       [0014]    In order to make objects, technical details and advantages of the embodiments of the invention apparent, the technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the invention. Apparently, the described embodiments are just a part but not all of the embodiments of the invention. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the invention. 
       First Embodiment 
       [0015]    The first embodiment of the disclosure provides an electronic certificate. The electronic certificate can be a resident identification card, a passport, a visa, a student&#39;s identity card, a work card, a residential card, a graduation certificate, and any other kind of certification and documents to prove identity, experiences etc.  FIG. 1 a    is an exemplary main view of the electronic certificate, and  FIG. 1 b    is an exemplary side view of the electronic certificate. As is illustrated in  FIG. 1 a    in combination with  FIG. 1   b,  the electronic certificate  1  comprises an electronic certificate body  10 , a display screen  11  and an integrated circuit (IC)  12 . 
         [0016]    The display screen  11  is provided on a front side of the electronic certificate body  10 , to display item information of the electronic certificate  1 . When the display screen  11  is in a locked state, the display screen  11  does not display any item information. 
         [0017]    The IC  12  is connected with the display screen, to control a display function of the display screen  11 . 
         [0018]    Usually, the display screen  11  of the electronic certificate  1  is in the locked state, and it does not display any item information. Thus, anyone who is not a holder of the certificate will not obtain or even use any item information of the electronic certificate. When information related to the holder of the electronic certificate is required to be displayed, the electronic certificate receives verification information input by the holder of the electronic certificate, and then determines if the verification information is consistent with pre-stored information by the IC  12  which controls the display screen to display. If the verification information is consistent with the pre-stored information, the unlocked display screen  11  can display the item information of the electronic certificate. 
         [0019]    In the embodiment of the disclosure, the item information of the electronic certificate refers to information such as words, digits and images that can prove identity or experiences etc. of the holder of the electronic certificate. An example is illustrated below in which the electronic certificate is the identification card. The item information of the identification card comprises information, such as name, gender, nation, birthday, address where registered resident is, citizen identification number, photograph of the holder, etc. 
         [0020]    It should be noted that, a program or passport can be provided in the IC to prevent information from leakage, because the item information of the holder of the certificate and the preset verification information are stored in the IC of the embodiment of the disclosure. The program or the passport only can be operated or obtained by a specific department which issued the certificate, so that only the specific department can obtain or change the item information and the verification information in the IC. 
         [0021]    The first embodiment of the disclosure provides an electronic certificate. The electronic certificate comprises an electronic certificate body, a display screen and an IC. The display screen is provided on a front side of the electronic certificate body, to display item information of the electronic certificate, wherein the display screen does not display any item information, when the display screen is in a locked state; the IC is connected with the display screen, to control a display function of the display screen. The electronic certificate is provided with the display screen and the IC which controls the display screen to display, so the item information of the electronic certificate only can be displayed on the display screen by the holder of the electronic certificate, and cannot be displayed by anyone who is not the holder of the electronic certificate, so that the item information would not be used to engage illegal activities, to improve security of the electronic certificate. 
         [0022]    In an implementation of the embodiment of the disclosure, as illustrated in  FIG. 2 , the electronic certificate  1  further comprises a fingerprint recognition module  13  to recognize a fingerprint of the holder of the certificate. The fingerprint recognition module  13  is connected with the IC  12 . In this case, the IC  12  is further configured to determine whether fingerprint information input from the fingerprint recognition module  13  by the holder of the certificate is correct. 
         [0023]    Usually, the electronic certificate is in the locked state. When a finger of the holder of the certificate touches a region which can be recognized on the electronic certificate, fingerprint image information of the holder of the certificate is acquired by the fingerprint recognition module  13  and the acquired fingerprint image information is sent to the IC, so that the IC determines whether the fingerprint image information matches with pre-stored fingerprint information. The pre-stored information is stored in a storage module of the IC  12 . If the fingerprint image information does not match with the pre-stored fingerprint information, the IC  12  can display prompt information like “fingerprint is error” by the display screen to prompt the holder of the certificate to re-input. If the fingerprint image information matches with the pre-stored fingerprint information, the IC  12  can display prompt information like “fingerprint is correct” by the display screen to inform the holder of the certificate that the input fingerprint information is correct or unlock the display screen directly. 
         [0024]      FIG. 2  only illustrates that the fingerprint recognition module  13  is provided on lower right on the front side of the electronic certificate. However, it should be understood that, the fingerprint recognition module can be provided on any position on the electronic certificate, for example, on lower left on the front side of the electronic certificate, or on a position on the lateral side or back side of the electronic certificate, etc. The fingerprint recognition module  13  is provided on lower right on the front side of the electronic certificate, which may be more compliant with right-handed habit of human, that is, human often use his or her right hand to hold the electronic certificate, and the item information is usually arranged on positions on upper part and right part of the front side of the electronic certificate. Therefore, in some embodiments, the fingerprint recognition module can be provided on lower right on the front side of the electronic certificate. 
         [0025]    The fingerprint recognition module of the implementation of the disclosure can be an element, such as a scratch type fingerprint sensor and a press type fingerprint sensor. 
         [0026]    In another implementation of the embodiment of the disclosure, the electronic certificate  1  further comprises a face recognition module  14  to recognize a face of the holder of the certificate. The face recognition module  14  is connected with the IC  12 . In this case, the IC  12  is further configured to determine whether face information input from the face recognition module  14  by the holder of the certificate is correct. 
         [0027]    Usually, the electronic certificate is in the locked state. When a facial portion or face of the holder of the certificate is in a region which can be recognized on the electronic certificate, face image information of the holder of the certificate is acquired by the face recognition module  14  and the acquired face image information is sent to the IC  12 , so that the IC  12  determines whether the face image information matches with pre-stored face information. The pre-stored face information is stored in a storage module of the IC  12 . If the face image information does not match with the pre-stored face information, the IC  12  can display prompt information like “error” by the display screen to prompt the holder of the certificate to re-input. If the face image information matches with the pre-stored face information, the IC  12  can display prompt information like “correct” by the display screen to inform the holder of the certificate that the input face information is correct or unlock the display screen directly. 
         [0028]    The face recognition module  14  can be provided on a center of the front side of the electronic certificate, and can also be provided on other positions of the electronic certificate. For example, it can be provided on right part or left part of the front side of the electronic certificate where the face of the holder can be recognized. 
         [0029]    The face recognition module of the implementation of the disclosure can be an element, such as a micro-camera and an image sensor. 
         [0030]    It should be noted that, in addition to above mentioned fingerprint recognition module and face recognition module, the electronic certificate of the embodiment of the disclosure can comprise a voice recognition module which recognizes with audio frequency and tone color or an eye recognition module which acquires iris image with infrared. All of these recognition modules can improve security for the item information of the electronic certificate on the display to a great extent. 
         [0031]    In a third implementation of the embodiment of the disclosure, as illustrated in  FIG. 3 , the electronic certificate further comprises a passport unlock module  15  to recognize input from the holder of the certificate. The passport unlock module  15  is connected with the IC  12 . In this case, the IC  12  is further configured to determine whether passport information input from the passport unlock module  15  by the holder of the certificate is correct. 
         [0032]    The electronic certificate is usually in the locked state and the electronic certificate would not display item information thereof in the locked state. Thus, if the holder of the certificate wants to display item information of the electronic certificate, he or she can input unlock passport on a passport unlock region of the display screen  11  firstly, so that the passport unlock module  15  obtains the unlock passport information input by the holder of the certificate from the passport unlock region and sends the information to the IC  12 , in order that the IC  12  determines whether the information matches with pre-stored unlock passport information. The pre-stored unlock passport information is stored in the storage module of the IC  12 . 
         [0033]      FIG. 3  only illustrates a case that the passport unlock region is arranged in the center of the front side of the electronic certificate and a passport unlock manner is digit unlock. But in the disclosure, the position where the passport unlock region is arranged and the passport unlock manner are not limited to this, they can be other arrangement positions and unlock manners which are easily to occur to those skilled in related arts. For example, the passport unlock region is arranged on a back side of the electronic certificate, and the passport unlock manner is graph unlocking. 
         [0034]    It takes into account that, if the display screen is still enabled and displays the item information after the holder of the certificate turns on the display screen and completes to use the item information, it will not only consume a large quantity of power of the electronic certificate, but also increase risk to leakage the information. Therefore, in an implementation of the disclosure, as illustrated in  FIG. 4 , the electronic certificate  1  further comprises a switch  16  to turn on or off the display screen  11 , and the switch  16  is provided in the electronic certificate body  10 . 
         [0035]    For example, the electronic certificate  1  further can be provided with a switch  16  to turn on or off the display screen  11 . The switch can adopt button manner or push manner to switch on and switch off. When the switch  16  is switched on, the display screen is turned on, and the display screen turned on is in the locked state. When the switch  16  is switched off, the display screen is turned off in spite that the display screen  11  is in the locked state or in the unlocked state to display the item information. 
         [0036]    It can be seen from above, the switch  16  can control the display screen  11  to be turned on or off. When the item information needs not to be displayed, the display screen can be turned off by switching off the switch  16 . In this way, it can not only save electric quantity of the electronic, but also avoid the item information to be illegally used by anyone who is not the holder of the certificate. 
         [0037]    It should be noted that,  FIG. 4  only illustrates a case that the switch  16  is provided on a lateral side of the electronic certificate. In a practical application, the switch  16  also can be provided on other positions, for example, the back side of the electronic certificate. 
         [0038]    In an implementation of the disclosure, still refer to  FIG. 4 , the electronic certificate  1  further comprises a battery chamber  17 . The battery chamber  17  is provided in the electronic certificate body  10 , and a battery mounted in the battery chamber  17  can supply power to the display screen  11  and the IC  12 . 
         [0039]    It can be understood that, the battery of the embodiment of the disclosure is preferably thin and small, and the battery which uses the battery chamber is preferably light and small. In this way, it facilitates the holder of the certificate to carry the electronic certificate with the battery chamber. 
         [0040]    In an implementation of the disclosure, the display screen  11  is an OLED (Organic Light-Emitting Diode) display screen. 
         [0041]    The display screen which adopt material of OLED has advantages of self luminescence, no back light source, thin thickness, wide view angle, fast reaction rate, wide usage temperature rang etc.
