[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the protection scope of the present disclosure.

Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0067] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components.

[0068] In touch panels, the integrity of the electrode pattern directly impacts the pattern's electrical parameters. Factors such as the screen display area size, pixel size, touch pattern unit size, and screen perforation can affect the integrity of the electrode pattern at the screen's edges. Often, an incomplete electrode pattern at the edge can affect touch performance.

[0069] In view of this, see FIG. 1A 、 FIG. 2 、 FIG. 3A 、 FIG. 3B and FIG. 4 As shown, FIG. 2 for FIG. 1A A schematic cross-sectional view along the dotted line D-D1 is shown in FIG. FIG. 3A for FIG. 1A The enlarged schematic diagram of the dotted box 220 in FIG. FIG. 3B for FIG. 1A An enlarged schematic diagram of the touch pattern 221 without missing areas, FIG. 4 for FIG. 1A FIG. 1 is an enlarged schematic diagram of a touch pattern 221 having a missing area in FIG. 1 . The embodiment of the present disclosure provides a touch display panel, which includes:

[0070] The base substrate 1 includes a display area A and a peripheral area B surrounding the display area A;

[0071] The touch metal layer 2 includes a touch pattern 221 located at least partially in the display area A, and a touch wire 222 located in the peripheral area B. The touch pattern 221 includes a plurality of sub-pattern blocks 23, and at least one floating electrode 24 is arranged in each sub-pattern block 23. The touch pattern 221 with the missing area Q is referred to as a missing touch pattern 2210. In the sub-pattern block 23 in which the missing area Q is located, the at least one floating electrode 24 is integrally electrically connected with the sub-pattern block 23. Specifically, for example, FIG. 4 In the sub-pattern block 23 on the left side (i.e., the side close to the peripheral area B) of the missing touch pattern 2210, the missing area Q exists. Therefore, the floating electrode 24 in the left sub-pattern block 23 can be integrally electrically connected with the sub-pattern block 23. Specifically, the touch metal layer 2 can include the touch pattern 221 located in the display area A, and the touch pattern 221 located outside the display area A. That is, the touch pattern 221 can have a portion extending beyond the AA edge, so as to ensure better touch effect.

[0072] In the embodiments of the present disclosure, for the touch pattern 221 with the missing area Q, the at least one floating electrode 24 in the sub-pattern block 23 in which the missing area Q is located is integrally electrically connected with the sub-pattern block 23. The effective area of the edge touch pattern 221 is compensated, and the self-capacitance of the incomplete missing touch pattern 2210 is improved. In this way, the electrical parameters of the missing touch pattern 2210 at the edge of the screen are optimized, and the touch performance of the edge of the screen is improved. Specifically, the self-capacitance can be understood as the capacitance of the missing touch pattern 2210 to the ground.

[0073] Specifically, the floating electrode 24 can be understood as a structure in which only an electrode pattern is arranged, and no electrical signal is loaded to the electrode pattern in the use process. In the embodiments of the present disclosure, after the floating electrode 24 is integrally electrically connected with the sub-pattern block 23, the floating electrode 24 becomes an integrated structure with the sub-pattern block 23, and can load the same signal as the sub-pattern block 23. The floating electrode 24 which is not integrally electrically connected with the sub-pattern block 23 can still maintain the original function of the floating electrode, i.e., only an electrode pattern is arranged, and no electrical signal is loaded in the use process.

Specifically, the first touch electrode F1 can be a transmitting electrode Tx, and the second touch electrode F2 can be a receiving electrode Rx. The first touch electrode F1 and the second touch electrode F2 are in the same layer and are insulated from each other. Specifically, in the embodiment of the present disclosure, a mutual-capacitance touch can be formed by the first touch electrode F1 and the second touch electrode F2.

[0075] In a possible implementation, in combination with FIG. 1A 、 FIG. 1B As shown, the touch lead 222 includes a first touch lead 223 electrically connected to the first touch electrode F1, and a second touch lead 224 electrically connected to the second touch electrode F2.

[0077] Specifically, the area of the normal touch pattern 2210 in the orthographic projection of the substrate 1 is less than the area of the normal touch pattern 221 without missing in the orthographic projection of the substrate 1.

[0078] In specific implementation, the missing area Q can be located at different positions of the missing touch pattern 2210, and accordingly, the floating electrode 24 at different positions needs to be electrically connected to the corresponding sub-pattern block 23, which will be described below.
