Abstract

A liquid crystal display including a liquid crystal display panel and a backlight module disposed under the liquid crystal display panel is provided. The backlight module includes first light sources, second light sources and a light source driver. The first light sources are arranged in a first area under the liquid crystal display panel, and the second light sources are arranged in a second area under the liquid crystal display panel. The light source driver is electrically connected to the first light sources and the second light sources. The light source driver drives the first light sources to turn on and turn off in a scan frequency and drives the second light sources to keep light. A driving method for liquid crystal display includes driving the light sources under a dynamic image to turn on and turn off in a scan frequency and driving the light sources under a static image to keep light while the liquid crystal display panel displays simultaneously the dynamic image and the static image.
