Display device, method for driving a display device, and display driving circuit

A method for driving a display device, wherein the display device comprises:

• n rows of sub-pixels, n being a positive integer and n>2;
• each frame of image is configured with a corresponding display period and a corresponding darkness insertion driving period, and the display period comprises a display driving period and a blank period which are not overlapped with each other, the darkness insertion driving period comprises a first darkness insertion sub-period and a second darkness insertion sub-period, and for a same frame of image, the first darkness insertion sub-period is after a starting time of the display driving period and before the blank period, the second darkness insertion sub-period is after a starting time of the blank period;
• the method comprises:
• performing driving for the first frame of image, which comprises:
• sequentially performing normal display driving on the n rows of sub-pixels in a corresponding display driving period, performing darkness insertion driving on a rows, from the 1st row to the ath row, of sub-pixels in a corresponding first darkness insertion sub-period, and performing darkness insertion driving on (n−a) rows, from the (a+1)th row to the nth row, of sub-pixels in a corresponding second darkness insertion sub-period, where a is a positive integer and a<n;
• performing driving for a second frame of image, which comprises:
• performing normal display driving on the n rows of sub-pixels in a corresponding display driving period, performing darkness insertion driving on b rows, from the 1st row to the bth row, of sub-pixels in a corresponding first darkness insertion sub-period, and performing darkness insertion driving on (n−b) rows, from the (b+1)th row to the nth row, of sub-pixels in a corresponding second darkness insertion sub-period, where b is a positive integer, b<n and b≠a.
