dynamic contrast

Adjusting the LED backlight in an LCD TV or monitor on the fly to create a higher contrast ratio. When a dark image is displayed, the LEDs are dimmed or turned off behind the pixels. When light areas are displayed, the pixels are artificially brightened by turning up the LEDs. See LED TV and contrast ratio.
