Display driving method and device, and display device

A display driving device for a display device, the display device comprising:

• a plurality of sub-pixels arranged in an array;
• a plurality of data lines, each column of the sub-pixels corresponding to and connecting to one data line, and adjacent data lines having one column of the sub-pixels disposed therebetween;
• and
• a plurality of grayscale pixel groups, each of the grayscale pixel groups comprising sub-pixels 10 of a 2N×3M matrix, where N and M are positive integers,
• the display driving device comprising:
• a data obtaining module, configured to obtain a first to-be-processed chroma dataset and a second to-be-processed chroma dataset of a preset scene in a to-be-displayed image with respect to a preset color;
• a data processing module, configured to obtain Gaussian probability of the preset scene in the to-be-displayed image with respect to the preset color according to the first to-be-processed chroma dataset and the second to-be-processed chroma dataset;
• and
• a comparison driving module, configured to compare the Gaussian probability with a predetermined threshold, when the Gaussian probability is greater than or equal to the predetermined threshold, set polarities of the sub-pixels in adjacent columns of each grayscale pixel group to be opposite to each other, set the polarities of the sub-pixels adjacent to the grayscale pixel group in a row direction to be symmetrical to the polarities of the sub-pixels of the grayscale pixel group, and then display the to-be-displayed image;
• when the Gaussian probability is less than the predetermined threshold, set the polarities of the sub-pixels in adjacent columns to be opposite to each other, and then display the to-be-displayed image.
