Title: Display device

CROSS REFERENCE TO RELATED APPLICATIONS 
     This Application claims priority of Taiwan Patent Application No. 97107313, filed on Mar. 3, 2008, the entirety of which is incorporated by reference herein. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a display device, and in particular, to a display device having the ability to receive display panels with different thicknesses, without drastically and inconveniently changing the original arranged structure. 
     2. Description of the Related Art 
     A conventional display device comprises an upper casing, a lower casing, a display panel and a shield. The shield is directly disposed on the display panel, and is fixed between the upper casing and the lower casing along with the display panel. 
     As technology advances, the display panel is becoming thinner and thinner. When the thickness of the display panel decreases, a gap is formed between the display panel and the shield. If no corresponding design or arrangement is made to fill up the gap therebetween, the interior components of the display device will not be appropriately fixed, thus resulting in a less-stable structure. Alternatively, a new casing may be fabricated to suit the new display panel, but manufacturing costs would accordingly increase. 
     BRIEF SUMMARY OF THE INVENTION 
     The invention provides a display device. The display device comprises a housing, a display panel, a shield, and an elastic member. The housing has a first frame and a second frame. The display panel, disposed in the housing, abuts the first frame. The shield, disposed in the housing, abuts the second frame. The elastic member, disposed between the display panel and the shield, comprises a plurality of supporting portions, at least one abutting portion and an elastic portion extended from the abutting portion. 
     A detailed description is given in the following embodiments with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1A  depicts an exploded view of a display device of the invention, and  FIG. 1B  depicts a partially exploded view of a portion A of the display device in  FIG. 1A . The display device  10  comprises a housing  101 , a display panel  103 , a shield  105  and a plurality of elastic members  107 , wherein the housing  101  comprises a first frame  101 A and a second frame  101 B. 
     The display panel  103 , disposed in the housing  101 , abuts the first frame  101 A. The shield  105 , also disposed in the housing  101 , abuts the second frame  101 B. A distance D is formed between the display panel  103  and the shield  105 . 
     In other words, in the embodiment, the display panel  103  is a new and improved flat panel comprising a thickness T (as shown in  FIG. 1B ). Because the thickness T of the display panel  103  is relatively thin, the distance D is formed between the display panel  103  and the shield  105 . By disposition of the elastic members  107  between the display panel  103  and the shield  105  to fill up the gap formed by the distance D, the overall structure is thus enhanced. 
       FIG. 2  depicts a schematic view of the elastic member of the invention. Referring to  FIG. 1B  and  FIG. 2 , each elastic member  107  comprises four supporting portions  107 A, two abutting portions  107 B and an elastic portion  107 C. Besides, the supporting portions  107 A, the abutting portions  107 B and the elastic portion  107 C are integrally formed as a single piece by metal. Each supporting portion  107 A comprises a connecting portion and one or more than one supporting strips. Four supporting portions  107 A alternately connect with two abutting portions  107 B. The elastic portion  107 C is horizontally extended from one of the abutting portions  107 B to form a plate with a convex S disposed thereon. 
     Referring to  FIG. 1B  again, the supporting portion  107 A of the elastic member  107  comprises a first height H 1 , and the convex S on the elastic portion  107 C comprises a second height H 2 . The first height H 1  equals to the distance D, and the first height H 1  plus the second height H 2  is substantially greater than the distance D. 
     Additionally, under the circumstance where the interior space of the housing  101  is fixed, the sum of the thickness T of the display panel  103  and the distance D of the shield  105  is also fixed. When the thickness T of the display panel  103  changes, the distance D accordingly changes. In other words, when the thickness T of the display panel  103  increases, the distance D relatively decreases. The first height Hi of the supporting portion  107 A also accordingly decreases, and vice versa. 
       FIG. 3  depicts a schematic view of the elastic member and the shield of the invention. Referring to  FIG. 1B  and  FIG. 3 , a plurality of elastic members  107  is disposed on the periphery of the shield  105  by the supporting portions  107 A (as shown in  FIG. 3 ). The abutting portions  107 B and the convex S abut the display panel, respectively. Because the first height H 1  of the supporting portions  107  equals to the distance D between the display panel  103  and the shield  105 , the elastic members  107 , disposed between the display panel  103  and the shield  105 , provide a supporting and connecting function, thus, avoiding displacement of the display panel  103  or the shield  105 . Furthermore, the convex S comprises a second height H 2 . Additionally, when the abutting portions  107 B abut the display panel  103 , the convex S is pushed downward by the display panel  103 . Therefore, an absolute shielding effect is generated as the elastic portions  107 C provide elasticity to allow a tight contact between the convex S and the display panel  103 . 
     The invention uses the disposition of the elastic members, so that the display device is able to be assembled with different types of display panels with different thicknesses. Accordingly, the main structure of the display device does not have to be redesigned, thus, saving costs, stabilizing the overall structure and improving shielding ability over conventional non-altered or non-redesigned display devices. 
     While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
