At first, according to pixel multiplexing multiple n, determine the red, green, blue three-primary color LED chip of each pixel on the display screen and the mapping relations of image source, for any one led chip, its primary colours show that data show data corresponding to these primary colours of n adjacent pixel of image source, this primary colours data addition of the n that this is an adjacent pixel obtains the demonstration data of this led chip divided by n; Wherein each pixel on the display screen is made of transversely adjacent three-primary color LED chip or constitutes by vertically going up adjacent three-primary color LED chip; The image source pixel is carried out after three-primary color LED chip that pre-service obtains each pixel shows data, these are shown that data deliver to display screen by scan drive circuit and show.

7. the method for realization pixel multiplexing according to claim 6 is characterized in that described pixel multiplexing multiple n=3, on the display screen arbitrary led chip show data be D (x, y):

D(x,y)＝[d(x-1,y-1)+d(x,y-1)+d(x,y)]/3

Or D (x, y)=[d (x-1, y-1)+d (x-1, y)+d (x, y)]/3

Or D (x, y)=[d (x-1, y)+d (x, y-1)+d (x, y)]/3

Or D (x, y)=[d (x-1, y-1)+d (x-1, y)+d (x, y-1)]/3

Wherein D (x, y) x in, y represent capable sequence number and the row sequence number of pixel under this led chip respectively; (x is that the capable y row of image source x pixel is corresponding to the primary colours demonstration data of this led chip y) to d.

8. the method for realization pixel multiplexing according to claim 6 is characterized in that described pixel multiplexing multiple n=6, on the display screen arbitrary led chip show data be D (x, y):

D(x,y)＝[d(x-1,y-1)+d(x-1,y)+d(x-1,y+1)+d(x,y-1)+d(x,y)+d(x+1,y+1)]/6

Or

D(x,y)＝[d(x-1,y-1)+d(x-1,y)+d(x,y-1)+d(x,y)+d(x+1,y-1)+d(x+1,y)]/6

Wherein D (x, y) x in, y represent capable sequence number and the row sequence number of pixel under this led chip respectively; (x is that the capable y row of image source x pixel is corresponding to the primary colours demonstration data of this led chip y) to d.
