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.

The present application claims to the benefit of Chinese Patent Application No. 202211310755.2, filed on Oct. 25, 2022, the content of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of display technologies, and in particular, to a touch display panel and a touch display device.
With the rapid development of display technology and human-computer interaction technology, display panels with touch function have been more and more widely used. For example, in order to achieve the purpose of convenience of carrying, light weight, and small size, an input device of many electronic products, such as the mobile phone, has changed from the traditional keyboard or mice and other devices for input to the touch screen.
In order to more clearly illustrate the embodiments of the present disclosure, the accompanying drawings used in the embodiments are briefly described below. The drawings described below are merely a part of the embodiments of the present disclosure. The accompanying drawings in the following description are some embodiments of the present disclosure, and other accompanying drawings can be obtained in accordance with these drawings for those skilled in the art.
FIG. 1 is a schematic diagram of a touch display panel according to embodiments of the present disclosure;
FIG. 2 is a schematic diagram of another touch display panel according to embodiments of the present disclosure;
For facilitating the understanding of the technical solution of the present disclosure, the embodiments of the present disclosure are described in detail below.
It should be understood that the embodiments described below are merely some of, rather than all of the embodiments of the present disclosure. On a basis of the embodiments in this disclosure, all other embodiments obtained by the ordinary skilled in the art without paying creative effort are within a protection scope of this disclosure.
The terms used in the embodiments of the present disclosure are merely for the purpose of describing specific embodiments, but not intended to limit the present disclosure. The singular forms of “a”, “an” and “the” used in the embodiments of the present disclosure and the appended claims are also intended to indicate plural forms, unless clearly indicating others.
