Abstract
A touch sensing circuit and its control method is disclosed herein. The touch sensing circuit includes a plurality of detecting units. The detecting units are arranged in an array, in which each detecting unit includes a sensing pad, a first switch and a second switch. The first switch is configured to selectively conduct the sensing pad and one of a plurality of signal lines. The second switch is configured to selectively conduct two adjacent sensing pads. When the first switches in a first row in the array are on, the sensing pads in the first row are configured to output detecting signals to the signal lines according to a driving signal, and the second switches in a second row adjacent to the first row are on to conduct the sensing pads in the second row to receive and transmit the driving signal together.
