         [0045]      FIG. 1  is a block diagram illustrating an example of a display apparatus  100  included in a display apparatus system according to an embodiment. 
         [0046]    Referring to  FIG. 1 , the display apparatus  100  included in a display apparatus system may include a display unit  10 , a scan driver  20 , a data driver  30 , a controller  40  and a power supply  50 . 
         [0047]    The display apparatus  100  included in a display apparatus system according to an embodiment may include one or more of various apparatuses such as a liquid crystal display apparatus, a thin film transistor-liquid crystal display apparatus, an organic light emitting display apparatus, a three-dimensional display apparatus, and an electrophoretic display apparatus. In embodiments, at least a portion of the display apparatus  100  included in the display apparatus system according to an embodiment may include a flexible display apparatus. Especially, at least a portion of the display apparatus  100  included in the display apparatus system according to an embodiment may include a bendable display apparatus or a stretchable display apparatus. A case in which the display apparatus  100  is an organic light emitting display apparatus will be described as an example below. In embodiments, the display apparatus  100  may be a bendable display apparatus and/or a stretchable display apparatus. 
         [0048]    The display unit  10  may include a plurality of pixels PX arranged in a matrix form. Each pixel PX may be connected to a corresponding scan line among scan lines SL 1  through SLm and to a corresponding data line among data lines DL 1  through DLn, and a control signal and a data voltage may be provided thereto. Each of the scan lines SL 1  through SLm may transmit a control signal outputted from the scan driver  20  to pixels PX on an identical row, and each of the data lines DL 1  through DLn may transmit a data voltage outputted from the data driver  30  to pixels PX on an identical column. Each of the scan lines SL 1  through SLm is illustrated as one line in  FIG. 1 ; however, some pixels PX may include a plurality of lines to transmit a plurality of control signals in parallel. 
         [0049]    Pixels PX may receive a first driving voltage ELVDD and a second driving voltage ELVSS. The first driving voltage ELVDD and the second driving voltage ELVSS are driving voltages for an organic light emitting diode of a pixel to emit light, and the first driving voltage ELVDD may have a higher voltage level than the second driving voltage ELVSS. The pixel PX may control the amount of electric current flowing from the first driving voltage ELVDD via the organic light emitting diode to the second driving voltage ELVSS, based on the data voltage transmitted via a corresponding data line. The data voltage may denote a signal transmitted via a corresponding data line or its voltage level. The pixel PX may include a light emitting element emitting light with luminance corresponding to the data voltage or may transmit the amount of light corresponding to the data voltage. The pixel PX may denote a sub-pixel which is a portion of the pixel PX capable of displaying full colors, or may denote a set of sub-pixels, which is a reference for representing resolution, or may denote the pixel PX itself outputting or transmitting a single color (for example, white color). The pixel PX may include a color filter depending on an operation method of the display apparatus  100 . 
         [0050]    The controller  40  may receive a vertical synchronizing signal Vsync, a horizontal synchronizing signal Hsync, a data enable signal DE, a clock signal CLK, and a data signal RGB from the outside. The controller  40  may control an operation timing of the scan driver  20  and the data driver  30  via timing signals such as the vertical synchronizing signal Vsync, the horizontal synchronizing signal Hsync, the data enable signal DE, and the clock signal CLK. Since the controller  40  may determine a frame period via counting the data enable signal DE during one horizontal scanning period, the vertical synchronizing signal Vsync and the horizontal synchronizing signal Hsync supplied from the outside may be omitted. The data signal RGB may include luminance information of pixels PX. The luminance may have gray levels of certain numbers, for example, 1024, 256, or 64. 
         [0051]    The controller  40  may generate control signals including a gate timing control signal GDC to control the operation timing of the scan driver  20  and a data timing control signal DDC to control the operation timing of the data driver  30 . 
         [0052]    The gate timing control signal GDC may include a gate start pulse GSP, a gate shift clock GSC, a gate output enable GOE, etc. The gate start pulse GSP may be supplied to the scan driver  20  in which a first scan signal is generated. The gate shift clock GSC may be a clock signal inputted in common to the scan driver  20  and may be the clock signal CLK to shift the gate start pulse GSP. The gate output enable GOE signal may control an output of the scan driver  20 . 
         [0053]    The data timing control signal DDC may include a source start pulse SSP, a source sampling clock SSC, a source output enable SOE signal, etc. The source start pulse SSP may be a signal to control a starting time of data sampling of the data driver  30 . The source sampling clock SSC may be the clock signal CLK to control a data sampling operation of the data driver  30  based on a rising edge voltage, a falling edge voltage, or a certain flat voltage. The source output enable SOE may be a signal to control an output of the data driver  30 . The source start pulse SSP supplied to the data driver  30  may be omitted depending on a data transfer method. 
         [0054]    The scan driver  20  may sequentially generate control signals to operate pixels PX included in the display unit  10 , in response to the gate timing control signal GDC supplied from the controller  40 . The scan driver  20  may supply control signals to pixels PX included in the display unit  10  via the scan lines SL 1  through SLm. A plurality of control signals may be provided to one pixel PX depending on a design of the pixel PX. For example, first through third control signals or more control signals may be provided to one pixel PX during one frame according to a certain sequence. 
         [0055]    The data driver  30  may sample the data signal RGB supplied from the controller  40  in a digital type and latch and change the data signal RGB to data in a parallel data system, in response to the data timing control signal DDC supplied from the controller  40 . When the data driver  30  changes the data signal RGB in the digital type to data in the parallel data system, depending on the driving method of the display apparatus  100 , the data signal RGB in the digital type may be changed to a gamma-based voltage and to a data voltage in an analog type. The data driver  30  may supply the data voltage to pixels PX included in the display unit  10  via the data lines DL 1  through DLn. 
         [0056]      FIGS. 2A through 2C  are diagrams illustrating movements of display apparatuses of a display apparatus system according to embodiments.

Each of the first and second display apparatuses  100   a  and  100   b  may be the display apparatus  100  described with reference to  FIG. 1 . Alternatively, each of the first and second display apparatuses  100   a  and  100   b  may each be the display unit  10  sharing together some composing elements of the display unit  100  described with reference to  FIG. 1 . A case in which each of the first and second display apparatuses  100   a  and  100   b  is the display apparatus  100  will be described as an example below. 
         [0058]    The first and second display apparatuses  100   a  and  100   b  may be arranged adjacent to each other by a space R with a certain distance. In detail, the first and second display apparatuses  100   a  and  100   b  may be arranged such that a first edge El at a bottom portion of the first display apparatus  100   a  faces a second edge E 2  at a top portion of the second display apparatus  100   b;  in this case, a range between the first edge E 1  and the second edge E 2  may be the space R. In embodiments, a distance between the first edge E 1  and the second edge E 2  may be a first distance L 1 . The first and second display apparatuses  100   a  and  100   b  may be respectively attached to a wall and to a surface of a drawer, which is automatically or manually movable. The first and second display apparatuses  100   a  and  100   b  may be flat display apparatuses that attach to a flat surface or curved display apparatuses that attach to a curved surface. 
         [0059]    In this case, at least one image-display surface (e.g., display area or display range) of at least one of the first and second display apparatuses  100   a  and  100   b  may be extended and fill the space R between the first and second display apparatuses  100   a  and  100   b.  In detail, in the case of  FIG. 2A , a range in which image-display surfaces (e.g., display areas) of the first and second display apparatuses  100   a  and  100   b  exist may be the display range where an image is displayed, and the space R between the first and second display apparatuses  100   a  and  100   b  may be a range in which an image may not be displayed. When at least one of the first and second display apparatuses  100   a  and  100   b  is extended to the space R, the range which has been the space R may be changed to the display range. In other words, at least one of the first and second display apparatuses  100   a  and  100   b  may be extended and the display range may be arranged in the space R. 
         [0060]    Referring to  FIG. 2B , only one of the first and second display apparatuses  100   a  and  100   b  may be extended and the display range may be arranged in the space R. For example, the second display apparatus  100   b  may be extended in a direction of the second edge E 2  toward a location in which the first display apparatus  100   b  is arranged. In this case, the second display apparatus  100   b  may be extended until the second edge E 2  moves by the first distance L 1  and contacts the first edge E 1 , or the second display apparatus  100   b  may be extended until the second edge E 2  moves a distance less than the first distance L 1  and thus, the distance between the first and second edges E 1  and E 2  becomes less than that prior to an extension of the second display apparatus  100   b . In this case, a result that the display range is arranged in the space R also may occur via an arrangement of the second display apparatus  100   b  in the space R. 
         [0061]    Alternatively, referring to  FIG. 2C , both of the first and second display apparatuses  100   a  and  100   b  may be extended and the display range may be arranged in the space R. For example, the first display apparatus  100   a  may be extended in a direction of the first edge E 1  toward a location in which the second display apparatus  100   b  is arranged, and the second display apparatus  100   b  may be extended in a direction of the second edge E 2  toward a location in which the first display apparatus  100   a  is arranged. In this case, both of the first and second edges E 1  and E 2  may move to a range which has been the space R. The first and second display apparatuses  100   a  and  100   b  may be extended until the first and second edges E 1  and E 2  are in contact with each other, or until the distance between the first and second edges E 1  and E 2  becomes less than that prior to the extension of the first and second display apparatuses  100   a  and  100   b.  When at least one of the first and second display apparatuses  100   a  and  100   b  is extended, the first and second display apparatuses  100   a  and  100   b  may display one image. In other words, a portion of an image may be displayed on the first display apparatus  100   a  and the other portion of the image may be displayed on the second display apparatus  100   b.  When there is the space R between the first and second display apparatuses  100   a  and  100   b,  an improper display of one image, such as a portion of one image being not displayed or being disconnected, may occur; however, when the display range of at least one of the first and second display apparatuses  100   a  and  100   b  is extended, the image may be properly displayed. A method of extending at least one of the first and second display apparatuses  100   a  and  100   b  will be described in detail with reference to  FIGS. 4A, 4B, 5A, and 5B  below. 
         [0062]    In embodiments, the first and second display apparatuses  100   a  and  100   b  are illustrated as rectangles of a same size in  FIG. 2A ; however, it is exemplary only, and the first and second display apparatuses  100   a  and  100   b  may have different sizes and may be display apparatuses having various kinds of geometrical shapes such as a polygon, a circle, and an ellipse. The first and second display apparatuses  100   a  and  100   b  will be described with reference to  FIGS. 3A and 3B . 
         [0063]      FIGS. 3A and 3B  are diagrams illustrating arrangements of display apparatuses of a display apparatus system according to embodiments. 
         [0064]    Referring to  FIG. 3A , the first and second display apparatuses  100   a  and  100   b  may be arranged so that a bottom edge of the first display apparatus  100   a  and a top edge of the second display apparatus  100   b  face each other. The bottom edge of the first display apparatus  100   a  and the top edge of the second display apparatus  100   b  may have a curve shape. In this case, the space R may be a range existing between the first and second display apparatuses  100   a  and  100   b  and may be the range having a geometrical shape including all curved and linear edges. At least one of the first and second display apparatuses  100   a  and  100   b  may change the shape so that the first display apparatus  100   a  is extended in a direction of the bottom edge or the second display apparatus  100   b  is extended in a direction of the top edge and thus, the display range is arranged in the space R. 
         [0065]    Alternatively, referring to  FIG. 3B , the first display apparatus  100   a,  in a shape of surrounding the second display apparatus  100   b,  may be arranged in a rectangular loop-shape on the outskirts of the second display apparatus  100   b.  In this case, the space R maybe a range with the rectangular loop-shape existing between the first and second display apparatuses  100   a  and  100   b.  At least one of the first and second display apparatuses  100   a  and  100   b  may change the shape so that the first display apparatus  100   a  is extended in respective direction of inner edges or the second display apparatus  100   b  is extended in respective direction of outer edges and thus, the display range is arranged in the space R. 
         [0066]    As described above, the first and second display apparatuses  100   a  and  100   b  included in the display apparatus system according to the present inventive concept may be display apparatuses having various shapes and may be arranged in various geometrical relationships. 
         [0067]      FIGS. 4A and 4B  are diagrams illustrating methods of arranging a display range in a space between display apparatuses of a display apparatus system according to embodiments. 
         [0068]    Referring to  FIG. 4A , a display apparatus system may include a first display apparatus  100   a  and a second display apparatus  100   b.  In this case, at least one of the first and second display apparatuses  100   a  and  100   b  may be a bendable display apparatus. For example, the second display apparatus  100   b  may be a bendable display apparatus. In this case, a second edge E 2  of the second display apparatus  100   b  may be an inside edge in a display range of the second display apparatus  100   b  and may be a location in which the second display apparatus  100   b  may be bent. In other words, when the second display apparatus  100   b  is bent, the second edge E 2  is revealed as an edge, and when the second display apparatus  100   b  is changed to an un-bent shape, the second edge E 2  may be changed into the inside range of the display range of the second display apparatus  100   b.    
         [0069]    In this case, referring to  FIG. 4B , a degree of bending of the second edge E 2  of the second display apparatus  100   b  may be changed. In detail, the second edge E 2  may be changed to an un-bent state or a less-bent-than-before-the-change state. In this case, the display range which is a bent top portion of the second edge E 2  of the second display apparatus  100   b  may move from the bent state of the second display apparatus  100   b  to a range which has been a space between the first display apparatus  100   a  and the second display apparatus  100   b.  As a result, the second display apparatus  100   b  may be extended and an effect may occur that the display range may be arranged in the space between the first display apparatus  100   a  and the second display apparatus  100   b.    
         [0070]    A case in which only the second display apparatus  100   b  is a bendable display apparatus is described as an example in  FIGS. 4A and 4B ; however, the present inventive concept is not limited thereto and both of the first and second display apparatuses  100   a  and  100   b  may be bendable display apparatuses. In this case, the first edge E 1  of the first display apparatus  100   a  may be an inside edge in the display range and may be a location in which the first display apparatus  100   a  may be bent. 
         [0071]      FIGS. 5A and 5B  are diagrams illustrating another method of arranging a display range in a space between display apparatuses of a display apparatus system according to embodiments. 
         [0072]    Referring to  FIG. 5A , a display apparatus system may include a first display apparatus  100   a  and a second display apparatus  100   b.  In this case, at least one of the first and second display apparatuses  100   a  and  100   b  may be a stretchable display apparatus. For example, the second display apparatus  100   b  may be the stretchable display apparatus. In this case, at least a portion of the second display apparatus  100   b  may be stretched in a direction of the second edge E 2 . In detail, the second display apparatus  100   b  may be a manufactured apparatus in which an entire range of the second display apparatus  100   b  or a range inside a certain range from the second edge E 2  may be stretchable via a physical or electric signal. 
         [0073]    In this case, referring to  FIG. 5B , a degree of stretching of the second display apparatus  100   b  may be changed. In other words, the second display apparatus  100   b  may be stretched in a direction of the second edge E 2 . The second display apparatus  100   b  may be stretched until the second edge E 2  contacts with the first edge E 1  of the first display apparatus  100   a  or up to a position in which the second edge E 2  is not in contact with the first edge E 1 . In this case, the second display apparatus  100   b  may be stretched to a range which has been the space between the first and second display apparatuses  100   a  and  100   b.  As a result, the second display apparatus  100   b  may be extended and an effect may occur that the display range may be arranged in the space between the first display apparatus  100   a  and the second display apparatus  100   b.    
         [0074]    A case in which only the second display apparatus  100   b  is a stretchable display apparatus in  FIGS. 5A and 5B  is described as an example; however, the present inventive concept is not limited thereto, and both of the first and second display apparatuses  100   a  and  100   b  may be stretchable display apparatuses. In this case, at least a portion of the first display apparatus  100   a  may be stretched in a direction of the first edge E 1 . 
         [0075]    Alternatively, one of the first and second display apparatuses  100   a  and  100   b  may be a bendable display apparatus and the other may be a stretchable display apparatus. 
         [0076]    As described above, a display apparatus system of the present inventive concept may include the first and second display apparatuses  100   a  and  100   b  such that at least one of them include either a bendable display apparatus or a stretchable display apparatus. In this case, the display apparatus system may drive display apparatuses to a first state in which a space exists between the first and second display apparatuses  100   a  and  100   b,  or to a second state in which the space between the first and second display apparatuses is filled with the display range via an extension of at least one of the first and second display apparatuses  100   a  and  100   b.    
         [0077]      FIGS. 6A and 6B  are diagrams illustrating a display apparatus system according to embodiments. 
         [0078]    Referring to  FIG. 6A , the display apparatus system according to an embodiment may include a first and third display apparatuses  100   a  and  100   c  arranged on a fixed wall W, and a second display apparatus  100   b  arranged on a movable drawer D. 
         [0079]    The fixed wall W may denote an object which is relatively fixed with respect to the movable drawer D. In other words, a fixed wall W may demote a vehicle body which is relatively fixed in a moving vehicle, and the movable drawer D may denote a drawer existing inside the vehicle. The movable drawer D may denote a storage space which is manually or automatically movable, and may further denote various objects, which are relatively movable with respect to a fixed portion, such as a space into which a disc or a CD may be inserted and a portion of a wall designed to move. 
         [0080]    The movable drawer D in which the second display apparatus  100   b  may be arranged may be arranged at the center of the fixed wall W. In this case, the first display apparatus  100   a  may be arranged at a top portion of the fixed wall W and the third display apparatus  100   c  may be arranged at a bottom portion of the fixed wall W, based on the movable drawer D. 
         [0081]    In this case, referring to  FIG. 6B , the movable drawer D may move in a first direction with respect to the fixed wall W. Since the first through third display apparatuses  100   a  through  100   c  may be respectively fixed to the fixed wall W or the movable drawer D, the second display apparatus  100   b  may also move in the first direction with respect to the first and third display apparatuses  100   a  and  100   c.  The movable drawer D may move in the first direction with respect to the fixed wall W and become protruded from the fixed wall W, and may move into the inside of the fixed wall W via moving in a direction opposite to the first direction. In this case, a distance between an edge of the bottom portion of the first display apparatus  100   a  and that of the top portion of the second display apparatus  100   b  may be used as a center for description. When the movable drawer D is inside the fixed wall W, the distance between the edge of the bottom portion of the first display apparatus  100   a  and that of the top portion of the second display apparatus  100   b  may be a first distance which may be a minimum. In embodiments, when the movable drawer D is protruded at the maximum from the fixed wall W, the distance between the edge of the bottom portion of the first display apparatus  100   a  and the edge of the top portion of the second display apparatus  100   b  may be a second distance which may be a maximum. 
         [0082]    In this case, the first through third display apparatuses  100   a  through  100   c  may be a plurality of display apparatuses capable of displaying one image. In detail, when the movable drawer D is protruded from the fixed wall W (for example, when the distance between the edge of the bottom portion of the first display apparatus  100   a  and that of the top portion of the second display apparatus  100   b  is longer than the first distance), the first through third display apparatuses  100   a  through  100   c  may display respectively different images. When the movable drawer D is inside the fixed wall W (for example, the distance between the edge of the bottom portion of the first display apparatus  100   a  and that of the top portion of the second display apparatus  100   b  is the second distance), the first through third display apparatuses  100   a  through  100   c  may be driven to display one image. However, a space in which an image may not be displayed may exist between the first and second display apparatuses  100   a  and  100   b,  and between the second and third display apparatuses  100   b  and  100   c.  Due to this reason, one image which the first through third display apparatuses are to display may not be adequately displayed. To improve this effect, the display apparatus system may be operated so that at least one of the first through third display apparatuses  100   a  through  100   c  may be extended to have the display range arranged in the space between display apparatuses, when the movable drawer D is inside the fixed wall W (for example, when the distance between the edge of the bottom portion of the first display apparatus  100   a  and that of the top portion of the second display apparatus  100   b  is the first distance). A detailed description about this case will be given via  FIGS. 7A and 7B . 
         [0083]      FIGS. 7A and 7B  are diagrams illustrating changes of display apparatuses according to states of a display apparatus system according to embodiments. 
         [0084]    Referring to  FIG. 7A , the display apparatus system according to an embodiment may include the first and third display apparatuses  100   a  and  100   c  arranged on the fixed wall W, and the second display apparatus  100   b  arranged on the movable drawer D. In this case, a first space R 1  and a second space R 2  may exist between the fixed wall W and the movable drawer D. In detail, the first space R 1  may exist between the top portion of the fixed wall W in which the first display apparatus  100   a  may be arranged and the drawer D in which the second display apparatus  100   b  may be arranged, and the second space R 2  may exist between the bottom portion of the fixed wall W in which the third display apparatus  100   c  may be arranged and the drawer D in which the second display apparatus  100   b  may be arranged. When the movable drawer D is protruded from the fixed wall W as illustrated in  FIG. 7A , the first through third display apparatuses  100   a  through  100   c  may maintain an un-extended state. 
         [0085]    In this case, referring to  FIG. 7B , when the movable drawer D is inside the fixed wall W, at least a portion of the first through third display apparatuses  100   a  through  100   c  may be extended and the display range may be arranged in the first and second spaces R 1  and R 2 . For example, when the movable drawer D is inside the fixed wall W as illustrated in  FIG. 7B , the second display apparatus  100   b  may be extended both in a direction in which the first display apparatus  100   a  exists and in a direction in which the third display apparatus  100   c  exists, and the display range may be arranged in the first and second spaces R 1  and R 2 . In this case, the second display apparatus  100   b  may be a bendable display apparatus or a stretchable display apparatus. 
         [0086]    The display apparatus system may further include a controller to control whether to extend at least a portion of the first through third display apparatuses  100   a  through  100   c  or not. In embodiments, the display apparatus system may further include a sensor unit to identify respective arrangement states of the first through third display apparatuses  100   a  through  100   c.  In this case, the sensor unit may include various sensors to identify respective arrangements of the first through third display apparatuses  100   a  through  100   c.  For example, the sensor unit may include a sensor to measure a distance between one edge of the first display apparatus  100   a  and that of the second display apparatus  100   b.  Alternatively, the sensor unit may include an illuminance sensor to identify whether a certain display apparatus is protruded or not. 
         [0087]    As described above, the display apparatus system of the present inventive concept may include a plurality of display apparatuses arranged on one side of the fixed wall W and one side of the movable drawer D. When the movable drawer D is in a state of being protruded from the fixed wall W or of movement, the display apparatus system may have the plurality of display apparatuses maintain the un-extended state and have the movable drawer D adequately perform a role of a storage space. In embodiments, when the movable drawer D is inside the fixed wall W, the display apparatus system may have at least a portion of the plurality of display apparatuses extended, have the display range arranged in the spaces between the fixed wall W and the movable drawer D, and display a clear and full image. 
         [0088]      FIGS. 8, 9A, 9B, 10A, and 10B  are diagrams illustrating applications of a display apparatus system according to embodiments. 
         [0089]    Referring to  FIG. 8 , a vehicle dashboard  800  may be arranged in a vehicle. An entire portion or a portion of the vehicle dashboard  800  may include a display apparatus. In this case, the vehicle dashboard  800  may include various display apparatuses performing various functions such as an instrument panel, a center fascia, and a navigation panel. 
         [0090]    Referring to  FIG. 9A , the vehicle dashboard  800  may include a storage space and a center fascia. A first display apparatus  100   a  may be arranged on a front surface of the storage space. In embodiments, a second display apparatus  100   b  performing a function of the center fascia may be arranged adjacent to a top edge of the first display apparatus  100   a  in the vehicle dashboard  800 . When the storage space is not protruded as illustrated in  FIG. 9A , the first and second display apparatuses  100   a  and  100   b  may display one image. For example, the first and second display apparatuses  100   a  and  100   b  may display one image showing an operation state of an audio, an air conditioner, etc. of a vehicle. In this case, at least one of the first and second display apparatuses  100   a  and  100   b  may be extended and arrange the display range in a space between the first and second display apparatuses  100   a  and  100   b  to display a clear and full image via the first and second display apparatuses  100   a  and  100   b  (for example, an image without an empty range in which an image is not displayed in a middle portion). 
         [0091]    Referring to  FIG. 9B , when the storage space is protruded, the first and second display apparatuses  100   a  and  100   b  may display respectively different images or at least one of the first and second display apparatuses  100   a  and  100   b  may have an image display function disabled. In this case, both of the first and second display apparatuses  100   a  and  100   b  may not be extended. In other words, when the storage space is not protruded, at least one of the first and second display apparatuses  100   a  and  100   b  may have been extended, and a display apparatus in an extended state may be changed to the un-extended state when the storage space is protruded. Via this configuration, the vehicle dashboard  800  may include a practical storage space and, at the same time, may include a display apparatus with a smooth and attractive exterior design. 
         [0092]    In embodiments, referring to  FIG. 10A , a first and second display apparatuses  100   a  and  100   b  displaying information about vehicle operation may be arranged on the vehicle dashboard  800  on a driver&#39;s side and a third and fourth display apparatuses  100   c  and  100   d  displaying one image on the vehicle dashboard  800  on a passenger&#39;s side. Referring to  FIG. 10B , a space through which an air bag may be released may exist between the first and second display apparatuses  100   a  and  100   b.  The space through which an air bag may be released may exist also between the third and fourth display apparatuses  100   c  and  100   d.  In this case, when the air bag is not in use as illustrated in  FIG. 10A , at least one of the image-display surfaces (or image-display areas) of the first and second display apparatuses  100   a  and  100   b  may be extended and the display range may be arranged in the space between the first and second display apparatuses  100   a  and  100   b.  Likewise, when the air bag is not in use, at least one of the third and fourth display apparatuses  100   c  and  100   d  may be extended and the display range may be arranged in the space between the third and fourth display apparatuses  100   c  and  100   d.  Via this configuration, a space to implement necessary functions for a vehicle may be secured and, at the same time, a display apparatus with a smooth and attractive exterior design may be arranged on the vehicle dashboard.
