CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to and the benefit of Korean Patent Application No. 10-2015-0121248, filed on Aug. 27, 2015 in the Korean Intellectual Property Office (KIPO), the content of which is incorporated herein in its entirety by reference. 
     BACKGROUND 
     1. Field 
     Aspects of the present invention relate to a display device and an electronic device including the same. 
     2. Description of the Related Art 
     Flat panel display (FPD) devices are widely used as display devices of electronic devices because FPD devices are relatively lightweight and thin compared to cathode-ray tube (CRT) display devices. Examples of FPD devices are liquid crystal display (LCD) devices, field emission display (FED) devices, plasma display panel (PDP) devices, and organic light emitting display (OLED) devices. The OLED devices have been spotlighted as next-generation display devices because the OLED devices have various advantages, such as a wide viewing angle, a rapid response speed, a thin thickness, low power consumption, etc. 
     A display panel includes a plurality of pixels. A plurality of signals may be provided to the pixels through lines formed in the display panel to drive the pixels. As the size and resolution of the display panel increases, the length of the lines formed in the display panel increases and a space between the lines decreases. Thus, the signals provided to pixels through the lines may be delayed due to a resistance of the lines and capacitances formed between the lines.

     DETAILED DESCRIPTION 
     Hereinafter, the present inventive concept will be explained in detail with reference to the accompanying drawings. 
       FIG. 1  is a block diagram illustrating a display device according to some example embodiments of the present invention, and  FIG. 2  is a circuit diagram illustrating an example of a pixel included in the display device of  FIG. 1 . 
     Referring to  FIGS. 1 and 2 , a display device  100  may include a display panel  110 , a scan driver  122 ,  124 ,  126 , and  128 , a data driver  130 , an emission controller  142 ,  144 ,  146 , and  148 , and a timing controller  150 . 
     The display panel  110  may include a first display area  112  and a second display area  114  that include a plurality of pixels Px. A plurality of data lines DL, a plurality of scan lines SL, and a plurality of emission control lines EML may be formed in each of the first display area  112  and the second display area  114 . The pixels Px may be formed at crossing regions of the data lines DL and the scan lines SL in the first display area  112  and the second display area  114 . Referring to  FIG. 2 , each of the pixels Px may include an organic light emitting diode EL, a switching transistor T 1 , a storage capacitor C, a driving transistor TD and an emission transistor TE. In this example, the driving transistor TD may control a driving current flowing through the organic light emitting diode EL based on the data signal DATA. The data signal DATA is provided to the driving transistor TD via the data line DL in response to the scan signal SCAN, where the scan signal SCAN is provided via the scan line SL. The emission transistor TE may be disposed between the organic light emitting diode EL and the driving transistor TD. The emission transistor TE may provide the driving current to the organic light emitting diode EL in response to an emission control signal EMIT provided through the emission control line EML. Thus, the organic light emitting diode EL may emit light. 
     The scan driver  122 ,  124 ,  126 , and  128  may provide the scan signals SCAN to the pixels Px. The scan driver  122 ,  124 ,  126 , and  128  may be formed at sides of the first display area  112  and at sides of the second display area  114 . The scan driver  122 ,  124 ,  126 , and  128  may include first scan drivers  122  and  124 , and second scan drivers  126  and  128 . 
     In some example embodiments, the first scan drivers  122  and  124  may be formed at both sides of the first display area  112 , and the second scan drivers  126  and  128  may be formed at both sides of the second display area  114 . The first scan drivers  122  and  124  may be coupled to the scan lines SL in the first display area  112 . The first scan drivers  122  and  124  may provide the scan signals SCAN to the switching transistor T 1  of the pixels Px formed in the first display area  112  through the scan lines SL in the first display area  112 . Here, the first scan driver  124  of the first scan drivers  122  and  124  may be formed in a non-display area disposed between the first display area  112  and the second display area  114 . The second scan drivers  126  and  128  may be coupled to the scan lines SL in the second display area  114 . The second scan drivers  126  and  128  may provide the scan signals SCAN to the switching transistor T 1  of the pixels Px formed in the second display area  114  through the scan lines SL in the second display area  114 . Here, the second scan driver  128  of the second scan drivers  126  and  128  may be formed in the non-display area disposed between the first display area  112  and the second display area  114 . 
     As described above, the scan signals SCAN may be provided to both sides of the scan lines SL by forming the first scan drivers  122  and  124  at both sides of the first display area  112  and forming the second scan drivers  126  and  128  at both sides of the second display area  114 . Thus, a delay of the scan signals SCAN resulting from resistance of the scan lines SL and capacitance between the scan lines SL may be reduced. 
     In some example embodiments, the first scan driver  122  and  124  may be formed at one side of the first display area  112  and the second scan driver  126  and  128  may be formed at one side of the second display area  114 . Although the scan driver that includes two first scan drivers  122  and  124  is described in  FIG. 1 , the scan driver may include one first scan driver. For example, the scan driver may include one first scan driver  122  disposed at a left side of the first display area  112  or one first scan driver  124  disposed at a right side of the first display area  112  (i.e., the non-display area formed between the first display area  112  and the second display area  114 ). Further, although the scan driver that includes two second scan drivers  126  and  128  is described in  FIG. 1 , the scan driver may include one second scan driver. For example, the scan driver may include one second scan driver  126  disposed at a right side of the second display area  114  or one second scan driver  128  disposed at a left side of the second display area  114  (i.e., the non-display area formed between the first display area  112  and the second display area  114 ). 
     The data driver  130  may provide the data signal DATA to the pixels Px. The data driver may convert an image signal provided from an external device into the data signal DATA. Specifically, the data driver  130  may convert the image signal to an analog voltage corresponding to a grayscale value. The data driver  130  may provide the analog voltage to the pixels in the first display area  112  and the second display area  114  as the data signal DATA. The timing controller  150  may generate a control signal CTL that controls the scan driver  122 ,  124 ,  126 , and  129 , the data driver  130 , and the emission controller  142 ,  144 ,  146 , and  148 . 
     The emission controller  142 ,  144 ,  146 , and  148  may provide the emission control signals EMIT to the pixels Px. The emission controller  142 ,  144 ,  146 , and  148  may formed at a side of the first display area  112  and at a side of the second display area  114 . The emission controller  142 ,  144 ,  146 , and  148  may include a first emission controller  142  and  144 , and a second emission controller  146  and  148 . 
     In some example embodiments, the first emission controllers  142  and  144  may be formed at both sides of the first display area  112  and the second emission controllers  146  and  148  may be formed at both sides of the second display area  114 . The first emission controllers  142  and  144  may be coupled to the emission control lines EML in the first display area  112 . The first emission controllers  142  and  144  may provide the emission control signals EMIT to the emission transistor TE of the pixels Px formed in the first display area  112  through the emission control lines EML in the first display area  112 . Here, the first emission controller  144  of the first emission controllers  142  and  144  may be formed in the non-display area disposed between the first display area  112  and the second display area  114 . The second emission controllers  146  and  148  may be coupled to the emission control lines EML in the second display area  114 . The second emission controllers  146  and  148  may provide the emission control signals EMIT to the emission transistor TE of the pixels Px formed in the second display area  114  through the emission control lines EML in the second display area  114 . Here, the second emission controller  148  of the second emission controllers  146  and  148  may be formed in the non-display area disposed between the first display area  112  and the second display area  114 . As described above, the emission control signals EMIT may be provided to both sides of the emission control lines EML by forming the first emission controllers  142  and  144  at both sides of the first display area  112  and forming the second emission controllers  146  and  148  at both sides of the second display area  114 . Thus, a delay of the emission control signals EMIT resulting from resistance of the emission control lines EML and capacitance between the emission control lines EML may be reduced. 
     In other example embodiments, the first emission controller  142  and  144  may be formed at one side the first display area  112  and the second emission controller  146  and  148  may be formed at one side of the second display area  114 . Although the emission controller that includes two first emission controllers  142  and  144  is described in  FIG. 1 , the emission controller may include only one first emission controller. For example, the emission controller may include one first emission controller  142  disposed at a left side of the first display area  112  or one first emission controller  144  disposed at a right side of the first display area  112  (i.e., in the non-display area formed between the first display area  112  and the second display area  114 ). Further, although the emission controller that includes two second emission controllers  146  and  148  is described in FIG.  1 , the emission controller may include only one second emission controller. For example, the emission controller may include one second emission controller  146  disposed at a right side of the second display area  114  or one second emission controller  148  disposed at a left side of the second display area  114  (i.e., in the non-display area formed between the first display area  112  and the second display area  114 ). 
     Generally, the scan driver  122 ,  124 ,  126 , and  128  and the emission controller  142 ,  144 ,  146 , and  148  may be formed at both sides of the display panel  110 . As the size and resolution of the display panel  110  increases, the length of lines (e.g., scan lines, emission lines, data lines, . . . ) increases and the spacing between the lines decreases. Here, signals (e.g., scan signals, emission control signals, data signals . . . ) provided to the pixels Px through the lines may be delayed as a result of line resistance and capacitances formed between the lines. The display device  100  according to example embodiments may divide the display area of the display panel  110  into the first display area  112  and the second display area  114 , and may additionally form the scan driver  122 ,  124 ,  126  and  128  and the emission controller  142 ,  144 ,  146 , and  148  in the non-display area that is formed between the first display area  112  and the second display area  114 . Thus, the scan signals SCAN and the emission control signals EMIT may be stably provided to the pixels Px without delay or with reduced (e.g., minimal) delay.

In some example embodiments, the first emission controllers may be formed at both sides of the first display area and the second emission controllers may be formed at both sides of the second display area. The first emission controllers may be coupled to the emission control lines in the first display area. The first emission controller may include a plurality of emission controlling circuits. The emission controlling circuit of the first emission controller may be coupled to the emission control lines in the first display area. The emission controlling circuit of the first emission controller may provide the emission control signal to both sides of the emission control line coupled to the pixels in the first display area. The second emission controllers may be coupled to the emission control lines in the second display area. The second emission controller may include the plurality of emission controlling circuits. The emission controlling circuit of the second emission controller may be coupled to the emission control lines in the second display area. The emission controlling circuit of the second emission controller may provide the emission control signal to both sides of the emission control line coupled to the pixels in the second display area. In other example embodiments, the first emission controller may be formed at one side of the first display area and the second emission controller may be formed at one side of the second display area. The first emission controller may be formed at the left side or right side of the first display area. Here, the left side or the right side of the first display area may be the non-display area formed between the first display area and the second display area. The second emission controller may be formed at the left side or right side of the second display area. Here, the left side or the right side of the second display area may be the non-display area formed between the first display area and the second display area. 
     The data driver may provide a data signal to the pixels in the first display area and the second display area. The timing controller may generate a control signal that controls the scan driver, the data driver, and the emission controller. 
     As described above, the electronic device  200  of  FIG. 5  may divide the display area into the first display area and the second display area and may additionally form the scan driver and the emission controller in the non-display area formed between the first display area and the second display area. Thus, the scan signals and the emission control signals may be stably provided to the pixels without delay or with reduced (e.g., minimal) delay.

For example, the present inventive concept may be applied to a computer monitor, a laptop, a digital camera, a cellular phone, a smart phone, a smart pad, a television, a personal digital assistant (PDA), a portable multimedia player (PMP), a MP3 player, a navigation system, a game console, a video phone, and/or the like. 
     It will be understood that, although the terms “first”, “second”, “third”, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section, without departing from the spirit and scope of the inventive concept. 
     The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of the inventive concept. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “include,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. Further, the use of “may” when describing embodiments of the inventive concept refers to “one or more embodiments of the inventive concept.” 
     It will be understood that when an element or layer is referred to as being “connected to” or “coupled to” another element, it can be directly connected to or coupled to the other element, or one or more intervening elements may be present. When an element is referred to as being “directly connected to” or “directly coupled to” another element, there are no intervening elements present. 
     As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively. 
     The display device and/or any other relevant devices or components, such as the scan and emission controllers and processor, according to embodiments of the present invention described herein may be implemented utilizing any suitable hardware, firmware (e.g. an application-specific integrated circuit), software, or a suitable combination of software, firmware, and hardware. For example, the various components of the display device may be formed on one integrated circuit (IC) chip or on separate IC chips. Further, the various components of the display device may be implemented on a flexible printed circuit film, a tape carrier package (TCP), a printed circuit board (PCB), or formed on a same substrate.
