Abstract
A touch display panel is disclosed. The touch display panel includes a substrate, a touch layer, and a first demultiplexing circuit. The first demultiplexing circuit includes demultiplexing units. The demultiplexing units include first transistors and second transistors. By disposing a gate electrode of the first transistors connected to a gate electrode of the second transistors in one of the demultiplexing units, time-sharing drive is realized in the first transistor and the second transistor through a signal, which can reduce a number of signals required by the demultiplexing circuits.
