Abstract
A touch circuit includes: a touch IC; a first pull-up sub-circuit; a second pull-up sub-circuit; a first switching sub-circuit configured to transmit a signal from a data signal input terminal to a data signal port under control of a signal from a first signal input terminal; and a second switching sub-circuit configured to transmit a signal from a clock signal input terminal to a clock signal port under control of the signal from the first signal input terminal. 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.
