Display panel with embedded fingerprint recognition and touch function, driving method thereof and display device

A touch display panel, comprising:

• a common electrode layer, comprising a plurality of touch electrodes arranged in an array;
• a plurality of scanning lines, extending in a row direction of the touch electrodes;
• a plurality of detection lines, extending in a column direction of the touch electrodes;
• a plurality of first thin film transistors, wherein the first thin film transistors are in one-to-one correspondence to the touch electrodes, a drain electrode of each of the first thin film transistors is coupled with a corresponding touch electrode, a gate electrode of the each first thin film transistor is coupled with one of the scanning lines, and a source electrode of the each first thin film transistor is coupled with one of the detection lines;
• a first gate driving circuit coupled with one end of each of the scanning lines;
• second thin film transistors which are in one-to-one correspondence to the scanning lines;
• a display enable signal line;
• and
• a common voltage signal line;
• wherein a drain electrode of each of the second thin film transistors is coupled with one of the scanning lines, a gate electrode of the each second thin film transistor is coupled with the display enable signal line, and a source electrode of the each second thin film transistor is coupled with the common voltage signal line;
• wherein the first gate driving circuit is arranged on a same side of each of the scanning lines,
• the each second thin film transistor is arranged on an other side of the each scanning line;
• and
• an extending direction of the display enable signal line and an extending direction of the common voltage signal line are the same as an extending direction of each of the detection lines.
