Many of today's models of projectors are compact in size. Such devices can be used as home multimedia equipment, the main thing is to choose the right option … In this article, we will take a closer look at such devices and learn all about the features of their choice.

Features and purpose

Portable projectors made in mini format are produced by many well-known brands . Today the range of these devices is huge - you can choose the best option for any purpose and conditions of use. Many devices are perfect for home use. It is very convenient to use portable equipment as a home appliance . She not only does not take up much space, but is also easily transferred from one room to another, if the need arises.

Just because a projector is portable does not mean it is less functional or less ergonomic . Many of today's small devices boast rich functionality. Portable products can have built-in wireless modules, all the necessary and up-to-date connectors, speakers and other useful components.

The purpose of any projector is quite obvious. It is worth considering in what situations it is advisable to buy a portable device.

1. If you do not use wireless multimedia compact equipment too often, and you rarely want to admire the picture on the wall, then it is better to purchase a mini-model of the projector. Standard models require a separate secure mount and dedicated space. In an inactive state, these components will only interfere with household members.
2. Portable devices are a great solution if you are looking for the perfect presentation technique. The latter can be carried out not only at home, but also in any other locations. You can even take high-quality devices without wires with you to nature.

A modern portable cinema projector can replace the average TV . There are many multifunctional compact devices with good technical parameters. Let's consider what types of such devices are subdivided according to their characteristics.

Image format

Modern models of projectors are very popular, which differ " Native" aspect ratio 16: 9 . Devices with such parameters are produced by many brands. A technique that can reproduce a picture of this format will be an excellent solution for lovers of high-quality widescreen pictures. True, many of the portable projectors that produce images in this format are expensive.

There are also compact projectors with an aspect ratio of 4: 3 . Such devices are considered a little outdated, especially against the background of devices with a 16: 9 picture. However, they are optimal for those users who want to watch a classic film in good quality and are generally used to a 4: 3 picture. As a rule, such pictures are projected on the whole screen.

Image output technology

There are several special technologies for displaying an image on the screen .… Let's consider the most popular and frequently used ones.

DLP

Most modern projectors use this technology. At the heart of such devices there are micromirror matrices … All tiny mirrors reflect the image from the light source, and a complete picture is formed from the dots.

LCD

This popular technology is based on a liquid crystal matrix , which includes 3 primary colors - RGB. Each crystal cell is equal to 1 pixel.

LCoS

This is a kind of combination of the technologies described above. Based on liquid crystal matrix, but at the same time its transmission does not occur - it is reflected. The stream of light is bounced off the mirror surface and redirected directly to the canvas with the image.

Laser

Devices with such technologies work as follows: the light rays that exit the apparatus combine to form a coherent image . The peculiarity of such structures is that there is no lens here . There is no scattering of impulses, there is no need for focusing.

The projector optics with this technology only adjust the tilt angle.

Optics type

Different models of portable projectors have a different optical system, which consists of a lamp and a lens. Let's consider what lamps can be installed in the projector compact equipment.

• Gas discharge … In special cases, an electric discharge is used, hence a fairly powerful stream of light and images of high brightness are obtained. Such lamps are small in size.
• Metal halide . Such lamps are among the best in terms of price-quality ratio. They can generate a good stream of light. Their power indicators can only decrease towards the end of the resource. In many instances, special filters are installed.
• Projection … These are the types of lamps that have the best technical characteristics. Thanks to them, the picture is saturated, contrasting and clear enough. High-quality paints are stored for a long time.
• Xenon . Such lamps are often found in professional-type equipment. It is rather difficult to find these optical objects in portable devices. Xenon lamps can produce large, clear and rich images.
• LED . LED lamps are also often found in modern projectors of various modifications. Such elements consume a minimum of electrical energy, which makes the equipment more economical to use.

If the indicated values are lower, then the picture quality will not be flawlessly high either.
• Specifications . In addition to these parameters, it is worth paying attention to other characteristics of the technique. Pay attention to how long the projector can work in standalone mode, whether it has wireless networks, what connectors are present in its design, what formats it can read.
