Description:
BACKGROUND OF THE INVENTION  
       [0001]     (a) Technical Field of the Invention  
         [0002]     The present invention is related to a liquid crystal display, and more particularly, to one that indicates the forward swivel of the display in horizontal status for the user to easily have visual contact with the signal connector and the power connector provided on the back of the display to facilitate connection of signal cable and power cable.  
         [0003]     (b) Description of the Prior Art  
         [0004]     As taught in the Taiwan patent publication # 35115   1 , the construction of liquid crystal displays generally available in the market is comprised of a display connected to a base for the adjustment of the elevation of the display. A pivoting structure is provided on the base to adjust the revolving angle. To keep cables connecting external signal source and power source from being exposed in the front of the display, signal and power connectors are provided on the back of the display.  
         [0005]     However, upon connecting those signal and power cables the back of the display must be swiveled to its left or right by the operation of the pivoting structure for the user to see those connectors since as limited by the forward swivel angle of the display due to block by the base. Whereas the base of the LCD of the prior art is disposed at the very central position of the display to prevent the display from tiling over due to its inherited weight, a space for swivel must be reserved to the peripheral of the LCD when the swivel of the display to its left or right with the base as the center is desired. Meanwhile, the radius of the space reserved must be greater than half a width of the display. On considering that the least space consumption is one of the primary advantages of the LCD, the reservation of a large space for swivel of the display as demanded by the connection of those signal and power cables, such advantage of least space consumption fails to be realized. Furthermore, the LCD is usually placed at where close to a wall and the peripherals including a mouse and a keyboard are provided at where below the front of the LCD. The arrangement makes it more difficult to swivel the display to its right or left. Accordingly a proper spacing must be reserved between the LCD and the wall, and the peripherals including the mouse and the keyboard must be removed from their original locations to make connection of those cables quite awkward.  
       SUMMARY OF THE INVENTION  
       [0006]     The primary purpose of the present invention is to provide an improved structure for an LCD that allows facilitated connection of signal and power cables. To achieve the purpose, the present invention is comprised of a display and a base. The display has provided on its back multiple signal connectors and power connectors to connect external signal and power sources; and provided on its back multiple hinges at a proper distance from the bottom of the display. The base includes a combination part to connect to those hinges of the display so to adjust the elevation angle of the display. An opening facing a gap provided on the front of the display is provided at where below the combination part and the depth of the gap is greater than the distance between those hinges and the bottom of the display.  
         [0007]     Accordingly, the gap allows the display to swivel forward to indicate horizontal status for the user to easily see those connectors provided on the back of the display to facilitate the connection of signal and power cables.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0015]     The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
         [0016]     Referring to  FIGS. 1A . and  1 B. through  4 , a preferred embodiment of the present invention is essentially comprised of a display ( 1 ) and a base ( 2 ) pivoted to the back of the display ( 1 ) to permit proper adjustment of the elevation angle of the display ( 1 ) n the base ( 2 ).  
         [0017]     Wherein, the display ( 1 ) includes a casing ( 10 ) containing a space ( 11 ) to accommodation circuit boards and electronic components; a rectangular hole ( 12 ) is disposed at the center of the back of the casing ( 10 ) to connect through the space ( 11 ); multiple combination holes ( 13 ) penetrating through the back of the casing ( 10 ) are provided at a proper spacing to the peripheral of the rectangular hole ( 12 ); a pivoting trough ( 14 ) is provided in recess on the back of the casing ( 10 ) at where close to the bottom of the display ( 1 ); a pivoting holder ( 140 ) is each protruding from both sides of the pivoting trough ( 14 ); a hinge ( 141 ) extending into the pivoting trough ( 14 ) is each provided on both pivoting holders ( 14 ); and multiple bolting holes ( 142 ) are provided on the hinge ( 141 ); and the hinge ( 141 ) is provided with two sections of swivel angles, respectively, leaning forward for 90˜5 degrees for the first section, and leaning forward for 5 degrees and leaning backward for 20 degrees for the second section.  
         [0018]     A back plate ( 15 ) provided over the rectangular hole ( 12 ) having provided on the peripheral of its inner surface multiple studs ( 16 ) with each stud ( 16 ) disposed on its top a combination rod ( 17 ) in a diameter slight smaller than that of the stud ( 16 ) to be inserted into its respective combination hole ( 13 ); the portion of the combination rod exposed from the inner side of the combination hole ( 13 ) is fused for fixation to the inner side of the casing ( 10 ) to prevent it from falling out of place while the stud ( 1   5 ) secures the back plate ( 15 ) to where allowing a certain range above the rectangular hole ( 12 ) for the spacing between any abutted studs ( 16 ) to define a sideway ventilation hole ( 18 ) that is connected through the space ( 11 ); and multiple through holes ( 10 ) are disposed on the back plate ( 15 ) to receive a signal connector ( 190 ) and a power connector ( 191 ) provided in the space ( 11 ) for connection to external signal and power sources.  
         [0019]     The base ( 2 ) includes a fixation plate ( 20 ), a support plate ( 21 ) and a combination plate ( 22 ). The fixation plate ( 20 ) is horizontally provided with one end disposed with a combination part ( 200 ) containing a locking slot ( 201 ) with a front opening to receive the installation by insertion of the hinge ( 141 ); multiple through holes ( 202 ) penetrating through the bottom of the base ( 2 ) are provided on the bottom of the locking slot ( 201 ) for a screw ( 203 ) to penetrate through and be locked into the bolting hole ( 141 ) provided on the hinge ( 141 ) so to combine the display ( 1 ) to the base ( 2 ).  
         [0020]     The support plate ( 21 ) is located below the fixation plate ( 20 ) approximately in parallel with the fixation plate ( 20 ) to define a gap ( 21 ) with its open facing forward and its depth greater than the distance between the hinge ( 141 ) of the display and the bottom of the display ( 1 ); a slotted hole ( 211 ) penetrating through the support plate ( 21 ) is provided on the support plate ( 21 ) to facilitate the access by a handle tool to tighten up the screw ( 203 ) into the through hole ( 202 ).  
         [0021]     The combination plate ( 22 ) in a semi-circular shape has its upper edge connected to one side of the fixation plate ( 20 ) and its lower edge connected to one side of the support plate ( 21 ) for the base ( 2 ) to approximately indicate a U shape with opening facing forward.  
         [0022]     Now referring to  FIGS. 3 and 5  with the display ( 1 ) learning forward for 90 degrees to indicate a horizontal status, the portion of the display below the hinge ( 141 ) is merely falling into the gap ( 210 ) of the base ( 2 ) for the user to easily see the signal connector ( 190 ) and the power connector ( 191 ) disposed on the back of the display ( 1 ) thus to facilitate the connection of signal and power cables. Meanwhile, the space required for the leaning forward of the display ( 1 ) is located at the very front of the display ( 1 ) where usually is related to a cleared space. Furthermore, when the display ( 10 ) leans forward for 90 degrees, its front side keeps a certain distance from the support plate ( 21 ) of the base ( 20 ) without being subject to the blocking by the peripherals including a mouse and a keyboard. Accordingly, while leaning forward the display ( 1 ), it is not necessary to relocate those peripherals to facilitate the connection of the signal and power cables.
