Now on sale mostly liquid crystal televisions prevail, more and more displacing plasma counterparts from the market.

What features should be present in modern TV

Consider the fundamental difference between them, what are the pros and cons, the functions of modern TVs. What you should pay attention to when choosing, and what new technologies are used in the most modern blue screens.

Plasma TV. Features of the "plasma" is that the screen consists of matrices filled with a special inert gas. Under the influence of voltage, this substance goes into a plasma state and glows.

The main advantages of this type of TV are:

• due to fast image updating, excellent clarity of moving objects;
• large viewing angles;
• deep black color and high contrast.

Their main disadvantages include:

• this technology does not allow producing models with small diagonals;
• high power consumption;
• Relatively more weight than LCD screens

• lower brightness of the picture, which is especially felt in lighted rooms.

Liquid crystal. What features should a modern TV have? LCD TVs by the type of screen backlight are divided into LCD (liquid crystal display), where the glow is provided due to fluorescent or fluorescent lamps and LED (Light-emitting diode), where diode lamps are used.

Advantages:

• low power consumption;
• slim body;
• wide selection of diagonals;
• increased service life;
• Significant image brightness
• light weight.

Disadvantages:

• image distortion at large viewing angles;
• lower contrast and saturation of black;
• low-quality video quality is worse than on "plasma".

IMPORTANT LED TVs are superior to LCD in a number of ways - this is lower power consumption, higher contrast, natural colors and sharpness, lack of mercury in LED matrix. The disadvantage is the higher price.

What features should be in a modern TV? When buying a TV most often pay attention to the screen brightness, diagonal, sound quality and the possibility of improving it. Compatibility with gadgets and ease of operation through the remote control and ease of use of the menu. The presence of a built-in media player, the number of USB, VGA and HDMI connectors. For advanced users, it is important to have a wireless Internet or cable connection and data exchange technologies.

Data exchange

In premium-class televisions, data exchange technologies between devices are increasingly being used, we highlight the main ones:

1. DLNA - integrates Hi-Tech devices into a local network.
2. Miracast - allows you to transfer information via Wi-Fi, without joining a LAN.
3. WiDi - provides the transfer of video broadcast on the gadget via Wi-Fi.
4. NFC - quick and convenient pairing of mobile devices or a computer with a TV receiver.

Smart tv

Smart TV technology provides an Internet connection for accessing applications and broadcasting various content. In this case, it is more convenient to use a smartphone as a control, if the TV has such an opportunity.

3D support

3D technologies are active and passive. Active provide high image quality without additional software settings, which affects the cost of the receiver in the direction of appreciation. Passive are convenient to use and easier to manufacture, so models with them are cheaper.

Advanced 3D TVs have the following features:

1. PiP technology - picture in picture.
2. Translation of a flat image into a three-dimensional one.
3. Controlling the depth of a three-dimensional image.
