Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a protective film management system used in a smart terminal and, more particularly, to a protective film management system used in a smart terminal, for managing a sales status of protective films by assigning serial numbers to the protective films and registering the serial numbers. 
       BACKGROUND ART 
       [0002]    Generally, smart terminals including a cellular phone, a smart pad, and a tablet PC are equipped with a display comprised of a liquid crystal display (LCD) panel, the display being exposed. 
         [0003]    Due to characteristics of the panel or according to use states by a user, the display is liable to become dirty or be smudged by fingerprints, ambient dust (e.g., greasy marks), or undesired shocks. 
         [0004]    To protect the display from an external environment and use the display in a pleasant state, users who use smart terminals including cellular phones attach protective films made of various types of transparent synthetic resins to displays of the smart terminals. The protective films have been sold at a high cost as functions thereof are improved but after service (A/S) therefor has been provided free of charge. 
         [0005]    However, in this case, since a seller of the protective films cannot verify whether a protective film used by a user is a protective film sold thereby and there are many reproduction films in the case of an expensive film, the seller should record a sales status in detail. 
         [0006]    In addition, if a sold protective film has defects, the seller needs to provide A/S free of charge and, if a buyer of a defective protective film requests exchange, the seller should exchange the protective film. Then, the seller checks sales status information listed in a sales process to verify whether the A/S requested protective film or the exchange requested protective film is a protective film sold thereby. However, this process is very inconvenient. 
       DETAILED DESCRIPTION OF THE INVENTION 
     Technical Problems 
       [0007]    The present invention has been made in view of the above problems, and it is an object of the present invention to provide a protective film management system used in a smart terminal, for managing a sales status of protective films by assigning serial numbers to the protective films and registering the serial numbers. 
         [0008]    It is another object of the present invention to provide a protective film management system used in a smart terminal, for preventing illegal reproduction of protective films by assigning serial numbers capable of uniquely identifying sold protective films. 
         [0009]    It is still another object of the present invention to provide a protective film management system used in a smart terminal, for installing a storage medium for providing information stored in a radio frequency identification (RFID) tag manner on one end surface of a protective film and transmitting the information stored in the storage medium to a protective film management server through a protective film management application by executing the protective film management application in the case in which the protective film approaches a screen of the smart terminal. 
         [0010]    It is a further object of the present invention to provide a protective film management system used in a smart terminal, for checking whether a protective film management application is installed in the smart terminal when a protective film including a storage medium for providing information stored in an RFID tag manner approaches a screen of the smart terminal and providing a screen for installing the protective film management application when the protective film management application is not installed. 
       TECHNICAL SOLUTIONS 
       [0011]    According to an aspect of the present invention, provided herein is a protective film management system including a protective film including identification (ID) information and an attachment guide indicator, and a protective film management server configured to provide a protective film management application to a smart terminal in response to an installation request signal of the protective film management application so that the smart terminal downloads and installs the protective film management application, to receive a result of matching the ID information of the protective film with ID information of the smart terminal through the protective film management application, and to generate and manage protective film sales information. 
         [0012]    The ID information of the protective film may be a serial number. 
         [0013]    The protective film management server may compare the ID information of the protective film with preregistered ID information of the protective film upon receiving the ID information assigned to the protective film from the smart terminal and may output a message indicating that the protective film is a reproduced film to the smart terminal when the same ID information is present, and the ID information of the protective film may be a serial number. 
         [0014]    The protective film may further include a quick response (QR) code for providing information capable of executing the protective film management application, and, if the QR code is read by the smart terminal, the smart terminal may execute the protective film management application to cause a user to input the ID information of the protective film when the protective film management application is installed in the smart terminal and online-access the protective film management server when the protective film management application is not installed in the smart terminal. 
         [0015]    The protective film may further include a storage medium configured to store the ID information of the protective film and installation information of the protective film management application and to transmit the stored ID information and installation information of the protective film management application according to a proximity communication scheme, and, if the protective film approaches the smart terminal, the smart terminal may receive the ID information and the installation information of the protective film management application from the storage medium, output an installation guide message of the protective film management application on a screen, receive the protective film management application from the protective film management server upon inputting the installation request signal of the protective film management application according to manipulation by a user, and install the protective film management application. 
         [0016]    The smart terminal may confirm whether the protective film is normally attached to the smart terminal in a screen setup state and transmit the ID information of the protective film to the protective film management server when the protective film has been attached to the smart terminal. 
         [0017]    If the attached protective film is removed from the smart terminal, the smart terminal may recognize removal of the protective film, generate protective film removal information, and transmit the protective film removal information to the protective film management server. 
         [0018]    The storage medium may be implemented as a sticker and may be attached to one side of a release paper of the protective film. 
         [0019]    The storage medium may be provided in a printed form at one side of an outer end of a main film of the protective film. 
         [0020]    If the ID information of the protective film to which the removal information is linked is received, the protective film management server may output an announcement message indicating that the protective film has been removed from the smart terminal on the screen of the smart terminal. 
         [0021]    If after service (A/S) is performed on a sold protective film, the protective film management server may cause A/S information to be input, receive a result of matching the ID information of the protective film  100  for which A/S is provided with the A/S information, and manage the A/S information. 
         [0022]    The protective film management server may transmit the A/S information to a protective film manufacturer server. 
       ADVANTAGEOUS EFFECTS 
       [0023]    According to the present invention, a protective film management system can manage a sales status of protective films by assigning serial numbers to protective films used in a smart terminal. Therefore, inconvenience caused by recording of sold protective films one by one by a seller n can be solved and efficiency of sales management can be maximized by automatically recording the serial numbers through linkage with information about the smart terminal. 
         [0024]    According to the present invention, the protective film management system assigns serial numbers capable of identifying sold protective films and, if the same serial number as an input serial number is present, outputs a message indicating an illegally reproduced protective film through a smart terminal, thereby preventing illegal reproduction of the protective films. 
         [0025]    According to the present invention, the protective film management system includes a storage medium for providing information stored in an RFID tag manner on one end surface of a protective film and transmits the information stored in the storage medium to a protective film management server through a protective film management application by executing the protective film management application in the case in which the protective film approaches a screen of a smart terminal, thereby automatically transmitting the information stored in the storage medium to the protective film management server without additional work by a seller or a buyer and managing protective films. 
         [0026]    According to the present invention, if a protective film including a storage medium for providing information stored in an RFID tag manner approaches a screen of a smart terminal, the protective film management system checks whether a protective film management application is installed in the smart terminal and, if the protective film management application is not installed, the protective film management system provides a screen for installing the protective film management application, thereby causing a seller or a buyer not to perform additional work for installing the protective film management application in the smart terminal and thus providing convenience.

         [0033]    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same or similar elements are denoted by the same reference numerals even though they are depicted in different drawings and a repetitive description thereof will be omitted. 
         [0034]    In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention. Further, it should be noted that the accompanying drawings are merely illustrated to easily explain the spirit of the invention and, therefore, should not be construed as limiting the spirit of the invention by the accompanying drawings. 
         [0035]      FIG. 1  is a diagram illustrating the construction of a protective film management system used in a smart terminal according to the present invention. 
         [0036]    As illustrated in  FIG. 1 , the protective film management system used in a smart terminal includes a protective film  100 , a smart terminal  200 , a protective film management server  300 , and a communication network  400  for providing a communication environment to transmit and receive data between the smart terminal  200  and the protective film management server  300 . 
         [0037]    The protective film  100  includes identification (ID) information and an attachment guide indicator. 
         [0038]    The smart terminal  200  includes a signal receiver  210  for receiving a signal transmitted by a proximity communication scheme, a storage unit  220  for storing an operation program and plural data, a controller  230  for controlling all constituent elements according to the operation program stored in the storage unit  220 , a communication unit  240  for transmitting a signal over the communication network  400  under control of the controller  230 , and an output unit  250  for outing various information on a screen under control of the controller  230 . The controller  230  of the smart terminal  200  transmits an access request signal to the protective film management server  300 , input by manipulation of an input unit (not shown) by a user, or an application installation request signal for managing the protective film, received from the signal receiver  210 , to the protective film management server  300  through the communication unit  240 . Next, the controller  230  of the smart terminal  200  downloads a protective film management application from the protective film management server  300  and installs the protective film management application. All of the above situations are output through the output unit  250  so that a user can confirm the situations. In this way, if the protective film management application is installed in the smart terminal  200 , when the user newly attaches a protective film to the smart terminal  200  or the user removes an old protective film and attaches a new protective film to the smart terminal  200 , the protective film ID information is manually or automatically matched with ID information of the smart terminal  200  and a matched result is transmitted to the protective film management server  300 . 
         [0039]    The protective film management server  300  allows the smart terminal  200  to download and install the protective film management application in response to the protective film management application installation request signal and generates and manages protective film sales information by receiving the result of matching the ID information of the protective film with the ID information of the smart terminal  200 . 
         [0040]    Upon receiving a serial number, which is the ID information assigned to the protective film  100 , from the smart terminal  200 , the protective film management server  300  compares the ID information assigned to the protective film  100  with preregistered ID information of the protective film  100  and, if the same ID information is present as a comparison result, the protective film management server  300  generates a message indicating that the protective film  100  is a reproduced protective film. Thus, both a protective film seller and a protective film buyer are easily aware of whether the protective film  100  which is sold or purchased is an original protective film or a reproduced protective film. Therefore, the protective film  100  can be prevented from being reproduced. 
         [0041]    The ID information of the protective film  100  is a serial number and may include manufacturer information, manufacture data information, and sales related information in addition to the serial number. In this case, the serial number may be provided by being printed on a release paper  101  constituting the protective film  100  (refer to  FIG. 2 ). 
         [0042]    The protective film  100  may further include a quick response (QR) code that provides information capable of executing the protective film management application. If the QR code is read through the smart terminal  200 , the smart terminal  200  executes the protective film management application to cause a user to input the ID information of the protective film when the protective film management application is installed in the smart terminal  200  and online-accesses the protective film management server  300  when the protective film management application is not installed in the smart terminal  200 . 
         [0043]    The protective film  100  further includes a storage medium  110  for storing the ID information and installation information of the protective film management application and transmitting the ID information and the installation information of the protective film management application according to a proximity communication scheme. If the protective film approaches the smart terminal  200 , the smart terminal  200  receives the ID information and the installation information of the protective film management application from the storage medium  110  and outputs an installation guide message of the protective film management application on a screen. If the installation request signal of the protective film management application is input by manipulation by a user, the smart terminal  200  receives the protective film management application from the protective film management server  300  and installs the protective film management application. 
         [0044]    The smart terminal  200  checks whether the protective film is normally attached thereto in a screen setup state and, if so, the smart terminal  200  transmits the protective film ID information to the protective film management server  300 . 
         [0045]    If the attached protective film  100  is removed from the smart terminal  200 , the smart terminal  200  recognizes this, generates protective film removal information, and transmits the protective film removal information to the protective film management server  300 . 
         [0046]    The storage medium  110  may be implemented as a sticker and may be provided by being attached to one side of the release paper  101  in the protective film  100  (refer to  FIG. 3 ). 
         [0047]    The storage medium  110  may be provided in a printed form at one side of an outer end of a main film  103  of the protective film (refer to  FIG. 4 . 
         [0048]    Upon receiving the protective film ID information to which the removal information is linked, the protective film management server  300  causes the smart terminal  200  to output an announcement message indicating that the protective film has been removed from the smart terminal  200  on a screen. 
         [0049]    If A/S for the sold protective film  100  is performed, the protective film management server  300  causes A/S information to be input, receives a result of matching the ID information of the protective film  100  for which A/S is provided with the A/S information, and manages the A/S information. 
         [0050]    The protective film management server  300  transmits the A/S information to a protective film manufacturer server  600 . 
         [0051]    A method of managing the protective film used in the smart terminal described above will be described in detail with reference to the attached drawings. 
         [0052]    &lt;Case in which protective film management application is not installed&gt; 
         [0053]    1. Manual Installation 
         [0054]      FIG. 3  is a flowchart illustrating a method of managing a protective film used in a smart terminal according to the present invention. 
         [0055]    A method of managing a protective film used in a smart terminal will now be described with reference to  FIG. 3 . The smart terminal  200  online-accesses the protective film management server  300  according to manipulation thereof by a user and downloads and then installs the protective film management application. 
         [0056]    If the protective film management application is executed according to manipulation of the smart terminal  200  by the user, the smart terminal  200  outputs a protective film ID information input request screen through the output unit  250 . 
         [0057]    If protective film ID information is input through the protective film ID information input request screen, the smart terminal  200  matches the protective film ID information with ID information of the smart terminal  200  and transmits a matched result to the protective film management server  300 . Then, the protective film management application outputs a protective film attachment guide indicator on the screen of the smart terminal  200 . The user attaches the protective film to the smart terminal  200  by matching an indicator indicated in the protective film with the indicator displayed on the screen. 
         [0058]    2. Automatic Installation 
         [0059]    If the protective film  100  including the storage medium  110  capable of transmitting information approaches the screen of the smart terminal  200  which has been turned on by a proximity wireless communication scheme according to manipulation by a user, the storage medium  110  and the signal receiver  210  of the smart terminal  200  perform communication so that the protective film ID information stored in the storage medium  110  and automatic installation information of the protective film management application are input to the controller  230  through the signal receiver  210  of the smart terminal  200 . 
         [0060]    Then, the controller  230  analyzes the automatic installation information of the protective film management application, online-accesses the protective film management server  300 , automatically downloads, installs, and executes the protective film management application, and transmits the protective film ID information to the protective film management server  300  through the protective film management application. 
         [0061]    &lt;Case in which protective film management application is installed&gt; 
         [0062]    1. Manual Input 
         [0063]    If the protective film management application is installed in the smart terminal  200  and a serial number is written in the protective film  100 , a user executes the protective film management application prior to attaching the protective film to the front surface of the smart terminal  200  and then inputs the serial number together with user information (information of the smart terminal). 
         [0064]      2 . Automatic Input 
         [0065]    If the protective film  100  including the storage medium  110  that transmits a signal by a proximity wireless scheme approaches the screen of the smart terminal  200  in which the protective film management application is installed, a protective film management application execution request signal and protective film ID information stored in the storage medium  110  are transmitted by a proximity wireless scheme and the signal receiver  210  of the smart terminal  200  receives the above signals and outputs the signals to the controller  230 . The controller  230  executes the protective film management application stored in the storage  220 , matches the protective film ID information with the ID information of the smart terminal through the protective film management application, and transmits the matched result to the protective film management server  300 . 
         [0066]    &lt;Protective film ID information management mode&gt; 
         [0067]    A protective film sales information management unit  330  of the protective film management server  300  receives the protective film ID information input from the smart terminal  200 , stores the protective film ID information in a protective film sales information database (DB)  310  as protective film sales information, and manages the protective film ID information. Upon receiving the protective film ID information from the smart terminal  200 , the protective film sales information management unit  330  determines whether the received protective film ID information has been registered in the protective film sales information DB  310 , and if the protective film ID information has been registered, provides a message indicating that a corresponding protective film is not a genuine product to be displayed on the screen of the smart terminal  200 . 
         [0068]    Meanwhile, if the protective film has a defect or problem, the user may request that a seller perform A/S. Then, the seller online-accesses the protective film management server  300  by manipulating a seller terminal device  500 , inputs the protective film ID information provided to user for A/S and A/S related information, and provides A/S for the protective film to the user. 
         [0069]    The protective film ID information and the A/S related information provided for A/S are stored in an A/S information DB  320  through a protective film A/S information management unit  340 . The protective film management server  300  statistically processes the protective film sales information and the A/S information registered in the protective film sales information DB  310  and the A/S information DB  320  and transmits the statistically processed data to a manufacturer server  600 , so that a manufacturer may use the data for manufacturing protective films and for marketing. 
         [0070]    Those skilled in the art will appreciate that the present invention may be carried out in other specific ways than those set forth herein without departing from the spirit and essential characteristics of the present invention. The above embodiments are therefore to be construed in all aspects as illustrative and not restrictive. The scope of the invention should be determined by the appended claims and their legal equivalents, not by the above description, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
