A Brief Discussion on the Four Basic Steps for Correctly Installing Outdoor LED Advertising Signs
Outdoor LED advertising billboards have advantages such as good stability, low energy consumption, and wide radiation range, making them the most suitable product for outdoor information dissemination. Common LED displays generally include advertising screens, strip screens, and graphic screens, which are also the preferred choice for city life and lighting.
When building high-quality outdoor LED advertisements, there are some important details to pay attention to. These are key concerns, especially for technical construction personnel. Understanding outdoor construction and maintenance of advertising screens effectively promotes the dissemination of business advertising and information. Specifically, the installation of outdoor LED electronic display screens involves four stages: on-site investigation, equipment setup, installation, and commissioning.
1. On-site Investigation
This refers to the pre-installation testing of outdoor LED display screens for specific environment, topography, radiation range, and brightness acceptance. To ensure smooth installation, a unified lifting plan must be implemented for the command personnel before lifting and installation to guarantee normal and stable operation of the equipment.
2. LED Equipment Setup
For outdoor LED advertising screens, it is necessary to differentiate between wall-mounted, suspended, and rooftop screens. During actual installation, depending on the height and distance, cranes and winches should be used for section-by-section hoisting, ensuring coordination among personnel. For high-altitude LED advertising screens, a better installation process should be followed.
3. Radiation Range Adjustment
Next, radiation range detection is carried out. Since the radiation range varies, the viewing angle of the LED display screen also varies. The outdoor LED display screen should be fixed according to the on-site acceptance capacity and common viewing range. This ensures normal and evenly bright images and subtitles are visible from all angles.
4. Subsequent Inspection and Maintenance
Subsequent inspections cover many aspects, such as waterproofing of the LED display screen, heat dissipation layer, LED surface waterproof coating, rain protection above the display screen, side heat dissipation spaces, power supply lines, etc. These basic components constitute a stable graphic LED display screen. Post-technical maintenance involves unified management and maintenance of these components. When rust, instability, or damage occurs, timely replacement is necessary to ensure safe operation of the entire display screen.
Overall, outdoor LED advertising screens, using high-tech backplane heat dissipation and dot matrix light source emission, are more conducive to screen use. These basic outdoor advertising screen installation steps highlight the important aspects of LED display screen installation. Understanding these steps allows for smoother and faster use of the advertising display screen, maximizing its excellent information dissemination capabilities.

What is LED full-color display screen testing technology?
With the increasing maturity of LED display technology and its wider application, LED full-color displays have become part of daily life. LED full-color displays can provide timely and effective advertising, news information, civilized transmission, video and image playback, etc. This document compiles LED full-color screen testing skills for learning and reference.
I. LED Full-Color Display Testing Standards:
In recent years, developed countries and governments in the US, Japan, and Europe have invested significant manpower and material resources in the development and research of LED lighting, leading to significant advancements in LED light source technology. LED light sources are now feasible for general lighting. LED products are set to become the leading energy-saving lighting products. However, LED lighting fixtures are high-tech, high-value-added products. China's previous research on LED lighting has been limited, with a significant gap compared to international levels, especially in application-based research, which cannot meet the needs of China's industrial development.
II. LED Full-Color Display Testing Content:
1. Radiation Bandwidth: The wavelength range where the spectral radiant power is greater than or equal to half of its value.
2. Half-Intensity Angle: In the luminous (or radiant) intensity distribution, the angle formed by the luminous (or radiant) intensity greater than or equal to half of the maximum intensity (LED light).
3. Reverse Current: The current flowing through the light-emitting diode when the reverse voltage applied across the light-emitting diode is a predetermined value.
4. Forward Voltage: The voltage drop across the anode and cathode when the forward current passing through the light-emitting diode is a predetermined value.
Summary: In today's information society, with continuously improving living standards, the demand for full-color LED displays is also increasing. How to solve common problems encountered in the application of LED full-color screens? Please refer to the testing parameters of LED full-color displays!

What is an LED grid screen? Do you understand?
LED grid display screen, zone, hollow, transparent product form, also known as curtain screen, screen curtain wall, etc., due to its light weight, small wind load, flexible installation, etc., it has more flexible applications, it is usually used for building exterior walls and stage LED rental screens. It is a new generation of outdoor LED display products, especially suitable for building ultra-large outdoor displays. LED large screen
Light weight, small wind load, suitable for large displays.
The weight is 60%-80% lighter than traditional LED displays, greatly reducing the strength and weight of the display infrastructure. Especially suitable for building ultra-large LED displays, with a popularity rate of 40%-50%. It has strong wind resistance. Effectively reduce wind load and further reduce the strength and weight of LED display infrastructure.
Simple structure, easy installation, easy maintenance.
Due to the fewer components, it can be easily attached to the wall without damaging the wall and foundation. Pre-maintenance or post-maintenance can be easily implemented as needed. If the pre-maintenance mode is adopted, no maintenance channel is required.
Good self-heating system, no need to install air conditioning for heat dissipation.
Each LED strip is made of aluminum alloy material, transparent on all sides, and can achieve good self-heat dissipation. At the same time, the power supply, control, etc. are isolated from the lighting materials, and there is no need to configure a heat dissipation system like traditional LED screens.
Highly integrated light rod structure, high product stability.
Unique electronic circuit design, reducing the number of light strips. Every 16 light strips share a set of power and signal plugs. Under the same conditions, the probability of blockage is reduced by 94%.
The control box is integrated with the installation structure.
The control box is both part of the screen and part of the structure. The screen structure is greatly simplified, and any connectors and wires are invisible in the screen. Not only beautiful, but also greatly improves the stability of the screen.
High brightness, high refresh rate, high gray scale, can be played during the day.
