Referring to fig. 1, 2, 3 and 5, embodiments provide a progressive glass comprising,
a light-transmitting substrate 1;
an optical film disposed on one side of the light-transmitting substrate; wherein, the liquid crystal display device comprises a liquid crystal display device,
the light transmittance of the optical film is gradually changed from one edge to the other edge.
In an embodiment, the optical film is in a form of gradually changing light transmittance, wherein: the part with higher light transmittance is used together with the display device, so that the part can be used as a mirror while presenting pictures to the outside when being used as display equipment and can be used as a mirror when not being used; the other part, the lower part of light transmittance makes when using as the mirror makes the effect better, and this part need not cover in display device, therefore the lower part of light transmittance's light transmittance is less than the part of cover in display device, guarantees that the people and thing that this part presents are truer, and this part can bring better use experience for the user for the mirror promptly. The gradual change glass can be used as a mirror in daily life, and the gradual change glass can be used for meeting the daily display function, so that a user is provided with a good experience.
It should be noted that when the light transmittance of the optical film is changed, the corresponding emissivity is also changed. It is considered that when the light reflectance of a place of the optical film is changed, the light transmittance of the place of the optical film is also changed accordingly. Such as when the reflectivity of light increases somewhere in the optical film where the transmissivity of light decreases correspondingly. Specifically, in some embodiments, the optical film has an overall light reflectance of 70% and a light transmittance of 30%; in still other embodiments, the optical film has an overall light reflectance of 50% and a light transmittance of 50%, and the mirror glass from which such an optical film is used may be referred to as a semi-transparent mirror glass.
Further, the light transmittance variation range of the optical film is controlled to be 0-40%.
It can be understood that the light transmittance of the optical film gradually transits from one edge to the other edge, and the numerical control of the light transmittance gradually transits from one edge to the other edge within the range of 0-40%.
In some embodiments, the light transmittance of the optical film is gradually changed from 0% at one edge to 40% at the other edge, and the light transmittance is gradually increased in the process of changing from 0% to 40%, so as to ensure the integrity of the optical film; in other embodiments, the optical film has a light transmittance that gradually changes from 0% at one edge to 30% at the other edge; in still other embodiments, the optical film has a light transmittance that gradually transitions from 1% at one edge to 25% at the other edge.
Further, the optical film 2 includes a first reflective film 21;
a second reflection film 20 provided on the same side of the light-transmitting substrate 1 as the first reflection film 21;
the first reflective film 21 has a lower light transmittance than the second reflective film 20.
The first reflective film 21 and the second reflective film 20 in one embodiment include a first low refractive index layer 201, a first high refractive index layer 202, a second low refractive index layer 203, a second high refractive index layer 204, a third low refractive index layer 205, and an ITO layer 206.
It will be appreciated that the embodiment is to divide the optical film 2 into two parts: a part of the second reflecting film 20 for use with a display device, which ensures that a picture can be presented to the outside when used as a display device, and can be used as a mirror when not used; the other part, when used as a mirror, makes the first reflective film 21 with better effect, and the part does not need to be covered on the display device, so that the light transmittance of the first reflective film 21 is lower than that of the first reflective film 21, and the first reflective film 21 can ensure that people and things presented by the first reflective film 21 are more real, namely, the first reflective film 21 can bring better use experience to a user as a mirror.
In a specific embodiment, the light transmittance of the second reflective film 20 is controlled to be 28% -40%, the light reflectance is controlled to be 60% -70%, and the brightness of the display device is in the range of 700-1000cd/m 2 . By such cooperation, the display function as a display can be ensured, and an image can be presented to the outside, and the function as a mirror can be also realized. Meanwhile, the light transmittance of the first reflective film 21 is controlled to be 0% -25%, the light reflectance is controlled to be 75% -100%, and the light reflectance of the first reflective film 21 is set to be close to 100% as much as possible in practical operation, so that the display effect of the mirror used by a user is ensured.
The thin film layer may be produced by depositing a layer to a plurality of thin films on a substrate (typically glass), typically by physical vapor deposition such as evaporation or sputter deposition, or by chemical vapor deposition. The substrate comprises transparent glass or an acrylic plate. The optical film 2 may be disposed on one side of the substrate by means of a plating film; the optical film 2 may be produced first and then arranged on one side of the substrate by means of a film-sticking method.
In a further embodiment, referring to fig. 3 and 4, the graded glass further includes a light shielding film disposed on a side of the light-transmitting substrate away from the optical film.
It can be understood that, in order to improve the emissivity of the graded glass, the light shielding film is disposed on a side opposite to the optical film, and in an embodiment, the light shielding film is disposed corresponding to the first reflective film, so that the light transmittance of the first reflective film is closer to 0%, and the first reflective film can more truly present the user's picture when used as a mirror.
In some embodiments, referring to fig. 3 and 4, the light shielding film is formed by a silk screen ink technique commonly used in the art, where the optical film is formed by physical vapor deposition such as sputtering deposition on one side of the transparent substrate, then an ink layer is disposed on the other side of the transparent substrate opposite to the optical film by silk screen ink, and the ink layer covers only the first reflective film.
Further, referring to fig. 1 and 2, the optical film 2 further includes a connection portion 3 disposed between the first reflective film 21 and the second reflective film 20, and connecting the first reflective film 21 and the second reflective film 20, respectively.
It will be appreciated that, in order to ensure that the first reflective film 21 and the second reflective film 20 having different light reflectivities can have a better use effect, a connection portion 3 capable of smoothly transiting is provided therebetween, where the connection portion 3 is a light film, and the connection portion 3 has a function of reflecting light, and the light reflectivities thereof are controlled between those of the first reflective film 21 and the second reflective film 20, so as to avoid excessively different people or things presented by a user during use. Namely, the transition effect can be better achieved, and the phenomenon that the picture presented by the mirror is too obtrusive is avoided.
Further, referring to fig. 1 and 2, the connecting portion 3 has a gradual transition structure.
It can be understood that, when the first reflective film 21 and the second reflective film 20 are directly connected due to different light reflectivities, two different pictures appear obviously at the connection position of the two when the two are used as mirrors, that is, the picture presented by the first reflective film 21 is more real, and the picture presented by the second reflective film 20 has some chromatic aberration, so that the complete picture presented by the whole mirror glass is two spliced pictures with chromatic aberration. In the embodiment, a connection portion 3 with a smooth light reflectivity transition is added between the first reflective film 21 and the second reflective film 20, and the connection portion 3 is also an optical film 2, so that the connection between two images with chromatic aberration can be effectively reduced through the transition of the connection portion 3, and a better experience is provided for the user.
Here, the first reflective film 21 is provided on one side of the light-transmitting substrate 1, and then a connection portion 3 is provided on one side of the first reflective film 21, the light reflectance of the connection portion 3 for connecting the first reflective film 21 is close to the light reflectance of the first reflective film 21, the second reflective film 20 is provided next to the connection portion 3, and the light reflectance of the connection portion 3 and the second reflective film 20 at the contact connection position is close to or the same as each other. It is considered that the connection portion 3 is the optical film 2, and the light reflectivity of the optical film 2 is set to be directly decreased from the side contacting the first reflective film 21 to the side contacting the second reflective film 20. In an embodiment, the optical film 2 used in the connection portion 3 is formed by gradually decreasing the number of layers of the optical film 2 and/or the thickness of each layer of the optical film 2 by contacting the first reflective film 21 and contacting the second reflective film 20.
Further, referring to fig. 3 and 5, the first reflecting film 21 is provided in a gradually decreasing configuration from one side away from the second reflecting film 20 to the other side;
the second reflecting film 20 is provided in a gradually decreasing configuration from one side toward the other side near the first reflecting film 21.
It can be appreciated that the gradually decreasing structure can further avoid the problem that the light reflectivities of the first reflective film 21 and the second reflective film 20 are different, which causes too large difference between the images displayed by the first reflective film 21 and the second reflective film 20 when in use, so that the problem of poor user experience of the user occurs. Here, the first reflective film 21 is set to be gradually decreased from a place far from the second reflective film 20 to a place near to the second reflective film 20, and it is considered that the decrease is to gradually decrease the light reflectance of the first reflective film 21 from a place far from the second reflective film 20 to a place near to the second reflective film 20, and it is also considered that the light reflectance of the first reflective film 21 nearest to the second reflective film 20 is close to the light reflectance of the second reflective film 20, so that the abrupt difference between the first reflective film 21 and the second reflective film 20 caused by a user is reduced, the transition is better, and the overall effect is ensured.
In the embodiment, at the same time, the second reflective film 20 may be set to be gradually decreased from the direction approaching the first reflective film 21 to the direction separating from the first reflective film. Thus, the first reflecting film 21 and the second reflecting film 20 are formed as a gradually decreasing structure from one end face to the other end face, and the light reflectance from one end face to the other end face can be considered as gradually decreasing.
In other embodiments, only the first reflective film 21 is gradually decreased from a position far from the second reflective film 20 to a position near to the second reflective film 20, and the second reflective film 20 does not need to be gradually decreased, i.e. the second reflective film 20 is a uniform horizontal film.
Further, referring to fig. 3, 4, 5 and 6, the gradually decreasing structure is a structure in which the thickness gradually decreases from one edge to the other edge.
In the embodiment, the first reflective film 21 is gradually decreased from a position far from the second reflective film 20 to a position close to the second reflective film 20, which is considered to be in order to gradually decrease the light reflectivity of the first reflective film 21 from a position far from the second reflective film 20 to a position close to the second reflective film 20, or to be closest to the second reflective film 20, which is considered to be close to the light reflectivity of the second reflective film 20, so as to reduce the abrupt nature of aberration between the first reflective film 21 and the second reflective film 20 caused by a user, have better transition property, and ensure the overall effect.
Further, referring to fig. 3 and 5, the gradual decrease in thickness includes gradually decreasing the number of refractive layers forming the first and second reflective films 21 and 20 and/or gradually decreasing the thickness of each refractive layer of the first and second reflective films 21 and 20.
It will be appreciated that in order to control the desired gradual decrease in structure and to vary the light reflectance of the first reflective film 21 and the second reflective film 20, the number of layers forming the first reflective film 21 and the second reflective film 20 and/or the specific thickness of each layer directly are varied.
In an embodiment, referring to fig. 3 and 4, by changing the specific thickness of each of the first reflective film 21 and the second reflective film 20, the thickness of the refractive index layer of each layer is gradually changed. In a specific embodiment, the thickness of each refractive index layer of the first reflective film 21 is gradually decreased from the first reflective film 21 to the direction approaching the first reflective film; the thickness of each refractive index layer of the second reflective film 20 is set to be gradually decreased from the direction approaching the first reflective film 21 to the direction separating from the first reflective film. Here, in a specific embodiment, the first reflective film 21 and the second reflective film 20 are formed by magnetron sputtering, in which the first low refractive index layer 201 is formed by magnetron sputtering from the end of the first reflective film 21 to the end of the second reflective film 20, and the amount of magnetron sputtering is controlled gradually from the end of the first reflective film 21 to the end of the second reflective film 20, so that the first low refractive index layer 201 is formed in a structure gradually inclined from the end of the first reflective film 21 to the end of the second reflective film 20, and the arrangement of other low refractive index layers in the magnetron sputtering is the same as that of the first low refractive index layer 201.
In another embodiment, referring to fig. 5 and 6, the number of layers of the first reflective film 21 and the second reflective film 20, that is, the number of superimposed refractive index layers, is gradually changed by changing the number of refractive index layers. In a specific embodiment, the number of refractive index layers of each first reflective film 21 is gradually decreased from the distance from the first reflective film 21 to the direction approaching the first reflective film; the number of refractive index layers of each of the second reflective films 20 is set to be gradually decreased from the direction approaching the first reflective film 21 to the direction separating from the first reflective film. Here, in a specific embodiment, the first reflective film 21 and the second reflective film 20 are formed by magnetron sputtering, and when the first reflective film 21 is produced, the magnetron sputtering is performed from the end of the first reflective film 21 to the end of the second reflective film 20 to form a connected first low refractive index layer 201, that is, the first low refractive index layer 201 covers the area where the first reflective film is located and the area where the second reflective film 20 is located. The first high refractive index layer 202, the second low refractive index layer, the second high refractive index layer, and the third low refractive index layer sequentially control the coverage of magnetron sputtering from the end of the first reflective film 21 to the end of the second reflective film 20, so that the refractive index layers covered by the area where the first reflective film is located and the area where the second reflective film 20 is located are in a stepwise gradually-reduced structure.
In some embodiments, the number of refractive layers of the first reflective film 21 and the second reflective film 20 may be gradually reduced, and the thickness of each refractive layer of the first reflective film 21 and the second reflective film 20 may be gradually reduced, so as to achieve the purpose of stepwise decreasing the light reflectivity. That is, the refractive index is stepwise decreased from the end of the region where the first reflective film is located to the end of the region where the second reflective film 20 is located.
It should be noted that, the graded glass 1000 is a laminated glass with multiple layers sequentially stacked, and the principle is described below:
the ITO conductive glass is manufactured by plating a layer of indium tin oxide (commonly known as ITO) film on the basis of sodium-calcium-based or silicon-boron-based substrate glass by utilizing a magnetron sputtering method. The ITO conductive glass special for the liquid crystal display can be plated with a silicon dioxide barrier layer before the ITO layer is plated so as to prevent sodium ions on the substrate glass from diffusing into liquid crystal in the box. The substrate glass of the special ITO glass for the high-grade liquid crystal display is subjected to polishing treatment before sputtering the ITO layer so as to obtain more uniform display control. The ITO glass substrate special for the liquid crystal display generally belongs to ultra-float glass, and all coating surfaces are float tin surfaces of the glass. Therefore, the final liquid crystal display can regularly generate the condition of ripple unevenness along the float direction.
An ITO conductive glass with light reflectivity of 27-55% and semi-reflective and semi-transparent performance comprises glass, a first low refractive index layer, a first high refractive index layer, a second low refractive index layer, a second high refractive index layer, a third low refractive index layer and an ITO layer which are sequentially laminated; the material of the first low refractive index layer 201 is SiO2 or MgF2; the material of the first high refractive index layer is Nb2O5, tiO2, zrO2 or Si3N4; the second low refractive index layer is made of SiO2 or MgF2; the material of the second high refractive index layer is Nb2O5, tiO2, zrO2 or Si3N4; the material of the third low refractive index layer is SiO2 or MgF2. The ITO conductive glass has the semi-reflective and semi-transparent performance through the film layer structure with the combination of the refractive index and the refractive index, and the semi-reflective and semi-transparent optical film does not need to be additionally adhered when the ITO conductive glass is used as a touch functional sheet or a vehicle-mounted inner rearview mirror, so that the ITO conductive glass has a good visual effect in use.
The preparation method of the ITO conductive glass comprises the following steps: providing glass, cleaning and drying; sequentially performing magnetron sputtering deposition on the cleaned glass surface to obtain a first low refractive index layer 201, a first high refractive index layer, a second low refractive index layer, a second high refractive index layer, a third low refractive index layer and an ITO layer, wherein the material of the first low refractive index layer 201 is SiO 2 Or MgF 2 The material of the first high refractive index layer is Nb 2 O 5 、TiO 2 、ZrO 2 Or Si (or) 3 N 4 The material of the second low refractive index layer is SiO 2 Or MgF 2 The material of the second high refractive index layer is Nb 2 O 5 、TiO 2 、ZrO 2 Or Si (or) 3 N 4 . In the above description, the product structure and the production manner of the ITO conductive glass can be known, and the production manner of the graded glass 1000 of the present application can be referred to herein without further description.

and a display module 2000 disposed on a side of the gradation glass 1000 remote from the optical film 2.
It can be appreciated that the display module 2000 is disposed on the side of the graded glass 1000 away from the optical film 2, and the display module 2000 can display a picture through the graded glass 1000. That is, when the user stands in front of the progressive glass 1000 near the optical film 2 after the display module 2000 is powered on, the contents played by the display module 2000 can be seen. And when the display module 2000 is powered off and does not need to be played, the gradual change glass 1000 is used as a mirror, so that the daily dressing requirement of a user is met.
The display device includes a mobile phone, a display, a television, a smart mirror, an advertisement display screen, or the like, that is, the graded glass 1000 may be mounted on the display device, so that the display device has a function of substantially reflecting a mirror surface, and may also have a function of an original display device.
Further, the display module 2000 is disposed on the graded glass 1000 corresponding to the second reflective film 20 of the optical film 2.

Here, since the light reflectance of the first reflection film 21 is set to be high in the embodiment in order to ensure that the user uses the progressive glass 1000 as a mirror every day without affecting the reality of the presentation image of the mirror. Meanwhile, in order to ensure the normal display of the display module 2000, the light reflectivity of the second reflective film 20 disposed in front of the display module 2000 is set to be lower, that is, the light transmissivity is correspondingly improved, so that the light corresponding to the display module 2000 is favorable for the light of the display module 2000 to penetrate through the second reflective film 20, which is more favorable for the display module 2000 to display the content outwards, thereby achieving the purpose of saving energy.
It should be noted that, if the light transmittance of the optical film 2 is too low, the display brightness of the display module 2000 disposed behind the optical film 2 needs to be increased correspondingly, and the light emitted by the display module 2000 can be displayed to the outside through the optical film 2, so that not only more electric quantity is consumed, but also the use cost is increased; the light transmittance of the optical film 2 is correspondingly improved, so that the display brightness of the display module 2000 arranged behind the optical film 2 is correspondingly reduced, and the display module 2000 can be ensured to display contents to the outside, thereby reducing energy consumption and reducing use cost.
Further, the area of the second reflective film 20 is not smaller than the area of the display module 2000.
It can be appreciated that when the display module 2000 is matched with the second reflective film 20, the display area of the display module 2000 for displaying cannot be larger, so that the situation that the display area of the display module 2000 beyond the second reflective film 20 is not good is effectively prevented, and/or the situation that the display area is inconsistent with the content image displayed by the second reflective film 20 due to the fact that the light transmittance is too great is brought to bad experience for a user.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application, and are intended to be included within the scope of the appended claims and description. In particular, the technical features mentioned in the respective embodiments may be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
