LED16×16點陣漢字顯示屏

摘要 :
LED點陣顯示屏是利用發(fā)光二極管點陣模塊或像素單元組成的平面式顯示屏幕。它具有發(fā)光效率高、使用壽命長、組態(tài)靈活、色彩豐富以及對室內(nèi)外環(huán)境適應(yīng)能力強(qiáng)等優(yōu)點。并廣泛的應(yīng)用于公交汽車，碼頭，商店，學(xué)校和銀行等公共場合的信息發(fā)布和廣告宣傳。LED顯示屏經(jīng)歷了從單色，雙色圖文顯示屏到現(xiàn)在的全彩色視頻顯示屏的發(fā)展過程，自20世紀(jì)八十年代開始，LED顯示屏的應(yīng)用領(lǐng)域已經(jīng)遍布交通、電信、教育、證券、廣告宣傳等各方面。
LED點陣顯示屏可以顯示數(shù)字或符號，通常用來顯示時間、速度、系統(tǒng)狀態(tài)等。文章給出了一種基于MCS-51單片機(jī)的16×16 點陣LED顯示屏的設(shè)計方案。包括系統(tǒng)具體的硬件設(shè)計方案,軟件流程圖和部分C語言程序等方面。在負(fù)載范圍內(nèi), 只需通過簡單的級聯(lián)就可以對顯示屏進(jìn)行擴(kuò)展,是一種成本低廉的圖文顯示方案。
本設(shè)計主要以AT89C51單片機(jī)為核心，采用串行傳輸、動態(tài)掃描技術(shù)，制作一款擁有顯示漢字的模塊化LED多功能顯示屏。

LED16 x 16 bitmap characters display screen
Abstract  Destem is using light emitting diode matrix modules or pixel unit composed of a flat display screen. It has high luminous efficiency, long service life, configure, flexible, colour is rich and for indoor and outdoor environment adaptiveness, etc. And widely used in transit buses, wharf, stores, schools and bank, public information release and advertising. The LED display experienced from monochrome, double-color graphic display to now full-color video display the development process, since the 1980s began, LED display applications has already spread transportation, telecommunication, education, securities, advertising, etc.

Destem can display Numbers, or symbols, usually to show time, speed, the system state, etc. The paper gives a method based on MCS - 51 SCM 16 x 16 lattice LED display design scheme. Including the system design scheme of concrete hardware and software flow chart and part C language program, etc. In load range, only through simple cascade can expand on screen, is a low-cost graphic display solutions.

This design mainly AT89C51, using a serial transmission, dynamic scanning techniques, making a paragraph of modularization LED display characters with multi-function screen.
