCD, DLP and LCOS. Each technology is being tried and each has it’s own set of advantages and disadvantages. Most of the projectors are networked essentially with a receiver, a Home theater PC, speakers, screen, DVD player, cable box and a satellite box. Built-in or All-in-one home theaters are also available in the market. The rear projector consists of an image generator, which generates a projection image, a case that accommodates the generator, a reflection mirror and a transmissive screen. The reflection mirror reflects the projected image.

Home theater projectors generate a big picture that is not appropriate for small rooms. The other disadvantage is that the light has to be minimum since the pictures are projected with the help of a light source and any other light coming from any other source interferes with it. To have the best results the home theater has to be dedicated with a separate room, which is dark and is big enough for all the paraphernalia of the projector and the home theater.The cost of a projector can cost more than the television or the screen to be precise. The projectors can cost around $3000.

Home Theater Projection Screen
In a home theater the images are displayed on the projector screen projected from the projector. These screens provide excellent picture quality and are one of the trendiest home accessories in modern times. It is one of the most important parts of a home theater system besides the projector. The screen can either be a front projection screen or a rear projection screen. Flat screens are the most appropriate ones for front projection screen that are retractable and you have the option of rolling it up. Most of the screens have the velvet covering so that the extra light can be absorbed. The type of projectors that are being used, the seating arrangement and the distance between the screen and the projector should determine the screen type. There are Plasma and LCD screens as well, which have great picture quality. They are very convenient but also very expensive. Plasma Screens are susceptible to Burn-ins and consumers do complain that displays on a plasma screen are big enough but then the image if left on the screen for long time actually causes damage. A flat Plasma screen can be beneficial since it is compact and real pleasure to the eyes.
