With the rapid development of our country's LED display industry technology, the LED application market in various application places in life is fully launched. As an emerging energy-saving green outdoor high-density LED display, it is like a duck to water in the market. Walking on the street, there are conspicuous LED products everywhere. However, the brightness and chromatic aberration of outdoor high-density LED displays has also become the focus of users' attention. Below, LCF sends a small editor to introduce how to solve the specific "brightness and color difference"?
Under normal circumstances, the brightness of the outdoor high-density LED display must be above 1500cd/m2 to ensure the normal operation of the display, otherwise the displayed image will be unclear because the brightness is too low, and in a long-term high temperature environment It may cause LED attenuation. A circuit board that can meet the design requirements is manufactured, and the most common heat dissipation method is to use aluminum heat dissipation fins as part of the surgery to increase the heat dissipation area. The lowest cost way to enhance heat dissipation - use the shape of the lamp housing to create convective air.
The brightness of the outdoor high-density LED display is mainly determined by the quality of the LED lamp beads. Poor heat dissipation or uneven heat dissipation may cause the LED light to malfunction. In order to ensure that the color displayed on the LED display should be highly consistent with the color of the playback source. , the white balance effect is one of the most important indicators of the LED display. The size of the viewing angle directly determines the audience of the LED display, so the bigger the better. The uneven attenuation speed of the red, green and blue LED lights is more likely to cause a color cast on the screen. The size of the viewing angle is mainly determined by the packaging method of the die. Due to the different brightness of the LED lights, the entire screen will be blurred.
There are many types of outdoor high-density LED displays, such as outdoor energy-saving, high-brightness, high-refresh, portable and other products. All walks of life have different requirements for LED displays. Therefore, when users distinguish the quality of LED displays and choose LED displays, You need to combine your own needs to ensure that this product meets your needs to the greatest extent. In recent years, my country's LED application products have shown a situation of short supply, mainly driven by the demand for LED display, LED lighting and lighting. While our country's LED industry is rapidly advancing towards high-end applications, market competition is also becoming increasingly fierce.
