Description
Technical field
The present invention relates to the smart card and its work of a kind of changeable colour smart card, more particularly to a kind of integrated electrochromic devices
Make method.
Background technology
Smart card is using chip as safety storage and using medium, and encapsulation is with microprocessor, safe processor in card
With the safety chip of memory, thus computing capability is high, and security protection ability is strong, and memory capacity is big.Key, numeral card can be stored
Book etc. needs information to be protected, a variety of application software of safe operation.Compared to technologies such as magnetic stripe card, ID cards, can store safely more
More consumer records and user profile, performance greatly improve, moreover it is possible to provide more value-added services, be widely used in finance, electricity
The fields such as letter, traffic, safety management and identification.But before and after 1998, Historic Evolution is longer for smart card invention, world mark
Be not defined its display function in standard, user can not understand whenever and wherever possible remaining sum in card inside information, including card, residue degree,
Whether the term of validity remains within bottom line etc..
The smart card of main flow does not have display function at present, and user must can just look into by equipment such as POS, ATM, mobile phones
Read card inside information, it is impossible to facilitate consult whenever and wherever possible.Some companies are it is also proposed that the scheme such as " visible card ", " bluetooth card " solves nothing
Method checks the problem of card inside information whenever and wherever possible, but due to the limitation of low-power consumption, small size, highly integrated technology and manufacturing process,
The Display Techniques such as Electronic Paper, liquid crystal micro screen can not popularization and application well.The thickness of actual finished product, anti-twist, anti-electromagnetism
Interference etc. can not also fully meet the related domestic or international standard of smart card, and the integrated cost of its finished product is too high, durable
Property is poor, and quality and security can not ensure well, can not substitute the smart card of main flow on a large scale.
The content of the invention
In view of the above-mentioned problems, the main object of the present invention is to provide a kind of changeable colour smart card.
It is a further object to provide a kind of smart card of integrated electrochromic devices and its method of work.
In order to realize above-mentioned main purpose, the smart card and its work of a kind of integrated electrochromic devices of the present invention
Make method, the simple small size electrochromic device of integrated morphology passes through smart card color into traditional intelligent card chip
Change, issue the user with simple prompting message（Such as Sorry, your ticket has not enough value）, low cost solves smart card information and can not look at any time
The problem read.
Relative to prior art, the beneficial effects of the present invention are：
The display module that the present invention uses is electrochromic device, and main control chip I/O pin controls the electrode of electrochromic device,
Change the color of off-color material.Design meets the associated international standards of smart card, simple in construction, using intelligent card chip pin outside
Add electrochromic device.User can obtain Igor Kanygin volume at any time according to the change of integrated electrochromic devices smart card color
The prompting message such as service condition, reduce production and design cost, it is practical.
Brief description of the drawings
Fig. 1 is the fundamental diagram of the present invention；
Fig. 2 is the electrochromic device structure chart of the present invention；
Fig. 3 is the workflow diagram of the present invention.
Embodiment
In order that goal of the invention, technical scheme and its advantage of the present invention become apparent from, below in conjunction with accompanying drawing and reality
Example is applied to be described in further detail the present invention.
This programme design includes main control chip（101）, chip pin（102）, antenna（103）And electrochromic device
（104）.Wherein, main control chip（101）With chip pin（102）It is connected, realizes that the way of contact operates；With antenna（103）Phase
Even, realize that cordless operates.Pass through one or more chip pins（102）, with one or more electrochromic materials
（104）It is connected, realizes the smart card of changeable colour.Fig. 1 show the operation principle of the present invention.
Fig. 2 show the structural principle of electrochromic device：Driving power（6）Trigger electrode（1）, electrode（4）Produce electricity
Lotus, so that electrochromic layer（3）Color changes.And in the case where losing power supply, color remains able to preserve.This
Invention controls voltage, electric current of respective pins etc. by main control chip, and then change using the physical characteristic of electrochromic device
The color of electrochromic device, the information of display user's concern.
Electrochromism refers to the optical property of material, such as color, light transmittance, reflectivity, is issued in DC Electric Field
The raw stable, phenomenon of reversible change.Material with electrochromic property is referred to as electrochromic material, is made with electrochromic material
It is referred to as electrochromic display device (ECD) for the display device of functional material.
Electrochromic material has a bistable function, after the color of material changes, even if removing extra electric field, material
The color of material can also continue to keep constant so that electrochromic display device (ECD) has the performance of super low-power consumption.With new material skill
The development of art, the species of electrochromic material are on the increase so that the side such as the color category of electrochromic display device, contrast
There is bigger selection space at the beginning of all relatively intelligent card inventions of face.
Fig. 3 show a kind of smart card of integrated electrochromic devices of the present invention and its workflow of method of work
Journey.
Step 1：When main control chip receives antenna or contacts the information sent contact（Such as increase more than remaining sum or reduction
The information such as volume）；
Step 2：Main control chip immediately treats information；
Step 3：Main control chip sends the corresponding signal such as voltage or electric current by pin, changes the color of off-color material.Example
When being higher than setting value such as remaining sum, electrochromic device 1 is green；When less than setting value, electrochromic device 2 is red, square
Just user obtains the information in card.
General principle, principal character and its advantage of the present invention has been shown and described above.Certainly, above-described embodiment is only
The preferred embodiment of the present invention.It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, it is above-mentioned
Merely illustrating the principles of the invention described in embodiment and specification, without departing from the spirit and scope of the present invention,
