FALD vs LED vs Direct LED vs Edge LED vs LED Plus vs NANO vs Full LED screen backlight technology explained
In the description of the technical characteristics of TV screens, you can find application of various types of backlighting (Dimming), which they mean we will consider in this article. A little bit about backlighting in LCD TVs to see the image you need to place behind the screen a light source.
Direct led vs Edge led backlight
Direct led vs Edge led - Of course, the Direct LED backlight is much more efficient, as it allows you to control the backlight on the TV. Significantly improved image quality. Televisions in the upper price range use only Direct Led backlight. The matrixes of screens are made with support for controlling the backlight LEDs by zones. Produced models of screens in which the backlight can be divided into more than 200 zones.
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. A banal marketing move to present your products in a more favorable perspective. 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 backlight
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 backlight
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 backlight
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 backlight
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.
So there are only two types of highlighting Direct and EDGE. All other names are improvements to the backlight. Namely, the implementation of the ability to control the backlight focusing on the displayed image. Also, let's not forget marketing, if even on TV nothing has changed, then inventing a new name for the screen backlight, an increase in sales of televisions is achieved.
When choosing a TV, you need to focus on the type of backlight. Also, TVs with Direct backlight and the ability to control the brightness of the backlight, depending on the image on the screen, will show a better image.
