机械与材料工程学院本科毕业论文（设计） 题 目 一种小型 LED 点阵显示系统设计 专业班级 2025 级测控技术与仪器一班 学 号 学生姓名 指导老师 设计所在单位 2025 年 5 月一种小型 LED 点阵显示系统设计摘要:伴随着科技的进步，LED 点阵显示屏作为一种新兴的显示器件走进我们的视野，它是由多个独立的 LED 发光二极管封装而成。通过 LED 点阵显示屏可以显示数字、符号以及文字，通常用在广告，指示牌，公告牌上。本设计利是一种基于 STC89C52 单片机的 16*16 点阵显示屏的设计，其中STC89C52 单片机负责对整个系统进行总体控制，设计中使用 4 块 8*8 单红色点阵屏来组成 16*16 点阵屏，通过三极管来控制点阵的行方向的控制，而列方向的控制采纳两片串行输入八位并行输出的 74LS595 级联来控制，通过快速的动态刷新来显示我们需要的内容，已达到动态显示的目的。关键词：点阵；单片机；译码器；动态扫描The system design of a small LED dot matrix displayAbstract:With advances in technology, LED dot matrix display as a display device into our new vision, it is more independent of the LED light emitting diode packages. LED dot matrix display can show by numbers, symbols and text, often used in advertising, signs, bulletin boards.The design is based on STC89C52 Lee microcontroller 16 * 16 dot matrix display design, which is responsible for the entire chip STC89C52 overall control system design using four 8 * 8 to form a single red dot-matrix screen 16 * 16 points front panel, through the decoder to control the direction of the control line dot matrix, and the column direction is controlled by two serial input parallel output of the 74LS595 eight cascaded to control, through a fast dynamic refresh to show that we need content, has reached the dynamic display purposes.Keywords: lattice；MCU； decoder； dynamic scanning目录第 1 章 绪论.........................................................................................................................
