Therefore, the number of the first driving units 31 in the first non-display area B1 is 640. The number of rows of pixel rows 2 in the third display area A3 x the total number of rows of pixel rows 2 in the display panel/(the number of rows of pixel rows 2 in the first display area a 1+ the number of rows of pixel rows 2 in the third display area A3), i.e., the total number of rows of pixel rows 2 in the display panel, i.e., the total number of rows of pixel rows 2 in the first display area a1
