Screen Backlight Technology:

In the description of the technical characteristics of TV screens, you can find application of various types of backlighting (Dimming). A little bit about backlighting in LCD TVs to see the image you need to place behind the screen a light source.

FALD - (full-array local dimming),

2018 LG decided to build an advertising company to promote TVs in the markets, with the abbreviation FALD. Although the TVs with this backlighting are produced from 2012 and it was called Direct LED. The advantages of this backlighting technology are the ability to apply the backlight off by sections, which makes it possible to get a deeper black color on the screen. As a rule, the backlight LEDs are assembled into groups (zones) and turn off the illumination by sections, such zones can be several dozen.

LCD- 

this abbreviation accepted TV is used as the backlight of the matrix, it is the first technology that was used in flat TVs, at this stage, the old lights, TVs release this technology is reduced every year.

LED - 

This technology has replaced a simple LCD technology in this case, the LEDs are used as light sources.

Direct LED - 

LED lights positioned in the entire area of the screen, the advantages of the possibility of using local dimming, a disadvantage is a large TV thickness. This technology is used in television sets of various series.

EDGE LED - 

LED backlight screen is placed on the side, the advantages of the thickness of the TV is smaller deficiencies are not possible to use a full local dimming, occupancy diodes does not allow certain sections of the screen darken.

LED  Plus -

 the same EDGE LED only realized the possibility of local dimming but not small portions and large, for example, or the left or right area of the screen.

NANO Full LED - 

the same Direct LED but as they say in the scattering layer is added to the microparticles that allows you to make softer lighting. But basically it's just a marketing ploy company.
