In the description of TVs or monitors you can see the type of DLED screen. It is clear that this is a matrix of the screen with LED backlighting, and in fact now practically no other matrices are produced. Manufacturers have modernized production and transferred the backlight to LEDs instead of lamps. This is more economical, and also allows you to make, if necessary, a darkening (turning off) of some area of the screen.
DLED -this is an abbreviated name for the type of backlight Direct LED, LG came up with its own name, calling this technology FALD (full-array local dimming).
The name DLED is needed only because of marketing. For example, they will write that in 2018 DLED technology was used on the TV. And the buyer does not know that this technology has been used in televisions since 2012.
