For example, the first transparent substrate may also be referred to as a second transparent substrate without departing from the scope of the embodiments of the present application. Similarly, the second transparent substrate may also be referred to as a first transparent substrate.

A transparent cover provided by each embodiment of the present application can be applied to a terminal.

An adhesive layer (not shown) is disposed between the fingerprint touch electrode layer and the second surface 1012 of the first transparent substrate 101. The fingerprint touch electrode layer and the first transparent substrate 101 are in contact with the adhesive layer. .

As shown in FIG. 1 or FIG. 2 , as an example, the fingerprint touch electrode layer may be added on the first surface 1021 of the second transparent substrate 102 by using an ink spraying process, and then the fingerprint touch electrode layer may be added. The second transparent substrate 102 is adhered to the recess 104 by using a transparent glue such as an optical adhesive, so that the second transparent substrate 102 after the fingerprint touch electrode layer is added is bonded to the second surface 1012 of the first transparent substrate 101.

The fingerprint touch electrode layer and the second transparent substrate 102 are in contact with the adhesive layer. .

Wherein, as an example, the fingerprint touch electrode layer may be added on the second surface 1012 of the first transparent substrate 101 by using an ink spraying process, and then the second transparent substrate 102 may be bonded with a transparent glue, such as an optical glue. The first transparent substrate 101 after the fingerprint touch electrode layer is bonded to the first surface 1021 of the second transparent substrate 102 is bonded to the recess 104 of the first transparent substrate 101 after the fingerprint touch electrode layer. The layer formed of the above transparent glue is the above-mentioned adhesive layer.

The thickness of the fingerprint touch electrode layer may be 0.05 micrometers (μm) or 0.1 μm.

Further, FIG. 3 is a cross-sectional view of another transparent cover 100 according to an embodiment of the present application. As shown in FIG. 3, the transparent cover 100 may further include a Flexible Printed Circuit (FPC) 105.

The first end of the FPC 105 (shown as 1051 in FIG. 3) may be electrically connected to the fingerprint module layer 103, and the second end (such as 1052 shown in FIG. 3) may be used for driving the circuit board (FIG. 3). The electrical connection is not shown, so that the driving circuit board drives the fingerprint module layer 103 through the FPC 105 to collect the fingerprint information of the user.

When the transparent cover 100 is formed, the FPC 105 may be attached to the fingerprint module layer 103 after the fingerprint module layer 103 is disposed on the second surface 1012 of the first transparent substrate 101 or the first surface 1021 of the second transparent substrate 102.

In a possible implementation manner, the size (such as the width or length) of the fingerprint module layer 103 and the second transparent substrate 102 may be slightly smaller than the size of the groove 104, such that the groove 104 and the second transparent module 102 are There is a trace space between at least one side edge, and the first end of the FPC 105 (such as 1051 shown in FIG. 3) is electrically connected to the fingerprint module layer 103, and the second end (such as 1052 shown in FIG. 3) can be It is taken out from the wiring space to connect the driving circuit board.

There may be a certain gap between the second surface 1021 of the first transparent substrate 101, and the gap may form the dispensing groove 106.

Wherein, the dispensing tank 106 can be used to fill the adhesive. For example, the adhesive can be a high strength glue. After the fingerprint module layer 103 and the second transparent substrate 102 are embedded in the recess 104, high-strength glue can be added to the dispensing tank 106, so that the first transparent substrate 101 and the second transparent substrate 102 and the fingerprint module can be made. The bond between the layers 103 is more stable and acts as a reinforcement.

Further, FIG. 4 is a cross-sectional view of another transparent cover 100 according to an embodiment of the present application. As shown in FIG. 4, in the embodiment of the present application, the edge of the first surface 1011 of the first transparent substrate 101 has a curved surface structure 107.

Wherein, since the second surface 1012 of the first transparent substrate 101 is provided with the groove 104, the first transparent substrate 101 has a structure with a thin intermediate thickness. In this way, when the user places a finger on the display screen of the terminal including the transparent cover 100, the thinner area in the middle of the first transparent substrate 101 can ensure that the distance between the user's finger and the fingerprint module layer 103 is relatively short, thereby Make sure the terminal can collect clearer fingerprint information. In addition, the circumference of the first transparent substrate 101 is thick, which greatly contributes to the reliability of the transparent cover 100, and the edge thereof can also be processed by a curved processing technique to form a curved surface shape, so that the terminal including the transparent cover 100 is used. The appearance is more beautiful. For example, at least one edge of the first surface 1011 of the first transparent substrate 101 may be subjected to a curved surface processing using a 2.5D arc surface processing technique to generate a transparent substrate having a 2.5D curved surface structure. For another example, the first surface 1011 of the first transparent substrate 101 may be subjected to a curved surface processing by a 3D arc surface processing technique to form a transparent substrate having a 3D curved surface structure.

It should be noted that the position and size of the groove 104 shown in any one of FIGS. 1 to 4 in the second surface 1012 of the first transparent substrate 101 is only an example. In a practical application, the position and the size of the groove in the second surface of the first transparent substrate may be set according to the requirements of the area and the size of the fingerprint identification according to the actual application scenario. The position and size in the second surface of the transparent substrate are not specifically limited. Moreover, the size of the second transparent substrate may also be adaptively adjusted according to the size of the groove provided in the second surface of the first transparent substrate.

Referring to FIG. 5 or FIG. 6, for the transparent cover 200, as shown in FIG. 7, is a top view of the first transparent substrate 201, wherein the area indicated by the broken line in FIG. 7 indicates that the groove 204 is on the first transparent substrate. 201 is located in the second surface 2012 and the size of the groove 204. It should be noted that FIGS. 5 and 6 are cross-sectional views of the transparent cover 200 taken along line BB' shown in FIG.
