The influence of full-color LED module parameters on the performance of full-color LED screens

The full-color LED large screen module is the key part of the display screen. It is equipped with an LED circuit board and a shell. It is a product composed of LED lamp beads arranged according to certain rules and then waterproofed. With the continuous development of the full-color LED large screen industry and the increasing application demand, the function and role of the LED module have become more and more important. The full-color LED large screen for stage rental has the characteristics of anti-collision, light and thin, convenient installation, fast maintenance, and high waterproof performance.

The performance parameters that affect the full-color LED large screen module are mainly the following points, and the color of the LED module is the basic parameter. Next, Shenzhen Hengcai Optoelectronics analyzed the impact of LED module parameters on the full-color LED large screen.

1. Brightness of full-color LED large screen module: When it comes to brightness, we easily think of the word high brightness, and this parameter is a parameter that everyone is very concerned about. Brightness is a more complicated issue in full-color LED large screens. In LED modules, the brightness usually referred to is usually the sum of luminous intensity and transparency, which is usually the sum of the degrees associated with each module.

2. Color of full-color LED large-screen module: Color is the basic parameter of LED module. In different scene applications, different LED module colors are selected according to scene requirements. According to the color type, it can be divided into monochrome and true color point control: 1. Monochrome is a single color, which cannot be changed and can work by connecting the power supply; 2. True color points can control the color of each module. When the number of modules reaches a certain level, the color points can achieve the effect of displaying photos and videos. The full color points can only achieve the effect by adding a control system.

3. The luminous angle of the full-color LED large-screen module: The luminous angle of the LED module without a lens is mainly determined by the LED lamp beads. Different LED lamp beads have different luminous angles. Usually, the luminous angle of the LED lamp beads provided by the factory is the angle of the LED module.

4. Full-color LED large screen module size: generally refers to the length, width and height dimensions, which are the standard dimensions of a single module. This parameter is more commonly used in large-scale engineering projects. The number of modules required for the entire display screen should be calculated based on the module size. This is related to the size of the LED module’s connection line. It should be tailored according to the actual situation.

5. Full-color LED large screen module voltage: a very important parameter in LED modules. Currently, 5V low-voltage modules are more common. When connecting the power supply and control system, turn on the power supply and make sure the voltage value is correct. Otherwise, the LED module may be damaged due to voltage exceeding the range.

6. Working temperature of full-color LED large screen module: The working temperature of LED module is usually between -18 and 58. If the required range is relatively high, special treatment is required, and the temperature should be controlled within the normal working temperature range by using air conditioning or exhaust fan.

7. Waterproof grade of full-color LED large screen module: This is an important indicator to ensure whether the LED module can work for a long time outdoors. Generally, the waterproof grade of outdoor full-color LED large screen module must reach IP65.
