In addition, the pixel arrangement structure has decisive influence on the performances of the LED display screen, such as brightness, response speed, color quality, service life and the like.
The prior Chinese patent No. CN115084186A discloses a pixel arrangement structure and a virtual pixel structure based on the pixel arrangement structure. The pixel arrangement structure disclosed in the patent CN115084186a includes a plurality of physical pixel units arranged in a matrix form, each of the physical pixel units includes four sub-pixels (i.e., sub-pixels, or referred to as light emitting components), which are a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel, respectively; in the a direction (i.e., column direction, longitudinal direction), the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel are sequentially arranged; in the B direction (i.e., the row direction, the lateral direction), the first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel are sequentially arranged in a staggered manner.

Therefore, the source pixel points of the driving signals of the pixel units which are arranged at the 1 st row along the column direction and the 2 nd column along the row direction are the pixel points which are arranged at the 1 st row and the 1 st column, the 2 nd row and the 1 st column, the 3 rd row and the 1 st column, the 1 st row and the 2 nd column, the 2 nd row and the 2 nd column and the 3 rd row and the 2 nd column in the video source.

Therefore, the source pixel points of the driving signals of the pixel units which are arranged in the 2 nd row along the column direction and the 1 st column along the row direction are the pixel points which are positioned in the 3 rd row and the 1 st column, the 4 th row and the 1 st column, the 5 th row and the 1 st column and the 6 th row and the 1 st column in the video source.
