摘要
基于LED点阵显示屏在当今交通领域内的广泛应用,提出改进目前车载显示屏显示效果的方案,以提高车载显示屏显示的动态效果与乘客观赏性。通过运用Proteus软件,并配合KeilC51编译器,依照实际中应用的车载显示屏情况,设计了分辨率达16×128的条型LED点阵显示屏进行仿真实验。采用单片机、移位寄存器、译码器等元件搭建了仿真电路原理图,列举说明了显示程序的设计方法。本设计实现了显示屏的多种动态效果,程序可针对硬件电路实际情况,较为方便地移植到实际的车载LED显示屏系统中。
Dot matrix LED display has been widely used in the transportation.A method is given to improve the dynamic effects of on-board LED display and its visual effect to the passengers.By using the Proteus software and KeiC51 compiler,a strip LED screen with 16×128 is designed for the simulation according to the actual on-board LED display.The simulation circuit is built based on SCM,shift register and decoder etc.Some of the display program design methods are described.This design realizes a variety of dynamic effects of the display,and the program can be easily ported to the actual on-board LED display system according to its hardware circuit.
