The structure of the transparent car window shown in fig. 1 mainly comprises an outer layer glass 1 and an inner layer glass 2. The outer layer glass 1 may be composed of a single layer glass or a plurality of layers glass, for example, may be two layers glass, and as shown in fig. 1, is composed of a glass 1a opposite to the outer layer and a glass 1b opposite to the inner layer. The outer glass 1 and the inner glass 2 are connected by a metal aluminum frame 3 shown in fig. 1, and 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.
In addition, as shown in fig. 2, there is also a light adjusting film assembly 5 in some transparent window structures, which is typically glued to the outer glass 1. In the structure, the transparent display module 4 can enable the whole window to serve as an information display platform during working, and the window can keep certain transparency when the transparent display module 4 is closed, so that the window has a certain perspective function.
As described in the background, in view of the requirement for high transparency when no screen is displayed and the negative effect of the high transparency on the visibility of the screen displayed by the transparent display module 4, in one embodiment, a method for determining the transmittance parameter of glass is provided, which is suitable for designing glass. Suitable glasses include a first glass plate and a second glass plate disposed opposite each other. For example, a glass product such as laminated glass or hollow glass having two glass plates disposed opposite to each other may be used. The first glass plate is far away from the ambient light incident side, the transparent display module is arranged on the first glass plate, and the second glass plate is close to the ambient light side.
As shown in fig. 3, the method for determining the glass transmittance parameter includes:
S200, obtaining standard ambient illuminance in an application scene.
The illuminance refers to illuminance in which luminous flux of 1 lumen is uniformly distributed on a unit area, and is used for indicating the intensity of illumination of ambient light. The standard ambient illuminance may refer herein to the illuminance that the illuminometer acquires in the application environment of a particular glazing when the actual attitude of the illuminometer is the same as the attitude it is intended to be mounted on that glazing. Considering that the illuminometer can be a hemispherical detection instrument, at this time, the illuminance measured by the illuminometer in a state parallel to the horizontal plane and the illuminance measured by the illuminometer in a state perpendicular to the horizontal plane have different values, namely, the values measured by the illuminometer are different under the same environment light irradiation compared with the different postures of the illuminometer in a state perpendicular to the horizontal plane, based on the difference, the illuminometer is set according to the postures of the illuminometer, which are the same in the actual installation posture under the application scene, and the values measured under the postures are obtained. For example, if it is desired to determine the transmittance parameter of the vehicle-mounted safety hollow glass product, the vehicle-mounted safety hollow glass product is usually installed perpendicular to the ground plane where the vehicle is located when the vehicle is loaded, and the illuminometers are disposed on the hollow glass in parallel, the standard ambient light illuminance may refer to the illuminance measured when the illuminometers are perpendicular to the ground plane where the vehicle is located. Through the measurement, the obtained standard ambient illuminance can be ensured to truly reflect the intensity of light received by the glass product in the practical application environment, and the accuracy of the glass transmittance parameter further determined based on the standard ambient illuminance is higher.
In addition, the ambient illuminance (lux ) varies in a day and is also a quantity sensitive to weather and environment, but considering that the illuminance variation range is generally smaller or the duration of a large variation is shorter, for a determined application scene, it is generally a relatively stable illuminance, and the illuminance capable of reflecting the illuminance intensity of the ambient light in most of the time can be understood as the standard ambient illuminance, for example, the same ambient illuminance value as the standard ambient illuminance for 80% or more than 90% of the time.
For glass applied to indoor scenes, such as window glass running in a subway rail for a long time, the standard ambient illuminance of the glass is 6000lux. For glass in a scene requiring long time facing direct sunlight, such as window glass of trains, trucks, saloons and the like which mainly run on the ground, the standard ambient illuminance corresponding to the window glass is 20000lux.
S400, obtaining the typical brightness of the screen of the transparent display module.
The transparent display module is a module with a picture display function, for example, an OLED display screen attached to the first glass plate. The screen brightness of the transparent display module is the brightness when the display function is executed, and the unit is nit (nit). While displays based on different display technology routes tend to have their typical brightness values. For example, for an OLED display screen, the typical brightness of the screen may take the value of 120nit. For LCD display screens or Mini LED (LED device with chip size between 50-200 μm) display screens, the typical brightness of the screen is 200nit.
S600, inputting standard ambient illuminance and typical brightness of a screen into a visual coefficient model to obtain a visual coefficient taking a transmittance parameter of glass as a parameter, wherein the visual coefficient model is used for representing the relationship between the visual degree and the transmittance parameter of the glass.
S800, determining that the transmittance parameter meeting the constraint condition that the visibility coefficient is smaller than or equal to the visibility threshold value in the application scene is the transmittance parameter of the glass. Considering that when the ambient light intensity is too strong, if the brightness of the transparent display module is low, the user is hard to see the content of the picture displayed on the transparent display module, so that the transmittance parameter selection of the glass is restricted by setting a visibility threshold.
Specifically, an application scene of glass to be produced and manufactured and a display screen type to be adopted are determined, based on the application scene, standard ambient illuminance and typical screen brightness of a transparent display module can be obtained, a visual coefficient model can be further utilized to obtain visual coefficients, and transmittance parameters with the corresponding visual coefficients smaller than or equal to a visibility threshold value are selected as final design values so as to guide the production and manufacture of the glass.
The first glass plate is a glass plate provided with a transparent display module, and when the transparent display module is installed, the first glass plate is arranged far away from the incident side of ambient light, namely is arranged close to the user side, so that a user can conveniently watch the picture content displayed by the transparent display module, and the glass is installed according to the relative positions of each component part of the glass and the incident side of the ambient light, so that the purposes of transparency and visibility during picture display can be achieved.
In one embodiment, the transmittance parameters of the glass include the total transmittance of the glass and the transmittance of the first glass sheet, and the visual coefficient model is:
Wherein B is a visual coefficient, E is standard ambient illuminance of glass in an application scene, L is typical screen brightness of a transparent display module, T Total (S) is total transmittance of the glass, and T Inner part is transmittance of a first glass plate. According to the formula, when the visual coefficient model can represent standard ambient light irradiation, the light intensity degree of the screen emitted by the transparent display module projected to the user side through the first glass plate and the light intensity degree of the external ambient light projected to the user side through the whole glass are different, and the difference degree determines the visual degree of the display picture of the transparent display module. If the ambient brightness is too strong, but the intensity of the light projected to the user side by the transparent display module is low, the user will have difficulty in seeing the picture displayed on the transparent display module, so the selection range of the transmittance parameter is restricted by the set visibility threshold.
When the glass is used as a window, in order to facilitate a user to touch some function icons on a display screen, a touch film is often added in the transparent display module, besides a display panel is provided for displaying the screen, and the touch film generally has a certain blocking effect on light, that is, the light transmittance of the touch film is generally less than 100%, and considering the influence on the total transmittance of the glass, in one embodiment, in the case of the transparent display module 4 including the touch film 42 and the display panel 41 as shown in fig. 4, the touch film 42 may be disposed between the first glass plate 2 and the display panel 41, or the display panel 41 may be disposed between the first glass plate 2 and the touch film 42, and in addition, the touch film 42 and the display panel 41 may also be disposed on two sides of the first glass plate 2, for example, the touch film 42 may also be disposed on one side of the first glass plate 2 away from ambient light. The transparent display module 4 may also include only the display panel 41, and the transmittance parameter of the glass may include the total transmittance of the glass, the transmittance of the first glass plate 2, and the transmittance of the transparent display module 4;
the corresponding visual coefficient model is:
Wherein B is a visual coefficient, E is standard ambient illuminance of glass in an application scene, L is typical screen brightness of the transparent display module 4, T Total (S) is total transmittance of the glass, T Inner part is transmittance of the first glass plate 2, and T Display device is transmittance of the transparent display module 4. When the transparent display module 4 includes only the display panel 41, the overall transmittance of the transparent display module 4 is the transmittance of the display panel 41, and 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, and 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.
In some embodiments, the touch film 42 may be disposed near the second glass plate 1, and may be disposed on a side of the second glass plate 1 near the ambient light, so that a user may perform touch operation outside the vehicle, and the touch film 42 may also be disposed on a side of the second glass plate 1 far from the ambient light, so that the second glass plate 1 is used to protect the touch film 42.
In one embodiment, the visibility threshold of the selection range of the transmittance parameter of the constraint glass may be a value smaller than or equal to 10, for example, 10 may be selected as the visibility threshold, and through experimental verification, when the visibility threshold is 10, the determined transmittance parameter guides the formed glass structure, and when the picture is displayed, the display visibility of the transparent display module is better, the user experience is good, and in addition, when the display is not needed, the glass also can provide a better lighting effect for the user.
In one embodiment, the transmittance parameters of the glass further include the transmittance of each component except the first glass plate, as shown in fig. 5, and the step S800 of determining that the transmittance parameter satisfying the constraint condition that the visibility coefficient is less than or equal to the visibility threshold value in the application scene is the transmittance parameter of the glass includes:
S820, the transmittance of a first glass plate is given in a first preset range. The transmittance of the first glass plate can be set to be a value within the transmittance range of 85% -100%, at this time, the first glass plate can be projected to the user side with high efficiency for the light beam projected onto the first glass plate through the second glass plate, and the lighting effect is improved. For example, the first glass sheet transmittance may be given a transmittance of 90%.
And S840, obtaining the visual coefficient taking the total transmittance of the glass as a parameter based on the given transmittance and visual coefficient model of the first glass, and determining the total transmittance of the glass meeting the constraint condition.
As shown in table 1, in an indoor application scene, the standard ambient illuminance is 6000lux, an OLED is selected as a transparent display module, the typical brightness of the screen is 120nit, when each transmittance parameter of the glass is determined, the transmittance T Inner part of the first glass plate can be given to 90%, then, based on the above-mentioned visual coefficient model, the total transmittance T Total (S) is determined, and 18% or 16.2% or 15% of the total transmittance T Total (S) satisfying the visual coefficient less than or equal to 10 can be selected, so that a basis is provided for further determining the transmittance of each component contributing to T Total (S) in the glass. Similarly, for a glass product using an LCD display screen or a Mini LED display screen as a transparent display module, the typical brightness of the screen is 200nit, and when determining the transmittance parameters of each component, the same method can be used to determine that a visible coefficient is less than or equal to 10 of the total transmittance T Total (S) , for example, 30%, 27% or 15% as shown in table 1, so as to provide a basis for further determining the transmittance of each component contributing to T Total (S) in the glass.

S860, obtaining the transmittance of each component except the first glass plate, which is matched with the determined total transmittance, based on a control variable method, wherein each component except the first glass plate comprises a second glass plate and a transparent display module.
In this embodiment, given the transmittance of the first glass sheet, it is contemplated that having multiple components in the glass will generally affect the transmittance of the glass as a whole, and in order to increase the efficiency of determining the parameters, a controlled variable method is employed. For the transmittance of N components affecting the total transmittance T Total (S) , the transmittance of N-1 components (including the transmittance T Inner part of the first glass plate) is given by giving the transmittance of the rest part and determining the transmittance of the rest part, and the transmittance of the rest 1 components is determined by using the determined total transmittance T Total (S) , so that the realization mode is efficient.
In one embodiment, as shown in fig. 6, the step S860 of obtaining transmittance parameters of each component other than the first glass plate, which match the determined total transmittance, based on the control variable method includes:
s862, the transmittance of a transparent display module is given, and the transmittance of the second glass plate matched with the determined total transmittance is obtained based on the transmittance of the transparent display module.
For example, as shown in table 3, in an indoor application environment, the standard ambient illuminance of glass is 6000lux, an OLED is selected as the transparent display module, the typical brightness of the screen is 120nit, the transmittance T Inner part of the first glass plate is 90%, then based on the above-mentioned visual coefficient model, the total transmittance T Total (S) is determined, and 18% or 16.2% or 15% of the total transmittance T Total (S) satisfying the visual coefficient less than or equal to 10 can be selected, so as to provide a basis for further determining the transmittance of each component contributing to T Total (S) in the glass. Then, based on the T Total (S) , the transmittance T Display device of the transparent display module and the transmittance T Outer part of the second glass plate are determined. As shown in the first 3 sets of examples in table 3, the transmittance T Outer part of the second glass sheet can be further determined by giving the transmittance T Display device of the transparent display module set to be 38%.
In one embodiment, the step S860 of obtaining transmittance parameters of each component other than the first glass sheet that match the determined total transmittance based on the control variable method includes:
s864, giving the transmittance of a second glass plate, and obtaining the transmittance of the transparent display module matched with the determined total transmittance based on the transmittance of the second glass plate.
For example, taking table 3 as an example, for a glass product using an LCD display screen or a Mini LED display screen as a transparent display module, the typical brightness of the screen is 200nit, and when determining the transmittance parameters of each component, the same method can be used to determine a total transmittance T Total (S) with a visual coefficient less than or equal to 10. For example, 30%, 27% or 15% as shown in the last three sets of data in Table 3 provide a basis for further determining the transmittance of each component of the glass that contributes to T Total (S) . Then, the transmittance T Display device of a transparent display module is further determined by giving the transmittance T Outer part of the second glass plate as 50%.
TABLE 3 Table 3
In one embodiment, considering that the glass, for example, when it is used as a window glass, when it is used as a lighting function, the user wants to have a transmittance as high as possible, based on which we can determine a total transmittance T Total (S) satisfying the above constraint condition within a second preset range, which may be a range of transmittance of 15% or more, as a basis for determining the transmittance of each component. In particular, for those glasses without a device for adjusting the transmittance such as a light modulation film assembly, the total transmittance T Total (S) is determined within the second preset range, so that the glass as a whole is prevented from being excessively dark, and thus the requirement of glass permeability cannot be ensured.
As shown in tables 1 and 2, for the case that T Total (S) is more than or equal to 15 percent, the visualization of the glass under the application environment condition and the maintenance of certain permeability when the glass is used as a window can be realized by virtue of the combination of the components of the glass. Whereas in the case shown in table 2, T Total (S) is < 15%. In this case, simply relying on the combination of the individual components of the glass can result in the overall darkness of the glass being too dark to meet the glass permeability requirements. In this case, the problem is solved by configuring a dimming film assembly with a dimming function. When the brightness of the external environment is too high, the light-adjusting film component can improve the brightness of a screen display picture and the brightness difference of the screen display picture by reducing the transmittance of the light-adjusting film component, so that the display picture of the transparent display module is visible. And when the vehicle window is required to be lighted, the glass can be kept transparent by improving the transmittance of the dimming film component.
Since the user usually makes the transparent display module screen visible by reducing the transmittance of the light modulation film as much as possible when using the display function of the glass, only T Total (S) at the lower limit transmittance of the light modulation film can be considered.
In one embodiment, each component of the glass except the first glass plate further comprises a light adjusting film assembly, wherein the light adjusting film assembly is attached to the side surface of the second glass plate far away from the incident side of the ambient light or the side surface of the second glass plate on the incident side of the ambient light or the transparent display module, and the light adjusting film assembly is arranged opposite to the transparent display module;
As shown in fig. 6, the step S860 of obtaining transmittance parameters of respective constituent parts other than the first glass plate that match the determined total transmittance based on the control variable method includes:
s866, giving the transmittance of a transparent display module and the transmittance of a second glass plate;
s868, obtaining the lower limit transmittance of the dimming film component matched with the determined total transmittance based on the transmittance of the given transparent display module and the transmittance of the second glass plate.
As shown in table 4, taking a glass product applied in an outdoor application scenario, the standard ambient illuminance in the outdoor environment is 20000lux, when an OLED is selected as the transparent display module, the typical brightness of the screen is 120nit, when each transmittance parameter of the glass is determined, the transmittance T Inner part of the first glass plate may be given to be 90%, then based on the above-mentioned visual coefficient model, the total transmittance T Total (S) is determined, and the total transmittance T Total (S) satisfying the visual coefficients less than or equal to 10 as shown in table 4 may be selected, so as to provide a basis for further determining the transmittance of each component contributing to T Total (S) in the glass. Specifically, the lower limit transmittance T Adjustment of of the light modulation film assembly can be further determined by giving the transmittance T Display device of the transparent display module and the transmittance T Outer part of the second glass plate, and when the total transmittance T Total (S) is determined to be 5.4% as in table 4, the lower limit transmittance T Adjustment of of the light modulation film assembly is calculated by giving the transmittance T Inner part of the first glass plate to be 90%, and further giving the transmittance T Display device of the transparent display module to be 50% and the transmittance T Outer part of the second glass plate to be 90%The final determined and outputted T Adjustment of may be determined according to the accuracy of the configuration, for example, if the accuracy of the configuration is ten-thousandth, then the corresponding T Adjustment of for T Total (S) of 5.4% in table 4 is 13.333%, and if the accuracy of the configuration is ten-thousandth, the corresponding T Adjustment of for T Total (S) of 5.4% is 13.3% in table 4. For T Total (S) in Table 4 at 2.7% according to T Inner part 、T Display device and T Outer part given in the tables, the actual calculated T Adjustment of isA T Adjustment of is finally determined and output according to the accuracy of the configuration, for example, when the accuracy of the configuration is ten bits, T Adjustment of is 6.6%. Similarly, for T Total (S) of Table 4, T Adjustment of was calculated as follows from T Inner part 、T Display device and T Outer part given in the tables at T Total (S) of 0.54%A T Adjustment of is finally determined and output according to the accuracy of the configuration, for example, when the accuracy of the configuration is ten bits, T Adjustment of is 1.3%. The above-mentioned configuration of the accuracy of the transmittance parameter can be matched according to the processing accuracy that can be supported by the production line equipment for manufacturing glass products.
On a given basis, the determination of the transmittance parameters of the remaining component parts can be realized by a table look-up method, and the relation table is used for representing the corresponding relation between T Total (S) and the transmittance parameters of each component part.
TABLE 4 Table 4
