[0043] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] Coated glass can be applied to various fields. In the embodiments of the present disclosure, the coated glass is applied to buildings and vehicles (such as cars) for example, but the present disclosure is not limited thereto. The coated glass provided in the embodiments of the present disclosure can be applied to any appropriate field.

[0045] Buildings and automobiles use coated glass, which uses metal coating / metal film layers on the glass substrate or the glass body to achieve various desired effects, such as heat insulation and sun protection. However, metal coating has a very strong shielding effect on electromagnetic waves, especially high-frequency electromagnetic waves.

[0046] Table 1 below gives the formula for the relationship between penetration loss and signal frequency (f, in GHz) of different materials. Standard multi-pane glass is standard multi-pane glass, L glass is the penetration loss of standard multi-pane glass; IIR glass is infrared glass, L IIRglass is the penetration loss of infrared glass; Concrete is concrete, L concrete is the penetration loss of concrete; Wood is wood, L wood The penetration loss of wood.

[0047] Table 1

[0048] Material Penetration loss[dB] Standard multi-pane glass <h2 style=";text-align:left;direction:ltr"><![CDATA[L <h2 style=";text-align:left;direction:ltr"> glass <h2 style=";text-align:left;direction:ltr"> =2+0.2f]]><h2 style=";text-align:left;direction:ltr"> IIR glass <h2 style=";text-align:left;direction:ltr"><![CDATA[L <h2 style=";text-align:left;direction:ltr"> IIRglass <h2 style=";text-align:left;direction:ltr"> =23+0.3f]]><h2 style=";text-align:left;direction:ltr"> Concrete <![CDATA[L concrete =5+4f]]> Wood <![CDATA[L wood =4.85+0.12f]]>

[0049] With the deployment and application of high-frequency bands such as millimeter waves in mobile communication systems, the shielding effect (penetration loss) of metal coatings / metal films in coated glass on high-frequency signals is becoming more and more serious. For example, the penetration loss of coated glass (also called heat-insulating glass) used for heat insulation on the exterior walls of buildings increases with the increase of signal frequency f (see Table 1 above). For every 10GHz increase in signal frequency f, the signal strength attenuates by 2-3dB (energy attenuation by 1 / 2), and the penetration loss base of the glass itself is as high as 23dB (the base of concrete walls is only 5dB). It can be seen that coated glass has a great impact on signal loss.

[0050] In addition, with the use of high-frequency narrow beams, the signal beam has a stronger directional directivity (for example, the vertical beam width becomes narrower). Therefore, when outdoor network equipment (such as outdoor macrocell base stations) use high-frequency narrow beams for outdoor to indoor (O2I) coverage, or provide signal coverage for terminals in moving cars (such as mobile phones, computers, car navigation devices, etc.), they may face high penetration loss caused by glass coating / coated glass.

[0051] In this case, expanding the signal communication window of coated glass may become the most direct means. However, although the method of directly opening up a non-film-covered area on the coated glass can reduce the penetration loss of the signal, expanding the non-film-covered area will significantly reduce the desired effect of the coating itself (for example: heat preservation, UV isolation, etc.).

[0052] The exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0053] Figure 1 A schematic diagram of a scene of coated glass applied to an embodiment of the present disclosure is shown.

[0054] The coated glass provided by the embodiments of the present disclosure can be applied to Figure 1 The communication system shown in FIG. The system architecture includes a terminal 101, a server 102, a network 103 and a network device 104. Among them, Figure 1 Any terminal 101 shown can be used as a remote terminal or a relay terminal. Communication based on proximity service can be established between the remote terminal and the relay terminal. The remote terminal can access the network directly or through the relay terminal.

[0055] The network 103 is used as a medium to provide a communication link between the terminal 101, the server 102 and the network device 104, and may be a wired network, a wireless network, or a fiber optic cable, etc.

[0056] Optionally, the above-mentioned wireless network or wired network or optical fiber cable can use standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to any combination of local area network (LAN), metropolitan area network (MAN), wide area network (WAN), mobile, wired or wireless network, private network or virtual private network. In some embodiments, the data exchanged through the network is represented by technology and / or format including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technology can also be used to replace or supplement the above-mentioned data communication technology.

[0057] The user can use the terminal 101 to interact with the server 102 (or other terminals) through the network 103 and the network device 104 to receive or send messages, etc. The terminal can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device), a desktop computer, a virtual reality device, a smart home or a vehicle-mounted device, and other terminal-side devices. It should be noted that the specific type of the terminal is not limited in the embodiments of the present disclosure.

[0058] The network device 104 may be a base station, a relay, or an access point. The base station may be a base station of 5G or later versions (e.g., 5G NR NB), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of the network device is not limited in the embodiments of the present disclosure. The following examples are all taken as base stations.

[0059] Those skilled in the art will know that Figure 1The number of terminals, servers, networks and network devices in the example is only illustrative, and any number of terminals, networks and servers may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0060] exist Figure 1 In the embodiment, electronic devices or computer devices or communication devices such as the terminal 101 and the server 102 may be located inside a building or a vehicle, and the network device 104 may be located outside the building or the vehicle. The building or the vehicle may be installed with the coated glass provided by any embodiment of the present disclosure. On the one hand, through the area or sub-area on the coated glass where the metal film layer is not provided, the electronic device located inside the building or the vehicle may communicate with the network device located outside the building or the vehicle, so that the signal used for the communication is not shielded by the metal film layer in the coated glass, or the shielding is minimized; on the other hand, through the area or sub-area on the coated glass where the metal film layer is provided, the effects of the metal film layer itself, such as heat insulation and UV protection, may be better maintained.

[0061] An embodiment of the present disclosure provides a coated glass, the surface of which includes different regions, and the ratios of coating coverage areas of adjacent regions are different.

[0062] The ratio of the coating coverage area refers to the ratio of the area of ​​the metal film layer provided on the glass body of the coated glass in the region to the area of ​​the region.

[0063] In some embodiments, the coated glass includes a glass body / glass substrate. The glass body includes an upper surface and a lower surface, which may also be referred to as an inner surface and an outer surface. For example, when the coated glass is installed on the exterior wall of a building, the side facing the interior of the building is the inner surface, and the side facing the exterior of the building is the outer surface. For another example, when the coated glass is installed on a car, the side facing the interior of the car is the inner surface, and the side facing the exterior of the car is the outer surface. In some embodiments, a metal film layer may be provided on at least one surface of the glass body, such as the upper surface and / or the lower surface, or the inner surface and / or the outer surface, to form the coated glass.

[0064] In the embodiment of the present disclosure, the surface of the coated glass provided with the metal film layer is divided into different areas, and the ratio of the coating coverage area of ​​adjacent areas is different, that is, the surface of the coated glass provided with the metal film layer has at least two areas, and the coating coverage area of ​​one area is smaller than the coating coverage area of ​​the other area, so that the area with a small coating coverage area can be suitable for signal transmission to reduce the penetration loss of the signal; the area with a large coating coverage area can be used to provide functions such as heat insulation and UV protection. That is, in the embodiment of the present disclosure, by dividing the surface of the coated glass into different areas, the ratio of the coating coverage area in at least some different areas is different. By adjusting the ratio of the coating coverage area in each area, the balance between the ability of the high-frequency band or high-frequency narrow beam to penetrate the coated glass and the glass coating effect (such as heat insulation, UV protection, etc.) is adjusted.

[0065] In an exemplary embodiment, the shapes of different regions are the same, or different, or partially the same; the sizes of different regions are the same or different.

[0066] The present disclosure does not limit the shape and size of each area. Figures 2 to 6 Some examples of patterns for dividing the surface area of ​​coated glass are given, but the present disclosure is not limited thereto. Figures 2 to 6 In the embodiment, considering the narrowing of the vertical beam width, the areas divided on the surface of the coated glass form a number of horizontal strips, the horizontal strips are at the same horizontal height, or approximately at the same horizontal height, and the coating coverage area thereof is relatively low, for example, less than 100%, so as to facilitate the passage of the horizontal beam. That is, the surface of the coated glass includes a plurality of areas divided along the vertical direction and extending along the horizontal direction. The same area is at the same horizontal height, and the coating coverage area ratio of at least one area extending in the horizontal direction is relatively low, for example, 0. In the following embodiments, the X-axis is the horizontal direction, and the Y-axis is the vertical direction or the vertical direction. The horizontal direction can be taken as parallel to the ground, and the vertical direction or the vertical direction can be taken as perpendicular to the ground.

[0067] For example, Figure 2 In the embodiment, the surface of the coated glass 200 is divided into four regions 201, 202, 203, and 204 from top to bottom, which are divided in the vertical direction and extend in the horizontal direction, that is, four horizontal strips are formed. Some of the four horizontal strips have a large coating coverage area, while others have a small coating coverage area. This facilitates the passage of the horizontal beam in the case where the vertical beam bandwidth is narrowed, thereby reducing the shielding effect of the coated glass on the signal.

[0068] For example, Figure 3In the embodiment, the surface of the coated glass 300 is divided into 12 areas from top to bottom and from left to right: areas 301 to 312. At least one of the areas at the same level can form a horizontal strip. For example, taking the three areas 301 to 303 at the same level as an example, if the coating coverage area of ​​area 301 is small, it can be used as a horizontal strip alone. If the coating coverage areas of areas 302 and 301 are both small, they can be used as a horizontal strip. If the coating coverage areas of areas 301 to 303 are all small, they can be used as a horizontal strip. Therefore, in view of the narrowing of the vertical beam bandwidth, it is beneficial to the passage of the horizontal beam and reduces the shielding effect of the coated glass on the signal.

[0069] Figure 2 and Figure 3 In the embodiment, it is assumed that the shapes and sizes of various regions in the same coated glass are the same, for example, they are all rectangular or square.

[0070] For another example, Figure 4 In the embodiment, the surface of the coated glass 400 is divided into 22 regions from top to bottom and from left to right: regions 401 to 422 . Figure 4 The shape of the area of ​​the embodiment is basically a regular hexagon, and the size of each regular hexagonal area is the same. Except for the area around the coated glass 400, for example, areas 401 to 406, area 411, area 416, area 417 and area 422 have different shapes and sizes. Among them, at least one of the areas at the same horizontal height can form a horizontal strip. For example, taking the five areas 412 to 416 at the same horizontal height as an example, if the coating coverage area of ​​area 412 is small, it can be used as a horizontal strip alone. If the coating coverage areas of areas 412 and 413 are both small, they can be used as a horizontal strip. If the coating coverage areas of areas 412 to 414 are all small, they can be used as a horizontal strip. The same applies to others. Therefore, in view of the narrowing of the vertical beam bandwidth, it is beneficial to the passage of the horizontal beam and reduces the shielding effect of the coated glass on the signal.

[0071] For another example, Figure 5In the embodiment, the surface of the coated glass 500 is divided into 6 areas from top to bottom and from left to right: areas 501 to 506. Areas 501 and 506 are irregular shapes of the same size and symmetrical about the X-axis, and areas 502 and 503, and areas 504 and 505 are semi-elliptical and equal in size. Areas 502 and 504 are symmetrical about the X-axis, and areas 503 and 505 are symmetrical about the X-axis. Among them, if the coating coverage area of ​​area 501 and / or area 506 is small, it can be used as a horizontal strip to facilitate the passage of horizontal beams. If the coating coverage area of ​​area 502 and area 503 is small, it can be used as a horizontal strip to facilitate the passage of horizontal beams. If the coating coverage area of ​​area 504 and area 505 is small, it can be used as a horizontal strip to facilitate the passage of horizontal beams.

[0072] For another example, Figure 6 In the embodiment, the surface of the coated glass 600 is divided into 6 regions from top to bottom: regions 601 to 604. Regions 601 and 604 are irregular shapes of the same size and symmetric about the X axis. Regions 602 and 603 are semi-elliptical, of equal size, and symmetric about the X axis. If the coating coverage area of ​​region 601 and / or region 604 is small, it can be used as a horizontal strip to facilitate the passage of horizontal beams. If the coating coverage area of ​​region 502 and / or region 603 is small, it can be used as a horizontal strip to facilitate the passage of horizontal beams.

[0073] In the following embodiments, the black part is the coated part (coated area or coated sub-area), and the white part is the uncoated part (uncoated area or uncoated sub-area). The various coating patterns (coating coverage patterns, i.e., whether each area is covered with a metal film layer, and for areas covered with a metal film layer, the proportion of the coating coverage area of ​​the area determined is satisfied by setting or not setting a metal film layer in the sub-area) provided in the embodiments of the present disclosure, by making the areas with a lower proportion of the coating coverage area or the uncoated areas appear as horizontal strips, so that the beam penetration with narrowed vertical beam width can be enhanced. At the same time, the coated area of ​​the coated glass as a whole is larger than the uncoated area, and the uncoated sub-areas are distributed in various parts of the corresponding area, so that the coated glass can maintain its coating effect.

[0074] For another example, Figure 7In the embodiment, the coated glass 700 is divided into two areas from top to bottom: area 710 and area 720, both of which are rectangular but of different sizes. The area of ​​area 710 is smaller than that of area 720, and area 720 is covered with a metal film layer, which is conducive to maintaining the coating effect of the coated glass. Area 710 is not covered with a metal film layer (non-coated area), and area 720 is covered with a metal film layer (coated area). The proportion of the coating coverage area of ​​area 710 is 0%, and the proportion of the coating coverage area of ​​area 720 is 100%, that is, the proportions of the coating coverage areas of the two are different. And the area 710 with a coating coverage area of ​​0 is formed as a horizontal strip, which is conducive to the passage of high-frequency narrow beams.

[0075] In an exemplary embodiment, a plurality of sub-regions are distributed in at least one region; a metal film layer is disposed on the glass body in some sub-regions of the same region, and a metal film layer is not disposed on the glass body in the remaining sub-regions.

[0076] For example, Figure 8 In the embodiment, the coated glass 800 is divided into two regions from top to bottom: region 810 and region 820, both of which are rectangular but of different sizes. The area of ​​region 810 is smaller than that of region 820, and region 820 is covered with a metal film layer, which is conducive to maintaining the coating effect of the coated glass. Region 820 includes sub-region 821 and sub-region 822, sub-region 821 is covered with a metal film layer, and sub-region 822 is not covered with a metal film layer. Sub-region 821 and sub-region 822 are both square. The proportion of the coating coverage area of ​​region 810 is 0%, and the proportion of the coating coverage area of ​​region 820 is less than 100%, that is, the proportions of the coating coverage areas of the two are different. And the region 810 with a coating coverage area of ​​0 is formed as a horizontal strip, which is conducive to the passage of high-frequency narrow beams.

[0077] For another example, Fig. 9In the embodiment, the coated glass 900 is divided into three regions from top to bottom: region 910, 920 and 930, all of which are rectangular, but of different sizes. The area of ​​region 910 is smaller than that of region 920, and the area of ​​region 920 is smaller than that of region 930. Regions 920 and 930 are covered with metal film layers, which is conducive to maintaining the coating effect of the coated glass. Region 920 includes sub-region 921 and sub-region 922. Sub-region 921 is covered with a metal film layer, and sub-region 922 is not covered with a metal film layer. Sub-region 921 is semicircular, and sub-region 922 is the remaining part outside the two semicircular sub-regions 921. The proportion of the coating coverage area of ​​region 910 is 0%, the proportion of the coating coverage area of ​​region 920 is less than 100%, and the proportion of the coating coverage area of ​​region 930 is equal to 100%, that is, the proportions of the coating coverage areas of the three are different. The area 910 where the coating coverage area is 0 is formed into a horizontal strip, which is conducive to the passage of high-frequency narrow beams.

[0078] For another example, Fig.10 In the embodiment, the coated glass 1000 is divided into three regions from top to bottom: region 1010, 1020 and 1030, all of which are rectangular, but of different sizes. The area of ​​region 1010 is smaller than that of region 1020, and the area of ​​region 1020 is smaller than that of region 1030. Regions 1020 and 1030 are covered with metal film layers, which is conducive to maintaining the coating effect of the coated glass. Region 1020 includes sub-region 1021 and sub-region 1022. Sub-region 1021 is covered with a metal film layer, and sub-region 1022 is not covered with a metal film layer. Sub-region 1021 is semicircular, and sub-region 1022 is the remaining part outside the semicircular sub-region 1021. The proportion of the coating coverage area of ​​region 1010 is 0%, the proportion of the coating coverage area of ​​region 1020 is less than 100%, and the proportion of the coating coverage area of ​​region 1030 is equal to 100%, that is, the proportions of the coating coverage areas of the three are different. The area 1010 where the coating coverage area is 0 is formed into a horizontal strip, which is conducive to the passage of high-frequency narrow beams.

[0079] For another example, Fig.11In the embodiment, the coated glass 1100 is divided into three regions from top to bottom: regions 1110, 1120 and 1130, all of which are rectangular. The areas of regions 1110 and 1130 are smaller than that of region 1120, and region 1120 is covered with a metal film layer, which is conducive to maintaining the coating effect of the coated glass. Region 1120 includes sub-region 1121 and sub-region 1122, sub-region 1121 is covered with a metal film layer, and sub-region 1122 is not covered with a metal film layer. Sub-region 1121 is elliptical, and sub-region 1122 is the remaining part outside the two elliptical sub-regions 1121. The ratio of the coating coverage area of ​​regions 1110 and 1130 is 0%, and the ratio of the coating coverage area of ​​region 1120 is less than 100%. And regions 1110 and 1130 with a coating coverage area of ​​0 are both formed as horizontal strips, which is conducive to the passage of high-frequency narrow beams.

[0080] For another example, Fig.12 In the embodiment, the coated glass 1200 is divided into three regions from top to bottom: regions 1210, 1220 and 1230, all of which are rectangular. The areas of regions 1210 and 1230 are smaller than the area of ​​region 1220, and region 1220 is covered with a metal film layer, which is conducive to maintaining the coating effect of the coated glass. Region 1220 includes sub-region 1221 and sub-region 1222, sub-region 1221 is covered with a metal film layer, and sub-region 1222 is not covered with a metal film layer. Sub-region 1221 is elliptical, and sub-region 1222 is the remaining part outside the elliptical sub-region 1221. The ratio of the coating coverage area of ​​regions 1210 and 1230 is 0%, and the ratio of the coating coverage area of ​​region 1220 is less than 100%. And regions 1210 and 1230 with a coating coverage area of ​​0 are both formed as horizontal strips, which is conducive to the passage of high-frequency narrow beams.

[0081] The disclosed embodiment distributes multiple sub-areas in an area, so that some of the sub-areas are covered with a metal film layer, while other sub-areas are not covered with the metal film layer, exposing the glass body, so that the area appears to be similar to a gauze curtain or a screen window, which is between having and not having a metal film layer. As a result, the area has a coating effect (such as heat insulation, UV protection, etc.) compared to having no metal film layer, and has increased penetration of high-frequency signals or high-frequency bands or high-frequency narrow beams compared to full film coverage (i.e., the entire area is covered with a metal film layer), so that communication data, image data, sensor data, etc. can pass through the sub-area without a metal film layer unimpeded.

[0082] In the embodiment of the present disclosure, the area on the coated glass surface may include sub-areas, and the sub-areas may have a metal coating / metal film layer or may not have a metal coating / metal film layer. By adjusting whether each sub-area has a metal coating or does not have a metal coating, fine-grained adjustment of the proportion of the coating coverage area in a relatively large area is achieved.

[0083] In an exemplary embodiment, different sub-regions in the same region are of uniform size; sub-regions in different regions are of uniform size or of different sizes. That is, the sub-regions can be of uniform size or of different sizes.

[0084] In an exemplary embodiment, when the sub-regions within different regions are of different sizes, the sub-regions within different regions have gradually varying sizes.

[0085] The gradient size may be in the order of regions from top to bottom, with the corresponding sub-regions increasing or decreasing in sequence, or in the order of regions from the middle to both sides, with the corresponding sub-regions increasing or decreasing in sequence.

[0086] In an exemplary embodiment, the shape of the sub-region is a polygon / hole, or a circle / hole, or the remaining area except the hole. That is, the shape of the sub-region can be a polygon (or hole), or a circle (or hole), or the remaining area except the above-mentioned hole.

[0087] In the embodiments of the present disclosure, the coating coverage ratio may also be referred to as the coating coverage ratio, the coating ratio, or the coverage ratio. The concept opposite to the coating ratio is the hole area ratio, which refers to the ratio of the area of ​​the coated glass body without the metal film layer to the area of ​​the area in the corresponding region. The sum of the coating ratio and the hole area ratio is 100%.

[0088] For example, Fig.13 In the embodiment, the surface of the coated glass 1300 is divided into 9 areas from top to bottom: areas 1310 to 1390. The coating coverage area ratio of areas 1310, 1330, 1350, 1370 and 1390 is 0%, and they are all formed into horizontal strips, which is conducive to the passage of high-frequency narrow beams. Areas 1320, 1340, 1360 and 1380 each include multiple sub-areas, and the size and shape (square) of different sub-areas with metal film layers in the same area are the same, and the size and shape of different sub-areas without metal film layers are the same; the size and shape of sub-areas with metal film layers in different areas are also the same, and the size and shape of different sub-areas without metal film layers are the same, all of which are square. Taking area 1320 as an example, it includes sub-areas 1321 and sub-areas 1322 arranged at intervals, sub-area 1321 is covered with a metal film layer, and sub-area 1322 is not covered with a metal film layer.

[0089] For another example, Fig.14In the embodiment, the surface of the coated glass 1400 is divided into 9 areas from top to bottom: areas 1410 to 1490. The proportion of the coating coverage area of ​​areas 1410, 1430, 1450, 1470 and 1490 is 100%. Areas 1420, 1440, 1460 and 1480 each include multiple sub-areas, and the sizes and shapes of different sub-areas with metal film layers in the same area are the same, and the sizes and shapes (square) of different sub-areas without metal film layers are the same; the sizes and shapes of sub-areas with metal film layers in different areas are also the same, and the sizes and shapes of different sub-areas without metal film layers are the same. Taking area 1420 as an example, it includes sub-areas 1421 and sub-areas 1422 arranged at intervals, sub-area 1421 is covered with a metal film layer, and sub-area 1422 is not covered with a metal film layer. Fig.14 In the embodiment, the sub-regions 1422 in the region 1420 that are not covered with the metal film layer are arranged horizontally to form a horizontal strip, which is conducive to the passage of high-frequency narrow beams. The regions 1440 , 1460 , and 1480 are similar to the region 1420 .

[0090] In an exemplary embodiment, there is at least one region where the coating coverage ratio is lower than a threshold value, and the center points of the at least one region have the same height and are arranged horizontally along the same height of the surface of the coated glass. The threshold value can be set according to actual needs, for example, it can be 100%.

[0091] In the disclosed embodiment, the coated glass surface is divided into different areas, and the proportion of the coating coverage area in different at least some areas is different. Among them, there is at least one area with a low coating coverage ratio (i.e., the proportion of the coating coverage area) (less than 100%), and the center points of the at least one area with a low coating coverage ratio are at the same height, and are arranged in the horizontal direction at the same height of the coated glass surface, that is, forming horizontal strips, so as to facilitate the passage of horizontal beams. And the proportion of the coating coverage area of ​​adjacent horizontal strips (also referred to as horizontal horizontal strip areas) is different, that is, there are different proportions of coating and non-coating.

[0092] In an exemplary embodiment, multiple sub-regions without a metal film layer in at least one region are arranged horizontally along the surface of the coated glass; or, multiple sub-regions without a metal film layer in at least one region and having the same size and shape are arranged horizontally along the surface of the coated glass; or, multiple sub-regions without a metal film layer in at least one region having the same proportion of coating coverage area (here it means that the distribution of the sub-regions without a metal film layer in the region is basically uniform, which can also be referred to as the distribution density of the sub-regions without a metal film layer in the region is the same) are arranged horizontally along the surface of the coated glass.

[0093] For example, Fig.13In the embodiment, the sub-regions 1322 in the region 1320 that are not covered with the metal film layer are arranged horizontally, the sub-regions 1322 are all square in shape, different sub-regions 1322 have the same size, and the sub-regions 1322 are distributed relatively evenly in the region 1320 . Fig.14 In the embodiment, the sub-regions 1422 in the region 1420 that are not covered with the metal film layer are arranged horizontally, the sub-regions 1422 are all square in shape, different sub-regions 1422 have the same size, and the sub-regions 1422 are distributed relatively evenly in the region 1420 .

[0094] In an exemplary embodiment, multiple sub-regions with a metal film layer in at least one region are arranged horizontally along the surface of the coated glass; or, multiple sub-regions with a metal film layer in at least one region and the same size and shape are arranged horizontally along the surface of the coated glass; or, multiple sub-regions with a metal film layer in at least one region with the same coating coverage area ratio (here it means that the distribution of the sub-regions with a metal film layer in the region is basically uniform, which can also be referred to as the distribution density of the sub-regions covered with the metal film layer in the region is the same) are arranged horizontally along the surface of the coated glass.

[0095] For example, Fig.15 In the embodiment, the surface of the coated glass 1500 is divided into 11 areas extending in the horizontal direction from top to bottom: namely, areas 151 to 1511. The coating coverage area ratio of areas 151, 153, 155, 157, 159 and 1511 is 0%, and they are all formed into horizontal strips, which is conducive to the passage of high-frequency narrow beams. Areas 152, 154, 156, 158 and 1510 all include multiple sub-areas, and the sizes and shapes (circles / holes) of different sub-areas with metal film layers in the same area are the same, and the sizes and shapes of different sub-areas without metal film layers are the same; the sizes and shapes of sub-areas with metal film layers in different areas are also the same, and the sizes and shapes of different sub-areas without metal film layers are the same, all of which are square. Taking area 152 as an example, it includes sub-areas 1521 and sub-areas 1522 arranged at intervals, sub-area 1521 is covered with a metal film layer, and sub-area 1522 is not covered with a metal film layer. The sub-regions 1521 covered with the metal film layer in the region 152 are generally arranged horizontally, the apertures of the sub-regions 1521 are the same, and the sub-regions 1521 in the region 152 are basically evenly distributed.

[0096] In some embodiments, on the surface of the coated glass, the holes in the area (i.e., the sub-area not covered by the metal film layer), or the holes with the same aperture size in the area (i.e., the sub-area not covered by the metal film layer), or the holes with the same hole density in the area (i.e., the sub-area not covered by the metal film layer), are generally arranged horizontally.

[0097] like Fig.16 As shown, it is assumed here that the coating ratio of regions 151 to 1511 is alternately 0% and x%, and correspondingly, the hole area ratio of regions 151 to 1511 is alternately 100% and (100-x)%. Here, x can be set according to actual needs.

[0098] For another example, Fig.17 In the embodiment, the surface of the coated glass 1700 is divided into 11 areas extending in the horizontal direction from top to bottom: namely, areas 171 to 1711. The proportion of the coating coverage area of ​​areas 171, 173, 175, 177, 179 and 1711 is 100%. Areas 172, 174, 176, 178 and 1710 each include multiple sub-areas, and the sizes and shapes of different sub-areas with metal film layers in the same area are the same, and the sizes and shapes (circular) of different sub-areas without metal film layers are the same; the sizes and shapes of sub-areas with metal film layers in different areas are also the same, and the sizes and shapes of different sub-areas without metal film layers are the same. Taking area 172 as an example, it includes sub-areas 1721 and sub-areas 1722 arranged at intervals, sub-area 1721 is covered with a metal film layer, and sub-area 1722 is not covered with a metal film layer. Fig.17 In the embodiment, the sub-regions 1722 in the region 172 that are not covered with the metal film layer are arranged horizontally, which is conducive to the passage of high-frequency narrow beams. The regions 174, 176, 178 and 1710 are similar to the region 172.

[0099] like Fig.18 As shown, it is assumed here that the coating ratio of regions 171 to 1711 is 100% and (100-x)% alternately, and correspondingly, the hole area ratio of regions 151 to 1511 is 0% and x% alternately. Here, x can be set according to actual needs.

[0100] For example, Fig.19In the embodiment, the surface of the coated glass 1900 is divided into 9 areas extending in the horizontal direction from top to bottom: namely, areas 191 to 199. The coating coverage area ratio of areas 192, 194, 196 and 198 is 0%, and they are all formed into horizontal strips, which is conducive to the passage of high-frequency narrow beams. Areas 191, 193, 195 and 197 each include multiple sub-areas, and the sizes and shapes (circles / holes) of different sub-areas with metal film layers in the same area are the same, and the sizes and shapes of different sub-areas without metal film layers are the same; the sizes of sub-areas with metal film layers in different areas decrease from top to bottom, and the shapes are the same, all of which are circular. Taking area 191 as an example, it includes sub-areas 1911 and sub-areas 1912 arranged at intervals, sub-area 1911 is covered with a metal film layer, and sub-area 1912 is not covered with a metal film layer. The coating coverage ratio of region 199 is 100%, so as to maintain the coating effect of the coated glass together with the circular sub-region provided with the metal film layer.

[0101] For example, Fig. 20 In the embodiment, the surface of the coated glass 2000 is divided into 8 areas extending in the horizontal direction from top to bottom: namely, areas 2010 to 2080. The coating coverage area ratio of areas 2020, 2040, 2060 and 2080 is 100% to maintain the coating effect of the coated glass. Areas 2010, 2030, 2050 and 2070 each include multiple sub-areas, and the sizes and shapes (circles / holes) of different sub-areas with metal film layers in the same area are the same, and the sizes and shapes of different sub-areas without metal film layers are the same; the sizes of sub-areas without metal film layers in different areas decrease from top to bottom, and the shapes are the same, all of which are circular. Taking area 2010 as an example, it includes sub-areas 2011 and sub-areas 2012 arranged at intervals, sub-area 2011 is covered with a metal film layer, and sub-area 2012 is not covered with a metal film layer. Sub-areas at the same level are arranged horizontally to form horizontal strips, which is conducive to the passage of high-frequency narrow beams. For example, sub-areas 2012 in area 2010 are arranged horizontally to form horizontal strips, which is conducive to the passage of high-frequency narrow beams.

[0102] For example, Fig.21In the embodiment, the surface of the coated glass 2100 is divided into 9 areas extending in the horizontal direction from top to bottom: namely, areas 2110 to 2190. The ratio of the coating coverage area of ​​areas 2110 and 2190 is 100% to maintain the coating effect of the coated glass. Areas 2120 to 2180 each include multiple sub-areas, and the sizes and shapes (circles / holes) of different sub-areas without metal film layers in the same area are the same; the sizes of the sub-areas without metal film layers in different areas decrease upward from the middle, and decrease from the middle to the bottom, and the shapes are the same, all of which are circles. The sub-areas at the same horizontal height are arranged horizontally to form horizontal strips, which is conducive to the passage of high-frequency narrow beams. For example, the circular sub-areas not covered with metal film layers in area 2150 are horizontal strips, which are conducive to the passage of high-frequency narrow beams.

[0103] Fig. 22 In the embodiment, the surface of the coated glass 2200 is divided into four areas extending in the horizontal direction from top to bottom. Area 2210 includes a plurality of circular sub-areas not covered with the metal film layer in two horizontal rows, and the circular sub-areas are approximately uniformly distributed in the area 2210 (except for the edge portions). Area 2220 also includes a plurality of circular sub-areas not covered with the metal film layer, and the circular sub-areas are approximately uniformly distributed in the area 2210 (except for the edge portions). The distribution density of the circular sub-areas not covered with the metal film layer in area 2220 is lower than the distribution density of the circular sub-areas not covered with the metal film layer in area 2210. Area 2230 also includes a plurality of circular sub-areas not covered with the metal film layer, and the circular sub-areas are approximately uniformly distributed in the area 2230 (except for the edge portions). The distribution density of the circular sub-areas not covered with the metal film layer in area 2230 is lower than the distribution density of the circular sub-areas not covered with the metal film layer in area 2220. The coating coverage ratio of region 2240 is 100%. Fig. 22 In the embodiment, the circular sub-regions not covered by the metal film layer at the same level are horizontally distributed to facilitate the passage of high-frequency narrow beams.

[0104] In an exemplary embodiment, the surface of the coated glass includes a plurality of regions divided in the vertical direction and extending in the horizontal direction. The coating coverage areas of the plurality of regions are alternately distributed in fixed and different proportions; or, are distributed in sequence in gradually changing and different proportions.

[0105] In the embodiments of the present disclosure, the area ratio of the area not covered by the metal film layer (i.e., the film coverage ratio) is different in areas at different levels. Whether the film coverage ratio increases or decreases with the level is not limited in the present disclosure. It can be alternating between two fixed ratios, for example Fig.13 , Fig.14 , Fig.15 , Fig.17 ; It can also be a gradient ratio, for example Fig.19 , Fig. 20 , Fig.21 , Fig. 22 , Fig.23 , Fig.24 .

[0106] In an exemplary embodiment, the surface of the coated glass includes multiple areas divided in the vertical direction and extended in the horizontal direction; the area ratio of the sub-area with the metal film layer and the sub-area without the metal film layer in the same area is fixed; the area ratio of the sub-area with the metal film layer and the sub-area without the metal film layer in adjacent areas is different.

[0107] In the embodiment of the present disclosure, for a horizontal bar area (for example, Fig.29 As shown, a set of sub-areas with a center height of a in the area), wherein the ratio of coated and uncoated sub-areas is required to be fixed, and the ratio of coated and uncoated sub-areas in adjacent different horizontal stripes is different, but the specific ratio value is not limited.

[0108] In an exemplary embodiment, the surface of the coated glass includes multiple areas divided in the vertical direction and extended in the horizontal direction; the relative positions of sub-areas without the metal film layer in different areas are not exactly the same; or, the sub-areas without the metal film layer in the same area are arranged from top to bottom: uniformly; staggered uniformly; annularly uniformly; the sub-areas without the metal film layer in the same area are arranged from top to bottom: annularly uniformly; staggered uniformly; uniformly arranged; staggered uniformly; annularly uniformly distributed.

[0109] For example, Fig.23In the embodiment, the surface of the coated glass 2300 is divided into four areas extending in the horizontal direction from top to bottom. Area 2310 includes a plurality of circular sub-areas not covered with a metal film layer in four horizontal rows, and the circular sub-areas are approximately uniformly distributed in the area 2310 (except for the edge portion). Area 2320 also includes a plurality of circular sub-areas not covered with a metal film layer in four horizontal rows, and the circular sub-areas are approximately staggered and uniformly distributed in the area 2210 (except for the edge portion). The distribution density of the circular sub-areas not covered with a metal film layer in area 2320 is lower than the distribution density of the circular sub-areas not covered with a metal film layer in area 2310. Area 2330 also includes a plurality of circular sub-areas not covered with a metal film layer, and the circular sub-areas are approximately uniformly arranged in a ring shape in the area 2230 (except for the edge portion). The distribution density of the circular sub-areas not covered with a metal film layer in area 2330 is lower than the distribution density of the circular sub-areas not covered with a metal film layer in area 2320. The coating coverage ratio of region 2340 is 100%. Fig.23 In the embodiment, the circular sub-regions not covered by the metal film layer at the same level are horizontally distributed to facilitate the passage of high-frequency narrow beams.

[0110] For example, Fig.24 In the embodiment, the surface of the coated glass 2400 is divided into 7 areas extending in the horizontal direction from top to bottom. The ratio of the coating coverage area of ​​area 2410 and area 2470 is 100%. Area 2420 and area 2460 include multiple circular sub-areas not covered with the metal film layer, and the circular sub-areas are arranged uniformly in an approximately circular shape in area 2420 and area 2460 (except the edge portion). Area 2440 includes multiple circular sub-areas not covered with the metal film layer in two horizontal rows, and the circular sub-areas are approximately uniformly distributed in area 2440 (except the edge portion). Area 2430 and area 2450 also include multiple circular sub-areas not covered with the metal film layer in two horizontal rows, and the circular sub-areas are approximately staggered and uniformly distributed in area 2430 and area 2450 (except the edge portion). The distribution density of the circular sub-areas not covered with the metal film layer is the highest in area 2440, and then decreases in the upper and lower areas. Fig.24 In the embodiment, the circular sub-regions not covered by the metal film layer at the same level are horizontally distributed to facilitate the passage of high-frequency narrow beams.

[0111] like Fig.25 As shown, assuming Fig.24 The coating ratios of the coated glass shown are 100%, 70%, 50%, 20%, 50%, 70%, and 100% from top to bottom, that is, the coating ratio of the middle area 2440 is the lowest. Fig.25The energy distribution of the beams shown on the right corresponds to that of the horizontal beam in the middle, that is, the energy of the horizontal beam in the middle is the most concentrated or the strongest, and can just pass through the uncovered sub-area in area 2440. Fig.25 The hole area distribution like the one on the left matches the signal energy distribution on the right, which can enhance the beam penetration with narrowed vertical beam width.

[0112] In an exemplary embodiment, the surface of the coated glass includes at least two areas divided in the vertical direction and extending in the horizontal direction, and the coating coverage area ratio of at least one of the areas extending in the horizontal direction is 0. This is conducive to the passage of horizontal beams, and the horizontal beams can pass through the horizontal strip extending in the horizontal direction with the coating coverage area ratio of 0. For example, installing the coated glass on the window of a car, that is, the coated glass includes a horizontal area across the entire window, and the coating coverage area is 0% (no coating), which can enhance the penetration under the narrowing of the vertical beam width.

[0113] like Fig.26 As shown, the surface of the coated glass 2600 is divided into 6 areas extending in the horizontal direction from top to bottom. The coating coverage area of ​​areas 2610, 2630, and 2650 is 0% (no coating), which can enhance the penetration under the narrowing of the vertical beam width. The coating coverage area of ​​areas 2620, 2640, and 2660 increases successively until 100%. The sub-areas covered with the metal film layer are all square in shape.

[0114] like Fig. 27 As shown, the surface of the coated glass 2700 is divided into five areas extending in the horizontal direction from top to bottom. The coating coverage area of ​​areas 2710, 2730, and 2750 is 100% (all coated), which is conducive to maintaining the coating effect of the coated glass. The coating coverage area of ​​areas 2720 and 2740 increases successively, that is, the area of ​​the square sub-area not covered with the metal film layer decreases from top to bottom. And the square sub-areas not covered with the metal film layer at the same horizontal height are arranged horizontally, which can enhance the penetration when the vertical beam width is narrowed.

[0115] like Fig.28As shown, the surface of the coated glass 2800 is divided into 12 areas extending in the horizontal direction from top to bottom. The coating coverage area of ​​areas 282, 284, 286, 288, 2810, and 2812 is 100% (all coated), which is conducive to maintaining the coating effect of the coated glass. The coating coverage area of ​​areas 281 and 2813 is 0% (no coating) and is distributed in horizontal strips, which can enhance the penetration under the narrowing of the vertical beam width. The area of ​​the square sub-area without a metal film layer in area 287 is the largest, followed by areas 285 and 289, and then areas 283 and 2811, that is, the area of ​​the square sub-area without a metal film layer in areas 283 and 2811 is the smallest. And the square sub-areas not covered with metal film layers at the same horizontal height are arranged horizontally, which can further enhance the penetration under the narrowing of the vertical beam width.

[0116] In the disclosed embodiment, by alternating the non-coated area with the coated area, and the area of ​​the non-coated area is smaller than the coated area; or by alternating the area with a low coating ratio with the area with a high coating ratio, on the one hand, it is beneficial to the passage of horizontal beams; on the other hand, it is minimized to affect the coating effect of the coated glass itself. In addition, the non-coated sub-areas at the same level are horizontally distributed, which is also beneficial to the passage of horizontal beams.

[0117] According to the above Figures 7 to 28 It can be seen from the embodiments that the embodiments of the present disclosure can be used to achieve a specific coating ratio on the surface of the coated glass by dividing the regions and sub-regions, designing the shapes and sizes of the regions and sub-regions, and whether the regions and sub-regions are covered with a metal film layer.

[0118] Above Fig.19 and Fig.26 It can be a metal film layer attached to the glass body; Fig. 20 , Fig.21 , Fig. 22 , Fig.23 , Fig.24 , Fig. 27 and Fig.28 The method may be to punch holes in the metal film layer covering the glass body, that is, to remove the circular or square metal film layer.

[0119] Above Figures 7 to 28 Taking into account the narrowing of the vertical beam width, the coating coverage ratio is adjusted by the density of the uncoated area / sub-area. Fig.30 and Fig.31As shown, the energy distribution of the signal in the horizontal and vertical directions is different (the energy in the vertical direction decreases faster than in the horizontal direction). From the perspective of improving the efficiency of energy passing through a unit area, the disclosed embodiment uses this factor to increase the overall signal energy that can be transmitted through the vehicle window / building exterior wall glass. Therefore, the shape and penetration ability of the low-coating area are kept consistent with the distribution of the high-energy area of ​​the signal.

[0120] like Fig.30 As shown in the figure, for the same antenna port, the corresponding antenna elements are generally arranged vertically. Therefore, using high frequencies and increasing the number of vertical elements will make the beam form a narrower beam in the vertical dimension. In the horizontal direction, due to the change in antenna width and the number of horizontal elements per antenna port, as well as the change in the number of antenna ports used, the horizontal distribution of beam energy is more uniform than the vertical distribution, forming a more concentrated horizontal beam. This trend will become more obvious as the frequency increases.

[0121] From the receiving side (e.g., a mobile phone in a car or building), the high energy area of ​​the beam can penetrate more through the horizontal long strip area than other shaped areas. Taking the application of coated glass to automobiles as an example, the width of the window itself is greater than the height. According to the arrangement of the non-filmed sub-areas or non-filmed areas provided in the above embodiments, the space utilization rate of the penetrable area of ​​the horizontal beam is higher.

[0122] The coated glass provided in the embodiments of the present disclosure targets the deployment trend of high-frequency signals and takes into account the increase in glass penetration loss of high-frequency signals. By dividing the regions and sub-regions, and whether metal film layers are set in the regions and sub-regions, the coating coverage density of the coated glass can be finely adjusted according to the frequency points of the authorized spectrum in the region / country (difference in penetration loss). The design method and coated glass provided in the embodiments of the present disclosure consider the coverage density of the entire glass surface area, rather than just whether a local area is coated. In addition, the planning of the coated areas / sub-regions provided in the embodiments of the present disclosure is specially optimized for horizontal beams, that is, in the horizontal direction, areas with lower coating density are arranged along the horizontal direction.

[0123] In an exemplary embodiment, the surface of the coated glass is the surface of a piece of glass, or is a spliced ​​surface composed of multiple pieces of glass, or is a discontinuous surface.

[0124] In the embodiments of the present disclosure, the coverage ratio can be determined based on the coating material used for the coated glass (i.e., the material used for the metal film layer) and the considered frequency band (i.e., the communication frequency band, i.e., the frequency band used between network devices and electronic devices). The embodiments of the present disclosure do not limit the specific coating material.

[0125] In an exemplary embodiment, the higher the attenuation of the material of the metal film layer to the communication frequency band, the lower the proportion of the coating coverage area in the region. That is, if the coating material used in the coated glass has a higher attenuation to a certain frequency band, the coating coverage area is lowered to minimize the attenuation of the metal film layer in the coated glass to the frequency band.

[0126] In an exemplary embodiment, the higher the attenuation of the material of the metal film layer to the communication frequency band, the more uncoated sub-regions are included in the coated glass. The uncoated sub-region refers to a sub-region on the glass body of the coated glass where no metal film layer is provided.

[0127] In an exemplary embodiment, the higher the attenuation of the material of the metal film layer to the communication frequency band, the more uncoated areas are included in the coated glass. The uncoated area refers to an area on the glass body of the coated glass where no metal film layer is provided.

[0128] In the embodiment of the present disclosure, the higher the attenuation of the frequency band by the coating material used in the coated glass, the greater the number of uncoated areas and / or uncoated sub-areas in the coated glass, so as to minimize the attenuation of the frequency band by the metal film layer in the coated glass.

[0129] In an exemplary embodiment, the communication frequency band includes a communication frequency band planned to be used in a region or country where the coated glass is used.

[0130] In an exemplary embodiment, the communication frequency band is a frequency band of 6 GHz and above. In the embodiment of the present disclosure, millimeter waves and above are referred to as high frequency bands.

[0131] The disclosed embodiment proposes to change the coating coverage ratio value according to the high-frequency frequency used in the region / country, and a configuration method based on the regional / sub-regional coating coverage pattern corresponding to the ratio. In addition, the disclosed embodiment also proposes an optimization method for the case where the vertical beam width becomes narrower. It is conducive to solving the problem of indoor coverage of operators' high-frequency signals (O2I scenario). It is conducive to solving the problem of in-vehicle signal coverage in a high-frequency coverage environment. It is conducive to improving the number and quality of anchor points for indoor / in-vehicle access signals, and promoting indoor coverage enhancement solutions and D2D (Device to Device) application solutions based on U2N (UE to Network) Relay and P-RAN (Proximity Radio Access Network, a distributed networking technology for 6G).

[0132] Furthermore, an embodiment of the present disclosure also provides a building, including a wall, on which is installed the coated glass as described in any embodiment of the present disclosure, so that a network device located outside the building can communicate with a terminal located inside the building using a communication frequency band or a high-frequency narrow beam.

[0133] The high-frequency narrow beam in the disclosed embodiment refers to an electromagnetic beam with a higher frequency and a narrower beam width. A beam refers to the energy of an electromagnetic wave focused within a certain range to form a smaller area. High frequency means a shorter wavelength, which can carry more information and is suitable for situations requiring high-speed data transmission or high-resolution imaging. A narrow beam width means that the energy is more concentrated, which can improve the reception efficiency of the target signal and reduce the impact of interference and noise, thereby improving the performance of the system. The vertical beam width determines the performance in the range direction in the network coverage area. The narrower the vertical beam width, the more accurately the vertical height of the wireless signal coverage can be controlled by adjusting the antenna tilt angle, which is very helpful in preventing the signal from covering areas that do not need service (for example, avoiding excessive signal coverage of the ground or high floors of buildings).

[0134] Furthermore, an embodiment of the present disclosure also provides a vehicle, on which the coated glass as described in any embodiment of the present disclosure is installed, so that a network device located outside the vehicle can communicate with a terminal located inside the vehicle using a communication frequency band or a high-frequency narrow beam.

[0135] The coated glass provided in the embodiments of the present disclosure can optimize and adjust the glass coating pattern or the coating coverage pattern (i.e., the division of areas and sub-areas, the design of the shape, size, distribution, whether the areas and sub-areas are coated, etc.) according to the frequency band of high-frequency signals used in mobile communication systems, reduce the shielding of the glass coating layer (i.e., the metal film layer) on high-frequency signals, and increase the signal strength that penetrates the glass, thereby optimizing the indoor coverage and in-vehicle coverage of high-frequency signals.

[0136] Fig.32 FIG. 1 is a flow chart of a glass coating method in an exemplary embodiment of the present disclosure. Fig.32 As shown, the method provided by the embodiment of the present disclosure may include the following steps.

[0137] In S321 , the surface of the glass body is divided into different areas.

[0138] In S322, the ratio of the coating coverage area of ​​each region is determined, and the ratios of the coating coverage areas of adjacent regions are different.

[0139] In S323, according to the ratio of the coating coverage area determined for each region, a coating coverage pattern is selected or adjusted for each region so that the ratios of the coating coverage areas of adjacent regions are different.

[0140] In S324, a metal film layer is provided on the surface of the corresponding glass body or the metal film layer on the surface of the corresponding glass body is removed according to the coating covering pattern to form coated glass.

[0141] The ratio of the coating coverage area refers to the ratio of the area of ​​the metal film layer provided on the glass body of the coated glass in the region to the area of ​​the region.

[0142] The glass coating method provided by the embodiment of the present disclosure proposes a method for changing the coating coverage ratio according to the frequency of the high frequency used in the region / country, and a configuration method for the regional / sub-region coating coverage pattern corresponding to the ratio. For example, the number of horizontal regions to be divided can be determined first, and then the coating coverage ratio of each horizontal region can be determined, and then the pattern can be selected or adjusted according to the ratio.

[0143] In an exemplary embodiment, a plurality of sub-regions are distributed in at least one region; a metal film layer is disposed on the glass body in some sub-regions of the same region, and a metal film layer is not disposed on the glass body in the remaining sub-regions.

[0144] In an exemplary embodiment, there is at least one region where the ratio of the coating coverage area is lower than a threshold value, and the center points of the at least one region have the same height and are arranged in the same height horizontal direction along the surface of the coated glass.

[0145] The disclosed embodiment also proposes an optimization method for the narrowing of the vertical beam width. In the disclosed embodiment, for the entire glass surface, there is at least one area with a low coating coverage ratio, the center points of the areas are at the same height, and they are arranged horizontally at the same height on the glass surface, so as to obtain a coating method that can better adjust the balance between the narrow beam's ability to penetrate the glass and the glass coating effect, thereby ensuring the penetration of the narrow beam. That is, the disclosed embodiment provides a glass coating method for improving signal penetration.

[0146] The embodiment of the present disclosure may adopt magnetron sputtering method to prepare coated glass, or adopt vacuum electron beam evaporation method to prepare coated glass. The embodiment of the present disclosure does not limit the specific preparation process.

[0147] The shape of the coated glass in the embodiments of the present disclosure is not limited to the above examples, and the shape of the coated glass can be designed and adjusted according to actual scene requirements.
