Abstract
A touch driving circuit includes first touch signal terminals, second touch signal terminals and analog front-end circuits. A number of the first touch signal terminals is greater than a number of the second touch signal terminals, and a number of the analog front-end circuits is equal to the number of the second touch signal terminals. Each analog front-end circuit in at least one analog front-end circuit is connected to at least two first touch signal terminals, and the analog front-end circuit connected to the at least two first touch signal terminals is configured to receive first touch detection signals from the at least two first touch signal terminals in a time-sharing mode. An analog front-end circuit is connected to a second touch signal terminal, and the analog front-end circuit is configured to receive a second touch detection signal from the second touch signal terminal.
