Generally, the middle area of the touch panel 10 is used as the display area 15 , and the non-display area 16 is arranged around the display area 15 . For example, the non-display area 16 is provided on the top side or the bottom side of the display area 15

Since the touch panel 10 is made of light-transmitting material, the user can check the content displayed on the screen of the terminal 1000 through the display area 15 .

In order to make the terminal 1000 more beautiful, ink can be sprayed on the lower surface 14 of the non-display area 16. The color of the ink is, for example, white, black or blue, which can be set according to actual needs. The ink can not only meet the user's requirements for different colors of the terminal 1000, but also can cover the internal structure of the terminal 1000 to achieve the effect of beautifying the terminal 1000.

It can be understood that the shape of the touch panel 10 may be specifically designed according to the shape of the terminal 1000, for example, a rectangle with rounded corners.

For example, CNC (Numerical Control Machining) technology is used to cut off material at a joint between the side surface 3112 and the bottom surface 3111 to form the recessed portion 33 .

In a practical application, when the user operates to unlock the terminal 1000 with a fingerprint, the user may place a finger on a position corresponding to the fingerprint chip 310 . The signal of the fingerprint chip 310 passes through the package body 311 to collect and identify the user's fingerprint pattern, and the user's fingerprint pattern is matched with the pre-stored fingerprint pattern, and if the matching is successful, the terminal 1000 is unlocked.

It can be understood that the surface of the fingerprint chip 310 facing the user's finger is provided with a sensing pixel array to collect the user's fingerprint pattern. Encapsulating the fingerprint chip 310 in the packaging body 311 can reduce the influence of other interference signals on the sensing pixel array when collecting fingerprint patterns, so as to improve the accuracy of identification.

In the embodiment of the present invention, forming the recessed portion 33 in the package body 311 can not only reduce the thickness of the fingerprint chip package structure 31, but also reserve a design space for the screen flexible circuit board 18 in the thickness direction, therefore, it can be assembled during assembly. The recess 33 is attached to the screen flexible circuit board 18, and the fingerprint chip packaging structure 31 and the screen flexible circuit board 18 partially overlap in the thickness direction, so that the fingerprint chip packaging structure 31 is arranged closer to the display area 15 to reduce non-display The ratio of the area of the area 16 to the area of the touch panel 10 increases the ratio of the area of the display area 15 to the area of the touch panel 10, and compared with the prior art, the design length of the terminal can be reduced.

The package body 311 can be formed by cutting off the material on the package body 311 to form the concave portion 33 , or can be formed by connecting the first package part 314 and the second package part 315 . It can be understood that, in order to form the concave portion 33 , the maximum cross-sectional area of the first packaging portion 314 is smaller than the minimum cross-sectional area of the second packaging portion 315 .

In some embodiments, the circuit contacts of the fingerprint chip 310 are easily exposed to connect with the fingerprint flexible circuit board 32 .

In some embodiments, the shape and size of the first packaging part 314 match the shape and size of the fingerprint recognition chip 310 .

In other words, the shape of the fingerprint chip 310 is similar or the same as that of the first encapsulation part 314 , for example, the fingerprint chip 310 is in the shape of a cuboid, and the shape of the first encapsulation part 314 is in the shape of a cuboid or a rounded cuboid.

The size of the first packaging part 314 is slightly larger than that of the fingerprint chip 310 to achieve the effect of packaging the fingerprint chip 310 . Therefore, this can make the structure of the fingerprint chip packaging structure 31 more compact.
