Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Cold light navigator fix information display card of the present invention comprises: multi-section cold light piece, RFID dual-mode antenna, cold light film driver module, signal processing chip, slimline battery, described cold light film driver module is used for output multi-channel drive singal, each drive singal output terminal connects a segment electrode of multi-section cold light piece respectively, and the public electrode of multi-section cold light piece connects the power supply output of cold light film driver module; Signal processing chip output terminal is connected with cold light film driver module, and RFID dual-mode antenna is connected with signal processing chip input end; Slimline battery is connected with cold light film driver module with signal processing chip; Signal processing chip receives the positional information from outside RFID transceiver and carries out respective handling, and the display information transmission after process is to cold light film driver module, and control the light on and off of multi-section cold light piece, namely multi-section cold light piece shows current positional information.
Described multi-section cold light piece forms multiple display segment, each display segment is corresponding with the RFID transceiver of external stability position, RFID dual-mode antenna in card receives the message of described RFID transceiver, and namely signal processing chip controls corresponding display segment and carry out display action.
In the present invention, the section of multi-section cold light piece can be rectangle, bar shaped, some shape and other any irregular figures that can mark information on map.The numbering message from different Transceiver Transmit that such RFID antenna receives, by with the recorded information comparison be stored in signal processing chip (being a MCU in figure), light corresponding cold light film thus obtain current positional information.As shown in Figure 1, having 16 in planimetric map can open/close cold light display segment, and the RFID transceiver of each display segment algorithmically with corresponding is corresponding.Whenever the RFID antenna of card Embedded receives the message of respective regions transceiver, namely MCU controls the display (as flicker etc.) that this display segment carries out respective algorithms;
As cold light driving chip, many employing MAX1452IE or SP4403EL.This two chip all has 4 output channels, and by the I of chip
2c port and external communication.Input voltage is about 3 ~ 5V, and such slimline battery just can reach and export requirement accordingly, as the CP042929 smart card battery etc. of GMBPOWER company.Because cold light display hop count is more in the present invention, so adopt HV3418 family chip, this is the low-pressure direct circulation high-voltage alternating chip of a employing HVCMOS technique, has 64 output channels, thus can drive 64 cold light display segments simultaneously.
For RFID receive-transmit system, adopt passive type ultrahigh frequency RFID, groundwork frequency range is at 860MHz ~ 960MHz, and operating distance >5 rice, cost is lower simultaneously.The RFID label tag of system have employed the UCODEG2iL family chip of NXP.
Fig. 3 illustrates the hierarchy of this information display card.From structure, release is divided into into five layers, is graph layer 1, transparent insulating layer 2, cold light lamella 3, RFID antenna layer 4, back-protective layer 5 from top to bottom respectively.Described graph layer 1 has printed the plane map of indicated indoor environment, and will need the part Vitrification management of display, material used is industrial PVC, and material is identical with described back-protective layer 5.Transparent insulating layer 2, cold light lamella 3 and RFID antenna layer 4 adopt PET film as substrate.For cold light lamella 3, the standard technology that multi-section cold light piece 6 structure adopts serigraphy to make according to cold light film is processed, bottom surface (PET film) adopts the upper copper wire of method deposition of metal deposition film simultaneously, and chip (cold light film driver module 8, signal processing chip 9) and slimline battery 7 are welded in cold light lamella PET film, as shown in Figure 4.RFID antenna layer 4 is deposited in RFID antenna layer PET film according to ad hoc structure by copper conductor, and be electrically connected by chip pin on through hole and cold light lamella 3.
Structurally, card sizes can carry out respective change according to indoor environment situation, but general reduction as possible on thickness.In the present embodiment, for cold light lamella, because needs carry out related circuit welding, so adopt thicker PET film (thickness is 90-120 μm), cold light film thickness is about 500 μm, and the thickness of slimline battery is about 500 μm.Chip thickness can be decreased within 600 μm after adopting nude film technique for sticking, if adopt the chip after encapsulation, thickness is about 2mm.But it is because chip present position is in card border side, little on the integral thickness impact of card.RFID antenna layer 4 adopts 25 μm of thick PET film, 10-15 μm of thick conductor layer.Thick about 25 μm of transparent insulating layer 2, graph layer and back-protective layer thickness are all about 50 μm.Such card integral thickness is 900 μm.Similar with common card thickness.Adopt the card heat pressing process of standard afterwards, by sandwich construction hot pressing together, thus make profile card as shown in Figure 2.
The present invention adopts electroluminescent cold-light lens as display device, and driven luminous by a special multichannel driver module, low in energy consumption, cost is low, effectively can substitute traditional display device.Electroluminescent cold-light lens is the main means of production with serigraphy simultaneously, and the mode of production is very flexible, can carry out corresponding by the image information of indoor, reach ideal application adaptability with mode of printing with RFID transceiver positional information.In addition electroluminescent cold-light lens can adopt the organic films such as PET as substrate, and the display apparatus module of making can appropriateness bend, thus can be integrated in curved face product.
