Abstract
There are provided a touch circuit, a touch panel and a display apparatus. The touch circuit comprises: an input module (1), a reset module (2), a pull-up module (3), a pull-down module (4), a pull-down control module (5) and a touch signal output module (6), wherein the input module is configured to provide a signal of the first reference signal terminal to the first node; the reset module is configured to provide a signal of the second reference signal terminal to the first node; the pull-up module is configured to provide a signal of the first clock signal terminal to the control signal output terminal; the pull-down module is configured to provide a signal of the third reference signal terminal to the control signal output terminal; the pull-down control module is configured to ensure a potential of only one node of the first node and the second node is a first potential at a same moment; the touch signal output module is configured to output a high frequency signal or a common voltage signal to a touch signal output terminal under the control of the control signal output terminal. The touch circuit, the touch panel and the display apparatus have a simple structure, and relativ…
