A driving circuit and a pin output order arranging method are disclosed. The driving circuit includes (M*N) pins and an arranging module. A first pin˜an N-th pin of the (M*N) pins, a (N+1)-th pin˜an 2N-th pin of the (M*N) pins, . . . , a [(M−1)*N+1]-th pin˜a (M*N)-th pin of the (M*N) pins are arranged along a first direction in a specific distance spaced to form a first row of pins˜an M-th row of pins. The first row of pins˜the M-th row of pins are staggered along a second direction in a staggering way or an aligning way. M and N are integers larger than 1. The arranging module correspondingly arranges the pin output order of the (M*N) pins according to different application modes of the driving circuit.
