Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, 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, not to limit the present invention.

[0042] In the present invention, the electrodes of the touch screen terminal are multiplexed to send and receive signals, and then the electric field is used as a communication medium to realize NFC communication. refer to figure 1 , there is a near electric field 3 between the touch screen terminal 1 and the touch screen terminal 2. In the present invention, both of them have the function of sending and receiving. When the touch screen terminal 1 sends information to the touch screen terminal 2, the applied communication medium is the electric field whose direction of the electric field points to ...

Abstract

A touch-screen terminal, method and system for near-field communication are provided. The touch-screen terminal includes a touch sensor, the touch sensor includes multiple driver electrodes and inductive electrodes disposed on a substrate to form capacitor structures. At least one of the driver electrodes and the inductive electrodes is used as a transmitting electrode; at least another one of the driver electrodes and the inductive electrodes is used as a receiving electrode. In the present invention, signal transmitting and receiving are achieved by multiplexing the electrodes of the touch-screen terminals, thereby enabling electric-field-based NFC. The system part for signal processing is embedded in the chip and, therefore, there is no need for an additional inductive card reader or part with the similar function. The present invention does not change the original size of the touch-screen terminal.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a near-field communication method and system for a touch screen terminal and a touch screen terminal. Background technique [0002] Near Field Communication (NFC) is a non-contact identification and interconnection technology that uses a 13.56MHz near-field magnetic field communication method to perform near-field communication between mobile devices, consumer electronics, PCs, and smart control tools. Wireless communication over a distance allows users to exchange information and access content and services simply and intuitively. [0003] The market demand for integrated NFC in mobile phones and other handheld devices has matured, and it can be used for mobile payment or even as a POS machine. However, the refitted handheld device has a large volume, and there are restrictions on the structural layout and component materials of handheld devices such as mobile phones. Co...
