Abstract
The present disclosure discloses an in-cell touch screen panel, a driving method thereof and a display device. A plurality of sub-pixels are grouped into sub-pixel groups, each of which includes at least two sub-pixels. Cathode layers of different sub-pixel groups are independent of one another. The cathode layers are reused as self-capacitance electrodes. A driving chip determines a touch position by detecting a change in capacitance of the cathode layers, thereby achieving touch control functionality. The driving chip outputs, in a fourth phase, signals to the cathode layers and to the signal terminals of each sub-pixel circuit, each of the signals is a superposition of the signal output in a third phase with a touch scanning signal such that each sub-pixel circuit operates in the fourth phase in the same state as in the third phase.
