LED全彩色显示屏顾名思义，就是由红色、绿色、蓝色3种发光二极管组成，led显示屏可以显示变化的数字、文字、图形图像；不仅可以用于室内环境还可以用于室外环境，具有投影仪、电视墙、液晶显示屏无法比拟的优点；亮度高、工作电压低、功耗小、小型化、寿命长、耐冲击和性能稳定。扫描场频达240HZ以上，画面稳定无闪烁，在实际应用中，用摄像机拍摄显示屏，摄像机中观测到的图像十分清晰，没有同步滚动条，若现场有电视传播，显示屏不会影响转播画面的画质。
As the name suggests, led full-color display screen is composed of red, green and blue light-emitting diodes. LED display screen can display changing numbers, words and graphics; It can be used not only in indoor environment, but also in outdoor environment. It has incomparable advantages over projectors, TV walls and LCD screens; High brightness, low working voltage, low power consumption, miniaturization, long service life, impact resistance and stable performance. The scanning field frequency is above 240Hz, and the picture is stable without flicker. In practical application, the camera is used to shoot the display screen, and the image observed in the camera is very clear without synchronous scroll bar. If there is TV transmission on site, the display screen will not affect the image quality of the broadcast picture.
