资料介绍

双色LED点阵屏相对于单色LED点阵屏来说色彩丰富很多,动态显示更加能吸引人眼球。本文深入研究了双色LED点阵屏的工作原理,以STC12C5A60S2单片机为控制核心,每种基色都用8片74HC595串接进行列控制,2片74HC138组成4-16线译码器扫描来控制,设计制作出了16*64双色LED点阵屏。双色LED点阵屏能以三种不同的颜色滚动显示,设计的电路安全可靠,性价比高。

Compared with monochrome LED dot matrix screen,dual-color LED dot matrix screen has a lot of colors,and dynamic display is more eye-catching. In this paper,the working principle of dual-color LED dot matrix screen is deeply studied. With STC12C5A60S2 as the control core,each basic color is controlled by eight pieces of 74HC595 in series. Two pieces of 74HC138 form a 4-16 line decoder to scan and control. A 16*64 dual-color LED dot screen is designed and manufactured. Dual-color LED dot matrix screen can be displayed in three different colors. The designed circuit is safe and reliable with high cost performance.
