Description:
FIELD OF THE INVENTION  
       [0001]    The present invention relates to a display device, and more particularly to a display device for a notebook computer. 
       DESCRIPTION OF RELATED ART 
       [0002]    Portable computers, including laptop computers or notebook computers, have increased in popularity since their introduction to the electronics market. While many users prefer a tablet-type portable computer with a stylus as an input device, many other users prefer to have a portable computer with a full keyboard configuration depending upon the application for which the computer is being utilized. Therefore, users desire a portable computer that can be configured to operate either as a normal laptop computer with keyboard or pointing device input, or as a tablet computer with an electronic stylus or other touch-screen-type input device and/or OCR software. It is also generally desirable that the display of the portable computer be protected when the portable computer is being transported. 
         [0003]    Taiwan Patent No. M247895 discloses a rotatable display for a notebook computer including a hollow frame and a display horizontally rotatably mounted within the hollow frame. Two first pivoting members are symmetrically disposed at a top frame bar and a bottom frame bar of the hollow frame respectively. Two second pivoting members are symmetrically disposed at a top portion and a bottom portion of the display respectively, and the second pivoting members are respectively pivoted to the first pivoting members of the hollow frame. However, the display can only be rotated horizontally in the frame, and it can&#39;t satisfy the user&#39;s need of adjusting a height of the display. 
         [0004]    What is needed, therefore, is a display device which allows adjusting height of a display thereof. 
       SUMMARY OF THE INVENTION 
       [0005]    An exemplary display device includes a display, a frame, and two fixing members connecting the display to the frame. The frame includes two support arms, each of the support arms defines a longitudinal sliding slot, and the display is movable along the sliding slots of the frame. 
         [0006]    Other advantages and novel features will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings, in which:

     DETAILED DESCRIPTION OF THE INVENTION 
       [0012]    Referring to  FIGS. 1 to 3 , a display device for a notebook computer is provided in accordance with a preferred embodiment of the present invention. The display device includes a detachable frame  20  pivotally fixed to a base unit  10 , a display  30 , and a pair of fixing members  40 . 
         [0013]    The frame  20  includes two parallel support arms  26  each capable of being separated into two pieces  21 ,  22 . An inside surface of each support arm  26  defines a sliding slot  262  extending from a middle portion to a top portion of each support arm  26 . A wider recess  264  is defined in each support arm  26  communicating with the sliding slot  262 , and a rack  266  is installed in the recess  264  of each support arm  26 . In this embodiment, the rack  266  is made of rubber material. 
         [0014]    Each fixing member  40  includes a gear  42  and a pivot  44  operatively rotatably connected with the gear  42 . The pivot  44  may define a through hole therein for allowing a cable to extend therethrough. In this embodiment, the gear  42  and the pivot  44  are made of metal material. Rubber material is adhered to one end of each pivot  44  rotatably connected to a corresponding gear  42 , for increasing the friction between the gear  42  and the pivot  44 . Another free end of each pivot  44  forms male threads. The display  30  includes two sidewalls  31 , and a middle portion of each sidewall  31  defines a threaded fixing hole  37  for fixing the free end of the corresponding pivot  44 . 
         [0015]    Referring also to  FIGS. 1 and 3 , in assembly, the free ends of the pivots  44  of the fixing members  40  are respectively fixed to the fixing holes  37  of the sidewalls  31  of the display  30 . The frame  20  is detached into two pieces to receive the gears  42  of the fixing members  40  in the recesses  264  of the support arms  26  respectively, and the gears  42  are engaged with the racks  266  respectively. A cable, which is provided in the frame  20 , is extended through the through hole of the pivot  44  to electrically connect with the display  30 . The frame  20  is finally assembled, and the display  30  is movably mounted to the frame  20 . Then the frame  20  is pivotally fixed to the base  10 , and the cable electrically couples the display  30  to the base  10 . 
         [0016]    Referring to  FIG. 4 , the display  30  is received in the frame  20  entirely. The display device and the base  10  are combined as a typical clamshell notebook computer. When it is desired to adjust a height and an angle of the display  30  for better view, the display  30  is pulled in a plane defined by the frame  20 , causing the gears  42  to roll upwardly along the racks  266  of the support arms  26  respectively until the display  30  arrives at a desired height. The gears  42  are held in position within the corresponding racks  266  due to the friction therebetween, thereby the display  30  is held at the desired height in the frame  20 . The display  30  can also be rotated to a desired angle relative to the frame  20  and held in place due to the friction between the gears  42  and the pivots  44 . As shown in  FIG. 1 , the frame  20  is slantingly disposed relative to the base  10 , and the display  30  is vertically held in the frame  20  due to the friction between the gears  42  and the corresponding racks  266  and the corresponding pivots  44 . 
         [0017]    When it is desired to transform the typical notebook computer, as shown in  FIG. 4 , into a tablet-type computer, the display  30  is rotated 180 degrees in the frame  20 . The frame  20  is closed to the base  10 , and the display device and the base  10  can be used as a tablet computer as shown in  FIG. 5 . 
         [0018]    It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being preferred or exemplary embodiment of the invention.
