TV receiver has undergone so many metamorphoses and transformations that lamp ones were only memories. The last time — the appearance of a liquid crystal display (LCD). Manufacturers offer a variety of technology improvements, introduced the original know-how, thus expanding the range and breadth of concepts. How not to get lost?

LCD is a device with a particular screen. It's 2 circuit boards between which the space is filled with liquid crystals under pressure. The lattice of these elements, color filters, a protective coating and be sure the light source is to illuminate this multilayered structure.

Due to the special design LCD TV got a lot of advantages:

  • ergonomics;
  • versatility (for home, office, for easy viewing of programs or of use in a multitasking mode home theater);
  • energy efficiency.

The vastness of the concepts
Don't just buy a LCD TV, because the described design involves the use of different technologies LCD and its backlight. We will not delve into the complexity of the structure of crystals and their connections (IPS/VA type of matrix), let's talk about the light sources.
Modern LCD TV offers led backlighting. The brightness of the local areas is changing point that provides a more rich and detailed color reproduction and contrast. LED elements compact that allows you to create ultra-thin, lightweight large-screen TVs. Items glow all the energy transformerait in the light, not heat, so the equipment on their basis of energy-efficient and reliable.

One of the latest developments of OLED devices. Don't confuse LCD TV with backlit LED's and OLED panel. The last screen made entirely of LEDs organic type and contains liquid crystals. the image forming LEDs, no filters, LCD matrix.

When choosing a TV receiver take into consideration the viewing angle of the screen, type of display, illumination, power built-in video card and processor. These hardware components directly affects the quality of image and speed of response when playing dynamic scenes.
