Preferably, the pitch between two adjacent second vacuum holes 13 is 5 mm. In some embodiments, the supporting region 111 has a plurality of adsorption regions, each adsorption region has a plurality of second vacuum holes 13 arranged in an array, at this time, the pitch between two second vacuum holes 13 closest to each other in two adjacent adsorption regions is L2, and satisfies L2 mm 13mm, L2 may be 10mm, 11mm, 11.5mm, 12mm, 12.5mm, and 13mm, so as to avoid that the adsorption force at the middle position of the flexible display panel is weak due to a large interval between two adjacent adsorption regions.
