電子書閱讀器的優點
一書多用:一本電子書閱讀器可(ke)以裝載很多本電子版(ban)的圖(tu)書。大多數產品(pin)可(ke)以擴(kuo)充SD卡(ka)/CF卡(ka)等大容量存(cun)儲,可(ke)以作為一(yi)個小型的移動(dong)圖(tu)書館。部分產品(pin)還(huan)可(ke)以作為筆(bi)記本、資(zi)料夾(jia)使用。
省電環保:電子書(shu)閱讀器用電極省,不使用傳(chuan)統紙張,由于(yu)使用了先進的顯(xian)示(shi)技(ji)術,可以幫助人(ren)們少(shao)買紙質書(shu),減少(shao)砍伐樹木,從而保護(hu)了環境(jing)。
保護視力:新(xin)型(xing)電子書閱讀器的顯示原理與(yu)目前的電腦和手機不同,不是主(zhu)動發(fa)光,而是與(yu)傳統紙張一樣(yang)靠反射(she)自然(ran)光或燈光,因此無(wu)輻射(she),不刺(ci)眼,對(dui)視力(li)無(wu)損傷(shang)。
海量存儲:目前的(de)電(dian)子(zi)閱讀器大多可以擴充外置存儲卡,可以存儲高達8G,16G的(de)數字圖書,擁有一本電(dian)子(zi)書閱讀器,相當擁了一個小(xiao)型的(de)圖書館。
電子書閱讀器比手機、PDA 、筆記本電(dian)(dian)(dian)腦(nao)、PSP、MP3等的優越性: 電(dian)(dian)(dian)子(zi)書閱(yue)(yue)(yue)(yue)讀(du)(du)(du)器(qi)與它們的區(qu)別是(shi)專業(ye)閱(yue)(yue)(yue)(yue)讀(du)(du)(du)與非專業(ye)閱(yue)(yue)(yue)(yue)讀(du)(du)(du)之分(fen)。電(dian)(dian)(dian)子(zi)書閱(yue)(yue)(yue)(yue)讀(du)(du)(du)器(qi)有(you)自已的閱(yue)(yue)(yue)(yue)讀(du)(du)(du)格式(shi),可以分(fen)章節(jie)、加(jia)書簽;電(dian)(dian)(dian)池繼航(hang)時間,閱(yue)(yue)(yue)(yue)讀(du)(du)(du)界面明顯優越于(yu)手(shou)(shou)機、PDA等。閱(yue)(yue)(yue)(yue)讀(du)(du)(du)的舒適性、方便性和可持久性占優。電(dian)(dian)(dian)子(zi)書閱(yue)(yue)(yue)(yue)讀(du)(du)(du)器(qi)和軟件(jian)(jian)電(dian)(dian)(dian)子(zi)書閱(yue)(yue)(yue)(yue)讀(du)(du)(du)器(qi)相(xiang)比,軟件(jian)(jian)通常需要(yao)安裝在電(dian)(dian)(dian)腦(nao)上(shang)或者手(shou)(shou)機上(shang)才能閱(yue)(yue)(yue)(yue)讀(du)(du)(du),不專業(ye),不方便。而電(dian)(dian)(dian)子(zi)書閱(yue)(yue)(yue)(yue)讀(du)(du)(du)器(qi)是(shi)一個已經集成了閱(yue)(yue)(yue)(yue)讀(du)(du)(du)軟件(jian)(jian)的硬件(jian)(jian)設(she)(she)備(bei),隨著發展,這(zhe)一個設(she)(she)備(bei)所集成的功能也(ye)越來越多。比如手(shou)(shou)寫、批注(zhu)、朗讀(du)(du)(du)、網(wang)絡等等!
閱讀器工作原理
電(dian)(dian)(dian)(dian)子(zi)書閱(yue)讀器采用電(dian)(dian)(dian)(dian)子(zi)紙作為顯示屏(ping),有多種技術,一(yi)般(ban)使用所謂“電(dian)(dian)(dian)(dian)泳”的(de)技術,即:在微小膠囊中灌注極(ji)小的(de)白(bai)色(se)(se)顆粒(li),加電(dian)(dian)(dian)(dian)后白(bai)色(se)(se)顆粒(li)浮(fu)游到(dao)(dao)表明,顯示白(bai)色(se)(se),否則顯示黑色(se)(se)或(huo)藍色(se)(se),從而達到(dao)(dao)顯示圖文的(de)目的(de)。白(bai)色(se)(se)顆粒(li)到(dao)(dao)位置(zhi)后,即使撤掉電(dian)(dian)(dian)(dian)壓,它們也會保持在該位置(zhi),因(yin)此不需(xu)持續(xu)加電(dian)(dian)(dian)(dian),只在變換內容時才用電(dian)(dian)(dian)(dian),因(yin)此非常省電(dian)(dian)(dian)(dian)。
