Abstract: In view of problems that large-scale LED electronic display screen used in surface has high power consumption and ca't be used in coal mine underground, the paper proposed a design scheme of mine-used LED array display screen with mosaic type. It gave structure of the display screen and introduced design of hardware and software of the display screen in details. The display screen not only can be used singly, but also can be used with information guiding system of coal mine. The debugging and test results showed that the display screen can receive and display figure and letter sent by upper computer real-timely and reaches prospective goal.
