Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a technology of packaging, and more particularly to a packaging device for a display module or the like. 
       BACKGROUND OF THE INVENTION 
       [0002]    Currently, the existing packaging protection for LED display module and other electronic devices having a liquid crystal display screen is simply as follow: deploying a static-proof film over a surface of the display panel, then disposing the display panel into a static-proof bag, and then the whole is put into a carton box. The static-proof film is not adhesive, and it needs additional adhesive tap or other material to properly attach it to the module. In an addition, once the module needs to be removed from the package, a reverse process is required. It is really inconvenient. On the other hand, both of the static-proof film and the static-proof bag are requested when packaging the LED display module. Specially, those packaging material are utilized only once and then throw away after the display module is removed from the box. This is a waste and inevitably increases the manufacturing cost. In addition, the material used for static-proof is not environmental-friendly.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0026]    Referring to  FIG. 1 , a cross sectional view of a packaging device made in accordance with a first embodiment of the present invention is shown. According to the first embodiment, the packaging device includes a static-proof film  10 , a Velcro hooks patch  20  and a Velcro loops patch  30 . 
         [0027]    The static-proof film  10  is used to shield static. The film  10  can be coated with a layer of static-proof material or directly made from a material blended with static-proof material. 
         [0028]    According to a preferred embodiment, the static-proof film  10  includes a PE (polyethylene) film and a static-proof EPE (expandable polyethylene) film deployed over the PE film. The PE film and the EPE film are attached together by a heat press so as to empower the static-proof film  10  with elastic property, while it is gentle to touch. 
         [0029]    Alternatively, in other preferable embodiment, the static-proof film  10  can be made from a compound of polyanilime resin by blending with 6-10 percent by weight of polyanilime into resin. With the static-proof property of the polyanilime, the static-proof film  10  can be equipped with static-proof property. 
         [0030]    The Velcro hooks patch  20  and the Velcro loops patch are symmetrically arranged on borders of the static-proof film  10 . In addition, the Velcro hooks patch  20  and the Velcro loops patch  30  are arranged on a top surface of the static-proof film  10 . In the current embodiment, the Velcro hooks patch  20  is arranged on a bottom surface of the static-proof film  10 , while the Velcro loops patch  30  is arranged on a top surface of the static-proof film  10 . In other preferred embodiment, the location of both the Velcro hooks patch  20  and the Velcro loops patch  30  can exchange with each other. Alternatively, the Velcro hooks patch  20  and the Velcro loops patch  30  can be arranged on both the top and bottom surfaces of the static-proof film  10 . 
         [0031]      FIG. 2  is a top view illustrating the packaging device before it is wrapped over an electronic device. Before the electronic device  40  is wrapped by the packaging device of the present invention, the static-proof film  10  is flattened over a flat surface, and with the electronic device  40  disposed on a center thereof. For the example, the electronic device can be a LED module, a liquid crystal display module or a liquid crystal display panel. 
         [0032]    The overall length of the static-proof film  10  is longer than the length of the electronic device  40 , preferable for two times. The width of the static-proof film  10  is larger. By this arrangement, the static-proof film  10  can comply cover the electronic device  40  in full. 
         [0033]    From the disclosure of  FIG. 2 , the number of the Velcro hooks patch  20  and the Velcro loops patch  30  can be multiple. Preferably, the Velcro hooks patch  20  and the Velcro loops patch  30  are symmetrically arranged. 
         [0034]    Referring to  FIG. 3 , a side elevation view showing how the packaging device is used to wrap up the electronic device is disclosed. Once the electronic device  40  is disposed on the center of the static-proof film  10 , the static-proof film  10  can then be folded over the top of the electronic device  40  in a way that both the Velcro hooks patch  20  and the Velcro loops patch  30  are overlapped and then they are engaged with each other with a firm press with hand. By this arrangement, the electronic device  40  is completely packed with the packaging device provided by the present invention. In a preferred embodiment, since the static-proof film  10  is expandable, as a result, the static-proof film  10  can tightly wrap over the electronic device  40 . In generally, the glass substrate of the electronic device  40  is placed on the center of the static-proof film  10 . 
         [0035]      FIG. 4  is a cross sectional view of a packaging device made in accordance with a second embodiment of the present invention. In the preferred embodiment, the packaging device includes a static-proof film  110 , a Velcro hooks patch  200 , and a Velcro loops patch  300 . The difference between the first and second embodiments is that the static-proof film  110  further includes a first static-proof film  111 , and a second static-proof film  113 , and a layer of sponge  112 . The first and second static-proof films  111 ,  113  are sealingly integrated together so as to form an air-tight compartment (not labeled). The sponge layer  112  is evenly deployed over the sealed compartment to provide a buffer. In the preferred embodiment, the material used to make both the static-proof film  10  in the first embodiment, and the static-proof films  111 ,  113  in the second embodiment are same. Both the static-proof films  111 ,  113  are made from PE film, and an EPE film deployed over the PE film with heat press. 
         [0036]      FIG. 5  is a cross sectional view of a packaging device made in accordance with a third embodiment of the present invention. In the preferred embodiment, the packaging device includes a static-proof film  120 , a Velcro hooks patch  200 , and a Velcro loops patch  300 . The difference between the first and third embodiments is that the static-proof film  120  further includes a first static-proof film  121 , and an elastic film  123 , and a layer of sponge  122 . The static-proof films  121  and the elastic film  123  are sealingly integrated together so as to form an air-tight compartment (not labeled). The sponge layer  122  is evenly deployed over the sealed compartment to provide a buffer. In the preferred embodiment, the material used to make both the static-proof film  10  in the first embodiment, and the static-proof films  121  in the third embodiment are same. Both the static-proof films  121  are made from PE film and an EPE film deployed over the PE film with heat press. The elastic film  123  has elastic property such as a PE film. 
         [0037]    In the second and third embodiment of the present invention, a layer of sponge is evenly deployed over the sealed compartment so as to provide an impact-absorb ion. This is an upgrade as compared from the first embodiment. Tn addition, in the above described embodiment, all the static-proof films are preferred to have elastic property and are stretchable. By this provision, the electronic device can be wrapped in perfect fashion. 
         [0038]    By applying the Velcro hooks patch and the Velcro loops patch over the static-proof film, the static-proof film can be functioned as both a protective film, and a packaging bag. As a result, the protective film and the packaging bag can be integrated together. It is readily and conveniently to use, thereby expediting the packing process and no time is lost during packing. Since the packaging device made according to the present invention can be repeatedly used, not only is it environment friendly, but also it can reduce the waste of resource so as to reduce the manufacturing cost. 
         [0039]    Embodiments of the present invention have been described, but not intending to impose any unduly constraint to the appended claims. Any modification of equivalent structure or equivalent process made according to the disclosure and drawings of the present invention, or any application thereof; directly or indirectly, to other related fields of technique, is considered encompassed in the scope of protection defined by the clams of the present invention.
