【正文】 later in the same show, and its essence is stored in a memory to be displayed in the ASCII character code, displayed by querying the corresponding character in the character library of information to determine the lattice points on the screen to be bright and dark is essentially A / NⅢAbstract display this paper, we pay attention to Alphabet/Number，A/ this paper, we pay attention to Alphabet/Number，A/ characters will be introduced and the principle will be will be later detailed representation ,the essence is in video memory storing an ASCII code of the characters to be displayed, is displayed by querying the corresponding characters in dot matrix characters in the information library to determine the points of the screen to be bright or dark order to adapt to technological development, deepen the understanding of related technologies on display some of this knowledge for I: Principles of display devices and a detailed of various display devices and display technologies related terms, describes the character and graphic display, and in contrast to the two displayed in so that we can display a deeper understanding and organizational form of the screen based on the detailed description of the screen and display the correspondence between the cache and display were bined with two , the screen display, internal display shows the correspondence between the counter at all II: In order to enhance intuitive understanding, this article specifically to achieve using FLASH A / N display demo, to show the reader a profound realization of the chapter discusses the A / N display FLASH Animation of involves the main points of the ponents to achieve animation, character animation realization matrix idea, and sort out the A / N display logic order to improve the animation process, we also added a FLASH on the play control, and some simple believe the reader understand the principles shown to help some intuitive Hope this article helps you point out irregularities in order to : Monitor Display mode Character ASCII code Dot matrixⅣ目 錄目 錄目

題目背景輸入輸出設(shè)備是計算機系統(tǒng)與人或其他設(shè)備、系統(tǒng)之間進行信息交互的裝置。希望本文對廣大讀者有所幫助。為了完善動畫演示過程，我們還在FLASH中加入了對播放的控制，以及一些簡單的腳本編寫。本章主要討論了A/N顯示方式演示動畫的FLASH實現(xiàn)。最后結(jié)合屏幕的顯示，展示了顯示器內(nèi)部各級計數(shù)器之間的對應(yīng)關(guān)系。了解各種顯示設(shè)備以及顯示技術(shù)的相關(guān)術(shù)語，介紹了字符和圖形兩種顯示方式，并在這兩種顯示方式的對比中讓大家對顯示器有更深的理解和認(rèn)識。為了適應(yīng)技術(shù)的發(fā)展，加深對相關(guān)技術(shù)的理解本文就顯示器的一些相關(guān)知識作詳細(xì)的論述。就如將在后面詳細(xì)展示一樣，其實質(zhì)是在顯存中存放一幀待顯示字符的ASCII碼，顯示時通過查詢相應(yīng)字符在字符庫中的點陣信息來確定屏幕上點的亮暗來得到顯示結(jié)果。目前的顯示都采用VGA以上的顯示模式，它們的同屏彩色數(shù)可在12516K、32K、64K、16M（所謂真彩色）直到4G中選擇。常用的顯示模式有CGA、EGA、VGA和SVGA（即TVGA）等等。顯示器顯示方式和顯示模式：就屏幕顯示畫面的點組織方式而言，顯示方式有兩種，即字符數(shù)字方式（Alphabet/Number，A/N）和全點尋址圖形方式（All Point Addressable，APA）。目前常見顯示器有陰極射線管CRT(Cathode Ray Tube)，發(fā)光二極管LED（Lighting Emitting Diode）和等離子顯示器PDP（Plasma Display Panel）液晶顯示器LCD（Liquid Crystal Display）,電化學(xué)反應(yīng)顯示等。我們打開電腦，從開機的字符提示到開機后的圖形化界面以及瀏覽圖片觀賞電影都是根據(jù)顯示器的輸出獲得信息。計算機設(shè)計與實踐就是從理論、抽象、設(shè)計三個方面將計算機系統(tǒng)內(nèi)部處理器、存儲器、控制器、運算器、外設(shè)等各個部分聯(lián)系起來，達到互相支撐、互相促進進。培養(yǎng)學(xué)生理論聯(lián)系實際的能力。建立整機概念，掌握自項向下的問題分析能力，既能理解系統(tǒng)各層次的細(xì)節(jié)，又能站在系統(tǒng)總體的角度從宏觀上認(rèn)識系統(tǒng)，然后將系統(tǒng)很好的分解為功能模塊。至少我不再像以前那樣對計算機什么也都不懂。計算機中的存儲器有哪些等等。還有就是控制單元的設(shè)計方法微程序設(shè)計，這個知識點也是不太懂，總的來說這門課程，學(xué)得不是很好。對于計算機運算方法，這個沒太搞懂，像定點運算中的乘法運算和除法運算，又
