A touch display substrate, including: a substrate including a display region and a non-display region; a plurality of common electrode blocks spaced apart from each other; a plurality of wirings; a vertical shift circuit including a plurality of cascaded vertical shift circuit units, and each of the plurality of vertical shift circuit units is connected with wirings corresponding to a column of common electrode blocks, and is configured to sequentially output touch driving signals to the column of common electrode blocks; and a controlling IC configured to output a touch driving signal to the vertical shift circuit; wherein, the plurality of common electrode blocks are divided into n groups of common electrode blocks by columns, and the controlling IC is configured to apply scan pulse signals with different frequencies to the groups of common electrode blocks in different touch scanning time periods.

Touch display substrate

A drive circuit of a display panel, a display panel, a display device and a method of driving a display device are provided. The circuit comprises: j select circuits and j data line signal output circuits, j is an integer greater than or equal to 2. Each data line is connected with a select circuit, different data lines are connected with different select circuits, each select circuit is connected with the j data line signal output circuits, each select circuit can control the data line connected therewith to be connected with one of these j data line signal output circuits and to control the data line connected therewith to be disconnected from the other ones of these j data line signal output circuits; so pixels at different locations can be scanned by powering the data lines connected with the pixels using the different data line signal output circuits.
