Liquid crystal display apparatus and method for displaying pictures

A liquid crystal display apparatus, comprising:

• P kinds of sub-pixels with different colors, wherein P is an integer more than 1;
• a liquid crystal display driving device configured to transmit data signals to the respective sub-pixels in order to drive them to display pictures, the liquid crystal display driving device being configured to display each picture at a display period of N frames, wherein N is an integer greater than or equal to 2, and wherein the liquid crystal display driving device is further configured to display the sub-pixels with any one of Q colors in normal state in the N frames, wherein Q is an integer, 0<Q<P, and wherein the liquid crystal display driving device is further configured to, in the display period of each picture, display the sub-pixels with the color other than the Q colors in dark state in at least one frames and in normal state in the frames other than the at least one frames, wherein the number of the frames in which the sub-pixels with the color other than the Q colors are displayed in normal state is at least one, and wherein the sub-pixels in dark state have lower luminance than those in normal state,
• wherein the P kinds of sub-pixels with different colors are red sub-pixels, green sub-pixels and blue sub-pixels, and the sub-pixels with the Q colors comprise green sub-pixels, and wherein all of the red sub-pixels are displayed in normal state in greater than N/2 frames in each display period.
