Backlight module with a heat conductive block

Abstract

A backlight module includes a bezel having at least one edge, a circuit board, one or more light emitting diodes connected to the circuit board for emitting light. Each light emitting diode has a light axis which is neither parallel nor vertical to the edge of the bezel. The backlight module utilizes a heat conductive block disposed between the bezel and the light emitting diode for transferring heat generated by the light emitting diode to the bezel.

1 . A backlight module, comprising: 
 a bezel having at least one edge;    a circuit board;    one or more light emitting diodes connected to the circuit board, each light emitting diode comprising a light axis, wherein the light axis of each light emitting diode is neither parallel nor vertical to the edge of the bezel; and    a non-rectangle heat conductive block disposed between the bezel and the light emitting diode, for transferring heat generated by the light emitting diode to the bezel.    
   
   
       2 . The backlight module of  claim 1 , wherein the bezel is made of metal.  
   
   
       3 . The backlight module of  claim 1 , wherein the circuit board is a flexible print circuit board.  
   
   
       4 . The backlight module of  claim 1 , wherein the non-rectangle heat conductive block is made of metal.  
   
   
       5 . The backlight module of  claim 1 , wherein the non-rectangle heat conductive block, the circuit board, and the bezel are adhered with a high polymer having high thermal conductivity.  
   
   
       6 . The backlight module of  claim 1 , wherein the non-rectangle heat conductive block is attached to the bezel.  
   
   
       7 . A liquid crystal display incorporating the backlight module of  claim 1 .  
   
   
       8 . The backlight module of  claim 1 , further comprising a light guide plate with a patterned surface.
