With the wide application of LED display in all walks of life, a variety of environmental factors on display around the real-time monitoring, environmental brightness monitoring-LED display brightness to adjust the design to achieve real-time changes in the brightness of the monitor display surrounding environmentand brightness values for statistical analysis, to remove the outliers and statistical analysis, automatic correction algorithm processing, and then need to adjust the brightness information is sent to the LED control system for the LED display brightness. Environmental brightness monitoring-LED display brightness to adjust the design to achieve the automatic adjustment of screen brightness to follow changes in the surrounding brightness, not only can reduce energy consumption, while avoiding the display brightness set too high, too low to cause viewing discomfort, thereby enhancinclthe viewina of the disolav.%随着LED显示屏在各行各业的的广泛应用，需要对显示屏周边的各种环境因子进行实时监测。环境亮度监测一LED显示屏亮度调整的设计实现可以实时监测显示屏周边环境亮度的变化，并将采样的亮度值进行处理，去除其中的异常值进行自动校正算法处理，而后再把需要调整的亮度信息发送到LED控制系统进行LED显示屏亮度调节。环境亮度监测-LED显示屏亮度调整的设计实现显示屏亮度跟随周边亮度的变化的自动调节，既可以降低能源消耗，同时可以避免因显示屏亮度设定过高、过低而导致的观看不适。从而提高显示屏的观看效果。
