Abstract:
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.
