How a home theater projector works

There are various types of projectors on the market that have their own strengths and weaknesses, which must be considered when choosing. If we consider the display technology in detail, it looks like this. There is a lamp inside the device, which provides powerful illumination during the show. When the light stream passes through the optical system, it is divided into three colors, green, red and blue. The light then passes through a modulator, which can be liquid crystal or micromirror matrix. It has a pixel structure, allowing you to build a high-quality image.
What is a home theater projector, how to choose and connectThe control unit is designed to work with the pixel matrix. Image focusing is performed by using a lens that brings together streams of different colors and finally forms an image.

What types of projectors are there

There are mainly three types of projectors on sale: LCD, DLP and LED. Each of them will be discussed in more detail below.

LCD projectors

These devices are the most affordable. In them, the image is formed using a liquid crystal matrix. The popularity of such projectors is largely due to the affordable price. This technology was further developed in the form of 3LCD, the main difference of which is the use of three liquid crystal matrices instead of one. These models provide higher quality but are more expensive.

DLP projectors

This type is similar in price to LCD projectors, but provides higher image quality. Such a device, using a mirror matrix, smooths out image imperfections and makes it more vivid and impressive. However, these projectors have a disadvantage, which is commonly referred to as the iris effect. It implies that rings of several colors can form around objects moving on the screen.

LED projectors

The devices under consideration can be used with different types of lamps, which increases the choice. They ensure high quality of work and at the same time are energy efficient.

How to choose a home theater projector

The design of various types of such equipment can differ significantly from each other. One of the most important elements of such equipment is the lamp used. The quality of lighting largely determines the level of viewing comfort. High pressure discharge lamps are often used as the light source. Their main disadvantage is their relatively rapid wear. Replacement is usually required after 2000-4000 hours of operation. In some cases, their resource can reach 8000 hours. In practice, the replacement has to be done after 3-4 years, and in some cases more often. In order to extend the life of such lamps, manufacturers began to use UHP technology. These lamps use a discharge for illumination that occurs between tungsten electrodes. These lamps are compact yet provide an even and intense glow.At the same time, high quality color reproduction is ensured.
What is a home theater projector, how to choose and connectUHP lamp [/ caption] These lighting fixtures gradually decrease in intensity as they wear out. The service life often does not exceed 2000 hours. Changes were made to their device that helped to partially compensate for the problems mentioned. HCX lamps also have a relatively short lifespan that is comparable to that of other projection lamps. Metal halide lamps create light due to the discharge of an electric arc that is created in a gas under high pressure. They differ from UHP lamps in the composition of the gas, in which additives are made that improve the quality of spectral radiation, contribute to its uniformity. As a disadvantage, a gradual loss of quality is noted as the service life expires, which can reach up to 50%.
What is a home theater projector, how to choose and connectP-VIP lamps are considered to be of the highest quality compared to other varieties. Their service life is 6000-8000 operating hours. An important feature of such lamps is constant brightness throughout the entire life of the lighting fixture. Xenon lamps use compressed Xenon to fill the bulb. Such lighting devices provide high power and intense luminous flux. High power and quality of work led to the fact that they are used for projectors in cinemas.
What is a home theater projector, how to choose and connectThe use of gas-discharge lamps, due to their inherent disadvantages, is gradually becoming a thing of the past. Instead, LED lighting is gradually becoming more popular. The use of light-emitting diodes has made it possible to extend the life of the device, increasing it to 20 thousand hours. Such lighting devices allow for a high-quality display without special requirements for the surface on which the display is performed. The disadvantage of such lamps is the insufficiently strong luminous flux compared to other types of lamps.

Therefore, the most attractive option can be considered hybrid lighting, which combines the advantages of laser and LED.

What characteristics to pay attention to

When choosing, you must carefully consider the various characteristics of the projector. Following is noteworthy:

  1. The brightness of the light source should be sufficient for comfortable viewing of films. It is recommended to choose models that provide an illumination of 1000-2000 lm.
  2. It is necessary to take into account the format of the resulting image and the aspect ratio of its sides . For a home projector, use 16:10 or 16: 9 is fine.
  3. It is worth paying attention to the uniformity of the illumination of the entire screen . There should be no darker or too light areas here. In the technical specifications, a parameter is used that is equal to the ratio of brightness in the center of the screen and at its edges, but it is not always indicated.What is a home theater projector, how to choose and connect
  4. Consider the presence of noise during the operation of the projector . Typically, the source is the ventilation system used in the appliance. You need to be sure that the sound will not interfere with the comfortable viewing of the film.
  5. You need to check the level of contrast . It has a significant impact on viewing quality in shaded rooms. If you plan to view in good lighting, then you need to take into account the brightness to a greater extent. It is believed that for comfortable viewing, this characteristic should be in the range from 1000: 1 to 2000: 1.

Since the projector displays files from external sources, it is important to consider what connectors it has for a cable or for a flash drive. In the latter case, the video file can be displayed without connecting to a computer.
