Abstract
A multipath selection circuit includes a first data line, a second data line, a third data line, a control line, a timing line, a switch circuit, and a drive circuit. The drive circuit includes a first switching transistor and a second switching transistor. The switch circuit is configured to receive a control signal, timing signal, first data signal, second data signal and third data signal, and operate in a first operating mode or a second operating mode according to the control signal and the timing signal. In the first operating mode, the switch circuit is configured to transmit the second data signal to the first switching transistor and the second switching transistor in a time division manner; and in the second operating mode, the switch circuit is configured to transmit the first data signal to the first switching transistor and the third data signal to the second switching transistor.
