The invention provides a display panel, a driving method and terminal equipment, the display panel comprises a driving chip, a touch screen and a touch capacitor, the touch screen comprises M driving electrode wires and M sensing electrode wires, and the touch capacitor is arranged at the intersection of the M driving electrode wires and the M sensing electrode wires; the driving chip provides N pulse signals for the M driving electrode wires and senses output signals of the touch capacitor through the M sensing electrode wires, the N pulse signals are pulse signals provided in one driving period, and N is a positive integer larger than M; wherein the M driving electrode wires comprise X first driving electrode wires, Q pulse signals in the N pulse signals are transmitted through the X first driving electrode wires, Q is smaller than N, and X is smaller than or equal to half Q. By means of the scheme, the touch point reporting rate of partial areas in a display panel screen can be increased, and therefore smoother and real-time control feeling is brought to a user.

This invention provides a touch display device and a driving method. The touch display device includes a touch driving circuit and a channel switching module. The touch driving circuit includes multiple touch channels, which are divided into multiple first touch channels and multiple second touch channels. The multiple first touch channels correspond to multiple first electrode blocks in a first touch area, and the multiple second touch channels correspond to and are connected to multiple second electrode blocks in a second touch area. The channel switching module is used to connect the corresponding connections between the multiple first touch channels and the multiple first electrode blocks, and disconnect the connections between the multiple first touch channels and the multiple second touch channels; or, it is used to disconnect the corresponding connections between the multiple first touch channels and the multiple first electrode blocks, and connect the connection between the first touch channel receiving the touch detection signal and the corresponding second touch channel in the scanning direction. This invention can be used to achieve a high touch reporting rate in a local area, improving the user experience.

The present application provides a touch display device, which includes a touch layer and a display panel, wherein the touch layer is located on the light-emitting side of the display panel, the display panel includes a plurality of sub-pixels, the touch layer includes a plurality of touch units, and each touch unit includes: a first electrode electrically connected in a first direction through a first connecting portion, the width of the first connecting portion in a direction perpendicular to the extension of the first connecting portion is greater than or equal to the width of three sub-pixels, and the first connecting portion and the first electrode are arranged in the same layer. Compared with the conventional technology, by making the first connecting portion surround at least three sub-pixels in a direction perpendicular to the extension of the first connecting portion, the impedance of the first connecting portion is reduced, thereby effectively reducing the resistance-capacitance delay of the first electrode conducting the electrical signal, increasing the touch scanning frequency, and facilitating the improvement of the touch reporting rate.
