Background technology
Display device in the airborne navigational system needs intuitively, provides various information and steady operation to the pilot visually.Although display device is becoming better and approaching perfection day by day aspect the demonstration directly perceived, vivid, because display device be unable to do without the indispensable parts such as liquid crystal display and glass, therefore before equipment, all need display device is done a series of verification experimental verification.Because environment is harsher in the cabin, radiation is strong, causes display easily to be interfered, and needs radiation proof; When winter, easy ponding mist also on the display screen.
Traditional display is usually installed in the indenture of light guide plate medial surface and is fixed a shield glass in order to reach radiation-resistant effect, and light guide plate and display panel are fixed in corresponding inboard bezel locations applying and by screw.This structure setting has certain radiation-proof effect, but still can not be satisfactory under the rugged surroundings in the cabin.
Summary of the invention
The invention provides a kind of antifog radiation-proof display and job operation thereof, to avoid the impact of external electromagnetic radiation and water smoke.
The solution that provides of the present invention is as follows.
A kind of antifog radiation-proof display comprises the light guide plate, shield glass, display panel, the electronic circuit board that set gradually from outside to inside; Shield glass is mounted in the indenture of light guide plate medial surface, and light guide plate and display panel are fixed in corresponding inboard bezel locations applying and by screw; Between the inboard frame of light guide plate and display panel, fixedly be pasted with the zigzag copper reed with the suitable closure of whole inner side edge shaped as frame shape; The rear portion of described display panel and electronic circuit board are packaged in the same housing, and the frame of display panel is connected and fixed by the inboard frame of screw and described light guide plate, make the two sides of the adhesive copper reed of described zigzag be close to respectively light guide plate and display panel.
Based on above-mentioned basic scheme, the present invention also can do following optimization and limit and improve:
Above-mentioned shield glass has intermediate course, this intermediate course is set to layer of metal silk screen (perhaps also can be metal cladding), described wire gauze stretches out, its epitaxial part and is adhesively fixed with the whole inboard frame of light guide plate between the zigzag copper reed of the whole inboard frame of light guide plate and described closure.
The upper end of above-mentioned housing is provided with one or more bleeder vents.
The position fixing at light guide plate and display panel screw is provided with pad.
The present invention gives a kind of job operation of above-mentioned antifog radiation-proof display, comprises following link:
(1) the wire gauze epitaxial part with shield glass is bonded on the inboard frame of light guide plate, and the shield glass main body is fixed in the indenture of light guide plate medial surface;
(2) make adaptive band viscosity zigzag copper reed according to the frame shape of light guide plate and display panel, this with on the bonding whole inboard frame that is close to light guide plate of viscosity zigzag copper reed, is formed the closed-loop path at whole inboard frame;
(3) rear portion and the electronic circuit board with display panel is packaged in the same housing, and this housing upper end offers an organ timbering shape through hole near the display panel place;
(4) adopt screw that light guide plate and display panel are fixed, be socketed with pad on the screw, so that light guide plate and display panel are fitted in corresponding inboard bezel locations.
The present invention has the following advantages:
1, insulation, heat insulation, radiation proof, water-mist-proof are effective, and through verification experimental verification, display device can work under the rugged surroundings of cabin.
2. simple in structure, reliability is high.

The drawing reference numeral explanation:
The 1-light guide plate; The 2-display panel; 3-zigzag copper reed; The 4-air hole.
Embodiment
The present invention puts into the structure of display and machine and has gone global design, as shown in Figure 1.
At the glass of shield glass therebetween one deck silk screen or metal cladding realization shielding, copper reed is a kind of electroconductive elastic sheet structure that prevents central processing unit (being called for short CPU) Electromagnetic Interference (Electromagnetic Interference is called for short EMI).Disturb extraneous (operation that comprises nearby computers reaches the human injury) because the central processing unit operation can generate electromagnetic waves, therefore use the conductive characteristic of copper reed, can effectively disturb electromagnetic wave excessive, reach the safety examination criteria.Copper reed seals the space of two surface of contact, and the height electromagnetic shielding effect is provided.Copper reed has outstanding crushing resistance and rebound resilience, and corrosion resistance, and good broadband electromagnetical shield effectiveness is provided, and is specially adapted to panel gap and fills.
Shield glass sticks with glue with specialty and receives leaded light strip indenture one side owing to accompanying gauze screen in the middle of the shield glass, this gauze screen be bonded in light guide plate around, play shielding action.In order to strengthen shield effectiveness, be at the bonding shielding copper reed of light guide plate periphery.At first customize the adhesive copper reed of zigzag of certain size shape according to the shape of display device, the adhesive copper reed of this zigzag is added the whole inboard frame that overlays on light guide plate, cover the display panel that closes, the adhesive copper reed of zigzag is close to two faceplate panels, reinforces with screw again.The adhesive copper reed of zigzag is the equal of to have formed a copper wall by the copper reed that lengthens, and stops radiation source to the radiation of display device.
If remove the adhesive copper reed of this zigzag, then shield effectiveness is slightly poor.The remarkable advantage that zigzag compares to wide strip-like copper reed is that zigzag copper reed radiation proof surface widens increasing, and radiation-proof effect is good, and is lightweight.
The ultimate principle of electromagnetic radiation protective materiall mainly is based on electromagnetic wave when passing the anti-electromagnetic radiation material, produce wave reflection, ripple absorbs and the Multi reflection of electromagnetic wave in material, cause the electromagnetic wave energy decay, common radiation proof material and the contrast of zigzag copper reed radiation proof material attenuation degree are as shown in Figure 2.
Shell is to seal fully traditionally, enters to prevent moisture; But actual conditions are to be consistent with external environment, just be unlikely to bear water mist, therefore perforate ventilation maintenance temperature is consistent in design in the present invention, be that shell upper is near the position of zigzag copper reed, offer two or more cylindrical holes along same line spread better, be used for temperature in the balance cabin and display because of work heating rising temperature, when the rising of display device temperature, and temperature is on the low side in the cabin, will cause temperature contrast and forms mist at display device screen.
Mounting means is followed successively by light guide plate (the control button can be set on the housing of light guide plate), shield glass (the middle gauze screen of installing), display pannel, electronic circuit board from outside to inside.(display pannel and electronic circuit board at first encapsulate and are fixed in the housing).
