Most LCD TVs either use a long string of LEDs around the edge of the panel or a thin sheet of LEDs across the back to light up their screens, meaning that large areas of the screen are lit by just a few LEDs -- and generally that's meant that LCDs have struggled to display bright whites alongside dark blacks.
