一、電容筆和觸控筆的區別
電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)是(shi)利用(yong)導體(ti)(ti)材(cai)料(liao)制(zhi)作的(de)具有的(de)導電(dian)(dian)(dian)(dian)(dian)特(te)(te)性，用(yong)來在觸(chu)控(kong)電(dian)(dian)(dian)(dian)(dian)容式(shi)屏(ping)(ping)幕完(wan)成(cheng)人機對(dui)話操作用(yong)的(de)筆(bi)(bi)(bi)(bi)，是(shi)利用(yong)導體(ti)(ti)材(cai)料(liao)模仿(fang)人體(ti)(ti)（通常是(shi)手指(zhi)）完(wan)成(cheng)人機對(dui)話一(yi)種輔助裝置。觸(chu)控(kong)筆(bi)(bi)(bi)(bi)是(shi)一(yi)種小筆(bi)(bi)(bi)(bi)形的(de)工具，用(yong)來輸入(ru)指(zhi)令到電(dian)(dian)(dian)(dian)(dian)腦屏(ping)(ping)幕、移動設(she)(she)備、繪圖板(ban)等具有觸(chu)摸屏(ping)(ping)的(de)設(she)(she)備，用(yong)戶可以通過觸(chu)控(kong)筆(bi)(bi)(bi)(bi)點擊觸(chu)控(kong)屏(ping)(ping)幕來選取(qu)文件或(huo)繪畫(hua)。電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)和(he)觸(chu)控(kong)筆(bi)(bi)(bi)(bi)兩者的(de)區別在導體(ti)(ti)材(cai)料(liao)、作用(yong)機制(zhi)和(he)適用(yong)對(dui)象的(de)不同：電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)頭帶有靜電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)容屏(ping)(ping)幕本(ben)(ben)身有感(gan)應靜電(dian)(dian)(dian)(dian)(dian)的(de)技(ji)術特(te)(te)點，所以電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)適用(yong)于電(dian)(dian)(dian)(dian)(dian)容屏(ping)(ping)；而普通的(de)觸(chu)控(kong)筆(bi)(bi)(bi)(bi)是(shi)靠按壓屏(ping)(ping)幕，適用(yong)于電(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)和(he)觸(chu)控(kong)筆(bi)(bi)(bi)(bi)哪個好，寫(xie)字繪畫(hua)用(yong)哪種筆(bi)(bi)(bi)(bi)主要(yao)要(yao)根據(ju)選擇(ze)的(de)產(chan)品(pin)來看，不同的(de)屏(ping)(ping)幕適應不同的(de)筆(bi)(bi)(bi)(bi)：觸(chu)控(kong)筆(bi)(bi)(bi)(bi)主要(yao)適用(yong)于電(dian)(dian)(dian)(dian)(dian)阻(zu)屏(ping)(ping)，電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)適用(yong)于電(dian)(dian)(dian)(dian)(dian)容屏(ping)(ping)，現在的(de)平板(ban)、手機等設(she)(she)備基本(ben)(ben)上都是(shi)用(yong)的(de)電(dian)(dian)(dian)(dian)(dian)容屏(ping)(ping)，因此一(yi)般現在用(yong)電(dian)(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)(bi)比較多(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(wai)，還要(yao)注意(yi)考(kao)慮電容筆(bi)的防誤觸功能、延遲(chi)、筆(bi)尖(jian)材質、續航能力、有無壓感功能等(deng)方(fang)面。
三、電容筆怎么連接平板
電(dian)容筆(bi)(bi)分(fen)為被(bei)(bei)動式(shi)電(dian)容筆(bi)(bi)和(he)主動式(shi)電(dian)容筆(bi)(bi)，被(bei)(bei)動式(shi)電(dian)容筆(bi)(bi)可(ke)以直接(jie)(jie)用(yong)，主動式(shi)電(dian)容筆(bi)(bi)內置芯片，需(xu)要(yao)連(lian)(lian)接(jie)(jie)才能使(shi)用(yong)，連(lian)(lian)接(jie)(jie)方法很簡單：1、將手(shou)寫筆(bi)(bi)放在平(ping)板附近，拉(la)下(xia)狀態欄，將藍牙(ya)打開(kai)，再長按(an)“藍牙(ya)”，進入藍牙(ya)界(jie)面(mian)。2、這(zhe)時，藍牙(ya)會自(zi)動彈出(chu)連(lian)(lian)接(jie)(jie)界(jie)面(mian)，點(dian)擊“連(lian)(lian)接(jie)(jie)”即可(ke)，如(ru)果(guo)沒有彈出(chu)，也可(ke)以在藍牙(ya)搜索界(jie)面(mian)里找到手(shou)寫筆(bi)(bi)的(de)ID，然后(hou)(hou)連(lian)(lian)接(jie)(jie)。3、連(lian)(lian)接(jie)(jie)好后(hou)(hou)，手(shou)寫筆(bi)(bi)就(jiu)可(ke)以使(shi)用(yong)了(le)。
四、電容筆是干什么用的
電(dian)容(rong)(rong)(rong)筆(bi)在最初出現(xian)(xian)(xian)的(de)時候，較(jiao)(jiao)為普遍(bian)地使(shi)用(yong)(yong)在部(bu)分帶有(you)觸(chu)屏功(gong)(gong)能的(de)手機上，可以用(yong)(yong)電(dian)容(rong)(rong)(rong)筆(bi)進行(xing)(xing)操作(zuo)(zuo)，用(yong)(yong)于(yu)操作(zuo)(zuo)對(dui)應的(de)屏幕上方功(gong)(gong)能按鈕，以達到(dao)使(shi)用(yong)(yong)者的(de)目的(de)。由(you)于(yu)當時技術(shu)(shu)并不(bu)先(xian)進，導(dao)致手機及平板很多功(gong)(gong)能未被開發出來，而使(shi)得電(dian)容(rong)(rong)(rong)筆(bi)的(de)用(yong)(yong)途(tu)受到(dao)較(jiao)(jiao)大的(de)局(ju)限(xian)，不(bu)過現(xian)(xian)(xian)如今(jin)不(bu)管(guan)是硬件(jian)(jian)還是軟(ruan)件(jian)(jian)技術(shu)(shu)都得到(dao)跨越性的(de)提升，電(dian)容(rong)(rong)(rong)筆(bi)的(de)用(yong)(yong)途(tu)更加廣泛。現(xian)(xian)(xian)如今(jin)，隨著更多App的(de)較(jiao)(jiao)完善的(de)功(gong)(gong)能開發，讓(rang)電(dian)容(rong)(rong)(rong)筆(bi)的(de)功(gong)(gong)能也產生質的(de)改(gai)變，不(bu)再(zai)只是用(yong)(yong)于(yu)觸(chu)控操作(zuo)(zuo)這么簡單(dan)。現(xian)(xian)(xian)如今(jin)電(dian)容(rong)(rong)(rong)筆(bi)已(yi)經可以直接(jie)在移(yi)動設備，如手機、筆(bi)記(ji)本、平板等(deng)，利用(yong)(yong)APP的(de)功(gong)(gong)能開展工(gong)作(zuo)(zuo)，比如進行(xing)(xing)繪畫、制圖、更正(zheng)或(huo)者標注文檔等(deng)，也可對(dui)相關會議或(huo)談(tan)話現(xian)(xian)(xian)場(chang)進行(xing)(xing)快(kuai)速記(ji)錄等(deng)。
五、電容筆的工作原理
要知道電(dian)(dian)容(rong)(rong)筆(bi)的(de)(de)工(gong)作(zuo)原理(li)(li)，首先(xian)要了解與電(dian)(dian)容(rong)(rong)筆(bi)配套使用的(de)(de)電(dian)(dian)容(rong)(rong)屏(ping)的(de)(de)原理(li)(li)：電(dian)(dian)容(rong)(rong)屏(ping)是利(li)用人(ren)(ren)(ren)體(ti)(ti)(ti)(ti)的(de)(de)電(dian)(dian)流(liu)(liu)(liu)感應工(gong)作(zuo)的(de)(de)，電(dian)(dian)容(rong)(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)利(li)用人(ren)(ren)(ren)體(ti)(ti)(ti)(ti)的(de)(de)電(dian)(dian)流(liu)(liu)(liu)感應進行工(gong)作(zuo)，當手(shou)指觸(chu)(chu)摸(mo)(mo)在(zai)金(jin)屬層上時，由于(yu)人(ren)(ren)(ren)體(ti)(ti)(ti)(ti)電(dian)(dian)場、用戶和(he)觸(chu)(chu)控(kong)屏(ping)表面形成以一(yi)個(ge)耦合電(dian)(dian)容(rong)(rong)，對(dui)于(yu)高頻電(dian)(dian)流(liu)(liu)(liu)來說，電(dian)(dian)容(rong)(rong)是直接導體(ti)(ti)(ti)(ti)，于(yu)是手(shou)指從接觸(chu)(chu)點(dian)吸走一(yi)個(ge)很小的(de)(de)電(dian)(dian)流(liu)(liu)(liu)。這(zhe)(zhe)個(ge)電(dian)(dian)流(liu)(liu)(liu)分別從觸(chu)(chu)控(kong)屏(ping)四(si)(si)角上的(de)(de)電(dian)(dian)極(ji)中流(liu)(liu)(liu)出，并且流(liu)(liu)(liu)經這(zhe)(zhe)四(si)(si)個(ge)電(dian)(dian)極(ji)的(de)(de)電(dian)(dian)流(liu)(liu)(liu)與手(shou)指到四(si)(si)角的(de)(de)距(ju)離成正比，控(kong)制器通過(guo)對(dui)這(zhe)(zhe)四(si)(si)個(ge)電(dian)(dian)流(liu)(liu)(liu)比例的(de)(de)精確計(ji)算(suan)，得(de)出觸(chu)(chu)摸(mo)(mo)點(dian)的(de)(de)位(wei)置信息。電(dian)(dian)容(rong)(rong)筆(bi)就是通過(guo)導體(ti)(ti)(ti)(ti)模擬人(ren)(ren)(ren)體(ti)(ti)(ti)(ti)手(shou)指，筆(bi)尖觸(chu)(chu)摸(mo)(mo)電(dian)(dian)容(rong)(rong)屏(ping)時同樣產(chan)生電(dian)(dian)流(liu)(liu)(liu)，控(kong)制器對(dui)電(dian)(dian)流(liu)(liu)(liu)計(ji)算(suan)得(de)出觸(chu)(chu)摸(mo)(mo)信息，并完(wan)成操(cao)作(zuo)。
