无线LED点阵显示装置设计i

A. 电子课程设计—LED点阵驱动电路设计

进我空间有答案，这东西嘛，很义贼。
[email protected]..各位大侠，加油咯！

B. 全彩LED显示屏想达到无线控制怎么设计

基本上实事控制的无法做到。

可以使用一种方案，就是用无线机顶盒，具体传输距离要看无线机顶盒的支持程度了。

D. 基于51单片机的LED点阵显示屏系统的设计与实现的论文

LED显示器是用发光二极管构成的显示器。构成方式有两大类：一是笔段字符式，一般又有三种：7段（/8段）数码管、15段（/17段）数码管和6段符号显示器；二是点阵字符式，一般有5×7、5×8、8×8和16×16等若干种点阵结构。为了适应不同电路的需要，根据构成LED显示器的发光二极管公共极的极性，有共阴极和共阳极两种形式。对共阴极数码管，公共阴极接地，当各段阳极上的电平为高电平时，该段接通亮，电平为0时，该段关断不亮。对共阳极数码管则刚好相反，高电平时不亮，低电平时亮。这种器件根据显示数位分类，可以分为一位、双位和多位LED显示器，一位LED显示器就称作LED数码管，两位以上的一般就称作LED显示器。
要实现LED的汉字显示在进行、列的扫描的同时还要对其进行供电，因为每行16个二极管点亮电流很大，普通芯片的输出电流远不能满足。下面为你提供实例参考
以16×16显示器为例，你可以用并行扩展芯片8255实现点阵的行扫描，8255可以将单片机一个8位并行I/O口扩展成16位（8255的PA口、PB口同时使用）；列扫描的16位可以用两个TTL门74LS164(8位移位寄存器)，74LS164再接ULN2803以对电流放大后再接16×16点阵。74LS164的移位触发端A、B可以接上一片的相邻输出端，Q1或Q7这样实现能实现多个芯片连续移位，以实现显示屏汉字从右到左或从左到右的移动显示功能。
由于网络知道不能插入图片，所以不提供图片了，将具体引脚接法告诉你：8255的D0--D7数据输入端接单片机P2.0--P2.7(任一并行I/O口)，A0接P2.0，A1接P2.1,/WR接单片机的/WR,/RD接高电平，如果单片机资源足够，则片选端/CS接低电平；74LS164芯片的触发端A、B接到一起，与CK脚、CLK脚、随意接到单片机的I/O上。

H. 是大神的请进，想要自学LED点阵屏的设计和应用需要掌握哪知识也必需知道什么知识

1、按应用环境分为户内，户外及半户外显示屏 户内LED
显示屏一般都不是很大，面积一般从不到1平米到十几平米,点密度较高，在非阳光直射或灯光照明环境使用，观看距离在几米以外，屏体不具备密封防水能力。户内显示屏以点阵模块为主，因为在户内使用对显示屏亮度要求不高，采用点阵模块具有很高的性价比。所以价格比较高。 户外LED
显示屏可大可小，面积一般从几平米到几十甚至上百平米根据客户需求不同，点密度较稀(多为1000-4000点每平米)，发光亮度在3000-6000cd/平米(朝向不同，亮度要求不同)，可在阳光直射条件下使用，观看距离在几十米以外，屏体具有良好的防风抗雨及防雷能力。 半户外LED
显示屏介于户外及户内两者之间，具有较高的发光亮度，可在非阳光直射户外下使用，屏体有一定的密封，一般在屋檐下或橱窗内。 2、按颜色分为单色显示屏，双色显示屏，三色也就是全彩LED
显示屏 单色是指显示屏只有一种颜色的发光材料，多为单红色。 双色屏一般由红色和黄绿色发光材料构成。 三色屏分为全彩色(full color)，由红色，绿色(波长570nm)，蓝色构成；及真彩色(nature color)，由红色，纯绿色(波长525nm)，蓝色构成。 3、 按控制方式分同步和异步 同步方式是指LED显示屏的工作方式基本等同于电脑的监视器，它以至少30场/秒的更新速率点点对应地实时映射电脑监视器上的图像，通常具有多灰度的颜色显示能力，可达到多媒体的宣传广告效果。 异步方式是指LED屏具有存储及自动播放的能力，在PC机上编辑好的文字及无灰度图片通过串口或其他网络接口传入LED屏，然后由LED屏脱机自动播放，一般没有多灰度显示能力，主要用于显示文字信息，可以多屏联网。 4、 按点间距像素划分 目前，常见的户内屏点阵屏有：P4，P5，P6，P7.62，P8，P10。户内屏的像素直径基本上不会超过10mm。主要原因是可视距离小及图像显示效果。 户外屏的像素直径及像素间距目前没有十分统一的标准，按每平米像素数量大约有2500点、3086点、3906点、5102点等。户外屏常见 有：P10，P12，P16，P20，P25。基本上都以LED灯直插模组为主。户外屏因为要克服光照影响，需要LED灯亮度高。同时显示屏可视距离有与 像素直径有关，因此户外屏基本上都是P10以上。 5、根据实现性能
LED显示屏按显示性能分为：单色图文屏、双色图文屏、双基色视屏、同步显示屏、三基色视屏（全彩色屏）、单色条屏、双色条屏、行情显示屏、各种显示牌等。行情LED显示屏一般包括证券、利率、期货等用途的LED显示屏，用来显示信息，公告等。 （1）文本显示屏，只能显示文字，支持txt。 （2）图文显示屏：支持TXT、BMP等文件，可显示简单的平面图画。同时也具备脱机运行功能，如果显示内容不更改，可不打开控制机,直接打开屏体 电源就行，显示方式支持展开、瞬间等十多种方式。内容停留可在0-255秒之间任意调节(含静止)，可自动循环显示用户要显示的不同内容，分为长驻、暂 驻、实时三种,制作后通过RS232和RS485串口发送到屏幕显示。 （3）视频显示屏：显示内容实时同步，可方便随意地选择显示画面的大小，颜色变化组合共256X256X256=16,777,216种，扫描场频 大于200赫兹，人肉眼几乎看不出扫描线，实现伽玛高速，无灰度损失的校正设计，参数可由用户选择，轻松地实现各种灰度级调节和亮度控制功能，使图像色彩 柔和逼真,较好地重现图像的层次和立体感，使LED在各种环境光线下呈线最佳显示效果。配备先进、完善的控制、制作和播放软件，易学易用，具有几十种播放 方式，可播放视频信息，具备计算机开关机自动黑屏功能，提高了显示屏的使用寿命，更避免了计算机开关机时，显示屏界面杂乱无意． （4）条屏：通常为一行或两行单色或双色，可使用专用遥控器．具脱机运行功能，即在显示内容编辑制作完成并发送至显示屏后可关闭控制机。显示内容存 储方式有长驻、暂驻和实时三种，可滚动显示不同内容，能显示4000个汉字，制作完后一般通过RS232串口方式发送到屏幕，并通过遥控器进行控制。通讯 线采用双绞线，抗干扰能力强，100米内通信距离使用RS232接口,100-500米内使用RS485接口。
