Abstract
A touch display panel includes a first sensing matrix and a second sensing matrix. The first sensing matrix includes a plurality of grid units and a first switch unit. The grid units are arranged in matrix, wherein each grid unit includes at least one first electrode. The first switch unit includes a plurality of switches, and the switches are disposed between adjacent grid units. Wherein, the control end of the switches is configured to receive a first controlling signal, and one end of each of the switches is configured to output a sensing signal. The second sensing matrix includes at least one second electrode, and is configured to receive a common signal. The second sensing matrix includes a plurality of opening units, and each opening unit overlaps with the open area of each pixel circuit in a vertical projection direction of the first substrate.
