Electronic device and manufacturing method thereof

Abstract

An electronic device is provided. The electronic device includes a liquid-crystal display module, a diffuser, a prism sheet, a light guide, a back panel and an outer frame. The diffuser, the prism sheet and the light guide are sandwiched between the liquid-crystal display module and the back panel. The outer frame covers the liquid-crystal display module, wherein the outer frame includes a first frame member and a second frame member, a welded portion is formed between the first frame member and the second frame member, the outer frame includes an outer surface, and the outer surface includes a planar area at the welded portion.

What is claimed is: 
     
         1 . An electronic device, comprising:
 a liquid-crystal display module;   a diffuser;   a prism sheet;   a light guide;   a back panel, wherein the diffuser, the prism sheet and the light guide are sandwiched between the liquid-crystal display module and the back panel; and   an outer frame, covering the liquid-crystal display module, wherein the outer frame comprises a first frame member and a second frame member, a welded portion is formed between the first frame member and the second frame member, the outer frame comprises an outer surface, and the outer surface comprises a planar area at the welded portion.   
     
     
         2 . The electronic device as claimed in  claim 1 , wherein a width of the welded portion is shorter than or equal to 0.5 mm. 
     
     
         3 . The electronic device as claimed in  claim 2 , wherein the outer frame comprises an inner surface, the inner surface comprises a groove formed over the welded portion, and a width of the groove is longer than the width of the welded portion by 1 mm˜2 mm. 
     
     
         4 . The electronic device as claimed in  claim 1 , wherein the first frame member is connected to the second frame member by laser welding.
