[0032] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0033] The following Figures 1 - 8 describes an NFC antenna installation structure of a handheld terminal of the present invention, including a front shell 100, a TP cover plate 200, an LCD component 300 and an NFC antenna 400.

[0034] Among them, an LCD mounting groove 101 is provided on the front shell 100. An NFC avoidance groove 102 is provided around the outer peripheral side of the LCD mounting groove 101. A TP cover plate mounting groove 103 is provided around the outer peripheral side of the NFC avoidance groove 102.

[0035] Specifically, the LCD mounting groove 101, the NFC avoidance groove 102, and the TP cover plate mounting groove 103 are communicated. The sinking depths of the LCD mounting groove 101, the NFC avoidance groove 102, and the TP cover plate mounting groove 103 decrease in sequence. That is to say, the LCD mounting groove 101, the NFC avoidance groove 102, and the TP cover plate mounting groove 103 are distributed in a stepped shape on one side edge. In some embodiments, the LCD mounting groove 101, the NFC avoidance groove 102, and the TP cover plate mounting groove 103 are only distributed in a stepped shape on the left and right sides respectively, while on the upper and lower sides, the sinking depths of the NFC avoidance groove 102 and the LCD mounting groove 101 are the same.

[0036] More specifically, in order to facilitate the connection of the TP cover plate 200 to the front shell 100, a dispensing groove 104 is provided by sinking the bottom end face of the TP cover plate mounting groove 103. The dispensing groove 104 can be designed as an elongated sunken groove structure with a relatively shallow sinking depth, and is approximately located at 0.8 - 1.0 millimeters from the side wall of the TP cover plate mounting groove 103.

[0037] The TP cover plate 200 is horizontally arranged across the upper sides of the LCD mounting groove 101 and the NFC avoidance groove 102, and the side edges are located in the TP cover plate mounting groove 103 to enclose the LCD mounting groove 101 and the NFC avoidance groove 102. The TP cover plate 200 refers to the protection cover plate of the Touch Panel, which is a transparent material such as glass or plastic used to cover the touch screen to protect the touch screen from physical damages such as scratches and impacts.

[0038] Furthermore, a first OCA glue layer 201, a touchable layer 202, and a second OCA glue layer 203 are sequentially arranged on the side of the TP cover plate 200 facing the LCD component 300. The above several components form a TP component. The side edges of the TP component are connected in the TP cover plate mounting groove 103 by means of dispensing. The existence of the dispensing groove 104 facilitates the dispensing work. Among them, OCA glue is the abbreviation of Optically Clear Adhesive, which is a special adhesive used for bonding transparent optical elements and is usually used for material bonding on the touch screen.

[0039] The LCD component 300 is disposed on the side of the TP cover plate 200 facing the LCD mounting groove 101, and the LCD component 300 is located within the LCD mounting groove 101. Among them, the LCD component 300 includes an LCD screen 301 and a screen FPC 302 (FPC stands for Flexible Printed Circuit, a flexible printed circuit board). The front surface of the LCD screen 301 is connected to the TP cover plate 200, and the screen FPC 302 is disposed on the back surface of the LCD screen 301.

[0040] Specifically, the front surface of the LCD screen 301 is adhered to the second OCA adhesive layer 203, and the screen FPC 302 is electrically connected to the main board (not shown in the figure) through corresponding connectors to ensure the electrical conduction of the LCD screen 301.

[0041] The NFC antenna 400 is disposed around the outer peripheral side of the LCD component 300 and is connected to the TP cover plate 200. The NFC antenna 400 is located within the NFC avoidance groove 102.

[0042] Specifically, the NFC antenna 400 includes an antenna body 401 and a connecting piece 402. The antenna body 401 is in a rectangular structure and surrounds the outside of the LCD screen 301. The front surface of the antenna body 401 is connected to the TP cover plate 200. When the side of the TP component is connected within the TP cover plate mounting groove 103, the antenna body 401 is located within the NFC avoidance groove 102. Among them, the antenna body 401 is connected to the first end of the connecting piece 402, and the second end of the connecting piece 402 is bent towards the side of the screen FPC 302 and is connected to the screen FPC 302.

[0043] Furthermore, the front surface of the antenna body 401 is adhered to the second OCA adhesive layer 203, and the back surface of the antenna body 401 is covered with a ferrite layer 403 to enhance the magnetic field generated by the coil, thereby improving the efficiency and range of NFC communication. The second end of the connecting piece 402 is provided with a pad to facilitate the soldering of the connecting piece 402 and the screen FPC 302 during installation, so that the circuit of the NFC antenna 400 is electrically connected.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
