Module with FPC and manufacturing method for the same

Abstract

The FPC that is designed to have the special shape, an elastic portion, can shorten its length by elastic force after it is turned over to the reverse side of the light source unit for achieving the purposes without wasting any space of the LCD module and incurring the inconvenience of user.

1 . A flexible printed circuit board (FPC), including an elastic portion, wherein the FPC has a first axial length when no force is applied, and wherein when a pulling force is applied to the FPC, the elastic portion is extended along an extending direction such that the FPC has a second axial length longer than the first axial length.  
   
   
       2 . The FPC according to  claim 1 , wherein when the pulling force is released, the axial length of the FPC changes from the second axial length into a third axial length shorter than the second axial length due to elastic force.  
   
   
       3 . The FPC according to  claim 1 , wherein the elastic portion includes jag, tooth, rectangle, step or combinations thereof.  
   
   
       4 . The FPC according to  claim 1 , wherein the material of said FPC is selected from the group consisting of polymer and polyester.  
   
   
       5 . The FPC according to  claim 1 , wherein the FPC comprises signal lines.  
   
   
       6 . The FPC according to  claim 1 , wherein the FPC comprises power lines.  
   
   
       7 . A method for manufacturing a module with flexible printed circuit board (FPC), comprising: 
 providing a first device and a second device on the first device;    providing a first flexible printed circuit board (FPC) to connect an edge of the first device, wherein the first FPC includes an elastic portion;    providing a second FPC to connect an edge of the second device;    connecting the first and second FPCs at a connection end while the elastic portion of the first FPC is extended along an extending direction by a pulling force; and    turning over the first and second FPCs and the connection end to a reverse side of the first device while the extended elastic portion of the first FPC is restored or shortened.    
   
   
       8 . The method as claimed in  claim 7 , wherein the first and second FPCs are connected by bonding or soldering.  
   
   
       9 . A module with flexible printed circuit board (FPC), comprising: 
 a first device;    a second device on said first device;    a first flexible printed circuit board (FPC) connected to said first device, wherein the first FPC includes an elastic portion; and    a second FPC connected to said second device,    wherein the first and second FPCs are connected at an connection end, and    wherein the connection end, a part of the first FPC, and a part of the second FPC are positioned under a reverse side of the first device.    
   
   
       10 . The module with FPC according to  claim 9 , wherein the elastic portion includes jag, tooth, rectangle, step or combinations thereof.  
   
   
       11 . The module with FPC according to  claim 9 , wherein the material of said first and second FPCs are selected from the group consisting of polymer and polyester.  
   
   
       12 . The module with FPC according to  claim 9 , wherein the first device is a light source unit.  
   
   
       13 . The module with FPC according to  claim 12 , wherein the first device is a backlight unit.  
   
   
       14 . The module with FPC according to  claim 13 , wherein the first device is an LED unit.  
   
   
       15 . The module with FPC according to  claim 9 , wherein the second device is a panel.  
   
   
       16 . The module with FPC according to  claim 15 , wherein the second device is an LCD panel.  
   
   
       17 . The module with FPC according to  claim 9 , wherein the first and second FPCs are connected by bonding or soldering.  
   
   
       18 . An LCD module with flexible printed circuit board (FPC), comprising: 
 a backlight unit;    an LCD panel on the backlight unit;    a first FPC connected to the backlight unit, wherein the first FPC includes an elastic portion; and    a second FPC connected to the LCD panel,    wherein the first and second FPCs are connected at an connection end, and    wherein the connection end, a part of the first FPC, and a part of the second FPC are positioned under a reverse side of the backlight unit.
