Embodiment 1

[0031] Focusing on end-to-end communication and terminal-to-terminal interconnection, embodiments of the present invention provide a capacitive touch screen, which is a new type of touch screen proposed based on the working principle of a capacitive touch screen, such as figure 1 As shown, the capacitive touch screen of the present invention includes: a touch panel and a drive chip connected thereto, the touch panel includes a base layer and a protective layer covering the base layer; the drive chip includes a transmitting unit and receiving unit, where:

[0032] The base layer is based on the horizontal / vertical resolution of the touch screen, and N film conductors are arranged in the horizontal / vertical direction; figure 1 A schematic diagram of the thin film conductor structure laid out based on the horizontal resolution is shown in .

[0033] Wherein, the thin film conductor may be but not limited to ITO (Indium Tin Oxide) material.

[0034] The transmitting unit is used...

Embodiment 2

[0044] An embodiment of the present invention provides a terminal, and the touch screen of the terminal is the capacitive touch screen described in Embodiment 1. Wherein, when the capacitive touch screen is used for touch operation, the touch screen reports the touch position to the CPU of the terminal through the receiving unit, so as to realize the indication of the touch position.

[0045] Since the terminal described in this embodiment includes the capacitive touch screen described in Embodiment 1, the terminal has the technical effect described in Embodiment 1, which will not be repeated here.

Embodiment 3

[0047] An embodiment of the present invention provides a method for interconnection and communication between terminals, wherein the terminal is the terminal described in Embodiment 2, and the method is a device interconnection and end-to-end communication established based on the above-mentioned new capacitive touch screen. new methods such as figure 2 As shown, the method includes:

[0048] Step S201, enabling interconnection communication between the master and slave terminal devices;

[0049] In this step, starting the interconnection communication between the master and slave terminal devices includes: the master terminal device transmits the reference frequency to the slave terminal devices, and performs clock synchronization with the slave terminal devices and distinguishes tags.

[0050] Step S202, within a specified distance range, the slave terminal device receives in real time through its own receiving unit the frequency signal output by the high-frequency excitat...

Abstract

The present invention discloses a capacitive touch screen, a terminal and an inter-terminal interconnection communication method. The capacitive touch screen comprises a touch panel and a drive chip connected to the touch panel. With a horizontal / vertical resolution of the touch screen as a reference, N thin film conductors are arranged in the horizontal / vertical direction on the basal layer of the touch panel; a transmission unit of the drive chip is used for generating a high-frequency excitation signal and loading the high-frequency excitation signal onto each thin film conductor; and a receiving unit of the drive chip is used for receiving frequency signals output after the high-frequency excitation signal passes through all the thin film conductors one by one in a wireless reception manner, and determining a touch position according to changes of the frequency signals before and after touch. Compared with existing capacitive touch screen, the capacitive touch screen disclosed by the present invention has a low manufacturing cost and improves the existing drive chip, and the receiving unit is capable of receiving signals wirelessly, so that necessary technical support is provided for implementing terminal-to-terminal wireless communication among terminals.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a capacitive touch screen, a terminal and an interconnection communication method among the terminals. Background technique [0002] At present, one direction of the development of mobile phones and other terminal devices is to allow various devices to communicate with each other. Specifically, terminals such as mobile phones are relatively independent devices, and we need to find ways to make them work together better. We hope that terminals such as mobile phones can better interact with tablets or PCs (and future wearable devices) Or share content, and also want them to be able to communicate with other people's devices around them, share content or play games. [0003] How to achieve interconnection is a problem that all manufacturers are thinking about. The current technology is mainly focused on adding additional chips, adding transmitters and receivers, such as: Blue...
