PROBLEM TO BE SOLVED: To provide a touch sensor circuit and a touch display device the charging efficiency and the sensing efficiency of which can be improved.SOLUTION: The touch sensor circuit includes a charging capacitor, a first current supplying unit, a second current supplying unit, and a switch unit. The charging capacitor is serially connected between a detecting terminal and a reference voltage. The first current supplying unit is coupled to the detecting terminal, and receives a first bias voltage signal, and generates a first charging current at the detecting terminal on the basis of the first bias voltage signal. The second current supplying unit is coupled to the detecting terminal, and receives a second bias voltage signal, and generates a second charging current at the detecting terminal on the basis of the second bias voltage signal. The second terminal and a third terminal of the switch respectively supply the first and the second bias voltage signal. |
