Portable TVs: choice, features and reviews

Historically, people are closely connected with new technologies: telephones, tablets, laptops, etc. Portable TV sets also play an important role in the lives of every second consumer. They allow you to receive new information, as well as just a good rest after a day's work. And many men will be hurt if they need to go with their family to a picnic, and at this time a long-awaited match is broadcast. It is in this situation that mini digital TVs come to the rescue.

Half a century ago, manufacturers had an idea to create such a device. However, some details, while being too bulky, did not allow to reduce the size of the instruments. This was done only in the 21st century, when the distribution got a liquid crystal screen.

Description of the liquid crystal display

Liquid crystal screen (LCD) is a technology that consists in the fact that liquid crystals are located between two glass plates. The latter are parallel to each other. When the electric current acts on the crystals, they change their transparency, due to which the picture appears. In this case, the more they are in space, the clearer and brighter the image will be. The main indicator of the quality of the demonstration is the resolution.

In the plates there is a set of cells that are directly in the matrix itself. They have light filters. Thanks to the last person sees a color image. The main shades of three are green, red and blue. This is what distinguishes portable TVs from conventional ones. In old devices, you can often see flicker, while LCD screens do not have such anomalies.

Types of Portable LCD TVs

At the moment, the market is filled with portable TVs. Most often there are devices with a diagonal of 5 to 9 inches. Options with large indicators are almost not bought by consumers (they are too high price), so their production was reduced.

In order to choose between the screen 4: 3 and 16: 9, you need to determine what you need the device to buy. Portable TVs with an antenna, used for watching TV channels, have a lower resolution. And to watch DVD-ROMs have to look at an expensive option. In principle, some models have the function of stretching the image, but then there is a risk of skipping the running line from below or any other text that is at the edges.

Price policy does not tolerate too much change for several years, so you can say for sure that depending on the diagonal and functions, an ordinary portable device will cost in the amount of 4 thousand to 17 thousand rubles.

Characteristics of televisions and their complete sets

Portable technology has a weight of not more than 300 g (while manufacturers are constantly seeking to reduce it), and sizes from 3 to 10 inches. The quality of the image depends on how the signal is transmitted: via the built-in antenna or the connected tuner. The latter is capable of receiving both digital and analog television. In the complete set, as a rule, there is a small panel, ear-phones, a support for fastening. Devices are considered universal due to the fact that the manufacturer can supply, together with the TV adapter for the cigarette lighter, batteries and a network adapter.

More recent models have USB-outlets and a slot for reading a memory card. This expands the functionality of the TV, allowing you to view materials from both a flash card, and from a phone or tablet. In some cases, there is also a function for viewing photos. Due to this they are more successful than analogues without such an option. There are TVs with wireless network support.
