Abstract
A liquid crystal display device includes a liquid crystal display panel, a light source configured to provide the liquid crystal display panel with a light, a vertical blank detector circuit configured to calculate a counting value of a vertical blank period of a frame by counting a synchronization signal, a luminance correction value calculator circuit configured to calculate a luminance correction value by comparing the counting value of the vertical blank period with a plurality of reference counting values, and a light source driver configured to generate a light source driving signal and provide the light source driving signal to the light source. The light source driving signal has a normal level corresponding to a normal luminance value in an active period of the frame and has a correction level corresponding to the luminance correction value in the vertical blank period of the frame.
