Abstract: A liquid crystal display device and a driving method thereof are disclosed. The method for driving the liquid crystal display device comprises the following steps: converting three primary color gray-scale data of a frame image to be displayed into multiple color gray-scale data; and driving different sub pixels according to the overdrive gray-scale values that are obtained through inquiring the overdrive table based on the multiple color gray-scale data of the frame image to be displayed according to a certain time sequence in two color fields. According to the method, the color shift phenomena of the traditional liquid crystal display device can be alleviated effectively.

Abstract: A backlight module includes a substrate having an opening on top, a first reflective plate disposed on a bottom surface of the substrate, light guide plates disposed on the first reflective plate with intervals in between, backlight source components, and a plurality of optical films disposed on the opening of the substrate. The backlight source components comprise heat sink shelves, and point light sources that are fixed on the heat sink shelves and inserted in the interval between two neighboring light guide plates. The present invention effectively reduces the width and thickness of the backlight module, and is instrumental for a narrow-frame and ultra-thin design, effectively reduce production cost. Meanwhile, the arrangement ensures good backlight uniformity, and is instrumental in reducing the distance needed for light mixing. Additionally, the defect of dark band appearing around the backlight module of traditional backlight modules can be effectively eliminated.
