It should be understood that the vehicle window glass according to the embodiments of the present invention, including but not limited to a front windshield glass, a rear windshield glass, a skylight glass, a door glass or a quarter glass, can provide different display images based on different requirements.

Fig. 1a and 1b each show different ways of applying a window pane 3 with a projection function in a vehicle 1. It should be noted that the vehicle 1 is only shown in a schematic way to indicate that the on-board projector 2 is arranged inside the vehicle, for example in the ceiling of the vehicle; the window pane 3 is also only shown in a schematic way to indicate an arrangement on a vehicle, and does not mean that the window pane 3 is arranged at a specific location inside the vehicle, for example the window pane is a front windscreen. In fig. 1a, the observer 42 is, for example, a driver or a passenger in a vehicle, the window glass 3 is in a front projection mode, and since the window glass 3 has an imaging layer, more light is reflected, and the observer 42 can directly observe the image projected by the vehicle-mounted projector 2 in the vehicle. In fig. 1b, the observer 41 is located outside the vehicle, the window glass 3 is in a rear projection mode, and also because the window glass 3 has an imaging layer, more light is transmitted, and the observer 41 can observe the image projected by the projector 2 outside the vehicle.

In the automotive industry, laminated glass is used in particular as front windshield glass to improve ride safety. By way of example of a front windscreen, and as shown in connection with fig. 2, a vehicle glazing in the form of a laminated glass may comprise a glass body 100, the glass body 100 comprising a first glass 110, a second glass 120 and an interlayer disposed between the first glass 110 and the second glass 120. The first glass 110, which may be referred to as an outer glass, has a first surface 111 facing the vehicle exterior and a second surface 112 facing the vehicle interior; the second glass 120, which may be referred to as an inner glass, has a third surface 121 facing the second surface 112 and a fourth surface 122 facing the vehicle interior. The first glass 110 and the second glass 120 are bonded together by an interlayer (e.g., pvb (polyvinyl butyral), polyvinyl butyral, or eva (ethylene vinyl acetate)). According to an embodiment of the present invention, the imaging layer 200 is laminated between the first glass 110 and the second glass 120. Alternatively, the imaging layer 200 may be attached directly to the second surface 112 of the first glass 110 or the third surface 121 of the second glass 120. In certain embodiments, as shown in fig. 2, the imaging layer 200 is optionally attached to the second surface 112 of the first glass 110 or the third surface 121 of the second glass 120, or between the second surface 112 of the first glass 110 and the third surface 121 of the second glass 120, respectively, through the intermediate layers 130, 140. For example, the imaging layer 200 may be attached to the second surface 112 of the first glass 110 by a PVB interlayer 130, the imaging layer 200 itself being provided with an adhesive backing, the other side of which may be directly adhered to the third surface 121 of the second glass 120. Alternatively, the imaging layer 200 may be attached to the third surface 121 of the second glass 120 by a PVB interlayer 140, the imaging layer 200 itself being provided with an adhesive backing, the other side of which may be directly bonded to the second surface 112 of the first glass 110. Alternatively, imaging layer 200 may be attached to second surface 112 of first glass 110 by PVB interlayer 130 and to third surface 121 of second glass 120 by PVB interlayer 140.

Further, although not shown in fig. 2, the imaging layer 200 may optionally be located on the fourth surface 122 of the second glass 120. When the imaging layer 200 is optionally positioned on the fourth surface 122 of the second pane of glass 120, the imaging layer 200 meets the requirements of aging, weatherability, and window lift.

For front and rear door glass or rear windshield glass, tempered glass is often used. In this case, as shown in fig. 3, the window glass in the form of tempered glass may include a glass body 300, the glass body 300 having an outer surface 310 facing the outside of the vehicle and an inner surface 320 facing the inside of the vehicle, and the imaging layer 200 may be directly attached to the inner surface 320, or may also be attached to the inner surface 320 through an intermediate layer.

The glazing may comprise one or more imaging layers, whether laminated or toughened, optionally as a front and/or rear projection layer. Fig. 4 illustrates an alternative embodiment. This embodiment is similar to fig. 2, except that the glazing comprises a plurality of imaging layers, which may both be front or rear projection layers, or as shown both front and rear projection layers 210 and 220. In this way, the window pane can be divided into different functional regions as required for displaying different images respectively to the interior and exterior of the vehicle.

In alternative embodiments, the imaging layer may be provided by way of a coating or layer on the glass surface, for example shaped as a film, and may be any of a variety of films that are light permeable and suitable for carrying a projected image. In certain embodiments, the imaging layer can be in the form of a light adjusting film PDLC (Polymer Dispersed Liquid Crystal). The membrane of adjusting luminance is the membrane of adjustable light through-put state, with polymer dispersed liquid crystal solidification between two-layer transparent conductive film, through the regulation of voltage, can realize that the membrane switches between transparent and non-transparent state, is transparent under the on-state, is non-transparent (visual effect is close the dull polish) under the off-state. So, when window glass is in projection image's display state, non-transparent membrane of adjusting luminance can make more light reflection under the outage state for the image that demonstrates is more clear to the inside observer of vehicle, and the projection image can't be seen to the vehicle outside simultaneously, has protected the privacy. Alternatively, the transparent dimming film in the energized state promotes more light transmission, so that the displayed image is clearer to an observer outside the vehicle; in addition, when need not to demonstrate the projection image, transparent membrane of adjusting luminance can not influence driver and passenger's driving safety in the vehicle and experience by bus under the on-state, does not influence window glass's pleasing to the eye simultaneously yet.

Fig. 5 shows another embodiment of a glazing, in this embodiment exemplified as a laminated glazing, comprising a first glazing 110 facing the exterior of the vehicle and a second glazing 120 facing the interior of the vehicle, the imaging layer 200 being laminated between the first glazing 110 and the second glazing 120 and may comprise a reflective layer 240 and a scattering layer 230. As shown by the arrows in fig. 5, the light projected by the in-vehicle projector 2 is transmitted through the second glass 120 and partially reflected at the reflective layer 240 and transmitted to the diffusion layer 230. An effective structure of the reflective layer 240 is at least one metal layer capable of providing a certain degree of light reflectivity, one of which is optionally configured as: for light incident on the reflective layer 240, about 20% -60% of the light will be reflected by the reflective layer 240, while the remainder of the light will be substantially or mostly transmitted through the reflective layer 240. Alternatively, the scattering layer 230 is formed using PVB doped with nanoparticles 231. Light incident on the scattering layer 230 undergoes Mie scattering (Mie scattering), which is scattering that occurs when the diameter of particles in the atmosphere is comparable to the wavelength of radiation, at the nano-particles 231. This scattering is mainly caused by particles in the atmosphere, such as smoke, dust, small water droplets and aerosols. The intensity of mie scattering is proportional to the square of the frequency, and the scattering is stronger in the forward direction than in the backward direction, and the directivity is more pronounced. Thus, as shown in FIG. 5, the scattered light will travel in many different directions, some toward the first glass 110 and some toward the second glass 120. That is, the scattered light includes both backward scattered light heading toward the second glass 120 and forward scattered light heading toward the first glass 110. Due to the presence of the reflective layer 240, a portion of the backscattered light, when encountering the reflective layer 240, is reflected by the reflective layer and re-travels towards the first glass 110. For the observer 41 outside the vehicle on the side of the first glass 110, their eyes can receive more light than without the reflective layer 240, thereby improving the clear contrast of the observed projected image and the overall quality of the image. For the observer 42 in the vehicle interior on the side of the second glass 120, not all light rays end up emerging from the first glass 110, but a part of the light rays emerge from the second glass 120 under the action of reflection and scattering, so that a projected image of substantial quality can likewise be observed. Based on this concept, in some embodiments, the positions of the reflective layer 240 and the scattering layer 230 may be reversed to improve the quality of the image observed by the observer 42 inside the vehicle. It is to be understood that commercially available coatings, coatings or films having equivalent functions or effects may be used as the reflective and scattering layers described above. In addition, the number of the reflecting layer and the scattering layer may be determined as needed, and is not limited to that shown in the drawings.

According to the utility model discloses, imaging layer 200 is configured to communicate with vehicle projector 2 via the human-computer interaction unit, and vehicle projector responds to the control signal that the human-computer interaction unit sent throws the image to window glass to show the image that vehicle projector 2 throws to vehicle outside and/or vehicle inside through imaging layer 200. Thus, the window glass with the imaging layer, together with the human-computer interaction unit and the on-board projector, constitutes an on-board projection system suitable for use in a vehicle.

The human-computer interaction unit may communicate with the window glass and/or the in-vehicle projector via an external interface and/or a wireless transceiver. Optionally, the external interface includes, but is not limited to, a USB interface, an HDMI interface, etc., such as using a low voltage differential signaling bus (LVDS) or Video Graphics Array (VGA) interface to connect to the window glass and/or the vehicle projector. The wireless transceiver includes, for example, a Wi-Fi chip, a bluetooth chip, etc., so as to communicate with a window glass and/or an in-vehicle projector having a wireless communication function.

Alternatively, the Human-Machine interaction unit may include at least one of a Human-Machine Interface (HMI), a head-up display (HUD), and an Advanced Driving Assistance System (ADAS). Alternatively, the human-computer interaction unit may include at least one of a voice module (e.g., microphone), an image module (e.g., camera), a key module (e.g., membrane key, mechanical key), a touch module, a gesture module (e.g., infrared sensor), and a remote control module. Therefore, the human-computer interaction unit serves as an input end of the vehicle-mounted projection system, information input by an operator in various modes is fed back to the system and output to the vehicle-mounted projector, and then the information is output to the imaging layer of the window glass in a projection mode. Alternatively, for example, a voice module, an image module, a gesture module, a remote control module, or the like may be installed in the in-vehicle projector, and communicate with, for example, a center console of the vehicle in a wired or wireless manner.

In some embodiments, the glazing further comprises a touch layer attached to the imaging layer or the inner surface of the glazing body corresponding to at least a portion of the area of the imaging layer. Optionally, the touch layer is a plating or coating or film attached to the inner surface of the glass body, e.g., a capacitive touch film. In this way, the vehicle window glass can be used as a carrier integrating the human-computer interaction function, can be conveniently suitable for various application scenes, and provides diversified user experience.

In some embodiments, the vehicle-mounted projection system may include an environment monitoring unit, and the environment monitoring unit may provide an environment monitoring signal to the human-computer interaction unit, so as to actively send a control signal to the vehicle-mounted projector through the human-computer interaction unit to project a corresponding image, or may passively send a control signal to the vehicle-mounted projector through human operation. Alternatively, the environment monitoring unit includes, for example, but not limited to, at least one of a vehicle state sensor, an ambient light sensor, and an ambient object sensor. Wherein, the vehicle state sensor can monitor at least one of the driving state, the parking state and the door opening and closing state. The ambient light sensor can monitor light outside or inside the vehicle, and can then actively or passively control and adjust, for example, the light transmittance of the light adjusting film. The environmental object sensor can monitor whether obstacles, pedestrians or vehicles exist around the vehicle, and then project appropriate images to the corresponding window glass in time.

The making and using of the present invention will become more apparent from the following description of various alternative embodiments. In the following embodiments, the in-vehicle projector is mainly placed on the ceiling of a vehicle as an example. It should be understood that the in-vehicle projector may be placed in any other area of the vehicle interior configured to project toward the window glass.
