Receiving container for a display apparatus, backlight assembly and display apparatus having the receiving container, and method thereof

Abstract

A receiving container for a display apparatus receives a light-guiding unit and a light-generating unit disposed adjacent to a side surface of the light-guiding unit. The receiving container includes a bottom plate, a sidewall, and a gap-regulating portion. The light-guiding unit is disposed on the bottom plate. The sidewall faces the side surface of the light-guiding unit and is disposed at a peripheral portion of the bottom plate. The gap-regulating portion is formed at the sidewall or the bottom plate, to reduce a gap between the light-generating unit and the light-guiding unit. Thus, loss of light emitted by the point light source decreases so that power consumption of a backlight assembly and a display apparatus is reduced.

1 . A backlight assembly comprising:
 a light-guiding unit;   a light-generating unit comprising a printed circuit film and a light-generating unit having a printed circuit film and a light source mounted on the printed circuit film, the light-generating unit disposed adjacent to a side surface of the light-guiding unit; and   a receiving container comprising:
 a first side wall having a stepped portion to support the light-guiding unit; and 
 a second side wall having a gap-regulating portion regulating the distance between the light-generating unit and the light-guiding unit wherein the first and second side walls are interconnected. 
   
     
     
         2 . The backlight assembly of  claim 1 , wherein the gap-regulating portion is a protrusion protruding from the sidewall. 
     
     
         3 . The backlight assembly of  claim 2 , wherein the sidewall has a receiving groove, at which the light-generating unit is disposed, the sidewall formed to face the side surface of the light-guiding unit, the protrusion disposed at a base portion of the receiving groove. 
     
     
         4 . The backlight assembly of  claim 2 , wherein the protrusion comprises:
 a guiding surface slanted with respect to the bottom plate, the guiding surface guide the light-generating unit; and   a catching jaw surface securing the light-generating unit that is guided by the guiding surface.   
     
     
         5 . The backlight assembly of  claim 2 , wherein a portion of the printed circuit film overlaps with an edge of the light-guiding unit. 
     
     
         6 . The backlight assembly of  claim 1 , wherein the printed circuit film has a hole, and the gap-regulating portion is a guiding boss protruding from the sidewall and inserted into the hole. 
     
     
         7 . The backlight assembly of  claim 6 , wherein the guiding boss is slanted toward the sidewall. 
     
     
         8 . The backlight assembly of  claim 7 , wherein the sidewall has receiving grooves facing the side surface of the light-guiding unit, and the guiding boss is disposed on the sidewall between the receiving grooves. 
     
     
         9 . The backlight assembly of  claim 1 , wherein the gap-regulating portion is a guiding groove formed at a portion of the sidewall corresponding to the light-generating unit. 
     
     
         10 . The backlight assembly of  claim 9 , wherein the guiding groove faces the side surface of the light-guiding unit, and a base face of the guiding groove is slanted to guide the light-generating unit to the light-guiding unit. 
     
     
         11 . The backlight assembly of  claim 10 , wherein the light source comprises an inclined surface formed at an end portion of the light source. 
     
     
         12 . The backlight assembly of  claim 1 , wherein the light-guiding unit further comprises a light-diffusing pattern formed at the side surface of the light-guiding unit and corresponding to the light-generating unit. 
     
     
         13 . A display apparatus comprising:
 a backlight assembly comprising a light-guiding unit and a light-generating unit having a light source disposed adjacent to a side surface of the light-guiding unit and a printed circuit film on which the light-generating unit is mounted;   a receiving container comprising:
 a first side wall having a stepped portion to support the light-guiding unit; and 
 a second side wall having a gap-regulating portion regulating the distance between the light-generating unit and the light-guiding unit; and 
   a display panel disposed on the light-guiding unit,   wherein the first and second side walls are interconnected.   
     
     
         14 . The display apparatus of  claim 13 , wherein the gap-regulating portion protrudes from the sidewall and comprises:
 a catching jaw surface supporting the light-generating unit in a direction substantially perpendicular to the bottom plate and in a direction substantially perpendicular to the side surface of the light-guiding unit; and   a guiding surface guiding the light-generating unit to the catching jaw surface.   
     
     
         15 . The display apparatus of  claim 13 , wherein the printed circuit film is disposed between the light-generating unit and the display panel.
