[0002] With the development of intelligent automotive technologies such as assisted driving and automatic driving, it has become a development trend to integrate display functions on car or motorcycle glass. In the transparent window structure with integrated display function, the display screen can make the entire window act as an information display platform when working, providing key information to users. When the display screen is turned off, the window can still maintain a certain degree of transparency, giving the window a certain perspective function.

[0003] When realizing the lighting function, the car window glass hopes to provide the highest possible transmittance.

[0057] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0058] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs.

[0059] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0060] Spatially relative terms such as "away from", "close to", "outside", "inside", etc., may be used herein to describe the relationship of one element or feature to other elements or features shown in the figures. It should be understood that the spatially relative terms include different orientations of the device in use and operation in addition to the orientation shown in the figures. For example, "outside" may become "inside" if the reference object changes.

[0061] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. In addition, the "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if there is transmission of electrical signals or data between the connected objects.

[0062] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0063] like Figure 1 The structure of a transparent vehicle window shown in the figure mainly comprises an outer layer of glass 1 and an inner layer of glass 2. The outer layer of glass 1 can be composed of a single layer of glass or a plurality of layers of glass, for example, it can be two layers of glass, such as Figure 1 As shown, it is composed of a relatively outer layer of glass 1a and a relatively inner layer of glass 1b. The outer layer of glass 1 and the inner layer of glass 2 are Figure 1 The transparent display module 4 includes an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode) screen and is attached to the inner glass 2.

[0064] In addition, if Figure 2 As shown, some transparent window structures also have dimming film components 5, which are generally glued to the outer glass 1. The transparent display module 4 in the structure can make the entire window serve as an information display platform when working, and the window can still maintain a certain degree of transparency when the transparent display module 4 is closed, so that the window has a certain perspective function.

[0065] As described in the background technology, in response to the demand for high transparency when no image is displayed, and the negative impact of the high transparency on the visibility of the image displayed by the transparent display module 4, in one embodiment, a method for determining glass transmittance parameters is provided, which is applicable to the design of glass. The applicable glass includes a first glass plate and a second glass plate that are arranged oppositely. For example, it can be a glass product with two oppositely arranged glass plates, such as laminated glass or insulating glass. Among them, the first glass plate is arranged away from the incident side of ambient light, and the transparent display module is arranged on the first glass plate, and the second glass plate is arranged close to the ambient light side.

[0066] like Figure 3 As shown, the above-mentioned method for determining glass transmittance parameters includes:

[0067] S200: Obtaining standard ambient light illumination in an application scenario.

[0068] Among them, illuminance refers to the illuminance of 1 lumen of luminous flux evenly distributed on a unit area, which is used to indicate the intensity of ambient light. The standard ambient light illuminance here can refer to the illuminance obtained by the illuminance meter in the application environment of the glass product when the actual posture of the illuminance meter is the same as the posture it is intended to be installed on the specific glass product. Considering that the illuminance meter can be a hemispherical detection instrument, at this time, the illuminance measured when the illuminance meter is parallel to the horizontal plane is different from the illuminance measured when it is perpendicular to the horizontal plane, that is, compared with the posture of the horizontal plane, the value measured by the illuminance meter will be different under the same ambient light. Based on this, the illuminance meter is set in the same posture as its actual installation posture in the application scenario, and the value measured in this posture is obtained. For example, if the transmittance parameter of a vehicle-mounted safety hollow glass product needs to be determined, the vehicle-mounted safety hollow glass product is usually installed perpendicular to the ground plane of the vehicle when it is installed on the vehicle, and the illuminance meter is set parallel to the hollow glass. At this time, the above-mentioned standard ambient light illuminance can refer to the illuminance measured when the illuminance meter is perpendicular to the ground plane of the vehicle. Through this measurement, it can be ensured that the obtained standard ambient light illuminance can truly reflect the intensity of light received by the glass product in the actual application environment, and the glass transmittance parameter further determined based on the standard ambient light illuminance is more accurate.

[0069] In addition, the ambient light illuminance (in lux) varies throughout the day and is also a quantity that is sensitive to both weather and environment. However, considering that the range of illuminance variation is usually small or the duration of large changes is relatively short, for certain application scenarios, it usually has a relatively stable illuminance. The illuminance that can reflect the intensity of ambient light most of the time can be understood as the standard ambient light illuminance. For example, the same ambient light illuminance value for more than 80% or 90% of the time can be used as the standard ambient light illuminance.

[0070] For glass used in indoor scenes, such as the window glass of a car running for a long time inside a subway track, the standard ambient light illuminance can be 6000 lux. For glass that needs to face direct sunlight for a long time, such as the window glass of trains, trucks and cars that mainly travel on the ground, the corresponding standard ambient light illuminance can be 20000 lux.

[0071] S400: Acquire the typical screen brightness of the transparent display module.

[0072] A transparent display module refers to a module with a picture display function, for example, it can be an OLED display attached to the first glass plate. The screen brightness of the transparent display module is the brightness when the display function is performed, and the unit is nit. Display screens based on different display technology routes often have their typical brightness values. For example, for an OLED display screen, the typical screen brightness can be 120nit. For an LCD display screen or a Mini LED (LED device with a chip size between 50 and 200μm) display screen, the typical screen brightness can be 200nit.

[0073] S600: inputting the standard ambient light illumination and the typical brightness of the screen into a visibility coefficient model to obtain a visibility coefficient with the transmittance parameter of the glass as a parameter; the visibility coefficient model is used to characterize the relationship between the visibility of the glass and the transmittance parameter.

[0074] S800: Determine the transmittance parameter that satisfies the constraint condition that the visibility coefficient is less than or equal to the visibility threshold in the application scenario as the transmittance parameter of the glass. Considering that when the ambient light intensity is too strong and the brightness of the transparent display module is relatively low, it is difficult for the user to see the content of the picture displayed on the transparent display module, so a visibility threshold is set to constrain the selection of the transmittance parameter of the glass.

[0075] Specifically, the application scenario of the glass to be manufactured and the type of display screen to be used are determined. Based on this, the standard ambient light illumination and the typical screen brightness of the transparent display module under the application scenario can be obtained. The visibility coefficient model can be further used to obtain the visibility coefficient, and the transmittance parameters whose corresponding visibility coefficients are less than or equal to the visibility threshold are selected as the final design values ​​to guide the production of the glass.

[0076] The first glass plate refers to a glass plate provided with a transparent display module. When installed, the first glass plate is arranged away from the ambient light incident side, that is, arranged close to the user side, so that the user can watch the picture content displayed by the transparent display module conveniently. The glass is installed according to the relative positions of the various glass components and the ambient light incident side described above, which can take into account the purposes of transparency and visibility when displaying pictures.

[0077] In one embodiment, the transmittance parameter of the glass includes the total transmittance of the glass and the transmittance of the first glass plate; the visibility coefficient model is:

[0078]

[0079] Among them, B is the visibility coefficient, E is the standard ambient light illumination of the glass in the application scenario, L is the typical screen brightness of the transparent display module, T 总 is the total transmittance of the glass, T 内 is the transmittance of the first glass plate. As can be seen from the formula, the visibility coefficient model can characterize the difference between the light intensity of the screen emitted by the transparent display module projected to the user side through the first glass plate and the light intensity of the external ambient light projected to the user side through the entire glass when the standard ambient light is irradiated. The difference determines the visibility of the display screen of the transparent display module. If the ambient light brightness is too strong, but the light intensity projected to the user side by the transparent display module is low, it will be difficult for the user to see the picture displayed on the transparent display module. Therefore, the visibility threshold set above is used to constrain the selection range of the transmittance parameter.

[0080] When the glass is used as a car window, in order to facilitate the user to touch some functional icons on the display screen, in addition to the display panel for displaying the screen, a touch film is often added to the transparent display module. The touch film usually has a certain blocking effect on light, that is, the light transmittance of the touch film is usually less than 100%. Considering its influence on the total transmittance of the glass, in one embodiment, for example Figure 4 In the case of the transparent display module 4 including the touch film 42 and the display panel 41 shown, the touch film 42 can be arranged between the first glass plate 2 and the display panel 41, or the display panel 41 can be arranged between the first glass plate 2 and the touch film 42. In addition, the touch film 42 and the display panel 41 can also be arranged on both sides of the first glass plate 2, such as the touch film 42 can also be arranged on the side of the first glass plate 2 away from the ambient light. The transparent display module 4 can also include only the display panel 41, and the transmittance parameter of the glass can include the total transmittance of the glass, the transmittance of the first glass plate 2, and the transmittance of the transparent display module 4;

[0081] The corresponding visibility coefficient model is:

[0082]

[0083] Wherein, B is the visibility coefficient, E is the standard ambient light illumination of the glass in the application scenario, L is the typical screen brightness of the transparent display module 4, T 总 is the total transmittance of the glass, T 内 is the transmittance of the first glass plate 2, T 显is the transmittance of the transparent display module 4. When the transparent display module 4 only includes the display panel 41, the overall transmittance of the transparent display module 4 is the transmittance of the display panel 41; when the transparent display module includes the touch film 42 and the display panel 41, the overall transmittance of the transparent display module 4 is the superposition of the effects of the respective transmittances of the two; the transmittance of the transparent display module 4 may be the product of the transmittance of the display panel 41 and the transmittance of the touch film 42.

[0084] In some embodiments, the touch film 42 may also be disposed close to the second glass plate 1, and may be disposed on the side of the second glass plate 1 close to the ambient light, so that the user can perform touch operations outside the vehicle. The touch film 42 may also be disposed on the side of the second glass plate 1 away from the ambient light, and the second glass plate 1 may be used to protect the touch film 42.

[0085] In one of the embodiments, the visibility threshold of the transmittance parameter selection range of the constrained glass can be a value less than or equal to 10. For example, 10 can be selected as the visibility threshold. After experimental verification, when the visibility threshold is selected as 10, the determined transmittance parameter guides the formed glass structure. When displaying the picture, the display visibility of the transparent display module is better and the user experience is good. In addition, when display is not required, the glass can also provide users with better lighting effects.

[0086] In one embodiment, the transmittance parameter of the glass also includes the transmittance of each component except the first glass plate, such as Figure 5 As shown, step S800 of determining the transmittance parameter that satisfies the constraint condition that the visibility coefficient is less than or equal to the visibility threshold in the application scenario as the transmittance parameter of the glass includes:

[0087] S820: The transmittance of the first glass plate is set within a first preset range. The transmittance of the first glass plate can be set to a value within a transmittance range of 85% to 100%. At this time, the first glass plate can efficiently project the light beam projected onto it through the second glass plate to the user side, thereby improving the lighting effect. For example, the transmittance of the first glass plate can be set to 90%.

[0088] S840: Based on the given transmittance and visibility coefficient model of the first glass, obtain a visibility coefficient with the total transmittance of the glass as a parameter, and determine a total transmittance of the glass that meets the constraint condition.

[0089] As shown in Table 1, in indoor application scenarios, the standard ambient light illuminance is 6000 lux, and OLED is selected as the transparent display module, and its typical screen brightness is 120 nit. When determining the transmittance parameters of the glass, the transmittance T of the first glass plate can be given. 内 is 90%, and then based on the above visibility coefficient model, a total transmittance T is determined.总 , you can choose 18% or 16.2% or 15% which meet the total transmittance T of the visible coefficient less than or equal to 10 总 To further determine the T 总 Similarly, for glass products that use LCD displays or Mini LED displays as transparent display modules, the typical screen brightness is 200nit. When determining the transmittance parameters of each component, the same method can be used to determine a total transmittance T with a visible coefficient less than or equal to 10. 总 , for example, 30%, 27% or 15% as shown in Table 1, to further determine the T 总 Provides a basis for the transmittance of each contributing component.

[0090] Table 1

[0092] As shown in Table 2, taking a glass product used in an outdoor application scenario as an example, the standard ambient light illumination in the outdoor environment is 20000 lux. When OLED is selected as a transparent display module, the typical screen brightness is 120 nit. When determining the transmittance parameters of the glass, the transmittance T of the first glass plate can be given. 内 is 90%, and then based on the above visibility coefficient model, a total transmittance T is determined. 总 , you can choose 5.4%, 2.7% or 0.54% as shown in Table 2, which satisfies the total transmittance T of the visible coefficient less than or equal to 10. 总 To further determine the T 总 Similarly, for glass products that use LCD displays or Mini LED displays as transparent display modules, the typical screen brightness is 200nit. When determining the transmittance parameters of each component, the same method can be used to determine a total transmittance T with a visible coefficient less than or equal to 10. 总 , for example, 9.0%, 4.5% or 0.9% as shown in Table 2, to further determine the glass T 总 Provides a basis for the transmittance of each contributing component.

[0095] S860: Based on the control variable method, obtain the transmittance of each component except the first glass plate that matches the determined total transmittance; the components except the first glass plate include: a second glass plate and a transparent display module.

[0096] In this embodiment, after the transmittance of the first glass plate is given, considering that glass usually has multiple components that will comprehensively affect the transmittance of the glass as a whole, in order to improve the efficiency of determining parameters, the control variable method is used. 总 The transmittance of the N components of the glass sheet is determined by first giving the transmittance of the N-1 components (including the transmittance of the first glass sheet T 内 ), and then use the total transmittance T determined above 总 , to determine the transmittance of the remaining component, this implementation method is efficient.

[0097] In one embodiment, if Figure 6 As shown, based on the control variable method, step S860 of obtaining transmittance parameters of components other than the first glass plate that match the determined total transmittance includes:

[0098] S862: Given a transmittance of a transparent display module, and based on the transmittance of the transparent display module, obtaining a transmittance of a second glass plate that matches the determined total transmittance.

[0099] For example, as shown in Table 3, in an indoor application environment, the standard ambient light illuminance is 6000 lux, OLED is selected as the transparent display module, and its typical screen brightness is 120 nit. Given the transmittance T of the first glass plate 内 is 90%, and then based on the above visibility coefficient model, a total transmittance T is determined. 总 , you can choose 18% or 16.2% or 15% which meet the total transmittance T of the visible coefficient less than or equal to 10 总 To further determine the T 总 Then, based on the T 总 , determine the transmittance T of the transparent display module 显 and the transmittance T of the second glass plate 外 As shown in the first three groups of examples in Table 3, the transmittance T of a given transparent display module can be 显 is 38%, to further determine the transmittance T of the second glass plate 外 .

[0100] In one embodiment, based on the control variable method, the step S860 of obtaining transmittance parameters of each component except the first glass sheet that matches the determined total transmittance includes:

[0101] S864: Given a transmittance of a second glass plate, and based on the transmittance of the second glass plate, obtaining a transmittance of a transparent display module that matches the determined total transmittance.

[0102] For example, taking Table 3 as an example, for glass products using LCD display screens or Mini LED display screens as transparent display modules, the typical brightness of the screen is 200nit. When determining the transmittance parameters of each component, the same method can be used to determine a total transmittance T with a visibility coefficient less than or equal to 10. 总 For example, as shown in the last three groups of data in Table 3, 30%, 27% or 15%, in order to further determine the glass T 总 Then, by giving the transmittance T of the second glass sheet 外 is 50%, to further determine the transmittance T of a transparent display module 显 .

[0103] Table 3

[0105] In one embodiment, considering that the glass, for example, is used as a car window glass, when it serves as a lighting function, the user hopes that the transmittance is as high as possible. Based on this, we can determine a total transmittance T that satisfies the above constraint conditions within the second preset range. 总 As a basis for determining the transmittance of each component, the second preset range can be a range where the transmittance is greater than or equal to 15%. Especially for those glasses that do not have a device for adjusting transmittance such as a dimming film assembly, the total transmittance T is determined within the second preset range. 总 , it can avoid the glass being too dark as a whole, thus failing to meet the requirements for glass transparency.

[0106] As shown in Tables 1 and 2, for T 总 ≥15%, the combination of the glass components can achieve the visualization of the glass under the application environment conditions and maintain a certain degree of transparency when used as a window. 总 <15%. In this case, simply relying on the combination of the components of the glass will make the overall darkness of the glass too dark and unable to meet the requirements of glass transparency. In this case, the problem is solved by configuring a dimming film component with a dimming function. The dimming film component has a lower limit transmittance. When the brightness of the external ambient light is too high, the brightness of the screen display image can be increased by reducing the transmittance of the dimming film component and the brightness difference between the screen display image and the brightness of the screen display image, so that the transparent display module display image can be visible. When the car window lighting is required, the glass transparency can be kept by increasing the transmittance of the dimming film component.

[0107] Because when users use the display function of glass, they usually make the transparent display module visible by lowering the transmittance of the dimming film as much as possible, so only the T value at the lower limit transmittance of the dimming film can be considered.总 .

[0108] In one embodiment, the glass components other than the first glass plate further include a dimming film assembly, the dimming film assembly is attached to a side of the second glass plate away from the ambient light incident side or to a side of the second glass plate on the ambient light incident side or to the transparent display module, and the dimming film assembly is arranged opposite to the transparent display module;

[0109] like Figure 6 As shown, based on the control variable method, step S860 of obtaining transmittance parameters of components other than the first glass plate that match the determined total transmittance includes:

[0110] S866: Given a transmittance of a transparent display module and a transmittance of a second glass plate;

[0111] S868: Based on the given transmittance of the transparent display module and the transmittance of the second glass plate, obtain a lower limit transmittance of the dimming film assembly that matches the determined total transmittance.

[0112] As shown in Table 4, taking a glass product used in an outdoor application scenario as an example, the standard ambient light illumination in the outdoor environment is 20000 lux. When OLED is selected as a transparent display module, the typical screen brightness is 120 nit. When determining the transmittance parameters of the glass, the transmittance T of the first glass plate can be given as 内 is 90%, and then based on the above visibility coefficient model, a total transmittance T is determined. 总 , you can choose 5.4%, 2.7% or 0.54% as shown in Table 4, which satisfies the total transmittance T of the visible coefficient less than or equal to 10. 总 To further determine the T 总 Specifically, the transmittance T of the given transparent display module can be used to determine the transmittance of each component that contributes to the display. 显 and the transmittance T of the second glass plate 外 To further determine the lower limit transmittance T of the dimming film assembly 调 , as shown in Table 4, determine a total transmittance T 总 When the transmittance T of the first glass plate is 5.4%, 内 The transmittance of the transparent display module is 90%. 显 is 50% and the transmittance of the second glass plate is T 外 is 90%, thus the lower limit transmittance T of the dimming film assembly is calculated 调 for The final determined and output T 调 It can be determined according to the accuracy of the configuration. For example, if the accuracy of the configuration is ten thousandths, then T in Table 4 总The corresponding T 调 is 13.333%. If the configured accuracy is tenths, then T 总 The corresponding T 调 It is 13.3% in Table 4. 总 When the T is 2.7%, the 内 、T 显 and T 外 , the actual calculated T 调 for According to the accuracy of the configuration, a T is finally determined and output 调 , for example, when the configuration accuracy is tenths of a decimal place, T 调 is 6.6%. Similarly, for Table 4, T 总 When it is 0.54%, according to the T 内 、T 显 and T 外 , the actual calculated T 调 for According to the accuracy of the configuration, a T is finally determined and output 调 , for example, when the configuration accuracy is tenths of a decimal place, T 调 The configuration of the above transmittance parameter accuracy can be matched and set according to the processing accuracy that can be supported by the production line equipment for manufacturing glass products.

[0113] Based on the given, the transmittance parameters of the remaining components can be determined by looking up a table. The relationship table is used to characterize T 总 And the correspondence between the transmittance parameters of each component.

[0116] If a given T is found 总 Too small, want to adjust T 总 To adjust the overall darkness of the glass, the lower limit transmittance of the dimming film assembly can be further changed to adjust T 总 .
