1. A touch circuit, comprising:
a touch IC including a data signal port and a clock signal port;
a first pull-up sub-circuit electrically connected to a first signal input terminal and the data signal port of the touch IC, wherein the first pull-up sub-circuit is configured to transmit a signal from the first signal input terminal to the data signal port; and
a second pull-up sub-circuit electrically connected to the first signal input terminal and the clock signal port, wherein the second pull-up sub-circuit is configured to transmit the signal from the first signal input terminal to the clock signal port;
a first switching sub-circuit electrically connected to the data signal port, the first signal input terminal and a data signal input terminal, wherein the first switching sub-circuit is configured to transmit a signal from the data signal input terminal to the data signal port under control of the signal from the first signal input terminal; and
a second switching sub-circuit electrically connected to the clock signal port, the first signal input terminal and a clock signal input terminal, wherein the second switching sub-circuit is configured to transmit a signal from the clock signal input terminal to the clock signal port under control of the signal from the first signal input terminal;
wherein the signal from the data signal input terminal is transmitted to the first switching sub-circuit earlier than the signal from the first signal input terminal, and the signal from the clock signal input terminal is transmitted to the second switching sub-circuit earlier than the signal from the first signal input terminal.
