Flat display apparatus with reduced electromagnetic radiation emission

Abstract

A flat display apparatus capable of decreasing electromagnetic radiation emission is presented. The flat display apparatus includes a flat display panel, a first receiving container, a driving part, a second receiving container and a ground member. The flat display panel displays an image. The first receiving container receives the flat display panel. The driving part is disposed on the first receiving container to drive a part of the flat display panel. The second receiving container covers the driving part to block an electromagnetic radiation radiating from the driving part. The ground member includes an extended protrusion protruding from a surface of the second receiving container and is disposed between the first receiving container and the second receiving container to electrically connect the first receiving container to the second receiving container. The second receiving container is electrically connected to an earth potential through the ground member and the first receiving container.

1 . A flat display apparatus comprising: 
 a flat display panel displaying an image;    a first receiving container receiving the flat display panel;    a driving part disposed on the first receiving container to drive a part of the flat display apparatus;    a second receiving container covering the driving part to block an electromagnetic radiation radiating from the driving part; and    a ground member including an extended protrusion protruding from a surface of the second receiving container, wherein the ground member is disposed between the first receiving container and the second receiving container to electrically connect the first receiving container to the second receiving container.    
   
   
       2 . The flat display apparatus of  claim 1 , wherein the driving part comprises a printed circuit board (PCB) that applies an electric signal to the flat display panel.  
   
   
       3 . The flat display apparatus of  claim 2 , wherein the second receiving container comprises a bottom surface and sidewalls protruding from the bottom surface to define a receiving space for the printed circuit board (PCB), and wherein the ground member is disposed between at least one of the sidewalls and the first receiving container.  
   
   
       4 . The flat display apparatus of  claim 3 , further comprising an extended portion that extends from the sidewalls in a plane substantially parallel to the bottom surface, wherein the ground member is disposed on the extended portion.  
   
   
       5 . The flat display apparatus of  claim 1 , further comprising a backlight assembly including a lamp assembly that generates light, an optical sheet assembly that improves optical characteristics of the light generated from the lamp, and wherein the flat display panel comprises a liquid crystal display (LCD) panel receiving the light that passes through the optical sheet assembly to display an image by using a liquid crystal disposed between substrates of the liquid crystal display panel.  
   
   
       6 . The flat display apparatus of  claim 5 , wherein the driving part comprises an inverter that drives the lamp assembly.  
   
   
       7 . The flat display apparatus of  claim 5 , wherein the second receiving container comprises a bottom surface and sidewalls protruding from the bottom surface and to define a receiving space for receiving the inverter, and wherein the ground member is disposed between at least one of the sidewalls and the first receiving container.  
   
   
       8 . A flat display apparatus comprising: 
 a display unit displaying an image;    a backlight assembly disposed under the display unit to supply the display unit with a light;    a bottom chassis disposed under the backlight assembly to receive the display unit and the backlight assembly;    an inverter disposed under the bottom chassis to apply an electric signal and an electric power to the backlight assembly;    an inverter case disposed under the bottom chassis, the inverter case including a bottom surface and sidewalls protruding from the bottom surface and to define a receiving space for the inverter, the inverter case blocking electromagnetic radiation generated from the inverter; and    a ground member including an extended protrusion protruding from a surface of the inverter case, the ground member being disposed between at least one the sidewalls and the bottom chassis to electrically connect the inverter case to the bottom chassis.    
   
   
       9 . The flat display apparatus of  claim 8 , wherein the sidewalls comprise an extended portion that extends in a plane parallel to the bottom surface, and the ground member is disposed on the extended portion.  
   
   
       10 . The flat display apparatus of  claim 8 , further comprising a mold frame disposed between the backlight assembly and the bottom chassis to support the backlight assembly.
