     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
     Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings, so that those in the art can easily practice the exemplary embodiments. The present inventive concept is not limited to exemplary embodiments disclosed herein but may be implemented in different forms. 
     In the following exemplary embodiments, for the purpose of clarity, the same components are denoted by the same reference numerals throughout the drawings, and explanation thereof will be representatively given in a first exemplary embodiment but will be omitted in other embodiments. 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. 
       FIG. 1  is a schematic block diagram of a television  100  according to a first exemplary embodiment. As shown in  FIG. 1 , the television  100  includes an image receiving unit  110  which receives an image (e.g., an image signal), an image processing unit  120  which processes the received image, a display panel  130  which displays the processed image, a backlight  140  which illuminates the display panel  130  with light, and a power supply  200  which supplies power to the above components  110 ,  120 ,  130 , and  140 . 
     The image receiving unit  110  may include a broadcasting tuner which receives radio frequency (RF) signals from an external source by a wireless or wired connection. In some cases, the image receiving unit  110  may receive image signals in compliance with composite video, component video, super video, high definition multimedia interface (HDMI) standards and the like. 
     The image processing unit  120  processes the image signal transmitted from the image receiving unit  110  according to various preset image processes. Examples of the image processing processes performed by the image processing unit  120  may include decoding and/or encoding, de-interlacing, frame refresh rate conversion, scaling, noise reduction for improved image quality, detail enhancement, and so on. Of course, the above image processing is merely an example, and may be modified or improved in various manners. The image processing unit  120  may be a combination of individual elements which perform the above-described image processes independently, or alternatively may be an integrated type incorporating the above-described image processes. 
     The display panel  130  may include a liquid crystal panel. The liquid crystal panel includes a liquid crystal layer (not shown) interposed between two substrates (not shown) and displays an image by adjusting orientation of liquid crystal molecules in the liquid crystal layer. However, it is understood that the display panel  130  is not limited to a liquid crystal panel in another exemplary embodiment. For example, the display panel  130  may be a plasma display, an organic light emitting diode (OLED) display, or any flat panel display or the like. 
     The backlight unit  140  includes: a light guide plate  143  having an incidence surface into which light is incident, and an emitting surface through which the light is emitted to the display panel  130 ; a light source  141  which emits the light toward the incidence surface of the light guide plate  143 ; optical sheets (not shown) which adjust characteristics of the light emitted through the emitting surface of the light guide plate  143 ; and a light source driver  145  which drives the light source  141 . 
     The light source  141  may include, for example, at least one of light emitting diodes (LEDs) and cold cathode fluorescent lamps (CCFLs). Furthermore, the light source  141  may include red, green and blue LEDs or may implement white light by mixing red, green and blue light emitted from the respective color LEDs. The light source  141  may be arranged according to an edge type where the light source is arranged along an edge of the display panel  130 , a direct type where the light source is arranged in a rear side of the display panel  130 , or a hybrid type which is a combination of the edge type and the direct type. The light source driver  145  controls a switching ON/OFF of the light source  141 . 
     The power supply  200  receives commercial AC power S and converts the received AC power S into power used by at least one of the above-described image receiving unit  110 , image processing unit  120 , display panel  130 , and backlight unit  140 . 
     As shown in  FIGS. 2 and 3 , the power supply  200  may include: a circuit board  201 ; an input connector  210  which is provided on the circuit board  201  to receive the commercial AC power S; a rectifier  220  which rectifies the input AC power; a DC-DC converter  230  which converts a DC output from the rectifier  220  into DC power used by one or more of the components  110 ,  120 ,  130  and  140  in the television  100 ; and an output port  250  through which the DC power from the DC-DC converter  230  is output. 
     The output port  250  may be provided to output the DC power from the DC-DC converter  230  to at least one of the image receiving unit  110 , image processing unit  120 , display panel  130 , and/or backlight unit  140 . The output port  250  may also be detachably connected to power input connectors (not shown) provided in the components  110 ,  120 ,  130  and  140 . In some cases, the output port  250  may be omitted. 
     In this exemplary embodiment, the power supply  200  may further include an output connector  270  which is detachably coupled to the input connector  210 . The output connector  270  may be formed at one end portion of a cord L connected to the commercial AC power S in correspondence with the input connector  210 . In some cases, however, the output connector  270  and the input connector  210  may be formed on a non-correspondence basis. To this end, a transducer (not shown) which enables input and/or output of signals having different formats (so-called “gender”) may be interposed between the output connector  270  and the input connector  210 . 
     Moreover, in this exemplary embodiment, an electric outlet (not shown) connecting to the commercial AC power S may be formed at the other end portion of the cord L. The electric outlet (not shown) may be modified in various ways in consideration of different national standards. 
     The rectifier  220  may include rectifying diodes (not shown) which rectify the AC power into the DC power. The rectifier  220  may further include a smoothing part (not shown) which smoothes the DC power. 
     The DC-DC converter  230  may include a transformer (not shown) and a power switching element (not shown) which switches the transformer (not shown). 
     In this exemplary embodiment, all of the input connector  210 , rectifier  220 , DC-DC converter  230  and output port  250  may be arranged on a single circuit board. 
       FIG. 3  is a main part perspective view of the input connector  210  and electronic elements  223  constituting the rectifier  220  in the power supply  200  according to an exemplary embodiment. As shown in  FIG. 3 , the input connector  210  may be arranged on the circuit board  201  in such a manner that a height H of the input connector  210  projecting from a top surface  201   a  of the circuit board  201  is substantially equal to or less than a projecting height of at least one of the rectifier  220  and the DC-DC converter  230 . 
     In this exemplary embodiment, the projecting height of the rectifier  220  and the DC-DC converter  230  refers to a greatest height of respective electronic elements constituting the rectifier  220  and the DC-DC converter  230 , which projects from the top surface  201   a  of the circuit board  201 . 
     Here, the phase “substantially equal to” means that the projecting height H of the input connector  210  is equal to the projecting height of the rectifier  220  and/or the DC-DC converter  230  within a predetermined range. In this exemplary embodiment, the predetermined range may be about 5 mm. For example, even if the projecting height H is greater than the projecting height of the rectifier  220  and the DC-DC converter  230  by about 5 mm, it can be considered that the input connector  210 , the rectifier  220  and the DC-DC converter  230  have substantially the same height. 
     In this exemplary embodiment, at least one of the electronic elements  223  (for example, a capacitor and so on) constituting the rectifier  220  may be received in an element receiving hole  203  formed in the circuit board  201 . If the at least one electronic element  223  is provided on the circuit board  201  in a typical manner, its projecting height H1 will correspond to a body height which is greater than the projecting height H1, as shown in  FIG. 3 . 
     However, in the power supply  200  of this exemplary embodiment, the electronic element  223  may lay flat such that a lead of the electronic element  223  travels in parallel to the top surface  201   a  of the circuit board  201 . In addition, the electronic element  223  may be formed on a separate element board  224  to support the electronic element  223  stably, with the element board  224  communicably connected to the circuit board  201 . 
     This allows the projecting height H1 of the electronic element  223  from the top surface  201   a  of the circuit board  201  to be reduced, which may result in a thinner power supply  200 . In this exemplary embodiment, the electronic element  223  is merely one example of elements constituting the rectifier  220 , but it should be understood that other electronic elements constituting the power supply  200  may be provided on the circuit board  201 . 
     As shown in  FIGS. 3 and 4A to 4C , the input connector  210  includes: a connector casing  212 ; a plurality of insertion holes  213  formed in the connector casing  212 ; and a plurality of input terminals  211  including respective one end portions  211   d ,  211   e  and  211   f  accommodated in the plurality of insertion holes  213  of the connector casing  212  and respective other end portions  211   a ,  211   c  and  211   b  exposed out of the connector casing  212  to be connected to the circuit board  201 . The other end portions  211   a ,  211   c  and  211   b  of the plurality of input terminals  211  may be soldered to the circuit board  201 . In this exemplary embodiment, the other end portions  211   a ,  211   c  and  211   c  may be formed to be bent toward the circuit board  201 . 
     A mis-insertion preventing portion  213   a  which prevents the output connector  270  from being inserted erroneously may be formed in at least one of the plurality of insertion holes  213 . 
     In addition, the input connector  210  may be supported to the circuit board  201  by a solder bond between the other end portions  211   a ,  211   c  and  211   b  of the input terminals  211  and the circuit board  210 . For example, if an attachment/detachment cycle of the input/output connectors  210  and  270  is relatively long (for example, if the input/output connectors  210  and  270  are designed to be attached/detached by a serviceman other than a common user), the input connector  210  may be fixed to the circuit board  201  by the input terminal  211  without using a separate coupling pin which will be described later. 
     The input terminals  211  may include a (+) electrode terminal  211   a  which receives (+) power from the commercial AC power S, a ground terminal  211   c  for ground, and a (−) electrode terminal  211   b  which receives (−) power of the commercial AC power S. 
     The output connector  270  includes a plurality of projecting insertion portions  271 ,  272  and  273  which are adapted to be respectively inserted in the plurality of insertion holes  213  of the input connector  210 . The plurality of projecting insertion portions  271 ,  272  and  273  may be formed to correspond to the plurality of insertion holes  213  of the input connector  210 . If they do not correspond to each other, the plurality of projecting insertion portions  271 ,  272  and  273  and the plurality of insertion holes  213  can be communicably connected with each other through the above-mentioned transducer (not shown) (so-called “gender”) interposed between the output connector  270  and the input connector  210 . 
     Output terminals (not shown) through which the (+) power and (−) power of the commercial AC power S are output are formed in the plurality of projecting insertion portions  271  and  273 . The projecting insertion portion  272  may be formed as a ground terminal for ground. 
     The output connector  270  may include a pair of hooks  274  with the plurality of projecting insertion portions  271 ,  272  and  273  interposed therebetween. The pair of hooks  274  is inserted in the plurality of insertion holes  213  of the input connector  210  and engages with corresponding hitches (not shown) formed in the insertion holes  213 . Accordingly, the input/output connectors  210  and  270  are joined to each other to allow the commercial AC power S to be delivered to the power supply  200 . When end portions of the hooks  274  are pressed down and pulled, the hooks  274  are released from the hitches (not shown) to allow the output connector  270  to be removed from the input connector  210 . 
     The input connector  210  further includes coupling pins  214  provided on the connector casing  212 . In this exemplary embodiment, the connector casing  212  may be made of a plastic material and the coupling pins  214  may be made of a metal material, though it is understood that all embodiments are not limited thereto. The input connector  210  may be integrated with the coupling pins  214  by insert molding. The coupling pins  214  project toward the circuit board  201  to couple the input connector  210  to the circuit board  201 . The coupling pins  214  may be coupled to the circuit board  201  by soldering. 
     A power supply according to a second exemplary embodiment includes an input connector  310  as shown in  FIGS. 5 and 6 . A television according to the second exemplary embodiment includes: the power supply of the second exemplary embodiment; and an output connector  370  which supplies commercial AC power to the input connector  310 . Other components in this embodiment have the same configuration and operation as those in the first exemplary embodiment, and therefore, explanations thereof will not be repeated. In this exemplary embodiment, the input connector  310  has two input terminals  312 , while the input connector  210  described in the first exemplary embodiment has three input terminals  211 . 
     The input connector  310  includes: a connector casing  311 ; an insertion hole  313  formed in the connector casing  311 ; and a plurality of input terminals  312  having one end portions  312   c  and  312   b  accommodated within the insertion hole  313  and other end portions  312   a  exposed out of the connector casing  311  to be inserted in the circuit board  201 . 
     The other end portions  312   a  of the plurality of input terminals  312  may be coupled to the circuit board  201  by soldering. The input connector  310  can be supported to the circuit board  201  by soldering between the input terminals  312  an the circuit board  201 . 
     The insertion hole  313  may be partitioned into a plurality of insertion holes  313   a ,  313   b  and  313   c  into which a plurality of projecting insertion portions  371 ,  372  and  373  of the output connector  370  is respectively inserted. The insertion hole  313  may further include a mis-insertion preventing portion  313   d  which prevents the output connector  370  from being inserted erroneously. 
     Output terminals  375  for (+) and (−) power output of the commercial AC power S are respectively formed within the projecting insertion portions  371  and  373 , which are disposed at both sides of the output connector  370 , of the plurality of projecting insertion portions  371 ,  372  and  373 . 
     Exposure holes  376  for exposing a portion of the output terminals  375  externally may be formed at one side of the projecting insertion portions  371  an  373  at which the output terminals  375  are formed. The exposure holes  375  may be formed to direct to the top surface of the circuit board  201 . 
     In addition, the output connector  370  may further include a plurality of hooks  374  at both sides, with the plurality of projecting insertion portions  371 ,  372  and  373  interposed therebetween. The input connector  310  may further include a plurality of hitches  315  provided opposite to the plurality of hooks  374 . 
     When the output connector  370  is inserted in the input connector  310 , hooking pieces  374   b  formed at one end portions of the hooks  374  climb over inclined surfaces  315   a  of the hitches  315  and engage with the hitches  315 . Accordingly, the input/output connectors  310  and  370  can be stably joined to each other. On the other hand, when the output connector  370  is pulled while pressing down grippers  374   a  formed at the other end portions of the plurality of hitches  315 , the output connector  370  can be detached from the input connector  310  as the hitches  315  are released from the hooks  374 . 
     The input connector  310  may further include coupling pins  314  for more stably coupling the input connector  310  to the circuit board  201  in addition to the soldering of the input terminals  312  to the circuit board  201 . The coupling pins  314  may be provided to project from the connector casing  311  toward the circuit board  201 . The coupling pins  314  may be made of a metal material. The coupling pins  314  and the connector casing  311  may be extruded by insert molding. Furthermore, the coupling pins  314  may be inserted in and coupled to the circuit board  201  by soldering. 
     In addition, the input connector  310  may further include a shield  316  which prevents the input terminals  312  from being exposed in the upper direction of the circuit board  201 . 
       FIG. 6  is a sectional view showing a state where the output connector  370  is joined to the input connector  310  according to an exemplary embodiment. As shown in  FIG. 6 , the output terminal  375  of the output connector  370  contacts the input terminal  312  of the input connector  310 . 
     Hereinafter, a power supply  200   a  according to a third exemplary embodiment will be described with reference to  FIGS. 7 and 8A to 8B . Referring to  FIGS. 7 and 8A to 8B , an output connector  470  is formed at an end portion of a cord L connected to the commercial AC power. Only (+) and (−) power terminals without any ground terminal may be provided in the output connector  470 . 
     In this exemplary embodiment, the power supply  200   a  includes an input connector  410  and a television including the power supply  200   a  includes the output connector  470 . 
     The input connector  410  includes: a connector casing  411 ; an insertion hole  413  formed in the connector casing  411 ; and a plurality of input terminals  412  having one end portions accommodated in the insertion hole  413  and other end portions  412   b  bent toward the circuit board  201 . 
     In this exemplary embodiment, the insertion hole  413  may include a rectangular hoop  413   a  with substantially right-angled edges and a circular hoop  413   b . The rectangular hoop  413   a  serves to prevent the output connector  470  from being inserted erroneously. It is understood that the shape of the insertion hole  413  is not limited to the rectangular hoop  413   a  and the circular hoop  413   b , and may vary in other embodiments. For example, the shape of the insertion hole  413  may be modified according to national standards. 
     The input connector  410  may be accommodated in a connector accommodating hole  201   b  of the circuit board  201 . The connector accommodating hole  201   b  may be formed by cutting out one side of the circuit board  201 . When the input connector  410  is accommodated in the circuit board  201  by a thickness (t) of the circuit board  201 , a height (K) of the input connector  410  from the top surface  201   a  of the circuit board  201  becomes lower than a height (J) of the input connector  410  itself. This may result in a thinness of the power supply  200   a.    
     The input connector  410  may further include board hooks  417  which can be hooked to a hoop of the connector accommodating hole  201   b  of the circuit board  201 . The board hooks  417  prevent the input connector  410  from being upwardly separated from the circuit board  201 . The board hooks  417  may be respectively formed at both sides of the connector casing  411  with the connector accommodating hole  201   b  interposed therebetween. 
     The input connector  410  may further include arms  418  extending from the connector casing  411  in the plane direction of the circuit board  201 . The arms  418  may be respectively formed at both sides of the connector casing  411  with the connector accommodating hole  201   b  interposed therebetween. 
     In addition, the input connector  410  may further include coupling pins  416  which couple the connector casing  411  to the circuit board  201 . In this exemplary embodiment, the coupling pins  416  may be made of a metal material and the connector casing  411  may be made of a plastic resin. The input connector  410  may be formed to be integrated with the coupling pins  416  by insert molding. The coupling pins  416  may be coupled to the circuit board  201  by soldering. This allows the input connector  410  to be more stably supported to the circuit board  201 . 
     In addition, the input connector  410  may further include fastening holes  415  in which fasteners (not shown) which fasten the connector casing  411  to the circuit board  201  are inserted. This allows the input connector  410  to be stably coupled to the circuit board  201  even when a common user relatively frequently attaches/detaches the output connector  470  to/from the input connector  410 . In this exemplary embodiment, the fastening holes  415  may be formed with the connector accommodating hole  201   b  interposed therebetween. The fastening holes  415  and the coupling pins  416  may be formed in the arms  418 . 
     The input connector  410  may further include a shield  414  which prevents the input terminals  412  from being exposed in the upper direction of the circuit board  201 . The shield  414  may be integrated with the connector casing  411 . This eliminates a need to form a separate shield in the circuit board, which may result in improved assembleability. 
       FIG. 8A  is an enlarged view of main parts of the circuit board  201  on which the input connector  410  is mounted. Referring to  FIG. 8A , around the connector accommodating hole  201   b  may be formed board fastening holes  201   c  corresponding to the fastening holes  415  of the input connector  410 ; pin holes  201   d  in which the coupling pins  416  are inserted; and terminal holes  201   e  in which the other end portions  412   b  of the input terminals  412  are inserted. 
     Hereinafter, a television  100   a  according to the third exemplary embodiment will be described with reference to  FIGS. 9 and 10 .  FIG. 9  is a schematic rear view of the television  100   a  and  FIG. 10  is an enlarged perspective view of main parts in  FIG. 9 . In the third exemplary embodiment, the television  100   a  includes the above-described power supply  200   a.    
     The television  100   a  further includes a front cover (not shown); and a rear cover  170  which is detachably coupled to the front cover (not shown). Between the front cover and the rear cover  170  may be accommodated the image receiving unit ( 110  in  FIG. 1 ); the image processing unit ( 120  in  FIG. 1 ); the display panel ( 130  in  FIG. 1 ); the backlight unit ( 140  in  FIG. 1 ) (all of which have been described in the first exemplary embodiment); and the power supply  200   a . The display panel  130  is accommodated in such a manner that a screen displayed on the front cover is exposed. At least one of the front cover and the rear cover  170  may be made of an aluminum material. This allows heat generated in the backlight unit  140  to be more smoothly exhausted externally. 
     The rear cover  170  may further include an inwardly-depressed portion  173 . At one side of the depressed portion  173  may be formed a cover insertion hole  173   a  in which the output connector  470  is inserted. 
     The power supply  200   a  may be supported between the front cover and the rear cover  170  such that the insertion holes  413  of the input connector  410  can communicate to the cover insertion hole  173   a . Accordingly, power can be supplied to the television  100   a  when a common user inserts the output connector  470  in the cover insertion hole  173   a  of the depressed portion  173 . 
     While a so-called LCD television using a liquid crystal display panel as one example of display panels has been shown and described above, it is to be understood that the above-described input connector  210 ,  310 , and  410  and output connector  270 ,  370 , and  470  can be employed for other televisions using a plasma display panel (PDP), an active-matrix organic light emitting diode (AMOLED) panel, or other types of display panels. 
     In addition, it is to be understood that the scheme for cutting out a portion of the circuit board  201  and accommodating the connector  410  in the portion as described in the third exemplary embodiment can be equally applied to the first and second exemplary embodiments. 
     Although a few exemplary embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
