Abstract

The invention discloses a touch and control display panel and touch and control device, a touching and control display panel comprises a plurality of a second touch a control electrode; a self mutual capacitance switching circuit, comprises: a first control signal line, which is used to control self mutual capacitance switching circuit to select the self-capacitance detection model or capacitance detection model; a first thin film transistor unit, each the first thin film transistor unit comprises a first thin film transistor and a second thin film transistor; a first electrode of the first film transitory and a first electrode of the second thin film transistor from the same the first film transistor unit are electrically connected with a first and a second touch and control electrode each the first film transistor and the grid of the second film transistor connected electrically with the first control signal line; a second electrode of the first film transistor is electrically connected with a mutual capacitance signal line; the second electrode of the second film transistor is connected electrically with the self capacitance signal line. The self mutual capacitance switching circuit makes the touch control panel switch from the self capacitance detection model to the mutual detection model.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel and a touch display device including the touch display panel. Background technique [0002] With the rapid development of display technology, touch display technology has gradually pervaded people's lives. Among the existing touch display panels, compared with resistive touch display panels, capacitive touch display panels have the advantages of long life, high light transmittance, and support for multi-touch, and have become a hot spot in touch display technology. . [0003] Capacitive touch display panels can be classified into self-capacitive touch display panels and mutual-capacitive touch display panels. The self-capacitive touch display panel is composed of horizontal electrodes and vertical electrodes. When detecting the user's touch, the self-capacitive touch display panel scans the horizontal electrodes and the vertical electrodes resp...
