[0066] On the other hand, an embodiment also provides a method for manufacturing a touch sensor, which includes the following steps.

[0067]Coating conductive paste on the first surface of the substrate to form a first touch pattern layer, a first lead group and an antenna coil as an NFC antenna, the first lead group is electrically connected to the first touch pattern layer, and the antenna coil has a a first contact inside the coil and a second contact outside the coil;

[0068] Coating conductive paste on the second surface of the substrate to form a second touch pattern and a second lead group, the second lead group is electrically connected to the second touch pattern.

[0069] In one specific example, the preparation method further includes the following steps: forming a first insulating layer on the antenna coil, and then forming a first wire for connecting the first contact with the external chip.

Abstract

The invention discloses a touch substrate, a preparation method thereof, a touch module, a touch display screen and electronic equipment. The touch substrate comprises: a substrate, wherein a first touch pattern layer and a first lead group electrically connected with the first touch pattern layer are arranged on a first surface of the substrate; and an antenna coil which is arranged on the firstsurface, wherein the antenna coil comprises a coil part and a contact part, the coil part is arranged around the first touch pattern, the contact part comprises a first contact arranged in the coil part and a second contact arranged outside the coil part, and the first contact and the second contact are used for being electrically connected to an external chip; the substrate is further provided with a first through hole penetrating through the substrate, an electric conductor is arranged in the first through hole, the end, close to the first surface, of the electric conductor is electrically connected with the first contact, and the other end of the electric conductor extends to the second surface opposite to the first surface and forms a third contact on the second surface. According to the touch substrate, the integration process of the NFC antenna is simplified, and the risk that a traditional NFC antenna is artificially damaged is eliminated.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a touch sensor and a preparation method, a touch display screen, and electronic equipment. Background technique [0002] NFC (Near Field Communication, near-field communication technology) is a technology that enables devices to exchange data in close proximity, and is widely used in mobile terminals. By integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, mobile terminals can be used to realize functions such as mobile payment, electronic ticketing, access control, mobile identification, and anti-counterfeiting. [0003] The working frequency of the NFC antenna is 13.56MHz, and the radio frequency signal is transmitted by inductive coupling. In traditional technologies, the NFC antenna is usually an antenna coil printed on a film, and the NFC function is integrated into the electronic device by attach...
