Abstract: A method, a circuit and a display device for driving an organic light emitting diode, wherein a driving transistor (DTFT) for driving a display element is turned off by jumping one or more of a reference voltage input (Vref), a reset voltage input (Vinit) and a data signal input (Vdata) before beginning to output an EL high level (ELVDD) of a pixel compensation circuit and after beginning to output an EL low level (ELVSS), to overcome the splash screen phenomenon during power-up and direct current-direct current driving failure.

Abstract: 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, and cathode layers of different sub-pixel groups are independent of one another. The cathode layers are reused as self-capacitance electrodes, and a driving chip determines a touch position by detecting a change in capacitance of the cathode layer, thereby achieving touch control functionality. The driving chip outputs, in a fourth phase, signals to respective cathode layers and 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.
