    Abstract: The present application provides an in-cell touch display panel, a driving method thereof, and a display device. At least two sub-pixels are a sub-pixel group, cathode layers of different sub-pixel groups are independent of each other, which is equivalent to that the cathode layer set as a whole surface in the prior art is segmented, one sub-pixel group corresponds to one segmented cathode layer, cathode layers of respective sub-pixel groups are connected through conductive lines to the driver chip, so that the cathode layer is reused as a self-capacitive touch control electrode, the driver chip detects a capacitance variation of the cathode layer through the conductive line corresponding thereto to determine a touch location, thus achieving the touch control function. In the in-cell touch display panel, signals outputted by the driver chip to respective signal terminals of a sub-pixel circuit and the cathode layer in a fourth stage are obtained by superimposing the same touch scanning signal on basis of signals outputted to the respective signal terminals and the cathode layer in a third stage, so that the operating state of each module in the sub-pixel circuit is the same as that in the third stage, which ensures normal display, therefore an in-cell touch display panel based on OLED panel is achieved.

    Abstract: Disclosed are a method and a device for discriminating a boundary of image, and a display panel, for effectively discriminating whether an image has a boundary and in which direction the boundary is. The method for discriminating the boundary of image comprises: receiving an image information to be discriminated to form a matrix of grayscale parameter values, and dividing, with a grayscale parameter value corresponding to a sub-image unit to be processed as a center, the matrix of grayscale parameter values into a n×n matrix and a (n+2)×(n+2) matrix (S101); determining respectively in the n×n matrix and the (n+2)×(n+2) matrix: a minimum gradient and a minimum standard deviation in a row direction, in a column direction, in a first diagonal direction, and in a second diagonal direction, dispersion with respect to the minimum standard deviation and dispersion with respect to the minimum gradient (S102; S103); outputting a first code value when the determined dispersion is greater than N multiples of a minimum corresponding thereto, outputting a second code value when the determined dispersion is smaller than the N multiples of the minimum corresponding thereto (S104); determining, based on an outputted code value, whether the image to be discriminated has a boundary and in which direction the boundary is (S105).
