一、電容筆和觸控筆的區別
電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)是(shi)(shi)利用(yong)(yong)(yong)(yong)(yong)導(dao)體(ti)材料制作(zuo)的(de)(de)(de)具(ju)有的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)特性(xing)，用(yong)(yong)(yong)(yong)(yong)來(lai)在觸(chu)控電(dian)(dian)(dian)(dian)容(rong)(rong)式屏(ping)幕(mu)(mu)完(wan)成(cheng)人(ren)機(ji)(ji)對話(hua)操作(zuo)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)筆(bi)(bi)，是(shi)(shi)利用(yong)(yong)(yong)(yong)(yong)導(dao)體(ti)材料模仿(fang)人(ren)體(ti)（通(tong)(tong)常是(shi)(shi)手指）完(wan)成(cheng)人(ren)機(ji)(ji)對話(hua)一種(zhong)輔助裝置。觸(chu)控筆(bi)(bi)是(shi)(shi)一種(zhong)小筆(bi)(bi)形的(de)(de)(de)工(gong)具(ju)，用(yong)(yong)(yong)(yong)(yong)來(lai)輸(shu)入(ru)指令到電(dian)(dian)(dian)(dian)腦屏(ping)幕(mu)(mu)、移(yi)動設備(bei)、繪圖板等具(ju)有觸(chu)摸屏(ping)的(de)(de)(de)設備(bei)，用(yong)(yong)(yong)(yong)(yong)戶可以(yi)通(tong)(tong)過觸(chu)控筆(bi)(bi)點(dian)擊(ji)觸(chu)控屏(ping)幕(mu)(mu)來(lai)選取文件或繪畫。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)和觸(chu)控筆(bi)(bi)兩者的(de)(de)(de)區別在導(dao)體(ti)材料、作(zuo)用(yong)(yong)(yong)(yong)(yong)機(ji)(ji)制和適(shi)用(yong)(yong)(yong)(yong)(yong)對象的(de)(de)(de)不(bu)同(tong)(tong)：電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)筆(bi)(bi)頭帶有靜電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)幕(mu)(mu)本身有感(gan)應靜電(dian)(dian)(dian)(dian)的(de)(de)(de)技術特點(dian)，所以(yi)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)適(shi)用(yong)(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)；而普通(tong)(tong)的(de)(de)(de)觸(chu)控筆(bi)(bi)是(shi)(shi)靠按壓屏(ping)幕(mu)(mu)，適(shi)用(yong)(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)阻(zu)屏(ping)。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)和觸(chu)控筆(bi)(bi)哪(na)個(ge)好(hao)，寫字繪畫用(yong)(yong)(yong)(yong)(yong)哪(na)種(zhong)筆(bi)(bi)主(zhu)(zhu)要要根據選擇的(de)(de)(de)產品來(lai)看，不(bu)同(tong)(tong)的(de)(de)(de)屏(ping)幕(mu)(mu)適(shi)應不(bu)同(tong)(tong)的(de)(de)(de)筆(bi)(bi)：觸(chu)控筆(bi)(bi)主(zhu)(zhu)要適(shi)用(yong)(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)阻(zu)屏(ping)，電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)適(shi)用(yong)(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，現在的(de)(de)(de)平板、手機(ji)(ji)等設備(bei)基(ji)本上都是(shi)(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，因此一般現在用(yong)(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(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(lv)電容(rong)筆的防誤觸功能、延(yan)遲、筆尖(jian)材質(zhi)、續航(hang)能力、有(you)無壓(ya)感功能等方(fang)面(mian)。
三、電容筆怎么連接平板
電(dian)容(rong)筆分為被動式(shi)電(dian)容(rong)筆和(he)主動式(shi)電(dian)容(rong)筆，被動式(shi)電(dian)容(rong)筆可以直接(jie)用(yong)，主動式(shi)電(dian)容(rong)筆內(nei)置芯片，需(xu)要連接(jie)才(cai)能(neng)使用(yong)，連接(jie)方法很(hen)簡單：1、將(jiang)手(shou)寫(xie)(xie)筆放在平板附近，拉下狀態欄(lan)，將(jiang)藍(lan)牙打開，再長按“藍(lan)牙”，進入藍(lan)牙界面(mian)。2、這時，藍(lan)牙會自動彈出(chu)連接(jie)界面(mian)，點擊“連接(jie)”即可，如果(guo)沒(mei)有彈出(chu)，也可以在藍(lan)牙搜索界面(mian)里找到(dao)手(shou)寫(xie)(xie)筆的ID，然后(hou)(hou)連接(jie)。3、連接(jie)好后(hou)(hou)，手(shou)寫(xie)(xie)筆就可以使用(yong)了。
四、電容筆是干什么用的
電(dian)(dian)(dian)容(rong)(rong)筆在(zai)最(zui)初出(chu)現的(de)(de)(de)(de)時候(hou)，較為(wei)普遍地使(shi)用(yong)(yong)在(zai)部(bu)分帶有觸屏(ping)功(gong)能的(de)(de)(de)(de)手(shou)(shou)機(ji)上，可(ke)以用(yong)(yong)電(dian)(dian)(dian)容(rong)(rong)筆進(jin)行操作(zuo)，用(yong)(yong)于操作(zuo)對應的(de)(de)(de)(de)屏(ping)幕上方功(gong)能按鈕(niu)，以達到使(shi)用(yong)(yong)者(zhe)的(de)(de)(de)(de)目的(de)(de)(de)(de)。由于當時技術(shu)并不(bu)先進(jin)，導致手(shou)(shou)機(ji)及平板很多(duo)功(gong)能未(wei)被開發(fa)出(chu)來，而使(shi)得電(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)用(yong)(yong)途受到較大(da)的(de)(de)(de)(de)局限，不(bu)過(guo)現如今不(bu)管是硬件還是軟(ruan)件技術(shu)都(dou)得到跨越性的(de)(de)(de)(de)提升(sheng)，電(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)用(yong)(yong)途更(geng)(geng)加廣泛(fan)。現如今，隨(sui)著更(geng)(geng)多(duo)App的(de)(de)(de)(de)較完(wan)善的(de)(de)(de)(de)功(gong)能開發(fa)，讓電(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)功(gong)能也(ye)產生質的(de)(de)(de)(de)改變(bian)，不(bu)再(zai)只是用(yong)(yong)于觸控操作(zuo)這么簡(jian)單。現如今電(dian)(dian)(dian)容(rong)(rong)筆已經可(ke)以直接在(zai)移(yi)動設(she)備，如手(shou)(shou)機(ji)、筆記本(ben)、平板等，利用(yong)(yong)APP的(de)(de)(de)(de)功(gong)能開展工作(zuo)，比(bi)如進(jin)行繪畫、制圖、更(geng)(geng)正或(huo)者(zhe)標注文檔等，也(ye)可(ke)對相關(guan)會(hui)議或(huo)談(tan)話現場進(jin)行快(kuai)速記錄等。
五、電容筆的工作原理
要知道電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)工(gong)作(zuo)原理，首先(xian)要了解與(yu)電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)配套使用的(de)(de)(de)(de)電(dian)(dian)(dian)容(rong)(rong)屏(ping)的(de)(de)(de)(de)原理：電(dian)(dian)(dian)容(rong)(rong)屏(ping)是利用人(ren)體(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)感應工(gong)作(zuo)的(de)(de)(de)(de)，電(dian)(dian)(dian)容(rong)(rong)觸(chu)(chu)摸(mo)屏(ping)利用人(ren)體(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)感應進(jin)行(xing)工(gong)作(zuo)，當手(shou)指(zhi)觸(chu)(chu)摸(mo)在(zai)金屬層(ceng)上(shang)時，由于人(ren)體(ti)電(dian)(dian)(dian)場、用戶和觸(chu)(chu)控(kong)屏(ping)表面形成(cheng)以一(yi)(yi)個(ge)耦合電(dian)(dian)(dian)容(rong)(rong)，對于高(gao)頻電(dian)(dian)(dian)流(liu)來說，電(dian)(dian)(dian)容(rong)(rong)是直接(jie)導體(ti)，于是手(shou)指(zhi)從(cong)接(jie)觸(chu)(chu)點吸走一(yi)(yi)個(ge)很小的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)。這個(ge)電(dian)(dian)(dian)流(liu)分別從(cong)觸(chu)(chu)控(kong)屏(ping)四(si)角上(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)極中流(liu)出(chu)，并且流(liu)經這四(si)個(ge)電(dian)(dian)(dian)極的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)與(yu)手(shou)指(zhi)到四(si)角的(de)(de)(de)(de)距(ju)離成(cheng)正比，控(kong)制器通過(guo)對這四(si)個(ge)電(dian)(dian)(dian)流(liu)比例的(de)(de)(de)(de)精(jing)確計算(suan)，得(de)出(chu)觸(chu)(chu)摸(mo)點的(de)(de)(de)(de)位置(zhi)信息。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)就是通過(guo)導體(ti)模擬人(ren)體(ti)手(shou)指(zhi)，筆(bi)(bi)尖觸(chu)(chu)摸(mo)電(dian)(dian)(dian)容(rong)(rong)屏(ping)時同樣產生電(dian)(dian)(dian)流(liu)，控(kong)制器對電(dian)(dian)(dian)流(liu)計算(suan)得(de)出(chu)觸(chu)(chu)摸(mo)信息，并完(wan)成(cheng)操作(zuo)。
