[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0052] In the description of the subsequent embodiments, the word "connected" or "connected" should be understood to mean direct connection, indirect connection, or integral molding.

[0053] This application provides a glass 1, see Figure 1 and Figure 2 .

[0054] The glass 1 includes a first glass plate 11 , a second glass plate 12 , a front light guide plate 13 and a dimming display device 2 .

[0055] The first glass plate 11 and the second glass plate 12 are arranged opposite to each other, and the front light guide plate 13 is arranged between the first glass plate 11 and the second glass plate 12. The dimming display device 2 is arranged between the second glass plate 12 and the front light guide plate 13. The front light guide plate 13 is used to receive the light emitted by the point light source and emit the light evenly to the dimming display device 2, providing a light source for the dimming display device 2, so that the dimming display device 2 can reflect the light, thereby displaying the picture.

[0056] In some embodiments, the front light guide plate 13 includes a light guide portion 131, a light homogenizing portion 132 and a light emitting portion 133. Along the propagation path of the light on the front light guide plate 13, the light guide portion 131, the light homogenizing portion 132 and the light emitting portion 133 are arranged in sequence. Exemplarily, the front light guide plate 13 is an ultra-thin transparent light-guiding film with a thickness of less than 100um and a transmittance of more than 90%. As shown in the figure, it can convert the light of the side-entering point light source into uniform light and form a surface light source after passing through the light guide portion 131, the light homogenizing portion 132 and the light emitting portion 133. The high transparency of the front light guide plate 13 will not affect the light transmission of the dimming display function layer in the dimming mode, and the light reflection in the display mode. Since the front light guide plate 13 has the characteristics of transparency, ultra-thinness and uniform light emission, it can be better combined with the dimming display device 2 and laminated into the interlayer of the glass 1. Exemplarily, the glass 1 provided in the present application can be used in the fields of automobile windows, building curtain walls, commercial windows, etc. When the glass 1 is applied to the automobile skylight, in the dimming mode, the light inside the car can be freely adjusted; in the display mode, the point light source can be turned on, so that the front light guide plate 13 provides the light required to be reflected by the dimming display device 2, and the color skylight pattern required for reflection and display is reflected. When the glass 1 is applied to the side windows of the car, in the dimming mode, the light inside the car can be freely adjusted; in the display mode, when the outdoor light is strong, the point light source can be turned on to reflect and display color information, which is used for information interaction and information prompts with pedestrians inside and outside the car. When the outdoor light is dim, the point light source can be turned on, and then the front light guide plate 13 can be used to provide reflected light to reflect and display the color information required for information interaction and information prompts with pedestrians inside and outside the car.

[0057] Furthermore, on the plane where light is propagated on the front light guide plate 13, the area of ​​the light guiding portion 131 is less than or equal to the area of ​​the light homogenizing portion 132, and the area of ​​the light homogenizing portion 132 is smaller than the area of ​​the light emitting portion 133. The area occupied by the light emitting portion 133 on the front light guide plate 13 is increased as much as possible, thereby increasing the amount of light emitted and improving the dimming and display effects of the glass 1.

[0058] In some embodiments, see Figure 3 The dimming display device 2 includes a plurality of dimming display units arranged in an array. The dimming display unit includes a first transparent electrode group 21, a second transparent electrode group 22, and a dimming display component 24. The first transparent electrode group 21 is used to generate a first electric field, and the second transparent electrode group 22 and the first transparent electrode group 21 together define a receiving space 23, and the second transparent electrode group 22 is used to generate a second electric field. The dimming display component 24 is arranged in the receiving space 23, and the dimming display component 24 is in a display mode driven by the first electric field, and the dimming display component 24 is in a dimming mode driven by the second electric field.

[0059] The technical solution provided in the present application utilizes the first transparent electrode group 21 to generate a first electric field or utilizes the second transparent electrode group 22 to generate a second electric field, so that the dimming display component 24 can be in a display mode when driven by the first electric field, and in a dimming mode when driven by the second electric field, thereby realizing both dimming and display functions without the need for additional display devices or dimming devices, which can reduce costs and improve the functional diversity of the dimming display device 2.

[0060] It should be noted that the first electric field and the second electric field are both split electric fields, which can realize the activation and switching of the display mode and the dimming mode by adjusting the voltage of the electric field.

[0061] In some embodiments, see Figure 6 or Fig.10 The dimming display component 24 includes a suspension and at least two charged particles 241 of different colors and opposite electrical properties. The charged particles 241 are arranged in the suspension to reflect light. The charged particles 241 are arranged in the suspension so that the charged particles 241 can swim in the suspension, and the charged particles 241 have opposite electrical properties, so that the charged particles 241 can move in different directions according to the electric field to open different modes or switch between different modes. The charged particles 241 have different colors, so that different charged particles 241 can reflect light of different colors to display the picture.

[0062] For further information, see Figure 3 or Figure 7 In the dimming mode, the second electric field drives the charged particles 241 to move toward the second transparent electrode group 22 to change the transmittance of the dimming display component 24. Exemplarily, the second transparent electrode group 22 drives the charged particles 241 to move in a direction perpendicular to the light emission direction or in a direction intersecting the light emission direction, so that the charged particles 241 avoid the light emission path as much as possible, thereby improving the transmittance of the dimming display component 24. It should be noted that the second transparent electrode group 22 drives the charged particles 241 to move, in addition to improving the transmittance, it can also reduce the transmittance, which is selected according to actual needs.

[0063] In some embodiments, see Figure 4 or Figure 5 or Figure 8 or Fig. 9In the display mode, the first electric field drives the charged particles 241 to move toward the first transparent electrode group 21, so that the dimming display component 24 displays the picture. Exemplarily, the first transparent electrode group 21 drives the charged particles 241 to move toward the light-emitting direction, so that the charged particles 241 can be located on the light transmission path, and reflect the light incident on the dimming display unit to change the color of the light, so that the reflected light appears to be the same color as the charged particles 241 used to reflect the light. It can be understood that the color of the light depends on the color of the charged particles 241 that directly reflect the light, that is, the color of the charged particles 241 located on the light-incoming side (reflecting light-emitting side) of the dimming display unit.

[0064] In some embodiments, see Figure 6 or Fig.10 The dimming display component 24 includes charged particles 241 of four different colors, and the electrical properties of at least one color of the charged particles 241 among the four colors are opposite to those of the charged particles 241 of the remaining colors. According to the principle of color mixing, generally four colors can achieve the mixed synthesis of all colors. The four colors can be white, red, green and blue. By mixing these four colors, the synthesis of almost all colors in nature can be achieved, which is convenient for the display of various pictures. In other embodiments, the four colors can also be white, magenta, yellow, cyan, or white, yellow, red, blue, or black, red, green and blue, etc. For the selection of the four colors, you can choose according to actual needs. Generally, white, red, green and blue are commonly used, which is convenient for the mixed display of other colors.

[0065] By making the electrical properties of the charged particles 241 of at least one of the four colors opposite to the charged particles 241 of the other colors, it is convenient for the charged particles 241 of the four colors to move in different directions according to the first transparent electrode group 21 or the second transparent electrode group 22, so as to realize the switching of the dimming mode and the display mode, and realize the switching of pictures of different colors in the display mode.

[0066] Furthermore, among the four colors of charged particles 241, the electrical properties of two colors of charged particles 241 are opposite to those of the other two colors of charged particles 241, so that the four colors of charged particles 241 can be driven by the electric field to achieve that both electrodes have two colors of charged particles 241, thereby improving the uniformity of distribution of the charged particles 241 in the accommodating space 23. Especially for the dimming display mode, the uniformity of distribution of charged particles 241 of different colors in the accommodating space 23 is more important. If the four colors of particles are all driven by the electric field and are located on one side of the accommodating space 23, or the three colors of charged particles 241 are located on one side and the other color of charged particles 241 is located on the other side, some of the charged particles 241 may be in the area where light passes, causing the charged particles 241 to reflect the light and affect the transmittance.

[0067] In some embodiments, the charges of charged particles 241 of different colors are different from each other, so that charged particles 241 of the same charge but different colors can switch the screen display under the drive of the first electric field, that is, charged particles 241 of the same charge but different colors can be driven by the first electric field so that the charged particles 241 of the target color are located on the light-emitting side, so that the charged particles 241 of the target color can reflect the light of the target color. As for the interaction between the electric field and the charge, the principle of splitting the electric field is utilized to realize that charged particles 241 of the same charge but different charges can be driven to the target position, and then, according to the screen color to be displayed, the charged particles 241 of the same charge but different charges are screened out to reflect the light of the target color to the target position. As for the split electric field, it is a prior art and will not be described in detail here.

[0068] In some embodiments, see Figure 6 or Fig.10 The dimming display component 24 also includes a transparent container 242, and the suspension and the charged particles 241 are both disposed in the transparent container 242. The transparent container 242 is used to confine the suspension and the charged particles 241 in the transparent container 242, so as to prevent the suspension and the charged particles 241 from causing short circuits and other effects on the first transparent electrode group 21 and the second transparent electrode group 22, and at the same time, it is also possible to prevent the suspension from leaking from the accommodating space 23. The transparent container 242 has a transparent property to minimize the influence of the container on the transmittance of light.

[0069] Furthermore, in the thickness direction of the dimming display device 2, the longitudinal section of the transparent container 242 is in a trapezoidal or elliptical shape. If the longitudinal section of the transparent container 242 is in a trapezoidal shape, the first transparent electrode group 21 is arranged outside the top side and the bottom side of the trapezoid, and the second transparent electrode group 22 is arranged outside the two waist sides of the trapezoid. When the first transparent electrode group 21 generates a first electric field and the second transparent electrode group 22 does not generate an electric field, a part of the charged particles 241 will approach the bottom side of the transparent container 242 under the action of the first electric field, and another part of the charged particles 241 will approach the top side of the transparent container 242 under the action of the first electric field. The charged particles 241 located at the top of the top side of the transparent container 242 can be used for light reflection, and the color of the reflected light is the color of the charged particles 241 themselves. When the first transparent electrode group 21 does not generate an electric field and the second transparent electrode group 22 generates a second electric field, a portion of the charged particles 241 will be close to one side of the transparent container 242 under the action of the second electric field, and another portion of the charged particles 241 will be close to the other side of the transparent container 242 under the action of the second electric field, so that there will be almost no charged particles 241 in the middle part of the transparent container 242, so that light can be transmitted through the transparent container 242 without being affected by the reflection of the charged particles 241, thereby improving the transmittance. The transmittance can also be adjusted according to the charge of the charged particles 241 and the direction and magnitude of the second electric field.

[0070] It should be noted that the transparent container 242 with a trapezoidal longitudinal section is conducive to improving the problems of uneven size and poor mechanical strength of multiple transparent containers 242, and has good mechanical properties. When curled or under pressure, the display performance is excellent. The transparent container 242 with an elliptical longitudinal section has good electrophoretic properties and better dimming properties. It can better gather the charged particles 241 to the end of the long axis of the ellipse and increase the light transmittance in the front direction of the short axis of the ellipse. Those skilled in the art can design the shape of the transparent container 242 according to actual needs.

[0071] In some embodiments, see Figures 3 to 6 or Figures 7 to 10, the first transparent electrode group 21 includes a first transparent electrode 211 and a second transparent electrode 212 that are arranged oppositely. The first transparent electrode 211 and the second transparent electrode 212 have opposite electrical properties, so that the first transparent electrode 211 and the second transparent electrode 212 can attract charged particles 241 with corresponding electrical properties to the corresponding electrode side, thereby realizing screen display and screen switching. Exemplarily, it is assumed that the charged particles 241 include white charged particles 241, blue charged particles 241, green charged particles 241, and red charged particles 241, wherein the white charged particles 241 and the red charged particles 241 are negatively charged, and the blue charged particles 241 and the green charged particles 241 are positively charged. When the screen needs to display a single color screen, such as a blue screen, it is only necessary to set the first transparent electrode 211 to a negative electrode and the second transparent electrode 212 to a positive electrode, and by adjusting the voltage difference between the first transparent electrode 211 and the second transparent electrode 212, a segmented electric field is formed, so that the blue charged particles 241 can be driven to the display side, located above the charged particles 241 of the other three colors, so that the display side can display a single blue screen. If it is necessary to display a screen other than the above four colors, the segmented electric fields in multiple different dimming display units can be controlled separately, so that the display side of multiple different dimming display units can display one or more colors of red, blue, green and white, and the colors displayed by multiple dimming display units can display the same or different colors according to the screen to be formed, thereby realizing the mixing of red, blue, white and green, and completing the display of multiple screens.

[0072] In some embodiments, the second transparent electrode group 22 includes a third transparent electrode 221 and a fourth transparent electrode 222 that are arranged opposite to each other. The third transparent electrode 221 and the fourth transparent electrode 222 have opposite electrical properties, so that the third transparent electrode 221 and the fourth transparent electrode 222 can attract charged particles 241 with corresponding electrical properties to the corresponding electrode side, thereby realizing picture dimming. Exemplarily, it is assumed that the charged particles 241 include white charged particles 241, blue charged particles 241, green charged particles 241, and red charged particles 241, wherein the white charged particles 241 and the red charged particles 241 are negatively charged, and the blue charged particles 241 and the green charged particles 241 are positively charged. When the third transparent electrode 221 is a positive electrode and the fourth transparent electrode 222 is a negative electrode, the third transparent electrode 221 can attract the negatively charged particles 241 to the third transparent electrode 221 side when it is powered on, and the fourth transparent electrode 222 can attract the positively charged particles 241 to the fourth transparent electrode 222 side when it is powered on, so that the charged particles 241 in the suspension avoid the transparent container 242 for light transmission, so as to reduce the blocking and reflection of the light by the charged particles 241, improve the transmittance, and achieve dimming. In addition, by forming a split electric field between the third transparent electrode 221 and the fourth transparent electrode 222, the electric field force can be adjusted according to the split electric field and the charge of the charged particles 241, and then the distribution of the charged particles 241 in the transparent container 242 is changed, so as to achieve stepless dimming, that is, the transmittance can be accurately adjusted according to the force on the charged particles 241, rather than only changing between the maximum and minimum dimming rate.

[0073] In some embodiments, the direction in which the third transparent electrode 221 and the fourth transparent electrode 222 are relatively arranged is perpendicular to the direction in which the first transparent electrode 211 and the second transparent electrode 212 are relatively arranged. In other words, the third transparent electrode 221 and the fourth transparent electrode 222 are perpendicular to the light emitting direction, which facilitates the dimming calculation, that is, the calculation of the transmittance, and facilitates the driving control of the charged particles 241.

[0074] In some embodiments, the first transparent electrode 211 or the second transparent electrode 212 is located on the display side of the dimming display device 2. In multiple dimming display units, the first transparent electrode 211 and the second transparent electrode 212 can be located on the same side, or partially on the same side and partially on the opposite side, without limitation, and can be selected mainly according to actual conditions. In addition, the electrical properties of the first transparent electrode 211 and the second transparent electrode 212 of different dimming display units are also controlled separately to realize the display of different pictures.

[0075] In some embodiments, see Figure 3 or Figure 7The dimming display device 2 includes a plurality of insulating columns 25, each insulating column 25 being located between adjacent third transparent electrodes 221 and fourth transparent electrodes 222 in two adjacent dimming display units, so as to form insulation between the third transparent electrodes 221 and fourth transparent electrodes 222 in adjacent dimming display units, thereby avoiding short circuits or other circuit risks between adjacent dimming display units.

[0076] Furthermore, the insulating column 25 is located between the first transparent electrode 211 and the second transparent electrode 212 to support the first transparent electrode 211 and the second transparent electrode 212 , thereby providing a support basis for the formation of the accommodating space 23 .

[0077] In some embodiments, see Figure 3 or Figure 7 The dimming display device 2 further includes a first transparent substrate and a second transparent substrate. The first transparent substrate and the second transparent substrate are arranged opposite to each other, and the first transparent electrode 211 and the second transparent electrode 212 are arranged between the first transparent substrate and the second transparent substrate. The first transparent substrate and the second transparent substrate are mainly used to fix the first transparent electrode 211, the second transparent electrode 212 and the dimming display component 24 together to protect the first transparent electrode 211, the second transparent electrode 212 and the dimming display component 24.

[0078] In some embodiments, see Fig.11 or Fig.12 Multiple dimming display components 24 can be set in one dimming display unit, and the color display of multiple dimming display units are independently controlled, so that multiple dimming display units can display different colors, and then realize the mixing of multiple colors, and realize the display of colors other than the color of the charged particles 241 themselves.

[0079] The embodiment of the present application also provides a vehicle, including a vehicle body, a vehicle door and a glass 1. The vehicle door is arranged on the vehicle body, and the glass 1 is arranged on the vehicle body and / or the vehicle door. The situation where the glass 1 is arranged on the vehicle body can be: the glass 1 serves as the front windshield 1 and / or the sunroof of the vehicle body, so that the front windshield 1 and / or the sunroof can display pictures. The situation where the glass 1 is arranged on the vehicle door can be: the glass 1 serves as the windshield 1 of the vehicle door, so that the windshield 1 at the vehicle door can display pictures for passenger entertainment. The vehicle has all the beneficial effects of the above-mentioned glass 1, and the present disclosure will not repeat them here.

[0080] It is understandable that the vehicle may be a fuel vehicle, a plug-in hybrid vehicle or a new energy vehicle, etc., and the present disclosure does not make any specific limitation on this.

[0081] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
