The technical scheme that its technical matters that solves the utility model adopts is: comprise shield glass and display panel, shield glass is arranged on the display panel, also comprises water resistance gasket, conducting foam, flat; The back side, viewing area of display panel is provided with glass installation groove, is provided with the ring-type padding-installing slot of perforation around the bottom of glass installation groove, and water resistance gasket is arranged in the padding-installing slot, and shield glass is placed on glass installation groove inner waterproofing liner top; Flat is arranged on the top of shield glass and display panel intersection, and flat is fixed on the display panel, thereby is fixed on shield glass on the display panel together; Be provided with conducting foam between flat and the display panel, the conducting foam position is in the outside of glass installation groove, and conducting foam is fixed on the display panel.
Shield glass is to be made of two blocks of organic glass or unorganic glass therebetween layer of metal silk screen, and wire gauze is bigger than the size of shield glass; Shield glass is placed on glass installation groove inner waterproofing liner top; The outer wire gauze of reserving of shield glass is smoothed out with the fingers the flat conducting foam top that rides over, and between flat and conducting foam, flat is fixed on the display panel, thereby the wire gauze of shield glass and reservation is fixed on the display panel together.
Wire gauze is than the monolateral big 10～15mm of shield glass size.
With screw flat is fixed on the display panel.
The flat material is stainless steel or cold-rolled steel; Flat can be fixed on the top of shield glass and display panel intersection for a whole frame, perhaps can be spliced by several; Flat thickness is 1～1.5mm.
Around the bottom of glass installation groove, be provided with the rectangular gasket mounting groove of perforation.
Water resistance gasket is bonded in the padding-installing slot; The water resistance gasket material is a silicon rubber, and color is black or white, and its hardness is 30～40 shore hardnesses; The cross sectional shape of water resistance gasket can be rectangle, D type or O type; The whole ring texture of water resistance gasket for sealing.
Conducting foam is bonded on the display panel; The conducting foam cross sectional shape is a rectangle, is with pressure-sensitive gum, has low-down surface contacted resistance.
The display panel of a kind of electromagnetic screen of the present utility model, waterproof sealing is used to have the equipment of display window, compares with prior art, has the following advantages:
1, the water resistance gasket material is a silicon rubber, and silicon rubber is very low with respect to conducting resinl (mud) cost, does not need to wait for the time of curing, greatly reduces material and installation cost;
2, the water resistance gasket material is a silicon rubber, and silicon rubber has certain elasticity, and glass is played certain buffer action, particularly unorganic glass is played the certain protection effect, has improved safety in utilization;
3, this version had both guaranteed advantages of favorable electromagnetic shielding effect, had satisfied function moistureproof, waterproof again, had played the effect of double seal;
4, this structure adopts screw to be connected and fixed, and for convenience detach and installation has improved maintainability and reusability; Thereby, have good value for applications.
