畢業(yè)設(shè)計(jì)(論文) 基于 LED 的廣告點(diǎn)陣顯示設(shè)計(jì) 學(xué) 院: 信息學(xué)院 專 業(yè): 姓 名: 指導(dǎo)老師: 自動(dòng)化 陳燦展 學(xué) 號(hào): 職 稱: 110104031010 齊連眾 實(shí)驗(yàn)師 中國(guó)珠海 二○ 一五 年 六 月 誠(chéng)信承諾書(shū) 本人鄭重承諾: 本人承諾呈交的畢業(yè)設(shè)計(jì)《 基于 led 的點(diǎn)陣廣告屏設(shè)計(jì) 》是在指導(dǎo)教師的指導(dǎo)下,獨(dú)立開(kāi)展研究取得的成果,文中引用他人的觀點(diǎn)和材料,均在文后按順序列出其參考文獻(xiàn),設(shè)計(jì)使用的數(shù)據(jù)真實(shí)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(jì) 摘 要 LED 顯示屏是新世紀(jì)很 關(guān)鍵的信息傳播媒體,在多個(gè)行業(yè)都有著關(guān)鍵的運(yùn)用。很多超市外表裝修、銀行滾動(dòng)提示屏、火車(chē)站售票點(diǎn)等, LED 顯示屏都無(wú)處不在。 LED 顯示屏最常見(jiàn)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(jì)價(jià)格相對(duì)比較低也比較精簡(jiǎn)。也有著電子屏已經(jīng)有預(yù)留讀寫(xiě)口,用戶購(gòu)買(mǎi)之后,可以根據(jù)自己的需要,按照說(shuō)明說(shuō)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(jī) 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.
