[0002] In recent years, although LED display technology has developed rapidly towards high integration, existing solutions still have significant technical bottlenecks.

[0003] Traditional LED display screens generally adopt a modular splicing structure, and their core cabinets (such as 600×337.5mm or 640×480mm specifications) mostly rely on die-cast aluminum or sheet metal materials, resulting in a single screen weight of more than 20kg / ㎡, posing a severe challenge to the wall's load-bearing capacity.

[0004] Taking high-end engineering screens as an example, the cabinet needs to integrate multiple components such as AC-DC power supply, receiving card and Hub adapter board. The internal wiring is complicated and relies on professionals to perform steel structure welding and leveling operations. The construction period is long and the cost is high. Although the low-cost channel screen simplifies the connection through soft cables and red and black wires, the signal crosstalk and unstable power transmission caused by this seriously threaten the system life and safety.

[0005] In addition, traditional solutions are limited by fixed-size cabinet designs (e.g., the maximum size of a home TV is ≤110 inches), making it impossible to expand the display area as needed, and the entire machine needs to be replaced when it is partially damaged, resulting in a waste of resources.

[0006] Therefore, how to solve the problems of unstable signal transmission, inflexible size expansion and global replacement due to local damage has become a technical problem that needs to be solved urgently. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] The embodiments of the present application provide an indoor small-pitch integrated drive LED ultra-thin display screen to solve the following technical problems: how to solve the problems of unstable signal transmission, inflexible size expansion, and global replacement of local damage.

[0021] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0022] Figure 1 This is a schematic diagram of an indoor small-pitch integrated drive LED ultra-thin display system. Figure 1 As shown, an indoor small-pitch integrated drive LED ultra-thin display system provided in an embodiment of the present application specifically includes: an external main control module, a first-level signal module, a screen body module, a longitudinal series module and a cross-column series module.

[0023] The external main control module is connected to the first-level signal module via a network cable for signal distribution and power management; the first-level signal module is connected to the screen module via a split floating hard connector to achieve signal and power distribution; the screen module is composed of multiple independent display units, and adjacent display units are connected into vertical display unit groups through vertical series modules, and the vertical display unit groups are spliced ​​into a complete screen through cross-column series modules.

[0024] The external main control module includes the main control unit, the sending unit, the OPS computer unit and the power management unit, and is the control core of the entire system.

[0025] The main control unit is responsible for receiving external signals, such as LVDS, DP, HDMI, SDI, etc., and generating control instructions and audio and video data.

[0026] As an optional accessory, the OPS computer unit provides computer attributes for this application, realizing the two-in-one function of home and commercial use.

[0027] The power management unit is responsible for providing stable power input to the entire system.

[0028] like Figure 2 As shown, the sending unit includes an input interface group, an output interface group, a main control chip and a display control chip, which are used to process the signal of the main control unit and distribute it to the primary signal module.

[0029] The input interface group includes a power supply interface, a USB interface, a DP interface and an HDMI interface.

[0030] Among them, the sending unit also includes an MCU processor, a relay chip, a level conversion chip, a USB adapter chip and a transceiver chip; the USB interface is connected to the MCU processor through the USB adapter chip; the USB interface is connected to the transceiver chip through the transformer chip, and the transceiver chip is connected to the MCU processor; the HDMI interface is connected to the main control chip through the level conversion chip and the relay chip.

[0031] The main control chip is an ICND6620 chip, which is connected to the display control chip via a board-level HDMI signal, and the display control chip is an ICND6603 chip.

[0032] In the embodiment of the present application, the USB adapter chip adopts the CH347T chip, the voltage transformer chip adopts the HR641680E transceiver chip, the transceiver chip adopts the IP101GR transceiver chip, and the level conversion chip adopts the DDC levels shifter chip.

[0033] The sending unit also includes a CD4051 chip and a CH440R chip. The CH440R chip is connected to the MCU processor and the CH347T chip to receive instructions from the MCU processor and USB signals transmitted from the USB interface. The CD4051 chip is connected to the CH440R chip to select instructions from the MCU processor or USB signals to the ICND6620 chip.

[0034] The output interface group is connected to the ICND6603 chip, wherein one output interface is connected to one ICND6603; if there are multiple output interfaces, multiple ICND6603 chips are included, and the number of the output interfaces is the same as the number of the ICND6603 chips.

[0035] The primary signal module is connected to the sending unit via a network cable, and includes a signal conversion unit and a communication interface. The signal conversion unit converts the control instructions and audio and video data of the main control unit into drive signals that can be recognized by the screen module. The communication interface is used to send these drive signals to the screen module. The screen module includes multiple display units, each of which includes a housing and an LED light board. The housing can be made of carbon fiber, die-cast aluminum, aluminum alloy, magnesium alloy, carbon steel and other materials to provide solid protection.

[0036] For different environments, different materials can be used for the shell. For example, carbon fiber material has the characteristics of high strength and light weight, which is suitable for occasions with strict weight requirements; die-cast aluminum material has excellent heat dissipation performance and is suitable for high-brightness and long-term use environments; magnesium alloy material has good electromagnetic shielding properties and is suitable for occasions with high requirements for electromagnetic interference.

[0037] The light board is responsible for displaying images and video content. The pixel pitch of the LED light board of this application supports multiple specifications such as 0.6, 0.7, 1.0, 1.2, 1.5, 1.8, 2.0, 2.5 mm, etc., and can be configured with real pixels or virtual pixels to meet the needs of different resolutions and clarity.

[0038] At the same time, LED types also include SMD three-in-one, SMD four-in-one, virtual pixel lamp beads, upright COB lamp beads, flip-chip COB and other options to adapt to different display effects and application environments.

[0039] The vertical series module is used to connect adjacent display units to form a vertical display unit group. The cross-column series module is used to connect adjacent vertical display unit groups to form a complete screen module. Both modules support wiring and hard connection to meet different installation requirements.

[0040] Flat cable connection: Flat cable connection uses soft flat cable, which is convenient for wiring in narrow space and is suitable for occasions with high space requirements.

[0041] Hard connection: Hard connection uses a sturdy metal connector, which can ensure stable signal transmission and reliable connection to a certain extent, and is suitable for occasions with high requirements on signal quality.

[0042] The workflow of this application includes: After receiving external signals, the main control unit of the external main control module generates control instructions and audio and video data. The main control chip of the sending unit analyzes these signals and generates distribution instructions. The display control chip converts the distribution instructions into drive signals and sends them to the primary signal module through the output interface group; The signal conversion unit of the primary signal module converts the received drive signal to adapt to the needs of the screen module. The communication interface sends the converted signal to the screen module; After the display unit of the screen module receives the driving signal, the LED light board displays the corresponding image and video according to the signal content.

[0043] The power management unit provides stable power input for the entire system. The primary signal module and the vertical / cross-column series module are responsible for distributing power to each display unit to ensure the normal operation of the system.

[0044] Installation of this application: The indoor small-pitch integrated driver LED ultra-thin display provided in this application supports multiple installation methods, such as nailing directly to the wall, hanging with a bracket, or vertically installing with a vertical bracket. This design greatly simplifies the installation process and reduces the professional requirements for the installer.

[0045] For example, for a flat wall, you can directly use the pre-drilled holes on the shell to install it, and then install the LED light board; For another example, in the case of an extremely uneven wall, the present application only requires marking with ink lines and installing a hanging bracket every 1.5 square meters, and then assembling the display unit and finally hanging it on the hanging bracket.

[0046] Since the present application adopts a modular design, when there is local damage, only the corresponding module needs to be replaced instead of all the modules, thereby reducing maintenance costs and time.

[0047] Through the above-mentioned specific implementation methods, the indoor small-pitch integrated drive LED ultra-thin display provided by this application achieves the characteristics of high integration, light weight, quick installation and strong expandability, effectively solving the technical problems of unstable signal transmission, inflexible size expansion and global replacement in case of local damage.
