Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Cold light navigator fix information display card of the present invention comprises: multistage cold light film, RFID dual-mode antenna, cold light film driver module, signal processing chip, slimline battery; Said cold light film driver module is used to export multi-channel drive signal; Each drive signal output terminal connects a segment electrode of multistage cold light film respectively, and the public electrode of multistage cold light film connects the power supply output of cold light film driver module; The signal processing chip output terminal links to each other with the cold light film driver module, and the RFID dual-mode antenna links to each other with the signal processing chip input end; Slimline battery links to each other with the cold light film driver module with signal processing chip; Signal processing chip receives from the positional information of external RF ID transceiver and carries out handled, and the display message after the processing is transferred to the cold light film driver module, the light on and off of control multistage cold light film, and the multistage cold light film promptly shows current position information.
Said multistage cold light film constitutes a plurality of display segments; Each display segment is corresponding with the RFID transceiver of external stability position; RFID dual-mode antenna in card is received the message of said RFID transceiver, and signal processing chip is promptly controlled corresponding display segment and carried out display action.
Among the present invention the section of multistage cold light film can be that rectangle, bar shaped, some shape and other are any can the mark map on the irregular figure of information.The numbering message received of RFID antenna like this from the emission of different transceivers, through with the recorded information comparison that is stored in the signal processing chip (being a MCU among the figure), obtain current position information thereby light corresponding cold light film.As shown in Figure 1, having 16 in the planimetric map can open/close cold light display segment, and each display segment is corresponding with corresponding RFID transceiver on algorithm.Integrated RFID antenna is received the message of respective regions transceiver in card, and MCU promptly controls the demonstration that this display segment carries out respective algorithms (like flicker etc.);
As the cold light chip for driving, adopt MAX1452IE or SP4403EL more.This two chip all has 4 output channels, and the I through chip 2C port and external communication.Input voltage is about 3~5V, and slimline battery just can reach corresponding output requirement like this, like CP042929 smart card battery of GMBPOWER company etc.Because of cold light shows that hop count is more, so adopt the HV3418 family chip, this is the low-voltage direct commentaries on classics high-voltage alternating chip of a employing HVCMOS technology, has 64 output channels, thereby can drive 64 cold light display segments simultaneously among the present invention.
For the RFID receive-transmit system, adopt the passive type ultrahigh frequency RFID, the groundwork frequency range is at 860MHz~960MHz, operating distance>5 meters, cost is lower simultaneously.The RFID label of system has adopted the UCODEG2iL family chip of NXP.
Fig. 3 has showed the hierarchy of this information display card.On structure, release is divided into into five layers, is respectively graph layer 1, transparent insulating layer 2, cold light lamella 3, RFID antenna stack 4, back-protective layer 5 from top to bottom.Printed the plane map of indicated indoor environment on the said graph layer 1, and the part transparence that will show handles, used material is industrial PVC, and material is identical with said back-protective layer 5.Transparent insulating layer 2, cold light lamella 3 and RFID antenna stack 4 adopt the PET film as substrate.For cold light lamella 3; The standard technology that multistage cold light film 6 structures adopt serigraphy to make according to cold light film is processed; Bottom surface (PET film) adopts the method deposition of metal deposited film to go up the copper lead simultaneously; And chip (cold light film driver module 8, signal processing chip 9) and slimline battery 7 be welded on the cold light lamella PET film, as shown in Figure 4.RFID antenna stack 4 is that copper conductor is deposited on the RFID antenna stack PET film according to ad hoc structure, and is electrically connected through chip pin on through hole and the cold light lamella 3.
Structurally, card sizes can be carried out respective change according to the indoor environment situation, yet generally reduces as possible on the thickness.In the present embodiment, for the cold light lamella, owing to need carry out the related circuit welding, so adopt thicker PET film (thickness is 90-120 μ m), the cold light film thickness is about 500 μ m, and the thickness of slimline battery is about 500 μ m.Chip thickness can be decreased in the 600 μ m after adopting the nude film technique for sticking, if adopt the chip after the encapsulation, the about 2mm of thickness.But because the chip present position is little to the integral thickness influence of card in the card border side.RFID antenna stack 4 adopts the thick PET film of 25 μ m, the thick conductor layer of 10-15 μ m.Transparent insulating layer 2 thick about 25 μ m, graph layer and back-protective layer thickness all are about 50 μ m.The card integral thickness is 900 μ m like this.Similar with common card thickness.Adopt the card heat pressing process of standard afterwards, with sandwich construction hot pressing together, thereby process profile card as shown in Figure 2.
The present invention adopts the electroluminescence cold light film as display device, and through the multichannel driver module driven for emitting lights of a special use, low in energy consumption, cost is low, can effectively substitute traditional display device.Simultaneously the electroluminescence cold light film is the main means of production with serigraphy, and the mode of production is very flexible, can indoor image information be carried out correspondingly with mode of printing and RFID transceiver positional information, reaches very desirable application adaptability.Electroluminescence cold light film in addition can adopt organic film such as PET as substrate, and the display apparatus module of making is can appropriateness crooked, thereby can be integrated in the curved face product.
