The invention discloses a touch panel, a touch display panel and a touch display device and belongs to the technical field of display. The touch panel comprises a first substrate, multiple first electrodes, multiple second electrodes, a second substrate and multiple third electrodes, wherein the multiple first electrodes are arranged on a first surface of the first substrate in parallel at intervals and extend in a first direction; the multiple second electrodes are arranged on the first surface in parallel at intervals, are insulated from the multiple first electrodes and extend in a second direction, and the second direction and the first direction intersect; the second substrate is fixedly connected with the first substrate and parallel to the first substrate, and has a second surface opposite to the first surface; the multiple third electrodes are arranged on the second surface in parallel at intervals and extend in the second direction; the second electrodes and the third electrodes are alternately arranged in the second direction, and in a direction perpendicular to the first substrate, a plane where the second electrodes are located is parallel to a plane where the third electrodes are located. According to the touch panel, the touch display panel and the touch display device, floating touch is realized.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel, a touch display panel and a touch display device. Background technique [0002] Capacitive touch screen is currently the most widely used touch screen. Capacitive touch screens can be divided into mutual capacitance and self capacitance. Compared with the self-capacitive touch screen, the mutual capacitive touch screen has the advantages of supporting multi-touch, high light transmittance, low power consumption, and long life, so it is more widely used. [0003] In the existing mutual capacitance touch screen, the coordinates of the touch point are determined through the change of mutual capacitance generated when the human hand approaches the touch screen. Since there is environmental interference around the touch screen, in order to prevent false touches, only when the capacitance change value reaches the set value will the touch be triggered. When th...
