Description
Technical field
That the present invention relates to is a kind of near-field communication (Near Field Communication), refers to a kind of near-field communications system of the design with a plurality of antennas and relevant display device thereof especially.
Background technology
The near-field communication technology is to be used in in-plant wireless telecommunications; Among widespread usage has been lived at present; For example; The RF identification of noncontact (contact-less) induction type (Radio Frequency Identification is called for short RFID) card has been applied in the middle of the ticket and credit card trade of public transportation.The mode of near-field communication techniques make use induction coupling (inductive coupling) is carried out data transmission, is example with the rfid card or the RFID label (tag) of passive type (being non-transformer own), and rfid card and calculating punch inside all have coil antenna.Calculating punch produces AC magnetic field through its coil antenna, and the coil antenna of rfid card is then responded to this AC magnetic field to produce electric power, supplies the internal circuit running of rfid card required.Communication between rfid card and calculating punch is that the carrier wave through frequency spectrum medium-high frequency (HF is like 13.56MHz) or low frequency (LF is like 125KHz) partly carries out.Rfid card can be given calculating punch with the information-reply (backscatter) of its storage, and calculating punch also can transfer data to rfid card, so that data are write rfid card.Except the rfid card of calculating punch and passive type, near-field communication also can carry out through two transceivers (transceiver), and after the end transceiver transmission information, the transceiver of the other end is replied according to the good communication form of predefined.For example, promptly can the near-field communication technology between two mobile phones Data transmission mutually.
It is utilization near-field communication technology that kind of an application is arranged at present; Between computing machine and rfid card or mobile phone, carry out wireless telecommunications, the coil antenna that its near-field communication is used is wrapped in around the display panel, the user with rfid card or mobile phone near around be wound with the display panel of coil antenna; Rfid card or mobile phone can be coupled to radio-frequency module via antenna induction; To radio-frequency module, radio-frequency module reaches computing machine with described information again, and is presented on the display panel with transmission information.A kind of practical application mode is presented at Fig. 1 and Fig. 2, and it is respectively vertical view and side view.When two mobile phones 15,16 (or rfid card) during near touch-control display panel 11; The AC magnetic field (representing with the magnetic line of force among the figure) that radio-frequency module 13 is produced through antenna 12; Can respond to and be coupled to mobile phone 15,16; The user can operate touch-control display panel 11, with data transmission to the mobile phone 16 of instruct computer main frame 14 with mobile phone 15.So; Main frame 14 is after (handshaking) held in radio-frequency module 13 and mobile phone 15 completion friendships; Be about to the data that mobile phone 15 sees off and reach main frame 14 via radio-frequency module 13; Main frame 14 transfers to mobile phone 16 with data through radio-frequency module 13 after radio-frequency module 13 and mobile phone 16 completion friendships are held.
Yet; In above-mentioned application; Antenna 12 is wrapped in around the touch-control display panel 11, and when touch-control display panel 11 became big with ambient antenna 12, the area of mobile phone 15,16 (or rfid card) internal antenna and the area ratio of antenna 12 diminished relatively; 15,16 magnetic lines of force that can capture of mobile phone reduce relatively, thereby magnetic field intensity also diminishes.Carry out communication in order to let mobile phone 15,16 can capture enough magnetic field intensitys, radio-frequency module 13 must provide also big energy with antenna 12, as raising flow through antenna 12 electric current or increase the wire circle of antenna 12, with the also big magnetic field intensity of generation.Yet, so also can cause between electronic package and the near-field communication in the touch-control display panel 11 and disturb each other, and influence shows and the wireless telecommunications quality.On the other hand because the area of mobile phone 15,16 internal antennas diminishes with the area ratio of antenna 12 relatively, coupling be several (coupling coefficient) with diminish, also can influence communication quality.
In addition, in above-mentioned application,,, therefore be difficult to reach the efficient of multitask because main frame 14 only can be linked up through an antenna 12 and these mobile phones or rfid card if having a plurality of mobile phones or rfid card to carry out communication simultaneously via main frame 14.
