Of course, in other embodiments, the same arrangement of sub-pixels may also be used in the first boundary region 140 and the second boundary region 142 , which is not limited in this application.

Further, please continue to refer to FIG. 1 , at least one interface area 14 further includes a third interface area 144 connecting the first interface area 140 and the second interface area 142, and the sub-pixels of the main display area 10 in the third interface area 144 are alternating The first sub-pixels 160 and the second sub-pixels 162 are arranged, and the sub-pixels of the sub-display area 12 in the third boundary area 144 are third sub-pixels 164 arranged in sequence.
