Description
DISPLAY PANEL ASSEMBLY AND METHOD FOR MAKING THE SAME
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority of United State Patent Provisional Application No. 61/409134, filed on November 2, 2010.
BACKGROUND
1. Field
The present technology relates to a display panel assembly and a method for making the same, more particularly to a display panel assembly having a metal film unit disposed between and bonded to a glass panel and a plastic frame.
2. Description of the related art
U.S. Patent Application Publication No. US 2011/0049139 discloses a device housing (or a display panel assembly) for an electronic device, s uch as a mobile phone. The device housing includes a glass plate and a plastic frame injection molded over a peripheral edge of the glass plate. Since the plastic frame is normally made from a plastic material that has a low bonding strength when injection molded over the glass plate, the peripheral edge of the glass plate is roughened before the injection molding so as to enhance the bonding strength between the plastic frame and the glass plate. However, since the surface area of the peripheral edge is relatively small, bonding enhancement by edge
roughening is rather limited.
The current trend is toward thinner mobile phones. Hence, it is desirable to reduce the thickness of the glass plate. Conventional glass plates normally have a thickness greater than 0.9mm for avoiding warping of the glassplate. Inaddition, the thinner the glass plate, the lower the mechanical strength of the glass plate will be, which can easily result in breaking of the glass plate during the manufacturing process of the device housing.
SUMMARY
With the present technology, a display panel assembly that attempts to not exhibit or present the aforesaid drawbacks associated with the prior art is presented.
The present technology also provides
a method for making a display panel assembly.
According to one aspect of the present invention, there is provided a display panel assembly that comprises: a glass panel having a peripheral edge; an adhesive; a metal film unit attached adhesively to the peripheral edge of the glass panel through the adhesive; and a plastic frame disposed along the peripheral edge of the glass panel and molded over the metal film unit and the peripheral edge of the glass panel.
According to another aspect of the present
invention, there is provided a method for making a display panel assembly. The method comprises: attaching adhesively a metal film unit to a peripheral edge of a glass panel through an adhesive; and forming a plastic frame by molding a plastic material over the peripheral edge of the glass panel and the metal film unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Before the present invention is described in greater detail with reference to the accompanying
preferred embodiments, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.
Figs. 1 to 3 illustrate the first preferred embodiment of a display panel assembly for an electronic device, such as a mobile phone, according to the present invention. The display panel assembly includes: a glass panel 2 having a peripheral edge 21; an adhesive 3; a metal film unit 4 attached adhesively to the peripheral edge 21 of the glass panel 2 through the adhesive 3; and a plastic frame 5 disposed along the peripheral edge 21 of the glass panel 2 and molded over the metal film unit 4 and the peripheral edge 21 of the glass panel 2.
In this embodiment, the glass panel 2 preferably has a thickness greater than 0.6mm and less than 1mm, and further has front and back surfaces 22, 23 and a peripheral side face 24 extending from the front surface 22 to the back surface 23. The front and back surfaces 22, 23 of the glass panel 2 are parallel to each other. The peripheral side face 24 and the back surface 23 of the glass panel 2 cooperatively form an acute angle a ranging preferably from 30 to 75 degrees so that the peripheral side face 24 of the glass panel 2 has a perimeter that is gradually enlarged from the front surface 22 to the back surface 23 of the glass panel 2.
The metal film unit 4 is adhesively attached to the peripheral side face 24 and the back surface 23 of the glass panel 2 at the peripheral edge 21 of the glass panel 2.
In this embodiment, the metal film unit 4 includes a single piece of a loop -shaped rectangular metal film strip 41 surrounding the peripheral edge 21 of the glass panel 2.
The plastic frame 5 is preferably made from a plastic material, such as polycarbonate.
Fig. 4 illustrates the second preferred embodiment of the display panel assembly according to the present invention. The second preferred embodiment differs from the previous embodiment in that the metal film unit 4 includes a plurality of straight metal film strips 42 displaced from each other and disposed around the peripheral edge 21 of the glass panel 2.
In this embodiment, the peripheral edge 21 of the glass panel 2 is substantially rectangular in shape. The straight metal film strips 42 are disposed at four sides of the peripheral edge 21 of the glass panel 2, respectively.
Figs, 5A to 5C illustrate consecutive steps of the preferred embodiment of a method for making the display panel assembly according to the present invention. The method includes attaching adhesively
a metal film unit 4 to a peripheral edge 21 of a glass panel 2 through an adhesive 3 (see Figs. 5A and 5B) , followed by placing the glass panel 2 together with the metal film unit 4 in a mold 6 and forming a plastic frame 5 by injection molding a plastic material over the peripheral edge 21 of the glass panel 2 and the metal film unit 4 (see Fig. 5C) . The display panel assembly thus formed passed a drop test using 133 grams of an iron ball for the glass panel having a thickness ranging from 0.7 mm t o 0.9 mm and a size of 60 mm x 45mm. The drop test was conducted by dropping the iron ball from a height of 100cm onto the glass panel 2 of the glass panel assembly.
Since the bonding strength provided by the adhesive 3 between the metal film unit 4 and the peripheral edge 21 of the glass panel 2 and the bonding strength between the plastic frame 5 and the metal film unit 4 are each greater than that between the plastic frame 5 and the peripheral edge 21 of the glass panel 2, the binding between the plastic frame 5 and the glass panel 2 of the display panel assembly can be enhanced.
The bonding of the metal film unit 4 to the peripheral edge 21 of the glass panel 2 not only enhances the binding between the plastic frame 5 and the glass panel 2 but also permits reduction of the thickness of the glass panel 2 to 0.7 mm without causing
breaking and warping of the glass panel 2, thereby alleviating the drawbacks as encountered in the prior art during manufacturing.
While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
All elements, parts and steps described herein are preferably included. It is to be understood that any of these elements, parts and steps may be replaced by other elements, parts and steps or deleted altogether as will be obvious to those skilled in the art.
