Abstract: The present invention provides a touch display panel and a display device. The touch display panel includes a substrate, which is provided thereon with a common electrode layer, a thin film transistor, and a data line and a pixel electrode connected with the thin film transistor. The common electrode layer includes a touch driving electrode and a common electrode which are insulated and spaced apart from each other. The array substrate further includes a shielding layer, which shields a spacing region between the touch driving electrode and the common electrode corresponding to position of the data line, thereby greatly reducing noise generated when the source and the data line are being charged, and in turn enabling the touch and the display of the touch display panel to be performed simultaneously.

Abstract: There are provided an organic light emitting display device, a driving method thereof and a display apparatus. The organic light emitting display device includes an underlay substrate, and organic light emitting pixel units arranged in a matrix on the underlay substrate; wherein the respective organic light emitting units comprise at least two organic light emitting structures which have different light emitting colors, are disposed in cascades and insulated from each other, and a pixel circuit connected corresponding to the organic light emitting structures and configured to drive the organic light emitting structures to emit light. Since the respective organic light emitting pixel units comprise at least two organic light emitting structures which have different light emitting colors, are disposed in cascades, and are insulated from each other, when displaying, each organic light emitting pixel unit can display, in different frame pictures, grey scale effects of at least two colors according to applied signals. The display effect can be raised because each organic light emitting pixel unit can display more colors.

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.
