Techniques

An LED-backlit TV

[edit]Edge-LEDs

This method of back-lighting allows LED-backlit displays to be extremely thin. The light is diffused uniformly across the screen by a special panel.

[edit]Full-array LEDs

Many brands use LED backlighting technology, which can offer benefits over CCFL LCDs of reduced energy consumption, better contrast and brightness, greater color range, more rapid response to changes in scene and more accurate image rendering.[3]

[edit]Dynamic “Local Dimming” LEDs

This method of backlighting allows local dimming of specific areas of darkness on the screen. This can show truer blacks, whites and PRs[4] at much higher dynamic contrast ratios by dimming or brightening the backlight locally, at the cost of less detail in small, bright objects on a dark background, such as star fields or shadow detail.[5]
