Specific embodiment：

Present disclosure is described further below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, of the present invention electrically heated can new line shows laminated glass, can be inclined with generation P The optical projection system of light of shaking realizes together new line display function.In order that laminated glass had both had to come back shows (HUD) function, have again There is the ultrared heat insulating function of reflection, also with electric heating function, the present invention had both been deposited on laminated glass being capable of reflected P polarization Light realizes the transparent nano film of new line display function, also deposition have can either reflect infrared ray again can with composite electrode carry out electricity add Hot is conductive low-emission coated；Specifically, of the present invention electrically heated can new line shows that laminated glass includes interior glass Plate 11, outer glass plate 12 and the middle diaphragm 13 being clipped between interior glass plate 11 and outer glass plate 12；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 middle diaphragm, by outer glass plate 12 most It is second surface near the surface of centre diaphragm i.e. outer glass plate-centre diaphragm interface definition, by interior glass plate 11 near in Between diaphragm surface i.e. in glass plate-centre diaphragm interface definition be the 3rd surface, by interior glass plate 11 farthest away from middle 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 outwards sequentially depositing from the surface of interior glass plate 11 Laminated construction, the refractive index of the high refractive index layer is not less than 1.8, and the refractive index of the low-index layer is not higher than 1.5；Fig. 1 Show and have conductive low-emission coated 15 in second surface deposition；Fig. 2 shows and have conductive Low emissivity to plate in the 3rd surface deposition Film 15.

In fig. 1 and 2, the P polarization light 101 that optical projection system 100 is produced is with 60～75 degree of incident angles to described On transparent nano film 14, the first reflected light 102 of the reflection generation of 14 pairs of parts of transparent nano film P polarization light 101 Form the main picture of the visual new line display image of human eye 200；Transparent nano film 14 described in another part P polarization light transmission enters folder Propagate in layer glass, the P polarization light propagated in laminated glass reaches conductive low-emission coated 15 or the 3rd on second surface On surface conductive low-emission coated 15 when, partly can occur reflection and from the 4th surface refraction outgoing produce first refractive light 103, form the pair picture of new line display image；It is secondary as more when the reflectivity of the low-emission coated 15 pairs of P polarization light of conduction is higher Substantially, so as to producing the ghost phenomena of new line display image.

In order to eliminate issuable ghost phenomena, new line is better achieved and shows compound heat-insulation and electric heating function, such as Shown in Fig. 1, when second surface deposition has conductive low-emission coated 15, arrange for connecting in the conduction low-emission coated 15 The first electrode 16 and second electrode 17 of external power source (not shown) are connect, the conduction low-emission coated 15 is included from outer glass plate First medium layer, the first silver layer, second dielectric layer, the second silver layer and the 3rd dielectric layer that 12 surfaces are outwards sequentially depositing, it is described 3rd 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 that most preferably double silverskin systems can when outer glass plate 12 deposits low-emission coated 15 near on the surface of middle diaphragm The heat insulating function of infrared reflecting is realized when realizing new line display function with reference to transparent nano film.
