    摘要： 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, 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 such that each sub-pixel circuit operates in the fourth phase in the same state as in the third phase. Thereby the capacitance of the self-capacitance electrodes remains unchanged before and after application of the touch scanning signal in the case that the touch screen panel is not touched by a human body.

    摘要： The disclosure provides a detection circuit, a detection method and a drive system. The detection circuit comprises a switching unit, a reset unit and a comparison unit. The switching unit is used for switching the operations of the reset unit and the comparison unit. The reset unit is used for resetting the acquisition unit before the acquisition unit begins acquisition. The comparison unit is used for comparing a signal acquired by the acquisition unit with a standard signal to obtain a characterization quantity of the to-be-detected voltage. The detection circuit can detect a representative quantity of a threshold voltage of a drive transistor or a working voltage of a light emitting element in a pixel circuit, and thereby can detect non-uniformity of display brightness of pixels inside an active matrix organic electroluminescence display device. In turn, an external compensation circuit is enabled to well compensate the display brightness of pixels according to the detection result, such that the uniformity of display and hence the display effect of the active matrix organic electroluminescence display device is improved.
