Abstract
A touch circuit includes a first pull-up sub-circuit, a first switching sub-circuit, a second pull-up sub-circuit, a second switching sub-circuit and a touch IC. The touch IC includes a data signal port and a clock signal port. The first pull-up sub-circuit is electrically connected to a first signal input terminal and the data signal port. The first switching sub-circuit is electrically connected to the data signal port, the first signal input terminal and a data signal input terminal. The second pull-up sub-circuit is electrically connected to the first signal input terminal and the clock signal port. The second switching sub-circuit is electrically connected to the clock signal port, the first signal input terminal and a clock signal input terminal.
