Selection points:
In these scenarios, the audience is far away from the display, so special attention needs to be paid to pixel size and brightness.
A larger pixel size can maintain the clarity of the picture at a long distance, while high brightness can ensure that it can still be displayed clearly in strong light environments, such as direct sunlight, and not be overwhelmed by ambient light.
2). 輝度 and color
2.1). Indoor LED display:
Brightness range: Generally controlled at around 800-2000cd to avoid excessive brightness causing visual discomfort to the audience.
Color requirements: The colors need to be bright and highly saturated to ensure that the picture is rich and vivid and enhance the audience’s viewing experience.
2.2). Outdoor LED display:
Brightness requirements: It needs to reach 2000-6000cd to cope with the complex outdoor light environment and ensure that it can still be displayed clearly under direct sunlight.
Color requirements: High contrast and vividness are required to maintain color accuracy and clarity under strong light and avoid color distortion or blur.
3). Cost Control
Budget considerations: Choose the appropriate LED display model and specifications according to the activity budget to ensure the best display effect within limited funds.
Long-term costs: In addition to the purchase cost, the later maintenance cost of the display needs to be considered, including energy consumption, repair costs, etc. Choosing a display with high energy efficiency and low maintenance costs will help reduce long-term operating costs.
4). Flexibility and portability
- Scenario requirements:
For activities that require frequent venue changes or temporary construction (such as exhibitions, celebrations, etc.), it is particularly important to choose LED displays that are easy to carry, transport, and disassemble.
These displays are usually designed with lightweight frames and quick installation systems, which can complete the construction and disassembly work in a short time, improving the efficiency of the event.
- モジュール設計：
Consider choosing a modularly designed LED display, which allows users to freely combine and splice display units according to actual needs to adapt to venues of different sizes and shapes. At the same time, modular design also helps to reduce transportation and storage costs and improve the flexibility and practicality of the display.
3. Choose the right type of LED display
Generally, when holding an event, people like to use rental LED display screens. Rental LED screens are designed for stage performances, literary and artistic activities, etc. They have the characteristics of repeated disassembly and installation, ultra-light and ultra-thin, space-saving, and splicing in any direction and size.
They usually use SMD surface mount three-in-one packaging technology, which can achieve ultra-wide viewing angles to meet different needs.
However, there are many common types of rental LED screens. How to choose?
P5, P6, P10, and other specifications, with high transparency, are suitable for scenes that require transparent or translucent display effects, such as glass curtain walls, stage backgrounds, etc.
- Rental LED full-color screens:
Including P4, P5, P6, and other specifications, can display rich colors and delicate pictures. It is the most common type in the rental market and is suitable for various indoor and outdoor performances and event sites.
It is composed of flexible soft modules or realized by rotating splicing of conventional modules. It is suitable for scenes that require curved display effects, such as LED cylindrical screens, spherical LED screens, etc. It has a unique shape and strong rendering power. It is suitable for large-scale events and exhibitions that require unique visual effects.
4. Consider other factors
When choosing an LED display, in addition to the key factors mentioned above, there are some other factors that are also worth paying attention to, which have an important impact on the performance and user experience of the display.
