一、電容筆和觸控筆的區別

電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)是(shi)利用(yong)(yong)(yong)(yong)導(dao)(dao)體材(cai)料制(zhi)(zhi)作(zuo)的(de)(de)具有(you)的(de)(de)導(dao)(dao)電(dian)(dian)(dian)特性(xing)，用(yong)(yong)(yong)(yong)來在觸(chu)控(kong)(kong)電(dian)(dian)(dian)容(rong)(rong)式屏(ping)(ping)(ping)幕完(wan)成人(ren)機對話(hua)操作(zuo)用(yong)(yong)(yong)(yong)的(de)(de)筆(bi)(bi)(bi)，是(shi)利用(yong)(yong)(yong)(yong)導(dao)(dao)體材(cai)料模仿人(ren)體（通常是(shi)手指）完(wan)成人(ren)機對話(hua)一(yi)種(zhong)輔(fu)助裝(zhuang)置(zhi)。觸(chu)控(kong)(kong)筆(bi)(bi)(bi)是(shi)一(yi)種(zhong)小筆(bi)(bi)(bi)形的(de)(de)工具，用(yong)(yong)(yong)(yong)來輸(shu)入指令到電(dian)(dian)(dian)腦屏(ping)(ping)(ping)幕、移動設(she)備(bei)、繪圖板等(deng)具有(you)觸(chu)摸屏(ping)(ping)(ping)的(de)(de)設(she)備(bei)，用(yong)(yong)(yong)(yong)戶(hu)可(ke)以(yi)通過觸(chu)控(kong)(kong)筆(bi)(bi)(bi)點擊觸(chu)控(kong)(kong)屏(ping)(ping)(ping)幕來選取(qu)文件或繪畫。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)控(kong)(kong)筆(bi)(bi)(bi)兩者的(de)(de)區別在導(dao)(dao)體材(cai)料、作(zuo)用(yong)(yong)(yong)(yong)機制(zhi)(zhi)和(he)適(shi)用(yong)(yong)(yong)(yong)對象的(de)(de)不同(tong)：電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)筆(bi)(bi)(bi)頭帶有(you)靜電(dian)(dian)(dian)，電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)幕本(ben)身(shen)有(you)感應(ying)靜電(dian)(dian)(dian)的(de)(de)技術特點，所以(yi)電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)；而普通的(de)(de)觸(chu)控(kong)(kong)筆(bi)(bi)(bi)是(shi)靠按壓屏(ping)(ping)(ping)幕，適(shi)用(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)阻屏(ping)(ping)(ping)。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)控(kong)(kong)筆(bi)(bi)(bi)哪個好(hao)，寫字繪畫用(yong)(yong)(yong)(yong)哪種(zhong)筆(bi)(bi)(bi)主要(yao)要(yao)根據選擇的(de)(de)產(chan)品(pin)來看，不同(tong)的(de)(de)屏(ping)(ping)(ping)幕適(shi)應(ying)不同(tong)的(de)(de)筆(bi)(bi)(bi)：觸(chu)控(kong)(kong)筆(bi)(bi)(bi)主要(yao)適(shi)用(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)阻屏(ping)(ping)(ping)，電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)(yong)于電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)，現在的(de)(de)平板、手機等(deng)設(she)備(bei)基本(ben)上都(dou)是(shi)用(yong)(yong)(yong)(yong)的(de)(de)電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)，因此一(yi)般現在用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)比(bi)較(jiao)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(wai)，還要注意(yi)考慮電容(rong)筆的防誤(wu)觸功能(neng)(neng)、延遲、筆尖材質、續航能(neng)(neng)力、有無(wu)壓感功能(neng)(neng)等方面。

三、電容筆怎么連接平板

電容(rong)(rong)筆分為被(bei)動(dong)(dong)式電容(rong)(rong)筆和主動(dong)(dong)式電容(rong)(rong)筆，被(bei)動(dong)(dong)式電容(rong)(rong)筆可(ke)(ke)以直接(jie)用，主動(dong)(dong)式電容(rong)(rong)筆內置芯片，需要連(lian)(lian)接(jie)才能使(shi)用，連(lian)(lian)接(jie)方法很簡單：1、將手寫(xie)筆放在(zai)平板附近，拉下狀態欄，將藍牙打開，再長(chang)按“藍牙”，進入藍牙界面。2、這時，藍牙會自動(dong)(dong)彈(dan)出連(lian)(lian)接(jie)界面，點擊“連(lian)(lian)接(jie)”即可(ke)(ke)，如果沒(mei)有(you)彈(dan)出，也可(ke)(ke)以在(zai)藍牙搜索界面里找到手寫(xie)筆的ID，然后(hou)連(lian)(lian)接(jie)。3、連(lian)(lian)接(jie)好后(hou)，手寫(xie)筆就(jiu)可(ke)(ke)以使(shi)用了。

四、電容筆是干什么用的

電(dian)(dian)容(rong)(rong)筆在(zai)最初出(chu)(chu)現(xian)的(de)(de)(de)(de)(de)時候，較(jiao)為普遍(bian)地使(shi)(shi)用(yong)在(zai)部(bu)分(fen)帶有觸(chu)(chu)屏(ping)功(gong)(gong)能的(de)(de)(de)(de)(de)手機上(shang)，可以用(yong)電(dian)(dian)容(rong)(rong)筆進行操(cao)作，用(yong)于(yu)操(cao)作對應的(de)(de)(de)(de)(de)屏(ping)幕(mu)上(shang)方功(gong)(gong)能按鈕，以達到(dao)使(shi)(shi)用(yong)者(zhe)(zhe)的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。由于(yu)當(dang)時技(ji)術(shu)并不(bu)先進，導(dao)致手機及(ji)平(ping)(ping)板很多(duo)(duo)功(gong)(gong)能未被開發出(chu)(chu)來，而使(shi)(shi)得電(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)(de)用(yong)途(tu)(tu)受到(dao)較(jiao)大(da)的(de)(de)(de)(de)(de)局(ju)限，不(bu)過現(xian)如(ru)今(jin)(jin)不(bu)管是(shi)硬件還是(shi)軟件技(ji)術(shu)都(dou)得到(dao)跨越(yue)性的(de)(de)(de)(de)(de)提升，電(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)(de)用(yong)途(tu)(tu)更加廣泛。現(xian)如(ru)今(jin)(jin)，隨著更多(duo)(duo)App的(de)(de)(de)(de)(de)較(jiao)完(wan)善的(de)(de)(de)(de)(de)功(gong)(gong)能開發，讓電(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)(de)功(gong)(gong)能也(ye)產生(sheng)質的(de)(de)(de)(de)(de)改變，不(bu)再只是(shi)用(yong)于(yu)觸(chu)(chu)控(kong)操(cao)作這么簡單。現(xian)如(ru)今(jin)(jin)電(dian)(dian)容(rong)(rong)筆已經可以直接在(zai)移動設備，如(ru)手機、筆記本(ben)、平(ping)(ping)板等(deng)，利用(yong)APP的(de)(de)(de)(de)(de)功(gong)(gong)能開展工(gong)作，比如(ru)進行繪畫、制圖、更正或者(zhe)(zhe)標注文檔等(deng)，也(ye)可對相關會議或談話(hua)現(xian)場進行快速記錄(lu)等(deng)。

五、電容筆的工作原理

要知(zhi)道電(dian)(dian)容(rong)(rong)筆(bi)的(de)工作原理，首先要了解與(yu)電(dian)(dian)容(rong)(rong)筆(bi)配套使用(yong)(yong)的(de)電(dian)(dian)容(rong)(rong)屏(ping)(ping)的(de)原理：電(dian)(dian)容(rong)(rong)屏(ping)(ping)是利(li)用(yong)(yong)人(ren)體(ti)(ti)(ti)的(de)電(dian)(dian)流(liu)感應(ying)工作的(de)，電(dian)(dian)容(rong)(rong)觸(chu)(chu)摸屏(ping)(ping)利(li)用(yong)(yong)人(ren)體(ti)(ti)(ti)的(de)電(dian)(dian)流(liu)感應(ying)進行(xing)工作，當手指(zhi)(zhi)觸(chu)(chu)摸在金屬層上時，由于(yu)人(ren)體(ti)(ti)(ti)電(dian)(dian)場、用(yong)(yong)戶(hu)和(he)觸(chu)(chu)控屏(ping)(ping)表面形(xing)成以一個耦合電(dian)(dian)容(rong)(rong)，對(dui)于(yu)高頻電(dian)(dian)流(liu)來說，電(dian)(dian)容(rong)(rong)是直接導(dao)體(ti)(ti)(ti)，于(yu)是手指(zhi)(zhi)從接觸(chu)(chu)點吸走(zou)一個很小的(de)電(dian)(dian)流(liu)。這個電(dian)(dian)流(liu)分別從觸(chu)(chu)控屏(ping)(ping)四(si)(si)角上的(de)電(dian)(dian)極中流(liu)出(chu)，并且流(liu)經(jing)這四(si)(si)個電(dian)(dian)極的(de)電(dian)(dian)流(liu)與(yu)手指(zhi)(zhi)到四(si)(si)角的(de)距離成正比，控制(zhi)器通(tong)過對(dui)這四(si)(si)個電(dian)(dian)流(liu)比例的(de)精確(que)計(ji)算(suan)，得出(chu)觸(chu)(chu)摸點的(de)位置信息(xi)。電(dian)(dian)容(rong)(rong)筆(bi)就是通(tong)過導(dao)體(ti)(ti)(ti)模擬(ni)人(ren)體(ti)(ti)(ti)手指(zhi)(zhi)，筆(bi)尖(jian)觸(chu)(chu)摸電(dian)(dian)容(rong)(rong)屏(ping)(ping)時同樣產生(sheng)電(dian)(dian)流(liu)，控制(zhi)器對(dui)電(dian)(dian)流(liu)計(ji)算(suan)得出(chu)觸(chu)(chu)摸信息(xi)，并完(wan)成操作。
