Driving method and driving apparatus for display apparatus

A driving apparatus for a display apparatus, for driving a 3D display apparatus, wherein the 3D display apparatus comprises a pixel array comprising a first view pixel cell and a second view pixel cell;

• each of the first view pixel cell and the second view pixel cell is formed by N sub-pixels with different colors arranged cyclically in one column, where N is an integer larger than or equal to 3;
• the first view pixel cell and the second view pixel cell are arranged alternately in a column direction;
• each row of the pixel array comprises sub-pixels with an identical color;
• and the driving apparatus comprises:
• a receiving unit configured to receive an image signal and extract a first view and a second view from the image signal;
• a dividing unit configured to divide the first view and the second view respectively into multiple virtual pixels, and to obtain a color component corresponding to a color of each sub-pixel in the multiple virtual pixels;
• a arranging unit configured to arranging a sampling region in the pixel array of the display apparatus for each sub-pixel of each view;
• a processing unit configured to determine a gray scale signal of the sub-pixel corresponding to the sampling region according to the color component corresponding to the color of each sub-pixel in each virtual pixel covered by the sampling region, wherein the virtual pixel covered by the sampling region and the sub-pixel corresponding to the sampling region belong to a same view;
• and
• a displaying unit configured to display the image signal according to the gray scale signal of the sub-pixel.
