1. A flexible circuit board comprising:
a main body sub-circuit board comprising a first substrate, and a first bridge connection end, a second bridge connection end, a first wiring portion and a second wiring portion on the first substrate, in which the first wiring portion and the second wiring portion are separated from each other and electrically connected to the first bridge connection end and the second bridge connection end, respectively;
a bridge sub-circuit board comprising a second substrate, and a third bridge connection end, a fourth bridge connection end and a third wiring portion for a first functional wiring on the second substrate, in which the third bridge connection end and the fourth bridge connection end are electrically connected by the third wiring portion, and
a first control circuit combination structure, in which the first control circuit combination structure is disposed on the main body sub-circuit board and electrically connected to the first wiring portion, or the first control circuit combination structure is disposed on the bridge sub-circuit board and electrically connected to the third wiring portion, the first control circuit combination structure being configured to provide a first electrical signal to the first functional wiring or receive a first electrical signal from the first functional wiring,
the bridge sub-circuit board being configured to be installed on the main body sub-circuit board by electrically connecting the third bridge connection end and the fourth bridge connection end to the first bridge connection end and the second bridge connection end, respectively, so that the first wiring portion, the third wiring portion and the second wiring portion are sequentially electrically connected to obtain the first functional wiring;
an outline shape of the first substrate being different from that of the second substrate; and
the main body sub-circuit board further comprising a second functional wiring, the second functional wiring being electrically connected to the first control circuit combination structure on the main body sub-circuit board, the first control circuit combination structure being further configured to provide a second electrical signal to the second functional wiring or receive a second electrical signal from the second functional wiring.
