Viewing panel for an electronic device

Abstract

An outer viewing panel includes a display window and a supporting body integrated with the display window. The display window is made of sapphire and the supporting body is made of ceramic for increased hardness and durability. The supporting body is integrally formed with the supporting body by a sintering process.

What is claimed is: 
     
         1 . A viewing panel for an electronic device, the viewing panel comprising:
 a display window made of sapphire; and   a supporting body made of ceramic;   wherein the display window is supported by the supporting body, and the display window is integrally formed with the supporting body by sintering.   
     
     
         2 . The viewing panel of  claim 1 , wherein the display window is positioned in the center of the viewing panel, and the display window is surrounded by the supporting body. 
     
     
         3 . The viewing panel of  claim 1 , wherein the supporting body defines a through hole, and the display window is received in the through hole and coupled to an inner wall of the through hole. 
     
     
         4 . The viewing panel of  claim 1 , wherein the supporting body is positioned at one side of the display window. 
     
     
         5 . The viewing panel of  claim 1 , wherein the ceramic is aluminum oxide, zirconia, silicon nitride, or steatite porcelain. 
     
     
         6 . The viewing panel of  claim 1 , wherein the display window is made of sapphire, and the supporting body is made of ceramic powders by sintering. 
     
     
         7 . The viewing panel of  claim 1 , wherein a surface of the viewing panel is grinded and polished.
