Description
Technical field
The present invention relates to display technology field, more particularly to a kind of use EN-EMC glass is aobvious
Show device.
Background technology
The main method for increasing shield effectiveness is exactly to keep good in the gap of structure and interface
It is electrically continuous, usually take such as Li Wubin to exist《Low emissivity reinforced liquid crystal displays are designed》
(electric mechanical engineering, 2012,28 (6):8-12,16) in way：
1. each radome does plating nickel on surface treatment, and ruggedized monitor inner chamber is done at electric conductive oxidation
Reason, or coating conduction liquid, conductive paint strengthen conductive magnetic properties.
2. add shielding magnet ring at each cable gateway, reduce electromagnetic interference
3. form has the laminated glass of extension silk screen using surrounding, is taken with surrounding housing using silk screen
It is connected into the shield of closing.Add conductive rubber pad between silk screen and metal press box, and use metal pressure
Frame is compacted, and to prevent screen warpage from deforming, need to be cemented in silk screen mounting surface with copper-foil conducting electricity
On, unnecessary silk screen is wiped out, and corner radius are not less than 3mm.
Above-mentioned is the general approach of low radiation monitor, can reach anti-information leakage effect, but
Have the following disadvantages：
1. coating conduction liquid, technique of conductive paint etc. are not suitable for large-scale production；
2. the mode of magnet ring is depended merely on plus shielded at cable gateway can reduce the work of electromagnetic interference
With limited, if interface overlap joint is bad to still suffer from electromagnetic leakage；
3., because silk screen flexibility is larger, it is warpage uneven under nature, therefore silk screen and gold
It is effective electrically continuous but conductive from each other in order to ensure to add conductive rubber pad between category press box
Rubber blanket is expensive, and also needs that silk screen is bonded at into mounting surface with Copper Foil by the design in text
On, and wipe out unnecessary silk screen, these be all due to having used interlayer wire glass after, display
The unavoidable technological measure in assembling is produced, and this undoubtedly increased the complexity of Product Assembly
Degree, workman also needs that by certain training operating procedure and Attention Points could be familiar with, and increased
Cost of labor and hidden danger of quality.
4. woven wire is clipped in the middle of layer glass, in structure with the distance of liquid crystal display display surface
Cannot eliminate, not only increase the size in display thickness direction, shield glass and liquid crystal display it
Between space also there is the possibility of day laggard dust, it is often more important that, this distance is likely to result in
There is interference fringe, influence display effect.
The content of the invention
It is an object of the invention to provide a kind of display of use EN-EMC glass, for solving
Above-mentioned problem of the prior art.
A kind of display of use EN-EMC glass of the present invention, wherein, including：Press strip, EN-EMC
Glass, liquid crystal screen module, framework and back cover；The EN-EMC glass is attached to the liquid crystal screen module
On, the metal wire side of the EN-EMC glass is pressed on four metal frameworks by the press strip, real
Now good conductive overlap joint；The rear cover behind the framework, for by the liquid crystal screen module
Encapsulation.
One embodiment of the display of EN-EMC glass of the invention, wherein, the framework with
Pad blind to form complete shield by conductive fabric between the back cover.
One embodiment of the display of EN-EMC glass of the invention, wherein, conductive fabric lining
Pad can be made up of the foam of metallic fiber,
One embodiment of the display of EN-EMC glass of the invention, wherein, the EN-EMC
Glass tape metal etch net, the metal etch net is covered on a pet film, and the one side with glass is glued,
The wire netting is faced outwardly, and surrounding reserves overlap joint edge.
One embodiment of the display of EN-EMC glass of the invention, wherein, the EN-EMC
The cable interface of the display of glass includes：VGA socket jackets, shielding finger and VGA plugs
Sheath；The VGA socket jackets are provided with groove, install one week shielding finger, the screen additional in the groove
Cover and offseted on the outside of reed and VGA plug boots.
The display of EN-EMC glass of the invention, one is made by shield structure and liquid crystal display
Module, while shield effectiveness is met, significantly reduces physical dimension and weight.

Specific embodiment
It is below in conjunction with the accompanying drawings and real to make the purpose of the present invention, content and advantage clearer
Example is applied, specific embodiment of the invention is described in further detail.
Fig. 1 is upward view of the present invention using the display of EN-EMC glass；Fig. 2 is the circle of Fig. 1
Zoomed-in view at circle；Fig. 3 is overall structure of the present invention using the display of EN-EMC glass
Figure；Fig. 4 show partial sectional view of the present invention using the display of EN-EMC glass；Fig. 5
It show the front view of EN-EMC glass；Fig. 6 show the partial view of EN-EMC glass；Ginseng
Fig. 1-6 are examined, the display using EN-EMC glass includes：Press strip 1, EN-EMC glass 2, liquid
Brilliant panel module 3, framework 4 and back cover 6.
With reference to Fig. 1-6, EN-EMC glass 2 is attached on liquid crystal screen module 3, by four press strips 1
Fixed, the metal wire side 21 of the surrounding of EN-EMC glass 2 is pressed on four metal frameworks by press strip
On 4, good conductive overlap joint is realized.Metal back cover 6 is covered behind framework 4, by liquid crystal display
Module 3 is encapsulated.
Conductive fabric such as can be added filling irrigating sealant is padded with reference to Fig. 1-6, between metal framework 4 and back cover 6
Gap is forming complete shield.
Further, conductive fabric pad can be made up of the foam of metallic fiber, foam core tool
There are high resiliency and uniformity, be particularly well-suited to need the field of low closure force and minimal compression deformation quantity
Close, it is ensured that continuous complete contact between fitting surface, metallic fiber has corrosion resistant nickel coating, because
This has good electrochemistry compatibility, compared with general conductive rubber material, conductive fabric pad
Price is also less expensive.
With reference to Fig. 5 and Fig. 6, the present invention is using the display of EN-EMC glass in order to realize electromagnetism
Shielding purpose, and product cost is reduced, the present invention uses a kind of conduct of new E N-EMC glass 2
Shielding form, glass 2 is the form that net 21 is etched with single-layer metal, and metal etch net overlays on PET
On film, then the one side again with glass is glued, and wire netting is faced outwardly, surrounding size on demand
Reserve overlap joint edge.
For display cost, shield glass occupies certain weight proportion, using in the present invention
EN-EMC glass can make more than hundred yuan of cost reduction.Also, PET film rigidity is larger, flatness
It is good, good overlap joint is realized during assembling naturally, suitable width can be reserved according to product structure,
Do not exist laminated glass woven wire warpage thus and need to cut the problem of redundance.Use
The spatial shaping that this glass can also be reserved in surrounding goes out various forms of holes and is put with meeting
The needs such as button, indicator lamp are put, and woven wire does not possess this machinability.
