[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] It should be noted that the terms "upper side", "lower side", "inner side", "outer side", "upper part", "lower part", "one side", "one end", "one side", "outer edge", "outer edge", "middle section", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "assembly," "equipped with," "set up," "located in," "fixed," "connected," "linked," "attached," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0019] Please refer to Figure 1 The LCD screen 2 is cylindrical, and its actual size should be determined based on the size of the load-bearing column 19 in the indoor hall. Generally, the larger the load-bearing column 19 is, the larger the LCD screen 2 will be.

[0020] The LCD screen 2 is an LED display screen, and its static (power off) color is black. The function of the LCD screen 2 is to convert electrical signals into image signals, that is, to convert digital signals into image displays.

[0021] The LCD screen 2 is equipped with two matching pressure feet 3. The pressure feet 3 have a rolled T-shaped structure and are preferably made of alloy material. The pressure feet 3 mainly serve to connect or fix the LCD screen 2 and the frame 1 by fitting into a slot on one side of the frame 1 to enhance the stability between the LCD screen 2 and the frame 1.

[0022] The pressure foot 3 consists of a long strip support and an insert. The insert is arranged in a longitudinal ring in the middle of one side of the support. The outer perimeter of the support is consistent with the outer perimeter of the LCD screen 2, and the width of the support is equal to the thickness of the LCD screen 2.

[0023] Two pressure feet 3 are arranged in a ring around the upper and lower sides of the LCD screen 2 as required. In fact, the two support plates are firmly fixed to the upper and lower sides of the LCD screen 2 with a special adhesive (PUR hot melt adhesive).

[0024] The LCD screen 2 is equipped with two annular bezels 1 of matching dimensions (circumference and width). The bezels 1 are preferably made of alloy material and have a black anti-static coating on the outside to enhance aesthetics and maintain harmony with the static color of the LCD screen 2. The function of the bezels 1 is to fix and protect the LCD screen 2, ensuring its stable installation.

[0025] A slot, large enough to accommodate an insert piece, is made along one end of the upper or lower side of each of the two frame 1s, extending to the other end. Both ends of the slot penetrate the outer side of the corresponding frame 1. The slot is the main connecting part on the frame 1, and by fitting and engaging with the insert piece, a firm connection is formed between the frame 1 and the liquid crystal display screen 2.

[0026] The liquid crystal display screen 2 is securely mounted between the two circular frame frames 1. Since the width of the support plate is consistent with the thickness of the liquid crystal display screen 2, the outer curvature of the frame frame 1 and the outer curvature of the liquid crystal display screen 2 are integrated and extended or perfectly matched.

[0027] Installation process of frame 1: After fitting the upper part of the LCD screen 2 into the slot on the lower side of the upper frame 1, fix it with PUR hot melt adhesive. After fitting the lower part of the LCD screen 2 into the slot on the upper side of the lower frame 1, fix it with PUR hot melt adhesive, so that the LCD screen 2 and the frame 1 are integrated and connected.

[0028] Please refer to Figure 2 The inner cavity enclosed by the liquid crystal display screen 2 is provided with a support 4. The support 4 is a dumbbell-shaped hollow structure, preferably made of insulating PC plastic material. The support 4 serves two purposes: firstly, it stabilizes the frame 1, and secondly, it provides a good spatial environment for the installation of the display component 5.

[0029] Support 4 includes an upper plate, a connecting body, and a lower plate. The upper plate is circular with a circular opening in the middle. The lower plate has the same specifications and structure as the upper plate. The connecting body is a cylindrical hollow structure with openings on both the top and bottom. The upper end of the connecting body is fixed to the outer edge of the opening on the lower side of the upper plate by welding glue, and the lower end is fixed to the outer edge of the opening on the upper side of the lower plate by welding glue.

[0030] The height of the support 4 is equal to the height of the LCD screen 2 (including the upper and lower bezels 1), the outer diameter of the upper plate is equal to the inner diameter of the upper bezel 1, and the outer diameter of the lower plate is equal to the inner diameter of the lower bezel 1.

[0031] Installation steps for support 4: 1. Place support 4 into the inner cavity of the LCD screen 2 and then align it as required; 2. Bond and fix the joint between the upper plate and the upper frame 1; 3. Bond and fix the joint between the lower plate and the lower frame 1 so that support 4 and LCD screen 2 form a whole.

[0032] The lower plate of the support 4 is provided with display components 5 on both upper sides (as shown in the figure), and the display components 5 are kept at a distance of 3cm-4cm from the liquid crystal display screen 2.

[0033] The two display components 5 mentioned above are based on the fact that the liquid crystal display screen 2 is composed of two semi-cylindrical screens 6 (curved screens), or in other words, the liquid crystal display screen 2 is seamlessly spliced ​​together from at least two semi-cylindrical screens 6 (curved screens), and each screen 6 is independently equipped with a display component 5 at its rear.

[0034] The fact is, the larger the size of the load-bearing column 19, the larger the diameter of the LCD screen 2. Large-sized LCD screens 2 are generally made up of three to four semi-cylindrical screens 6 seamlessly spliced ​​together, while small-sized LCD screens 2 are usually made up of two semi-cylindrical screens 6 seamlessly spliced ​​together (see screen 6). Figure 3 ).

[0035] Please refer to Figure 3 The display component 5 mainly includes a housing, a diffuser plate 7, and a light-emitting diode array plate 8. Since the internal structure of each display component 5 is the same, this embodiment only describes one of them.

[0036] The shapes of the components shown in the accompanying drawings of this embodiment are only symbolically represented. In fact, the screen 6, the diffuser 7, and the LED array 8 are all curved surface structures, and their outer curvatures are consistent.

[0037] The screen 6 shown in the attached figure is only one component of the liquid crystal display screen 2. A complete liquid crystal display screen 2 is usually made up of at least two semi-cylindrical screens 6 (curved screens) seamlessly spliced ​​together.

[0038] The diffuser plate 7 and the light-emitting diode array plate 8 are assembled in sequence and placed inside the housing.

[0039] The diffuser plate 7, also known as a diffuser sheet, is mainly used to homogenize light distribution and ensure uniform brightness of the display screen. By uniformly dispersing light, it reduces the difference between bright and dark areas of the screen, thereby improving the visual effect.

[0040] Basic principle of light diffusion: The diffuser plate 7 is a PC substrate that has been frosted. It contains diffusers with a particle size of less than 5 micrometers. These diffusers can cause light to be refracted and diffused when passing through different media, thereby changing and expanding the light emission angle and making the plate surface a soft and uniform light emission surface.

[0041] A light-emitting diode array board 8 is a circuit board that integrates multiple light-emitting diode elements. It is mainly used to realize the display functions of numbers, symbols and graphics, and presents information by controlling the on and off of LED beads.

[0042] Core Structure and Control Principle: The LED matrix consists of LED beads arranged in rows and columns (e.g., 8×8, 16×32 specifications). Display is achieved by controlling the on / off state of individual LEDs. Each LED can be connected in either a common cathode or common anode configuration. Row control signals are connected to the cathode, and column control signals are connected to the anode.

[0043] LCD screen 2 driving principle: Through high-speed scanning (typically at a scanning frequency of GHz per line), a continuous image is formed by utilizing the persistence of vision in the human eye. Line scanning activates each line sequentially, with each line displaying for approximately 4ms; column scanning illuminates LEDs column by column within the same row.

[0044] LCD screen principle 2: Taking an 8×8 dot matrix as an example, lighting up a single dot sets the corresponding row to a high level and the column to a low level (e.g., pin 9 is high level and pin 13 is low level); to display Chinese characters, a 16×16 dot matrix is ​​required, which is achieved by combining 4 8×8 dot matrices. Each row of data needs to be scanned 16 times to be displayed completely.

[0045] Please refer to Figure 4 The liquid crystal display screen 2 is composed of at least two semi-cylindrical screen bodies 6 seamlessly spliced ​​together. Since each screen body 6 has the same structural specifications, this embodiment only describes one of them.

[0046] The screen body 6 includes a front polarizing film 9, a front glass substrate 10, a color filter 11, an electrode plate 12, an array film 13, a rear glass substrate 14, and a rear polarizing film 15, which are assembled together in a front-to-back sequence.

[0047] The following is a detailed description of each component to help you better understand their performance advantages and functions.

[0048] The front polarizing film 9 is usually attached to the outside of the front glass substrate 10. Its function is to analyze the polarized light after it has been modulated by the liquid crystal, to generate contrast between light and dark, and thus to produce a display image.

[0049] The front and rear glass substrates 10 serve as the basic platform for the liquid crystal display screen, mainly used for coating (attaching) and wrapping liquid crystal materials and electrode materials, and forming pixels and driving circuits on them.

[0050] The function of color filter 11 is to correct the color temperature and compensate for color temperature variations caused by different color temperatures. It generates the three primary colors (red, green, and blue) through filtering, and then produces various colors by mixing these three primary colors in different proportions.

[0051] Electrode plate 12: officially called common electrode, it is connected to the source of the thin film transistor and together with the transparent display electrode forms a charging electrode to charge the liquid crystal in each sub-pixel.

[0052] The array film 13 serves as a carrier for the TFTs, gate scan lines, and source array lines, and is typically disposed on the back glass substrate 14. The TFTs are primarily used to control whether the liquid crystal is charged. When a positive voltage is applied to the gate of the TFT and is greater than the applied voltage, the drain and source electrodes are turned on, charging the liquid crystal and the storage capacitor. When the positive gate voltage is equal to 0 or negative, the drain and source electrodes are turned off, stopping charging. The gate scan lines are primarily used to control the on / off state of the TFTs. By applying voltage to the gate scan lines, the corresponding TFTs are selectively turned on or off, thus controlling the charging state of the liquid crystal. The source array lines are primarily used to provide the charging voltage. When the TFTs are turned on, the voltage on the source array lines is transferred to the liquid crystal and the storage capacitor, thus charging the liquid crystal.

[0053] The rear polarizing film 15 is typically attached to the front side of the rear glass substrate 14. Its function is to absorb light perpendicular to the polarization axis, allowing only light parallel to the polarization axis to pass through, and converting natural light into linearly polarized light.

[0054] Please refer to Figure 5 and Figure 6 The LCD screen 2 in this application is a multi-dimensional advertising information display platform, which is usually installed on the outside of the load-bearing column 19 in the lobby, or on a pre-set cylindrical false column.

[0055] The load-bearing column 19 is connected to the ceiling 21 of the hall at the top and fixed to the ground at the bottom. The cylindrical sleeve 18 is a decorative sleeve on the outside of the load-bearing column 19 (cylinder), with a pre-reserved annular mounting port for the LCD screen 2 in its central section. The outer panel is made of alloy material. In addition, the outer side of the panel is also coated with a coating that coordinates with the interior decoration to enhance the aesthetics.

[0056] Since the outer diameter of the LCD screen 2 is the same as that of the cylindrical outer sleeve 18, their outer curvatures remain integrated or perfectly matched.

[0057] The cavity between the cylindrical outer sleeve 18 and the load-bearing column 19 is provided with annular hollow connectors 20 at both the top and bottom. The connectors 20 are preferably made of insulating material. The connectors are mainly used to reinforce the cylindrical outer sleeve 18, improve its impact or compression resistance, and ensure the stability of the liquid crystal display screen 2.

[0058] The upper and lower bezels 1 of the liquid crystal display screen 2 are fixed to the mounting opening in the middle section of the cylindrical outer sleeve 18 by hot-melt technology. The display system also includes a microcontroller 17, which is located on the lower side of one side of the upper connector 20, and both display components 5 are connected to the microcontroller 17 by wiring.

[0059] The 17-microcontroller is a C51 microcontroller, which integrates microelectronics, computer, automatic control, and communication technologies. It is primarily used for controlling data transmission, data processing, and graphic display of a monitor.

[0060] The 17-bit microcontroller mainly includes input / output interfaces (I / O), memory, clock circuit, communication module, LCD display driver circuit and output interfaces (I / O), etc.

[0061] The output interface is mainly used to transmit external electrical signals to the microcontroller 17 for processing. It has multiple connection ports, and one end of the output line of the display component 5 is fixed to one of these ports.

[0062] The memory is primarily responsible for storing the programs and data necessary for internal operations, including raw data that has been edited or entered, programs, intermediate results, and final results.

[0063] The processor is the core of a computer system for computation and control. It is responsible for reading instructions, decoding instructions, and executing instructions. It mainly consists of two parts: the control unit and the arithmetic logic unit (ALU).

[0064] The clock circuit is mainly used to provide a stable time base for the microcontroller and control the speed of instruction execution.

[0065] The communication module is mainly responsible for data transmission and wireless signal transmission and reception between devices or between devices and the external environment, which facilitates remote control and management of the display (updating advertising information).

[0066] The liquid crystal display driver circuit is mainly used to provide the necessary electrical signals to the liquid crystal display in order to control the alignment direction of the liquid crystal molecules, thereby realizing the display of images.

[0067] The output interface is mainly used to transmit internal signals to external devices. It has multiple connection ports distributed inside, and one end of the input line of display component 5 is fixed to one of these ports.

[0068] The above components work together to enable the microcontroller 17 to control the LCD display to work normally.

[0069] Implementation steps for controlling the LCD screen 2 using a single-chip microcomputer 17:

[0070] The first step is to write a program within the microcontroller 17 to process external information and convert it into a format suitable for display. This includes operations such as initializing the display, setting display parameters, and sending display data.

[0071] The second step is to transmit external information to the microcontroller 17 through a pre-defined interface and protocol.

[0072] The third step is for the microcontroller 17 to generate corresponding control signals based on the received external information. These signals are used to control the working mode of the display, such as turning on or off specific pixels.

[0073] Fourth, to maintain the visibility of the displayed content, the microcontroller 17 needs to refresh the display periodically. This typically involves periodically sending update data and control signals.

[0074] The microcontroller 17 and the computer 16 on the control console transmit information wirelessly.

[0075] Remote control and management of computer 16: Remote communication is achieved between computer 16 and the console via network protocols (such as TCP / IP). For example, an ESP8266 module is used to connect to a Wi-Fi network, and then the data sent by computer 16 is wirelessly forwarded to microcontroller 17 via the server's forwarding function.

[0076] The process of remote transmission of advertising information is as follows: The central computer 16 sends the edited advertising information or image data to the microcontroller 17 in the form of wireless transmission. After receiving the data, the communication module of the microcontroller 17 sends it to the memory. After the memory saves the data, it sends a command to drive the display. The processor executes the command and drives the LCD screen 2 to display the advertising content through the LCD display driver circuit.

[0077] Liquid crystal display (LCD) is a widely used technology that displays images by controlling the orientation of liquid crystal molecules with an electric current. It utilizes the special properties of liquid crystal screens to provide very high-quality, high-definition images.

[0078] The LCD screen 2 in this application adopts BSV LCD seamless splicing technology, which can realize the fusion of multiple screen images and minimize the splicing gap to the point of complete overlap.

[0079] Seamless splicing of LCD displays is a mature technology that can achieve single-screen split display, single-screen independent display, or combined shared display according to different usage needs. Furthermore, image borders can be compensated or masked, and it supports digital signal roaming, scaling, stretching, cross-screen display, and the setting and operation of various display presets.

[0080] The multi-angle visual digital media advertising display system provided by this utility model can solve the existing problems of narrow field of view and poor side view effect caused by the small dimension of the LCD screen. It effectively improves the display effect of advertising information content, and has a novel and beautiful design, stable performance and high degree of automation.
