Patent Abstract:
A LCD monitor, which has multiple light guides matched with a respective LED lamp and peripherally blocked with light blocking filters so that different background colors are shown in different display zones of the LCD panel thereof.

Full Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to LCD monitors and more particularly, to a LCD monitor that has multiple background colors. 
         [0003]    2. Description of the Related Art 
         [0004]    A regular LCD monitor has a reflector at the back side to reflect light from the backlight module, thereby enhancing the background light. However, the whole display panel of a conventional LCD monitor simply provided one background color, light grey or yellow. This monochromic background color is monotonous, showing little visual effect. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention has been accomplished under the circumstances in view. It is therefore the main object of the present invention to provide a LCD monitor, which shows different background colors in multiple display zones on the LCD panel. According to the present invention, the LCD monitor comprises a plurality of light guides arranged on a bottom side of a LCD panel thereof, multiple LED (light emitting diode) lamps respectively arranged at one side of each of the light guides and controllable to emit different colors of light to the light guides respectively for showing different background colors in different display zones on the LCD panel, and multiple blocking filters respectively attached to the periphery of the light guides to block the light of the LED lamps in the associating light guides respectively and to prohibit the light of each of the LED lamps from passing out of the associating light guide.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0009]    Referring to  FIGS. 1˜3 , a LCD monitor in accordance with the present invention is shown comprising a LCD panel  10 , a plurality of light guides  21 ˜ 26  arranged on the bottom side of the LCD panel  10 , multiple LED (light emitting diode) lamps  27  respectively arranged at one side of each of the light guides  21 ˜ 26  and controlled to emit different colors of light to the associating light guides  21 ˜ 26 , and multiple blocking filters  20  respectively attached to the periphery of the light guides  21 ˜ 26  to block the light of the associating LED lamp  27  in the associating light guide and to prohibit the light of the associating LED lamp  27  from passing through the other light guides. 
         [0010]    Referring to  FIGS. 2 and 3  again, the light guides  21 ˜ 26 , the blocking filters  20  and the LED lamp  27  are abutted against one another on a same plane, and then covered with a light diffuser film  18  at the top side and a light reflector film  28  at the bottom side, and then the LCD panel  10  is attached to the top side of the light diffuser film  18 , and then the assembly thus obtained is installed in a circuit board  30  and packed in a frame  31 . Thus, the LCD panel  10  and the LED lamps  27  are electrically connected to the circuit board  30 , and the circuit board  30  provides the necessary working voltage to the LCD panel  10  and the LED lamps  27 . 
         [0011]    Further, the LCD panel  10  has multiple display zones  11 ˜ 16  corresponding to the light guides  21 ˜ 26 . The display zones  11 ˜ 16  each has bright dots  17  controllable by the circuit board  30  to display or not to display letters or graphics (because the function of the bright dots of the LCD panel  10  to display or not to display is of the known art and not within the scope of the present invention, no further detailed description in this regard is necessary). For example, the first display zone  11  is adapted to display English letters; the second display zone  12  is adapted to display graphics; the third through sixth display zones  13 ˜ 16  are adapted to display numerals. 
         [0012]    When the LED lamps  27  are turned on, the light of the LED lamps  27  passes through the associating light guides  21 ˜ 26 , the light reflector film  28  reflects light toward the light diffuser film  18 , and the light diffuser film  18  diffuses light into the whole area of the LCD panel  10 . Further, the LED lamps  27  can be controlled to emit different colors of light into the associating light guides  21 ˜ 26 . By means of the effect of the blocking filters  20 , each of the light guides  21 ˜ 26  is illuminated with a respective color of light, and therefore the display zones  11 ˜ 16  of the LCD panel  10  show different background colors A˜F, showing a unique visual effect. 
         [0013]    Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
