  • Touch display panel and touch display device
    Patent number: 11768397
    Abstract: A touch display panel has a first region and a second region. The touch display panel includes a first touch unit located in the first region, and a plurality of second touch units located in the second region, wherein the plurality of second touch units is arranged in a matrix in a first direction and a second direction, the first direction intersecting the second direction. An area of an orthographic projection of the first touch unit on a plane of the touch display panel is smaller than an area of an orthographic projection of one second touch unit of the plurality of second touch units on the plane of the touch display panel. An absolute value of a difference between an impedance of the first touch unit and an impedance of the one second touch unit is smaller than a first preset threshold.
