Problems solved by technology

In rainy days, the LED display screen is wetted by rain, and people's eyes can easily induce eye diseases and cause light source pollution when people's eyes are facing the display screen at close range for a long time. The impact on the mental aspect, too high brightness will also affect people's normal life and work
At present, the traditional LED display control system has a narrow working range, cannot monitor and adjust the display screen in many ways, and has low work efficiency. In view of this, it is necessary to study an LED control system based on an ARM microprocessor.

Description

technical field [0001] The invention belongs to an LED display screen control system, in particular to an LED control system based on an ARM microprocessor. Background technique [0002] The LED display is a flat panel display, which is composed of small LED module panels and is used to display various information such as text, images, videos, and video signals. LED displays are widely used in advertising in stadiums, banks, shopping malls, schools, hotels, and other outdoor venues. In rainy days, the LED display screen is wetted by rain, and people's eyes can easily induce eye diseases and cause light source pollution when people's eyes are facing the display screen at close range for a long time. The impact on the mental aspect, too high brightness will also affect people's normal life and work. At present, the traditional LED display control system has a narrow working range, cannot monitor and adjust the display in various aspects, and has low work efficiency. In view ...
