Claim 18:
19. The flexible display apparatus according to claim 17, wherein:
the second rolling axle is rolled with N rounds of supporting plates; a length Lk of a supporting plate at a k-th round is less than a length Lk+1 of a supporting plate at a k+1-th round; and a distance between two adjacent locking parts fitted in the supporting plate located at the k-th round is equal to the length Lk of the supporting plate, wherein 0<k≤N;
the length Lk of the supporting plate at the k-th round is calculated as follows:, L
