From the above description, the beneficial effects of the present invention are: the thickness of the NFC antenna can be reduced, the thickness of a machine body can be reduced, and the spatial layout is optimized.
Further, the total thickness of the NFC antenna structure is less than or equal to 55 μ ι η.
Further, the thickness of the base material is 50 μm, and the thickness of the antenna coil is 5 μm.
As can be seen from the above description, the light transmittance of the screen is satisfied by thinning the antenna trace, so that the setting position of the NFC antenna structure is not limited to the non-display area.
Furthermore, the display panel also comprises a metal layer, and the metal layer is arranged on one surface of the back plate, which is far away from the display panel.
As can be seen from the above description, by disposing the metal layer under the back plate, the electromagnetic interference of the NFC antenna to other devices can be effectively avoided.
Further, the antenna coil is disposed adjacent to the cover glass.
Further, the touch panel comprises a light guide layer, a touch screen and an electronic ink screen which are arranged in a stacked mode.
The invention further provides terminal equipment which comprises a shell and the screen assembly, wherein the screen assembly is arranged in the shell.
Example one
Referring to fig. 1 to 8, a first embodiment of the present invention is: a screen component integrating an NFC antenna structure can be applied to terminal equipment needing to realize an NFC function, such as a POS machine, a Tag card and the like. The screen assembly comprises cover plate glass, a touch panel, a polarizing plate, a display panel and a back plate which are arranged in a stacked mode, and further comprises an NFC antenna structure.
As shown in fig. 1-2, the NFC antenna structure 1 includes a substrate 11 and an antenna coil 12, where the antenna coil 12 is disposed on the substrate 1. The shape, length, thickness, etc. of the antenna coil can be determined according to actual requirements and performance, for example, the self-inductance and resistance of the coil and the chip used can be designed. In this embodiment, the total thickness of the NFC antenna structure is 55 μm, wherein the thickness of the substrate is 50 μm, and the thickness of the antenna coil is 5 μm. Furthermore, the base material can be PET or glass, and the antenna coil is made of metal.
The NFC antenna structure may be disposed between any two adjacent layers of the screen assembly stack. For example, as shown in fig. 3, the NFC antenna structure 1 is disposed between the cover glass 2 and the touch panel 3; as shown in fig. 4, the NFC antenna structure 1 is disposed between the touch panel 3 and the polarizer 4; as shown in fig. 5, the NFC antenna structure 1 is disposed between the polarizer 4 and the display panel 5; as shown in fig. 6, the NFC antenna structure 1 is disposed between the display panel 5 and the back plate 6. Wherein, only the touch panel (liquid crystal display) has certain influence on the performance of the NFC antenna.
This embodiment is through thining antenna coil, can reach the effect of metal wiring transparence, and when integrated with the screen subassembly, the luminousness also can meet the demands, does not influence the screen display, consequently, NFC antenna structure's the position that sets up can not confine to the non-display area, and NFC antenna structure can set up the arbitrary region at the screen promptly.
The NFC coil generates a magnetic field after being electrified, the current direction can be controlled to enable the magnetic field to radiate the magnetic field outside the screen, and then the function is achieved through coupling. Fig. 7 is a schematic diagram of a magnetic field direction and a current direction of the NFC antenna structure of the present embodiment, where C is the magnetic field direction and radiates outward; d is the current flow direction, and E is the current flow direction.

When the NFC antenna structure is disposed between the touch panel and the polarizer, the magnetic field direction is as shown in fig. 8. That is, by directing the antenna coil toward the cover glass, the antenna radiates a magnetic field outward through the cover glass of the screen, achieving electromagnetic coupling. Because no object absorbing or isolating the magnetic field exists in the stack of the screen assembly, the functions of card simulation and card reader, P2P and other NFC functions can be realized.
Further, the display device further comprises a metal layer (not shown in the figure), and the metal layer is arranged on one surface of the back plate far away from the display panel. Preferably, the metal layer is a metal frame. By arranging a layer of metal frame below the back plate, the electromagnetic interference of the NFC antenna on other devices can be effectively avoided.
