Direct Full Array 8X³, Direct Full Array 16X³ what it is, what is different from Full Array Backlight
Direct Full Array 8X, Direct Full Array 16X
In 2019, Samsung in the specifications of some TV models the type of backlight indicates the parameter Direct Full Array 8X³, Direct Full Array 16X³.
What this parameter means, Direct Full Array, it is clear that the backlight in the TV is located throughout the screen area and the LEDs are at the back, but what is 8X³, 16X³
This designation is no different from the previously used Samsung Full Array Backlight. This is just a marketing ploy from Samsung. Since in 2019 there are no special changes in TVs, then to promote sales, companies practice the same technologies called different names.
Direct Full Array 8X³
The parameter Direct Full Array 8X, laid the following characteristics. The number of zones of illumination that can be controlled, this value is shown not by a number, but as a formula.
- 8X³ you can imagine
- 8×1³ = 8 backlight zones
- 8×2³ = 64 backlight zones
- 8×3³ = 216 backlight zones
- 8×4³ = 512 backlight zones
As a rule, the number of backlight zones is a multiple of 8, for control and tied to the number of bits (8). If you follow the logic of the formula, Samsung TVs do not contain more than 512 blackout areas. Since 8×5³ = 1000, and there should be 1024 zones for control. 512 zones is enough to control the blackout on the TV.
Direct Full Array 16X³
16X³ you can imagine
- 16×1³ = 16 backlight zones
- 16×2³ = 128 backlight zones
- 16×3³ = 432 backlight zones
- 16×4³ = 1024 backlight zones
