1. A method of driving a display device, comprising:
- dividing sub-pixels of a display panel into a plurality of array blocks, and selecting at least one of the sub-pixels in each of the array blocks as a luminous pixel;
receiving a to-be-displayed image, acquiring a pixel signal of a pixel of the display panel, obtaining the pixel signal from a look-up table, and obtaining first driving signals of the sub-pixels;
calculating a first brightness signal of driving the luminous pixel in the array block according to the first driving signals of the sub-pixels in each of the array blocks; and
using the first brightness signal to drive the luminous pixel, and using the pixel signal to drive other ones of the sub-pixels,wherein the step of calculating the first brightness signal of driving the luminous pixel in the array block according to the first driving signals of the sub-pixels in the same array blocks is performed according to;
L=1*L5+0.8*(L2+L4+L6+L8)+0.4*(L1+L3+L7+L9);
where L1, L3, L7 and L9 represent the first driving signals of the four sub-pixels at diagonal positions;
L2, L4, L6 and L8 represent the first driving signals of another four sub-pixels neighboring the sub-pixel located at a center position of the array block; and
L5 represents the first driving signal of the luminous pixel, and L represents the first brightness signal which needs to be calculated.
