Referring to FIG. 3B, although information in a particular form is being displayed, for example, an image is being displayed, on the entire display screen 195, in a state where the cover of the flip cover is open, such information may be displayed, for example, a part of an entire image may be displayed, in only an area of the display screen 195 which is exposed through each of the opening areas 310, 320, 330, 340a, 340b and 340c in FIGS. 4A to 4D, respectively.
Specifically, in a state where the cover of the flip cover is closed as illustrated in FIG. 3A, the user may identify information only through each of the opening areas 310, 320, 330, 340a, 340b and 340c in FIGS. 4A to 4D, respectively.
In various exemplary embodiments of the present invention, an area of the display screen 195, which is exposed through the opening area of the flip cover 300, is referred to as a display area matched to the opening area.
Meanwhile, various exemplary embodiments of the present invention relate to a method or an apparatus for displaying information in a partial area of the display screen 195, which is exposed through each of the opening areas as described above with reference to FIGS. 3A to 4D, which is seen through each of the opening areas, or which is transparently or translucently seen through transparent or translucent material in each of the opening areas. For example, in the exemplary embodiment of the present invention, when the cover of the flip cover 300 including the opening area is closed, as shown in FIG. 3A, it is necessary to identify which position is matched to an area, such as a display area exposed through the opening area, in the entire area of the display screen 195, what information is displayed in the display area, and the like. The identification of such positions and such information may be performed with reference to setting information of the display area, which is used and stored by the electronic device 100. Accordingly, setting information of each display area may include position data of each display area, type data related to each display area, order data related to the display areas, etc.
For example, according to the exemplary embodiment of the present invention, when the cover of the flip cover 300 including the opening areas enters a predetermined distance from the display unit 190, for example, within 5 mm., which is detected by the sensor module 170 shown in FIGS. 1 and 3B, or in the case of being closed as shown in FIG. 3A, the position data of the setting information may include data on a position, for example, a pixel position of each of display areas which are exposed through the opening areas in the entire area of the display screen 195, respectively. Also, when the cover of the flip cover 300 including the opening areas is closed, the type data of the setting information may include data on the type of information which is to be displayed in each display area. Lastly, when the flip cover 300 has the multiple opening areas and thus when there are a plurality of display areas matched to the multiple opening areas, the order data of the setting information may include data on the order of displaying the display areas.
The setting information of each display area may be acquired through an application market such as GOOGLE STORE, an online market commercially available from GOOGLE, INC., or may be acquired through downloading of the setting information of each display area which is shared by users. On the other hand, the user may manually set the setting information of each display area in steps S202 and S203 as described below.
Referring back to FIG. 2, if no setting information is detected in step 201, the controller 110 may determine in step 202 whether a request is made for setting the display area of the display screen 195 matched to the opening area of the flip cover 300. If no request is made, the method performs a corresponding or different function of the electronic device 100.
However, when a result of the determination in step 202 shows that the request is made for setting the display area of the display screen 195 matched to the opening area of the flip cover 300, the controller 110 may control the storage unit 175 so as to store a setting of the display area, which the user has set, as setting information in step 203, and the method loops back to step 201. In performing step 203, the electronic device 100 may also receive such setting information from a user using the input/output module 160, such as the buttons 161 or the keypad, and/or the display unit 190 having a touch screen to operate as an input device.
When the setting information of the display area of the display screen 195, matched to the opening area of the flip cover 300, is not identified or does not exist, the controller 110 may receive from the user the setting information of the display area, which the user has set using the input/output module 160 and/or the display unit 190 having a touch screen. For example, the setting information may include at least one of position data, type data, and order data.
The reception of settings and setting information, for example, position data of the setting information is described as follows. The user may manually input position data of the display area of the display screen 195 matched to the opening area of the flip cover 300.
Referring to FIG. 5, when the opening area 310 of the flip cover 300 has a rectangular shape, a display area on the display screen 195 which is matched to the opening area 310 also has a substantially rectangular shape which may be substantially identical in size and shape with the opening area 310. Accordingly, the user inputs pixel coordinate values (x1, y1), (x2, y2), (x3, y3) and (x4, y4) of vertices which form a rectangular display area on the display screen 195 in response to the position and shape of the opening area 310, and thereby may set position data of the display area matched to the opening area 310. For example, the controller 110 may determine that the display area matched to the opening area 310 is a rectangle formed by the vertices represented by (x1, y1), (x2, y2), (x3, y3) and (x4, y4) based on position data which is set by the pixel coordinate values (x1, y1), (x2, y2), (x3, y3) and (x4, y4), which the user has input through the input/output module 160 and/or the display unit 190 having a touch screen as the display screen 195.
In an alternative embodiment shown in FIG. 6 and different from the example as described with reference to FIG. 5, the user may directly draw the shape of a figure, matched to the opening area 310 of the flip cover 300, on the display screen 195 by using a touch input to a touch screen of the display screen 195 of the display unit 190, with the touch input represented by the shaded circle in the leftmost drawing in FIG. 6. Position data of the display area matched to the opening area 310 may be set from the shape of the figure which the user has drawn on the display screen 195.
Referring to FIG. 6, in a state where the flip cover 300 including an opening area 350a is closed, the user enters a touch input 360a or 360b (for example, draws a figure) matched to the shape of the opening area 350a, on a display screen 195 exposed through the opening area 350a. As a result, position data of a display area 350b matched to the opening area 350a may be set.
For example, the controller 110 may determine that the display area 350b matched to the opening area 350a has a display position and a shape, for example, a circle, based on the position data which has been set based on the touch input 360a or 360B. As shown in FIG. 6, the controller 110 may process the roughly drawn shapes from the touch inputs 360a, 360b, and create a more uniform or regular shape, such as a circle or square to be the final shape of the display area 350b, for example, using a library of shapes in the storage unit 175, or using shape recognition methods or shape creation methods known in the art.
Meanwhile, position data of setting information of the display area may be provided by the flip cover 300. For example, after position data, for example, pixel coordinate values, forming the display area of the display screen 195 matched to the opening area 350a of the flip cover 300 is stored in a tag 370 on the flip cover 300 shown in FIG. 3B, for example, a Radio Frequency Identification (RFID) tag or an NFC tag, corresponding to the short-range communication module 132, the flip cover 300 including the RFID tag or the NFC tag as the tag 370 in FIG. 3B, for example, the flip cover 300 to which the NFC tag is attached, may be provided. Then, when the electronic device 100 is combined with the flip cover 300, the controller 110 controls the short-range communication module 132 so as to be capable of acquiring (or identifying) position data of the display area matched to the opening area 350a of the flip cover 300 from the NFC tag of the flip cover 300.
At this time, not only the position data, but also data such as type data or order data may be simultaneously provided by the tag 370 corresponding to the short-range communication module 132 of the flip cover 300. For example, the entire setting information of the display area as described above may be stored in the tag 370 corresponding to the short-range communication module 132 of the flip cover 300. Accordingly, the setting of the display area may be automatically completed.
With respect to the setting information of the display area, a part of the reception of setting of type data is described as follows. The user may set what type of information (for example, output information of which application) is to be displayed in the display area of the display screen 195, which is exposed in a state where the flip cover 300 is closed.
Using the display areas of the display screen 195, which are visible through the opening areas in the flip cover 300, the display areas may operate in a first mode, for example, to always show specific information, such as the time and date through the opening areas and in the display areas whether or not the flip cover 300 is closed. The remaining display areas of the display screen 195, except for the display areas matching the opening areas, display information in a second mode, for example, web pages or other information on the display screen 195, with the second mode only operating when the flip cover 200 is open. In addition, in the second mode, the remaining portion of the display screen 195 may not display the specific which are only displayed in the display area matching the opening area.
FIG. 7 illustrates an example where time information (for example, an execution screen of a clock application or a clock widget) is set to be displayed in a display area 410a of the display screen 195 matched to an opening area 410b of the flip cover 300 when the flip cover 300 is closed, as in FIGS. 3A and 7. The clock application is visible in a first mode, in which the time information is visible to the user regardless of whether the flip cover 300 is open or closed. Other information on the display screen 195 is displayed in a second mode, in that the other information is displayed in the remaining portions of the display screen 195 only when the flip cover 300 is open, and such other information is not visible through the opening area 410b of FIG. 7 when the flip cover 300 is closed. In addition, in the second mode, the remaining portion of the display screen 195 may not display the time information which is only displayed in the display area 410a matching the opening area 410b. 
FIG. 8 illustrates an example where multiple types of information, which is to be displayed in a display area 420b of the display screen 195, matched to an opening area 420a of the flip cover 300, are set when the opening area 420a has a relatively large size. For example, the user may designate multiple applications, of information of each application is to be displayed in the display area 420b in a state where a cover of the flip cover 300 is closed, as shown in FIGS. 3A and 7. Accordingly, whether the flip cover 300 is open as in FIGS. 3B and 8, or closed as in FIGS. 3A and 7, such applications are visible in the first mode to the user directly on the whole display screen 195 as in FIGS. 3B and 8, or through the opening area 420a as in FIGS. 3A and 7.
Referring to FIG. 8, for example, when an SMS application 421, a KAKAOTALK application 422, which is a mobile messenger application commercially available from KAKAO INC., and a schedule application 423 are set as shown in FIG. 8, if the flip cover 300 is closed, the controller 110 may perform a control operation so as to display information (for example, a message or a notification message) of each of the SMS application 421, the KAKAOTALK application 422, and the schedule application 423 in the display area 420b. Accordingly, in the first mode, the applications 421-423 are visible whether or not the flip cover 300 is open or closed, while any applications or information on the remaining portions of the display screen 195 in FIG. 8, outside of the display area 420b, are only visible in the second mode, that is, when the flip cover 300 is open as shown in FIG. 8. In addition, in the second mode, the remaining portion of the display screen 195 may not display the applications 421-423 which are only displayed in the display area 420b matching the opening area 420a. 
With respect to setting information of the display area, a part of the reception of setting of order data is described as follows. When there are a plurality of opening areas 430a, 440a and 450a of the flip cover 300 in FIG. 9B, the order of display areas 430b, 440b, and 450b on the display screen 195 in FIG. 59A, in each of which information is to be displayed, may be designated. For example, the user may give the first position in the order to a display area 430b matched to an opening area 430a, may give the second position in the order to a display area 440b matched to an opening area 440a, and may give the third position in the order to a display area 450b matched to an opening area 450a. 
Referring back to FIG. 2, if setting information is detected in step 201, the controller 110 may determine whether the cover of the flip cover 300 has been closed in step 204. If not, the method loops back to step 201. Otherwise, when the controller 110 determines in step 204 that the cover of the flip cover 300 has been closed, the controller 110 may perform a control operation in step 205 so as to display previously-set information in the display area based on the setting information, and the method in FIG. 2 then ends.
In various exemplary embodiments of the present invention, the controller 110 may determine whether the cover of the flip cover 300 has been opened or closed, by using the sensor module 170, for example, by using an illuminance sensor or a Hall sensor. At this time, according to the exemplary embodiment of the present invention, when the sensor module 170 corresponds to a Hall sensor, a magnet matched to or in a complementary position relative to the Hall sensor must be mounted on the flip cover 300, such that the magnet and the Hall sensor in the sensor module 170 are in complementary positions when the flip cover 300 is closed. When the flip cover 300 is open the Hall sensor responds to a magnetic field level below a predetermined magnetic field strength threshold to determine that the magnet and, in turn, the flip cover 300 are distant from the Hall sensor, and so the flip cover 300 is open. However, when the flip cover 300 is closed, the Hall sensor responds to a magnetic field level above a predetermined magnetic field strength threshold to determine that the magnet and, in turn, the flip cover 300 are near the Hall sensor, and so the flip cover 300 is closed. Alternatively, the sensor module 170 may include an illuminance sensor which detects that the flip cover 300 is closed when a measured light level detected by the illuminance sensor is below a predetermined light threshold, and which detects that the flip cover 300 is open when a measured light level detected by the illuminance sensor is above a predetermined light threshold.
When the controller 110 determines that the cover of the flip cover 300 has been closed, the controller 110 identifies a position and a shape of the display area matched to the opening area of the flip cover 300, based on the setting information of the display area as described above. Then, the controller 110 performs a control operation so as to display previously-set information of the display screen 195 in display area, such that the position and shape of such information has been identified.
At this time, according to the type of information displayed in the display area or the user's setting, the information displayed in the display area may always be displayed or the information may be displayed at predetermined time intervals. Otherwise, only when an output event occurs, the display unit 190 may first be activated, and information may then be output in the display area on the display screen 195.
For example, when the type of information which is set to be displayed in the display area corresponds to time information, if the cover of the flip cover 300 is closed, time information may always be displayed in the display area or the time information may be displayed at predetermined time intervals therein. As another example, when the type of information which is set to be displayed in the display area corresponds to an SMS message, if an event of receiving a message occurs, the display unit 190 may first be activated, and the contents of the received message may then be scroll-displayed in the display area.
Referring to FIG. 10A, when the type of information which is to be displayed in a display area 460b of the display screen 195 matched to an opening area 460a of the flip cover 300 corresponds to an indicator bar and an SMS message, before the reception of the SMS message, the controller 110 may perform a control operation so as to display only information (for example, battery information, electric field information, and time information) in an indicator bar in the opening area 460a. Then, when the SMS message is received, the controller 110 may perform a control operation so as to scroll-display the information of the indicator bar and the received SMS message in the opening area 460a. 
In another example, shown in FIG. 10B, when the type of information, which is previously set to be displayed in a display area 470b on the display screen 195 matched to an opening area 470a through the identification of the setting information, corresponds to only an SMS message, only if the SMS message is received, the controller 110 activates the display unit 190, and controls the display unit 190 so as to display, on the display screen 195, the received SMS message in the display area 470b of the display screen 195.
In addition, a electronic device in the prior art causes red-colored, green-colored, or blue-colored LEDs to flicker on and off, and notifies the user of an event, for example, a voice call and the reception of a message, or an event required to charge a battery, generated by the electronic device in the prior art. The exemplary embodiment of the present invention may provide the function in the prior art of an event notification using LEDs or specific colors on the display screen 195 in the display area matched to the opening area of the flip cover 300. Accordingly, when the type of information displayed in the display area corresponds to a function of notification of an event occurrence, the exemplary embodiment of the present invention may display a graphic effect similar to flickering of LEDs on the display screen 195 in the display area.
For example, as illustrated in FIG. 11, a configuration for repeatedly displaying different colors at predetermined time intervals in a display area 480b, matched to an opening area 480a of the flip cover 300, may replace or supplement the function in the prior art of notification of an event occurrence using LEDs. As shown in FIG. 11, the differently shaded display areas 480b of the display screen 195 visible through the same opening area 480a, while the cover 300 is closed, provide the flickering graphic effect without using LEDs.

The programs and computer readable recording medium can also be distributed in network-coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
According to the various exemplary embodiments of the present invention, when a cover of a flip cover 300, a sliding cover, or a folder cover for protecting the electronic device 100 is located within a predetermined range of distance from the display screen 195 of the display unit 190 of the electronic device 100, for example, when the cover 300 is closed or is close to the display unit or display screen 195 by about 5 mm., a user can conveniently identify information even without opening the cover 300. Also, in a public place, the privacy of the user can be protected, and the user can observe the rules of etiquette, since the entire display screen 195 is not displayed, although other information such as the time may be visible through the opening areas. Therefore, the convenience of the user can be improved.
While the present invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and equivalents thereof.
