Example 1
As shown in fig. 2, an embodiment of the present invention provides a shielding panel 20 applied to a display module, where the shielding panel 20 includes: a first transparent substrate 21, a second transparent substrate 22, a wire mesh; the wire net includes: a wire mesh first portion 230 between the first transparent substrate 21 and the second transparent substrate 22 disposed opposite to each other, and a wire mesh protruding portion 231 around the outside of an area where the first transparent substrate 21 and the second transparent substrate 22 are opposite to each other; the first transparent substrate 21 is close to the display module to be attached; an annular protrusion 221 is formed on a side of the second transparent substrate 22 away from the first transparent substrate 21.
It should be noted that the first transparent substrate 21, the second transparent substrate 22 and the wire mesh located therebetween can be processed by a special process (specifically, a bonding process) to form the wire-mesh-sandwiched electromagnetic shielding glass in combination.
The specific structure of the second transparent substrate 22 is further illustrated in fig. 3 and 4.
Since the first transparent substrate 21 is close to the display module to be bonded, and one side of the second transparent substrate 22 disposed opposite to the first transparent substrate is disposed at a corresponding position on the metal outer frame to be mounted, the protrusion 221 is disposed on one side of the second transparent substrate 22 away from the first transparent substrate 21, and in order to implement the sealing mounting, the shape of the protrusion 221 is specifically an annular shape as shown in fig. 3.
Here, considering that when the shielding panel 20 is applied to a display module, a display window of a ruggedized display device (e.g., ruggedized computer) is generally rectangular, a corresponding metal frame is also rectangular, and the second transparent substrate 22 needs to be mounted on the metal frame, the overall ring shape of the protrusion 221 is also a matrix ring, so as to simplify the processing process of the metal frame structure.
The term "rectangular ring" refers to a portion defined between two rectangles having respective parallel four sides and having coincident centers of symmetry, and is called a "rectangular ring".
The specific height, width and other dimensions of the protrusion 221 formed on the second transparent substrate 22 are related to factors such as an assembly structure, a selection of a sealing structure sleeved at the corresponding mounting position of the protrusion 221 and the metal outer frame during mounting, and a specific application environment of the assembled reinforcement product, and should be selected according to the actual application of the product.
Based on this, according to the shielding panel provided by the embodiment of the present invention, the annular protrusion 221 is added on the side where the shielding panel is installed with the metal outer frame, when the shielding panel is assembled with the metal outer frame, the protrusion 221 is placed in the groove of the corresponding installation position on the metal outer frame, and the sealing structure is added between the groove and the protrusion 221, so that the sealing and the waterproofing of the shielding panel after being installed on the metal outer frame can be realized by using the concave-convex matching of the protrusion 221 and the groove on the metal outer frame, and the practicability is strong; because the sealing and waterproofing are realized without special waterproof double-sided adhesive with extremely strong viscosity, the shielding panel and the metal outer frame can be bonded by the double-sided adhesive (such as pressure-sensitive adhesive) with ordinary viscosity, so that the product can be conveniently detached during subsequent maintenance and replacement, and the material cost can be reduced by adopting the ordinary double-sided adhesive.
On the basis of the above, in order to facilitate the formation of the structure of the protrusions 221 on the second transparent substrate 22, the second transparent substrate 22 is made of an organic transparent material, or both the second transparent substrate 22 and the first transparent substrate 21 are made of an organic transparent material, so that the second transparent substrate 22 with the structure of the protrusions 221 can be prepared by a simple conventional technical means such as injection molding.
The organic transparent material specifically includes: at least one of polyethylene terephthalate (PET), Polycarbonate (PC), and polymethyl methacrylate (PMMA).
Further, since the overall height of the protrusion 221 formed on the second transparent substrate 22 is greater than the thickness of the second transparent substrate 22 in other areas, the shrinkage rate of the protrusion 221 during processing is greater than the shrinkage rate of the other areas of the second transparent substrate 22, so that the shape of the prepared protrusion 221 is smaller than the set shape, and in order to avoid such processing defects, as shown in fig. 4, the protrusion 221 has a hollow structure (the hollow structure is shown by a mark a in the drawing), so as to facilitate processing and injection molding.
Example 2
An embodiment of the present invention provides a reinforced display device, including: a metal outer frame 30 and a display module; as shown in fig. 5, the metal outer frame 30 includes: four side walls 31 and a support plate 32 connecting the four side walls which are connected in sequence; an opening area 320 for displaying is opened on the supporting plate 32; the display module (not shown) is disposed in the installation space enclosed by the four sidewalls 31.
As shown in fig. 6, the ruggedized display device further includes: the shield panel 20 (the reference numeral is not shown in the figure) in embodiment 1 described above; a double-sided tape 40 for bonding the shield panel 20 and the support plate 32; a seal structure 41; wherein, one side of backup pad 32 orientation display module assembly includes: a first end face 32a and a second end face 32b protruding from the first end face 32a and connected to the side wall 31; the second transparent substrate 22 is disposed above the first end surface 32a, and the first end surface 32a is provided with a groove 321 corresponding to the protrusion 221 (the reference numeral is not shown in the drawings, please refer to the previous drawings); the double-sided tape 40 is disposed between the second transparent substrate 22 and the first end surface 32a, and is used for assisting in fixing the shielding panel 20; a gap is formed between the protrusion 221 and the groove 321, and the sealing structure 41 is disposed at the gap; the wire-net protruding portion 231 is placed above the second end face 32 b.
The opening region 320 opened in the first support plate 32 for display is a display window of the reinforced display device. The display module is mounted above the shielding panel 20 shown in the figure, and the displayed image is displayed through the shielding panel 20 below.
Secondly, a groove 321 corresponding to the protrusion 221 is processed on the first end face 32a of the support plate 32 for placing the shielding panel 20, and a sealing structure is added between the groove 321 and the protrusion 221, and the sealing structure 41 pressed into the groove 321 by the protrusion 221 is used for realizing the sealing and water proofing after the shielding panel 20 is installed on the metal outer frame 30.
Because the sealing and waterproofing of the shielding panel 20 are not required to be realized by special waterproof double-sided adhesive with extremely strong viscosity, and the double-sided adhesive 40 only serves to realize auxiliary positioning, the shielding panel 20 and the metal outer frame 30 can be bonded by the double-sided adhesive 40 with ordinary viscosity (such as pressure-sensitive adhesive), so that the product can be conveniently detached during subsequent maintenance and replacement, and the material cost can be reduced by adopting the ordinary double-sided adhesive.
Third, the double-sided adhesive tape 40 may be disposed on the first end face 32a and surround the protrusion 221; it is also possible to provide only the projection 221 close to the inner side of the side wall 31 of the metal bezel as shown in fig. 6, thereby improving the convenience of the above-described removal of the reinforced display device.
Fourth, the sealing structure 41 may be a sealing sleeve as shown in fig. 6, that is, the sealing sleeve is sleeved on the protrusion 221, and the protrusion periphery and the top end of the protrusion 221 away from the second transparent substrate 22 are both wrapped.
Alternatively, the sealing structure 41 may be a sealing ring, which is only sleeved around the protrusion of the protrusion 221.
Alternatively, the sealing structure 41 may be a sealing gasket disposed only between the top end of the protrusion 221 away from the second transparent substrate 22 and the groove 321.
The specific shape of the sealing structure 41 can be flexibly selected according to the structural size of the protrusion 221 and the specific performance requirement of sealing and waterproofing, which is not limited in the embodiment of the present invention.
The sealing structure 41 may be made of silica gel with a compact structure, which can block water vapor from permeating through and has a buffering effect.
Further, another difficulty encountered in the prior art in reinforcing electromagnetic shielding in computer product designs is poor window shielding, i.e., poor electrical conduction due to breakage of the shielding glass mesh.
Referring specifically to fig. 1, the dimension of the wire mesh 13 exceeding the shielding glass is called skirt, and the conventional electromagnetic compatibility processing method of the display module is to connect the wire mesh skirt of the shielding glass with a metal front frame (i.e., a chassis) to form a shielding cavity. The plane of fixed silk screen shirt rim is higher than the silk screen, and need pass corresponding mounted position department on the casing with the silk screen shirt rim through screw pass clamp plate 42, screw hole 43 when the installation, can produce certain extrusion to the silk screen shirt rim, causes the damage of silk screen easily, produces electrically conductive bad, influences electromagnetic shield effect.
Based on this, in order to further solve the easy breakage phenomenon during the assembly of the wire mesh and protect the protruding skirt portion of the wire mesh, in a preferred embodiment of the present invention, referring to fig. 6, the reinforced display device further includes: a conductive cloth 44 wrapping the wire mesh protruding portion 231; a conductive adhesive 45 disposed between the second end face 32b and the conductive cloth 44; a pressing plate 42 provided at least at opposite sides of the shielding panel 20; the fasteners securing the platen 42 to the second end face 32b can be removed.
Wherein, the pressure plate 42 specifically includes: a first plate 421 engaged with one edge of the first transparent substrate 21 away from the second transparent substrate 22; a second plate surface 422 disposed above the second end surface 32 b; a connecting portion 423 connecting the first plate 421 and the second plate 422; as shown in fig. 7, a portion of the second plate 422 is covered on the conductive cloth (illustrated as a black area in the figure), and a portion of the second plate 422 not covered on the conductive cloth is detachably fixed on the second end surface by a fastener.
Here, the conductive cloth 44 is used to wrap the wire-net protruding portion 231, i.e., to protect the wire-net skirt. Since the protruding portion 231 of the metal mesh wrapped by the conductive cloth 44 is fixed to the metal outer frame 30 by the conductive adhesive 45 (i.e., the double-sided adhesive tape with conductivity), the fastening member (e.g., a screw) for fixing the pressing plate need not pass through the protruding portion 231 of the metal mesh below, but only pass through the portion of the second plate 422 not covered by the conductive cloth to fasten the second plate 422 to the metal outer frame 30, thereby avoiding the damage in the process of assembling the metal mesh.
For example, referring to fig. 7, the fastening members may be disposed at both ends of the second plate 422 not covering the conductive cloth, that is, both ends of the protruding portion of the wire net are locked, thereby pressing and wrapping the conductive cloth and fixing the wire net.
In fig. 7, only the screw holes 43 for fixing the screws formed at both ends of the conductive cloth are not covered on the second plate 422 when the fasteners are screws.
Here, the height of the second end surface 32b protruding from the first end surface 32a may be slightly less than the thickness of the second transparent substrate 22, and the wire mesh protruding portion 231 is flatly placed above the second end surface 32b by adjusting the thicknesses of the conductive cloth 44 and the conductive paste 45.
In addition to the above, referring to fig. 6, the reinforced display device further includes: and a buffer sheet 46 provided between the first plate 421 of the pressing plate and the first transparent substrate 21.
The buffer sheet 46 can be made of EVA (ethylene vinyl acetate) foam material, for example, to improve the locking and fixing effect between the first board 421 and the contact surface of the first transparent substrate 21.
The specific installation process of the reinforced display device involving the metal bezel 30 and the shielding panel 20 is as follows:
through the processing of a special process, the second transparent substrate 22 with the annular protrusion 221 structure, the first transparent substrate 21 arranged oppositely and the wire mesh are combined into the shielding panel 20, a groove-shaped structure matched with the annular protrusion 221, namely a groove 321, is processed on the first end face 32a on the supporting plate 32 of the metal outer frame 30 in advance, sealing silica gel is put in the groove, and a common double-sided adhesive 40 is adhered to the surface of the shielding panel 20, which is in contact with the metal outer frame 30. The shielding panel 20 is placed on the first end face 32a of the supporting plate 32, and the protrusion 221 structure is pressed into the sealing structure 41, so that sealing and water proofing are realized. The shielding panel 20 as a whole is assisted in positioning by a common double-sided adhesive tape 40. The conductive cloth 44 is wrapped on the wire mesh protruding part 231 beyond the glass edge, and is adhered to the metal frame through the conductive adhesive 45 to realize the conduction with the shielding panel 20. A buffer sheet 46 made of EVA foam is added on the surface of the first transparent substrate 21 in contact with the first plate 421 of the pressing plate 42, the second plate 422 is used to press and wrap the conductive cloth 44 and fix the wire mesh, and the other surface (i.e. the first plate 421) is pressed on the buffer sheet 46 and fixed on the first end surface 32a of the supporting plate 32 of the metal frame 30 by locking screws to complete the installation.
