一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)是利用(yong)(yong)(yong)導(dao)體材(cai)料(liao)制作的(de)(de)(de)(de)具(ju)有(you)(you)的(de)(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)特性，用(yong)(yong)(yong)來在(zai)觸控(kong)電(dian)(dian)(dian)(dian)容(rong)(rong)式屏(ping)(ping)幕(mu)完成人(ren)機(ji)對話操(cao)作用(yong)(yong)(yong)的(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)，是利用(yong)(yong)(yong)導(dao)體材(cai)料(liao)模仿人(ren)體（通常是手(shou)指）完成人(ren)機(ji)對話一種輔助裝置。觸控(kong)筆(bi)(bi)(bi)(bi)(bi)是一種小筆(bi)(bi)(bi)(bi)(bi)形的(de)(de)(de)(de)工(gong)具(ju)，用(yong)(yong)(yong)來輸入(ru)指令到(dao)電(dian)(dian)(dian)(dian)腦屏(ping)(ping)幕(mu)、移動設備、繪圖板(ban)等(deng)具(ju)有(you)(you)觸摸(mo)屏(ping)(ping)的(de)(de)(de)(de)設備，用(yong)(yong)(yong)戶可以通過觸控(kong)筆(bi)(bi)(bi)(bi)(bi)點擊觸控(kong)屏(ping)(ping)幕(mu)來選取文(wen)件或繪畫。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和(he)觸控(kong)筆(bi)(bi)(bi)(bi)(bi)兩者的(de)(de)(de)(de)區別(bie)在(zai)導(dao)體材(cai)料(liao)、作用(yong)(yong)(yong)機(ji)制和(he)適(shi)用(yong)(yong)(yong)對象的(de)(de)(de)(de)不同：電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)頭帶有(you)(you)靜(jing)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)幕(mu)本身有(you)(you)感應(ying)靜(jing)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)技術特點，所以電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)；而普(pu)通的(de)(de)(de)(de)觸控(kong)筆(bi)(bi)(bi)(bi)(bi)是靠按壓屏(ping)(ping)幕(mu)，適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)阻屏(ping)(ping)。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和(he)觸控(kong)筆(bi)(bi)(bi)(bi)(bi)哪個好，寫字繪畫用(yong)(yong)(yong)哪種筆(bi)(bi)(bi)(bi)(bi)主(zhu)要要根據(ju)選擇的(de)(de)(de)(de)產品來看，不同的(de)(de)(de)(de)屏(ping)(ping)幕(mu)適(shi)應(ying)不同的(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)：觸控(kong)筆(bi)(bi)(bi)(bi)(bi)主(zhu)要適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)阻屏(ping)(ping)，電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)，現在(zai)的(de)(de)(de)(de)平板(ban)、手(shou)機(ji)等(deng)設備基本上都(dou)是用(yong)(yong)(yong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)，因此一般現在(zai)用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)比(bi)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(wai)，還(huan)要注意(yi)考慮電容筆的防誤(wu)觸功(gong)能、延遲、筆尖材(cai)質、續航能力、有無壓感功(gong)能等(deng)方面。

三、電容筆怎么連接平板

電(dian)容(rong)筆分為被(bei)動(dong)式(shi)電(dian)容(rong)筆和主動(dong)式(shi)電(dian)容(rong)筆，被(bei)動(dong)式(shi)電(dian)容(rong)筆可(ke)(ke)以(yi)直接(jie)用，主動(dong)式(shi)電(dian)容(rong)筆內置(zhi)芯片，需要(yao)連(lian)接(jie)才能使(shi)用，連(lian)接(jie)方法(fa)很(hen)簡(jian)單：1、將(jiang)手寫筆放(fang)在平板(ban)附近，拉(la)下狀態欄，將(jiang)藍牙(ya)打(da)開(kai)，再長按“藍牙(ya)”，進(jin)入藍牙(ya)界(jie)面。2、這時，藍牙(ya)會自動(dong)彈(dan)出連(lian)接(jie)界(jie)面，點擊(ji)“連(lian)接(jie)”即可(ke)(ke)，如果沒(mei)有(you)彈(dan)出，也可(ke)(ke)以(yi)在藍牙(ya)搜索界(jie)面里找到手寫筆的ID，然后連(lian)接(jie)。3、連(lian)接(jie)好后，手寫筆就可(ke)(ke)以(yi)使(shi)用了。

四、電容筆是干什么用的

電容(rong)筆(bi)(bi)在最初出(chu)現的(de)(de)時候，較(jiao)為(wei)普遍地使(shi)用(yong)在部分(fen)帶有觸屏(ping)功(gong)能(neng)的(de)(de)手機上(shang)，可(ke)以(yi)(yi)用(yong)電容(rong)筆(bi)(bi)進行操作(zuo)(zuo)，用(yong)于操作(zuo)(zuo)對應的(de)(de)屏(ping)幕(mu)上(shang)方功(gong)能(neng)按鈕，以(yi)(yi)達到(dao)使(shi)用(yong)者的(de)(de)目的(de)(de)。由于當時技術并不(bu)先(xian)進，導致手機及平板很多功(gong)能(neng)未被開發出(chu)來，而使(shi)得電容(rong)筆(bi)(bi)的(de)(de)用(yong)途受到(dao)較(jiao)大的(de)(de)局限，不(bu)過(guo)現如(ru)今不(bu)管是(shi)硬件(jian)還是(shi)軟件(jian)技術都(dou)得到(dao)跨越性的(de)(de)提(ti)升(sheng)，電容(rong)筆(bi)(bi)的(de)(de)用(yong)途更(geng)加廣泛(fan)。現如(ru)今，隨著(zhu)更(geng)多App的(de)(de)較(jiao)完(wan)善的(de)(de)功(gong)能(neng)開發，讓(rang)電容(rong)筆(bi)(bi)的(de)(de)功(gong)能(neng)也產(chan)生(sheng)質的(de)(de)改變，不(bu)再(zai)只是(shi)用(yong)于觸控操作(zuo)(zuo)這么簡(jian)單。現如(ru)今電容(rong)筆(bi)(bi)已經可(ke)以(yi)(yi)直接(jie)在移(yi)動設備，如(ru)手機、筆(bi)(bi)記本、平板等(deng)(deng)，利用(yong)APP的(de)(de)功(gong)能(neng)開展工作(zuo)(zuo)，比(bi)如(ru)進行繪畫、制圖、更(geng)正或者標注(zhu)文檔等(deng)(deng)，也可(ke)對相關會議或談話現場(chang)進行快速記錄等(deng)(deng)。

五、電容筆的工作原理

要知(zhi)道電(dian)(dian)(dian)(dian)容筆的(de)(de)工作(zuo)原理(li)，首先(xian)要了解與(yu)(yu)電(dian)(dian)(dian)(dian)容筆配套(tao)使用(yong)(yong)的(de)(de)電(dian)(dian)(dian)(dian)容屏的(de)(de)原理(li)：電(dian)(dian)(dian)(dian)容屏是(shi)(shi)(shi)利(li)用(yong)(yong)人(ren)體的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)感應工作(zuo)的(de)(de)，電(dian)(dian)(dian)(dian)容觸(chu)摸(mo)(mo)(mo)屏利(li)用(yong)(yong)人(ren)體的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)感應進行工作(zuo)，當手指觸(chu)摸(mo)(mo)(mo)在金屬層上時，由于(yu)(yu)人(ren)體電(dian)(dian)(dian)(dian)場、用(yong)(yong)戶和(he)觸(chu)控(kong)屏表面形(xing)成以一個(ge)(ge)耦合(he)電(dian)(dian)(dian)(dian)容，對于(yu)(yu)高頻(pin)電(dian)(dian)(dian)(dian)流(liu)(liu)來說，電(dian)(dian)(dian)(dian)容是(shi)(shi)(shi)直接(jie)導體，于(yu)(yu)是(shi)(shi)(shi)手指從(cong)接(jie)觸(chu)點(dian)吸走一個(ge)(ge)很小的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)。這(zhe)個(ge)(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)分別從(cong)觸(chu)控(kong)屏四(si)角上的(de)(de)電(dian)(dian)(dian)(dian)極(ji)中(zhong)流(liu)(liu)出(chu)，并(bing)且流(liu)(liu)經這(zhe)四(si)個(ge)(ge)電(dian)(dian)(dian)(dian)極(ji)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)與(yu)(yu)手指到四(si)角的(de)(de)距離成正(zheng)比，控(kong)制器通(tong)過對這(zhe)四(si)個(ge)(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)比例的(de)(de)精確計算(suan)，得(de)出(chu)觸(chu)摸(mo)(mo)(mo)點(dian)的(de)(de)位(wei)置(zhi)信(xin)息。電(dian)(dian)(dian)(dian)容筆就(jiu)是(shi)(shi)(shi)通(tong)過導體模擬人(ren)體手指，筆尖觸(chu)摸(mo)(mo)(mo)電(dian)(dian)(dian)(dian)容屏時同樣產(chan)生(sheng)電(dian)(dian)(dian)(dian)流(liu)(liu)，控(kong)制器對電(dian)(dian)(dian)(dian)流(liu)(liu)計算(suan)得(de)出(chu)觸(chu)摸(mo)(mo)(mo)信(xin)息，并(bing)完成操(cao)作(zuo)。
