In the above embodiment, since the NFC antenna is embedded in the preset area of the casing of the front casing of the terminal, the NFC antenna is located in the front casing of the terminal, away from the PCB main board and the battery, thereby reducing the influence on the performance of the antenna. At the same time, since the NFC antenna and the casing can be integrated, the conventional installation method of the NFC antenna is reduced, that is, the contact of the terminal rear shell housing due to disassembly and the like is poor, and the stability is high. In a specific implementation process, as shown in FIG. 4, the NFC antenna 3 may be built in the frame region 4 of the touch panel of the casing 1. It should be noted that, in the specific implementation process, the frame area 2 and the frame area 4 may partially overlap or may completely overlap. That is to say, in actual use, the NFC antenna 3 may be disposed in the frame region 2 or the frame region 4. In a specific implementation, the NFC antenna includes a plurality of symmetric turns, which are etched on the touch screen panel, specifically a non-visible area of the edge of the touch screen panel. As shown in FIG. 4, the antenna is connected to a radio frequency circuit on the motherboard of the NFC terminal through an FPC 6 connector of the touch screen. It should be noted that the handheld device in this example is a mobile phone or a portable multimedia terminal. And the line of the NFC antenna is rectangular or other ring. The touch screen of the above embodiment may be a resistive touch screen or a capacitive touch screen or other screen panels with touch functions. When it is a resistive touch screen, as shown in FIG. 5, the resistive touch screen may include a plastic sheet layer 401, an upper transparent conductor layer 403, an isolation layer 405, a lower transparent conductor layer 407, and a glass layer 409 which are sequentially disposed from top to bottom. The NFC antenna 3 is disposed on any one of the plastic sheet layer 401, the upper transparent conductor layer 403, the isolation layer 405, the lower transparent conductor layer 407, and the glass layer 409. In a specific application process, the NFC antenna 3 is embedded in the preset area 2 of the casing 1 by one of the following methods, and is vapor-deposited, etched, sprayed, and pasted. In a specific implementation, the NFC antenna 3 can also be embedded in the frame region 4 by the above process. In the preferred implementation process, the etching process may be preferred because of the better stability of the etching process. In a specific application, if the casing 1 is made of a metal material, the NFC antenna 3 is provided with an insulating member outside. Of course, the casing 1 may be made of an insulating material such as glass or resin, and the outer portion of the NFC antenna 3 does not necessarily have to be provided with an insulating member. Since the above-mentioned housing 1 is generally used in combination with a terminal in a specific application process, the present embodiment provides a terminal including the above-described housing. In a preferred implementation, the feed line of the NFC antenna 3 described above is connected to the NFC chip located inside the terminal through a connector on the main board of the terminal. In order to better understand the above embodiments, the following detailed description will be made in conjunction with the accompanying drawings and specific examples. Since the touch screen is generally attached to the outer casing of the handheld device, it is generally divided into a see-through area 5 and a touch screen frame area 4, as shown in FIG. The perspective area 5 is generally the same size as the LCD display area, and is a transparent material, which is also an area used for actual touch; the touch screen frame area 4 is generally opaque, and the pasted adhesive is attached to this area; the coordinate signal and control of the touch screen The signal is led out by FPC and connected to the connector on the motherboard. The following is an example of a resistive touch display to illustrate the implementation of the NFC antenna of the present example: The general resistive touch screen is divided into five layers as shown in FIG. The resistive touch screen is composed of a plastic sheet layer 401, an upper transparent conductor layer 403, a spacer layer 405, a lower transparent conductor layer 407, a glass layer 409 and electrodes 411 at both ends from top to bottom, and the upper and lower electrodes are perpendicular to each other. The commonly used resistive touch display is controlled by four signal lines, which are led out by means of FPC. In order not to affect the use and appearance of the touch screen, in this example, the NFC antenna cable is placed in the frame area of the touch screen, the feeder line of the antenna is taken out through the FPC 6 of the touch screen, and then connected to the RF end of the NFC chip through a connector on the motherboard of the handheld device. The NFC antenna cable in this example is made of a metal material, and may be a single-ended type as shown in FIG. 1 or a differential type as shown in FIG. 2. In this example, the NFC antenna cable may be rectangular or may be Circular or other shaped annular structure. In this example, the NFC antenna coil can be embedded in the plastic sheet layer 401, the upper transparent conductor layer 403, the isolation layer 405, the lower transparent conductor layer 407, the glass layer 409, and the electrodes 411 at both ends. NFC day If the wire is placed on two conductor layers, the conductors of the turns and the conductor layer are insulated and not shorted to the conductor. In this example, the position of the NFC antenna coil is located in the border area 4 of the touch screen, and does not enter the perspective area 5 of the touch screen. In this example, the NFC antenna line may be placed on the touch screen by evaporation, etching, spraying or pasting. Corresponding layer; In this example, if the NFC antenna cable is single-ended, the wire leads to two feeders, and the two feeders of the wire are on the same FPC as the touch screen control line; in this example, NFC If the antenna line is differential, the line 圏 leads three feeders, and the three feeders of the line are on the same FPC as the touch screen control line. This example is described by taking a resistive touch screen as an example. The NFC antenna of the present invention can also be applied to a capacitive touch screen or other touch panel. The NFC antenna in this example can be composed of a plurality of symmetrical turns, which are etched inside the touch show, and the feeds of the turns are led out along with the touch screen coordinate control lines through the FPC. As a result of processing with the touch screen, the NFC antenna and touch screen as one integral part, one component is reduced. And the conventional NFC antenna is fabricated on the flexible circuit board substrate and then pasted on the structural member. This example saves the flexible circuit board. Since the etching process is consistent, and the feeder is in the form of a connector, the defects caused by the pasting or the like are avoided, and the stability of the antenna is enhanced. In addition, since the touch screen is at the top of the terminal and away from the main board PCB, the influence of the PCB on the antenna is reduced, and the appearance of the handheld device is not affected, and the space is fully utilized. From the above description, it can be seen that the present invention achieves the following technical effects: In the above embodiment, the housing of the NFC antenna and the front case of the terminal is applied as an integral component to the touch screen terminal, which greatly reduces the space of the terminal. Since the NFC antenna is at the top, it is easy to swipe the card, and the LCD is under the antenna, away from the PCB main board and battery, reducing the impact on the antenna performance. At the same time, the NFC antenna has good consistency, and the connection mode of the FPC and the connector avoids the high stability of the conventional NFC antenna due to poor contact during disassembly or use. It will be apparent to those skilled in the art that the various modules or steps of the present invention described above can be implemented in a conventional computing device, which can be centralized on a single computing device, or distributed. Alternatively, on a network of computing devices, they may be implemented by program code executable by the computing device such that they may be stored in the storage device by the computing device and, in some cases, The steps shown or described may be performed in an order different than that herein, or they may be separately fabricated into individual integrated circuit modules, or a plurality of the modules or steps may be implemented as a single integrated circuit module. Thus, the invention is not limited to any specific combination of hardware and software. The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
