Claim Text:
1. A touch display circuit comprising a touch unit and a display unit which are connected with each other; a first scan line, a second scan line, a third scan line, a signal control line, a data line, a first level terminal and a second level terminal, which are connected with the display unit; and the second scan line, the third scan line and a signal collecting line, which are connected with the touch unit; the display unit comprises a driving module and a light-emitting module; the driving module is connected with the first scan line, the second scan line, the signal control line, the data line, the first level terminal and the touch unit; the light-emitting module is connected with the driving module, the third scan line and the second level terminal; wherein the driving module provides a first voltage level to the touch unit under controls of the first scan line, the second scan line, the signal control line and the data line; the touch unit outputs a first amplified signal acquired by amplifying the first voltage level to the signal collecting line, or the touch unit outputs a second amplified signal to the signal collecting line as touched; the driving module provides a light-emitting signal to the light-emitting module through the first level terminal and the second level terminal under the controls of the first scan line, the second scan line, the signal control line and the data line; and the third scan line controls the light-emitting signal so as to drive the light-emitting module to emit light.
