The intelligent multi-layer rotation function combines the rapid response characteristics of MNLED technology (gray scale response time <1ms) to present the exhibits in a smooth and novel way. The audience can clearly view them from different angles through the wide-angle curved screen, enhancing the visiting experience and interactivity. Sex, helping cultural dissemination and knowledge popularization.
Enterprises set up MNLED intelligent mechanical screens in the exhibition hall to display the corporate image in all aspects.
企业在展厅中设置 MNLED 智能机械屏，可全方位展示企业形象。It supports the HDR10 + high dynamic range display standard. When displaying image data, core products and technical details of the company's development history, the bright parts of the picture are not exposed and the dark parts have details, vividly demonstrating the company's strength. Flexible screen combination and rotation mode, combined with the low latency characteristics of MNLED technology, ensure seamless connection of display content, leave a deep impression on customers and partners, and enhance the company's brand image and competitiveness.
In the high-end hotel lobby, MNLED smart mechanical screens enhance the hotel's style with their exquisite display effect.
在高端酒店大堂，MNLED 智能机械屏以其精致的显示效果提升酒店格调。It supports 4K ultra-high definition resolution, and when playing hotel promotional videos, event information, welcome words and other content, the picture is clear and sharp. The unique appearance and cool display effect, combined with the comfortable eye protection features brought by MNLED technology (no strobe, low blue light), provide guests with a high-end, luxurious and comfortable stay experience.
(1) Display selection
It adopts an indoor P3-specification LED soft module based on MNLED technology. The module specification is 320x160 and 27 displays are standard.
采用基于 MNLED 技术的室内 P3 规格 LED 软模组，模组规格为 320x160，标配 27 块显示屏。The micron-scale chip packaging process of MNLED technology makes the picture under P3 dot spacing appear more delicate than traditional LEDs. The characteristics of the soft module allow it to adapt to the curved shape. In conjunction with the uniform backlight design of the MNLED, it ensures that the display effect of the entire screen is even without dead spots, achieving 178 full-angle high-definition display.
（二）旋转与控制设备
- Rotation mode: It provides a total of eight rotation modes: positive and negative spiral/deformation, cross/deformation, semi-synchronous/deformation, and synchronous/deformation. Combined with the precise light control capabilities of MNLED technology, the brightness and color of the picture are always consistent under different rotation modes, enhancing the diversity of display effects.
- Rotation speed: Supports adjustable function, which can accurately adjust the running speed according to user needs or screen rhythm. The rapid response characteristics of MNLED ensure that the picture has no smear or afterimage when rotating at high speed, making the best match between the picture display and atmosphere creation.
- Control equipment: Equipped with advanced control system, it supports remote switching and publishing operations through computers and mobile phones. The MNLED display supports hardware decoding of mainstream image and video formats, allowing users to update and manage screen content anytime and anywhere, greatly improving the convenience and efficiency of operation.
Support 220V/380V power supply access, users can select the appropriate power supply type according to the actual situation on site.
支持 220V/380V 电源接入，用户可根据现场实际情况选择合适的电源类型。At the same time, it supports network cable or wifi network connection. The MNLED display has a built-in high-speed data processing chip to ensure stable and smooth data transmission when large data is transmitted, such as 4K video playback and multi-screen synchronous display, providing reliable guarantee for remote control and screen transmission.
(1) Installation preparation
（一）安装准备
- Before the equipment arrives at the site, it is necessary to ensure that the installation site has sufficient space and the ground is flat to withstand the equipment weight of approximately 1750kg. The MNLED display adopts a lightweight packaging design, which ensures display performance while reducing the overall weight of the equipment and is convenient for handling and installation.
- Plan the direction of power supply and network lines in advance, and route the power supply and network cables provided by users to ground troughs as required to ensure that the lines are safe and tidy. Taking into account the power demand characteristics of MNLED equipment, the load is reasonably planned during wiring to ensure stable operation of the equipment.
- Prepare a motorized forklift for handling and installation of equipment.
(2) Installation process
- Use a motorized forklift to carefully transport the equipment to the installation position to ensure that the equipment is stably placed on the configured chassis, and no additional base installation is required, simplifying the installation process.
- Connect the power supply and network lines, and conduct wiring operations in strict accordance with electrical specifications to ensure that the connection is firm and free from looseness. Professional connection and debugging are carried out for the special interface of MNLED display to ensure stable signal transmission.
- Conduct equipment debugging and check whether the display effect, rotation function, and control function of the display screen are normal. Use the intelligent calibration system that comes with the MNLED display to automatically calibrate the color, brightness, contrast and other parameters of the picture to ensure the best display state; test various rotation modes and speeds to ensure smooth operation and no abnormal noise.
