一、電容筆和觸控筆的區別
電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)是(shi)利用導(dao)體材(cai)料制(zhi)作的(de)(de)(de)具(ju)(ju)有的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)特性(xing)，用來(lai)在(zai)觸(chu)(chu)控(kong)(kong)(kong)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)式(shi)屏(ping)(ping)幕完成(cheng)人機對(dui)話操作用的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)，是(shi)利用導(dao)體材(cai)料模(mo)仿人體（通常是(shi)手指）完成(cheng)人機對(dui)話一種輔助(zhu)裝(zhuang)置。觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)一種小筆(bi)(bi)(bi)(bi)(bi)形的(de)(de)(de)工具(ju)(ju)，用來(lai)輸入指令到電(dian)(dian)(dian)(dian)(dian)(dian)腦屏(ping)(ping)幕、移動設(she)備(bei)(bei)、繪(hui)(hui)圖板等(deng)(deng)具(ju)(ju)有觸(chu)(chu)摸屏(ping)(ping)的(de)(de)(de)設(she)備(bei)(bei)，用戶可以通過觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)點擊觸(chu)(chu)控(kong)(kong)(kong)屏(ping)(ping)幕來(lai)選(xuan)取文件(jian)或繪(hui)(hui)畫。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和(he)觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)兩者(zhe)的(de)(de)(de)區別在(zai)導(dao)體材(cai)料、作用機制(zhi)和(he)適(shi)(shi)(shi)用對(dui)象的(de)(de)(de)不(bu)同(tong)(tong)：電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)頭帶(dai)有靜電(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)幕本身有感應(ying)靜電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)技術特點，所以電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)；而(er)普通的(de)(de)(de)觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)靠按壓(ya)屏(ping)(ping)幕，適(shi)(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和(he)觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)哪個好，寫字繪(hui)(hui)畫用哪種筆(bi)(bi)(bi)(bi)(bi)主(zhu)要要根據選(xuan)擇的(de)(de)(de)產(chan)品來(lai)看，不(bu)同(tong)(tong)的(de)(de)(de)屏(ping)(ping)幕適(shi)(shi)(shi)應(ying)不(bu)同(tong)(tong)的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)：觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)主(zhu)要適(shi)(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)(ping)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)，現在(zai)的(de)(de)(de)平板、手機等(deng)(deng)設(she)備(bei)(bei)基本上都是(shi)用的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)，因此一般(ban)現在(zai)用電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)比(bi)較多(duo)。
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(dian)容筆的(de)防誤觸(chu)功能、延遲、筆尖材質(zhi)、續航能力、有無(wu)壓(ya)感功能等(deng)方面(mian)。
三、電容筆怎么連接平板
電(dian)容(rong)筆(bi)分為被動(dong)(dong)式(shi)(shi)電(dian)容(rong)筆(bi)和主動(dong)(dong)式(shi)(shi)電(dian)容(rong)筆(bi)，被動(dong)(dong)式(shi)(shi)電(dian)容(rong)筆(bi)可(ke)(ke)(ke)(ke)以直接(jie)(jie)用，主動(dong)(dong)式(shi)(shi)電(dian)容(rong)筆(bi)內置芯片，需要連(lian)(lian)(lian)接(jie)(jie)才能使用，連(lian)(lian)(lian)接(jie)(jie)方法很簡單：1、將手寫(xie)筆(bi)放在平板(ban)附(fu)近，拉下狀態欄(lan)，將藍牙(ya)(ya)打開，再長按(an)“藍牙(ya)(ya)”，進入藍牙(ya)(ya)界(jie)面。2、這(zhe)時，藍牙(ya)(ya)會自動(dong)(dong)彈(dan)出(chu)連(lian)(lian)(lian)接(jie)(jie)界(jie)面，點擊“連(lian)(lian)(lian)接(jie)(jie)”即可(ke)(ke)(ke)(ke)，如果沒有(you)彈(dan)出(chu)，也可(ke)(ke)(ke)(ke)以在藍牙(ya)(ya)搜(sou)索界(jie)面里找到手寫(xie)筆(bi)的ID，然(ran)后連(lian)(lian)(lian)接(jie)(jie)。3、連(lian)(lian)(lian)接(jie)(jie)好后，手寫(xie)筆(bi)就可(ke)(ke)(ke)(ke)以使用了(le)。
四、電容筆是干什么用的
電容(rong)筆(bi)(bi)在最初出現(xian)的(de)(de)時候(hou)，較(jiao)為(wei)普遍地使用(yong)(yong)在部分(fen)帶有觸(chu)屏功能(neng)(neng)的(de)(de)手(shou)機上，可(ke)以用(yong)(yong)電容(rong)筆(bi)(bi)進(jin)(jin)行(xing)操作(zuo)(zuo)，用(yong)(yong)于操作(zuo)(zuo)對應的(de)(de)屏幕上方功能(neng)(neng)按鈕，以達到使用(yong)(yong)者的(de)(de)目的(de)(de)。由(you)于當時技術并不先進(jin)(jin)，導致手(shou)機及平板(ban)很多功能(neng)(neng)未被開(kai)發(fa)出來，而使得電容(rong)筆(bi)(bi)的(de)(de)用(yong)(yong)途(tu)受(shou)到較(jiao)大的(de)(de)局限(xian)，不過現(xian)如今(jin)不管(guan)是硬件還是軟件技術都得到跨越性的(de)(de)提升，電容(rong)筆(bi)(bi)的(de)(de)用(yong)(yong)途(tu)更(geng)加廣泛(fan)。現(xian)如今(jin)，隨著更(geng)多App的(de)(de)較(jiao)完(wan)善(shan)的(de)(de)功能(neng)(neng)開(kai)發(fa)，讓電容(rong)筆(bi)(bi)的(de)(de)功能(neng)(neng)也(ye)(ye)產生(sheng)質的(de)(de)改變(bian)，不再只(zhi)是用(yong)(yong)于觸(chu)控操作(zuo)(zuo)這(zhe)么簡單。現(xian)如今(jin)電容(rong)筆(bi)(bi)已(yi)經可(ke)以直接(jie)在移動設備，如手(shou)機、筆(bi)(bi)記(ji)本、平板(ban)等(deng)，利用(yong)(yong)APP的(de)(de)功能(neng)(neng)開(kai)展工作(zuo)(zuo)，比如進(jin)(jin)行(xing)繪畫、制圖、更(geng)正或者標注文檔等(deng)，也(ye)(ye)可(ke)對相(xiang)關會議或談(tan)話現(xian)場進(jin)(jin)行(xing)快速記(ji)錄(lu)等(deng)。
五、電容筆的工作原理
要(yao)知(zhi)道電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)的(de)工(gong)作(zuo)原理，首(shou)先(xian)要(yao)了解與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)配套使用(yong)(yong)(yong)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)的(de)原理：電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)是(shi)利用(yong)(yong)(yong)人(ren)體(ti)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)感應工(gong)作(zuo)的(de)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)觸(chu)(chu)摸(mo)屏(ping)利用(yong)(yong)(yong)人(ren)體(ti)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)感應進行(xing)工(gong)作(zuo)，當手(shou)(shou)指(zhi)(zhi)觸(chu)(chu)摸(mo)在金(jin)屬層上時，由(you)于(yu)人(ren)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)場、用(yong)(yong)(yong)戶(hu)和觸(chu)(chu)控屏(ping)表(biao)面形成(cheng)以一(yi)個(ge)耦合電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，對于(yu)高頻電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)來說(shuo)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)是(shi)直(zhi)接導體(ti)，于(yu)是(shi)手(shou)(shou)指(zhi)(zhi)從接觸(chu)(chu)點吸走一(yi)個(ge)很小的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。這(zhe)(zhe)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)分別從觸(chu)(chu)控屏(ping)四(si)(si)角上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)中流(liu)(liu)出(chu)(chu)，并且流(liu)(liu)經這(zhe)(zhe)四(si)(si)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)與(yu)手(shou)(shou)指(zhi)(zhi)到(dao)四(si)(si)角的(de)距離(li)成(cheng)正比，控制器通過對這(zhe)(zhe)四(si)(si)個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)比例的(de)精確計(ji)(ji)算，得出(chu)(chu)觸(chu)(chu)摸(mo)點的(de)位(wei)置(zhi)信息(xi)。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)就是(shi)通過導體(ti)模擬人(ren)體(ti)手(shou)(shou)指(zhi)(zhi)，筆(bi)(bi)尖觸(chu)(chu)摸(mo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)時同(tong)樣產生電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，控制器對電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)計(ji)(ji)算得出(chu)(chu)觸(chu)(chu)摸(mo)信息(xi)，并完成(cheng)操作(zuo)。
