With the rapid development of technology in our country's LED display screen industry, the LED application market in various application places in daily life is fully launched. As an emerging energy-saving and green outdoor high-density LED display screen, it is like a fish in water in the market. Walking on the streets, there are eye-catching LED products everywhere. However, the brightness and color difference of outdoor high-density LED displays have also become a focus of attention for users.
In general, the brightness of outdoor high-density LED displays should be above 1500cd/m2 to ensure normal operation of the display screen. Otherwise, the displayed image may not be clear due to low brightness, and LED attenuation may occur in long-term high-temperature environments. Produce circuit boards that meet design requirements, and the most common heat dissipation method is to use aluminum heat dissipation fins as a part of the shell to increase the heat dissipation area. The lowest cost way to enhance heat dissipation is to use the shape of the lamp housing to create convective air.
The brightness of outdoor high-density LED displays is mainly determined by the quality of LED beads. Poor or uneven heat dissipation may cause LED lights to malfunction. To ensure that the color displayed on the LED display screen is highly consistent with the color of the playback source., The white balance effect is one of the most important indicators of LED display screens. The size of the visual angle directly determines the audience of the LED display screen, so the larger the better. The uneven attenuation speed of the red, green, and blue LED lights is more likely to cause color deviation on the screen. The size of the visual angle is mainly determined by the packaging method of the tube core, and due to the different brightness of LED lights, it can cause the entire screen to be blurred.
There are a wide variety of outdoor high-density LED display screens, including energy-saving, high brightness, high refresh, and portable products. Various industries have different requirements for LED display screens. Therefore, users need to consider their own needs when distinguishing between good and bad LED display screens and selecting LED display screens to ensure that this product meets their needs to the greatest extent possible. In recent years, the supply of LED application products in China has been in short supply, mainly driven by the demand for LED displays, LED lighting, and lighting. As China's LED industry rapidly advances towards high-end applications, market competition is also becoming increasingly fierce.
