Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0045] Near Field Communication technology (Near Field Communication, NFC) has the characteristics of short transmission distance, low energy consumption, and the signal is not easy to be interfered. It is suitable for application in smart payment and smart wearable devices. Or on the battery, the NFC antenna provided in this embodiment can be integrated on the display panel to improve product integration, realize thinner products, and make the NFC antenna closer to the surface of the display device for better comm...

Abstract

The invention discloses a near field communication antenna and a manufacturing method thereof, a display module and a display system, wherein the near field communication antenna comprises a substrate, wherein an annular antenna is arranged on the substrate; the annular antenna comprises a line-crossing area and an annular wire; the annular antenna further comprises a first electrode terminal anda second electrode terminal; the annular wire is connected with the first electrode terminal and the second electrode terminal, so that signals of the annular antenna can reach the second electrode terminal from the first electrode terminal; the annular wire comprises an M1 bottom layer structure and an M2 top layer structure, wherein the M1 bottom layer structure is arranged on the substrate, andthe M2 top layer structure is in contact with the bottom layer structure and is far away from the substrate; and the line-crossing area comprises an M1 bottom layer structure arranged on the substrate, an insulating layer in contact with the bottom layer structure, and an M2 top layer structure in contact with the insulating layer and far from the insulating layer. By virtue of the near field communication antenna and the manufacturing method thereof, the display module and the display system provided by the invention, the problem that the signal transmitting performance of an NFC antenna ofan existing display screen is relatively poor is solved.

Description

technical field [0001] The invention relates to the field of near-field technology, in particular to a near-field communication antenna, a manufacturing method thereof, a display module and a display system. Background technique [0002] Near Field Communication technology (Near Field Communication, NFC) is a non-contact identification and interconnection technology, which uses a near-field magnetic field communication method, has the characteristics of short transmission distance, low energy consumption, and the signal is not easily interfered. It can be used in mobile devices , consumer electronics products, and smart control tools for short-range wireless communication. [0003] At present, the display screens of many mobile terminals such as mobile phones are integrated with NFC functions, but the antennas of existing NFC products are mainly integrated on one side of the battery, or attached to the inner side of the casing, generally on the printed circuit board (Printed...
