Description

Technical Field

[0001] The present invention relates to the field of vehicles, and particularly to a glass capable of emitting light for display and a vehicle. Background Art

[0002] With the development of the intelligence and functionality of vehicle glass, intelligent display glass has gradually become one of the growth points of the automotive industry and a hot topic in vehicle engineering research. Intelligent display glass includes two types: passive light-emitting and active light-emitting. Passive light-emitting intelligent display glass includes projection-type PDLC glass, HUD head-up display glass, etc. And integrating a traditional display in transparent glass to obtain an actively light-emitting display component is one of the main technical routes of actively light-emitting intelligent display glass.

[0003] At present, the mainstream displays are mainly classified by technology into liquid crystal displays (LCDs), organic light-emitting diode displays (OLEDs), inorganic light-emitting diode displays (LEDs), etc. Due to the cutting rate of components and the design limitations of the electronic control system, most displays are square or close to square (such as several external dimensions of 16:10, 16:9, 4:3, 3:2, etc.); in addition, due to technical limitations, the light-emitting display device cannot achieve complete transparency or a transparent effect completely consistent with that of glass. Therefore, after integrating the light-emitting display device in the glass, obvious optical differences such as color, light transmittance, and haze will appear between the functional area for display and the surrounding area. In the field of vehicle glass, due to technical and aesthetic shaping requirements such as wind resistance and aesthetics, vehicle glass is often a double-curved surface, with rounded corners, or triangular, or polygonal irregular shapes. Therefore, integrating the light-emitting display device in the middle of the vehicle glass, the combination of the irregular vehicle glass and the square display device will cause a strong contrast between the opaque or semi-transparent square display functional area and the remaining fully transparent irregular substrate area, which not only affects the display effect of the display device but also gives users a poor experience in terms of aesthetics and visual perception, greatly affecting the application of transparent display glass on vehicle glass.

[0004] Regarding the problem of the poor integration effect of the light-emitting display device and the glass in the related art, no effective solution has been given yet.

[0005] Therefore, based on the experience and practice of the inventor in the relevant industry for many years, a glass capable of emitting light for display and a vehicle are proposed to overcome the defects of the prior art. Summary of the Invention

[0047] For a clearer understanding of the technical features, objectives, and effects of the present invention, the detailed implementation mode of the present invention will now be described with reference to the accompanying drawings.

[0048] Implementation mode 1

[0049] As Figure 1 shown, the present invention provides a glass capable of light-emitting display. The glass capable of light-emitting display includes a glass layer 1, a substrate layer 2, and a light-emitting display layer 3 that are stacked. At least a part of the substrate layer 2 is located at the connection position between the light-emitting display layer 3 and the glass layer 1 to transition the display effect of the light-emitting display layer 3 and the display effect of the glass layer 1, and eliminate the visual difference at the connection position between the light-emitting display layer 3 and the glass layer 1.

[0050] In the present invention, the glass layer 1, the substrate layer 2, and the light-emitting display layer 3 are stacked. Since at least a part of the substrate layer 2 is located at the connection position between the light-emitting display layer 3 and the glass layer 1, the display effect of the light-emitting display layer 3 and the display effect of the glass layer 1 can be transitioned through the substrate layer 2, so that the light-emitting display layer 3 and the glass layer 1 are visually transitioned and integrated into one (that is, the substrate layer 2 can make a natural transition between the glass layer 1 and the light-emitting display layer 3 by adjusting elements such as light transmittance, color, and gradient light transmittance). Therefore, the visual difference at the connection position between the light-emitting display layer 3 and the glass layer 1 is effectively eliminated, the compatibility between the light-emitting display layer 3 and the glass layer 1 is improved, and while obtaining a better display effect, the setting of the substrate layer 2 can provide a larger design space for the light-emitting display content, bringing a better aesthetic perception to the user.

[0051] In an alternative embodiment of the present invention, as Figure 1 shown, the number of the glass layers 1 is at least two (that is, the inner glass sheet and the outer glass sheet in the existing vehicle glass), the substrate layer 2 and the light-emitting display layer 3 are stacked and sandwiched between the two glass layers 1, and the two glass layers 1, the substrate layer 2, and the light-emitting display layer 3 are all stacked. Among them, the glass layer 1 can use a conventional vehicle glass.

[0052] Furthermore, asFigure 1 As shown, an interlayer 4 is provided between the glass layer 1 and the substrate layer 2, and / or between the glass layer 1 and the light-emitting display layer 3. The interlayer can be, for example, polyvinyl butyral (PVB), ethylene vinyl acetate, polyurethane, polypropylene, polyacrylate, polyethylene, polycarbonate, polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resin, acrylate, fluorinated ethylene-propylene, polyvinyl fluoride, and / or ethylene-tetrafluoroethylene, and / or their mixtures and / or copolymers. Through the interlayer 4, the adjacent glass layer 1 and the substrate layer 2, or the glass layer 1 and the light-emitting display layer 3 can be bonded to ensure stable connection between adjacent layers.

[0053] In an alternative embodiment of the present invention, as Figure 1 shown, the substrate layer 2 can be stacked between the glass layer 1 and the light-emitting display layer 3. Of course, the substrate layer 2 can also be stacked separately on the surface of the glass layer 1, as long as the substrate layer 2 can play a role in transitioning and fusing the display effects of the light-emitting display layer 3 and the glass layer 1. In addition, other stacked structure combinations with the same effect can also be adopted between the glass layer 1, the substrate layer 2, and the light-emitting display layer 3, which are not limited herein.

[0054] Furthermore, the substrate layer 2 can be a single-layer structure or a multi-layer structure stacked (such as: stacked between the first substrate layer, the second substrate layer, the third substrate layer to the nth substrate layer), and the specific number of layers of the substrate layer 2 is not limited herein.

[0055] Furthermore, the light-emitting display layer 3 can be a single-layer light-emitting display device or composed of multi-layer light-emitting display devices. Among them, the light-emitting display device can be a liquid crystal display (LCD), an organic light-emitting diode display (OLED), an inorganic light-emitting diode display (LED), or other display devices that can be used to display patterns or characters. The above light-emitting display devices can be opaque, semi-transparent, or transparent devices, and their visible light transmittance is 90% to 0%. The light-emitting display device can be single-sided display or double-sided display. The double-sided display light-emitting display device can simultaneously display text, numbers, and / or patterns inside and outside the vehicle.

[0056] In an alternative embodiment of the present invention, the projected area of the substrate layer 2 on the glass layer 1 is larger than the projected area of the light-emitting display layer 3 on the glass layer 1, and the projection of the substrate layer 2 on the glass layer 1 covers the projection of the light-emitting display layer 3 on the glass layer 1, so as to ensure that any connection position between the light-emitting display layer 3 and the glass layer 1 can be transitionally fused through the substrate layer 2, and to ensure the elimination of visual differences at the connection position between the light-emitting display layer 3 and the glass layer 1.

[0057] Furthermore, the area of the substrate layer 2 is larger than that of the light-emitting display layer 3 , and the area of the substrate layer 2 is smaller than or equal to that of the glass layer 1 .

[0058] In an optional embodiment of the present invention, the substrate layer 2 may be made of a material with fixed optical properties, or may be made of a device with adjustable optical properties (e.g., a device that can adjust the visible light transmittance, or adjust the color, or other optical properties according to the needs of the external environment, or a device that can adjust multiple optical properties at the same time, such as the currently available PDLC device, which can adjust the visible light transmittance and haze by voltage; or an EC device, which can adjust the visible light transmittance and color change by voltage / current).

[0059] Furthermore, the material of the substrate layer 2 can be plastic, resin, plant fiber, leather, metal, or glass, or a composite material composed of multiple of the above materials. The thickness of the substrate layer 2 is less than or equal to 4 mm, preferably less than or equal to 0.76 mm. Furthermore, the optimal thickness of the substrate layer 2 is less than or equal to 0.1 mm.

[0060] In an optional embodiment of the present invention, Figure 2 As shown, the substrate layer 2 includes a display area 202 and a substrate area 201. A shading portion 203 is provided on the periphery of the display area 202 and between the substrate area 201 and the display area 202. The shading portion 203 can block light passing through the glass layer 1 (i.e., light outside the vehicle that can pass through the glass layer 1 and enter the vehicle. Because the light outside the vehicle is brighter than the light inside the vehicle in most cases, it will affect the display effect of the light-emitting display layer 3 and the display area 202) from entering the display area 202, thereby ensuring a good display effect.

[0061] Furthermore, the display area 202 is disposed inside the substrate layer 2 , and the light shielding portion 203 is disposed around the periphery of the display area 202 .

[0062] Further, such as Figure 2 As shown, the projected area of the display region 202 on the glass layer 1 is smaller than the projected area of the light-emitting display layer 3 on the glass layer 1. Of course, the projected area of the display region 202 on the glass layer 1 may also be equal to the projected area of the light-emitting display layer 3 on the glass layer 1, and at least a portion of the light-emitting display layer 3 overlaps with the display region 202, so that light emitted by the light-emitting display layer 3 can pass through the display region 202 and the glass layer 1 and be emitted.

[0063] Furthermore, the display area 202 can be made of, but not limited to, transparent and colorless materials. Of course, the display area 202 can also be made of materials of other colors, as long as the setting of the display area 202 does not affect the display effect of the light-emitting display layer 3.

[0064] Further, the light-shielding portion 203 can be, but is not limited to, black. The visible light transmittance of the light-shielding portion 203 is less than 1%. The light-shielding portion can block the light transmitted from the back of the glass, thereby effectively reducing the interference of the background ambient light (i.e., the light outside the vehicle) on the light emitted by the light-emitting display layer 3 and obtaining a better display effect.

[0065] Further, the substrate region 201 can be transparent, translucent, opaque, black, colorless, or other colors, or a specific pattern composed of multiple of the above colors.

[0066] In an alternative embodiment of the present invention, the projection width of the light-shielding portion 203 on the glass layer 1 is greater than or equal to 10 times the line width distinguishable by the human eye and less than or equal to 0.1 times the width of the display region 202 in the same direction.

[0067] Specifically, as Figure 3 shown, if the width of the display region 202 in the horizontal direction (i.e., the left-right direction of the paper surface) is a, then the widths of the light-shielding portions 203 located on the left and right sides of the display region 202 in the horizontal direction are 0.1a; if the width of the display region 202 in the vertical direction (i.e., the up-down direction of the paper surface) is b, then the widths of the light-shielding portions 203 located on the upper and lower sides of the display region 202 in the vertical direction are 0.1b.

[0068] In this embodiment, the line width distinguishable by the human eye (i.e., the minimum distinguishable line width) can be 0.22 mm. As Figure 4 shown, since the minimum resolution angle θ of the human eye is 1.5°, assuming the distance L between the observation point (i.e., the human eye) and the display region 202 is 500 mm, then the line width distinguishable by the human eye is D = 2tan(θ / 2)L = 0.22 mm. To distinguish the light-shielding portion 203 from the display region 202 and prevent the observer from regarding the light-shielding portion 203 as part of the display region 202 in the display state, the minimum width of the light-shielding portion 203 is 2.2 mm. Among them, the larger the width of the light-shielding portion 203, the more beneficial it is to distinguish the background light and the display light. However, the larger the width of the light-shielding portion 203, the worse the appearance effect will be. Therefore, it is more appropriate to determine that the projection width of the light-shielding portion 203 on the glass layer 1 is less than 0.1 times the width of the display region 202 in the same direction. In an alternative embodiment of the present invention, as Figure 5As shown, the substrate region 201 is formed with a transition portion 2011 and a transparent portion 2012 in sequence from the side close to the display region 202 to the side far from the display region 202. The transition portion 2011 and the transparent portion 2012 can both be stacked inside the glass layer 1; alternatively, the position where the edge of the transparent portion 2012 is located can overlap with the position where the edge of the glass layer 1 is located. Through the arrangement of the transition portion 2011 and the light-shielding portion 203, the transition between the display region 202 and the transparent portion 2012 in the substrate region 201 becomes more natural.

[0069] In the display state, the region that can perform the light-shielding function (i.e., the light-shielding region) can be only the light-shielding portion 203; since the transition portion 2011 is a transition region between the transparent portion 2012 and the light-shielding portion 203, the transition portion 2011 also has a certain light-shielding effect. Therefore, the region that can perform the light-shielding function can also be jointly composed of the light-shielding portion 203 and the transition portion 2011; in addition, the region that can perform the light-shielding function can also be only the transition portion 2011. The region having the light-shielding function can be determined according to the structure of the substrate layer 2, as long as it can block the light passing through the glass layer 1 from entering the display region 202.

[0070] Among them, the specific data of each region in the substrate layer 2 are shown in Table 1 below:

[0071]

[0072] Table 1

[0073] In an alternative embodiment of the present invention, as Figure 8 shown, a pattern display portion 2013 is formed in the substrate region 201. The pattern display portion 2013 is located inside the transparent portion 2012 or occupies the position where the transparent portion 2012 is located. The display region 202 is located inside the pattern display portion 2013, so that a specific pre-designed pattern (such as: Figure 8 the house pattern in) can be displayed through the pattern display portion 2013 to improve the aesthetics of the display. Among them, the specific data of each region in the substrate layer 2 are shown in Table 2 below:

[0074]

[0075] Table 2

[0076] Furthermore, as Figures 6 to 8 shown, the number of the pattern display portions 2013 is multiple, and each pattern display portion 2013 is respectively located on both sides of the light-emitting display layer 3, so that in-vehicle display and out-of-vehicle display can be respectively performed through the in-vehicle display surface 5 and the out-of-vehicle display surface 6.

[0077] Further, the light-emitting display layer 3 is a single-sided display or a double-sided display. When the light-emitting display layer 3 is a single-sided display, the number of light-emitting display layers 3 is one layer, the light-emitting display layer 3 is disposed close to the in-vehicle display surface 5, and the substrate layer 2 is disposed close to the out-of-vehicle display surface 6, so as to perform in-vehicle display through the in-vehicle display surface 5; when the light-emitting display layer 3 is a double-sided display, the number of light-emitting display layers 3 is two layers, and the two light-emitting display layers 3 are respectively located on both sides of the substrate layer 2, so as to perform in-vehicle display and out-of-vehicle display through the in-vehicle display surface 5 and the out-of-vehicle display surface 6 respectively.

[0078] In an alternative embodiment of the present invention, as Figure 9 shown, a dimmable portion 2014 is formed in the substrate region 201 of the substrate layer 2. The dimmable portion 2014 is located within the transparent portion 2012 or occupies the position where the transparent portion 2012 is located. The display region 202 is located within the dimmable portion 2014, so that the visible light transmittance can be adjusted through the dimmable portion 2014. Among them, the dimmable portion 2014 has a dimming function. When a specified voltage and / or current is applied thereto, the dimmable portion 2014 can be adjusted to have a corresponding visible light transmittance. By setting the combination of different transmittances of the display region 202 and the dimmable portion 2014, a variety of patterns can be displayed, so as to be applicable to a variety of application scenarios. Among them, the specific data of each region in the substrate layer 2 are shown in Table 3 below:

[0081] Table 3

[0082] The features and advantages of the light-emitting displayable glass of the present invention at least include;

[0083] First, in the light-emitting displayable glass, on the basis of the light-emitting display layer 3 and the glass layer 1, a substrate layer 2 is added. The substrate layer 2 is stacked with the light-emitting display layer 3 and the glass layer 1, and at least a part of the substrate layer 2 is located at the connection position between the light-emitting display layer 3 and the glass layer 1. The display effect of the light-emitting display layer 3 and the display effect of the glass layer 1 are transitioned through the substrate layer 2, so that the light-emitting display layer 3 and the glass layer 1 are visually transitioned and integrated into one body, effectively eliminating the visual difference at the connection position between the light-emitting display layer 3 and the glass layer 1, improving the compatibility between the light-emitting display layer 3 and the glass layer 1. While obtaining a better display effect, the setting of the substrate layer 2 can provide a larger design space for the light-emitting display content, bringing a better aesthetic feeling to the user.

[0084] Second, in the light-emitting displayable glass, since the limiting conditions for the substrate region 201 in the substrate layer 2 are less, therefore, more design freedom can be given to designers, improving the aesthetic feeling of the glass display.
