Samsung LED LCD TV adopts side-mounted white light backlight, which not only makes the TV body extremely thin, but also scans the input signal in advance because of the "LUXIA" engine specially controlling LEDs, and then determines the brightness of LED backlight in the current picture. When it is necessary to display a completely black scene, the LED will be turned off in an instant, and the LCD screen without backlight will turn black completely. When it is necessary to display pictures with different blackness, the LED backlight will change brightness at any time with the change of the picture, showing dark scenes with different blackness. Therefore, users can get more saturated colors and clear gradation in the process of enjoying movies or games, especially in the transition of light and dark colors. It can be said that through the realization of "absolute blackness", Samsung has raised the picture quality of LED TV to a new height. In addition, Samsung's unique black crystal panel gives full play to the advantages of LED backlight. Samsung's black crystal panel reduces the interference of reflected light through a patented process similar to mirror treatment. Even when it is turned off, the screen looks darker and purer. In the final picture quality, the black bit ability is greatly improved, and the color transition of the picture is more vivid and natural, which can make the picture with a lot of detailed information fully explored.
