Abstract
The disclosure provides a liquid crystal display driving circuit and a liquid crystal display device. The liquid crystal display driving circuit includes a content adaptive brightness control circuit and a Gamma voltage adjustment circuit, when the content adaptive brightness control circuit is turned on, the brightness of the backlight module is switched from first backlight brightness to second backlight brightness under the control of the content adaptive brightness control circuit, when the brightness of the backlight module is the first backlight brightness, the Gamma voltage adjustment circuit outputs a first Gamma voltage for adjusting grayscale brightness of the liquid crystal display to be first grayscale brightness, when the brightness of the backlight module is the second backlight brightness, the Gamma voltage adjustment circuit outputs a second Gamma voltage for adjusting the grayscale brightness of the liquid crystal display to be second grayscale brightness.
