The specific implementation mode is as follows:
to explain the technical content, the achieved objects and the effects of the present invention in detail, the present invention will be further explained with reference to the accompanying drawings and embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the present invention, the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. These terms are primarily intended to better describe the invention and its embodiments, and are not intended to limit the indicated devices, elements or components to a particular orientation, and therefore should not be construed as limiting the invention.
As shown in fig. 1, the utility model provides an on-vehicle glass projection system, include side window glass and fix the projection arrangement 8 in the vehicle inside, a serial communication port, side window glass is light control glass, including first light-passing board 1, first tie coat 2, second tie coat 4 and second light-passing board 7 and range upon range of light control membrane 5 and the demonstration bearer layer 3 between first tie coat 2 and second tie coat 4, show the bearer layer 3 and be located one side near the vehicle inside, as the demonstration bearer layer of projection content, projection arrangement 8's throw ratio is less than 1.4, works as when projection arrangement 8 starts the projection, side window glass's light control function starts and makes side window glass's whole transmissivity reduce.
When the projector is projected on the conventional glass, the human eyes have better visual experience, the lumen of the projector in the projection device 8 is required to reach more than 2000, and the projector meeting the requirement usually has a large size, is difficult to mount on a vehicle, and cannot well solve the heat dissipation problem caused by heat generation. Use the utility model discloses an on-vehicle glass projection system has added membrane 5 of adjusting luminance and demonstration bearer layer 3 in side window glass, has improved the effect of projection image, has reduced the requirement to projection arrangement 8 when reaching equal visual effect to can use the projector of less size and lumen, improve the problem of generating heat of projector and make it change and install in the car near the position of window, realize the projection of small angle.
Wherein, the utility model provides a first light-passing board 1, second light-passing board 7 can be tempering or ordinary inorganic glass, also can be organic glass, and first light-passing board 1, second light-passing board 7 also can be laminated glass's combination and improve glass's whole security. When the first light-transmitting plate 1 and the second light-transmitting plate 7 use the flat glass, the glass can be used for windows of buildings, the first light-transmitting plate 1 and the second light-transmitting plate 7 can also be curved glass, curved functional laminated glass suitable for vehicles can be obtained on occasions using the curved glass, most of the glass is used for side windows of the vehicles, and the glass can also be suitable for windows at other positions of the vehicles.
Wherein, when projection arrangement 8 starts the projection, the side window glass starts the dimming function, makes the whole transmissivity of side window glass adjust to be less than 5%, prefers the transmissivity that is less than 1% under the sufficient circumstances of sunshine, can have better shading and improve the effect of projection definition. The dimming film 5 uses a currently common dimming technology, preferably one of SPD (suspended particle device), EC (electro chromic), and LC (liquid crystal or dye liquid crystal), and the use of PDLC (polymer dispersed liquid crystal) dimming technology can also achieve the object but has a poor effect, because the PDLC dimming film itself is also a display support layer suitable for projection content, and the PDLC dimming film has low resolution of an image on the same side and poor visual perception, the use of the PDLC dimming film is not recommended here.
The display support layer 3 preferably displays a display film sheet such as a photonic film having high brightness, full color, high transparency, and low haze, the photonic film is an artificial microstructure formed by periodically arranging media with different refractive indexes, and the artificial microstructure can have a high reflection effect on a visible light waveband to improve the display performance, can display a colorful picture, and has a certain transparency, for example, the photonic film disclosed in chinese patent CN 201710467082.
In the vehicle-mounted environment, in order to achieve a better projection display effect, the haze of the used display bearing layer 3 is less than 5%, preferably less than 3%, and the contrast of the display bearing layer 3 is greater than 7:1, preferably greater than 20: 1. The thickness of the support layer 3 is shown to be selected from 0.05mm to 1mm, preferably 0.1mm to 0.7 mm. The use of the display bearing layer 3 enables the projection to have better resolution, better visual effect and richer colors. Meanwhile, in order to adapt to the existing glass production process, the material of the display bearing layer 3 is selected to meet the existing high-temperature and high-pressure laminated glass production process, and the maximum display brightness of the display bearing layer 3 is less than 800Cd/m 2.
In one embodiment, a third adhesive layer 6 is further laminated between the light adjusting film 5 and the display support layer 3 to increase the adhesion between the light adjusting film 5 and the display support layer 3, thereby further improving the safety of the entire side window glass. The utility model discloses what the tie coat mentioned in use is that the tie coat material that the automotive industry is commonly used is like PVB, EVA etc for improve whole side window laminated glass's security performance.
In one embodiment, the projection ratio of the projection device 8 is controlled to be less than 0.6, and the projection device 8 can be installed at a position close to the side window glass.
In an embodiment, the lumen value of the projection device 8 is between 50 and 1000. Since the display carrier layer 3 and the light-adjusting film 5 reduce the requirements for the projection device 8, a better projection effect can be achieved with a lower lumen value.
Therefore, the size of the projection device 8 can be controlled to be less than 100mm x 30mm, and the power of the projection device can be controlled to be less than 30w, so that a natural heat dissipation mode can be used, and noise is reduced.
In one embodiment, the three layers of the second adhesive layer 4, the light modulating film 5 and the third adhesive layer 6 can be replaced by a simple low transmittance adhesive layer having a transmittance of less than 44%, preferably less than 18%, even less than 10%.
