[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0026] The fingerprint recognition module 100 according to a first aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figures 1 to 3 As shown, according to the fingerprint recognition module 100 of the first aspect embodiment of the present invention, the fingerprint recognition module 100 has a fingerprint recognition surface 1 and an outer peripheral side surface 2 surrounding the outer periphery of the fingerprint recognition surface 1, and the intersection of the fingerprint recognition surface 1 and the outer peripheral side surface 2 is rounded 3. That is, by the processing technology of rounding 3, the sharp corner between the fingerprint recognition surface 1 and the outer peripheral side surface 2 is cut into an arc surface, so that the fingerprint recognition surface 1 and the outer peripheral side surface 2 can smoothly transition along the arc.

[0028] It is understandable that when a user needs to use the fingerprint recognition module 100, they need to place their finger on the fingerprint recognition surface 1 so that the chip of the fingerprint recognition module 100 can recognize it. However, when the outer peripheral edge of the fingerprint recognition surface 1 is formed into a sharp structure such as a right angle, the sharp structure can easily scratch the user's finger when the finger moves on or across the fingerprint recognition surface 1.

[0029] Therefore, by rounding the corner 3 at the intersection of the fingerprint recognition surface 1 and the outer peripheral side 2, the fingerprint recognition surface 1 can smoothly transition with the outer peripheral side 2 along an arc to avoid sharp structures such as right angles on the outer peripheral edge of the fingerprint recognition surface 1. This avoids the risk of sharp structures scratching the user and improves the security of the fingerprint recognition module 100. The rounding corner 3 process is relatively mature and can reduce the difficulty of processing a smooth transition between the fingerprint recognition surface 1 and the outer peripheral side 2.

[0030] Furthermore, the radius of the rounded corner 3 at the intersection of the fingerprint recognition surface 1 and the outer peripheral side 2 ranges from 0.5mm to 2.0mm. For example, the radius of the rounded corner 3 (e.g.) Figure 3 The radius R shown can be 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.3mm, 1.6mm, 2.0mm, etc., and no specific limitation is made here. With the width of the rounded corner 3 area fixed, a radius that is too small will increase the processing difficulty of the rounded corner 3. Furthermore, both excessively small and excessively large radii of the rounded corner 3 will reduce the smoothness of the transition between the rounded corner 3 area and the fingerprint recognition surface 1 and the outer peripheral side 2. Therefore, by controlling the radius of the rounded corner 3 within the range of 0.5mm to 2.0mm, the smoothness of the transition between the rounded corner 3 area and the fingerprint recognition surface and the outer peripheral side 2 can be better guaranteed, thus avoiding the risk of scratching the user's fingers.

[0031] According to the fingerprint recognition module 100 of the first aspect of the present invention, by rounding the corner 3 at the intersection of the fingerprint recognition surface 1 and the outer peripheral side 2 and controlling the radius of the rounded corner 3 within the range of 0.5mm to 2.0mm, the fingerprint recognition surface 1 and the outer peripheral side 2 can smoothly transition along an arc to avoid sharp structures such as right angles on the outer peripheral edge of the fingerprint recognition surface 1, thereby avoiding the risk of sharp structures scratching the user and improving the security of the fingerprint recognition module 100.

[0032] In some embodiments, the rounded corner 3 is a ring extending along the outer periphery of the fingerprint recognition surface 1, so as to ensure that the outer periphery edge of the fingerprint recognition surface 1 can form a smooth transition with the corresponding outer periphery side 2.

[0033] According to some embodiments of this utility model, in the width direction of the fingerprint recognition module 100, the ratio of the width W1 of the fingerprint recognition surface 1 to the width W2 of the fingerprint recognition module 100 ranges from 0.6 to 0.8. It can be understood that the larger the ratio of the width of the fingerprint recognition surface 1 to the width of the fingerprint recognition module 100, the larger the area of ​​the fingerprint recognition surface 1, resulting in higher accuracy for fingerprint recognition, but a smaller arrangement space reserved for the rounded corners 3; conversely, the smaller the ratio of the width of the fingerprint recognition surface 1 to the width of the fingerprint recognition module 100, the larger the arrangement space reserved for the rounded corners 3, the lower the processing difficulty, but a smaller area of ​​the fingerprint recognition surface 1.

[0034] Therefore, by controlling the ratio of the width W1 of the fingerprint recognition surface 1 to the width W2 of the fingerprint recognition module 100 within the range of 0.6 to 0.8, it is possible to ensure that the fingerprint recognition surface 1 has sufficient area while reserving ample space for the rounded corner 3 between the fingerprint recognition surface 1 and the outer peripheral side 2. The ratio of the width of the fingerprint recognition surface 1 to the width of the fingerprint recognition module 100 can be 0.6, 0.62, 0.65, 0.68, 0.7, 0.73, 0.76, 0.8, etc.

[0035] According to some embodiments of this utility model, the fingerprint recognition surface 1 is an arc-shaped surface. Wherein, with the same projected area, the arc-shaped surface has a larger surface area compared to a flat surface. Therefore, the area of ​​the fingerprint recognition surface 1 can be significantly increased, thereby increasing the contact area between the fingerprint recognition module 100 and the user's finger, and thus improving the speed and accuracy of the fingerprint recognition module 100 in recognizing the user's fingerprint.

[0036] According to some embodiments of this utility model, the fingerprint recognition surface 1 is a concave arc-shaped surface. That is, the fingerprint recognition surface 1 is recessed towards the interior of the fingerprint recognition module 100. It can be understood that the surface of a finger is usually a convex arc-shaped surface. Therefore, by setting the fingerprint recognition surface 1 as a concave arc-shaped surface, the fit between the surface of the finger and the fingerprint recognition surface 1 can be improved, thereby improving the recognition accuracy of the fingerprint recognition surface 1.

[0037] It should be noted that this description is only of one type of fingerprint recognition surface 1 shape and is not a limitation on the shape of the fingerprint recognition surface 1. For example, in some other embodiments, the fingerprint recognition surface 1 may also be a convex arc surface; or, the fingerprint recognition surface 1 may also be an arc surface combining convex and concave surfaces, etc., without specific limitations.

[0038] According to some embodiments of the present invention, at least a portion of the fingerprint recognition module 100 is provided with a texture layer, on which textures are formed. The textures on the texture layer can be regular or irregular patterns, without specific limitations. By providing a texture layer, the recognizability of the fingerprint recognition module 100 can be improved, making it easier for users to identify whether they are using the fingerprint recognition module 100. Furthermore, by drawing the shape of the texture layer, the monotonous appearance of the fingerprint recognition module 100 can be improved, thereby enhancing the user experience. In some embodiments, the textures on the texture layer can be three-dimensional textures, and the reflection of light from the three-dimensional textures can reflect different color effects, thereby enhancing the aesthetics of the fingerprint recognition module 100.

[0039] In some embodiments, the texture layer at least covers the fingerprint recognition surface 1.

[0040] In other embodiments, the texture layer at least covers the rounded corner 3 region.

[0041] According to some embodiments of this utility model, a protective layer is provided on the outer side of the textured layer. This protective layer provides good protection for the textured layer, preventing damage from friction and contact with the external environment. In some embodiments, the protective layer can be made of a wear-resistant material, meaning it has good wear resistance to ensure its protective effect on the textured layer. Furthermore, the protective layer is optically transparent, thus preventing it from affecting the display effect of the textured layer.

[0042] According to some embodiments of this utility model, the projection of the fingerprint recognition module 100 onto the reference surface is a rounded rectangle. This effectively avoids sharp edges on the outer peripheral side 2; in other words, the outer peripheral side 2 is formed as a smooth curved surface, thus better preventing sharp edges from scratching the user and further improving the security of the fingerprint recognition module 100.

[0043] According to some embodiments of this utility model, the length L and width W2 of the fingerprint recognition module 100 satisfy the following condition: 6 ≤ L / W2 ≤ 8. It can be understood that, with a fixed width, a smaller ratio of length to width results in a smaller installation space occupied by the fingerprint recognition module 100, but also a smaller area of ​​the fingerprint recognition surface 1; conversely, a larger ratio results in a larger fingerprint recognition surface 1 area, but also a larger installation space occupied by the fingerprint recognition module 100.

[0044] Therefore, by controlling the ratio of the length to the width of the fingerprint recognition module 100 within the range of 6 to 8, the installation space occupied by the fingerprint recognition module 100 can be controlled while ensuring the area of ​​the fingerprint recognition surface 1 to improve recognition accuracy. For example, the ratio of the length to the width of the fingerprint recognition module 100 can be 6, 6.2, 6.5, 6.8, 7, 7.3, 7.6, 8, etc.

[0045] According to some embodiments of this utility model, the projection of the fingerprint recognition module 100 onto the reference surface is a rounded rectangle, and the length L and width W2 of the fingerprint recognition module 100 satisfy: 6≤L / W2≤8. This improves the security of the fingerprint recognition module 100 and, while ensuring the area of ​​the fingerprint recognition surface 1 to improve recognition accuracy, controls the installation space occupied by the fingerprint recognition module 100.

[0046] An electronic device according to a second aspect of the present invention will now be described with reference to the accompanying drawings.

[0047] An electronic device according to a second aspect embodiment of the present invention includes: a housing and a fingerprint recognition module 100, wherein the fingerprint recognition module 100 is disposed on the housing. The electronic device can be a mobile device such as a mobile phone, tablet, watch, or computer that can be equipped with the fingerprint recognition module 100; no specific limitation is made here regarding the specific type of electronic device.

[0048] According to the second aspect of the present invention, the electronic device, by rounding the corner 3 at the intersection of the fingerprint recognition surface 1 and the outer peripheral side 2 and controlling the radius of the rounded corner 3 within the range of 0.5mm to 2.0mm, allows the fingerprint recognition surface 1 to smoothly transition with the outer peripheral side 2 along an arc to avoid sharp structures such as right angles on the outer peripheral edge of the fingerprint recognition surface 1, thereby avoiding the risk of sharp structures scratching the user and improving the security of the fingerprint recognition module 100.

[0049] According to some embodiments of this utility model, the fingerprint recognition surface 1 is higher than the outer surface of the housing. Therefore, the outer surface of the housing can be avoided from obstructing the user's finger, so that the user's finger can fit against the fingerprint recognition surface 1, thereby improving the recognition accuracy of the fingerprint recognition module 100.

[0050] According to some embodiments of this utility model, the outer shell includes an outer peripheral frame, and the fingerprint recognition module 100 is disposed on the outer peripheral frame. Therefore, when a user uses the electronic device, their finger can be easily placed on the fingerprint recognition module 100 on the outer peripheral frame, thereby reducing the difficulty for the user to use the fingerprint recognition module 100.

[0051] According to some embodiments of this utility model, the fingerprint recognition surface 1 is higher than the outer surface of the housing, the housing includes an outer peripheral frame, and the fingerprint recognition module 100 is disposed on the outer peripheral frame. Therefore, while improving the recognition accuracy of the fingerprint recognition module 100, the difficulty for users to use the fingerprint recognition module 100 can be reduced.
