摘要： A liquid crystal display (LCD) device includes a display control circuit to receive data of each frame of an external image signal and a liquid crystal panel. When the data of an n+1 frame currently received is the same as that of an n frame previously received, the display control circuit outputs first gray scale voltages corresponding to the data of the n+1 frame to drive the liquid crystal panel. When the data of the n+1 frame is different from that of the n frame, the display control circuit generates data of at least one inserted frame between the data of the n and the n+1 frames, and outputs second gray scale voltages respectively corresponding to the data of the at least one inserted frame and the n+1 frame to drive the liquid crystal panel to display first an image of the least one inserted frame and then that of the n+1 frame. An absolute value of a second gray scale voltage exceeds that of a first gray scale voltage for a same gray scale.
