Specific embodiment:

Below in conjunction with attached drawing, the content of the present invention will be further explained.

As depicted in figs. 1 and 2, it is of the present invention can electrically heated new line show laminated glass, can with to generate P inclined The optical projection system of vibration light realizes new line display function together.Have the function of the display (HUD) that comes back, but also tool to make laminated glass not only There is the heat insulating function of reflection infrared ray, also there is electric heating function, the present invention had both deposited on laminated glass being capable of reflected P polarization Light realizes the transparent nano film of new line display function, and infrared ray can either be reflected by being also deposited with can carry out electric add again with composite electrode The conduction of heat is low-emission coated；Specifically, it is of the present invention can electrically heated new line show that laminated glass includes interior glass Plate 11, outer glass plate 12 and the intermediate diaphragm 13 being clipped between interior glass plate 11 and outer glass plate 12；It in the present invention, will be outer Glass plate 12 is that outer glass plate-Air Interface is defined as first surface farthest away from the surface of intermediate diaphragm, most by outer glass plate 12 It is second surface close to the surface of intermediate diaphragm i.e. outer glass plate-centre diaphragm interface definition, by interior glass plate 11 in Between diaphragm surface i.e. in glass plate-centre diaphragm interface definition be third surface, by interior glass plate 11 farthest away from intermediate diaphragm Surface i.e. in glass plate-Air Interface be defined as the 4th surface；The transparent nano film 14 is deposited on the 4th surface, it is described Transparent nano film 14 includes at least one high index layer/low index layer being sequentially depositing outward from interior 11 surface of glass plate Laminated construction, the refractive index of the high refractive index layer are not less than 1.8, and the refractive index of the low-index layer is not higher than 1.5；Fig. 1 It shows and is deposited with conduction low-emission coated 15 in second surface；Fig. 2 shows be deposited with conductive Low emissivity plating on third surface Film 15.

In fig. 1 and 2, the P-polarized light 101 that optical projection system 100 generates is with 60~75 degree of incident angles described in On transparent nano film 14, first reflected light 102 of the transparent nano film 14 the reflection generation of the part P-polarized light 101 Form the main picture of the visual new line display image of human eye 200；Another part P-polarized light enters folder through the transparent nano film 14 It is propagated in layer glass, the P-polarized light propagated in laminated glass reaches the conduction low-emission coated 15 or third on second surface When conduction low-emission coated 15 on surface, reflection can partially occur and be emitted from the 4th surface refraction to generate first refractive light 103, form the secondary picture for the display image that comes back；It is secondary as more when the reflectivity of conductive low-emission coated 15 pairs of P-polarized lights is higher Obviously, to generate the ghost phenomena for the display image that comes back.

In order to eliminate issuable ghost phenomena, new line display compound heat-insulation and electric heating function is better achieved, such as Shown in Fig. 1, when second surface is deposited with conduction low-emission coated 15, arrangement is for connecting in the conduction low-emission coated 15 The first electrode 16 and second electrode 17 of external power supply (not shown) are connect, the conduction low-emission coated 15 includes from outer glass plate First medium layer, the first silver layer, second dielectric layer, the second silver layer and the third dielectric layer that 12 surfaces are sequentially depositing outward, it is described Third dielectric layer includes at least one sublayer, wherein the sublayer farthest away from outer glass plate 12 is nitride or oxynitride layer；This It is because most preferably double silverskin systems can when outer glass plate 12 deposits low-emission coated 15 on the surface of intermediate diaphragm The heat insulating function of reflection infra-red radiation is realized when realizing new line display function in conjunction with transparent nano film.
