Description

Smart pixels applicable to transparent LED media glass and their manufacturing method

[0001] The present invention relates to transparent LED media glass that provides visual information through a plurality of LEDs, and more specifically, to transparent LED media glass that can improve the lifespan and stability of the device even in an outdoor environment, and can naturally blend in with the surrounding environment without obstructing the surrounding scenery as transparency is secured.

[0002]

[0003] In modern society, transparent LED media glass is being used extensively, from building facades to urban billboards and entertainment facilities. Advances in this technology are redefining urban nightscapes, reinventing spatial experiences through interactive displays, and revolutionizing the way information is delivered. Transparent display technology opens up a new dimension in visual communication, offering a way to enhance the interaction between users and their environments.

[0004] In this regard, Korean Patent No. 10-2036603 discloses a method for implementing a current loop interface for an addressable LED (ALED) of a transparent display device and a transparent display device thereof.

[0005] Meanwhile, implementing media glass using addressable LEDs in conventional technology presents several limitations. Addressable LED (ALED) configurations are connected via an external printed circuit board (PCB) and an internal bus, requiring complex electrical paths through conductive coatings on glass or film.

[0006] More specifically, conventional components such as ALEDs, Zener diodes (ZDs), capacitors (Cs), and resistor regulators (Rs) must be integrated into a cluster, requiring the design and implementation of precise and complex conductive circuits during the manufacturing process. This process requires a high level of technical expertise, and the complexity of the process can negatively impact product stability and yield. Furthermore, if an LED defect occurs, the components must be removed using specialized equipment. This process can potentially damage the transparent circuit, making product maintenance significantly difficult.

[0007] Accordingly, there may be a demand in the industry for research and development of LED pixels that can maintain high quality and stability while significantly reducing costs and time that may arise during manufacturing and maintenance by minimizing the design and implementation of complex conductive circuits and innovatively developing efficient placement and attachment methods for ALEDs.

[0008]

[0009] The problem to be solved by the present invention is to provide a smart pixel and transparent LED media glass implemented through the smart pixel, which can maintain high quality and stability while significantly reducing costs and time that may occur during the manufacturing and maintenance process, in response to the aforementioned background technology.

[0010] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0011] A method for manufacturing transparent LED media glass including smart pixels according to one embodiment of the present invention for solving the above-described problem is disclosed. The method may include the steps of forming a transparent electrode pattern on one surface of a glass film, manufacturing a plurality of smart pixels capable of individual lighting control, mounting each of the plurality of smart pixels on one surface of the glass film on which the transparent electrode pattern is formed, and positioning another glass film on an upper surface of the plurality of smart pixels and fixing the plurality of smart pixels between the respective glass films to form transparent LED media glass.

[0012] In an alternative embodiment, the step of manufacturing the plurality of smart pixels may include the step of sequentially integrating a capacitor, an LED module, a register, and a zener diode onto a PCB substrate to manufacture each smart pixel.

[0013] In an alternative embodiment, each of the plurality of smart pixels may be characterized by having electronic components integrated within a single PCB substrate such that each has an independent pixel configuration.

[0014] In an alternative embodiment, the method further comprises the steps of performing a pre-test operation on the manufactured plurality of smart pixels and selecting smart pixels related to normal operation, wherein each of the plurality of smart pixels is provided in the form of an independent pixel and is capable of operating independently, thereby enabling a failure test before being mounted on the glass film.

[0015] In an alternative embodiment, each of the plurality of smart pixels may be arranged to form a predetermined distance in each of the plurality of areas corresponding to one surface of the glass film through a single mounting process, and may be characterized in that the connection between each smart pixel does not have a directionality.

[0016] In an alternative embodiment, the step of forming a transparent LED media glass by fixing elements between each glass film may include the step of providing a connection portion to the transparent electrode and the step of filling a bonding material between each glass film.

[0017] In an alternative embodiment, the method comprises the step of providing a power supply unit on another side of the glass film and the step of connecting the power supply unit and the connection unit, wherein the power supply unit includes a solar cell that converts light energy into electrical energy, and the solar cell may include at least one of an organic solar cell including an organic material, a silicon solar cell including a silicon-based material, a perovskite solar cell having a specific crystal structure, and a dye-sensitized solar cell (DSSC).

[0018] In an alternative embodiment, the transparent LED media glass is characterized in that it comprises three glass films, as the power supply unit is formed based on the glass film on which the transparent LED media glass is formed, and the step of providing the power supply unit on the other side of the glass film may be characterized in that each of the plurality of processes for forming the dye-sensitized solar cell is sequentially performed according to the progress of each of the plurality of process steps for forming the transparent LED media glass on the one side of the glass film.

[0019] In an alternative embodiment, the method further comprises the step of connecting the controller and the connection portion, wherein each of the plurality of smart pixels included in the transparent LED media glass is connected in series to each other through the transparent electrode pattern, and when a first smart pixel among the plurality of smart pixels receives a control signal from the controller, the first smart pixel processes the control signal and transmits the control signal to the next smart pixel, thereby causing each smart pixel to perform and transmit the control signal to display visual information, wherein the control signal may include smart pixel ID information and a lighting control signal.

[0020] A transparent LED media glass according to various embodiments of the present invention is disclosed. The transparent LED media glass includes a plurality of smart pixels capable of individual lighting control, a glass film on which the plurality of smart pixels are mounted, and a transparent electrode pattern formed on one surface of the glass film to connect the plurality of smart pixels, wherein each of the plurality of smart pixels is characterized in that electronic components are integrated into a single PCB substrate so that each has an independent pixel form, and the electronic components may include a capacitor, an LED module, a register, and a zener diode.

[0021] Other specific details of the present invention are included in the detailed description and drawings.

[0022]

[0023] According to various embodiments of the present invention, since a circuit board such as a driver PCB and FPCB for integrated control of a plurality of LEDs is not provided, the possibility of failure even in an outdoor environment is significantly reduced, thereby providing the effect of improving the stability of the device and minimizing maintenance costs.

[0024] Additionally, by implementing individually operable LED modules in the form of pixels, defect testing can be performed prior to mounting or attaching them to glass, thereby enabling defect removal prior to installation.

[0025] In addition, the integration process is simplified by implementing each component in the form of a single pixel without connecting to an external circuit, and in particular, the connection between each smart pixel can be simplified.

[0026] Additionally, by minimizing energy consumption through an energy recycling structure that recovers the electricity required for displaying information by LEDs using dye-sensitized solar cells on the back where the LED light is projected and then generates electricity again, it can help secure carbon emission rights for public facilities and solve climate problems through ESG management and energy conservation.

[0027] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

[0055]

[0056] According to one embodiment of the present invention, the transparent LED media glass may be characterized by having a certain level of transparency or higher, such that the rear portion of the device is identifiable by being transmitted through the background. That is, the transparent LED media glass (100) may naturally blend in with the surrounding environment without obscuring the surrounding landscape, thereby contributing to the improvement of a beautiful urban landscape. In other words, the present invention can provide an aesthetically pleasing transparent LED media glass that does not obscure the surrounding landscape. For example, it can create a mysterious yet luxurious feeling as if lights are floating in the air, enabling the creation of a cutting-edge urban image suitable for a smart city.

[0057] In a specific embodiment, the transparent LED media glass (100) of the present invention can implement a transparent display by configuring the display without having a driver PCB and FPCB circuit board for integrated control of a plurality of LEDs.

[0058] Transparent LED media glass (100) has the advantage of ensuring improved stability of the device even in outdoor environments and reducing maintenance costs because it does not include a PCB or FPCB circuit board (e.g., FPCB for integrated control) that is vulnerable to temperature changes and moisture.

[0059] Hereinafter, with reference to FIGS. 1 to 10, a method for implementing transparent LED media glass (100) without separately providing PCB and FPCB circuit boards for integrated control of multiple LEDs around the LED module in order to secure transparency and stability, and the effects resulting therefrom will be specifically described.

[0060] According to an embodiment, the transparent LED media glass (100) may include a plurality of smart pixels and may be characterized by controlling the lighting of the plurality of smart pixels to display visual information.

[0061] For a specific example, the transparent LED media glass (100) can provide visual information by expressing the current time (e.g., 3:04) in text form by lighting up at least some of the plurality of smart pixels, or can provide visual information by expressing the current weather (e.g., rain) in picture form. The specific description of the visual information described above is only an example, and it will be apparent to those skilled in the art that the transparent LED media glass of the present invention can provide a wider variety of information (e.g., emergency disaster information, forward accident information, advertisement information, weather information, local public information, etc.) through various forms of visual expression. For example, the transparent LED media glass (100) can provide a visual expression with dynamics, such as text moving in one direction or an object being given movement, through gradual lighting up between the plurality of smart pixels. As another example, the transparent LED media glass (100) can express more vivid objects or characters, etc., by lighting up each smart pixel with various colors.

[0062] The transparent LED media glass (100) of the present invention, due to its transparency, can blend seamlessly into the surrounding landscape without obscuring it. For example, it can create a mysterious yet luxurious feel, as if lights are floating in the air, enabling the creation of a cutting-edge urban image suitable for a smart city. Furthermore, for example, during the day when no visual information is displayed, it can appear like ordinary transparent glass, thus not obscuring the surrounding landscape.

[0063] According to one embodiment, in the case of a display utilizing a general LED, the light is controlled by directly changing the voltage of each of the plurality of LED elements. For example, the light of the LED elements can be controlled through voltages related to RGB. In this case, all LEDs connected to the same line emit the same color. Accordingly, when general LEDs are utilized, various effects such as a rainbow effect (e.g., an effect in which LEDs display different colors simultaneously) or a wave effect (e.g., a sequential motion effect in which LEDs sequentially turn on or off) cannot be provided, and accordingly, there is a limitation in that the diversity of visual information that can be expressed through the display is limited.

[0064] Additionally, a separate LED driver may be required to control multiple LEDs, and such a driver is implemented in the form of a PCB. Since such a PCB must be installed in close proximity to the display (e.g., on the side or back), it has limitations in that it cannot provide complete transparency to the display and cannot reduce the possibility of failure.

[0065] For example, referring to FIGS. 1 and 2, in order to secure a certain level of transparency in the display unit, an LED driver (e.g., a driver composed of a PCB or FPCB substrate) for controlling LEDs may be compressed and mounted on a side frame portion to implement transparent LED media glass (or LED display board, electronic banner, etc.). That is, in order to secure transparency, the driver PCB may be placed in the side frame area, and each of a plurality of LEDs mounted on the glass film may be connected to the driver PCB via an electrode to implement transparent LED media glass. In the case of transparent LED media glass as shown in FIGS. 1 and 2, each LED and the driver PCB may be connected in parallel in an LED individual control manner, and the driver PCB may be placed in the side frame area to be configured.

[0066] However, conventional transparent LED media glass can suffer from device failure due to contamination or corrosion of the driver PCB board caused by temperature changes or moisture generated in outdoor environments, resulting in significant maintenance costs. Because the driver PCB cannot be completely sealed in this side area, it is highly vulnerable to moisture and temperature changes in outdoor environments.

[0067] In addition, conventional transparent LED media glasses with this configuration have a limitation in that they cannot have complete transparency because the driver PCB in the form of an opaque substrate is placed in the side frame area.

[0068] Meanwhile, transparent LED media glass utilizing addressable LEDs (ALEDs, Addressable LEDs, or LED pixels) has been developed and is being offered to ensure complete transparency (e.g., transparency up to the frame area). A more detailed description of transparent LED media glass implemented using ALEDs is discussed in detail in Republic of Korea Patent Publication No. 10-2036603.

[0069] In the case of transparent LED media glass utilizing addressable LEDs (or transparent LED media glass according to another embodiment), it may be characterized by not having a driver PCB for integrated control of multiple LEDs, but individually providing electronic components for controlling each LED corresponding to each LED pixel module (i.e., ALED module).

[0070] In the case of transparent LED media glass utilizing conventional addressable LEDs (hereinafter referred to as "ALEDs"), as illustrated in Fig. 3 (a), each ALED module may be configured with electronic components for individual control of each LED. Through this configuration, a separate driver PCB for integrated control of the lighting of multiple LEDs may not be separately provided, so that transparency can be provided even in the side frame area. In addition, since the circuit board for controlling the lighting of each ALED is sealed and arranged within the glass film, there is an advantage in that the device's stability is enhanced even in outdoor environments, thereby reducing maintenance costs. In other words, in the case of transparent LED media glass utilizing ALEDs, components such as a resistor and a capacitor constitute a single ALED, and each ALED is arranged in series on one side of the glass film, enabling control through single-wire design technology. This enables the elimination of side components, simplifying the structure and implementing a bezel-less product, and has the advantage of being able to be installed in outdoor environments such as aquatic facilities due to improved waterproofing performance.

[0071] In the embodiment, each ALED must use a Zener diode (ZD) as a voltage regulator because the voltage must remain constant to avoid interference with data (e.g., control signal) transmission. Additionally, a separate voltage regulator (e.g., Zener diode) and a series capacitor (C) in the series line to overcome ground potential must be provided. A transparent LED media glass utilizing conventional ALEDs can provide a current loop interface that allows uninterrupted serial data communication between LED pixels and allows a bundle of LED pixels to have flexible energy consumption.

[0072] In a specific embodiment, as illustrated in (b) of FIG. 3, a plurality of ALEDs may be connected in series to form a loop. The ALEDs are independently formed through connections between electronic components so that they can be individually controlled, and each ALED may be electrically connected via a transparent electrode. That is, a plurality of ALEDs are mounted on one surface of a glass film, each ALED is connected via a transparent electrode, and the transparent electrodes connected to the plurality of ALEDs are connected to a power supply unit and a controller for supplying power.

[0073] Meanwhile, transparent LED media glass utilizing ALEDs has the disadvantage of a complex process for forming each ALED module on the glass film, and there is a problem in that defects cannot be detected before each ALED is formed on the glass film. For example, in the case of transparent LED media glass utilizing ALEDs, operation is possible only after each ALED is installed on the glass film, so preliminary testing for defects cannot be performed before integration onto the glass film. As such, the inability to perform preliminary defect testing poses a risk of defective inspection. For example, once components are mounted on the glass film, they are difficult to remove, which can greatly reduce efficiency. In other words, while there are advantages to not using a driver PCB, there may be a risk of defective inspection in terms of the product.

[0074] The present invention aims to provide a transparent LED media glass (100) that improves upon the problems that existed in the above-mentioned conventional transparent LED media glass (e.g., transparent LED media glass implemented by arranging a driver PCB in a side area and transparent LED media glass utilizing ALED).

[0075] Since the transparent LED media glass (100) of the present invention does not require arranging a driver PCB connected in parallel with a plurality of LEDs in the side frame area, the side area can also be implemented transparently, and since vulnerability to moisture is prevented, durability and stability can be improved.

[0076] The present invention can manufacture smart pixels and implement transparent LED media glass (100) by utilizing the same. In an embodiment, the smart pixels of the present invention can be applied by integrating components necessary for LEDs (e.g., resistors, capacitors, diodes, etc.) into a single pixel. The present invention can implement each smart pixel by integrating electronic components into a single PCB substrate so that each smart pixel has an independent pixel form. Such smart pixels can enable preemptive defect detection, provide convenience in circuit implementation, and improve display resolution.

[0077] More specifically, referring to FIGS. 3 and 4, in the case of a conventional transparent LED media glass utilizing ALEDs, a process for forming each ALED at a certain interval on one side of the glass film must be performed. For example, an LED, a capacitor, a resistor, and a Zener diode (z-diode) may be sequentially integrated on one area of ​​one side of the glass film to form one ALED. In this way, one ALED is formed through four mounting processes corresponding to four components, and the process for creating multiple ALEDs on each area is repeated multiple times.

[0078] In contrast to conventional technologies that require four mounting processes to produce a single ALED module, the smart pixel of the present invention requires only a single mounting process to mount the smart pixel itself on a glass film, as the elements within the pixel are integrated and formed into a single pixel. This has the advantage of simplifying the integration process.

[0079] Additionally, in the case of a conventional ALED, a Zener diode and a capacitor are positioned on one side (e.g., the left side) of the LED module, a resistor is positioned on the other side (e.g., the lower side), and the LED module and each component are connected to an external circuit to implement the ALED. In other words, each component is configured to be externally connected through an external circuit.

[0080] On the other hand, in the case of the smart pixel of the present invention, since the elements are integrated and formed on a single LED pixel (i.e., a PCB substrate), external circuits for connection with the elements are not necessarily required, making implementation easy. In other words, external circuits for connection with each element can be omitted.

[0081] In addition, since each element of a conventional ALED is arranged at a single position of an LED pixel, each ALED must be provided with a certain directionality when connected in series. For example, as illustrated in (b) of FIG. 3, a design is essential in which the transparent electrode starts from a single direction due to the arrangement direction of the electronic elements included in each ALED. In the case of the smart pixel of the present invention, since all components are manufactured as an integrated unit in the form of a single pixel, as illustrated in FIG. 6, there is an advantage in that the electrodes can be connected on all four sides, eliminating the need for a directionality of the circuit arrangement, and thus the arrangement spacing between each smart pixel can be minimized. For example, in the case of a conventional transparent LED media glass, the minimum arrangement spacing between each ALED may be 25 mm, but in the case of the transparent LED media glass (100) of the present invention, the minimum arrangement spacing between each smart pixel may be 18 mm. This reduction in the minimum arrangement spacing can enable implementation with high resolution.

[0082] In addition, in the case of conventional transparent LED media glass, since operation is possible after the ALED is installed on one side of the glass film, there is a problem in that inspection for defects cannot be performed before the ALED is implemented on the glass film (i.e., each element is sequentially mounted and formed to implement the ALED). For example, the ALED is installed after four mounting processes are performed, and operation is possible after installation, so defects can be identified at a later time. If a defect is identified after the ALED is installed, the installed ALED must be removed again, but it is difficult to remove the elements once mounted without a trace, and since the elements may be damaged during the removal process, it is very inefficient and there is a risk of defect removal.

[0083] In the case of the smart pixel of the present invention, since the related elements are implemented in an integrated pixel form, there is an advantage in that a preliminary defect test can be performed before mounting on a glass film.

[0084]

[0085] Figure 5 illustrates a flowchart exemplifying a method for manufacturing transparent LED media glass according to the present invention. The steps illustrated in Figure 5 may be rearranged as needed, and at least one step may be omitted or added. The steps illustrated in Figure 5 are merely one embodiment of the present invention, and the scope of the present invention is not limited thereto.

[0086] Referring to FIG. 5, the method for manufacturing transparent LED media glass of the present invention may include a step (S100) of forming a transparent electrode pattern on one surface of a glass film. The transparent electrode pattern may refer to a pattern formed with a transparent electrode (120) for electrically connecting each of a plurality of smart pixels (130). In an embodiment, the transparent electrode pattern may be formed through a pattern as illustrated in (b) of FIG. 6, as a pattern for connecting a plurality of smart pixels (130) in series.

[0087] According to an embodiment, each smart pixel can be connected through a transparent electrode (120). Accordingly, transparency can be secured in an area excluding an area where a smart pixel (130) is provided. In one embodiment, a transparent electrode pattern is formed as a process for forming a transparent electrode pattern on one surface of a glass film (110) is performed, and a plurality of smart pixels (130) are respectively arranged in response to the transparent electrode pattern.

[0088] The transparent electrode (120) may refer to a film formed by thinly depositing PET, a plastic material, in an indium acid plasma state. This transparent electrode (120) is implemented through the 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 glass and allowing the movement of electricity, and may be formed through various processing methods such as an electron beam process, an ion plating process, or a sputtering process.

[0089] According to one embodiment of the present invention, the method for manufacturing transparent LED media glass of the present invention may include a step (S200) of manufacturing a plurality of smart pixels (130) capable of individual lighting control.

[0090] Referring to FIG. 4, each of the plurality of smart pixels (130) of the present invention may be characterized in that electronic components are integrated within a single PCB substrate so that each has an independent pixel form. Here, the electronic components may include a capacitor, an LED module, a register, and a zener diode (z-diode). In an embodiment, each smart pixel (130) may be equipped with a zener diode (ZD) for voltage regulation because the voltage must not change so as not to interfere with data (e.g., control signal) transmission. In addition, a separate voltage regulator (e.g., zener diode) and a series of capacitors (C) in a series line to overcome ground potential may be equipped.

[0091] In an embodiment, the transparent LED media glass (100) can be implemented with a current loop interface that allows uninterrupted serial data communication between smart pixels and allows the LED pixel bundles to have flexible energy consumption. Utilizing such a current loop interface allows for the complete elimination of the Zener diode and voltage regulator, as long as a sufficiently high operating voltage is supplied, data transmission continues to operate. Therefore, a separate external printed circuit board with a built-in Zener diode and capacitor can be eliminated, and the FPCB connecting the PCB and the transparent LED media glass can also be eliminated. This ensures transparency, thereby preventing obstruction of the surrounding landscape and minimizing chronic circuit board errors and failures. This has the advantage of reducing maintenance costs and enabling semi-permanent use.

[0092] In an embodiment, the step of manufacturing a plurality of smart pixels may include a step of manufacturing each smart pixel by sequentially integrating a capacitor, an LED module, a resistor, and a Zener diode onto a PCB substrate. For example, each smart pixel may be provided by sequentially connecting a capacitor, a resistor, a Zener diode, and a capacitor.

[0093] According to one embodiment, the present invention may be characterized by performing a test for defect detection prior to mounting the smart pixel on the glass film.

[0094] In a specific embodiment, the method for manufacturing transparent LED media glass of the present invention may further include a step of performing a pre-test operation on a plurality of manufactured smart pixels and a step of selecting smart pixels related to normal operation. The present invention can perform a pre-test for defect detection and select only smart pixels determined to be operating normally and mount them on a glass film.

[0095] Since each of the plurality of smart pixels (130) of the present invention is provided in the form of an independent pixel and can operate independently, a defect test can be performed before mounting on the glass film (110).

[0096] In the case of conventional transparent LED media glass, since operation is possible only after the ALED is installed on one side of the glass film, there is a problem in that inspection for defects cannot be performed before the ALED is implemented on the glass film (i.e., each element is sequentially mounted and formed to implement the ALED). For example, the ALED is installed after four mounting processes are performed, and since operation is possible after installation, defects can be identified at a later time. If a defect is identified after the ALED is installed, the installed ALED must be removed again. However, it is difficult to remove the elements once mounted without a trace, and since the elements may be damaged during the removal process, it is very inefficient and there is a risk of defect removal.

[0097] In the case of the smart pixel of the present invention, since the related elements are implemented in the form of a single integrated pixel, there is an advantage in that a preliminary defect test can be performed before mounting on a glass film.

[0098] According to one embodiment of the present invention, the method for manufacturing a transparent LED media glass of the present invention may include a step (S300) of mounting each of a plurality of smart pixels on one surface of a glass film on which a transparent electrode pattern is formed.

[0099] According to an embodiment, each of the plurality of smart pixels (130) may be arranged to form a predetermined distance in each of the plurality of areas corresponding to one side of the glass film through a single mounting process, and may be characterized in that the connection between each smart pixel does not have a directionality.

[0100] For example, in the case of a conventional ALED, a Zener diode and a capacitor are positioned on one side (e.g., the left side) of the LED module, a resistor is positioned on the other side (e.g., the lower side), and the LED module and each component are connected to an external circuit to implement the ALED. In other words, each component can be externally connected through an external circuit.

[0101] On the other hand, in the case of the smart pixel (130) of the present invention, as illustrated in FIG. 7, since the elements are integrated and formed in one LED pixel (i.e., a PCB substrate), an external circuit for connection with the elements is not necessarily required, so implementation is easy.

[0102] In addition, since each element of a conventional ALED is arranged at a single position of an LED pixel, each ALED must be provided with a certain directionality when connected in series. For example, as illustrated in (b) of FIG. 3, a design is essential in which the transparent electrode starts from a single direction due to the arrangement direction of the electronic elements included in each ALED. In the case of the smart pixel of the present invention, since all components are manufactured as an integrated unit in the form of a single pixel, as illustrated in FIG. 6, there is an advantage in that the electrodes can be connected on all four sides, eliminating the need for a directionality of the circuit arrangement, and thus the arrangement spacing between each smart pixel can be minimized. For example, in the case of a conventional transparent LED media glass, the minimum arrangement spacing between each ALED may be 25 mm, but in the case of the transparent LED media glass (100) of the present invention, the minimum arrangement spacing between each smart pixel may be 18 mm. This reduction in the minimum arrangement spacing can enable implementation with high resolution.

[0103] According to one embodiment of the present invention, the method for manufacturing transparent LED media glass of the present invention may include a step (S400) of positioning another glass film on the upper surface of a plurality of smart pixels and fixing a plurality of smart pixels between each glass film to form transparent LED media glass (100).

[0104] Fixing a plurality of smart pixels between a glass film (110) and another glass film (111) may be performed by utilizing a bonding agent (140). In one embodiment, the bonding agent (140) may refer to a resin or film filled between the glass films. If the electrical elements can be fixed to each region on the inside of both glass films through the bonding agent (140), the inside of the glass films can also be maintained in a vacuum state. Meanwhile, since the PCB substrate for individual lighting control of each smart pixel is maintained in a vibrating state between the glass films, improved stability can be ensured even against various factors such as moisture or temperature changes.

[0105] In a specific embodiment, the step of forming a transparent LED media glass (100) by fixing elements between each glass film may include the step of providing a connecting portion (150) to a transparent electrode (120) and the step of filling a bonding material (140) between each glass film. The connecting portion (150) may mean a connecting terminal for connection with a controller and a power supply portion (200) (e.g., power). The connecting portion (150) is positioned in an area (e.g., an end) between the glass films, as illustrated in FIG. 8, and may be connected to the controller via a cable.

[0106] According to one embodiment of the present invention, the method for manufacturing transparent LED media glass may further include a step of connecting the controller and the connecting portion (150).

[0107] Each of a plurality of smart pixels included in a transparent LED media glass (100) is connected in series to each other through a transparent electrode pattern, and when a first smart pixel among the plurality of smart pixels receives a control signal from a controller, the first smart pixel processes the control signal and transmits the control signal to the next smart pixel, thereby displaying visual information by causing each smart pixel to perform and transmit the control signal. Here, the first smart pixel may mean a smart pixel among the plurality of smart pixels that is first connected in series to a connection unit (150).

[0108] More specifically, referring to FIG. 9, a control signal may be transmitted from the controller to the transparent LED media glass. In this case, the control signal may include smart pixel ID information and a lighting control signal. The smart pixel ID information is ID information regarding which smart pixel among a plurality of smart pixels it is, and the lighting control signal may include information regarding a lighting control method. For example, the control signal may include smart pixel ID information related to a third smart pixel, a seventh smart pixel, and a ninth smart pixel, and may include a lighting control signal instructing the pixel to blink red repeatedly for 3 seconds from a reference time. The specific description of the above-described control signals is merely an example, and the present invention is not limited thereto.

[0109] The first smart pixel initially connected to the connection unit (150) can receive a control signal. The first smart pixel can process the received control signal. The first smart pixel can check smart pixel ID information to determine whether to process the lighting control signal. For example, only the smart pixel corresponding to the smart pixel ID information can process the lighting control signal. After processing the control signal, the first smart pixel can transmit the control signal to the second smart pixel. The second smart pixel may refer to a smart pixel connected in series to the first smart pixel. The second smart pixel can receive the control signal from the first smart pixel and process the received control signal. Thereafter, the second smart pixel transmits the control signal to the third smart pixel. In this way, the control signal is sequentially transmitted to the smart pixels connected in series, and the corresponding smart pixel performs a lighting control operation corresponding to the control signal, thereby displaying visual information to the outside.

[0110] According to one embodiment, the transparent LED media glass (100) may be characterized by being equipped to communicate with an external server via 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 or TCP. The Publisher generates a topic, the Subscriber can subscribe to the published topic, and the Broker acts as a relay between them. Since multiple Subscribers can subscribe to a single topic, it is very useful for establishing 1:N communication, and this allows for easy management of data such as IOT sensors. 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 field and efficiently transmitting data. The transparent LED media glass (100) of the present invention is equipped to communicate with an external server via the MQTT protocol, and thus can display visual information through connection via the Internet of Things (IoT). That is, the transparent LED media glass (100) can be implemented through connection with various devices to provide visual recognition information related to the space in which the transparent LED media glass (100) is located. For example, the transparent LED media glass (100) can display visual information based on connection via the Internet of Things (IoT), such as a temperature sensor device, a humidity sensor device, a speed sensor device, an illuminance sensor device, and an air volume sensor device. The specific description of the above-described sensor devices is merely an example, and the present invention is not limited thereto.

[0111] According to one embodiment, the method for manufacturing transparent LED media glass of the present invention may include a step of providing a power supply unit (200) on the other side of a glass film (e.g., a glass film on which transparent LED media glass is formed) and a step of connecting the power supply unit (200) to a connection unit. The power supply unit (200) may include a solar cell that converts light energy into electrical energy.

[0112] According to one embodiment of the present invention, the solar cell may include at least one of an organic solar cell including an organic material, a silicon solar cell including a silicon-based material, a perovskite solar cell having a specific crystal structure, and a dye-sensitized solar cell (DSSC).

[0113] According to an embodiment, the solar cell may include at least one of an organic solar cell including an organic material and a silicon solar cell including a silicon-based material.

[0114] Organic solar cells can be solar cells constructed using organic materials. Organic solar cells can be manufactured on a large area, offering convenience in the manufacturing process and enabling mass production. Furthermore, because they are constructed using organic materials, they can be made flexible and have the advantage of low manufacturing costs.

[0115] In some embodiments, a silicon-based solar cell is implemented using a semiconductor material such as silicon, and may refer to a device that converts light energy into electrical energy using silicon wafers. While silicon-based solar cells may have somewhat lower efficiency, they have the advantage of readily available materials and low manufacturing costs.

[0116] In addition, according to an embodiment, the solar cell may include a perovskite solar cell having a specific crystal structure. Perovskite is a semiconductor material with a hexagonal structure and may refer to perovskite. Perovskite solar cells can be implemented through a simple manufacturing process and have the advantage of being able to be deposited on various substrates. For example, in the case of silicon-based solar cells, processing is performed at temperatures of over 1400 degrees Celsius using expensive equipment, but perovskite can be processed in a liquid solution at a relatively low temperature of around 100 degrees Celsius using inexpensive equipment. In addition, perovskite can be deposited on various substrates, including flexible plastic. This has the advantage of being able to be used in a variety of ways, unlike thick and rigid silicon wafers.

[0117] Additionally, according to an embodiment, the solar cell may include a dye-sensitized solar cell (DSSC). For example, the dye-sensitized solar cell may be a solar cell that operates on a principle similar to the principle of photosynthesis in plants.

[0118] Specifically, dye-sensitized solar cells operate on the principle that special dye molecules chemically adsorbed on the surface of a metal oxide absorb light, generate electrons, and collect the generated electrons at an electrode to produce electrical energy. In an embodiment, dye-sensitized solar cells can be made transparent using a transparent dye, or can be made in various colors using dyes of various colors, thereby providing high versatility.

[0119] These dye-sensitized solar cells have a relatively simple structure, so their manufacturing cost is only 20-50% of that of silicon-based solar cells. In addition, dye-sensitized solar cells have the advantage of having almost no decrease in efficiency depending on the incident angle of light, and higher power generation during the day and night than other solar cells. In other words, since dye-sensitized solar cells have almost no decrease in efficiency depending on the incident angle, they do not need to be installed in the direction of sunlight incidence, so they have high autonomy and flexibility in their installation location, and have the advantage of generating electrical energy based on various light energies (e.g., car headlights, light emitted from LEDs, or streetlights) even when there is no sun.

[0120] When utilizing a dye-sensitized solar cell, transparency can be ensured, so it is most preferable that the transparent LED media glass (100) of the present invention be connected to a dye-sensitized solar cell to ensure transparency.

[0121] Since the solar cell connected to the transparent LED media glass (100) of the present invention is implemented using a dye-sensitized solar cell, electric energy is collected through sunlight during the day, and electric energy is collected from vehicle headlights, streetlights, and LED lights at night, so that electric energy can be continuously obtained and supplied to the transparent LED media glass (100) even at night when there is no sun. In particular, light energy emitted from a plurality of LED pixels of the transparent LED media glass (100) provided in contact with one surface of the dye-sensitized solar cell can be recycled into electric energy, thereby implementing a virtuous cycle of energy.

[0122] According to one embodiment of the present invention, the power supply unit (200) may be provided with a shape corresponding to a transparent LED media glass.

[0123] Meanwhile, the transparent LED media glass (100) of the present invention can be implemented by bonding (e.g., bonding glass films) the transparent LED media glass (100) and the power supply unit (200) back to back. That is, as illustrated in FIG. 10 (a), the transparent LED media glass (100) can be implemented through a bonding process between the power supply unit (200) that supplies power and the transparent LED media glass (100) that displays visual information. For a specific example, the transparent LED media glass (100) and the power supply unit (200) can be created through their respective manufacturing processes, and then the transparent LED media glass (100) can be created through a bonding process of the respective glass films. That is, the transparent LED media glass (100) and the power supply unit (200) can be integrated through a bonding process between the glass films.

[0124] According to an embodiment, a dye-sensitized solar cell may include an electrode (230) with a dye adsorbed thereon and an electrolyte (220) provided between a cell glass film (210), as illustrated in FIG. 10.

[0125] In a specific embodiment, a dye-sensitized solar cell may include a battery glass film (210), an electrode (230) provided between the battery glass film (210) and having a dye having transparency adsorbed on an oxide, and an electrolyte (220) provided between the battery glass film (210) and the glass film and allowing movement of electrons between the oxide and the reduced product.

[0126] That is, the transparent LED media glass (100) of the present invention can be formed by performing a bonding process between one side of the glass film (110) of the transparent LED media glass (100) and one side of the battery glass film (210) of the power supply unit (200), as illustrated in (a) of FIG. 10. In this case, the transparent LED media glass (100) and the power supply unit (200) are produced through their respective manufacturing processes, and then the transparent LED media glass (100) can be produced through a bonding process of the respective glass films, so the manufacturing process is easy and simple.

[0127] According to another embodiment of the present invention, the transparent LED media glass (100) may be characterized in that it is configured to include three glass films, as the power supply unit (200) is formed based on the glass film (110) on which the transparent LED media glass (100) is formed. That is, as illustrated in (b) of 10, the transparent LED media glass (100) may be configured to include three glass films, as the power supply unit (200) is formed based on the glass film forming one side of the transparent LED media glass (100).

[0128] In a specific embodiment, the step of providing a power supply unit on the other side of the glass film may be characterized by sequentially performing each of a plurality of processes for forming a dye-sensitized solar cell according to the progress of each of a plurality of process steps in which a transparent LED media glass (100) is formed on one side of the glass film.

[0129] For example, when transparent LED media glass (100) and power supply unit (200) are individually produced through each manufacturing process and then the transparent LED media glass (100) is manufactured through a glass film bonding process, it is configured to include two glass films each, and as a result, a total of four glass films are included.

[0130] Thus, when transparent LED media glass is implemented using four glass layers, the multiple glass layers increase manufacturing costs and increase the thickness and weight of the product. This can reduce the stability of transparent LED media glass, which is often installed in high locations (e.g., approximately 2 meters or higher).

[0131] In order to solve the problems such as increased process cost and decreased stability as described above, the present invention can implement a transparent LED media glass (100) by performing a process of forming a transparent LED media glass (100) and a power supply unit (200) on each of two sides based on a single glass film.

[0132] As shown in (b) of Fig. 10, when a transparent LED media glass (100) and a power supply unit (200) are formed on each side by sharing a single glass film, the number of glass films utilized overall can be reduced compared to a manufacturing method in which the transparent LED media glass (100) and the power supply unit (200) are manufactured separately and then bonded together, thereby lowering the production cost.

[0133] According to a specific embodiment, the transparent LED media glass (100) may be characterized by including a total of three glass films as the transparent LED media glass (100) is formed based on the glass film constituting one side of the power supply unit (200). In general, the transparent LED media glass (100) (or electronic banner) is installed in a high place so that a large number of users can see it. For example, the transparent LED media glass (100) may be installed on a support such as a streetlight or a utility pole. In the case of the transparent LED media glass (100) of the present invention, since both the power supply unit (200) and the transparent LED media glass (100) are transparent and are provided to include only three glass films, it can be implemented with a relatively small weight and a thin thickness, so that it can blend in more naturally with the surrounding landscape, and can be more stably coupled to the support due to its light weight.

[0134] In this way, since the thickness and weight of the final manufactured transparent LED media glass (100) are reduced by including a smaller glass film, the stability of the transparent LED media glass installed at high locations can be improved. In other words, the commercial viability and stability of the product can be improved due to increased process efficiency, weight reduction, and increased durability.

[0135] Meanwhile, when a process of manufacturing a power supply unit (200) and a transparent LED media glass (100) on each of both sides based on a single glass film is performed, the stability of the manufactured transparent LED media glass (100) may be reduced depending on the influence between each process.

[0136] Specifically, in the case of the solar cell corresponding to the power supply unit (200) in the present invention, a high temperature is required during the manufacturing process. For example, in the case of a dye-sensitized solar cell, a high temperature of about 500°C may be required during the sintering process to form the photoelectrode, and this high temperature of 500°C may affect the transparent LED media glass (100) provided on the back side of the dye-sensitized solar cell. For example, in the case of the transparent LED media glass (100), the smart pixel can be fixed through a bonding material (e.g., resin or film). However, due to the high temperature of 500°C required for sintering the photoelectrode on the opposite side, the bonding material composed of resin may melt, causing the smart pixel to not be fixed and to fall off, or the inside of the transparent LED media glass (100) may not be maintained in a vacuum state. Accordingly, the process for the display unit that integrates the smart pixel and the process for forming the solar cell cannot be performed simultaneously.

[0137] Therefore, in the process of creating a transparent LED media glass (100) and a power supply unit (200) based on a single glass film, it is very important to specifically plan the process order and process method so as not to be affected by the two processes.

[0138] Hereinafter, a detailed description will be given of a specific process method for forming a dye-sensitized solar cell sequentially according to the progress of each of the plurality of process steps in which a transparent LED media glass (100) is formed on one side of the glass film, so as not to be influenced by each process during the process of manufacturing a display unit and a power supply unit on each side of a single glass film.

[0139] In one embodiment, a dye-sensitized solar cell may be provided as a power supply unit (200) in contact with (or sharing a single glass film with) a transparent LED media glass (100).

[0140] In a specific embodiment, a method for forming a transparent LED media glass (100) and a dye-sensitized solar cell, respectively, corresponding to one side (e.g., a first side) and a second side (e.g., the other side) of a glass film may include a step of providing a transparent electrode pattern and a DSSC module on each of the first side and the second side, a step of providing a protective film on a surface corresponding to the first side, a step of performing a TiO2 coating corresponding to the second side, a step of sintering TiO2 to form a photoelectrode, a step of attaching a protective layer to a surface corresponding to the first side after the photoelectrode is formed, a step of adsorbing a dye on the surface of the photoelectrode, a step of bonding a counter electrode corresponding to the photoelectrode, a step of mounting one or more light-emitting modules corresponding to the first side after the bonding of the counter electrode is completed, and a step of performing sealing by injecting an electrolyte layer corresponding to the second side after the mounting of one or more light-emitting modules is completed.

[0141] In one embodiment, the method may include a step of providing a light-emitting module and a DSSC module on each of the first and second surfaces of the glass film. For example, the glass film may be FTO glass, and an LED module for implementing a transparent LED media glass (100) and a DSSC module for implementing a dye-sensitized solar cell are implemented on each of both surfaces of the glass film. The LED module and the DSSC module may refer to electrodes for electrically connecting electronic components of the transparent LED media glass and the dye-sensitized solar cell, respectively.

[0142] In one embodiment, the method may include a step of providing a protective film on a surface corresponding to the first side. In various embodiments, the protective film is provided to protect the surface of the transparent LED media glass (100) and may be characterized in that it is removed before forming the photoelectrode. The protective film may be for preventing damage to the LED electrode. When designing an FTO-based double-sided electrode, a protective film for preventing damage to the LED electrode must be provided. Since such a protective film may deteriorate or be absorbed by high temperatures during the photoelectrode firing process of a dye-sensitized solar cell, it must be removed before the photoelectrode firing.

[0143] In one embodiment, the method may include a step of performing a TiO2 coating corresponding to the second surface. According to an embodiment, TiO2 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 TiO2 surface of the photoelectrode receive light and generate electrons. In an embodiment, TiO2 can be coated using various processing methods such as doctor blade, spin coating, and screen printing.

[0144] In one embodiment, the method may include a step of sintering TiO2 to form a photoelectrode. In a specific embodiment, TiO2 paste is coated on the second surface of the FTO glass using a doctor blade after tape casting, and then sintered at a temperature of 500°C for a predetermined period of time (e.g., 60 minutes).

[0145] In one embodiment, the method may include, after the photoelectrode is formed, attaching a protective layer to a surface corresponding to the first surface. In one embodiment, the protective layer is provided to protect the LED electrode during the firing or handling of the photoelectrode, and may be formed of a material that does not deform at high temperatures. The protective layer is attached to the first surface and handled to protect the LED electrode after the sintering process of the photoelectrode.

[0146] In one embodiment, the method may include a step of adsorbing a dye onto the surface of the photoelectrode. For example, after the photoelectrode is formed, cooling may be performed within an electric furnace to a predetermined temperature (e.g., 80°C), and the cooled substrate may be immersed in the dye for a predetermined period of time (e.g., 24 hours), thereby adsorbing the dye.

[0147] In one embodiment, the method may include a step of bonding a counter electrode corresponding to the photoelectrode. In the embodiment, a Pt paste may be coated on the second surface of the FTO glass 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.

[0148] In one embodiment, the method may include a step of mounting one or more light-emitting modules corresponding to the first surface after the bonding of the counter electrode is completed. That is, after the fabrication of the positive electrode (i.e., the photoelectrode and the counter electrode) of the dye-sensitized solar cell is completed, a plurality of smart pixels are mounted on the circuit of the transparent electrode pattern.

[0149] In one embodiment, the method may include a step of performing sealing by injecting an electrolyte layer corresponding to the second surface after the mounting of a plurality of smart pixels (130) is completed. That is, after the production of the transparent LED media glass (100) is completed, the electrolyte is injected and then sealing is performed, thereby realizing a dye-sensitized solar cell.

[0150] The present invention can prevent the power supply unit (200) including the dye-sensitized solar cell and the transparent LED media glass (100) from being affected by performance degradation during each production process through the process sequence or process steps described above. In other words, the transparent LED media glass (100) of the present invention can be manufactured by providing the dye-sensitized solar cell and the transparent LED media glass (100) with their backs facing each other so as not to be affected during each production process.
