Specific embodiment
The core of the utility model is to provide a kind of electromagnetic shielding display screen, can effectively shield electromagnetic wave, reduce electricity
Magnetic wave is influenced on caused by display driving.
In order to make those skilled in the art be best understood from the technical solution of the utility model, below in conjunction with attached drawing and tool
Explanation is described in detail in the embodiment of body, electromagnetic shielding display screen and display equipment to the utility model.
It as shown in Figure 1A, is the structural schematic diagram of display screen in the prior art, Figure 1B is electromagnetism provided by the utility model
The structural schematic diagram of display screen is shielded, Fig. 1 C is the side view of part A in Figure 1B；Electromagnetic shielding display provided by the utility model
Screen includes display driving 1, and the surface covering setting shielding piece 2 of display driving 1, shielding piece 2 is conductor, can be conductive；Shield piece 2
Insulation strip 3 is set between display driving 1, namely piece 2 and display 1 mutually insulated of driving will be shielded by insulation strip 3；Insulation
Display driving 1 is completely covered item 3 namely the size of insulation strip 3 should be slightly bigger than display driving 1, to guarantee display driving 1 and screen
Cover the insulation effect between piece 2.
As shown in Fig. 2, being insulation strip 3, the structural schematic diagram for shielding piece 2,4 relative position of insulating trip；Fig. 3 A and Fig. 3 B points
It Wei not insulation strip 3, shielding piece 2, the front view interconnected of insulating trip 4 and side view.The size for shielding piece 2 is greater than insulation strip 3,
The exposed parts of insulation strip 3 are contacted with the exposed pin 51 on flexible circuit board 5, and flexible circuit board FPC is bundled in TFT bottom sheet glass
On glass；Exposed pin 51 on flexible circuit board 5 is equivalent to ground wire, forms electrostatic after shielding piece 2 is connect with exposed pin 51
Shield, the effect of electrostatic shielding body are to terminate electric field on the metal surface of shield, and charge is transferred into ground.
Shielding piece 2 is formed by impedance discontinuity at the interface of shield surface and air, shields when electromagnetic wave reaches
When covering the surface of piece 2, reflection is generated to incidence wave, makes most of reflections of electromagnetic wave to the external world；And this reflection does not require to shield
The thickness of body material is covered, as long as impedance discontinuity at interface.The electromagnetic wave of non-shielded body surface reflection enters shielding
In piece 2, constantly decay during shielding and being propagated in piece 2；In communication process unbated dump energy propagate to it is another
The surface of insulation strip 3 is arranged in surface, namely shielding piece 2, encounters the discontinuous interface of metal-air again, can be formed again anti-
It penetrates, is reflected back inside shielding piece 2 and continues to decay；Electromagnetic wave so recycles, and constantly back and forth follows between two surfaces of shielding piece 2
Ring forms multiple reflections, is gradually reflected and is absorbed by shielding piece 2, and extraneous electromagnetic wave is difficult to interfere display driving 1,
It farthest reduces on influence caused by display driving, guarantees that display is normal.
On the basis of above scheme, the shielding piece 2 of the utility model is flaky, and laminar shielding piece 2 can occur
Bending deformation can change the shape of itself with the deformation of flexible circuit board 5.
In order to further increase the deformability of shielding piece 2, bending hole 21 is opened up on shielding piece 2, bending hole 21 is located at
The lower section of piece 2 and display 1 contact position of driving is shielded, and bending hole 21 is strip, shielding piece 2 can be with flexible circuit board
5 turn down bending in the lower section of display driving 1.The shape and specific structure in the bending hole 21 being arranged on shielding piece 2 can be according to reality
Situation makes corresponding setting, and this is no longer going to repeat them for the utility model, and form is specifically arranged in these should all be practical by this
Novel protection.
The surface covering setting insulating trip 4 opposite with display driving 1 of piece 2 is shielded, insulating trip 4 covers completely by piece 2 is shielded
Lid namely insulating trip 4 at least should be equal sized with shielding piece 2, also may be slightly larger than the size of insulating trip 4, preferably by insulating trip 4
Identical chamfered shape is set with shielding piece 2, in the surface covering setting insulating trip 4 of shielding piece 2, can avoid shielding piece 2 and its
He generates conductive connection at structure, and processing is facilitated to assemble, and the shield effectiveness to shielding piece 2 is avoided to interfere.
Further, in the outer surface coating conducting resinl of shielding piece 2, conducting resinl is covered on the upper and lower surface of shielding piece 2, leads to
