Abstract: This paper expatiates the principle of a intelligent display unit of 16×64 lattice and the principle founding a LED large screen display system by this unit. It describes the technique of realizing the real-time display and the corresponding block diagram of the software and hardware. It has been proved that our design idea is propitious to the standardization of the hardware production of the display unit and it also facilitates the hardware production. The design can also realize the function of the whole system by software.
