畢業(yè)設(shè)計(論文) 基于 LED 的廣告點陣顯示設(shè)計 學(xué) 院: 信息學(xué)院 專 業(yè): 姓 名: 指導(dǎo)老師: 自動化 陳燦展 學(xué) 號: 職 稱: 110104031010 齊連眾 實驗師 中國珠海 二○ 一五 年 六 月 誠信承諾書 本人鄭重承諾: 本人承諾呈交的畢業(yè)設(shè)計《 基于 led 的點陣廣告屏設(shè)計 》是在指導(dǎo)教師的指導(dǎo)下,獨立開展研究取得的成果,文中引用他人的觀點和材料,均在文后按順序列出其參考文獻,設(shè)計使用的數(shù)據(jù)真實可靠。 本人簽名: 陳燦展 日期: 20xx 年 6 月 6 日 基于 Led廣告顯示器的設(shè)計 摘 要 LED 顯示屏是新世紀很 關(guān)鍵的信息傳播媒體,在多個行業(yè)都有著關(guān)鍵的運用。很多超市外表裝修、銀行滾動提示屏、火車站售票點等, LED 顯示屏都無處不在。 LED 顯示屏最常見的結(jié)構(gòu),有的產(chǎn)品一出廠,廠家已經(jīng)把資料固定在里面,這樣設(shè)計價格相對比較低也比較精簡。也有著電子屏已經(jīng)有預(yù)留讀寫口,用戶購買之后,可以根據(jù)自己的需要,按照說明說靈活地修改自己需要的內(nèi)容,讓 LED 顯示屏更具靈活通用性。 關(guān)鍵詞: AT89C5 LED 矩陣顯示屏、單片機 Design of Led advertising display based on Abstract LED display is information media is the key of the new century, has a key to use in a variety of industries. Many supermarkets appearance decoration, bank rolling screen prompts,train station ticket points, LED displays are everywhere. The most mon structure of LED display screen, some products factory, manufacturers have fixed material inside, so the design relatively low price is also more streamlined. Also has an electronic screen hasreserved the readwrite port, the user after the purchase, can according to their own needs, in accordance with the instructions that modify the contents of their own needs, letLED display more flexible and universal.
