Description

Method of manufacturing a transparent electronic banner including a display and power supply unit capable of individual lighting control

The present invention relates to a transparent electronic banner that can naturally become friendly with the surrounding environment without blocking the surrounding landscape by ensuring transparency. More specifically, it improves process costs and product stability by reducing the thickness and weight of the product. This relates to a transparent electronic banner manufactured through an integrated structure using double-sided electrodes.

Various banners made of fabric are installed on roads and city streets for advertising and publicity purposes. In general, a banner is a cloth-shaped screen with various information such as propaganda and slogans written on it so that an unspecified number of people can visually recognize it, and it is installed in a form where both ends are supported by supports such as streetlights or electric poles.

In the case of cloth banners, once they are produced, additional banners must be manufactured to display other advertisements. In other words, a new banner must be produced every time the advertising content is changed, and the process of removing the existing banner and reinstalling a new banner is necessary, which may consume manpower and cost. In addition, since the removed banners cannot be recycled and must be discarded in their entirety, resource efficiency may be low and there is a problem of causing environmental pollution due to waste.

Additionally, these cloth-type banners are less readable at night, lowering information transmission efficiency, and when installed outdoors, they can be easily damaged by the natural environment, damaging the cityscape.

In order to improve the above problems, electronic banners (or electronic signs) using displays have been recently provided. For example, Republic of Korea Patent Publication No. 10-2012-0109281 discloses an advertising system that displays multimedia data or advertising content through an LED display board.

However, in the case of these LED signboards, they are equipped with a PCB (Printed Circuit Board) or FPCB (Flexible Printed Circuit Board) necessary for LED control, and as circuit boards such as PCB or FPCB limit the transparency of the signboard, the LED signboard This could harm the surrounding landscape.

On the other hand, the printed circuit boards for controlling the LEDs can be compressed into the side frame to make the LED display transparent, but in this case, damage to the board or parts may occur due to moisture and temperature in the harsh outdoor environment. As a result, the lifespan of the device is significantly reduced, maintenance costs may continue to arise, and transparency of the frame is still not secured, so it cannot naturally blend into the urban landscape.

Additionally, in the case of electronic banners, significant power consumption costs may occur as power to drive the display is continuously consumed.

Therefore, it is naturally friendly to the surrounding environment without blocking the surrounding landscape, contributing to the improvement of the beautiful cityscape, and is a transparent substrate in a vacuum state that is free from contamination, corrosion of circuit boards such as PCBs and FPCBs, and failure of electronic components in devices installed outdoors. There may be a demand for research and development for transparent displays and transparent electronic banners using them that can reduce after-sales service costs by implementing the structure and reducing operation power consumption through self-generation and energy recycling.

The problem to be solved by the present invention was developed in response to the above-described background technology, and is a transparent electronic banner with an integrated structure utilizing double-sided electrodes to improve process costs and product stability by reducing the thickness and weight of the product.

The transparent electronic banner 100 of the present invention may be an electronic banner for providing various visual information (for example, visual information regarding advertising, publicity, convenience, or safety accident prevention, etc.) to an unspecified number of users. An electronic banner is intended to improve the decrease in efficiency that occurs in the process of using a cloth-type banner, and may refer to a banner that displays images or text in an electronic manner. With these electronic banners, there is no need to remove or reinstall the banner in the process of changing the displayed visual information, and there is no need to dispose of the removed banner, minimizing the consumption of manpower and costs for maintenance. , can prevent environmental pollution. Additionally, electronic banners have the advantage of being highly efficient in conveying information as they are easy to identify even at night.

According to one embodiment, the transparent electronic banner 100 of the present invention may be characterized as having transparency above a certain level. In the case of a general electronic banner (for example, an electronic banner or an electronic billboard, etc.), it may include a PCB or FPCB circuit board for controlling a plurality of LEDs. Generally, circuit boards related to PCBs and FPCBs are provided adjacent to an LED display to control the display of the display. For example, as circuit boards are provided on the back of the display, transparency of the display may be limited. For a specific example, as shown in FIG. 1, looking at the conventional electronic banner 100a supported by the support 10, it cannot have transparency because a circuit board is provided on the back of the display. That is, the surrounding background is completely obscured by the conventional electronic banner 100a. When a plurality of such conventional electronic banners 100a are provided in various locations (e.g., roads, bridges, trails, bus shelters, etc.), the surrounding scenery is obscured by the substrates on the back side, which is a factor that harms the cityscape. It can act as

In addition, in an embodiment, when electronic products containing circuit boards such as PCB or FPCB are used indoors, the stability or sustainability of the device is guaranteed, but when installed outdoors, they are exposed to large temperature changes, rain, snow, and wind. Depending on the influence of various environmental factors, failure of the board or components can easily occur. For example, moisture can cause device failure by contaminating or corroding PCB and FPCB circuit boards.

According to one embodiment of the present invention, as shown in FIG. 1, the transparent electronic banner 100 may be provided with transparency above a certain level so that the rear part of the device can be identified by transmitting the background. In other words, the transparent electronic banner 100 can contribute to improving the beautiful cityscape by naturally becoming friendly with the surrounding environment without blocking the surrounding scenery. In other words, the present invention can provide an aesthetically transparent electronic banner that does not obscure the surrounding landscape. For example, it is possible to create a cutting-edge city image suitable for a smart city by creating a mysterious yet luxurious feeling, as if lights are floating in the air.

In a specific embodiment, the transparent electronic banner 100 of the present invention can implement a transparent display by constructing a display without using a PCB and FPCB circuit board required for LED control.

Since the transparent electronic banner 100 does not include a PCB or FPCB circuit board that is vulnerable to temperature changes and moisture, it has the advantage of ensuring improved stability of the device even in an outdoor environment and reducing maintenance costs.

Additionally, the transparent electronic banner 100 of the present invention converts solar energy into electrical energy during the day and uses this to emit a light source (i.e., LED) to display visual information, and at night, street lamps, car headlights, or light sources The light emitted through this can be used to collect electricity and be reused to form a virtuous cycle of energy. In other words, since electrical energy can be independently acquired and supplied based on light energy, the power supply cost for displaying the display can be minimized. In other words, the transparent electronic banner 100 has the advantage of saving energy as it can collect current for 24 hours.

Hereinafter, with reference to FIGS. 2 to 17, in order to ensure transparency and stability, a method of implementing a transparent electronic banner 100 without a PCB and FPCB circuit board for LED control and the effects caused thereby will be described in detail. do.

According to one embodiment, the transparent electronic banner 100 may include a transparent display unit 110 and a power supply unit 120. The above-described components are exemplary and the transparent electronic banner of the present invention is not limited to the above-described components. That is, depending on the implementation aspect of the embodiments of the present invention, additional components may be included, or at least some of the above-described components may be omitted.

The transparent display unit 110 serves to display visual information, and the power supply unit 120 serves to supply power to the transparent display unit 110. According to one embodiment, the power supply unit 120 of the present invention may be implemented using a dye-sensitized solar cell.

According to one embodiment, the power supply unit 120 may include a solar cell that converts light energy into electrical energy. The power supply unit 120 of the present invention may refer to a solar cell that converts light energy to obtain electrical energy. Electrical energy obtained through solar cells is supplied to the transparent display unit 110, allowing light to be expressed through a plurality of LED pixels.

In an embodiment, the solar cell may include a dye-sensitized solar cell (DSSC). As an example, a dye-sensitized solar cell may be a solar cell that operates through a principle similar to the photosynthetic principle of plants.

Specifically, dye-sensitized solar cells operate on the principle that special dye molecules chemically adsorbed on the surface of metal oxide absorb light to generate electrons, and collect the generated electrons at the electrode to produce electrical energy. In an embodiment, dye-sensitized solar cells can be provided transparently using transparent dyes or in various colors using dyes of various colors, making them highly versatile.

Because these dye-sensitized solar cells have a relatively simple structure, their manufacturing cost is only 20 to 50% of that of silicon-based solar cells. In addition, dye-sensitized solar cells have the advantage that there is almost no decrease in efficiency depending on the angle of incidence of light and that the power generation during the day and night is higher than that of other solar cells. In other words, in the case of dye-sensitized solar cells, there is almost no decrease in efficiency depending on the angle of incidence, so they do not need to be installed in the direction where sunlight is incident, so they have high autonomy and flexibility in where they are installed, and even when there is no sun, It has the advantage of generating electrical energy based on various light energies (for example, car headlights, light emitted from LEDs, or street lamps, etc.).

In the case of the transparent electronic banner 100 of the present invention, in order to ensure overall transparency of the device, it may be provided including a power supply unit 120 composed of a dye-sensitized solar cell.

As the solar cell included in the transparent electronic banner 100 of the present invention is implemented through a fuel-sensitive solar cell, it collects electrical energy through sunlight during the day and collects vehicle headlights, street lights, and LED light at night. By doing so, electrical energy can be continuously obtained and supplied to the transparent display unit 110 even at night when there is no sun. In particular, light energy emitted from a plurality of LED pixels of the transparent display unit 110 provided in contact with one side of the fuel-sensitive solar cell can be recycled into electrical energy, thereby realizing a virtuous cycle of energy. You can.

According to an embodiment, the transparent electronic banner 100 may include a transparent display unit 110 including a plurality of pixels. The transparent display unit 110 may include a plurality of pixels and may display visual information by controlling lighting of the plurality of pixels.

For example, as shown in FIG. 2, the transparent display unit 110 lights up at least some of the plurality of pixels to express the current time (e.g., 3:04) in text form to provide visual information. Alternatively, visual information may be provided by expressing the current weather (e.g., rain) in the form of a picture. The visual information included in FIG. 2 is only an example, and various forms of visual representation of various information (e.g., emergency disaster information, forward accident information, advertising information, weather information, local public information, etc.) are provided more than the display device of the present invention. It will be obvious to those skilled in the art that it can be provided through . For example, the transparent display unit 110 can provide a dynamic visual expression, such as text moving in one direction or movement being given to an object, through gradual lighting between a plurality of pixels. For another example, the transparent display unit 110 may display more vivid objects or characters by lighting each pixel in various colors.

The transparent display unit 110 included in the transparent electronic banner 100 of the present invention is in the form of a single module in which each light-emitting module is implemented with one LED pixel, and in the form of a combined module in which each light-emitting module is implemented with a plurality of LED pixels ( That is, it can be implemented through at least one of strip type and wire mesh type) and film form.

Since both the transparent display unit 110 and the power supply unit 120, which constitute the transparent electronic banner 100 of the present invention, are transparent, it can naturally be friendly to the surrounding environment without blocking the surrounding scenery. For example, it is possible to create a cutting-edge city image suitable for a smart city by creating a mysterious yet luxurious feeling, as if lights are floating in the air. Also, for example, during the day when no visual information is displayed, it appears like transparent ordinary glass and does not harm the surrounding scenery.

According to one embodiment of the present invention, the transparent display unit 110 and the power supply unit 120 may each be provided in shapes corresponding to each other.

Meanwhile, the transparent electronic banner of the present invention can be implemented by bonding the transparent display unit 110 and the power supply unit 120 with each other facing backwards. That is, as shown in (a) of FIG. 3, the transparent electronic banner 100 can be implemented through a bonding process between the power supply unit 120 that supplies power and the transparent display unit 110 that displays visual information. there is.

For a specific example, after the transparent display unit 110 and the power supply unit 120 are produced through individual manufacturing processes, the transparent electronic banner 100 may be created through a bonding process of each glass film. That is, the transparent display unit 110 and the power supply unit 120 can be integrated through a bonding process between the glass films.

However, as described above, when the transparent display unit 110 and the power supply unit 120 are manufactured separately and bonded through a glass film bonding process, each component (transparent display unit and power supply unit) is made of two glass films separately. It must be included.

In more detail, when the transparent display unit 110 and the power supply unit 120 are manufactured separately, the transparent display unit 110 and the power supply unit 120 are each spaced a certain distance apart from each other as shown in (b) of FIG. 3. It is composed of two glass films, and includes elements (eg, photoelectrodes, LED pixels, electrodes, resin or fillers, etc.) between the glass films.

That is, the transparent display unit 110 and the power supply unit 120 each include two glass films, and as a result, the glass film produced through the bonding process between the transparent display unit 110 and the power supply unit 120 In the case of the transparent electronic banner 100, it is composed of a total of four glass films.

In this way, when a transparent electronic banner is implemented through four glass films, the process cost increases as more glass films are required, and the thickness and weight of the product increase. This may reduce the stability of electronic banner products that are mainly installed in high locations (e.g., approximately 2 m or higher).

In order to solve the problems such as increase in process cost and decrease in stability as described above, the present invention performs a process of forming a transparent display unit 110 and a power supply unit 120 on each of both sides based on a single glass film. A transparent electronic banner 100 can be implemented.

As shown in FIG. 4, when the transparent display unit 110 and the power supply unit 120 are formed on each of both sides by sharing a single glass film, the transparent display unit 110 and the power supply unit 120 are manufactured separately. Since the overall number of glass films used can be reduced compared to the manufacturing method of bonding, the production cost can be lowered.

According to a specific embodiment, the transparent electronic banner 100, as shown in FIG. 5, has a total of three glass films as the transparent display unit 110 is formed based on the glass film constituting one side of the power supply unit 120. (That is, it may be characterized as including a surface glass film 111, a glass film 100-1, and a battery glass film 121). Generally, the transparent electronic banner 100 (or electronic banner) is provided at a high place so that multiple users can see it. For example, the transparent electronic banner 100 may be installed on a support such as a streetlight or electric pole. In the case of the transparent electronic banner 100 of the present invention, both the power supply unit 120 and the transparent display unit 110 are transparent and are provided to include only three glass films, so they can be implemented with relatively low weight and thin thickness. Therefore, it can blend more naturally into the surrounding landscape, and can be more stably coupled to the support through lightening.

In this way, as less glass film is included, the thickness and weight of the finally manufactured transparent electronic banner 100 can be reduced, and the stability of the electronic banner installed at a high place can be improved. In other words, it can provide the effect of improving the commercial viability and safety of the product by increasing process efficiency, reducing weight, and increasing durability.

Meanwhile, when performing a process of manufacturing the power supply unit 120 and the transparent display unit 110 on each of both sides based on a single glass film, the stability of the transparent electronic banner 100 manufactured is affected by the influence between each process. may deteriorate.

Specifically, the solar cell corresponding to the power supply unit 120 in the present invention requires high temperature during the manufacturing process. For example, in the case of a dye-sensitized solar cell, a high temperature of approximately 500°C may be required during the sintering process to form a photoelectrode, and this high temperature of 500°C may be applied to the transparent display unit (provided behind the dye-sensitized solar cell). 110). For example, in the case of the transparent display unit 110, the light emitting module can be fixed through a bonding material (eg, resin or film). However, under the influence of the high temperature of 500°C required for sintering the photoelectrode on the opposite side, the bonding material made of resin melts and the light emitting module is not fixed and comes off, or the interior of the transparent display unit 110 is not maintained in a vacuum state. It may not be possible. Accordingly, the process for the display unit integrating the LED and the process for forming the solar cell cannot proceed at the same time.

Therefore, in the process of creating the transparent display unit 110 and the power supply unit 120 based on a single glass film, it is very important to specifically plan the process sequence and process method so as not to be affected by both processes.

Hereinafter, in the process of manufacturing the display unit and the power supply unit on each of both sides based on a single glass film, specific process methods and process sequences to avoid influence between each process will be described in detail.

Figure 6 is an exemplary diagram illustrating a transparent electronic banner related to an embodiment of the present invention. The order of the steps shown in FIG. 6 may be changed as needed, and at least one step may be omitted or added. The steps in Figure 6 are only one embodiment of the present invention, and the scope of the present invention is not limited thereto.

According to an embodiment of the present invention, a method of manufacturing a transparent electronic banner may include preparing a glass film 100-1 (S110). The glass film 100-1 is provided between the transparent display unit 110 and the power supply unit 120. The transparent display unit (100-1) is provided between the surface glass film 111 of the transparent display unit 110 and the glass film 100-1. Elements constituting the power supply unit 110 are provided, and elements constituting the power supply unit 120 are provided between the battery glass film 121 and the glass film 100-1 of the power supply unit 120. The glass film 100-1 may refer to a surface shared by the transparent display unit 110 and the power supply unit 120 and a surface that separates each component. The glass film 100-1 is preferably made of a material having mechanical strength above a certain level in order to protect internal electronic devices from impact. In an embodiment, the glass film may be provided through non-tempered glass, that is, normal glass, but is not limited thereto.

According to one embodiment of the present invention, the method of manufacturing a transparent electronic banner includes the steps of manufacturing a transparent electronic banner by performing a process of forming each of the transparent display unit 110 and the power supply unit 120 corresponding to each of both sides of the glass film ( S120) may be included.

Specifically, the transparent electronic banner 100 may be produced through a method of forming a dye-sensitized solar cell (i.e., a power supply unit) and a transparent display unit respectively on one side and the other side of the glass film. there is.

That is, a dye-sensitized solar cell (DSSC) may be provided as the power supply unit 120 to be in contact with the transparent display unit 110. In this case, as described above, the transparent electronic banner 100 may be provided including three glass films.

According to one embodiment, the process of forming each of the transparent display unit 110 and the power supply unit 120 corresponding to each of both sides of the glass film includes forming a power supply unit on one side of the glass film, and then forming the transparent display unit 110 and the power supply unit 120 on one side of the glass film. It may be characterized in that a process for forming the display unit is performed.

Specifically, the solar cell corresponding to the power supply unit 120 in the present invention requires high temperature during the manufacturing process. For example, in the case of a dye-sensitized solar cell, a high temperature of approximately 500°C may be required during the sintering process to form a photoelectrode, and this high temperature of 500°C may be applied to the transparent display unit (provided behind the dye-sensitized solar cell). 110). For example, in the case of the transparent display unit 110, the light emitting module can be fixed through a bonding material (eg, resin or film). However, under the influence of the high temperature of 500°C required for sintering the photoelectrode on the opposite side, the bonding material made of resin melts and the light emitting module is not fixed and comes off, or the interior of the transparent display unit 110 is not maintained in a vacuum state. It may not be possible. Accordingly, the power supply unit 120 manufacturing process that requires a relatively high temperature (e.g., 500°C) is first performed on one side of the glass film 100-1, and then a relatively low temperature (e.g., 500°C) is performed on the other side of the glass film 100-1. For example, a manufacturing process for the transparent display unit 110 that requires 120°C may be performed.

On the other hand, since the solar cell manufacturing process requires a higher temperature, the solar cell manufacturing process must be performed first, but the opposite side of the glass film 100-1 (i.e., the display) is affected by the pressure generated during the solar cell manufacturing process. Damage may occur to the side provided.

For example, in the process of manufacturing a dye-sensitized solar cell, pressure may be applied to the other side of the glass film and damage it during the process of printing an FTO pattern or printing an electrode (e.g., a pressure screen printing process, etc.).

Accordingly, in the process of manufacturing the power supply unit 120 on one side of the glass membrane, it is very important to protect the surface of the opposite side of the glass membrane.

The present invention may be characterized by providing a protection stand 200 to prevent damage to the other side of the glass film 100-1 during the process of forming the power supply unit on one side of the glass film 100-1. . The protection holder 200 is in contact with the other side of the glass film 100-1 on which the transparent display unit 110 is formed, and serves to prevent damage to the other side of the glass film 100-1 from pressure. The protection holder 200 may be provided in contact with one surface of the glass film 100-1 or separated from it depending on each process step during the process of forming the power supply unit 120.

In one embodiment, the protection holder 200 may be configured to include a substrate 210, a plurality of pad portions 220, and a handle portion 240, as shown in FIG. 7. The above-described components are exemplary, and the protective stand of the present invention is not limited to the above-described components. That is, depending on the implementation aspect of the embodiments of the present invention, additional components may be included, or at least some of the above-described components may be omitted.

According to an embodiment, the protection holder 200 may include a substrate 210 made of a ceramic material. The substrate 210 is implemented in the shape of a plate so that the glass film 100-1 can be mounted.

The protection holder 200 is attached to the other side of the glass film 100-1 in response to the process in which the solar cell is formed on one side of the glass film 100-1 to protect the surface of the glass film 100-1. It plays a role. However, processes performed on one side of the glass film 100-1 (eg, electrode pattern formation and photoelectrode sintering processes, etc.) may be high-temperature and high-pressure processes. Accordingly, the substrate 210 is preferably made of a ceramic material that is resistant to high temperatures and pressures. Ceramic materials are resistant to heat/temperature changes. In a specific embodiment, the substrate 210 may be implemented using silicon-based rubber with heat resistance of over 500°C, oxide-based ceramic material (Al2O3, ZrO2, etc.), or lithia porcelain (Li2O-Al2O3-xSiO2). .

For example, when the glass film 100-1 is mounted using tempered glass, which has good durability, the tempered glass is damaged as the temperature drops rapidly during the dye adsorption process after the high-temperature light sintering process. Therefore, the present invention is characterized by constructing the substrate 210 of the protection stand 200 using a ceramic material that is resistant to heat and temperature changes.

In various embodiments, one surface of the substrate 210 may include a pad insertion groove 211 into which a portion of the pad portion 220 is inserted. As shown in FIGS. 8 to 10, pad insertion grooves 211 may be formed corresponding to a plurality of regions of the substrate 210, and each of a plurality of pads is inserted corresponding to the pad insertion groove 211. It is a composition that is combined.

The pad insertion groove 211 may be provided in the shape of a groove having a preset height. Here, the preset height may mean a height smaller than the height of the pad portion. As the height (or depth) of the pad insertion groove 211 is smaller than the height of the pad portion 220 fitted and coupled to the corresponding pad insertion groove 211, only a portion of the pad portion 220 is inserted into the pad insertion groove 211. is inserted into the surface, and the other part is exposed to the outside in a protruding form from the surface. The pad insertion groove 211 is configured to improve the bonding force between the pad portion 220 and the substrate 210. For example, when the pad portion 220 is attached to the substrate 210 using an adhesive without a separate groove, the protruding pad portion may be exposed to the applied pressure during the process of applying pressure to the protection holder 200. It can be easily separated from the substrate 210. When the pad portion 220 is separated, the protection holder 200 cannot support the glass membrane 100-1 more firmly and safely. This causes a decrease in process stability and quality.

That is, in the present invention, a groove having a certain depth, that is, a pad insertion groove 211, is formed in the substrate 210, and each of a plurality of pad parts is inserted and fixed corresponding to each of the pad insertion grooves, even under various pressures. Ensure that each pad portion is firmly attached to the substrate.

Additionally, according to the embodiment, the protection holder 200 is made of a flexible material and may include a plurality of pad portions 220 provided on one surface of the substrate 210. As shown in FIGS. 9 and 10, the plurality of pad parts 220 are parts that directly contact one surface of the glass film 100-1. That is, the substrate 210 supports the glass film 100-1 via the pad portion 220.

In the case of the pad portion, it is provided with soft, ductile silicone rubber to minimize damage to the glass film 100-1 that comes into contact with it. In the case of silicone rubber, it can have heat resistance corresponding to high temperatures of 500°C or higher. In other words, it is desirable to construct the pad portion using silicone rubber that has strong heat resistance and soft ductility.

In an embodiment, the plurality of pad portions 220 may be provided on one surface of the substrate 210 and may be provided to have a certain pattern. Here, the constant pattern is intended to support the glass film 100-1 more stably in response to various areas of the substrate 210 while minimizing the contact area with the glass film.

In a specific embodiment, the plurality of pad parts 220 correspond to each of the first pad part 221 formed at the center of the substrate 210 and a plurality of sides included in the substrate, as shown in FIG. 7. It may include a second pad portion 222 formed and a third pad portion 223 formed corresponding to each of a plurality of corners included in the substrate. That is, the plurality of pad parts 220 of the present invention may be provided in a pattern in the side area and the central area for the center of gravity to minimize the contact area with the glass film.

In an embodiment, the plurality of pad parts 220 may be provided so as not to contact each other, thereby forming a circulation passage 230 between each pad part. The circulation passage 230 serves as a passage for circulating air during a high temperature process. For example, if the circulation passage 230 is not provided, high-temperature gas cannot be discharged from the inside of the pad portion 220 during the high-temperature sintering process. In this case, vibration may occur in the glass film 100-1 due to pressure generation through high-temperature gas, which may interfere with the process light well. In severe cases, it may accelerate the separation of the pad portion 220 or accelerate the separation of the glass film 100-1. 1) It may cause damage to itself. Accordingly, the pad portion 220 may be patterned and provided to form the circulation passage 230.

In an embodiment, with a portion of the pad portion 220 inserted into the pad insertion groove 211 formed in the substrate 210, the pad portion is coupled to one surface of the substrate 210 through a bonding process using a curing agent. It can be. Describing in detail with reference to FIG. 8 , the pad portion 220 is inserted into the pad insertion groove 211 in a state in which a curing agent is applied to the pad insertion groove 211. Accordingly, the lower area 211b of the pad portion 220 comes into contact with the pad insertion groove 211. In this case, a curing agent is applied to the pad insertion groove 211, and based on this, the pad portion 220 and the pad insertion groove 211 are bonded using a simple curing agent. In specific embodiments, bonding may be performed using a SiCH _x O _y based ultra-high temperature silicone curing agent. According to this coupling process, the pad portion 220 can be provided by being coupled to the pad insertion groove 211.

Additionally, in an embodiment, the curing process may be performed corresponding to the side surface of the pad portion 220 protruding from one surface of the substrate 210. As shown in FIG. 8, a curing process is performed corresponding to the side area 211a of the pad portion 220.

Performing a curing process on the side of the pad portion 220 protruding from the substrate 210 may be to control the vertical strain rate of the pad portion 220.

More specifically, referring to FIG. 10 , the pad portion 220 is provided between the substrate 210 and the glass film 100-1 and serves to support the other side of the glass film 100-1. In this case, a screen printing process may be performed on one side of the glass film during the process of forming electrodes for forming solar cells. That is, an electrode is formed on one side of the glass film 100-1 through a screen printing process. During the screen printing process, the printing material flows in and is coated according to the pattern to form an electrode. Because this screen printing process automatically adjusts spacing, pressure, and speed increase, it is important that the height of the glass film remains constant. However, in the case of the pad part 220 of the present invention, it is made of a soft, flexible material (e.g., silicone rubber) in order to minimize damage to the glass film in contact, and the pad part 220 made of such a soft material is formed on the upper part. It can be easily changed by pressure applied from any direction. Accordingly, when pressure according to the printing process is applied to a specific upper area, the pad portion 220 provided through the soft material easily sinks, causing a change in height, and errors occur during the printing process according to the change in height. I do it. This acts as an error in forming electrodes through unintended height, thickness, and spacing.

Therefore, in order to minimize the change in height according to the pressure of the pad portion 220 of the present invention, that is, the vertical strain rate, the curing process may be performed in response to the protruding side area 211a. Through the curing process using a curing agent, the pad portion 220 is prevented from being depressed, i.e., vertically deformed, and the glass film can be supported at a constant height even during the printing process. In particular, the upper surface of the pad portion 220, which is in direct contact with the glass film, has soft ductility as no separate hardening treatment is performed, thereby minimizing damage to the surface of the glass film 100-1. I can support it.

Additionally, according to an embodiment, the protection holder 200 may include a handle portion 240 extending from one end of the substrate 210. The handle portion 240 may be an area that a user can clamp to facilitate movement while the glass film 100-1 is loaded on the protection holder 200 (i.e., the substrate). For example, depending on the situation, the handle portion 240 may be held to load the glass membrane 100-1 onto the protective holder 200, or the protective holder 200 may be separated from the glass membrane 100-1. Through this handle portion 240, the protection holder 200 can be easily attached and detached during the process, thereby improving convenience.

Additionally, in an embodiment, the step of manufacturing a transparent electronic banner corresponding to each of both sides of the glass film may include a step (S210) of contacting the protective holder 200 with the other side of the glass film, as shown in FIG. 11. .

The process for the power supply unit (e.g., dye-sensitized solar cell) that requires a relatively high sintering temperature must be performed first, and the pressure generated during the manufacturing process of the power supply unit 120 must be applied to the opposite side of the glass film (i.e. , the other side) is provided with a protection stand 200 to protect it. That is, a process of manufacturing the power supply unit 120 on one side of the glass film 100-1 may be performed while the other side of the glass film is loaded on the protection holder 200.

In addition, the step of performing the process of forming each of the transparent display unit 110 and the power supply unit 120 in response to each of both sides of the glass film includes forming a photoelectrode on one side of the glass film 100-1 (S220). It can be included.

Referring to FIG. 12, forming a photoelectrode may include forming a transparent electrode pattern on one side of the glass film while a protective holder is in contact with the other side of the glass film (S221). For example, a transparent electrode pattern may mean a Fluorine-doped Tin Oxide (FTO) pattern.

Additionally, in an embodiment, forming a photoelectrode on one surface of the glass film may include temporarily removing the protection holder 200 to perform washing and drying (S222). During the process of washing and drying the glass film on which the transparent electrode pattern is formed, the protective holder 200 is temporarily removed.

Additionally, in an embodiment, the step of forming a photoelectrode on one side of the glass film may include the step of contacting the protective support again with the other side of the glass film on which the transparent electrode pattern is formed on one side (S223). After the washing and drying process, the glass film on which the transparent electrode pattern is formed is loaded again onto the protection holder 200. That is, the protection holder 200 comes into contact with one side on which the transparent electrode pattern is formed and the other side corresponding to the other side. The purpose of using the protection stand 200 again after the washing and drying process is to protect the other side on which the transparent display unit 110 is formed during the subsequent process.

Also, in an embodiment, forming a photoelectrode on one side of the glass film may include printing an electrode on one side of the glass film on which the FTO substrate pattern is formed and performing TiO ₂ coating (S224). According to examples, TiO ₂ is widely used as a photoelectrode material because it has a high internal surface area, ease of manufacture, and chemical stability. Dye molecules chemically adsorbed on the TiO ₂ surface of the photoelectrode receive light and generate electrons. In embodiments, TiO ₂ may be coated through various processing methods such as doctor blade, spin coating, and screen printing.

Additionally, in an embodiment, forming a photoelectrode on one surface of the glass film may include forming the photoelectrode by sintering TiO ₂ (S225). In a specific embodiment, TiO ₂ paste is coated on the second side of the FTO glass using a doctor blade method after tape casting, and then sintered at a temperature of 500°C for a certain period of time (eg, 60 minutes).

Additionally, in an embodiment, forming a photoelectrode on one surface of the glass film may include adsorbing a dye to the photoelectrode with the protective holder 200 removed again (S226). For example, after the photoelectrode is formed, cooling may be performed in an electric furnace to a certain temperature (e.g., 80°C), and the cooled substrate may be impregnated with dye for a certain period of time (e.g., 24 hours) to allow the dye to adsorb. It can be. In the process of adsorbing the dye to the photoelectrode, the protective holder 200 is removed again. Also, in the embodiment, after adsorption of the dye, the protection holder 200 is used again to protect the other side of the glass film during the bonding process of the photoelectrode and the counter electrode.

Additionally, the step of manufacturing a transparent electronic banner corresponding to each of both sides of the glass film may include bonding a counter electrode corresponding to the photoelectrode (S230).

In an embodiment, the counter electrode may be manufactured through the steps of forming an FTO substrate pattern, creating and injecting an electrolyte inlet into which the electrolyte can be injected, washing and drying, and printing and sintering the counter electrode. The counter electrode manufactured through these steps can be bonded to the photoelectrode.

As an example, Pt paste can be coated on one side of the glass film 100-1 on which the photoelectrode is formed using a doctor blade method after tape casting, and the Pt counter electrode is formed by firing at a temperature of 500°C and then cooling to room temperature.

According to an embodiment, as the bonding of the photoelectrode and the counter electrode is performed through a screen printing process, pressure is applied to the glass film, which may cause damage to the other side of the glass film. The protection holder 200 is used to protect the other side of the glass film 100-1 (i.e., the other side on which the transparent display part is formed) from the pressure generated during the bonding process of the photoelectrode and the counter electrode. It is provided in contact with another surface.

In addition, the step of manufacturing a transparent electronic banner corresponding to each side of the glass film may include removing the protective holder attached to the other side of the glass film after the bonding of the counter electrode is completed (S240). After the process of forming the power supply unit 120 on one side of the glass film is completed, the protection holder 200 is completely removed from the other side of the glass film.

Additionally, the step of manufacturing a transparent electronic banner corresponding to each of both sides of the glass film may include removing the protective holder and then mounting one or more light emitting modules corresponding to the other side (S250). That is, after the production of the positive electrodes (photoelectrode and counter electrode) of the dye-sensitized solar cell is completed, the light emitting module for display is mounted on the circuit of the LED electrode.

In addition, the step of manufacturing a transparent electronic banner corresponding to each of both sides of the glass film may include performing sealing by injecting an electrolyte corresponding to one side after the mounting of one or more light emitting modules is completed (S260). That is, after one or more light emitting modules are completed, electrolyte is injected and sealing is performed, thereby forming the transparent display unit 110 on the other side of the glass film.

The present invention can prevent each of the dye-sensitized solar cell and the transparent display unit 110 from being affected by performance degradation during each production process through the above-described process sequence or process. In other words, the transparent electronic banner 100 of the present invention can be implemented by providing the transparent display unit 110 and the power supply unit 120 (e.g., solar cells) on the back so as not to be affected during each production process.

According to one embodiment of the present invention, the transparent display unit 110 includes a surface glass film 111, a glass film 100-1, one or more light emitting modules 112, and a transparent electrode 113, as shown in FIG. 13. and a bonding material 114.

The transparent display unit 110 may include a surface glass film 111 that forms the outer surface of the transparent display unit 110. In one embodiment, the surface glass film 111 forms the outer surface of the transparent electronic banner 100 and serves to protect electronic devices (eg, LED pixels and electrodes, etc.) provided therein. Since the transparent display unit 110 can be installed outdoors, the surface glass film 111 is preferably made of a material having a mechanical strength of a certain level or higher to protect the internal electronic elements from impact.

According to one embodiment, the surface glass film 111 may be provided through AR (anti-reflective) tempered glass. Because AR tempered glass has high mechanical strength, it is excellent for protecting internal elements from shocks that may occur from the outside, and because it has low reflective power, it has the advantage of being able to provide high information transmission.

In an embodiment, the glass film 100-1 may refer to a surface shared by the transparent display unit 110 and the power supply unit 120 and a surface that separates each component. In FIG. 13, the glass film 100-1 is shown as being related to only one side of the transparent display unit 110, but as in the above description, the glass film is present on the surface corresponding to the surface on which the transparent display unit 110 is formed. The power supply unit 120 may be formed by sharing (100-1).

The glass film 100-1 is preferably made of a material having mechanical strength above a certain level in order to protect internal electronic devices from impact. In an embodiment, the glass film may be provided through non-tempered glass, that is, normal glass, but is not limited thereto.

Additionally, the transparent display unit 110 is provided between the surface glass film 111 and the glass film 100-1, and may include one or more light emitting modules 112 including at least one LED pixel. In one embodiment, the LED pixel may refer to a smart pixel or Micro LED that can be individually controlled.

In an embodiment, each of the one or more light emitting modules may include an individual controller, allowing individual lighting control. That is, the transparent display unit 110 of the present invention may be characterized by not being provided with a separate LED driver for controlling each light-emitting module.

For example, in the case of displays using general LEDs, light is controlled by directly changing the voltage on the LED elements. For example, the light of an LED device can be controlled through voltage related to RGB. In this case, all LEDs on the same line emit the same color. Accordingly, when using general LEDs, a rainbow effect (e.g., an effect in which LEDs display different colors at once) or a wave effect (e.g., a sequential operation effect that causes LEDs to grow sequentially or turn off) Various effects cannot be provided, and as a result, there is a limitation in that the diversity of visual information that can be expressed through the display is limited.

Additionally, a separate LED driver may be required to control multiple LEDs, and this driver is implemented in the form of a PCB. Since this PCB must be provided close to the display (eg, on the side or back), it acts as a factor limiting the transparency of the display.

Accordingly, various effects can be implemented using addressable LEDs (ALED, Addressable LED, or LED pixels) that can be individually controlled through digital signals.

Meanwhile, a plurality of ALEDs may be connected in series to form a loop. In this case, as shown in (a) of FIG. 14, each ALED must use a Zener diode (ZD) as a voltage regulator because the voltage must not change in order to not interfere with data transmission. Additionally, a separate voltage regulator (eg, Zener diode) and a series of capacitors (C) in the line to overcome the ground potential must be provided.

The present invention can provide a current loop interface for implementing ALED (i.e., LED pixel) that can reduce power while completely eliminating voltage regulators such as Zener diodes. In other words, serial data communication between LED pixels is not interrupted, and a current loop interface can be provided that allows a bunch of LED pixels to have flexible energy consumption.

In a more specific embodiment, referring to (b) of FIG. 14, the LED pixels are not directly connected, but a current loop is implemented by interposing a MOSFET between two LED pixels, but GND1 < VDD2 - Uth (of the MOSFET (Q2) In the case of threshold voltage), the circuits of two LED pixels (ALED(U1) and ALED(U2)) can be combined through a current loop. In this case, the source of the MOSFET (Q1) is connected to GND1 of the first LED pixel (U1), the gate is connected to D0, the drain of the MOSFET (Q1) is connected to the gate of the MOSFET (Q2) through the resistor (RG), A resistor (R2) is connected between the gate and source of the MOSFET (Q1), XDD2 is connected to the source of the MOSFET (Q2), and an LED pixel is connected to the drain of the MOSFET (Q1).

In addition, according to an embodiment, a current loop is implemented by interposing a MOSFET between two LED pixels instead of directly connecting the LED pixels. However, if VDD1 > GND2 + Uth, the two LED pixels (ALED(U1) are connected through the current loop. and ALED (U2)) circuits can be combined. The specific details of the current loop interface implementation method for the addressable LED of the transparent display are specifically discussed in Republic of Korea Patent Publication No. 10-2036603, which is incorporated by reference in its entirety in this application.

When utilizing this current loop interface, Zener diodes and voltage regulators can be completely eliminated because data transfer operates unchanged as long as a sufficiently high operating voltage is supplied.

Therefore, a separate external printed circuit board with built-in Zener diodes and condensers can be removed, and the FPCB connecting the PCB and the transparent display unit 110 can also be removed, ensuring transparency and not blocking the surrounding scenery. Chronic circuit board errors and failures can be minimized. This has the advantage of reducing maintenance costs and enabling semi-permanent use.

In various embodiments, each of the one or more light emitting modules 112 may be implemented in at least one of a single module form including one LED pixel and a combined module form including a plurality of LED pixels. You can.

A single module form may mean that one light emitting module consists of one LED pixel. That is, as shown in FIG. 15, this may mean that one LED pixel forms one light emitting module itself. When one or more light emitting modules are provided in the form of a single module, transparent electrodes 113 may be provided to connect each pixel.

According to an embodiment, when the light emitting module is provided in the form of a single module, an individual controller may be provided for each LED pixel. As an example, an individual controller may be miniaturized and provided near each LED pixel, and each LED pixel may be connected through a transparent transparent electrode 113. Accordingly, transparency can be secured in areas excluding the area provided with LED pixels. According to the embodiment, when the light emitting module is provided in the form of a single module, there is an advantage that transparency is secured to the greatest extent. That is, in order to secure the highest transparency, it is desirable to configure the light emitting module in the form of a single module.

The combined module form may mean that one light emitting module is composed of a plurality of LED pixels. When each light-emitting module consists of a plurality of LED pixels, manufacturing efficiency of the light-emitting module can be improved. For example, when implementing a display by connecting each pixel, such as in the form of a single module, each pixel must be connected through a transparent electrode and each pixel must be placed in each area through a certain arrangement, increasing the difficulty of the process. do. On the other hand, when the light emitting module is provided in the form of a combined module, a plurality of LED pixels are integrated to form one light emitting module, so the transparent electrodes for connecting the light emitting modules are minimized, and the process for aligning the pixels is minimized. It can also become easier.

According to an embodiment, the combined module form may include at least one of a strip form and a wire mesh form. For example, in order for one or more light emitting modules to be provided in a combined module form, a separate frame may be required to form one light emitting module by integrating a plurality of pixels.

More specifically, each light emitting module may be formed in a strip shape in which a plurality of LED pixels 122a form one row. For a specific example, one light emitting module can be formed by connecting seven LED pixels in a regular strip shape. It can be configured by integrating a plurality of LED pixels. In an embodiment, when one or more light emitting modules are provided in the form of a strip, a certain gap may be formed between each strip, and a certain level of transparency may be secured through the gap between the strips and the gap between each pixel.

Additionally, one or more light emitting modules may be configured through a wire mesh type. The wire mesh type may be formed by connecting a plurality of LED pixels in a mesh form.

In various embodiments, the light emitting module 112 may be provided as a film type. That is, the light emitting module 112 may be implemented in the form of an LED film. In the case of the film type, transparency is secured, providing users with an excellent sense of openness. For example, in the case of the film type, it looks like transparent regular glass during the day and does not harm the surrounding scenery, but at night when it gets dark, it can be used as a display to display various visual information.

That is, the light emitting module of the present invention may be provided in at least one of a single module, a combined module, and a film form, depending on the arrangement shape and provision form. In a specific embodiment, the light emitting module may be provided in at least one of a single module form, a strip form, a wire mesh form, and a film form, as needed. All of the above four types can have transparency above a certain level, thereby making it possible to implement a transparent display. For example, high transparency can be secured in the following order: single module form, film form, strip form, and wire mesh form.

In various embodiments, the transparent display unit 110 may include a transparent electrode 113 connecting the light emitting module 112. The transparent electrode 113 may refer to a film in which an electrode is formed by thinly depositing PET, a plastic material, in an indium acid plasma state. This transparent electrode 113 is implemented through deposition of a metal material, but may be provided in a transparent form. In an embodiment, the transparent electrode is characterized by increasing the transparency of the glass and allowing the movement of electricity, and can be formed through various process methods such as the Electron Beam process, Ion Plating process, or Sputtering process.

Additionally, the transparent display unit 110 may include a bonding material 114 that secures the light emitting module 112. In one embodiment, the bonding material 114 may refer to resin or film filled between glass films. Electric elements can be fixed to each area in the space between the surface glass film 111 and the glass film 100-1 through the bonding material 114, and the inside can be maintained in a vacuum state.

In various embodiments, the transparent display unit 110 may further include a control board (not shown) including one or more input terminals that can be connected to external devices. In an embodiment, the control board is provided with a plurality of input terminals, and external devices can be connected through the corresponding input terminals. The transparent display unit 110 can be linked with external devices through the input terminal of the control board, and can display various visual information by controlling the lighting of LED pixels in response to linkage with the external device.

According to one embodiment, the transparent display unit 110 may be equipped to communicate with an external server through the MQTT protocol. The MQTT protocol is a protocol for M2M (Machine To Machine) or IOT (Internet Of Things), and may be a protocol that communicates with minimal power and packet volume. In an embodiment, MQTT may be configured through a Broker, Publisher, and Subscriber structure, rather than a client-server structure like HTTP, TCP, etc. communication. Publisher creates topics, Subscriber can subscribe to published topics, and Broker plays the role of relaying them. Since multiple subscribers can subscribe to a single topic, it is very useful in establishing 1:N communication, and through this, data such as IOT sensors can be easily managed. In other words, MQTT is advantageous for controlling small devices and collecting sensor information, and has the advantage of being easy to implement in the IOT area and delivering data efficiently. Since the transparent display unit 110 of the present invention is equipped to communicate with an external server through the MQTT protocol, it can display visual information through linkage through IOT. That is, the transparent display unit 110 may be implemented through linkage with various devices to provide visual recognition information related to the area where the transparent display unit 110 is located. For example, the transparent display unit 110 may display visual information based on connection through the Internet of Things, such as a temperature sensor device, a humidity sensor device, a speed sensor device, an illumination sensor device, and a wind volume sensor device. The detailed description of the above-mentioned sensor devices is only an example, and the present invention is not limited thereto.

According to one embodiment of the present invention, the power supply unit 120 may be provided through a dye-sensitized solar cell, as shown in FIG. 16.

The dye-sensitized solar cell is provided between the battery glass film 121, the battery glass film 121 and the glass film 100-1, and includes an electrode 124 on which transparent dye 123 (dyestuff) is adsorbed on the oxide, and It may include an electrolyte 122 that is provided between the battery glass film 121 and the glass film and allows the movement of electrons between oxides and reductions.

As the solar cell included in the transparent electronic banner 100 of the present invention is implemented through a dye-sensitized solar cell, as shown in FIG. 17, electrical energy is collected through sunlight during the day, and vehicle headlights are used at night. , by collecting street lamp light and LED light, electrical energy can be continuously obtained and supplied to the transparent display unit 110 even at night when there is no sun. In particular, light energy emitted from a plurality of LED pixels of the transparent display unit 110 provided in contact with one side of the fuel-sensitive solar cell can be recycled into electrical energy, thereby realizing a virtuous cycle of energy.
