A touch sensing circuit, a method thereof, a panel and a touch sensing display apparatus. The touch sensing circuit comprises: a first gate line, a second gate line, a data line, a signal transmission line and a common electrode, wherein the first gate line, the second gate line and the data line define multiple pixel units, a first switch tube, a second switch tube and a third switch tube are formed inside the pixel units, and the signal transmission line is connected to a signal processor; the third switch tube is connected between the first switch tube and the second switch tube in series; a first node is formed at a connection position of the first switch tube and the third switch tube, a second node is formed at a connection position of the second tube and the third switch tube, a first capacitor that is invariable is formed between the first node and the common electrode, and a second capacitor that is variable is formed between the second node and the common electrode; and the signal transmission line is connected to the second switch tube, and the data line is connected to the first switch tube. Sensitivity of touch sensing is improved. |
