摘要： A touch driving detection circuit includes a plurality of region driving detection circuits. Each of the plurality of region driving detection circuits includes a control module, a strobe output module, a detection module, a first trigger signal line and a second trigger signal line. The first trigger signal line is configured to input a first trigger signal to the control module to control the strobe output units to output touch scanning signals simultaneously. The detection module is configured to detect whether a touch is present in the touch region and when a touch is present, the detection module triggers the second trigger signal line in the region driving detection circuit to input a primary trigger signal, so that the control module controls the strobe output units to output the touch scanning signals sequentially, thereby determining a location of a touched point in the touch region.

摘要： A touch display panel, a driving method and a touch display device are provided. Touch and display are driven synchronously in the touch display panel. That is, touch detection is implemented while the display is performed and there is no need to perform the display and the touch in different stages, thereby avoiding limiting an improvement on a report rate, and ensuring a high report rate of the touch display device.
