According to the method and the device, the shadow area is scanned line by line, and the ranges of the left side and the right side of the shadow area are calculated to determine the coordinate range of the partition area corresponding to the Kth LED lamp bead in the first quadrant.
Specifically, assume that the screen ratio of the display terminal is 16:9, the size of the video picture can be set to 16px9p. The number of the LED lamp beads at the top of the display screen in the first quadrant is m. The input pixels correspond to rows X and columns Y, and as the K area completely falls in the second quadrant region, the range of the column pixels, namely the range of Y coordinates, is half of the wide side of the video picture size, namely, 0-straw Y-straw 4.5p
Specifically, as shown in fig. 6, a partition area corresponding to the kth LED lamp bead is a shadow area, and end points of the shadow area are three points B1C1O respectively; the A1G1 line segment is half of the long side of the display terminal, i.e., A1G1= L1/2= 169/2; if the total number of the lamp beads on the long side or the wide side of the display terminal is m, the length occupied by each LED lamp bead is 16p/m, and the length occupied by the Kth LED lamp bead is L2=16pk/m, that is, B1G1= L7= L2-16p/2= 169k/m-16 p/2; the length of the (k-1) th LED lamp bead is L3=16 (k-1)/m, that is, G1C1= L6= L3-16p/2=16 (k-1)/m-16 p/2; the connecting line OF the point D1, the point E1 and the point F1 is parallel to the point G1A1, and the variation range in the Y direction is 0 to 4.5p, and assuming that the length OF G1F1 is Y, OF1= L4=9p/2-Y, and OG1= L5=9p/2.

The number of the LED lamp beads at the top of the display screen in the second quadrant area is m. The input pixels correspond to rows X and columns Y, and since the K area completely falls in the second quadrant region, the range of the column pixels, namely the range of Y coordinates, is half of the wide side of the size of a video picture, namely 0-Y-4.5p
Specifically, as shown in fig. 7, the partition area corresponding to the kth LED lamp bead is a shadow area, and end points of the shadow area are three BCO points respectively; the AG line segment is half of the long side of the display terminal, i.e., AG = L1=16p/2; if the total number of the lamp beads on the long side or the wide side of the display terminal is m, the length occupied by each LED lamp bead is 16p/m, and the length occupied by the Kth LED lamp bead is 16pk/m, namely AC = L2=16pk/m; the length occupied by the (k-1) th LED lamp bead is 16 (k-1)/m, namely AB = L3=16 (k-1)/m; connecting lines OF the points D, E and F are parallel to the GA, the variation range in the Y direction is 0-4.5 p, and assuming that the GF length is Y, OF = L4=9p/2-Y, and OG = L5=9p/2; GC = L6= L1-L2; BG = L7= L1-L3.
Specifically, in the triangular OBG, the following relationship can be obtained according to the trigonometric function:
DF/BG＝OF/OG；
EF/CG＝OF/OG；
