一、電容筆和觸控筆的區別
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)是(shi)(shi)利用(yong)(yong)(yong)導(dao)體(ti)材(cai)料(liao)制作的(de)(de)(de)具(ju)有(you)(you)的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)特(te)性，用(yong)(yong)(yong)來在觸控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)屏(ping)幕(mu)完成人機對話(hua)操作用(yong)(yong)(yong)的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)，是(shi)(shi)利用(yong)(yong)(yong)導(dao)體(ti)材(cai)料(liao)模仿人體(ti)（通(tong)常是(shi)(shi)手(shou)指(zhi)）完成人機對話(hua)一(yi)種輔(fu)助(zhu)裝置。觸控(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)(shi)一(yi)種小筆(bi)(bi)(bi)(bi)(bi)形(xing)的(de)(de)(de)工具(ju)，用(yong)(yong)(yong)來輸入指(zhi)令到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦屏(ping)幕(mu)、移動(dong)設備(bei)、繪圖板等(deng)具(ju)有(you)(you)觸摸屏(ping)的(de)(de)(de)設備(bei)，用(yong)(yong)(yong)戶可以(yi)通(tong)過觸控(kong)筆(bi)(bi)(bi)(bi)(bi)點(dian)擊觸控(kong)屏(ping)幕(mu)來選(xuan)(xuan)取文(wen)件或繪畫(hua)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)和觸控(kong)筆(bi)(bi)(bi)(bi)(bi)兩者的(de)(de)(de)區別(bie)在導(dao)體(ti)材(cai)料(liao)、作用(yong)(yong)(yong)機制和適用(yong)(yong)(yong)對象的(de)(de)(de)不(bu)同(tong)：電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)頭帶有(you)(you)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)幕(mu)本身有(you)(you)感應靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)技(ji)術特(te)點(dian)，所以(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)適用(yong)(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)；而普通(tong)的(de)(de)(de)觸控(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)(shi)靠按壓屏(ping)幕(mu)，適用(yong)(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)和觸控(kong)筆(bi)(bi)(bi)(bi)(bi)哪(na)個好(hao)，寫字繪畫(hua)用(yong)(yong)(yong)哪(na)種筆(bi)(bi)(bi)(bi)(bi)主要要根據(ju)選(xuan)(xuan)擇的(de)(de)(de)產品(pin)來看，不(bu)同(tong)的(de)(de)(de)屏(ping)幕(mu)適應不(bu)同(tong)的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)：觸控(kong)筆(bi)(bi)(bi)(bi)(bi)主要適用(yong)(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)適用(yong)(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)，現在的(de)(de)(de)平板、手(shou)機等(deng)設備(bei)基本上都(dou)是(shi)(shi)用(yong)(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)，因此一(yi)般現在用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)比較多。
二、電容筆是什么平板都可以用嗎
電容筆對于操作平板電腦來說還是比較方便的，尤其是對需要經常在平板上寫寫畫畫的人來說，很多朋友比較關心電容筆的兼容性，其實一般來說，只要是電容屏的產品，電容筆都是通用的，因為電容屏的使用原理是一樣的，電容筆的使用原理也都是一樣，被動式電容筆可以用在所有電容屏產品上，只是效果可能有一些差異。另外，有的品牌的電容筆不是被動電容筆，而是內部有芯片的主動式電容筆，需要藍牙連接才能使用的，這種不一定可以通用，因此建議大家看看自家平板是什么品牌，然后買同品牌的電容筆。購買電容筆的時候，除了注意電容筆品牌外，還要注意考慮電容筆的防誤觸(chu)功能(neng)(neng)、延(yan)遲、筆尖材質、續航(hang)能(neng)(neng)力(li)、有(you)無壓感功能(neng)(neng)等方面。
三、電容筆怎么連接平板
電(dian)容(rong)筆(bi)分為被動(dong)式(shi)(shi)(shi)電(dian)容(rong)筆(bi)和主(zhu)動(dong)式(shi)(shi)(shi)電(dian)容(rong)筆(bi)，被動(dong)式(shi)(shi)(shi)電(dian)容(rong)筆(bi)可(ke)(ke)以(yi)直接(jie)用(yong)，主(zhu)動(dong)式(shi)(shi)(shi)電(dian)容(rong)筆(bi)內置芯片，需要連接(jie)才能使用(yong)，連接(jie)方法很簡單：1、將(jiang)手寫(xie)筆(bi)放在(zai)平板附近，拉下狀態欄，將(jiang)藍(lan)牙打開，再(zai)長按“藍(lan)牙”，進(jin)入藍(lan)牙界(jie)面。2、這時，藍(lan)牙會(hui)自動(dong)彈出連接(jie)界(jie)面，點擊“連接(jie)”即可(ke)(ke)，如果(guo)沒有彈出，也可(ke)(ke)以(yi)在(zai)藍(lan)牙搜索界(jie)面里(li)找到手寫(xie)筆(bi)的ID，然(ran)后(hou)連接(jie)。3、連接(jie)好后(hou)，手寫(xie)筆(bi)就可(ke)(ke)以(yi)使用(yong)了。
四、電容筆是干什么用的
電容(rong)(rong)筆在(zai)最初出現(xian)的(de)(de)時(shi)候，較為普遍地使(shi)用(yong)在(zai)部分(fen)帶(dai)有(you)觸(chu)屏功(gong)能的(de)(de)手機(ji)上，可以(yi)用(yong)電容(rong)(rong)筆進行操作，用(yong)于(yu)(yu)操作對應(ying)的(de)(de)屏幕(mu)上方功(gong)能按鈕，以(yi)達到(dao)使(shi)用(yong)者的(de)(de)目的(de)(de)。由于(yu)(yu)當時(shi)技(ji)術(shu)并不(bu)先進，導(dao)致手機(ji)及(ji)平板(ban)很多功(gong)能未被開(kai)(kai)發出來，而(er)使(shi)得(de)(de)電容(rong)(rong)筆的(de)(de)用(yong)途(tu)受到(dao)較大的(de)(de)局限(xian)，不(bu)過現(xian)如(ru)今不(bu)管是硬(ying)件還是軟(ruan)件技(ji)術(shu)都(dou)得(de)(de)到(dao)跨越性(xing)的(de)(de)提升，電容(rong)(rong)筆的(de)(de)用(yong)途(tu)更加廣泛。現(xian)如(ru)今，隨著更多App的(de)(de)較完(wan)善的(de)(de)功(gong)能開(kai)(kai)發，讓(rang)電容(rong)(rong)筆的(de)(de)功(gong)能也(ye)產生質的(de)(de)改變(bian)，不(bu)再只(zhi)是用(yong)于(yu)(yu)觸(chu)控操作這么簡單。現(xian)如(ru)今電容(rong)(rong)筆已(yi)經可以(yi)直(zhi)接在(zai)移動(dong)設備(bei)，如(ru)手機(ji)、筆記本、平板(ban)等，利用(yong)APP的(de)(de)功(gong)能開(kai)(kai)展工(gong)作，比如(ru)進行繪畫(hua)、制(zhi)圖、更正或(huo)者標注文檔等，也(ye)可對相關會(hui)議或(huo)談(tan)話現(xian)場進行快速記錄等。
五、電容筆的工作原理
要知道電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆的(de)(de)(de)工(gong)作原(yuan)(yuan)理(li)，首先(xian)要了(le)解(jie)與電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆配(pei)套使用的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)的(de)(de)(de)原(yuan)(yuan)理(li)：電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)是利用人(ren)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)感(gan)應(ying)工(gong)作的(de)(de)(de)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)觸摸(mo)(mo)屏(ping)利用人(ren)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)感(gan)應(ying)進行工(gong)作，當手(shou)指觸摸(mo)(mo)在金(jin)屬層上(shang)時，由于(yu)人(ren)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)場、用戶和觸控屏(ping)表面形成(cheng)(cheng)以(yi)一個(ge)耦合電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)，對(dui)于(yu)高頻電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)來說，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)是直接導體(ti)(ti)，于(yu)是手(shou)指從(cong)(cong)接觸點吸走一個(ge)很小的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。這個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)分別從(cong)(cong)觸控屏(ping)四(si)角上(shang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)中流(liu)(liu)出(chu)，并且(qie)流(liu)(liu)經這四(si)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)與手(shou)指到(dao)四(si)角的(de)(de)(de)距離成(cheng)(cheng)正比(bi)，控制(zhi)器(qi)通(tong)過(guo)對(dui)這四(si)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比(bi)例的(de)(de)(de)精確計算，得(de)出(chu)觸摸(mo)(mo)點的(de)(de)(de)位(wei)置信(xin)息(xi)。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)筆就是通(tong)過(guo)導體(ti)(ti)模(mo)擬(ni)人(ren)體(ti)(ti)手(shou)指，筆尖觸摸(mo)(mo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)時同樣產生電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，控制(zhi)器(qi)對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)計算得(de)出(chu)觸摸(mo)(mo)信(xin)息(xi)，并完成(cheng)(cheng)操作。
